The CR-7 was came out in late 1985, with a rubber idler. The gear idler became standard after S/N 10500 or so -- probably, in the very late 80s or early 90s. The BX-300 was in production in 1884 to 1887. I would guess that it never came out with a gear idler or, if it did, it was right at its very end of life. -- Ron Eric Jacobs wrote: > Did the BX-300 ever come from the factory with the gear drive, or was > this only available as an upgrade?

The AutoPlay is a two button command on the LX-5 and ZX-7 that will execute once, press and hold Rewind (or F.F.) then tap Record.  It will rewind (or F.F.) to counter Zero and automatically go into play.  This was a previously unknown function to me and I have a ZX-7. SJ ________________________________ From: Antoine Deschênes To: Talk about Nakamichi Cassette Decks Sent: Tuesday, March 31, 2009 1:54:20 PM Subject: Re: [naktalk] Which decks have AutoPlay? Isn't that equivalent to "Memory Stop" + Play, or "Memory Play" found even on cheap CR and BX decks? Le 2009-03-31 13:18, Scott Johnson a écrit : So far I've found out that the LX-5 and ZX-7 have this auto play feature.  I assume the ZX-9 has it too.  What other decks have this feature and who has used it? In case you don't know the Auto play feature is activated by pressing Rew or F.F. and while that is pressed, tap the Rec. button.  This will then automatically play when the counter hits zero or the tape hits the ends.  SJ ________________________________ ========---------------------------------------------------------========= Also check out the wiki! http://www.naks.com/wiki ========---------------------------------------------------------========= Naktalk at naks.com mailinglist Maintain your account here: http://www.naks.com/mailman/listinfo/naktalk ========---------------------------------------------------------========= -------------- next part -------------- An HTML attachment was scrubbed...

As you may know, these work by the means of a pulse train generated by the light of a bulb opening a photo-transistor. If this pulse train stops, the shut-off is triggered. This bulb, is an incandescet 12V 25mA, prone to fail. A quick replacement of this bulb will solve the problem, but once a led kit has been installed it will last forever. I have tried this on my DRAGON, and it just works. Very simple: get to the sensors, replace the 100Ohm fuse resistors with a 3K3 - 4K7 resistor, and the bulb with a 3mm white or warm white led. Note the long pin in the LED is the anode, and should be connected to the +12V. The +12V comes trough the above replaced resistor, so it's easy to identify. Other value series resistor may not work, as too much or too little light may render the pulse train unusable. The cassette well lamp has also been replace. This one with a 5mm warm white + 500Ohm resistor. Note this bulb in the DRAGON is connected to the -12V rial in my unit. Red wire is ground, and brown is -12V. LED anode should be connected trough the 500Ohm resistor to ground. Once the LED is in place, make sure you bend it towards the photo- transistor, as the llight is pretty much directional.

I have been doing the same for several months now with every "classic" transport I see for service just to insure that I don't get any recalls for the shut off lamp dying. The resistor value is not critical and can vary from 1K to 10K without a problem. When using the same warm white LED as an indicator you have to be much more careful. I usually install the LED then off wire to a resistor substitution box to get a matching intensity. You will find that the color temperature isn't exactly the same as the incandescent lamp. I usually try to change a whole section of lamps at the same time to keep the look even.

Reference voltage is 0 <> .05 % does not change in play mode. (Should be -4 Volts in play at TP1) FF and RW function properly at voltage so issue is not motor control transistors.

I have seen on the net that this problem is not unique to my Dragon; however I have found no solutions posted. Before I go to the extreme of replacing a 42 pin micro processor that is unit specific, "LM6402A-052" to Nakamichi (it also comes in LX-3's and ZX-7's) I was hoping that there is a different solution. Maybe a work around that some one else has come up with maybe I missed something. I fear that surgery of this type might be a 2 day trip into hell. Any suggestions? PS Thanks for the POO manual this would be impossible to even try to fix with out it. Chris -------------- next part -------------- An HTML attachment was scrubbed...

After pressing Pause during play, is one of the Play LEDs supposed to remain lit? If so, your circuit will keep driving the reel motor when in pause, which may be not what you want. Second, you may wish to power the V+ and VL pins off +12V and +5V respectively (V- at ground or -12V). Third, I am not sure why you need the 2N3609 transistor. Why not drive the DG419 directly from the Lplay line and swap the switch sections? Granted, I haven't gone over the DG419 data and app notes, so I may be wrong. These are just random questions that popped up as I was looking at your circuit.

Problem: Unit seams to be functional in all modes except play. In play mode all systems function but reel motor control does not take up tape in either direction. Reference voltage is 0 <> .05 % does not change in play mode. (Should be -4 Volts in play at TP1) FF and RW function properly at voltage so issue is not motor control transistors. (Changed anyway) Motor control op amp (IC603) checked fine (Changed anyway) Inverting control transistors checked fine (Q605 - Q608) (Changed anyway) Primary control transistor checked fine (Q604) (Changed anyway) Cam control looks good all other functions in play mode correct. VR601 tested good. Gate on IC605 looks to be correct in all functions save play. Problem remains. Logic tests. Pins on IC601 test fine on input side. Read Correctly Pins on IC601 on output side FF and Rewind are as per POO manual BUT pin 28 (Play Control) has no status change in play mode remains low. Play mode reads as follows. Pin 26 - Rewind - L Pin 27 - Fast Forward - L Pin 28 - Play - L *** according to the POO Manual this should go OPEN triggering Q604 *** Now for my next step .. I have seen on the net that this problem is not unique to my Dragon; however I have found no solutions posted. Before I go to the extreme of replacing a 42 pin micro processor that is unit specific, "LM6402A-052" to Nakamichi (it also comes in LX-3's and ZX-7's) I was hoping that there is a different solution. Maybe a work around that some one else has come up with maybe I missed something. I fear that surgery of this type might be a 2 day trip into hell. Any suggestions?

This came with no instructions at all. I don't know if the cleaner is suppossed to be applied to the cassette, then the cassette inserted and played? Or, the cleaner used only without the cassette and the cassette used dry? This came without instructions, and there are no instructions online. Not a very well supported product, in my opinion, when it comes without instructions. Anyways, anyone else try this product and know the correct application?

Problem: Unit seams to be functional in all modes except play. In play mode all systems function but reel motor control does not take up tape in either direction. Reference voltage is 0 <> .05 % does not change in play mode. (Should be -4 Volts in play at TP1) FF and RW function properly at voltage so issue is not motor control transistors. (Changed anyway) Motor control op amp (IC603) checked fine (Changed anyway) Inverting control transistors checked fine (Q605 - Q608) (Changed anyway) Primary control transistor checked fine (Q604) (Changed anyway) Cam control looks good all other functions in play mode correct. VR601 tested good. Gate on IC605 looks to be correct in all functions save play. Problem remains. Logic tests. Pins on IC601 test fine on input side. Read Correctly Pins on IC601 on output side FF and Rewind are as per POO manual BUT pin 28 (Play Control) has no status change in play mode remains low. Play mode reads as follows. Pin 26 - Rewind - L Pin 27 - Fast Forward - L Pin 28 - Play - L *** according to the POO Manual this should go OPEN triggering Q604 *** Now for my next step .. I have seen on the net that this problem is not unique to my Dragon; however I have found no solutions posted. Before I go to the extreme of replacing a 42 pin micro processor that is unit specific, "LM6402A-052" to Nakamichi (it also comes in LX-3's and ZX-7's) I was hoping that there is a different solution. Maybe a work around that some one else has come up with maybe I missed something. I fear that surgery of this type might be a 2 day trip into hell. Any suggestions? PS Thanks for the POO manual this would be impossible to even try to fix with out it. Chris -------------- next part -------------- An HTML attachment was scrubbed...

Message-ID: I ordered the American Recorder Cassette Cleaner from their site and recieved it yesterday. I thought it looked intersting and worth a try...if it makes cleaning easier, then all the better. It comes as a kit, which includes a cassette with some sort of tape loaded inside, a bottle of their S-721-H tape head/pinch roller cleaner (excellent stuff) and a "dropper" cap for the bottle of cleaner. My problem is, it did not come with any instructions. I looked at thei online site, and none are to be found. I sent an email yesterday, but probably won't get an answer until Monday. Because of the special included "dropper" cap, I'm assuming that the cleaner is used with the cassette? But, maybe not? The only cassette type head cleaners I have ever seen where dry type. I'm not going to use this until I get instructions... I know... I know.. not the typical "Manly" way of doing things Has anyone here ever used this product, and if so, what were your thoughts about it? Also, what procedure was recommended?

You will need quite a lot of service . Transport needs dismantling, some lubrication on mode cam, probably new idler + belts (cam and azimuth). Alignment of heads is the required. After you have all mechanical problems solved, a full electronic calibration will be needed: the Dragon is a complex machine. I have not found bad PP caps in the Dragon yet, but they can surely fail.

This allows the close to immediate testing of their task. The best cleaner for cured rubber products is water and dish soap. I know this sounds strange and has its own dangers. I think what I meant to say is that the use of solvents should be reserved for certain circumstances and not for weekly or monthly maintaince. I worked in a development lab and the use of solvents can reduce the proprieties of rubber.

Hi Richard, Yes, the cleaner is used with the cassette. put three to four drops on the felt cleaner pads, put the cassette in the deck, press play, and run the cleaner for about twenty to thirty seconds. Replace pad when visibly soiled. Although this is the best of the cassette-style cleaners, I still prefer using cotton swabs and S-721H cleaner fluid on my deck. I have found cleaner cassettes don't do as good a job as you can do by hand. This cleaner cassette is best used for decks that make accessing the heads and pinch roller difficult, especially automobile cassette players.

It was under a different name at the time, 1986 or so. It was stated on the package that this tape and cleaner was the only officially approved cleaner by Nakamichi Corp. for their cassette decks.  Eventually as time went on, to almost current date, guys like Kurt at US Recording, stated that this was the replacement for the formula I used years ago, that was the supposed best, and approved by Nakamichi as their own cleaner used by Nakamichi Repair in California.                And yes, you do apply the cleaner to the Tape, then let the tape do its thing.  I along with Kermit, feel it was more for convience, especially for cassette players in Cars, where the average user doesn't know how to get to the heads, or even want to.            I was emailed along time ago, by an Authorized Technician for many Manufacturers, such as AKAI, Tandberg, Revox, Technics, Pioneer, etc...and was told to buy this to use specifically on my Pinch Rollers.  So, I did, after hearing much about it from Kurt at US Recording........I was not at all pleased with this product.  The reason it was recommended to me just for rollers, and not so much for heads, was it is not powerful enough to clean heads, especially on a reel to reel machine, that may accumulate more dirt on heads, or possibly sticky shed tapes.....but that it was safe for Rubber rollers.  I find that it evaporates way too fast, and doesn't clean even the pinch rollers as well as the old TEAC Rubber cleaner once did.  I still have some of this TEAC stuff left, luckily. Plus I have a Rubber Cleaner/Rejuvenator from the Reel Pro Sound Guys on the Internet.  They sell a great Maintenance Kit, with various cleaners for heads, rubber, and lubricants and cleaners for Pots...etc...their product seems to be almost as good as the TEAC Rubber Cleaner.  But I personally dont care the the American Recorder product.....maybe its ok, if the heads never come in contact with a bad tape, or anything that may come off an older tape and accumulate on the heads.   Ray ----- Original Message ----- From: naktalk-request at naks.com To: naktalk at naks.com Sent: Sunday, April 5, 2009 6:03:55 AM GMT -05:00 US/Canada Eastern Subject: Naktalk Digest, Vol 74, Issue 6 Send Naktalk mailing list submissions to         naktalk at naks.com To subscribe or unsubscribe via the World Wide Web, visit         http://www.naks.com/mailman/listinfo/naktalk or, via email, send a message with subject or body 'help' to         naktalk-request at naks.com You can reach the person managing the list at         naktalk-owner at naks.com When replying, please edit your Subject line so it is more specific than "Re: Contents of Naktalk digest..."

I don't know if the cleaner is suppossed to be applied to the cassette, then the cassette inserted and played?

I thought it looked intersting and worth a try...if it makes cleaning easier, then all the better.   It comes as a kit, which includes a cassette with some sort of tape loaded inside, a bottle of their S-721-H tape head/pinch roller cleaner (excellent stuff) and a "dropper" cap for the bottle of cleaner.   My problem is, it did not come with any instructions. I looked at thei online site, and none are to be found. I sent an email yesterday, but probably won't get an answer until Monday. Because of the special included "dropper" cap, I'm assuming that the cleaner is used with the cassette? But, maybe not? The only cassette type head cleaners I have ever seen where dry type.   I'm not going to use this until I get instructions... I know... I know.. not the typical "Manly" way of doing things   Has anyone here ever used this product, and if so, what were your thoughts about it?

Replace pad when   visibly soiled. Although this is the best of the cassette-style cleaners, I still   prefer using cotton swabs and S-721H cleaner fluid on my deck.  I have   found cleaner cassettes don't do as good a job as you can do by hand. This cleaner cassette is best used for decks that make accessing the   heads and pinch roller difficult, especially automobile cassette   players.

I want to thank you for this once more. I decided to follow the same procedure for the second one. But I found that this one is not resetting the NAAC when the cassette door is opened. No reaction when pressed Forward or Reverse playback for centering or resetting the indicator and the pointer while the cassette door open. When a cassette is loaded and pressed any of the playback buttons azimuth motor makes a single movement to one side and stays there while the light is flashing. If I stop and open the cassette door there is no resetting and keeps its position. What will be the reason for this. Thank you.

Message-ID: Hi, all: I've been using the American Recorder Cleaner for a few years now--I find it works quite well for my running decks (which I clean and demag regularly). On stuff that I am restoring, or on dirty units, or when I feel like it, I use MEK. I bought a gallon can about 8 years ago on the advice of Stephen Sank when he worked his magic on my CR7. The stuff is a dream, and works far better than anything I have tried! Keep it away from some plastics, and take commonsense precautions (the can lives in the garage). I know some on the list feel MEK is too toxic--the literature is divided on the issue. But I try to put it in context: I have energy saving bulbs in my house (mercury), I drink Absinthe (wormwood), have the odd Cuban cigar (????), and ride a motorcycle. Life is good.....

Concentrations above the TLV may cause headache, dizziness, nausea, shortness of breath, and vomiting. Higher concentrations may cause central nervous system depression and unconsciousness. Ingestion: May produce abdominal pain, nausea. Aspiration into lungs can produce severe lung damage and is a medical emergency. Other symptoms expected to parallel inhalation. Skin Contact: Causes irritation to skin. Symptoms include redness, itching, and pain. May be absorbed through the skin with possible systemic effects. Eye Contact: Vapors are irritating to the eyes. Splashes can produce painful irritation and eye damage. Chronic Exposure: Prolonged skin contact may defat the skin and produce dermatitis. Chronic exposure may cause central nervous system effects. Aggravation of Pre-existing Conditions: Persons with pre-existing skin disorders or eye problems or impaired respiratory function may be more susceptible to the effects of the substance. _____ 4. First Aid Measures Inhalation: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention. Ingestion: Aspiration hazard. If swallowed, vomiting may occur spontaneously, but DO NOT INDUCE. If vomiting occurs, keep head below hips to prevent aspiration into lungs. Never give anything by mouth to an unconscious person. Call a physician immediately. Skin Contact: Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Get medical attention. Wash clothing before reuse. Thoroughly clean shoes before reuse. Eye Contact: Immediately flush eyes with plenty of water for at least 15 minutes, lifting upper and lower eyelids occasionally. Get medical attention. _____ 5. Fire Fighting Measures Fire: Flash point: -9C (16F) CC Autoignition temperature: 404C (759F) Flammable limits in air % by volume: lel: 1.4; uel: 11.4 Extremely Flammable. Explosion: Above flash point, vapor-air mixtures are explosive within flammable limits noted above. Vapors can flow along surfaces to distant ignition source and flash back. Contact with strong oxidizers may cause fire. Sealed containers may rupture when heated. Sensitive to static discharge. Fire Extinguishing Media: Dry chemical, foam or carbon dioxide. Water spray may be used to keep fire exposed containers cool, dilute spills to nonflammable mixtures, protect personnel attempting to stop leak and disperse vapors. Special Information: In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode. This highly flammable liquid must be kept from sparks, open flame, hot surfaces, and all sources of heat and ignition. _____ 6. Accidental Release Measures Ventilate area of leak or spill. Remove all sources of ignition. Wear appropriate personal protective equipment as specified in Section 8. Isolate hazard area. Keep unnecessary and unprotected personnel from entering. Contain and recover liquid when possible. Use non-sparking tools and equipment. Collect liquid in an appropriate container or absorb with an inert material (e. g., vermiculite, dry sand, earth), and place in a chemical waste container. Do not use combustible materials, such as saw dust. Do not flush to sewer! If a leak or spill has not ignited, use water spray to disperse the vapors, to protect personnel attempting to stop leak, and to flush spills away from exposures. US Regulations (CERCLA) require reporting spills and releases to soil, water and air in excess of reportable quantities. The toll free number for the US Coast Guard National Response Center is (800) 424-8802. J. T. Baker SOLUSORBR solvent adsorbent is recommended for spills of this product. _____ 7. Handling and Storage Protect against physical damage. Store in a cool, dry well-ventilated location, away from any area where the fire hazard may be acute. Outside or detached storage is preferred. Separate from incompatibles. Containers should be bonded and grounded for transfers to avoid static sparks. Storage and use areas should be No Smoking areas. Use non-sparking type tools and equipment, including explosion proof ventilation. Containers of this material may be hazardous when empty since they retain product residues (vapors, liquid); observe all warnings and precautions listed for the product. _____ 8. Exposure Controls/Personal Protection Airborne Exposure Limits: -OSHA Permissible Exposure Limit (PEL): 200 ppm (TWA) -ACGIH Threshold Limit Value (TLV): 200 ppm (TWA), 300 ppm (STEL) Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area. Please refer to the ACGIH document, Industrial Ventilation, A Manual of Recommended Practices, most recent edition, for details. Use explosion-proof equipment. Personal Respirators (NIOSH Approved): If the exposure limit is exceeded and engineering controls are not feasible, a full facepiece respirator with organic vapor cartridge may be worn up to 50 times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. For emergencies or instances where the exposure levels are not known, use a full-facepiece positive-pressure, air-supplied respirator. WARNING: Air purifying respirators do not protect workers in oxygen-deficient atmospheres. Skin Protection: Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as appropriate, to prevent skin contact. Butyl rubber is a suitable material for personal protective equipment. Eye Protection: Use chemical safety goggles and/or a full face shield where splashing is possible. Maintain eye wash fountain and quick-drench facilities in work area. _____ 9. Physical and Chemical Properties Appearance: Clear, colorless liquid. Odor: Sharp mint-like odor.

Hi, all: I've been using the American Recorder Cleaner for a few years now--I find it works quite well for my running decks (which I clean and demag regularly). On stuff that I am restoring, or on dirty units, or when I feel like it, I use MEK. I bought a gallon can about 8 years ago on the advice of Stephen Sank when he worked his magic on my CR7. The stuff is a dream, and works far better than anything I have tried! Keep it away from some plastics, and take commonsense precautions (the can lives in the garage). I know some on the list feel MEK is too toxic--the literature is divided on the issue. But I try to put it in context: I have energy saving bulbs in my house (mercury), I drink Absinthe (wormwood), have the odd Cuban cigar (????), and ride a motorcycle. Life is good.....

Message-ID: <15380882.1239028948495.JavaMail.root@elwamui-milano.atl.sa.earthlink.net> Gene, With all due respect, this is terrible advice. The play head is sacred! With NAAC, any mechanical head azimuth adjustment will produce an opposite adjustment by the NAAC, however most "clicking" problems are caused by tape travel, torque, or skew issues, and not azimuth alignment. An azimuth alignment tape is one tool you MUST have before adjusting heads! A check may be made by removing the Dragon's bottom cover and unplugging the 2 conductor shielded CN-5 connector on the NAAC board. First, find this connector. Second, power the Dragon ON and open the cassette holder. Confirm that the azimuth motor moves the azimuth pointer to the center position (note the black plastic ridges line up). Third, unplug CN-5. Fourth, play a known good tape and listen in mono. If there are plenty of highs and no phase sounds, especially when switching your preamp between mono and stereo, then the play azimuth is correct, and the NAAC alignment is at fault. If you hear large phase problems and a loss of treble, then azimuth MAY be one part of a larger problem(s). Many disable NAAC by unplugging CN-5(the indicators will still blink) until they can service their decks. Dragon alignment is very tricky, second only to the 681ZX, and should not be attempted casually! tom brucker -----Original Message----- >From: Gene Ess >Sent: Apr 4, 2009 12:50 PM >To: Talk about Nakamichi Cassette Decks >Subject: RE: [naktalk] Dragon with NAAC problems... skew? > >My Dragon did the same.

Although I can't take credit for the advice, as I received it from a Nak guru everyone knows here. This slight tweak completely eliminated the clicks that the NAAC showed only on some tapes and on some tapes, just side B. The audio sounds fantastic and I can not discern any performance loss because of this tweak. So I assume it worked for my deck. The deck is known to be aligned perfectly per this tech as the head positions and tape path were all restored to factory spec. So perhaps with this in mind, it is not such a terrible advice.

Gene, With all due respect, this is terrible advice. The play head is sacred! With NAAC, any mechanical head azimuth adjustment will produce an opposite adjustment by the NAAC, however most "clicking" problems are caused by tape travel, torque, or skew issues, and not azimuth alignment. An azimuth alignment tape is one tool you MUST have before adjusting heads! A check may be made by removing the Dragon's bottom cover and unplugging the 2 conductor shielded CN-5 connector on the NAAC board. First, find this connector. Second, power the Dragon ON and open the cassette holder. Confirm that the azimuth motor moves the azimuth pointer to the center position (note the black plastic ridges line up). Third, unplug CN-5. Fourth, play a known good tape and listen in mono. If there are plenty of highs and no phase sounds, especially when switching your preamp between mono and stereo, then the play azimuth is correct, and the NAAC alignment is at fault. If you hear large phase problems and a loss of treble, then azimuth MAY be one part of a larger problem(s). Many disable NAAC by unplugging CN-5(the indicators will still blink) until they can service their decks. Dragon alignment is very tricky, second only to the 681ZX, and should not be attempted casually! tom brucker -----Original Message----- >From: Gene Ess >Sent: Apr 4, 2009 12:50 PM >To: Talk about Nakamichi Cassette Decks >Subject: RE: [naktalk] Dragon with NAAC problems... skew? > >My Dragon did the same.

Today, it is banned by the Montreal Protocol. I would dispose of the s-711 by finding out if anyone is having a hazardous chemical collection. Most any of your chlorinated hydrocarbon solvents are more aggressive and more hazardous. Any solvent should be used in a well vented room. A fan and a open window. Some solvents have the fun properties like ( one that I was working with. I didn't know it was affecting me until I walked outside and passed out when I got into fresh air.). A replacement for trichloroethylene (TCE), perchlorethylene or methylene chloride, Hubbard-Hall's Hubtron PB is a stabilized n-propyl bromide (npb) product with the same characteristics and similar physical properties.

Message-ID: <26288826.1239049952905.JavaMail.root@elwamui-milano.atl.sa.earthlink.net> The advice works only if the head had become mechanically misaligned, and you happened to turn the screw just the right amount to correct it. IF the NAAC is working perfectly, AND the tape travel is perfect. AND you play an azimuth alignment tape, the position of the azimuth pointer will then tell the story....centered on the mark and your adjustment is perfect. Note however that there are a number of variables you cannot have confidence in, and adjusting the head yourself may have added one more. I am not saying it is wrong to do this, as much as saying your alignment may not be correct. Does that make sense? Every alignment begins with references, tapes and gauges that are designed for this purpose. I'll share a behind the scenes insight with you. I often have trouble supporting some of the solutions posted as DIY repairs because they miss the true source of the problem, or "work around" a deeper problem. I do however attempt to balance advice so that harmless DIY solutions that get the decks in working condition receive my support, but any harmful DIY solution, such as filing the reel motor pulley, is advertized as such. I just cannot recommend tuning an azimuth screw without first confirming that head azimuth is incorrect, or at least having a method to check azimuth. With a Dragon, if you have confidence that tape path is OK, pull CN-5 as described earlier, and adjust the play head azimuth while monitoring the 15kHz bias test tone...at least that will get you closer than your method. tom brucker -----Original Message----- >From: Gene Ess >Sent: Apr 6, 2009 10:54 AM >To: "Tom Brucker, Nakdoc" , Talk about Nakamichi Cassette Decks >Subject: RE: [naktalk] Dragon with NAAC problems... skew? > >Tom, > >That is very interesting.

The audio sounds fantastic and I can not discern any performance loss because of this tweak.

The play head is sacred! With NAAC, any mechanical head azimuth adjustment will produce an opposite adjustment by the NAAC, however most "clicking" problems are caused by tape travel, torque, or skew issues, and not azimuth alignment. An azimuth alignment tape is one tool you MUST have before adjusting heads! > A check may be made by removing the Dragon's bottom cover and unplugging the 2 conductor shielded CN-5 connector on the NAAC board. First, find this connector. Second, power the Dragon ON and open the cassette holder. Confirm that the azimuth motor moves the azimuth pointer to the center position (note the black plastic ridges line up). Third, unplug CN-5. >Fourth, play a known good tape and listen in mono. If there are plenty of highs and no phase sounds, especially when switching your preamp between mono and stereo, then the play azimuth is correct, and the NAAC alignment is at fault. If you hear large phase problems and a loss of treble, then azimuth MAY be one part of a larger problem(s). > Many disable NAAC by unplugging CN-5(the indicators will still blink) until they can service their decks. >Dragon alignment is very tricky, second only to the 681ZX, and should not be attempted casually! > >tom brucker >-----Original Message----- >>From: Gene Ess >>Sent: Apr 4, 2009 12:50 PM >>To: Talk about Nakamichi Cassette Decks >>Subject: RE: [naktalk] Dragon with NAAC problems... skew? >> >>My Dragon did the same.

Hi Richard, Yes, the cleaner is used with the cassette. put three to four drops on the felt cleaner pads, put the cassette in the deck, press play, and run the cleaner for about twenty to thirty seconds. Replace pad when visibly soiled. Although this is the best of the cassette-style cleaners, I still prefer using cotton swabs and S-721H cleaner fluid on my deck.  I have found cleaner cassettes don't do as good a job as you can do by hand. This cleaner cassette is best used for decks that make accessing the heads and pinch roller difficult, especially automobile cassette players.

It was under a different name at the time, 1986 or so. It was stated on the package that this tape and cleaner was the only officially approved cleaner by Nakamichi Corp. for their cassette decks.  Eventually as time went on, to almost current date, guys like Kurt at US Recording, stated that this was the replacement for the formula I used years ago, that was the supposed best, and approved by Nakamichi as their own cleaner used by Nakamichi Repair in California.                  And yes, you do apply the cleaner to the Tape, then let the tape do its thing.  I along with Kermit, feel it was more for convience, especially for cassette players in Cars, where the average user doesn't know how to get to the heads, or even want to.              I was emailed along time ago, by an Authorized Technician for many Manufacturers, such as AKAI, Tandberg, Revox, Technics, Pioneer, etc...and was told to buy this to use specifically on my Pinch Rollers.  So, I did, after hearing much about it from Kurt at US Recording........I was not at all pleased with this product.  The reason it was recommended to me just for rollers, and not so much for heads, was it is not powerful enough to clean heads, especially on a reel to reel machine, that may accumulate more dirt on heads, or possibly sticky shed tapes.....but that it was safe for Rubber rollers.  I find that it evaporates way too fast, and doesn't clean even the pinch rollers as well as the old TEAC Rubber cleaner once did.  I still have some of this TEAC stuff left, luckily. Plus I have a Rubber Cleaner/Rejuvenator from the Reel Pro Sound Guys on the Internet.  They sell a great Maintenance Kit, with various cleaners for heads, rubber, and lubricants and cleaners for Pots...etc...their product seems to be almost as good as the TEAC Rubber Cleaner.  But I personally dont care the the American Recorder product.....maybe its ok, if the heads never come in contact with a bad tape, or anything that may come off an older tape and accumulate on the heads.   Ray ----- Original Message ----- From: naktalk-request at naks.com To: naktalk at naks.com Sent: Sunday, April 5, 2009 6:03:55 AM GMT -05:00 US/Canada Eastern Subject: Naktalk Digest, Vol 74, Issue 6 Send Naktalk mailing list submissions to         naktalk at naks.com To subscribe or unsubscribe via the World Wide Web, visit         http://www.naks.com/mailman/listinfo/naktalk or, via email, send a message with subject or body 'help' to         naktalk-request at naks.com You can reach the person managing the list at         naktalk-owner at naks.com When replying, please edit your Subject line so it is more specific than "Re: Contents of Naktalk digest..."

To: Message-ID: Content-Type: text/plain; charset="iso-8859-1" I bought this just to see if it would make anything easier. It comes with 1/2 oz. of their S-721H tape head cleaner, a cassette that has printed on it "C-911B Cassette Cleaner", and a special "dropper" cap for the S-721H cleaner.   This came with no instructions at all. I don't know if the cleaner is suppossed to be applied to the cassette, then the cassette inserted and played? Or, the cleaner used only without the cassette and the cassette used dry?   This came without instructions, and there are no instructions online.   Not a very well supported product, in my opinion, when it comes without instructions.   Anyways, anyone else try this product and know the correct application?   Thanks,   Rick -------------- next part -------------- An HTML attachment was scrubbed...

Cosmetically, it's just missing the button plates for Rec Mute and Reverse Play to be in an almost excellent condition. It looks like the bias section needs to have it's orange caps replaced, as the 400Hz, and especially the 15kHz alignment tone have many dropouts. Now that I've cleaned the transport (the pinch rollers were so dirty that they looked like they were made from bakelite, and W&F was very high), it sounds excellent, beating my CR-3 by a country mile in high-frequency response (sure, auto-azimuth probably has a lot to do with this). There's one main problem I don't really understand. On many tapes, the NAAC works normally, but on a couple of prerecorded tapes, the NAAC keeps trying to push the head so far it's clicking continuously. Sometimes, only one side of the tape is affected by the problem, and the NAAC circuit tries to push the head in the same direction even if I swap the tape manually and play it in reverse mode. Sometimes, both sides are affected, and no matter if I use reverse or forward playback and reverse the tape, the head is always pushed in the same direction when it happens.  Is the problem likely to be tape skew or misalignment? I can't see any physical damage on the tapes that have some problems. Oh, and on one tape, one side only plays correctly in reverse mode. Also, is the deck *supposed* to click when azimuth is sent to the extremes? Since there's a pot that monitors the azimuth position, shouldn't the deck limit the head position by itself? Last thing, when the heads are lowering, there's a loud squeak coming from the transport (probably not the cam belt IMO) Cheers, Antoine ------------------------------ Message: 8 Date: Sat, 4 Apr 2009 13:50:46 -0400 From: "Gene Ess" Subject: RE: [naktalk] Dragon with NAAC problems... skew? To: "Talk about Nakamichi Cassette Decks" Message-ID: Content-Type: text/plain;        charset="iso-8859-1" My Dragon did the same.  If the NAAC is always moving consistently to one side, you can adjust the PB Head azimuth to move the range of NAAC into target.  My Dragon after this slight tweak plays all tapes wonderfully and NAAC shows no issues at all. The fact that this happens on some tapes and not all makes me think it is the tapes. But I suppose a slight tape path misalignment can cause this as well.  This would be a much tougher fix.

To: Message-ID: Content-Type: text/plain; charset="iso-8859-1" I ordered the American Recorder Cassette Cleaner from their site and recieved it yesterday. I thought it looked intersting and worth a try...if it makes cleaning easier, then all the better.   It comes as a kit, which includes a cassette with some sort of tape loaded inside, a bottle of their S-721-H tape head/pinch roller cleaner (excellent stuff) and a "dropper" cap for the bottle of cleaner.   My problem is, it did not come with any instructions. I looked at thei online site, and none are to be found. I sent an email yesterday, but probably won't get an answer until Monday. Because of the special included "dropper" cap, I'm assuming that the cleaner is used with the cassette? But, maybe not? The only cassette type head cleaners I have ever seen where dry type.   I'm not going to use this until I get instructions... I know... I know.. not the typical "Manly" way of doing things   Has anyone here ever used this product, and if so, what were your thoughts about it? Also, what procedure was recommended?     Thanks,     Rick   -------------- next part -------------- An HTML attachment was scrubbed...

I've just fixed the cam squeal (NR-0040) without dismanting anything, I placed drops of oil with a screwdriver tip on the visible cam parts and the problem's gone.

I have encountered a probelm with my 505, I have never seen. Before I start the troubleshooting, I thought I should ask here, in case someone has come across this before. Very simple : Load a tape, play, and sound is fine for maybe 5 seconds, then starts to distort and fade out in both channels. Stop - play sequence will play the tape again for another 5 secs, to fade out again. Meters show the fade out too. I am suspecting some dual opamp, as this has started to happen at the same time in both channels. Any hints welcome. rgds, LP.

Once you repair your Dragon, please stick around! The end attaches beneath the head block along the bottom front of the deck mechanism. It is the azimuth adjustment drive cable. Remove the front panel to expose the mechanism. Align the tab with the slot in the azimuth adjust wedge, and install by gently clicking the 4 nylon tabs in place. tom brucker -----Original Message----- >From: hhtltd at juno.com >Sent: Apr 10, 2009 9:06 AM >To: naktalk at naks.com >Subject: [naktalk] Photo of Nak Dragon Interior > >I'm doing some home repair work on a Dragon with issues recently >purchased from a friend.

Please refer servicing to a qualified person as this is a tricky machine and you may end up doing more harm than good fixing it yourself. this deck will certainly need complete calibration.

The problem occurs internally when one wiper detatches from its nylon holder inside the control. If you are brave and careful, desolder the pot, clip the heads of the two rivets on the rear plate, and remove the control shaft C clip. Remove the white nylon holder and the detached wiper. The two wipers are mounted on opposite sides of the holder, so locate the tiny tabs, and epoxy the loose wiper in the correct spot. Do not bend any contacts on the wiper! Reassemble and epoxy the end plate to the rivets. I wonder if the MR1/2 BX 300 pitch control pot could be repaired using the same technique. tom brucker Hi Tech Service 2934 Nolensville Rd.

I doubt this is true, at least, during play. I can't remember *ever* hearing noise from the deck. Another myth is that the gear drive increases flutter. It's not clear how this can happen, since tape speed is not affected by the take up hub in a properly functioning transport. > ... that replaces the rubber idler, however it also requires regular > replacement every two years or so..." > > Does that means that S/N later than 8677 have not the equalization error?

It kept mudding up the recording, so I had to use a Sennheiser MD421 for the "low tom" and my faithful AKG D202E (bass cut switched in) for the "high tom." Nice! -- until the phasing problems cropped up. Had to build a phase shifter from scratch to clean up the drum tracks. Anyway, back to the point: yes, to my ears the flutter-and-wow of the gear mod is plainly discernible during casual listening. The CR7 without the gear mod is splendid, but those as for those with the gear mod I cannot stand to listen to solo violin or viola, massed strings, harpsichord, dobro, or piano. you're correct, It's because the flutter's period is higher in the spectrum. For my tastes, the gear mod is a good way to diminish an otherwise-wonderful recorder. A CR7 is one of the few analog cassettes on which I enjoy solo piano music.

Correct tape travel is (or should be) under sole control of the capstans. If takeup torque, capstan speed and pinch rollers pressure are all correct, what happens on the takeup side of the capstans has zero affect on tape travel. I understand what you are saying: that the jerky movement due to the gear teeth somehow affects tape movement past the head -- but this cannot happen if everything is adjusted to spec.

Of course, to each his own and each is entitled to his opinion. However, IM(Very)HO, your flutter comparison is invalid. Of course, a deck with a gear idler can have higher flutter than another deck that has a rubber idler -- just not necessarily due to the idlers. For a valid comparison, one should use the same deck, with the only difference being the idler. Since this is impractical, I suggested comparing a gear idler to no-idler on the same deck. Assuming a properly calibrated transport, this should produce identical flutter readings. And, oh, BTW, I, too, am a fan of piano music -- and have a bunch of piano solo tapes. FWIW, I don't hear flutter from any, even though my CR-7 has the gear mod. -- Ron Kermit Gray wrote: > Hi Tom, > > Oh dear, speaking of toms, I just finished a recording where the > musician designated one of his drums as the "high tom."

The only problem is that the gear, although excellent quality, does have a small amount of backlash, as is often the case with almost any gear or cog mechanism. The backlash along with the pitch of the teeth causes the increased flutter frequency. As in all things made, some gears are fabricated at different tolerances throughout the run, and so are prone to more backlash than others, this means it IS inevitable a gear of typical tolerances, such as those used in the CR7, have higher W&F. By the by, one reason that record cutting lathes, like the Scully or Neumann, are so costly is the extreme precision of the machining of the feed screw required to achieve low flutter-and-wow. If the gear in the CR7 was of the same fine tolerances it would cost thousands of dollars each. I've seen high-speed video of the gear mod in action, and there is no doubt of the backlash of the CR7 gear mod. -- Kermit Gray notarbene at kvglabs.com KVG Laboratories Equipment to Make Your Music Better 16371 Lake Point Drive Bonner Springs, KS 66012 USA Telephone: 913-422-0957 Skype ID: triodelicacy -------------- next part -------------- An HTML attachment was scrubbed...

Backlash only exists when a gear goes back and forth. When it rotates in the same direction, backlash is zero. But maybe you mean that as a driving tooth rotates, the driven gear speed is not constant? This, of course, is a function of the tooth curve. There is a (almost) constant speed tooth shape and I would be surprised if Nak engineers didn't use it. However, I am not a mechanical engineer and can't speak to the finer points of gear drive design. Luckily, this is not a problem. Even accepting that that the gear does not rotate at constant speed, this is immaterial, because tape movement is restricted by the capstan/pinch roller. As long as the pulling force of the takeup onanism's is not so strong as to pull the tape from the capstan/pinch roller grasp (as it is not in a correctly operating transport) tape speed is not affected by takeup force. > > I've seen high-speed video of the gear mod in action, and there is no > doubt of the backlash of the CR7 gear mod. I'll have to see it before I believe it. I have dealt with several servo designs and have never, ever, seen backlash where the driving gear continually rotates in the same direction. -- Ron > > -- Kermit Gray > notarbene at kvglabs.com > KVG Laboratories > Equipment to Make Your Music Better > 16371 Lake Point Drive > Bonner Springs, KS 66012 USA > Telephone: 913-422-0957 > Skype ID: triodelicacy > -------------- next part -------------- An HTML attachment was scrubbed...

I have no torque measuring tool (actually, thought about making one, but this project is on the back burner). As Richard has correctly observed, most decks (at least, those crossing my path) have badly maladjusted torque; usually, to high. I have found a procedure of arriving at a good approximation at the correct adjustment without benefit of a torque meter. I start by putting in an old C120 cassette (worn slip sheets represent worst case) and repeatedly play the last 30 seconds, again and again, reducing takeup torque from play to play, until takeup finally fails just before EOT. I verify that point by playing that same section several times. I then continue, minutely increasing torque very slightly each time, until takeup consistently works reliably to EOT. Once at this point, I simply add a touch (maybe 1/8 of a turn) to the adjustment pot (VR601, in many Nak models) and I'm done. Is this neat or what? :-) -- Ron Kermit Gray wrote: > Hi Richard, Ron, > > > On Apr 18, 2009, at 4:28 PM, RKern70055 at aol.com > wrote: > >> Ron: Take up torque has a real effect on tape movement.

Meeting spec for any quality piece of equipment is only the beginning. Spec's are the manufacturers way of stating the minimum performance possible from the equipment. Idler wheels do wear out in play mode as well as fast wind. If you look at the classic Nakamichi transports you will see clutch's inside each reel table and on the idler wheel assembly. These are designed to slip so the wear on the idler assembly is reduced. The slippage occurs when the tape stops at the end (in either fast wind or play) or when the take up reel is moving slowly. Put a tape in play mode and watch the take up reel. The back of the reel driven by the idler will move faster then the front of the reel that pulls the tape. This speed will vary depending on the size of the tape on the take up reel. The idler must run faster then the take up reel to ensure proper take up torque and smooth tape handling. This will cause some wear to the idler, but cant be avoided. Idlers also wear out due to temperature and age. Nakamichi's have a very fast auto shut off system, so wear is low compared to other makers decks. The only way to lesson wear in fast wind mode is to manually stop the deck just before the end of the tape. As to Wow & Flutter measurements, I stated earlier that I have measured lower wow & flutter after properly setting take up torque. I stand by this statement. You can choose to believe it or not.

I previously stated that on a correctly functioning deck,, takeup force does not affect flutter. When it does, there must be faults in the transport, that should be repaired until it no longer does. Incorrect torque is just one of these possibly faults. . As to your "there is no such thing as a perfectly functioning deck", a lot depends on your definition of 'perfect'. In my book, a 'perfect' deck is one that meets specs. Based on this definition, perfect decks do exist -- by the millions. Of all makes, including Nakamichi. Also, FYI, rubber idler tires get worn during FF and REW -- not during play. Thus, torque adjustment has no effect on tire longevity (except, just maybe, when carried to absurd extremes). -- Ron _RKern70055 at aol.com_ (mailto:RKern70055 at aol.com) wrote: Ron: Take up torque has a real effect on tape movement. It effects wow and flutter, can stretch or damage your tapes and can even throw the speed off. Why, because there is no such thing as a perfectly functioning deck. I have owned many new Nakamichi's and restored many old ones. In almost all of them the take up torque was too high. Why do you think idler wheels wear out so fast in Nakamichi's? The only way to minimize this problem is to set the take up torque with a torque tape. Adjust the reel motor take up torque in play mode (adjustment pot is on the power supply board for most Nakamichi's) to around 50-60 on the meter. This will decrease the wear on the reel motor idler wheel and your tapes. You may even hear a lower wow and flutter, I know I have.

Pacific Daylight Time, _ra.ah at verizon.net_ (mailto:ra.ah at verizon.net) writes: Tom, no offense, but tape movement in a properly functioning transport is not affected by take up reel movement . Correct tape travel is (or should be) under sole control of the capstans. If takeup torque, capstan speed and pinch rollers pressure are all correct, what happens on the takeup side of the capstans has zero affect on tape travel. I understand what you are saying: that the jerky movement due to the gear teeth somehow affects tape movement past the head -- but this cannot happen if everything is adjusted to spec. Try the following experiment: Measure flutter on a gear driven CR-7. Then hold the takeup hub and take another reading (quickly, before the transport stops). The flutter should be the same. If not, check takeup torque, capstan speed and pinch roller pressure and measure again. Bottom line... An increased flutter due to the gear is a fault, not a pre- ordained condition. -- Ron Tom Brucker, Nakdoc wrote: Ron, I claim to be able to hear gear mod flutter. IIRC kermit hears it too.

Earlier machines have two weaknesses: an equalization error (up to S/N 8677), and a short-lived rubber idler (up to roughly S/N 10500). I am not sure how this 'complicates matters' is it can be fully explained in a line and a half of clear cut text. . Some audiophiles actually prefer the rubber idler for listening because it is quieter than the gear drive ... I doubt this is true, at least, during play. I can't remember ever hearing noise from the deck. Another myth is that the gear drive increases flutter. It's not clear how this can happen, since tape speed is not affected by the take up hub in a properly functioning transport. ... that replaces the rubber idler, however it also requires regular replacement every two years or so..." Does that means that S/N later than 8677 have not the equalization error? Yes.

The only problem is that the gear, although excellent quality, does have a small amount of backlash, as is often the case with almost any gear or cog mechanism. The backlash along with the pitch of the teeth causes the increased flutter frequency. As in all things made, some gears are fabricated at different tolerances throughout the run, and so are prone to more backlash than others, this means it IS inevitable a gear of typical tolerances, such as those used in the CR7, have higher W&F. By the by, one reason that record cutting lathes, like the Scully or Neumann, are so costly is the extreme precision of the machining of the feed screw required to achieve low flutter-and-wow. If the gear in the CR7 was of the same fine tolerances it would cost thousands of dollars each. Backlash only exists when a gear goes back and forth. When it rotates in the same direction, backlash is zero. But maybe you mean that as a driving tooth rotates, the driven gear speed is not constant? This, of course, is a function of the tooth curve. There is a (almost) constant speed tooth shape and I would be surprised if Nak engineers didn't use it. However, I am not a mechanical engineer and can't speak to the finer points of gear drive design. Luckily, this is not a problem. Even accepting that that the gear does not rotate at constant speed, this is immaterial, because tape movement is restricted by the capstan/pinch roller. As long as the pulling force of the takeup onanism's is not so strong as to pull the tape from the capstan/pinch roller grasp (as it is not in a correctly operating transport) tape speed is not affected by takeup force. I've seen high-speed video of the gear mod in action, and there is no doubt of the backlash of the CR7 gear mod. I'll have to see it before I believe it. I have dealt with several servo designs and have never, ever, seen backlash where the driving gear continually rotates in the same direction. -- Ron -- Kermit Gray _notarbene at kvglabs.com_ (mailto:notarbene at kvglabs.com) KVG Laboratories Equipment to Make Your Music Better 16371 Lake Point Drive Bonner Springs, KS 66012 USA Telephone: 913-422-0957 Skype ID: triodelicacy ========---------------------------------------------------------========= Also check out the wiki! http://www.naks.com/wiki ========---------------------------------------------------------========= Naktalk at naks.com mailinglist Maintain your account here: http://www.naks.com/mailman/listinfo/naktalk ========---------------------------------------------------------========= **************A Good Credit Score is 700 or Above.

Again, thanks for the lesson, but I'm afraid you do not understand how Sankyo transports work. There is no question some slip mechanism is required to drive takeup hubs. You outlined how this can be accomplished mechanically. The problem with that (very widely used) approach scheme is the high wear of the felt slip-clutch and the uneven takeup torque. So, high end deck do it differently. In the Sankyo transport, the slip is *electrical*. There is *no* mechanical slippage whatsoever. The reel motor is underdriven by a very low voltage (less than 4V), producing just enough torque to overcome cassette hub friction and maintain slight tape tension. Even completely stopping the takeup hub. does not cause idler slippage (the motor simply stops) and therefore, does not cause idler wear, unless, as you so wisely pointed out, torque is misadjusted too high. FF/REW operation is designed to avoid idler slippage, as well. However. the motor is driven by close to full voltage (over 9V), resulting in high torque. Add to that the kinetic energy of the fast spinning hubs and the small idler to pulley contact area -- and slippage occurs every time the FF or REW starts or stops. > > Idlers also wear out due to temperature and age. > Nakamichi's have a very fast auto shut off system, so wear is low > compared to other makers decks. > The only way to lesson wear in fast wind mode is to manually stop the > deck just before the end of the tape. > > As to Wow & Flutter measurements, I stated earlier that I have > measured lower wow & flutter after > properly setting take up torque. I stand by this statement. You can > choose to believe it or not. I guess I misunderstood you. I disagreed with the claim that the gear idler increased flutter. I fully agree that when the torque setting is too high (among several other possible faults) , the takeup force could overcome the capstan-to-tape-to pinch roller friction and increase flutter. -- Ron > > Richard Kern > > > In a message dated 4/19/2009 2:37:34 P.M.

I start by putting in an old C120 cassette (worn slip sheets represent worst case) and repeatedly play the last 30 seconds, again and again, reducing takeup torque from play to play, until takeup finally fails just before EOT. I verify that point by playing that same section several times. I then continue, minutely increasing torque very slightly each time, until takeup consistently works reliably to EOT.

The only way to minimize this problem is to set the take up torque with a torque tape. Adjust the reel motor take up torque in play mode (adjustment pot is on the power supply board for most Nakamichi's) to around 50-60 on the meter. This will decrease the wear on the reel motor idler wheel and your tapes. You may even hear a lower wow and flutter, I know I have.

I have no torque measuring tool (actually, thought about making one, but this project is on the back burner). As Richard has correctly observed, most decks (at least, those crossing my path) have badly maladjusted torque; usually, to high. I have found a procedure of arriving at a good approximation at the correct adjustment without benefit of a torque meter. I start by putting in an old C120 cassette (worn slip sheets represent worst case) and repeatedly play the last 30 seconds, again and again, reducing takeup torque from play to play, until takeup finally fails just before EOT. I verify that point by playing that same section several times. I then continue, minutely increasing torque very slightly each time, until takeup consistently works reliably to EOT. Once at this point, I simply add a touch (maybe 1/8 of a turn) to the adjustment pot (VR601, in many Nak models) and I'm done.

This is not as hard to do as you may think since manufacturers spec is the minimum guaranteed performance as stated in the owners manual. And most manufactures meet and exceed their stated specs. Sankyo idler wheels don't wear out? Ron, where have you been! If I had a dollar for every idler wheel I have replaced over the last 30 years, I could retire. Compared to the cl assic Nakamichi drives the Sankyo drive is far more unreliable, specially when it comes to take up torque problems. The reel motor fails or the idler slips causing the set to shut off inadvertently. I hate to break this to you Ron, but I do know how the Sankyo drives work. I have been repairing them for almost 25 years. Richard Kern In a message dated 4/20/2009 1:24:02 P.M. Pacific Daylight Time, ra.ah at verizon.net writes: _RKern70055 at aol.com_ (mailto:RKern70055 at aol.com) wrote: Ron: Meeting spec may be your definition of perfect, but is not mine. Meeting spec for any quality piece of equipment is only the beginning. In that case, your perfect deck indeed does not exist. It seems your definition of a perfect deck is one that meets your expectations, regardless of what the manufacturer says (or designed it for). After all, nothing is impossible if someone else has to do it. Spec's are the manufacturers way of stating the minimum performance possible from the equipment. And it it does, it's as perfect as it can get. Idler wheels do wear out in play mode as well as fast wind. Not in a correctly functioning Sankyo transport, they don't. If you look at the classic Nakamichi transports you will see clutch's inside each reel table and on the idler wheel assembly. These are designed to slip so the wear on the idler assembly is reduced. The slippage occurs when the tape stops at the end (in either fast wind or play) or when the take up reel is moving slowly. Yea, will all know how tape decks work. Put a tape in play mode and watch the take up reel. The back of the reel driven by the idler will move faster then the front of the reel that pulls the tape. This speed will vary depending on the size of the tape on the take up reel. The idler must run faster then the take up reel to ensure proper take up torque and smooth tape handling. This will cause some wear to the idler, but cant be avoided. Again, thanks for the lesson, but I'm afraid you do not understand how Sankyo transports work. There is no question some slip mechanism is required to drive takeup hubs. You outlined how this can be accomplished mechanically. The problem with that (very widely used) approach scheme is the high wear of the felt slip-clutch and the uneven takeup torque. So, high end deck do it differently. In the Sankyo transport, the slip is electrical. There is no mechanical slippage whatsoever. The reel motor is underdriven by a very low voltage (less than 4V), producing just enough torque to overcome cassette hub friction and maintain slight tape tension. Even completely stopping the takeup hub. does not cause idler slippage (the motor simply stops) and therefore, does not cause idler wear, unless, as you so wisely pointed out, torque is misadjusted too high. FF/REW operation is designed to avoid idler slippage, as well. However. the motor is driven by close to full voltage (over 9V), resulting in high torque. Add to that the kinetic energy of the fast spinning hubs and the small idler to pulley contact area -- and slippage occurs every time the FF or REW starts or stops. Idlers also wear out due to temperature and age. Nakamichi's have a very fast auto shut off system, so wear is low compared to other makers decks. The only way to lesson wear in fast wind mode is to manually stop the deck just before the end of the tape. As to Wow & Flutter measurements, I stated earlier that I have measured lower wow & flutter after properly setting take up torque. I stand by this statement. You can choose to believe it or not. I guess I misunderstood you. I disagreed with the claim that the gear idler increased flutter. I fully agree that when the torque setting is too high (among several other possible faults) , the takeup force could overcome the capstan-to-tape-to pinch roller friction and increase flutter. -- Ron Richard Kern In a message dated 4/19/2009 2:37:34 P.M. Pacific Daylight Time, _ra.ah at verizon.net_ (mailto:ra.ah at verizon.net) writes: Richard, takeup torque has any effect on flutter only when incorrectly set. I previously stated that on a correctly functioning deck,, takeup force does not affect flutter. When it does, there must be faults in the transport, that should be repaired until it no longer does. Incorrect torque is just one of these possibly faults. . As to your "there is no such thing as a perfectly functioning deck", a lot depends on your definition of 'perfect'. In my book, a 'perfect' deck is one that meets specs. Based on this definition, perfect decks do exist -- by the millions. Of all makes, including Nakamichi. Also, FYI, rubber idler tires get worn during FF and REW -- not during play. Thus, torque adjustment has no effect on tire longevity (except, just maybe, when carried to absurd extremes). -- Ron _RKern70055 at aol.com_ (mailto:RKern70055 at aol.com) wrote: Ron: Take up torque has a real effect on tape movement.

Correct tape travel is (or should be) under sole control of the capstans. If takeup torque, capstan speed and pinch rollers pressure are all correct, what happens on the takeup side of the capstans has zero affect on tape travel. I understand what you are saying: that the jerky movement due to the gear teeth somehow affects tape movement past the head -- but this cannot happen if everything is adjusted to spec. Try the following experiment: Measure flutter on a gear driven CR-7. Then hold the takeup hub and take another reading (quickly, before the transport stops). The flutter should be the same. If not, check takeup torque, capstan speed and pinch roller pressure and measure again. Bottom line... An increased flutter due to the gear is a fault, not a pre- ordained condition. -- Ron Tom Brucker, Nakdoc wrote: Ron, I claim to be able to hear gear mod flutter. IIRC kermit hears it too.

I am not sure how this 'complicates matters' is it can be fully explained in a line and a half of clear cut text. . Some audiophiles actually prefer the rubber idler for listening because it is quieter than the gear drive ... I doubt this is true, at least, during play. I can't remember ever hearing noise from the deck. Another myth is that the gear drive increases flutter. It's not clear how this can happen, since tape speed is not affected by the take up hub in a properly functioning transport. ... that replaces the rubber idler, however it also requires regular replacement every two years or so..." Does that means that S/N later than 8677 have not the equalization error? Yes.

In a dual capstan deck take up and hold back tensions are theoretically isolated, so it shouldn't matter what the torque is. We've seen that there must be enough torque to wind the tape, but not so much torque that the tape is pulled through the pinch roller contact area. Richard's comments are correct, that when pinch rollers are bit dirty the tape may behave differently than with a clean deck. My opinion is that 40 gm/cm will outperform 50 gm/cm in real world conditions. I also like lower torque for T-110 tapes. 50gm/cm works fine with a clean deck, but I can't imagine any benefit higher torque might provide. Any discussion? Single capstan decks by contrast must have correct hold back tension and smooth take up torque to operate at all. I would almost say a dual capstan deck is 3 times better than a single in flutter performance. Nakamichi was (again my opinion) the only brand that individually aligned each deck. Typical decks use slip clutches in the reel table to establish torque, so the force is adjusted mechanically in 3 or 4 steps, if it is adjustable at all! I think Nakamichi knew what was required to reduce W/F below 0.10 %....a DC servo motor driving an idler. Sony,Revox, Tandberg, and Pioneer made an attempts to design an excellent transport using direct drive reel motors with fine results, but also at increased cost and complexity. Given that the Sankyo decks were "naks for the masses" cost was a critical factor. So to finish this answer, often experience leads to special tweaks, a process that is understood well in the audio community. tom brucker -----Original Message----- >From: boitrel >Sent: Apr 20, 2009 4:40 AM >To: Talk about Nakamichi Cassette Decks >Subject: Re: [naktalk] cr7 Eq mod > >Tom, Richard, Ron > >Thank's a lot for this very instructive discussion about torque >measurement correlated or not to W&F specifs. >But as a neophyte, one question directly comes to my mind: why hell, >does the take-up torque seem to be tuned (from factory?) generally too >high?

In a dual capstan deck take up and hold back tensions are theoretically isolated, so it shouldn't matter what the torque is. We've seen that there must be enough torque to wind the tape, but not so much torque that the tape is pulled through the pinch roller contact area. Richard's comments are correct, that when pinch rollers are bit dirty the tape may behave differently than with a clean deck. My opinion is that 40 gm/cm will outperform 50 gm/cm in real world conditions. I also like lower torque for T-110 tapes. 50gm/cm works fine with a clean deck, but I can't imagine any benefit higher torque might provide.  Any discussion?    Single capstan decks by contrast must have correct hold back tension and smooth take up torque to operate at all.

Fitted new rubber and the deck idles nicely - but the pinch roller pivots are gummed up so tape travel is poor.  Transport coming back out - but not tonight.

Initially there was no output with this project deck but replacement of the failed stop lamp resolved the mute condition. A 3mm 12V 30mA bulb was a perfect solution.  Also replaced the play lamp with the same and the counter and cassette well lamps with 3 mm 12V 40mA which were also a good match. Transport strip down is next as the torque is insufficient to drive a tape.  The heads struggle to fully engage.  FF / RW is a bit slow.  Transport is very dirty. Meters are flashing a bit so probably a 4700pF cap within the meter module, will have a look once the transport is back together and runs properly.

After pressing Pause during play, is one of the Play LEDs supposed to remain lit? If so, your circuit will keep driving the reel motor when in pause, which may be not what you want. The play button activates TTL low that remains high low cleared by another function (pause FF ect) then goes back high. Second, you may wish to power the V+ and VL pins off +12V and +5V respectively (V- at ground or -12V). I will look at that Third, I am not sure why you need the 2N3609 transistor. Why not drive the DG419 directly from the Lplay line and swap the switch sections? The 2n3609 is a low pass simple logicfilter that passes 5v to the DG419 only on the low from the play back latch circui (normally rides high)t. Granted, I haven't gone over the DG419 data and app notes, so I may be wrong. These are just random questions that popped up as I was looking at your circuit.

Reference voltage is 0 <> .05 % does not change in play mode. (Should be -4 Volts in play at TP1) FF and RW function properly at voltage so issue is not motor control transistors.

Before I go to the extreme of replacing a 42 pin micro processor that is unit specific, "LM6402A-052" to Nakamichi (it also comes in LX-3's and ZX-7's) I was hoping that there is a different solution. Maybe a work around that some one else has come up with maybe I missed something. I fear that surgery of this type might be a 2 day trip into hell. Any suggestions?

You are forgetting some simple truths. 1. Forget the fact that I have been servicing these decks for 25 plus years and see the high rate at which they fail, compared to the classic Nak drives. Sankyo idler wheels wear out every two to three years on average, vs. the classic Nak drives that that last 5 to 10 tines longer. 2. Forget the fact that 95% of the time most people play or record with their decks and do not fast wind their tapes. If Sankyo idlers never wear out in play/record mode this would make them the best drives ever made and they would rarely need service. 3. Next you will tell use that Nak owners with the Sankyo drives are more prone to use fast wind rather then play mode. 4. The truth is Sankyo drives fail not just from use, but due to their poor design. Period, end of story. Richard Kern In a message dated 4/21/2009 7:54:24 A.M.

If I had a dollar for every idler wheel I have replaced over the last 30 years, I could retire. Nobody said Sankyo tires do not wear out., least of all, me. I said they do not wear out during play.

Claiming I said something obviously incorrect, then shooting it down, doesn't cut it. Compared to the classic Nakamichi drives the Sankyo drive is far more unreliable, specially when it comes to take up torque problems. The reel motor fails or the idler slips causing the set to shut off inadvertently. I hate to break this to you Ron, but I do know how the Sankyo drives work.

If you look at the classic Nakamichi transports you will see clutch's inside each reel table and on the idler wheel assembly. These are designed to slip so the wear on the idler assembly is reduced. The slippage occurs when the tape stops at the end (in either fast wind or play) or when the take up reel is moving slowly. Yea, will all know how tape decks work. Put a tape in play mode and watch the take up reel. The back of the reel driven by the idler will move faster then the front of the reel that pulls the tape. This speed will vary depending on the size of the tape on the take up reel. The idler must run faster then the take up reel to ensure proper take up torque and smooth tape handling. This will cause some wear to the idler, but cant be avoided. Again, thanks for the lesson, but I'm afraid you do not understand how Sankyo transports work. There is no question some slip mechanism is required to drive takeup hubs. You outlined how this can be accomplished mechanically. The problem with that (very widely used) approach scheme is the high wear of the felt slip-clutch and the uneven takeup torque. So, high end deck do it differently. In the Sankyo transport, the slip is electrical. There is no mechanical slippage whatsoever. The reel motor is underdriven by a very low voltage (less than 4V), producing just enough torque to overcome cassette hub friction and maintain slight tape tension. Even completely stopping the takeup hub. does not cause idler slippage (the motor simply stops) and therefore, does not cause idler wear, unless, as you so wisely pointed out, torque is misadjusted too high. FF/REW operation is designed to avoid idler slippage, as well. However. the motor is driven by close to full voltage (over 9V), resulting in high torque. Add to that the kinetic energy of the fast spinning hubs and the small idler to pulley contact area -- and slippage occurs every time the FF or REW starts or stops. Idlers also wear out due to temperature and age. Nakamichi's have a very fast auto shut off system, so wear is low compared to other makers decks. The only way to lesson wear in fast wind mode is to manually stop the deck just before the end of the tape. As to Wow & Flutter measurements, I stated earlier that I have measured lower wow & flutter after properly setting take up torque. I stand by this statement. You can choose to believe it or not. I guess I misunderstood you. I disagreed with the claim that the gear idler increased flutter. I fully agree that when the torque setting is too high (among several other possible faults) , the takeup force could overcome the capstan-to-tape-to pinch roller friction and increase flutter. -- Ron Richard Kern In a message dated 4/19/2009 2:37:34 P.M.

The only way to minimize this problem is to set the take up torque with a torque tape. Adjust the reel motor take up torque in play mode (adjustment pot is on the power supply board for most Nakamichi's) to around 50-60 on the meter.

On other gear (non-Nakamichi), I have swapped out many a 741/1458/etc. with NE5534s and had to add bypassing to prevent oscillation. I agree, the resulting changes were a dramatic increase in overall sound quality. In the very near future, I may end up replacing the 4558 chips in a PA system head for a friend with something new/improved as this person really likes this aging PA head.

Sankyo idler wheels wear out every two to three years on average, vs. the classic Nak drives that that last 5 to 10 tines longer. 2. Forget the fact that 95% of the time most people play or record with their decks and do not fast wind their tapes. If Sankyo idlers never wear out in play/record mode this would make them the best drives ever made and they would rarely need service. 3. Next you will tell use that Nak owners with the Sankyo drives are more prone to use fast wind rather then play mode. 4.

If I had a dollar for every idler wheel I have replaced over the last 30 years, I could retire. Nobody said Sankyo tires do not wear out., least of all, me. I said they do not wear out during play. I also said they do wear out, all the time, during FF/REW, even though they were not meant to. I even explained why. You know, we are trying to carry on an intelligent conversation here. Claiming I said something obviously incorrect, then shooting it down, doesn't cut it. Compared to the classic Nakamichi drives the Sankyo drive is far more unreliable, specially when it comes to take up torque problems. The reel motor fails or the idler slips causing the set to shut off inadvertently. I hate to break this to you Ron, but I do know how the Sankyo drives work. I have been repairing them for almost 25 years. Gee, with all the talk about mechanical slip clutches, you had me fooled. And, BTW, I doubt you could break anything to me.

A number of Nakamichis, especially the higher end models do not have a dry and gritty sound as far as I have listened to them in stock condition. The only dry and gritty model that disappointed me is the DR10. On the contrary, the ZXL series as a very open and sweet sound while providing an unbelievably large sound-stage. This may not be so apparent on some systems as the final performance is very much dependent on the rest of the system, room, set-up etc. The Dragon is another deck that has a very nice sound and does not exhibit any of the traditional nasty sound op-amps have been credited with. The 680, 670, 660, 5 series decks all have a wonderful sound - in fact I love the 670 for it's laid back and warm sound! I am quoting these decks as they use the RC4885 op-amps - and these were the first generation of commercial op-amps ever made! I do not mind the tweaking but I have been suspecting for sometime that the limitations have more to do with the tapes (and their condition after years of storage) more then the electronics.

After pressing Pause during play, is one of the Play LEDs supposed to remain lit? If so, your circuit will keep driving the reel motor when in pause, which may be not what you want. The play button activates TTL low that remains high low cleared by another function (pause FF ect) then goes back high. Second, you may wish to power the V+ and VL pins off +12V and +5V respectively (V- at ground or -12V). I will look at that Third, I am not sure why you need the 2N3609 transistor.

VR601 tested good. Gate on IC605 looks to be correct in all functions save play. Problem remains. Logic tests. Pins on IC601 test fine on input side. Read Correctly Pins on IC601 on output side FF and Rewind are as per POO manual BUT pin 28 (Play Control) has no status change in play mode remains low. Play mode reads as follows. Pin 26 – Rewind – L Pin 27 – Fast Forward – L Pin 28 – Play – L *** according to the POO Manual this should go OPEN triggering Q604 *** Now for my next step …… I have seen on the net that this problem is not unique to my Dragon; however I have found no solutions posted. Before I go to the extreme of replacing a 42 pin micro processor that is unit specific, “LM6402A-052” to Nakamichi (it also comes in LX-3’s and ZX-7’s) I was hoping that there is a different solution. Maybe a work around that some one else has come up with maybe I missed something. I fear that surgery of this type might be a 2 day trip into hell. Any suggestions? PS Thanks for the POO manual this would be impossible to even try to fix with out it.

Several times some excessive tweaking leads me to the audio dead-end and I had to start from some previous point moving in another direction. And the last but not least - thorough tweaking could easily double or even triple the price you paid for the original machine. Think for yourself if all this is worth your money and effort. >From my modest personal experience the most profound difference I got was after replacing the most critical lytics in the signal path and power supply for non-polar Black Gates (E-Cap) and introducing Infineon carborundum diods (better than HEXFREDs) into the power supply.

On other gear (non-Nakamichi), I have swapped out many a 741/1458/etc. with NE5534s and had to add bypassing to prevent oscillation. I agree, the resulting changes were a dramatic increase in overall sound quality. In the very near future, I may end up replacing the 4558 chips in a PA system head for a friend with something new/improved as this person really likes this aging PA head. (made by a Japanese company called TOA) Would love to hear more about what you have done with Nak decks.

Message-ID: BG: In the context of a normal Mid Fi system your observations about the various Nakamichi's stock sound is correct. When compared to modern Hi End equipment the Nakamichi's show their age. The stock OP Amps used in the older Nakamichi's and even the Dragon and CR-7 are by today's standards CRAP. I just replaced the OP Amps in my Dragon with BB OPA-2604 chips and the sound is excellent. As clean and clear as any modern SACD or CD player. The total cost to replace 9 IC's in the Dragon was $36. One of the cheapest upgrades I have ever done. Richard Kern In a message dated 4/23/2009 12:20:12 A.M.

In-Reply-To: References: Message-ID: <49F070BE.8070606@verizon.net> I wonder what Nak model you find to have a "dry, gritty, canned sound". I have carefully listened to many, many Naks and can't recall any of them with that kind of sound. Replacing op-amps has been discussed to death here. Years ago, I reported here on an informal listening test I conducted on my CR-7. No recording was involved, we simply compared high quality CDs played directly, with the same CDs, played through the source monitoring of the CR-7. In this ABX test, each selection was played twice (with or without the CR-7 monitoring), or twice straight through or twice with the CR-7 monitoring. Listeners were asked whether they heard any difference. Turned out that injecting the CR-7 monitoring circuitry in the signal path was *not discernible* by any listener (including a 13 years old boy and several young women). My conclusion was that there was no advantage to upgrading op-amps, since presence of several in the signal path made no audible difference. BTW, there is nothing wrong with the OPA2604, though I personally prefer the OPA2134 (compare specs or just listen to it and you'll see why -- it sounds very pure and clean). In very low level applications. I have found the extreme low noise of the ?PC4570 to be an advantage. -- Ron RKern70055 at aol.com wrote: > I have been replacing the stock audio IC chips in my Nakamichi > decks for years now and I was > wondering if anyone else has tried this.

After trying all I could to get the best sound out of a stock DR10, I next went into making mechanical and electronics. It did make a certain amount of difference but then, when I revisited my 670ZX waiting patiently by the sides, I started spending time listening and less tinkering.

There's certainly a big difference in sound, even though my ZXL is not as it should be. Still the DR10 is capable of good sound with tapes that suit. But I've often wondered what could be done to improve the DR10 - what would you, or anyone else, suggest?

To: naktalk at naks.com Hi Richard, There was a discussion on this some time ago here on Naktalk. A number of Nakamichis, especially the higher end models do not have a dry and gritty sound as far as I have listened to them in stock condition. The only dry and gritty model that disappointed me is the DR10. On the contrary, the ZXL series as a very open and sweet sound while providing an unbelievably large sound-stage. This may not be so apparent on some systems as the final performance is very much dependent on the rest of the system, room, set-up etc. The Dragon is another deck that has a very nice sound and does not exhibit any of the traditional nasty sound op-amps have been credited with. The 680, 670, 660, 5 series decks all have a wonderful sound - in fact I love the 670 for it's laid back and warm sound! I am quoting these decks as they use the RC4885 op-amps - and these were the first generation of commercial op-amps ever made! I do not mind the tweaking but I have been suspecting for sometime that the limitations have more to do with the tapes (and their condition after years of storage) more then the electronics.

Message-ID: Ron: When comparing Nakamichi decks in a normal Mid Fi system you are correct. The Nakamichi's sound fine in stock form, but the better your stereo system gets, the more you will hear the differences. Also if you really want to have some fun, compare the Naks to a good reel to reel deck. I recently compared a stock 682ZX to a stock Teac X-1000R reel to reel. Using the same CD's, audio cables and record levels as reference. Being careful to not overdrive either deck. I was checking for sound quality and not dynamics.

Just for the record, the system I ran the listening test on (and still.using today) consists of an Integra Research RDC-7.1, Aragon 8008 power amplifier (2 channels) and Aerial Acoustics 10T speakers. This may be considered a budget system by some, but still, is way above average (the 10Ts were Stereophile's 1996 Speaker of the year. The Aragon is one of their reviewers (I forget who) reference . My view is that the limiting factor (at least, for me) are the recordings, not the op-amps in the CR-7. > Also if you really want to have some fun, compare the Naks > to a good reel to reel deck. Actually, I owned several r-t-r decks before my first cassette deck (Nak 700.-- tells you how long ago this was). My favorites were ReVox and Grundig. I have neither the space nor the inclination to go back, so auditioning one will be an exercise in futility... -- Ron > > I recently compared a stock 682ZX to a stock Teac X-1000R reel to reel. > Using the same CD's, audio cables and record levels as reference. > Being careful to not overdrive either deck.

Oh come off it. What's "crap" is hyperbolic writing like that. The JRC- branded ICs used by Nakamichi are still excellent sound, even by today's standards; it's just as different sound than Burr-Brown or Analog Devices. Design technique is more important than the specific opamp; Nakamichi worked wonders with the chips they chose. Although I will admit I gave up finding an opamp I personally enjoyed, so I now make my own opamps from my own design. Alas, they aren't pin-compatible with those Nakamichi used, otherwise I'd sell them as upgrades. Maybe next year as economies-of-scale kick in. -- Kermit Gray notarbene at kvglabs.com KVG Laboratories Equipment to Make Your Music Better 16371 Lake Point Drive Bonner Springs, KS 66012 USA Telephone: 913-422-0957 Skype ID: triodelicacy -------------- next part -------------- An HTML attachment was scrubbed...

Message-ID: George: No offense, but 99 percent of the people in the world who own stereo's, own a mid-fi system. Audio experts have said for years that high end audio is only one percent of the total audio equipment production. Don't get me wrong, I like Nakamichi's. I always have and I always will. BUT: I do see a very disturbing trend in our society today and it is the foolish notion that nothing can be improved on. That the engineers that made the equipment 30 or 40 years ago are somehow Gods. That their designs are sacrosanct and cant be touched. You cant possibly improve on their design, so why even try. That to be happy today, you must settle for less. To strive for something better is evil and smacks of wasteful consumerism. We all know Hi End Audio is just for rich idiots with money to burn. Mid-fi sounds just as good and costs a lot less. Happily I have never subscribed to this moronic philosophy. With very few exceptions, you get what you pay for. As to your points, I can only tell you what I heard in my system. As we know Hi End systems vary greatly in sound quality depending on the equipment used and what it is matched with. I have heard $10,000 systems that sound better then $100,000 systems. I have also heard $100,000 systems to die for. A lot depends on the component matching, your room and your cabling.

Message-ID: Kermit: Come on now you know better then this. There has been mountains of literature in the engineering and audio community written on the pathetic sound of late 1970's and early 1980's IC's. Nakamichi did not use the best IC's even for the time, but considering the price point of their products they can be forgiven for it. Simply stated, 30 years have passed and there is no comparison to today's IC's. The real fallacy of your argument can easily be exposed. All one has to do is mount an IC socket in the deck and swap out the stock IC. You can then try as many new chips as you wish and if you don't like any of them, you can put the original IC back in.

The JRC-branded ICs used by Nakamichi are still excellent sound, even by today's standards; it's just as different sound than Burr-Brown or Analog Devices. Design technique is more important than the specific opamp; Nakamichi worked wonders with the chips they chose. Although I will admit I gave up finding an opamp I personally enjoyed, so I now make my own opamps from my own design. Alas, they aren't pin-compatible with those Nakamichi used, otherwise I'd sell them as upgrades.

The Kondo pre-amp is really beautiful sounding and have become really precious now that Kondo-san is no more. As for the comparison of the 1000ZXL with the Teac, I would suggest using normal Type I tape with DBX for better results. I am getting slightly better dynamics off my X1000R with Maxell UDXL tape compared to my 1000ZXL running on That's MRXP tape. EE type, I feel, does not really live up to its hype.

And before you even mention Mid Fi again: Wilson Audio Alexandria X2, Kondo Audio Note M-1000 Mk II, Kondo Audio Note Gakuon II, Valhalla Odin cabling, PS Audio power plants, Kuzma Stabi XL with Airline arm and Koetsu Blue Onyx Platinum, the full 4-piece dCS Scarlatti setup.

In-Reply-To: Message-ID: <951339.44076.qm@web30201.mail.mud.yahoo.com> One right thing that Teac did was to keep spares for all their old equipment, which is something rare for a Japanese manufacturer. Perhaps that is why they are perhaps the last few brands out there that has survived. I have coveted the X2000R for years and got my chance with one briefly. Perhaps that flirtation caused memories that still lingers... The beauty about semi pro and professional reel to reels is that their transports are quite straightforward and replacement can even be machined out. The domestic ones are different - inside lingers plastic parts and some complicated mechanisms that can render them useless once broken. Akai's GX747 comes to my mind when it comes to plastic parts and nice but not very long-living mechanism. What I like about the classic Nak mechanism is that even the details of the design has been so well thought out, that if one was properly services and taken care of, it can last for a long long time. The newer decks...... :) Rgds RKern70055 at aol.com wrote: Bala: You are correct that there are better reel to reels out there then my Teac, however the one I have is so close to New Old Stock, I cant believe it. The heads, guides, tension arms, capstan's, motors etc. have no wear. The caps were not dried up. Yes, I do know all about reel to reels having been an audio tech for 30 plus years. What keeps me away from the brands you mentioned is the lack of parts in the states. Europe may have a good supply of parts but not America. Heck, getting Nakamichi parts is a bitch these days.

Audio experts have said for years that high end audio is only one percent of the total audio equipment production. Don't get me wrong, I like Nakamichi's. I always have and I always will. BUT: I do see a very disturbing trend in our society today and it is the foolish notion that nothing can be improved on. That the engineers that made the equipment 30 or 40 years ago are somehow Gods. That their designs are sacrosanct and cant be touched. You cant possibly improve on their design, so why even try. That to be happy today, you must settle for less. To strive for something better is evil and smacks of wasteful consumerism. We all know Hi End Audio is just for rich idiots with money to burn. Mid-fi sounds just as good and costs a lot less. Happily I have never subscribed to this moronic philosophy. With very few exceptions, you get what you pay for. As to your points, I can only tell you what I heard in my system. As we know Hi End systems vary greatly in sound quality depending on the equipment used and what it is matched with. I have heard $10,000 systems that sound better then $100,000 systems. I have also heard $100,000 systems to die for. A lot depends on the component matching, your room and your cabling.

The Nakamichi's sound fine in stock form, but the better your stereo system gets, the more you will hear the differences. Also if you really want to have some fun, compare the Naks to a good reel to reel deck. I recently compared a stock 682ZX to a stock Teac X-1000R reel to reel. Using the same CD's, audio cables and record levels as reference. Being careful to not overdrive either deck. I was checking for sound quality and not dynamics. The Teac made the Nakamichi sound canned, compressed and two dimensional. And no, I was not recording too high for the Nak to handle the levels. I was also using the best Maxell matel tapes in the Nak. The Teac used the poor (by comparison) Maxell UD tape. Richard Kern In a message dated 4/23/2009 7:07:44 A.M.

I have carefully listened to many, many Naks and can't recall any of them with that kind of sound. Replacing op-amps has been discussed to death here. Years ago, I reported here on an informal listening test I conducted on my CR-7. No recording was involved, we simply compared high quality CDs played directly, with the same CDs, played through the source monitoring of the CR-7. In this ABX test, each selection was played twice (with or without the CR-7 monitoring), or twice straight through or twice with the CR-7 monitoring. Listeners were asked whether they heard any difference. Turned out that injecting the CR-7 monitoring circuitry in the signal path was not discernible by any listener (including a 13 years old boy and several young women). My conclusion was that there was no advantage to upgrading op-amps, since presence of several in the signal path made no audible difference.

In-Reply-To: References: Message-ID: <003001c9c4cc$47c1b760$d7452620$@com> IMO that's too much of a generalisation, Richard. The audio community seem to regard a number of the 1970s tuners better than the stuff produced today. For example, Sansui TU-919 (1979), Yamaha CT-7000, Sony AT-6B, Kenwood L-02T and L-01T, etc, just to name a few. And you could go back further than that with regard to tuners, the 1960's Leak Troughline being a prime example. Many in the UK audio industry, hi fi journalists, tech's and experienced hi fi enthusiasts regard the Troughline models 2 and 3 as being the best sounding UK designed/made tuners of all time. So, I suggest it's dangerous to generalise. As for today, I imagine you've heard of the design guru Tim de Pavaracini, whose products have long been respected for their performance. Indeed, EAR hi fi attract quite a premium and often seen in the best hi fi systems. But if you look lift the bonnet on them they are packed with "cheap" parts, not the sexy premium priced allegedly "superior" components.

Message-ID: One can use good equipment, but system matching is just as important.

BUT: I do see a very disturbing trend in our society today and it is the foolish notion that nothing can be improved on. That the engineers that made the equipment 30 or 40 years ago are somehow Gods. That their designs are sacrosanct and cant be touched. You cant possibly improve on their design, so why even try. That to be happy today, you must settle for less. To strive for something better is evil and smacks of wasteful consumerism. We all know Hi End Audio is just for rich idiots with money to burn. Mid-fi sounds just as good and costs a lot less. Happily I have never subscribed to this moronic philosophy. With very few exceptions, you get what you pay for. As to your points, I can only tell you what I heard in my system. As we know Hi End systems vary greatly in sound quality depending on the equipment used and what it is matched with. I have heard $10,000 systems that sound better then $100,000 systems. I have also heard $100,000 systems to die for. A lot depends on the component matching, your room and your cabling.

The Nakamichi's sound fine in stock form, but the better your stereo system gets, the more you will hear the differences. Also if you really want to have some fun, compare the Naks to a good reel to reel deck. I recently compared a stock 682ZX to a stock Teac X-1000R reel to reel. Using the same CD's, audio cables and record levels as reference. Being careful to not overdrive either deck. I was checking for sound quality and not dynamics. The Teac made the Nakamichi sound canned, compressed and two dimensional. And no, I was not recording too high for the Nak to handle the levels. I was also using the best Maxell matel tapes in the Nak. The Teac used the poor (by comparison) Maxell UD tape. Richard Kern In a message dated 4/23/2009 7:07:44 A.M.

I have carefully listened to many, many Naks and can't recall any of them with that kind of sound. Replacing op-amps has been discussed to death here. Years ago, I reported here on an informal listening test I conducted on my CR-7. No recording was involved, we simply compared high quality CDs played directly, with the same CDs, played through the source monitoring of the CR-7. In this ABX test, each selection was played twice (with or without the CR-7 monitoring), or twice straight through or twice with the CR-7 monitoring. Listeners were asked whether they heard any difference. Turned out that injecting the CR-7 monitoring circuitry in the signal path was not discernible by any listener (including a 13 years old boy and several young women). My conclusion was that there was no advantage to upgrading op-amps, since presence of several in the signal path made no audible difference. BTW, there is nothing wrong with the OPA2604, though I personally prefer the OPA2134 (compare specs or just listen to it and you'll see why -- it sounds very pure and clean). In very low level applications. I have found the extreme low noise of the ìPC4570 to be an advantage. -- Ron _RKern70055 at aol.com_ (mailto:RKern70055 at aol.com) wrote: I have been replacing the stock audio IC chips in my Nakamichi decks for years now and I was wondering if anyone else has tried this.

In fact one example within cassette decks will be the elaborate systems that manufacturers like Technics did to reduce W&F. Exotic quartz control, close-looped motor control and all that. At the same time, Nak was producing their simpler transports that did not need all these exotic systems but still gave superior performance in all aspects. Nak seem to use seemingly ordinary components and concentrate more on design and engineering. In fact, most of the best sounding equipment we know of was born as such. The fuss about wires, components and all those seems to come only over the last 20 or so years. Naks to me is just more then a carcass of parts that retrieve the sound off cassette tapes. It's more of the creative brilliance of a team of guys whose names we will never know. It is their work and knowhow that is ardoning our otherwise empty rack. I prefer that their design and execution be left alone. If I wanted to do something to improve on that performance, there would be so many things that I want to do. But the first thing I would do is remove that Nakamichi name because it is no longer a Nak. Rgds Graham A Nelson wrote: IMO that’s too much of a generalisation, Richard.

The Kondo pre-amp is really beautiful sounding and have become really precious now that Kondo-san is no more. As for the comparison of the 1000ZXL with the Teac, I would suggest using normal Type I tape with DBX for better results. I am getting slightly better dynamics off my X1000R with Maxell UDXL tape compared to my 1000ZXL running on That's MRXP tape. EE type, I feel, does not really live up to its hype.

In this ABX test, each selection was played twice (with or without the CR-7 monitoring), or twice straight through or twice with the CR-7 monitoring. Listeners were asked whether they heard any difference. Turned out that injecting the CR-7 monitoring circuitry in the signal path was not discernible by any listener (including a 13 years old boy and several young women). My conclusion was that there was no advantage to upgrading op-amps, since presence of several in the signal path made no audible difference. BTW, there is nothing wrong with the OPA2604, though I personally prefer the OPA2134 (compare specs or just listen to it and you'll see why -- it sounds very pure and clean).

I'll share something funny...I believe that the 480/580/680 stop lamp mute circuit was DESIGNED to create a service trip to the shop every 2 years. There was no other reason to do what they did! I repaired one prototype 480 that had every IC socketed, and a PC board without conformal (green) coating. How that ended up being sold is a mystery, but I think it proves that Nak would listen to different opamps and choose the best. We know that Dolby ICs were socketed or graded to get the flattest R/P response. This is news you can use. tom brucker -------------- next part -------------- An HTML attachment was scrubbed...

There has been mountains of literature in the engineering and audio community written on the pathetic sound of late 1970's and early 1980's IC's. Nakamichi did not use the best IC's even for the time, but considering the price point of their products they can be forgiven for it. Simply stated, 30 years have passed and there is no comparison to today's IC's. The real fallacy of your argument can easily be exposed. All one has to do is mount an IC socket in the deck and swap out the stock IC. You can then try as many new chips as you wish and if you don't like any of them, you can put the original IC back in.   Richard Kern     In a message dated 4/23/2009 7:35:41 P.M.

What's "crap" is hyperbolic writing like that. The JRC-branded ICs used by Nakamichi are still excellent sound, even by today's standards; it's just as different sound than Burr-Brown or Analog Devices. Design technique is more important than the specific opamp; Nakamichi worked wonders with the chips they chose.    Although I will admit I gave up finding an opamp I personally enjoyed, so I now make my own opamps from my own design. Alas, they aren't pin-compatible with those Nakamichi used, otherwise I'd sell them as upgrades.

But somehow, the reels turning are just so enticing! And the sound gains a life on its own which is very difficult for other mediums to do (not impossible thought - I know a few cassette decks that CAN do that..but let's not get into that again!) After much investments it flagship machines of the various medium, I still find that reels are just simply something different! Rgds benstratford at aol.co.uk wrote: Bala, I totally agree. Having tried EE tapes recently I was disappointed. But the Maxell XL1 tapes on the Teac X-2000M at 15ips - amazing. Too cumbersome and took up too much space though, so now the deck is history. A worthwhile review though which will be hard to forget. rgds, ben -----Original Message----- From: Bala Ganesh Chandra To: Talk about Nakamichi Cassette Decks Sent: Fri, 24 Apr 2009 8:09 Subject: [naktalk] Of reels, Naks and Tapes Hi George, First of all, impressive set-up! The Kondo pre-amp is really beautiful sounding and have become really precious now that Kondo-san is no more. As for the comparison of the 1000ZXL with the Teac, I would suggest using normal Type I tape with DBX for better results. I am getting slightly better dynamics off my X1000R with Maxell UDXL tape compared to my 1000ZXL running on That's MRXP tape. EE type, I feel, does not really live up to its hype. Rgds BG george valkov wrote: I have compared a stock (but calibrated and in perfect working order) 1000ZXL (TDK SA) with NR-200 to a brand-new stock TEAC X-2000R (Maxell EE) in my main system and the differences are negligible, if at all noticeable. And before you even mention Mid Fi again: Wilson Audio Alexandria X2, Kondo Audio Note M-1000 Mk II, Kondo Audio Note Gakuon II, Valhalla Odin cabling, PS Audio power plants, Kuzma Stabi XL with Airline arm and Koetsu Blue Onyx Platinum, the full 4-piece dCS Scarlatti setup. I guess there are no absolutes in our universe and we simply need to learn to live with that.

The Nakamichi's sound fine in stock form, but the better your stereo system gets, the more you will hear the differences. Also if you really want to have some fun, compare the Naks to a good reel to reel deck. I recently compared a stock 682ZX to a stock Teac X-1000R reel to reel. Using the same CD's, audio cables and record levels as reference. Being careful to not overdrive either deck. I was checking for sound quality and not dynamics. The Teac made the Nakamichi sound canned, compress ed and two dimensional. And no, I was not recording too high for the Nak to handle the levels. I was also using the best Maxell matel tapes in the Nak. The Teac used the poor (by comparison) Maxell UD tape. Richard Kern In a message dated 4/23/2009 7:07:44 A.M. Pacific Daylight Time, ra.ah at verizon.net writes: I wonder what Nak model you find to have a "dry, gritty, canned sound". I have carefully listened to many, many Naks and can't recall any of them with that kind of sound. Replacing op-amps has been discussed to death here. Years ago, I reported here on an informal listening test I conducted on my CR-7. No recording was involved, we simply compared high quality CDs played directly, with the same CDs, played through the source monitoring of the CR-7. In this ABX test, each selection was played twice (with or without the CR-7 monitoring), or twice straight through or twice with the CR-7 monitoring. Listen ers were asked whether they heard any difference. Turned out that injecting the CR-7 monitoring circuitry in the signal path was not discernible by any listener (including a 13 years old boy and several young women). My conclusion was that there was no advantage to upgrading op-amps, since presence of several in the signal path made no audible difference. BTW, there is nothing wrong with the OPA2604, though I personally prefer the OPA2134 (compare specs or just listen to it and you'll see why -- it sounds very pure and clean). In very low level applications. I have found the extreme low noise of the ìPC4570 to be an advantage. -- Ron RKern70055 at aol.com wrote: I have been replacing the stock audio IC chips in my Nakamichi decks for years now and I was wondering if anyone else has tried this.

In-Reply-To: <49F1A2DA.3050406@yahoo.ca> Message-ID: <852281.23160.qm@web30206.mail.mud.yahoo.com> Antoine, This is my very observation. This is the same thing I am hearing it with people with Marantz CD players and other similar range equipment. But you never hear about people tearing into the guts of their Krell, MBL, McIntosh or other similar equipment. It's nit just about price but usually by trying to stand on the head of those creators is as good as questioning them and that is something I would not want to do. If I feel that I can do something about what I have, it's best to leave it to guys like de Paravicini or come up with something myself. But I feel that a stock Nak has so much in it. When I started to listen to Naks, my system was much different from what it is now. As key components evolved over the years, the Naks remained. The lows got lower, the trebles got more transparent and richer. The soundstage started to open up...and the evolution has not stopped. And yet the source has remained constant.

Everything you say sounds like very subjective observations without comparison, and just seems to be placebo, which is extremely common on forums like AudioKarma and DIYaudio where everyone is thitnking tweaking and changing components will obviously make the circuit sound better because, er..., everyone believes that. I've already AB'd many of those "improvements" (changing your RCA and speaker cables, bypassing a buffer/muting transistors/etc., changing opamps), and never did one improve the sound.

Reel to reels do offer better fidelity then cassettes, depending on the quality of the reel to reel and the blank tape you use. In the 70's I worked on a lot of poor quality, low cost reel to reels machines, mostly from Sony and Akai. These sets could easily be beaten by a Nakamichi.

Hyperbolic writing, not fact. There's also a large body of literature disputing what you've said. So what? Who cares which position is correct? "Best sound" is nothing more than opinion, just as are discussions of which is the "tastiest" food, "prettiest" color, "best" music, &c. But to respond to your remark, it's odd then that some of the highest- regarded equipment even today was made back then with those "pathetic" ICs. I stand by my statement, design technique is more important than the specific choice of IC, or other component. At least that's what my past 35 years of experience has been. And that experience includes designing opamps from scratch, not merely designing equipment using opamps. > Nakamichi did not use the best IC's even for the time, but > considering the price point of their products > they can be forgiven for it.

My point was not which was the better/best ICs, but that changing the IC changes the sound.

It's all about the sound and whether an individual likes the sound. "Better chips" doesn't inevitably mean a listener will prefer the altered sound. -- Kermit Gray notarbene at kvglabs.com KVG Laboratories Equipment to Make Your Music Better 16371 Lake Point Drive Bonner Springs, KS 66012 USA Telephone: 913-422-0957 Skype ID: triodelicacy -------------- next part -------------- An HTML attachment was scrubbed...

Well, again, the "improvement" is simply your opinion, and I respect that, but it's not a fact. "Reference" is arbitrary and inherently subjective, hence opinion. My reference is usually live sound, not other equipment. As a mastering engineer, and owner of a recording studio, this is a convenient reference for me. -- Kermit Gray notarbene at kvglabs.com KVG Laboratories Equipment to Make Your Music Better 16371 Lake Point Drive Bonner Springs, KS 66012 USA Telephone: 913-422-0957 Skype ID: triodelicacy -------------- next part -------------- An HTML attachment was scrubbed...

In-Reply-To: References: Message-ID: <000801c9c52f$bf687ac0$3e397040$@com> But by whose standard is it an improvement, Richard? We can have a technical spec that proves an item is technically superior, but whether or not it sounds better is a subjective, not an objective, judgement. Each person has their own view of what is best ... for them personally. For example I know folk who swear that replacing the paper caps in a Leak 20 amp with Black Gates improves the sound whereas I know others who reckon it ruins the sound. Who is right? Here is a Nak example. The Arcam Delta 100 cassette deck was designed and went to market originally meant to compete head of with some of the top Naks, esp. the CR7 ... except Nakamichi stopped production at around the time the Arcam came onto the market. It was designed using many of the most up-to-date components - that is, more up-to-date than the Nakamichi CR7. And its design showed measurably superior specs - for example S/N 66dB with Dolby off. Yes, off. And it achieved 88dB with Dolby S NR on. Eat your heart out, Nakamichi! These are specs Nakamichi could only have dreamt about ... except they didn't because they didn't really care about cassette by then! But to my ear, and to many others as well, the more "inferior" Naks sound better than the Arcam ... but that is a subjective judgement because I am sure - I know - that others disagree and think the Arcam has a much more "natural" sound than any Nak, and especially my ZX9.

Look up on the web Tim de Pavaracini and see what kind of products he has designed and where they sell in the hi fi market. Read all the reviews and other comments about his products. I’ve never read a bad one. He achieves that success with the adoration of consumers, designers, manufacturers and hi fi pundits using bog-standard components – you might just be right about his products but if you are, you’re in a minority holding that view about EAR hi fi. But as I have said before and others here too, what is better in terms of subjective judgement is just that – subjective. What suits your ears may not suit others, may not suit anyones!

As someone who has owned classic and modern tuners, has listened to them in both stock and modified form I stand by my past statements. In fact I will make the following statement as a clarification. Modern IC's will improve the sound of any audio product made 20 to 30 years ago. You have nothing to lose and everything to gain by replacing old parts with new ones. Richard Kern PS. Graham, too many companies today use cheap parts inside their designs and call themselves Hi-End companies. They should be run out of business.

Graham: Your position is just as much a generalization as mine, [Graham Nelson] I am pleased you have felt able to concede your position is (also) a generalisation using your logic. There are plenty of examples of Hi-Fi equipment that use the best parts as well as the best engineering and are revered the world over for their sonic quality. Mark Levinson, Jeff Rowland, Ayre, Spectral, Air Tight, BAT, Audio Research, Lamm, Sim Audio, Bryston, etc. [Graham Nelson] I agree, they are revered; my point is so too are some companies revered that are not crammed full of “the best” components, like those of EAR and even Nakamichi when compared with some other makes of cassette machines. Partly as an aside, I was very disappointed when I heard the “sonic quality” of some Audio Research kit at a hi fi show in Manchester a few years back, especially having heard a “budget” combination at the place of amp, CD and speakers totalling about £1,200 that sounded better to my taste. (BTW, I used to be a musician and am used to hearing some instruments live, so I judge the sound from hi fi set ups according to what I remember of the same instruments in a live performance.) The hi fi journalist who chose the budget kit put it to me, “it’s all about synergy between each bit of equipment.”Of course, that isn’t the whole story but his point about synergy is valid, I think - the best components can make a bit of kit sound awful if they don’t marry well with those being used in another item in the audio chain, i.e. a Levinson may not always sound so good though some top end speakers as it does through others. It’s a lot like that comedy sketch with Eric Morecombe and the conductor, Andre Previn. Eric failed to play on the piano the same tune as the orchestra. Previn railed at him, “You’re playing all the wrong notes!” Eric answered, “I am playing all the RIGHT notes ... but not necessarily in the right order.” I could go on but what's the point. [Graham Nelson] Quite so – no point at all, so it’s best to leave this subject and move on before everyone gets bored/irritated with it. ;o) <> Richard Kern In a message dated 4/24/2009 4:15:41 P.M.

A person's disagreement with your opinions on the matter are NOT the same as, and cannot be construed to be, their "refusal" to try modifying a piece of equipment. I think you'll find that many of those who did disagree with you were those who HAD modified equipment and found little or no improvement to their ears, or had preferred the sound of the stock version. I'm one of those, by the way. If you wan to accuse those who disagree with you of something, please make the accusation due and proper. -- Kermit Gray notarbene at kvglabs.com KVG Laboratories Equipment to Make Your Music Better 16371 Lake Point Drive Bonner Springs, KS 66012 USA Telephone: 913-422-0957 Skype ID: triodelicacy -------------- next part -------------- An HTML attachment was scrubbed...

This is one of Nak's better vintage two head decks, with many features: Play and REC timer support, memory stop, auto repeat, master fader, Dolby B and C. This deck was manufactured in 4th quarter of 1986. I recently went over it: new idler tire and capstan belt, adjusted speed and azimuth. It works well and sounds good. Mechanical condition is very good, with clean capstans, good pinch rollers and no visible head wear at all Cosmetically, there is evidence of usage -- most notably, scuff marks on the fader push button plus some wear on the top. There are no obvious scratches and no dents at all. Bottom line: this is an excellent choice for someone that wants to record and listen to music, but not necessarily for the finicky collector. Asking $75 plus actual shipping (or pick up in the Boston Metro west area, ZIP 01702) Includes copies of both the user's and service manuals. I'll be happy to email pictures -- Ron -------------- next part -------------- An HTML attachment was scrubbed...

I think the amp sounds great, but, never A/B'd it anything else.  SJ ________________________________ From: "benstratford at aol.co.uk" To: naktalk at naks.com Sent: Sunday, April 26, 2009 1:10:21 PM Subject: Re: [naktalk] 730 Receiver Tom, Thanks for the part number, I will indeed try Jeff to see if he has any.  Will enquire for you also Scott.  Anyway, how does the tuner sound?  Any comments of the amp when working ok?

So, here's the revised plan. I hope everyone who is interested contributes to the wiki list of desired parts. After a list begins to appear, I'll consult with my friend and get the thumbs up/thumb down on what my machine can make and what it cannot make. Then I'll post a list of what parts can be done. I am planning to add a CNC milling machine next year, if all goes well. Hopefully whatever the CNC router cannot do the CNC milling machine will be able to do. My bottom line is that I want to, as much as possible, make replacement parts for Nakamichi machines, if not now then soon. It's been a dream of mine for years.

I have seen on the net that this problem is not unique to my Dragon; however I have found no solutions posted. Before I go to the extreme of replacing a 42 pin micro processor that is unit specific, "LM6402A-052" to Nakamichi (it also comes in LX-3's and ZX-7's) I was hoping that there is a different solution. Maybe a work around that some one else has come up with maybe I missed something. I fear that surgery of this type might be a 2 day trip into hell. Any suggestions?

I wonder what would cause an unknown tech to replace the IC602 processor. The deck must have had a transport control problem to start with, that (correctly or not) he concluded was caused by the processor. This means that after replacing IC602, you may still find a problem. The Dragon it not a deck that someone would lightly junk for parts, so I suspect finding a working logic board will be difficult. While pursuing your plan C. I would still try plan B and look for a *new* IC602. Maybe, where you got the IC601, or Jeff Galin, or even Nakamichi in CA. If neither plan works, there is still the possibility of emulating the behaviour of IC602 with a modern processor. However, this is a huge, truly heroic job.

There are 6 or 8 of us who can check and compare with decks we are working on. It is very common for a micro to have different program codes, the numbers after the dash, in a factory update not accompanied by a parts change bulletin. Also, look at the part number in the Nakamichi price list, posted on Naks.com wiki page. Often generic IC numbers AND crosslisted or substituted parts appear on this list! I may have a board for you, however, my experience with micros is that the problem is usually somewhere else.

Second, you may wish to power the V+ and VL pins off +12V and +5V respectively (V- at ground or -12V). I will look at that Third, I am not sure why you need the 2N3609 transistor. Why not drive the DG419 directly from the Lplay line and swap the switch sections? The 2n3609 is a low pass simple logicfilter that passes 5v to the DG419 only on the low from the play back latch circui (normally rides high)t. Granted, I haven't gone over the DG419 data and app notes, so I may be wrong. These are just random questions that popped up as I was looking at your circuit.

Do not attempt without ruling out other possibilities Your Processor may be OK and the processor senses positions of the cam and selects the mode. It is likely that this sensing area needs to be fixed for your processor to allow play mode - you are misjudging that as processor is bad- my guess ( but worth looking at the problem this way) Your Tech is has no idea how Nak Dragon works   If you are in the US - send it to one of the techs who can work on this to find the faulty component - rather than replacing Processors or boards   My experience with Dragon - it is well thought of schematics - Electronics can be repaired without touching the processor.

There are 6 or 8 of us who can check and compare with decks we are working on. It is very common for a micro to have different program codes, the numbers after the dash, in a factory update not accompanied by a parts change bulletin. Also, look at the part number in the Nakamichi price list, posted on Naks.com wiki page. Often generic IC numbers  AND crosslisted or substituted parts appear on this list! I may have a board for you, however, my experience with micros is that the problem is usually somewhere else. Nakamichi used non-protected gate CMOS 40xx series ICs, and they fail like crazy.   tom bucker -----Original Message----- From: Chris Kamachi - Shaw Sent: Apr 27, 2009 6:14 PM To: ' Talk about Nakamichi Cassette Decks ' Subject: RE: [naktalk] Dragon and Reel Motor Control Circuit Well after an hour of work I replaced the IC601 MPU, only to find the IC602 has been replaced by a non standard chip with the wrong numbers on it.   The system still exsibits the same behavior.   I think I will go to plan “C”. assume the Logic PCB is defective and replace the unit if I can or buy a new Dragon and lever this one for the bone yard.   Has any one got a Dragon logic board they want to sell?   Thanks Chris From: naktalk-bounces at naks.com [mailto:naktalk-bounces at naks.com] On Behalf Of Chris Kamachi - Shaw Sent: Tuesday, April 21, 2009 4:03 PM To: ' Talk about Nakamichi Cassette Decks ' Subject: RE: [naktalk] Dragon and Reel Motor Control Circuit   Well for those that are following my Dragon saga got the NOS chip from Nak Japan today.

If I feel the fit is week I add cyanolitic glue, but actually this should not be needed. I never put grease on the joint again. My decks are rarely used and will have little wear. The pivot bushing is fairly large and movement is very small. This is my choice to avoid hardening of the grease acting up on me ever again. I also do not lock the nuts when they are set to the correct height. Simple paint is possible. Cyanolite is a possibility too.

It can't be way off, since it's held in place by the circlip. The tolerance may be loose, but it's good enough for directing the tape onto a cassette shell. It's not precise enough for directing the tape into the head path (at least, not for top-of-the-line decks). -- Ron > Otherwise why have an adjuster and not just a circlip to enable > location in the ball park? > Rgds, Ben > > > > -----Original Message----- > From: Ron > To: Talk about Nakamichi Cassette Decks > Sent: Wed, 29 Apr 2009 20:15 > Subject: Re: [naktalk] Frozen Pivots > > benstratford at aol.co.uk wrote: >> Hi Doug & Henk, >> Clear nail polish is what I had in mind as a possible solution, but >> do these nylon nuts actually move?

It has up and down volume buttons (not a rotary control), and when it's turned on, there is often no initial sound. I can usually get it to start playing by turning the volume up significantly (until it goes over some sort of threshold and starts making music again); once I've done this, I can turn it back down and it works OK. It can also be coaxed into working again with a few firm 'thumps' on the top left front (which is near the ventilation slots). During these outages, I continue to hear sound from both channels of the subwoofer (yes, the R-1 has pre-out/main-in jacks!), which narrows down where the likely source is. I'm thinking that there are some oxidized contacts where the signal feeds into the power output section of the amp, that act like a capacitor until the increased voltage from the increased volume breaks through. I'm going to dissect it in the next few days to see if a good cleaning with De-Oxit will fix the problem. Any other suggestions, besides getting a larger hammer?

You have to decide whether you're technically inclined enough for a DIY approach. If so, proceed as follows. To discover what kind of idler your deck has, remove the black backing plate from the cassette well. To do that, place the deck on its rear panel, remove the door and undo the 2 tiny black screws at the top of the plate. Then pry the plate up at the top and remove it. You will see the idler, more or less in the middle area of the transport. It could be either a plastic wheel with a black rubber tire, or a toothed gear. Now plug the deck in and turn it on. Press FF. The brass reel motor pulley should start to turn. The Idler should move to rest against the right hub and rotate it. Lightly touch the pulley top and note whether the torque is enough. If so, the reel motor is good. *(Do not touch the idler)*. Then, lightly touch the hub top. Do *not* try to stop it, just to feel whether the torque is enough. Based on your description, it probably won't be. At this point, it should be easy to determine why.

It sounds very much like a speaker protection relay problem. If the contacts of such a relay are oxidised or damaged, you often don't get signal to your speakers until you apply sufficient signal voltage to the relay contacts to cause arcing. As soon as this point is reached (by turning up the volume), the contacts conduct and you can reduce the volume setting. This annoying behaviour is present at the moment in my Accuphase E-303 amplifer in my home system. The remedy is to either replace the relay, or clean its contacts. You can get at the contacts in most relays, and use either a spray contact cleaner, or a treated paper type contact cleaner (very fine abrasive). One other possibility with pretty much the same symptom is a bad joint where the relay is soldered to the PCB -? relays develop bad joints sometimes over a long period of use because they couple a small mechanical shock into the PCB via the solder joints every time the relay coil is energised. Your Receiver 1 has two speaker relays - one for Speaker Pair A and one for Pair B. As an experiment, you could try changing over to the B speaker terminals and see if the behaviour is different. Also, with the case removed, try a light tap on the relay cover to test whether it is the problem. The relays are designated RY301 and RY302. The Receiver 1 is also known as the RE-1 - you have referred to R-1 - I'm assuming the same or very similar device.

Load the plate into the cassette well and use the bar for calibration. When the bar is laid flat with the square end toward the guides it will provide guide height calibration. When it is laid upright with the flat end against the heads and the machine in play, the sloped end will provide you with the proper head stroke.

Load the plate into the cassette well and use the bar for calibration. When the bar is laid flat with the square end toward the guides it will provide guide height calibration. When it is laid upright with the flat end against the heads and the machine in play, the sloped end will provide you with the proper head stroke.

Blame Nakamichi marketing for all of these confusing models! I'll have to check around inside for an output relay to clean, and check for bad solder joints; I think I can remember hearing it 'clunk' around in there when I power it up; however, I'll often get only one channel working and not both at first.

I was very pleased with the machine, until it started creasing certain tapes at the beginning of each side. Why I say "certain tapes" is because it only does this to thinner tapes, and among thinner tapes of the same type, only certain ones get damaged. For instance, I have a bunch of TDK D90 tapes that all play fine in any other machine. The older ones are thicker than the newer ones...and all of the old ones play flawlessly in the DR-1. However, about half of the newer (thinner) ones get creased whenever I play them in this machine. I am pretty sure that my hypothesis about thinner tapes is correct, as the same effect is there with my Maxell tapes too (this time the older ones are thinner than the new ones, and only the old ones get damaged in the Nakamichi). But the creasing only happens at the very beginning of a tape...any of the thin tapes will play fine if I start about 1 or 2 minutes into the tape. The only thing I found on the internet was that the problem may be a loose capstan belt? I was just wondering if anyone has had any experience with these types of problems, and if so, whether they think that a loose capstan belt, or something else, may be to blame. Regardless of what is causing the problem, I just wanted to know whether I would be able to fix it myself, or whether I would need to send it somewhere for service. I just don't want any more tapes to get damaged by this machine! Any advice or information would be greatly appreciated...thanks. -------------- next part -------------- An HTML attachment was scrubbed...

If you remove the black back plate of the transport you'll find a toothed wheel to the left of the left hand hub. There is supposed to be a small belt running between the supply hub and that wheel. When the machine goes into play there is a metal lever that moves to the left and a finger of that lever which slips into one of the gears of that wheel stopping it and forcing the take up hub to spin against the clutch beneath that gear increasing the back tension for play. I have found that some machines which have been worked on by "others" have had that belt removed or the lever bent to the right to prevent it from contacting the geared wheel. I have also seen a couple where that belt became the consistency of warm Brie and was wrapped around the gear or hub. If all that looks good, change out the capstan belt but chose the replacement carefully since a poor quality capstan belt can substantially increase the wow and flutter. Best of luck.

Since the machines of yesteryear were never configured to run well, if at all, with the longer length tapes, it's doubtful whether you can get any operational consistency running 100-120 minute tapes on older machines unless you modify tape handling of the bad decks.

I can only add one thing, sometimes the problem can be lessened if the pinch rollers are given a good cleaning. Sometimes, and only in rather extreme cases, the deck will begin to crease tapes because there is so much dirt and oxide buildup on one or both pinch rollers that they can no longer grab the tape the way they should. But most often, the creasing is due to the factors that Willy mentioned. *andy* -------------- next part -------------- An HTML attachment was scrubbed...

Message-ID: <555884205.257511250441705947.JavaMail.root@sz0075a.westchester.pa.mail.comcast.net> Hello All: A good customer sent me his Dragon to work on. He stated that the deck worked, but he could hear clicking during playback. I originally suspected the playback azimuth mechanism might be out of adjustment, but on further inspection, it was something else -- something I have never encountered before. Instead of being perfectly smooth around the circumference, both of the reel tables were actually pitted, with several "potholes" on each reel table where the idler wheel contacts them. The clicking sound is actually the sound of the idler wheel assembly as it bumps over the "potholes" during playback. Since both reel tables are in the same condition, the clicking persists in either play direction. The deck sounds perfect electronically, but mechanically you can hear the clicking, especially if you put your ear close to the top of the deck during playback. I haven't yet measured wow/flutter, but I will be interested in the results, knowing how the reel tables look. Has anyone else encountered this pitting on the surface of the reel tables on any deck? Very strange..... *andy* -------------- next part -------------- An HTML attachment was scrubbed...

This will make sure any latent tape looseness is minimized at the beginning. In your case, while this does not fix the root cause at least it may help in the short term before you service your machine. Every tape is different, even within the same brand. Some are tighter than others, especially if not played for a long time.

I was very pleased with the machine, until it started creasing certain tapes at the beginning of each side. Why I say "certain tapes" is because it only does this to thinner tapes, and among thinner tapes of the same type, only certain ones get damaged. For instance, I have a bunch of TDK D90 tapes that all play fine in any other machine. The older ones are thicker than the newer ones...and all of the old ones play flawlessly in the DR-1. However, about half of the newer (thinner) ones get creased whenever I play them in this machine. I am pretty sure that my hypothesis about thinner tapes is correct, as the same effect is there with my Maxell tapes too (this time the older ones are thinner than the new ones, and only the old ones get damaged in the Nakamichi).

LOL ANDY ----- Original Message ----- From: Jim Tuller To: hwbosshoss at comcast.net Sent: Mon, 17 Aug 2009 17:55:10 +0000 (UTC) Subject: Reel Table Pitting Hi, Andy I was interested to read about the reel table pitting problem. Are those metal surfaces? I've never worked on this deck, but I know that atmospheric conditions can speed up pitting of metal surfaces. If it's metal , it sounds like the deck was stored somewhere, like an oceanfront community, where corrosion can be dramatically accelerated. You may wish to examine other metal surfaces for signs of this, and ask the customer where the deck was located. (He may have acquired it used.) The fact that it is on both tables makes me think it could be something in the air. Not only ocean salt, but many air pollutants like SO2 can accelerate corrosion. If the corrosion can be removed and the metal protected (WD 40?) it should be OK if it is stored under normal conditions. You may be able to get the surface close enough to the original contour for normal operation. Good luck with the repair, I hope you get some useful suggestions from your post.

If you can find some pre-records that center, then you've had bad luck with the pre-records and your decks are ok. Try recording the bias adjust 10kHz with your Dragon, and play back on your DR1. Is the azimuth knob on center? If so, then the 2 decks agree and your pre-recorded cassettes are not so good. I suggest everyone have some sort of reference tape that they label as a known good tape. It doesn't have to be a test tape. Having a tape whih you have confidence in aids troubleshooting.

Now my Dragon as never been aligned to my knowledge, I just bought it about a month ago and it played and recorded fine so this was that only issue I've encountered. When it does start clicking I take thhe tape out as I can assume that to leave it banging off one side of the azimuth motor can't be good. I did also notice the azimuth adjust on my DR-1 with the same tape had to be set to the 4 o clock position and the dial doesn't go much pas 5. So I assume as with almost all prerecorded tapes quality is low to mediocre. Stay on top of things, check email from other accounts!

It doesn't look like a conventional motor. The motor likely to cause your problem is the reel motor (that's the one 'powering the gear idler'.). IME, spraying contact cleaner into the motor seldom solves the problem for long, if at all. However, other people, luckier than me, swear by it. Since you do not have a rubber idler to deal with (you did say yours is a gear idler, right?), this motor is the next thing to tackle. Either replace it with a known good one (your best bet), or rebuild it (this has a finite chance of 'no success', but is worthwhile to try). In either case, it has to be taken out. Not difficult, but not for the faint of heart, either :-). -- Ron jesse ruff wrote: > So after I sprayed some deoxit into the contol motor (the larger one > powering the gear idler) and one of the rear motors (the one on the > right--I didn't even see a third motor), it played a tape all the way > through until the very end of the b-side when it did its usual routine > of stopping and pulling a little tape out.

Test it as above, several times. It should start reliably, at the same voltage, every time. Also, stop it with a finger, then release, several times. > Why did Nak cheap on the motor? Depends on your definition of 'cheap'. They could have got motors for a fraction of the price. > Or is it customary for motors to fail this frequently? Depends on your definition of 'frequently'. These motors run reliably, in deck after deck after deck, for over 25 years. Do you know of a current product that you think will last half that long? How about any motor in your new car? > Guess mine saw a lot of use? Seems like motors should be the least of your > worries with a renown tape deck... Why do you think that? The first to go is *always* the mechanical stuff. I wonder if any of the transistors or ICs have failed so far? And, BTW, Nakamichi decks are renowned for exemplary performance, not for longevity. Even so, there are very few manufacturers whose decks are still running after 25 years. > What's a rebuild entail? Take the motor apart. Burnish commutator and brushes. Clean and lubricate.

Deoxit has the advantage of name recognition and uses that advantage to charge exorbitant prices, similar to Servisol in England (also, excellent chemical and also, not necessarily better than quality competition). Personally, I still use the 'Contact Cleaner' and 'Contact Cleaner with Lubricant ", made by T.A. Emerald Industries (who ever heard of *them*?), that I buy from All Electronics for less than 7 buck per 13 oz. spray can. Excellent stuff.

I have several sets of digital calipers with resolution at .0005 inches which are also part of the same daily routine. My residence is in South Western N.H. on the MA border. Pretty much diagonally opposite from you in the lower 48. Could you post a digitized picture of this gauge that you borrowed from the gentleman in GB ?  I also have a universal gauge some where in my collection of stuff obtained back in the late 70's. This gives rise to the curiosities in similarities, etc. Also to see the complexities of the various  radii and alignment troughs or channels on your existing gauge.   Anyway, I could also highly recommend several places that could do the replication to speck from drawings, using high grade tooling stainless steel, highly polished.   The next step would be to make the necessary measurements of the gauge.  What would you suggest ?

I have a ZX7 and BX300 and would like to be able to keep the heads aligned. I remember lots of stuff about Louis's tapes last time I logged on as well as the cost of Nak test tapes. If I had this gauge and a tape with the tones, would bI be able to fine tune alignment etc. I have some experience here. I have an Ampex test tape with lots of tones on it which I could supply to the Naks in the same way I keep my R to R machines up to scratch.

The typical feeler block is tapered to a squared off point, whick allows a better view of the head when the guide is attached. From the price I'd say Nakamichi added a bit of markup.

Nakamichi recommended using D5 on the troublesome PCB contacts on the 1000 and 1000II tape decks. I have found that while not a panacea the D5 is a wonderful "audio grade" contact cleaner. It does not work well with certain plastic based controls such as those used in Yamaha equipment. The old Channel Master TV Tuner Cleaner/Lubricant works better for those controls and switches. When using the D5 it is always best to adhere to Caig Lab's recommendation of "the less used, the better results". It is best to spray it on a swab and then use the swap to clean a contact and only spray it directly into switches or pots that can't be disassembled first. The aerosol carrier for D5 will adversely effect some plastics and it is never good to get anything on rubber belts. If D5 is used just where it is designed to be used it works quite well and has solved many of the "Be Back" repairs that used to plague audio service centers.

In-Reply-To: <286516.88420.qm@web110316.mail.gq1.yahoo.com> Message-ID: Test tapes are the labratory references which exist to make tapes interchangeable from deck to deck. Test tapes are used to peak the performance on an individual deck, and match closely every other deck. I believe a solid technical knowledge is required to use some test tapes properly, however Dolby operating level "0Vu" tapes are useful to anyone willing to learn a bit. Azimuth tapes require some method to visually monitor the adjustment (actually a MONO system works pretty well) such as a dual channel AC voltmeter or an oscilloscope. Speed tapes are very useful, but one needs a special meter, or a minimum of frequency counter or guitar tuner to benefit. On most of my repairs I provide a recorded reference tape with level, azimuth, and speed tones so that tape serves as a snapshot of the deck's alignment. Studios will always record level tones at many frequencies to 'label' their recordings with references. I would say the average cassette user would not want a test tape. We do promote learning about these techniques! tom brucker -----Original Message----- From: naktalk-bounces at naks.com [mailto:naktalk-bounces at naks.com]On Behalf Of ying yang Sent: Friday, August 28, 2009 1:04 AM To: Talk about Nakamichi Cassette Decks Subject: Re: [naktalk] Nak Test Tapes on Ebay ex Austria?

Some people sell this stuff "duplicated" not just on a ZX-9 but on a Dragon. And if that's the case how does one get hold of this tape or go around it? I've had to change pinch rollers on my 582. I've managed to adjust the guide heights and the deck sounds good right now but I am sure it needs a pb head height adjustment after this operation.

This tape produces a null (ideally, zero output) at the correct head height. Making this tape requires a deck with a special head, that probably none on the duplicators have Simply duplicating it on a standard deck produces a useless tape. That's because the signal on this tape can be neither read not recorded by standard heads. A tape that contains a signal on both tracks (at the exactly correct height) -- and not in between -- can be used, by adjusting for a peak (maximum signal). This is not as accurate as adjusting for a null with the Nak tape, because the correct point is not as sharply defined. Still, it can certainly produce acceptable results with care. Such a tape can be made on any *correctly aligned* deck -- Ron Peter Tanner wrote: > Hi Willy, > > Does this mean that all the other 1khz track alignment tapes floating > around on Ebay and elsewhere are not good as the original DA09007A > Nakamichi tape cannot be duplicated?

The azimuth adjust on the ZX-7 is for the record head and aligns its azimuth with its own play head. Once done, you can use that tape to adjust the play head azimuth on your BX-300 by looking for maximum play output. At that point you will have matched the play azimuth on the two decks. If it was wrong on the ZX-7 you will have duplicated that error on the BX-300. Presuming it's all correct, you can set the record head azimuth on the BX-300 for maximum high frequency response. The right way to do it is with a signal generator but you can come very close by using white noise (like a de-tuned FM radio) and adjusting the record head azimuth as you listen to the playback. The biggest danger with any of the home brew test tapes out there is that they are dependent on the set up of the recording deck. Also, as Ron just detailed, the height adjust tape cannot be duplicated on a regular cassette deck. I might also add, the 3kHz wow/speed tape is very dependent on the recording machine. I'm sure Nakamichi made those tapes on a modified open reel deck in order to obtain wow and flutter low enough to be used as a measurement standard. BTW - I recall that there was someone on NakTalk who was working with a Studer open reel transport and was coming close to the ability to reproduce these tapes accurately. Still out there?

That's why all test tapes are one side use only. However, if a machine's play azimuth has been set correctly with a professional alignment tape and (like the ZX-7) you are able to exactly align the record azimuth of that machine to the play head you should be able to make a 15kHz tape which will allow you to transfer that azimuth to another deck. I guess we all learned that with cassettes there is always a skew in azimuth and we lived with it -- except for Dragon owners whose machines set the correct play azimuth for each tape and each side they play.

Play and Record heads have been thoroughly cleaned and de-magged, had height and azimuth carefully adjusted using (20 dB down) test tones recorded on my pristine ZX-9, (which as already discussed, is not as good as genuine test tapes, but all I have at this stage). This frequency drop-off is I believe associated with the head as I can swap the head channels and transfer the frequency roll off to the other (left channel). It is also measurable with a CRO very early in the head amp circuit. Upon examining the head, I can see what I think looks like a flatter than the preferred profile but thought that the left and right channels would deteriorate at much the same rate in terms of gap wear. Anyway, looking at my ZX-9 service manual, I note that there are a couple of resistors associated with both the Head Amp and Dolby Circuits that are "select on test" based on initial frequency response measurements in addition to some resistors that can be shorted out in order to improve the equalisation response. Unfortunately, the 482 Service Manual I purchased form servicemanuals.net is missing pages 35, 36 and 37 or section 7.2 in the PDF scan, which is where this detail is.

One channel (usually the outside one) deteriorates faster than the other and your measurements are classic for worn play head. The playback frequency adjustments will gain you a maximum at 4dB at 20kHz and are intended for tailoring the deck to slight head variations. If you want to verify that, find R111(211) and R112(212) on either side of L101 and L201. Shorting R112 should give you 2dB and R212 an additional 2dB at 20kHz. If you don't have a replacement head you can probably get it lapped. Nak heads are generally deep enough to lap at least once.

The answer here is very simple - TDK.  Why?  Because Nakamichi tapes SX and ZX were all TDK tapes.  Nak had a contract with TDK to have TDK manufacture all of Naks tapes.  Nak simply re-named them.  Specifically, Nak SX was TDK SA (chrome) and Nak ZX was TDK MA (metal).  So, all Nak decks were calibrated for TDK tapes.  In fact, when one purchased a high-end Nak deck back then, included was a sample cassette tape recorded by Nak in Nak's recording studio (using a ZX-9 deck), and the label of this tape says TDK MA.  However, there is a rumor that Nak told TDK to cut their tapes from the center of the TDK long factory spools, since Nak considered tapes from the center of the spool to be of a higher quality than those cut from the ends.   Jayson ________________________________ From: Tim and Pam Sepper To: Naktalk at naks.com Sent: Mon, November 30, 2009 10:37:09 PM Subject: [naktalk] RE: Blank Tape Is Still Available All this talk of blank tapes has me wondering.  What is the best tape for a Nakamichi deck?  Obviously, the purist would say Nakamichi’s own SX and ZX tapes, but those are prohibitively expensive and nearly unobtainable.  There seems to be a lot of Maxell and TDK tapes available on ebay, but the variety is bewildering: UD, XLII, XLII-S, SA, SA-X, etc..  There are also tapes from Sony, Fuji, BASF, others.  My DR-1 will adjust bias, but not level.  Without internally fine-tuning the deck’s settings, which tapes are the “best” for Type II and Type IV settings?  (I had been using older Maxell XLII and TDK MA tapes).   Thanks,   Tim -------------- next part -------------- An HTML attachment was scrubbed...

Well, it's not a transformer, just a coil. Usually, wound on a U or E core with no metallic end bar. Thus, there is a concentrated magnetic field between the open U or E ends. It's usually housed in a plastic box, with a handle and trigger switch for power. > How close must it at the tape? The open core tips (underside of the eraser) should be as close to the tape as possible. The field is shallow and you want it to penetrate the full wodth of the tape.

What counts is what sounds best to your ears. The thing to do is get a selection – if you can – and listen to them, and decide which YOU like best, not what anyone else tells you is best. That said, avoid “newer” European TDK made SA’s – they have tendency to drop out and their shells are poor such that, if you use a deck with manual azi’ adjust , like a ZX9/7, it’s usual (in my experience) to have to readjust the azi setting for each side of the cassette. You don’t have to do that with the old Japanese made TDK SAs and many other brands. I am also told the SA’s made in Mexico were good, too – certainly better than those from Europe.

I had the problem refered to and thought it was a fault with my de-gausser , which I use mainly to erase 2" tape.  The design of the machine is such that, you push the tape through a gate which switches on the field, when you remove, the gate closes and the field collapses, but the tape is still marginally under the coils.  I will adapt my method in the future to that explained in the article.  I will also now erase cassettes before re-recording, rather than rely on the function of the erase head.  Thanks to Ron who explained the advantage of this method.

I think degaussing leaves the tape totally random, if done right. An eraser that achievs full penetration, pulled off very slowly, can achieve an ultimate result. I don't know the status of out-of- the-box tape, but even if degaussed at the factory (which I doubt) it can become magnetized on the way to the consumer. -- Ron > > > > > At 02:10 AM 11/30/2009, you wrote: > > Both using a > degausser and > running the tape through a deck set in record mode will try > to return the > oxide molecules on the tape to a random state.  The > erase head is > only capable of dealing the two channels it is addressing > and its depth > of erasure is not as good as a bulk degausser.  Using > the re-record > process will always leave small traces of the original > waveforms which > were recorded on the tape and will consequently cause small > amounts of > intermodulation distortion in the fresh recording.  > Bulk degaussing > a tape is always a preferable method but it does not allow > you to save > any of the original recording so if you wish to reuse one > side of the > tape you have no choice but to use the erase head.  > > > Willy > > > On Sun, Nov 29, 2009 at 2:25 PM, Roland > > wrote: > > > > Okay, I've a dumb question.  Why are > degaussers necessary when > an erase head does the same job?  Or am I mistaken > that they do the > same job?  Just curious. > > > > > > At 03:45 PM 11/29/2009, you wrote: > > > > The Geneva PF250 is strong enough (3000 gauss) to erase > metal tapes, > and used ones > > > occasionally show up on eBay.

As the are particles of magnetic material like Fe, we can say the are always magnetic. In a small field and only in chaotic way. Because the small particles are in no order there is no magnetic field with any direction on the tape. If a screwdriver keeps a screw with his magnetic field, this field goes in one direction. Still this tapes collect the dust from the room. The high frequencies from the bias ozillator through the record head ( not the same frequencies from the music )does order the particles. With the time the tape loses a bit of this order, even with contact to magnetic parts of the Deck, like Capstan shafts or playback heads with very little magnetic field does earase the order of the particle. fascinating, and still we can hear so much on this small tapes! regards Am 02.12.2009 um 04:14 schrieb Roland: > As far I know, neither.

Kermit Gray, Ron et al. It got pretty ugly, but some good info was given out on degaussing. To get a good degauss, the unit needs to put out at least 3000 Gauss. The bigger the transformer, the longer it can stay on without shutting off. That's why those older, heavy units seem to bring more money on ebay most of the time. If you can find one of those larger unit with a built in tray, you've got a real item. I have a big heavy unit I use for R2R tape, but have never tried it for cassette. It actually improves the background noise on new R2R tapes and the pros recommend degaussing even new tape before they record. I have an old, hand held Radio Shack model that I used for cassettes. However, it shuts off when it gets 'hot' and requires multiple passes for metal tape. It works, it's just a pain. The good news is that if you find one of the older heavier unit, they usually require nothing more than a new cord in their lifetimes...unless they've been dropped off a building, run over etc. As Kermit wisely said, if they're humming, they're working.;-) Kevin Message: 18 Date: Wed, 2 Dec 2009 09:32:03 +0100 From: "Wouter Heijke" Subject: Re: [naktalk] Tape degausser To: "Talk about Nakamichi Cassette Decks" Message-ID: <2010ab5e75d93f90e3ae3342069dc36b.squirrel at webmail.xs4all.nl> Content-Type: text/plain;charset=iso-8859-1 Picked up the same one yesterday on Ebay: > > Please see (mine is the one they're asking > $29.95 for): > It will be waiting for me in NJ when I arrive there soon for the Christmas holidays with the family.

It now responds fine to all button functions, recording & playing back fine [in fact really good sound !!!] BUT although fast reverse works Ok fast fwd is still non operational so was looking for some pointers from the experts. Have checked in the SM & fast fwd is controlled by a 15V signal [like the reverse which works] plus the switching of Q401. I have examined but not tested [unsure how to do this] the pinouts for Q401 to see if there is evidence [burning or ?] of a component failure but there is none. Either this or the switch itself is all that I can think of. Are there any other areas I should also check out .

As a non-techie, but long experienced audio professional and tape enthusiast, I'll offer my 2 cents, and I'm sure our more tech-savvy NakTalkers will amplify. I think - theoretically - if the CR-7's (or any machine's) bias circuitry is clean and well adjusted, with most of the material we record, the audible difference between pre-record de-gaussing and letting the tape deck do the job on virgin tape is one that would not jump out at you, especially as, one assumes, you are using Dolby-C. Having said this - and getting back to theory... In addition to my Nak decks, I have a superb, built like a tank, high end Aiwa, the XK-S9000. The "S" signifies Dolby-S, the most highly developed consumer NR system Dolby Labs devised. A deck had to be of exceptional build and design for Dolby to license the process. As part of their absolute high-end statement for getting the most out of cassette, at a time when it was considered by many to be entering its twilight phase, Aiwa included a record mode that disabled the erase circuitry and head. It was designed for recording on virgin tape ONLY (for obvious reasons!) and the theory was that conventional bias did add "some" noise in the erase process. My suggestion with your CR-7, which of course does not allow front panel disabling of erase current is to do the following: 1. Unwrap two of your virgin TDK tapes. 2. Record the highest quality music, either with pauses in the music, as between notes, or just the silence between tracks on a CD, on one tape. 3. (Assuming you own a de-gausser) carefully degauss the second virgin tape, making sure you follow the directions given elsewhere, especially in terms of slowly pulling the unit away from the tape before turning off its power. 4. Listen to those quiet passages for any difference between the tapes. My guess is that any improvement wrought by hand demagnetizing prior to recording will be made moot by whatever minor amount of bias noise your CR-7 lays down on the tape. If the deck is functioning properly, this "added noise" - especially using Dolby C will be so vanishingly low as to be a non-issue.

I am talking about TDK-MA tapes and a CR7. Thanks.

In addition all of the belts have been changed apart from the capstan one [orig or replacement Nak one with the arrows]as I dont yet have a quality replacement available & the deck is now playing really well anyway. It now responds fine to all button functions, recording & playing back fine [in fact really good sound !!!] BUT although fast reverse works Ok fast fwd is still non operational so was looking for some pointers from the experts. Have checked in the SM & fast fwd is controlled by a 15V signal [like the reverse which works] plus the switching of Q401. I have examined but not tested [unsure how to do this] the pinouts for Q401 to see if there is evidence [burning or ?] of a component failure but there is none. Either this or the switch itself is all that I can think of. Are there any other areas I should also check out  . Thanks Dave Have more than one Hotmail account?

I think - theoretically - if the CR-7's (or any machine's) bias circuitry  is clean and well adjusted, with most of the material we record, the audible difference between pre-record de-gaussing and letting the tape deck do the job on virgin tape is one that would not jump out at you, especially as, one assumes, you are using Dolby-C. Having said this - and getting back to theory... In addition to my Nak decks, I have a superb, built like a tank, high end Aiwa, the XK-S9000.  The "S" signifies Dolby-S, the most highly developed consumer NR system Dolby Labs devised.  A deck had to be of exceptional build and design for Dolby to license the process.  As part of their absolute high-end statement for getting the most out of cassette, at a time when it was considered by many to be entering its twilight phase, Aiwa included a record mode that disabled the erase circuitry and head.  It was designed for recording on virgin tape ONLY (for obvious reasons!) and the theory was that conventional bias did add "some" noise in the erase process. My suggestion with your CR-7, which of course does not allow front panel disabling of erase current is to do the following: 1. Unwrap two of your virgin TDK tapes. 2. Record the highest quality music, either with pauses in the music, as between notes, or just the silence between tracks on a CD, on one tape. 3. (Assuming you own a de-gausser) carefully degauss the second virgin tape, making sure you follow the directions given elsewhere, especially in terms of slowly pulling the unit away from the tape before turning off its power. 4. Listen to those quiet passages for any difference between the tapes. My guess is that any improvement wrought by hand demagnetizing prior to recording will be made moot by whatever minor amount of bias noise your CR-7 lays down on the tape.  If the deck is functioning properly, this "added noise" - especially using Dolby C will be so vanishingly low as to be a non-issue.

The issue is residual noise of reused tape, which I found bulk erasure did reduce.

My feeling is there is no benefit in running VIRGIN tapes through de-gaussing, which was Jayson's question -- see below. Obviously, there IS a benefit to - carefully - demagging previously used tapes, ESPECIALLY those made on another deck to eliminate any issues of non-standard head height, tape path, etc., which COULD cause some "rumbly" artifacts during quiet passages in the music in the newly made recording. I'd also suggest, as Ron mentions, that - once again - careful de-magging is a safeguard, should one have any doubts regarding his machine's ability to fully erase especially high coercivity tapes Cheers, and Good Holiday Wishes to All!

Take the same tape and properly degauss it with the machines as discussed. Put the tape back in, turn up the gain again and listen...simple. On new R2R tape, the difference in background noise is remarkable and I would expect the same results in metal cassettes. As I said earlier, any degauss machine that puts out 3000 Gauss of more, should work fine. Kermit has some old machine called 'Old Girl' of something kitchen-isk like that and it works on everything. I have an old beast called the Lafayette Model ML-120 that seems to work fine on everything that I've tried so far.....just haven't done cassettes on it yet. The transformer is so massive that I've never seen it 'click off' yet or get more than warm. The high Gauss models with a drawer would be ideal...they usually run too high on ebay for my budget....and then there's the shipping of heavy stuff these days.

This is an inexpensive part that should be available without great difficulty these days. Looking at your SM, check where the FFWD switch is connected to. It should be connected to a pair of NOR gates (the pointy leaf shape) that are connected in a latch configuration. The output from these gates usually leads to a comparator. Check to see that a 12 volt is present at the input of the comparator from the moment the FFWD button is pressed until the stop button is pressed, which should cut-off the 12 volts to the comparator. If so far it looks good, then from the comparator, you have a pair of switching transistors which you say looks alright. But if they are very hot without the motor running, then it's the transistor. I have seen the transistor failing a number of times, and the logic ic failing a few times. But this is an easy problem to fix. Also, a lot of people think that running the transport with a low voltage source is good, but there are a couple of points to note: 1. Disconnect the motor leads from the circuit. Otherwise you will be also feeding voltage back to the circuit. The circuit is designed to take a small amount of back EMF from the motor but this is one common think to look over. 2. Ensuring that the mechanism operates on low voltage is not enough - the older mechanism is incredible tolerant and will work smoothly without complaining. But, it is very important to check for dried or sticky lubrication, alignment (the positioning of the cam pointer at various modes), and listen to the sound of the mechanism. This is best heard only at the actual drive voltage. Ideally, the sound should be a very smooth and near silent sound and the transport should actuate quickly. There are many knowledgeable guys here and I am sure you will pick up more advice when you shout for it. Good Luck.

Sounds like dead spots that contact cleaners (deoxit or others) may (or may not) temporarily cure -- but not for long. You can try to rebuild the motor, but (based on my experience with Mabuchi motors used in Sankyo transports) this has a limited success rate. If the reel motor continues to intermittently stall during play, for no apparent reason, replacing it may be the best approach. > - now however the deck is halting due to what can only be > described as haphazard functioning of the control motor > [moving selector regardless of mode selected] I have never seen a control motor that moves of it's own volition. I would suspect the motor control/driver electronics. > Any idea if this is symptomatic of something else eg orange > cap disease in the circuitry or completely faulty control > motor/control board therein or ??? Neither of these is very common on classic transport decks such as the 480/580 series. I doubt either fault is caused by caps, but in love, war and Nakamichi decks, anything is possible. -- Ron > > Anyone else [?Andy ?] experienced this > > Thanks dave > > > > Date: Thu, 3 Dec 2009 04:42:42 -0800 > From: wbendler at sbcglobal.net > Subject: Re: [naktalk] Help with 480 please > To: naktalk at naks.com > > Does the reel motor turn when you push fast > forward, do you hear something, or does nothing happen?

This is an inexpensive part that should be available without great difficulty these days. Looking at your SM, check where the FFWD switch is connected to. It should be connected to a pair of NOR gates (the pointy leaf shape) that are connected in a latch configuration. The output from these gates usually leads to a comparator. Check to see that a 12 volt is present at the input of the comparator from the moment the FFWD button is pressed until the stop button is pressed, which should cut-off the 12 volts to the comparator. If so far it looks good, then from the comparator, you have a pair of switching transistors which you say looks alright. But if they are very hot without the motor running, then it's the transistor. I have seen the transistor failing a number of times, and the logic ic failing a few times. But this is an easy problem to fix. Also, a lot of people think that running the transport with a low voltage source is good, but there are a couple of points to note: 1. Disconnect the motor leads from the circuit. Otherwise you will be also feeding voltage back to the circuit. The circuit is designed to take a small amount of back EMF from the motor but this is one common think to look over. 2. Ensuring that the mechanism operates on low voltage is not enough - the older mechanism is incredible tolerant and will work smoothly without complaining. But, it is very important to check for dried or sticky lubrication, alignment (the positioning of the cam pointer at various modes), and listen to the sound of the mechanism. This is best heard only at the actual drive voltage. Ideally, the sound should be a very smooth and near silent sound and the transport should actuate quickly. There are many knowledgeable guys here and I am sure you will pick up more advice when you shout for it. Good Luck.

Sounds like dead spots that contact cleaners (deoxit or others) may (or may not) temporarily cure -- but not for long. You can try to rebuild the motor, but (based on my experience with Mabuchi motors used in Sankyo transports) this has a limited success rate. If the reel motor continues to intermittently stall during play, for no apparent reason, replacing it may be the best approach. > - now however the deck is halting due to what can only be > described as haphazard functioning of the control motor > [moving selector regardless of mode selected] I have never seen a control motor that moves of it's own volition. I would suspect the motor control/driver electronics.   > Any idea if this is symptomatic of something else eg orange > cap disease in the circuitry or completely faulty control > motor/control board therein or ??? Neither of these is very common on classic transport decks such as the 480/580 series. I doubt either fault is caused by caps, but in love, war and Nakamichi decks, anything is possible. -- Ron > > Anyone else [?Andy ?] experienced this > > Thanks dave > > > > Date: Thu, 3 Dec 2009 04:42:42 -0800 > From: wbendler at sbcglobal.net > Subject: Re: [naktalk] Help with 480 please > To: naktalk at naks.com > > Does the reel motor turn when you push fast > forward, do you hear something, or does nothing happen?

That's not surprising, as demagnetizing does not improve sonics. It merely prevents deterioration that will be caused by magnetized heads in the future. In forty years of owning and servicing tape recording equipment, I have been demagnetizing heads more or less on a regular basis. I can't argue that it was really necessary, as I don't know how tapes would sound today had I not done it. But I feel it's better to demagnetize, even though it's not necessary, then lose high frequencies on tapes because it was necessary, but not done. And, by the way, every manufacturer of every piece of recording equipment I have ever owned stressed the need. for regular demagnetizing. This included Grundig, Uher, ReVox, Ferrograph (?), Tandberg and (last, but not least) Nakamichi. -- Ron --- On Sat, 12/5/09, paul williams wrote: > From: paul williams > Subject: Re: [naktalk] RE:Tape degausser > To: "Talk about Nakamichi Cassette Decks" > Date: Saturday, December 5, 2009, 5:20 AM > > In my forty years of servicing > electronic equipment, I have never found it neccessary to > de-magnetize heads.  CRTs yes, but never heads. > I wonder what others here have found? > Paul > > --- On Fri, 4/12/09, Kevin Fetner > wrote: > > > From: Kevin Fetner > Subject: [naktalk] RE:Tape degausser > To: naktalk at naks.com > Date: Friday, 4 December, 2009, 16:52 > > Come to think of it you're > actually correct, as it did start out about tape head > demag-ing.

This is an inexpensive part that should be available without great difficulty these days. Looking at your SM, check where the FFWD switch is connected to. It should be connected to a pair of NOR gates (the pointy leaf shape) that are connected in a latch configuration. The output from these gates usually leads to a comparator. Check to see that a 12 volt is present at the input of the comparator from the moment the FFWD button is pressed until the stop button is pressed, which should cut-off the 12 volts to the comparator. > >If so far it looks good, then from the comparator, you have a pair of switching transistors which you say looks alright.

But this is an easy problem to fix. Also, a lot of people think that running the transport with a low voltage source is good, but there are a couple of points to note: > >1. Disconnect the motor leads from the circuit. Otherwise you will be also feeding voltage back to the circuit.

Ensuring that the mechanism operates on low voltage is not enough - the older mechanism is incredible tolerant and will work smoothly without complaining. But, it is very important to check for dried or sticky lubrication, alignment (the positioning of the cam pointer at various modes), and listen to the sound of the mechanism. This is best heard only at the actual drive voltage. Ideally, the sound should be a very smooth and near silent sound and the transport should actuate quickly. > >There are many knowledgeable guys here and I am sure you will pick up more advice when you shout for it.

I cleaned the heads, and no change. I demagnetised the heads and the distortion vanished. The same happened a couple of times more over a few years times more with my deck (and old top-loading Aiwa AD1800, which I still have but it's not working) and also with a cassette machine in a car. I wondered if that may have been caused by the tape "sticking" to the heads in their magnetised state. Am I being as daft as a brush? From: naktalk-bounces at naks.com [mailto:naktalk-bounces at naks.com] On Behalf Of Ron Sent: Sunday, December 06, 2009 1:16 AM To: Talk about Nakamichi Cassette Decks Subject: Re: [naktalk] RE:Tape degausser Some people argue that demagnetizing heads is not necessary, because they can't hear any difference after demagnetizing. That's not surprising, as demagnetizing does not improve sonics. It merely prevents deterioration that will be caused by magnetized heads in the future. In forty years of owning and servicing tape recording equipment, I have been demagnetizing heads more or less on a regular basis. I can't argue that it was really necessary, as I don't know how tapes would sound today had I not done it. But I feel it's better to demagnetize, even though it's not necessary, then lose high frequencies on tapes because it was necessary, but not done. And, by the way, every manufacturer of every piece of recording equipment I have ever owned stressed the need. for regular demagnetizing. This included Grundig, Uher, ReVox, Ferrograph (?), Tandberg and (last, but not least) Nakamichi. -- Ron --- On Sat, 12/5/09, paul williams wrote: > From: paul williams > Subject: Re: [naktalk] RE:Tape degausser > To: "Talk about Nakamichi Cassette Decks" > Date: Saturday, December 5, 2009, 5:20 AM > > In my forty years of servicing > electronic equipment, I have never found it neccessary to > de-magnetize heads.

If so, the problem is mechanical -- usually, slippage in the pulley to idler to hub linkage, hub friction or back tension issue. Should be easy to diagnose by just looking. If the motor doesn't run, the problem is probably electrical. {Possibly, the motor driver circuit. Whether the repair is easy is up to you.

This is an inexpensive part that should be available without great difficulty these days. Looking at your SM, check where the FFWD switch is connected to. It should be connected to a pair of NOR gates (the pointy leaf shape) that are connected in a latch configuration. The output from these gates usually leads to a comparator. Check to see that a 12 volt is present at the input of the comparator from the moment the FFWD button is pressed until the stop button is pressed, which should cut-off the 12 volts to the comparator. If so far it looks good, then from the comparator, you have a pair of switching transistors which you say looks alright. But if they are very hot without the motor running, then it's the transistor. I have seen the transistor failing a number of times, and the logic ic failing a few times. But this is an easy problem to fix. Also, a lot of people think that running the transport with a low voltage source is good, but there are a couple of points to note: 1. Disconnect the motor leads from the circuit. Otherwise you will be also feeding voltage back to the circuit. The circuit is designed to take a small amount of back EMF from the motor but this is one common think to look over. 2. Ensuring that the mechanism operates on low voltage is not enough - the older mechanism is incredible tolerant and will work smoothly without complaining. But, it is very important to check for dried or sticky lubrication, alignment (the positioning of the cam pointer at various modes), and listen to the sound of the mechanism. This is best heard only at the actual drive voltage. Ideally, the sound should be a very smooth and near silent sound and the transport should actuate quickly. There are many knowledgeable guys here and I am sure you will pick up more advice when you shout for it. Good Luck.

It now responds fine to all button functions, recording & playing back fine [in fact really good sound !!!] BUT although fast reverse works Ok fast fwd is still non operational so was looking for some pointers from the experts. Have checked in the SM & fast fwd is controlled by a 15V signal [like the reverse which works] plus ��the switching of Q401. I have examined but not tested [unsure how to do this] the pinouts for Q401 to see if there is evidence [burning or ?] of a component failure but there is none.

Sounds like dead spots that contact cleaners (deoxit or others) may (or may not) temporarily cure -- but not for long. You can try to rebuild the motor, but (based on my experience with Mabuchi motors used in Sankyo transports) this has a limited success rate. If the reel motor continues to intermittently stall during play, for no apparent reason, replacing it may be the best approach. > - now however the deck is halting due to what can only be > described as haphazard functioning of the control motor > [moving selector regardless of mode selected] I have never seen a control motor that moves of it's own volition. I would suspect the motor control/driver electronics. �� > Any idea if this is symptomatic of something else eg orange > cap disease in the circuitry or completely faulty control > motor/control board therein or ??? Neither of these is very common on classic transport decks such as the 480/580 series. I doubt either fault is caused by caps, but in love, war and Nakamichi decks, anything is possible. -- Ron > > Anyone else [?Andy ?] experienced this > > Thanks dave > > > > Date: Thu, 3 Dec 2009 04:42:42 -0800 > From: wbendler at sbcglobal.net > Subject: Re: [naktalk] Help with 480 please > To: naktalk at naks.com > > Does the reel motor turn when you push fast > forward, do you hear something, or does nothing happen?

That's not surprising, as demagnetizing does not improve sonics. It merely prevents deterioration that will be caused by magnetized heads in the future. In forty years of owning and servicing tape recording equipment, I have been demagnetizing heads more or less on a regular basis. I can't argue that it was really necessary, as I don't know how tapes would sound today had I not done it. But I feel it's better to demagnetize, even though it's not necessary, then lose high frequencies on tapes because it was necessary, but not done. And, by the way, every manufacturer of every piece of recording equipment I have ever owned stressed the need. for regular demagnetizing. This included Grundig, Uher, ReVox, Ferrograph (?), Tandberg and (last, but not least) Nakamichi. -- Ron --- On Sat, 12/5/09, paul williams wrote: > From: paul williams > Subject: Re: [naktalk] RE:Tape degausser > To: "Talk about Nakamichi Cassette Decks" > Date: Saturday, December 5, 2009, 5:20 AM > > In my forty years of servicing > electronic equipment, I have never found it neccessary to > de-magnetize heads.� CRTs yes, but never heads. > I wonder what others here have found? > Paul > > --- On Fri, 4/12/09, Kevin Fetner > wrote: > > > From: Kevin Fetner > Subject: [naktalk] RE:Tape degausser > To: naktalk at naks.com > Date: Friday, 4 December, 2009, 16:52 > > Come to think of it you're > actually correct, as it did start out about tape head > demag-ing.

This is an inexpensive part that should be available without great difficulty these days. Looking at your SM, check where the FFWD switch is connected to. It should be connected to a pair of NOR gates (the pointy leaf shape) that are connected in a latch configuration. The output from these gates usually leads to a comparator. Check to see that a 12 volt is present at the input of the comparator from the moment the FFWD button is pressed until the stop button is pressed, which should cut-off the 12 volts to the comparator. > >If so far it looks good, then from the comparator, you have a pair of switching transistors which you say looks alright. But if they are very hot without the motor running, then it's the transistor. > >I have seen the transistor failing a number of times, and the logic ic failing a few times. But this is an easy problem to fix. Also, a lot of people think that running the transport with a low voltage source is good, but there are a couple of points to note: > >1. Disconnect the motor leads from the circuit. Otherwise you will be also feeding voltage back to the circuit. The circuit is designed to take a small amount of back EMF from the motor but this is one common think to look over. > >2. Ensuring that the mechanism operates on low voltage is not enough - the older mechanism is incredible tolerant and will work smoothly without complaining. But, it is very important to check for dried or sticky lubrication, alignment (the positioning of the cam pointer at various modes), and listen to the sound of the mechanism. This is best heard only at the actual drive voltage. Ideally, the sound should be a very smooth and near silent sound and the transport should actuate quickly. > >There are many knowledgeable guys here and I am sure you will pick up more advice when you shout for it.

This is an inexpensive part that should be available without great difficulty these days. Looking at your SM, check where the FFWD switch is connected to. It should be connected to a pair of NOR gates (the pointy leaf shape) that are connected in a latch configuration. The output from these gates usually leads to a comparator. Check to see that a 12 volt is present at the input of the comparator from the moment the FFWD button is pressed until the stop button is pressed, which should cut-off the 12 volts to the comparator. > >If so far it looks good, then from the comparator, you have a pair of switching transistors which you say looks alright.

But this is an easy problem to fix. Also, a lot of people think that running the transport with a low voltage source is good, but there are a couple of points to note: > >1. Disconnect the motor leads from the circuit. Otherwise you will be also feeding voltage back to the circuit.

Ensuring that the mechanism operates on low voltage is not enough - the older mechanism is incredible tolerant and will work smoothly without complaining. But, it is very important to check for dried or sticky lubrication, alignment (the positioning of the cam pointer at various modes), and listen to the sound of the mechanism. This is best heard only at the actual drive voltage. Ideally, the sound should be a very smooth and near silent sound and the transport should actuate quickly. > >There are many knowledgeable guys here and I am sure you will pick up more advice when you shout for it.

In forty years of owning and servicing tape recording equipment, I have been demagnetizing heads more or less on a regular basis. I can't argue that it was really necessary, as I don't know how tapes would sound today had I not done it.

If the 12V bidirectional regulator is faulty, and it's output is varying or noisy, you can get erratic operation of the control motor and reel motor circuits. The 12V bidirectional regulator consists of transistors Q407, Q408, half of IC402, R425, R426, C408, and R424. Measure the voltage at the emitters of Q407 and Q408. This should be a stable 12V DC. If it varies when the deck is simply in the stop mode, this could easily explain your decks behaviour. Also check the 24V supply (you could check this at the collector of Q407) - the 12V supply is derived from the 24V supply (and is half of the voltage - so if the 24V supply is out, so will be the 12V supply). I checked through my repair database and found that the most common defective parts for this fault were IC402, and Q407. A few instances of Q408, and one instance of C408 (not an orange cap, but a ceramic) had also occurred. I have also had instances of the 24V regulator failing, but the symptoms you describe fit the 12V bidirectional supply. If you don't have electronic troubleshooting ability, and if the 12V is unstable, start by replacing IC402. Hope this helps, and good luck. Regards John Gipps From: Dave Bowley Subject: RE: [naktalk] Help with 480 please To: "Talk about Nakamichi Cassette Decks" Date: Friday, December 4, 2009, 10:15 AM Thanks for the feedback Warren. Unfortunately from a relatively good position with only the one issue the reliability has now plummetted - was playing the deck, as one does, to give it a few more miles [post Deoxit] & it stopped. Managed to resuccitate it again with a 12V battery attack on the reel motor [again] followed by again a period of normality. - now however the deck is halting due to what can only be described as haphazard functioning of the control motor [moving selector regardless of mode selected] Any idea if this is symptomatic of something else eg orange cap disease in the circuitry or completely faulty control motor/control board therein or ??? Anyone else [?Andy ?] experienced this Thanks dave _________________________________________________________________ Have more than one Hotmail account?

So, I hope Im doing this right. I have literature from Annis from the mid 1980's regarding the R.B. Annis Han-D-Mag,its in with my mass of literature from various Manufacturers of Audio Gear, and Tools, in the age prior to the Internet. I have been into this stuff for years, and only got into the Internet part in the early to mid 1990's. But it was mainly DOS then, and Prodigy, before AOL. Anyhow, the Annis demagnetizer is a Dual Purpose tool, and a very good one at that. The Butt End is designed for use as a bulk eraser for audio tapes, reel to reel and cassette. I have had no problems with the Annis erasing either format. The only one I ever had to redo, was Metal Reels of 10" Reel to Reel tapes, due to the thick Aluminum Flanges that hold the tape, but plastic reels and cassette were never a problem for me. As for Bulk Erasers, The very Large and Powerful ones, that have a drawer, or conveyor belt, cost thousands of dollars and are way too much overkill for my purposes. I do own several Handheld Bulk Tape Erasers. I have 2 from Radio Shack, a smaller one, and their Largest most powerful one, its very large and heavy, but sucks in my opinion. The Others I own are Robbins Gibson Girl, which may be what Kermit was referring to as well, its an older unit, but I dont have the Literature that came with it, but its very heavy, and built much better than the Radio Shack Erasers. I also have a Nortronics and a Geneva Handheld, these look similar to oneanother. And both of these have no problems erasing. The Most Powerful Unit I own, in my Opinion, is a Large Flat TEAC/TASCAM Eraser, which is not handheld, its a Large Rectangular Tabletop Eraser, made more specific for Reel to Reel Tapes, up to at least 10 Inch Reels of Tape. This was expensive, bought new, and very heavy. It will also do Cassettes, but I never use them on it really, due to fact that the Annis works very well on these, as do the Gibson Girl, and Geneva and Nortronics. I have erased Metal Type Cassette Tapes, but cant remember if I used the Annis or my other Handhelds. I did erase Metal Reel to Reel Tapes, which were called "EE" Tapes, made by Maxell, TDK, AKAI, FUJI, and I think Sony, not sure. But even these, I seldom ever used, because although they sounded great, so do my other newer Reels of Higher Bias Tapes, by Quantegy, and others. I have also read that the Metal EE tapes do much wear on the Heads of Various Machines, though not my AKAI GX Heads, they handle just about anything thrown at them. I have a Nakamichi RX-505, and also a Tandberg TCD-3014A....and I honestly get such great recordings from TDK SA, to TDK SA-X Chrome Bias Tapes, that I have only used Metal Tapes for certain Special Recordings, and have not had the need to Erase any of these Tapes. So, I rarely have ever erased any Metal Tapes. But all others have erased with no problems with the Annis Demag. And the Literature that I have, which was much longer and more detailed, from years ago, told all about using the Butt End of the Demag for Bulk Tape Erasing. That is how I knew about it, and I knew this from Annis themselves, through Literature and Phonecalls from the 1980's. I have also read about this in Professional Recordist Magazines, where the Musicians that do recording, spoke about the Annis being the Only Demagnetizer to own, and how they used the Butt Ens as well for erasing. SO none of this was surprising to me, and I have 2 Annis Han-D-Mags. When I locate the Original Literature, I will Scan the pages, and then email them to you, so it would be good if you email me your address. And when I find this, I will send it to you. Its a great unit, with great customer support, they also make Giant Demagnetizers for use of things other than Audio Tape Heads, etc... Magnetism has been their Field of work as long as they have been around, which is alot of years, and American Made....They remind me of the concept of Zippo Lighters.

Of course they also sell their magnetometers which are very useful to have, and in their site they have a set which contains everything you need as far as de-mag process concerns for our decks and not only.....At the time i contacted them they were out of the long probe hand D Mag (!) but i presume it should not be a problem any more.....In any case i would not recommend this unit to bulk erase metal bias tapes, it just doesnt work! Only for normal bias tapes and will take too much time..... Hope this helps As for the bulk tape eraser i agree with Jayson the best way to go is with the PF-215 which is powerful enough for metal tapes. I use this with no problems over a year.....

Hi Ray, As far as I have owned and read there were no metal( meaning metal bias ) EE rtr tapes ever made by anyone.None. Period. All EE rtr tapes were made by Maxell, Sony, Akai, Teac, TDK and these were all akin to the TDK SA/Maxell XLII type II tapes. None for rtr were ever metal or metal alloy tapes.  All were cobalt adsorbed ferrite( type II as in cassette type designation) I hope you did not use the word metal for metal reels!

I'm sure it will work with repeated passses or given enough time. My old Radio Shack bulk eraser works on metal cassettes...given enough passes and waiting for it to cool down and cycle again. The argument was whether or not the Han D Mag was purpose built for this function..... OR are there better units built for bulk erasing tapes. There are of course and with more Gauss output. Contrary to what was said, the table units are not that expensive (if older) and even the drawer units I've seen go on ebay for under $100. True that typically, many drawer units sold new for thousands, but they went out the door along with magnetic tape. They still design/make really expensive units to wipe hard drives etc for security purposes, that have even multiple drawers. The Geneva model you mention is really close to Kermit Gray's 3000 Gauss minimum limit (although he said 5,000 Gauss was better). Pretty powerful for a hand-held unit!

I also have a Han-D-Mag and just spoke to Sylvia Scott at R.B. Annis. The probe end has 720 Gauss, and the butt end is more powerful at 1,100 Gauss. From what I have been reading, this is still not enough to completely erase metal cassette tapes. The Geneva Audio / Video Tape Eraser PF 215 has 2,800, and I believe this is the most powerful handheld degausser currently available.

I like to share what I have been told, or learned. I really dont erase Metal tapes, as I was saying. As for the EE Tapes, which are Reel to Reel tapes, I have 2 machines which are capable of use with EE Tapes, not all machines had this ability. However, everything I have read stated that they are very abrasive on the Heads, and I chose to only use the couple of these tapes that I own. Yes, the Metal I am referring to, Reel to Reel Tapes. They come in both Metal Flanges and Plastic Reels. The Metal Flanges I believe somehow get in the way of erasing, and need extra passes to erase. Many people with Reel to Reels claim that you cannot fully erase EE tapes due to their formulation, but I have not had any problems erasing them, when I did try it, just to see if this was true. They erased just like any other tape for me, no issues. But yeah, the Metal Flanges can be a problem, I sometimes unscrew the Flanges, and then do the erasing. Its pretty easy. As for the Reel to Reels, I use the Quantegy 457 very often, and also the BASF Tapes, and GP9 by Quantegy these are high bias tapes, +9 and +12 which sound far better than the EE tapes of old. But many Reelers dont believe this, and they pay hundreds of dollars for NOS EE Tapes, its crazy. I heard the same things about Metal Cassette tapes not erasing, like the EE tapes, but I can do both with no issues.

But remember the Annis Han-D-Mag is a REAL Demagnetizer, and you dont have to get right on top of everything. Getting very close is goood enough. Plenty of power in these. And claims of 5000 Gaus, in my opinion is overkill. A good capable handheld is sufficient for most people. I have enough new cassettes, still wrapped to last me longer than any of the recording on cassette I intend to be doing in my lifetime. I have cases of TDK SA, and SA-X and Metals, that I bought out from a guy with a Record/CD store, closeout, great deal. But I dont make a habit of Erasing Tapes on a regular basis. And I would think that even my Powerful Tabletop TEAC/TASCAM is 5000 gaus, and has yet to meet atape it cant erase. Same with my handhelds. You will do fine with the Geneva Handheld your looking at. Radio Shack is junk, they are the 2 units, that I dont ever touch. And I even have their Large Heavy Duty one. They just dont compare to the Gibson Girl, or Geneva, etc...especially the TEAC/TASCAM. I find that if Im Demagging, and I want to erase a tape, I end up just grabbing the Han-D-Mag and erase it, without a problem. If all you have is a boatload of used cassette tapes, and need to erase them all, then you may want to buy a drawer, or multi drawer type, but otherwise, its overkill. IMHO.....Best Regards, Ray -------------- next part -------------- An HTML attachment was scrubbed...

Message-ID: <352D536D-BC7F-432D-A787-A4A2DC1E18E9@verizon.net> Hello, I am a new member, and was wondering if anybody here could help me repair my ZX7. It was working great until last week, when it started losing sound in one output channel (input was working OK). Thinking that it may be just a loose contact, I removed the cover and sprayed some RS contact spray inside. This did not help. However, couple of hours after that the deck stopped responding to play, ff and rew buttons. When play button is pressed, tape does not move at all, and heads move up but come back down after a second or two. FF and REW functions do not work at all. Thinking that auto stop lamp has failed, i removed the front cover, but the lamp is OK. All the belts and idler tire are in place and in good shape. I measured the voltage at the motor that runs the idler wheel, and when play button is pressed the voltage goes up a notch, to about 4-5 volts, but it is hard to tell the exact value because it switches off immediately when heads drop down. By the way, the original problem of lost output in one channel was located to the broken wire in the RCA female jack. I can easily fix that, but am at loss how to fix other issues. I would be very grateful if any of the Nakamichi experts here could help me with advice.

I asked this once before, but as we are still having the same problem, I thought I would post it again, with updates. My tech is almost done with my 681ZX, but one thing has him beat.

They will leave for the night, figuring they have it beat, only to return to a unit that is not working the following day. Sometime it will work for a couple of days, and then stop working. The think it is not heat related, as they tried that. They also replaced most of the related caps and transistors, and still they can't get it working. They are not new to Naks, having been their warranty repair shop for 2 decades now, and have worked on a number of these. They probably have a weeks work into it, but to no avail.

I have myself used his belts for 3 1000ZXl's that I serviced recently.   However I have also converted one ZX 9 motor with Dragon DD motor as well. 1000ZXL needs more than anything complete Orange cap replacement and alignment much more than Direct Drive motor.   kannan --- On Thu, 12/17/09, cmpsalvestrini at vodafone.pt wrote: From: cmpsalvestrini at vodafone.pt Subject: [naktalk] Some doubts and/or uncertainties To: naktalk at naks.com Date: Thursday, December 17, 2009, 9:34 AM With the coming of the holiday season I was thinking about overhauling my 1000ZXL to bring it to its pristine glory (I fear Luis is going to be my service man, as he's the one closest to me - I live in Lisbon, and yes I'd be delivering it personally).

He has also successfully done a 1000ZXl from another member here( Ben) using the ZX9s capstan assembly and motor. My project was 100% successful and the deck is flawless since. However, there is no need to convert as Fred Marrs from www.marrscommunications.com does sell excellent belts and so does ESL labs in Ct in the USA. The DD option does reduce the wow and flutter considerably. Regards, and good luck.

I am in the process of refurbishing a beautiful NAK 670ZX in very good physical condition. Internally it seems untouched and all in original condition except for two missing polypropylene capacitors on the switch PCB numbered C119 and C219. The PCB holes for these caps show evidence of solder, so something was soldered in originally. The capacitors in question are in the equalisation circuit (70us position) and each sit in parallel with a 15K resister in their respective input channels. On the circuit, the RC pair are marked with an *, and a notation stating "Resister and capacitor marked with * show typical value". Is anyone aware of an equalisation modification that may have called for the removal of these matching 680p caps in the eq circuit or has someone removed these caps for some other reason?

My card was charged for an order I had never placed and I am not an identity theft victim. The charge was for more than $100, so it was serious enough! That made me not conduct any more business with them since 2006. And some sellers on ebay used my information( name and address) and started up websites( inwhich they stole thousands if not millions)and they were finally shut down after my complaint to the NYS attorney general.I learned of their fraud when a victim called my ebay contact number and complained to me! The site was www.goldpayprofits.com. So no cyberspace is 100%safe. Its upto us to be vigilant and see what we buy!...including bidding ( and shill bidding) on ebay! My 2 pennies...

A wired Dragon remote control sold for $299 + shipping (I received one along with my Dragon). Working in the engineering office and being associated with other office departments, I've learned that: 'Your product is only as good as it's advertised'. Think about it. Also - the fact that this was a worldwide auction and (I'm guessing) perhaps since the value of the American dollar has declined 'may' also had been a factor (no argument in politics please). In conclusion (my opinion), the seller of the BX-300 got lucky selling it at a ridiculous price.

In my circuit, C118/218 are AC coupling capacitors leading into the equaliser. C119/219 are part of an RC network sitting in parallel with R119/219. Figure 13.1 Amplifier...in the service manual which I downloaded from the Nak wiki. Perhaps a different serial number to your circuit??

A TON of differences between it and my #24XXX..sheesh. Anyway, anyone with a parts deck that they want to sell parts from? I need a rewind button, (double arrows facing left) just the plastic part that you press, the actual button works. Do any of the other Naks have the same rewind button? Also, by swapping boards between the non working one, and my good Dragon, I've determined that the motor control board is the reason the capstans don't turn. Both don't, so it appears something in common with both circuits. Is there a common component (IC, cap or transistor) that is prone to failure that both capstans share? All the caps test good on an ESR meter, and no opens or shorts. I'm hoping it's a 4066bc, as I have bunch of them I can swap out.

I did note the information on page 27, and could understand why you would want to peak up the record response, but short of some field bulletin that called for the removal of the standard caps, I couldn't for the life of me understand why someone would want to remove them. You have cleared up that possibility though, which only leaves as you say a deliberate dulling down of the response which does seem a bit strange. I will take your advice and fit new 680pF caps back in circuit, and when I finish re-belting etc, will preform a full alignment and see where the deck stands. Thanks again John --David ________________________________________ From: John Gipps [johngipps at ymail.com] Sent: 20 December 2009 18:15 To: David King; naktalk at naks.com Cc: johngipps at aol.com Subject: Technical Question re 670ZX (David King) Hi David If you have a service manual for your 670ZX, have a look at page 27. C119 and C219 are specified as 680pF, and another capacitor without designation can be placed in parallel with them to adjust record peaking. If C119 and C219 are present, but with no other capacitors in parallel, you have the minimum amount of record peaking specified by Nakamichi. If you put 330pF in parallel with each (a total of almost exactly 1nF each channel), you achieve 1dB more peaking in the 20KHz to 23KHz area. If you make it 680pF in parallel with each of C119 and C219 (a total of 1.36nF each channel), you achieve about 2dB more peaking in that 20-23KHz area. If someone has entirely removed C119 and C219, you will achieve less record peaking than Nakamichi specified. I haven't ever seen a bulletin from Nakamichi recommending this, but nothing surprises me these days. I did a search in my repair database, and no 670ZX or similar model ever presented to me with defective C119 or C219. Anyway, if a repairer found one of them to be defective, he or she would surely have replaced it. So the likelyhood is that someone removed those parts to slightly dull down the record response. Might be wise to install a 680pF cap in each location. I'd also like to take this opportunity to wish all NakTalk members a very happy Xmas and Festive Season.

I am in the process of refurbishing a beautiful NAK 670ZX in very good physical condition. Internally it seems untouched and all in original condition except for two missing polypropylene capacitors on the switch PCB numbered C119 and C219. The PCB holes for these caps show evidence of solder, so something was soldered in originally. The capacitors in question are in the equalisation circuit (70us position) and each sit in parallel with a 15K resister in their respective input channels. On the circuit, the RC pair are marked with an *, and a notation stating "Resister and capacitor marked with * show typical value". Is anyone aware of an equalisation modification that may have called for the removal of these matching 680p caps in the eq circuit or has someone removed these caps for some other reason? Thanks and Merry Christmas to all in the group. Regards David ________________________________ See what's on at the movies in your area. Find out now.

To test, turn the deck on with the cover off and press play. Even if the control cam moves, see if you can help it along just a bit further. If this cures the problem -- even though temporariliy -- then the control motor should be rebuilt or replaced. While at it, try to spray a drop of contact cleaner on  the three contacts actuated by the cam (this is less likely, but you never know). Beyond that, I would recommend enlisting a professional. Is it worth it? IMHO, yes. BX-100 decks with the gear idler modification are rare and far between. That makes your deck particularly worthwhile.

I'd always been an admirer of their decks but never actually owned one (instead I had others such as Pioneer CT91a, Denon DRM-44HX, Aiwa's) but I've always wondered just how good Nakamichi's were. And now, thanks to the wonders of eBay, I own 15 of them! I am looking to get them back up to spec again, they all need a few things doing to them and I will be after various parts for them on and off for a while. I will happily pay for anything offered through Paypal. I am still a fan of cassettes, purely because, sonically, it's still the best replay format on the market. My first request is for a few cassette bay back panels (for the BX series), 5 or so would be nice, including the small black mounting screws. I hope I've explained the part correctly, it's basically the cosmetic metal part that, once removed, allows access to idler wheel workings. Decks are BX150's, BX300's. Thank you.

That transistor is slightly undersized and tends to open up a lot. Willy" Thanks, Willy! I'll be sure to watch that transistor. Turns out it was simple. Looking through the schematic to see what they both had in common, I started on the +12 rail, and assuming it was a cap, started rechecking the 470u, which checked ok from the component side, but I found did not from the trace side. I swapped it out and she fired right up. The solder pad on one side, once I sucked off the solder to replace it was missing. I had to bridge it from the previous & next component with a bit of lead from the cap. NEW PROBLEMS, of course. The left capstan stops rotating before the right one, by a few seconds,(they are within a fraction of a second of each other on my good Dragon) so I figure it needs a clean and lube. It has great W&F playing left (.03 and steady), but not as good playing right, normal direction (.05-.055, not as steady) all wow component. So I'll lube it up good and see what happens. Had to clean a bunch of old grease from the supply brake and hub (thanks for the hint, Tom).looks like it dripped down from the brake mech right above. Afte letting it play for a while, it sure seemed like the darlingtons on he motor control board got a bit hotter than they do on my good one. Did the old ones run hotter in general? A previous tech had replaced the belts and idler. The idler is not exactly square with the reel motor bras hub, but canted small amount. Problem? When you play to the left, (with no tape) and the left reel becomes the take up, it LOOKS and sounds like the counter fins are barely brushing the idler hub at the spring. (possibly a slightly undersized idler tire) Put a tiny amount of pressure on the idler to relieve some pressure from it off the reel hub, and the noise stops immediately. Release the pressure, noise comes back. The NAAC on this deck is much noisier than on my good one, so I unclipped the bowden and found it is much stiffer to slide than on my good one. In fact, on my good one there is a strong spring return. Not so with this one. There is a wimpy little spring at the slider mech near the head, but does almost nothing. Is my bowden cable bad, or were the early ones just not as smooth. I lubed the slide and any moving parts, and it moves fairly easy now, but nothing like my newer one. This one is early, SN 1417, vs my late one SN 249xx. Were thee different bowdens, and this is just normal? Still looking for a rewind button..parts deck anyone??? Gotta love working on these beasts. -------------- next part -------------- An HTML attachment was scrubbed...

On one tape, my Dragon started to make the 'clicking' noise from the azimuth adjustment (and a faint smell of overheated electronics). The tape that was a copy of a spoken word LP with faint music in the background. I figured it was because it couldn't lock onto a decent frequency signal. Then the next day I was playing a music tape and it just wouldn't play all the way thorugh, it kept stopping. After a couple rewinds->play, the tape just locked up, it was very difficult to turn the spools with my finger and the innermost edge (nearest the deck well) had been eaten. In the shell window I could also see that the tape was being miswound as the edges of a small portion of the tape were folded over the other wound tape. After clearing this, it played fine in my CR-7A, but still locked up in the Dragon. I continued to play other tapes in the Dragon, with 1 or 2 giving me problems with either stopping or the NAAC going wacky and clicking (with the audio cutting in and out). Then I realized I hadn't cleaned the heads/transport in many months. After a thorough path/head cleaning, no problems with the original tape (I didn't even hear any problems with ther portion of the tape the Dragon had eaten) or any others so far. I think that the NAAC may have had it's own problem though. When the door is ejected, the Dragon typically makes a sound (which I assumed was the NAAC resetting) for a couple seconds or so. However, when all the above was going on, when the door was opened it continued to make the noise indefinitely. Then one day, I just opened the door and let it go, and the noise eventually stopped and it was after this I no longer noticed the overheated electronics smell. I haven't noticed any descrease in sound quality, so I hope there was no permanent damage done to the NAAC.

Open your dragon top cover and look for the azimuth motor behind the transport for checking the state of NAAC drive. NAAC adjustment never stays on the original setting due to drift in caps on the comparator circuits/play circuits.  more than 50 % of the time I had to change the resistor value to get the 5 Khz phase adjustment in the Dragons I serviced - even the original circuit values do not help for adjustment. Also the playback amp signal level changes due to drift in componenet values. I also noticed poor tape transport in reverse including DD motor drive issues causing mistracking of NAAC. Most of the Dragons with serial number below 4000 have weired factory added components on the board - far from the Dragon service manual schematics indicate. I also see many orange caps in these serial number Dragons going bad.   Dragon needs regular service ( if you notice NAAC tracking problem) to set right these issues. Since Dragon troubleshooting is not for every one or someone without proper alignment gages/tapes as well as service experience, better send it to somebody having the tools and skills.   kannan --- On Tue, 12/22/09, Chris Rinewalt wrote: From: Chris Rinewalt Subject: Re: [naktalk] dragon ate tape in reverse play To: "Talk about Nakamichi Cassette Decks" Date: Tuesday, December 22, 2009, 12:01 PM A couple months ago, I had a similar problem. On one tape, my Dragon started to make the 'clicking' noise from the azimuth adjustment (and a faint smell of overheated electronics).    I think that the NAAC may have had it's own problem though. When the door is ejected, the Dragon typically makes a sound (which I assumed was the NAAC resetting) for a couple seconds or so. However, when all the above was going on, when the door was opened it continued to make the noise indefinitely. Then one day, I just opened the door and let it go, and the noise eventually stopped and it was after this I no longer noticed the overheated electronics smell. I haven't noticed any descrease in sound quality, so I hope there was no permanent damage done to the NAAC.           -------------- next part -------------- An HTML attachment was scrubbed...

However, one particular SONY SR-100 has one of my Dragons ( 1 out of three) go crazy in the reverse mode. This particular Dragon also had an issue on the reverse with a SONY Metal Master 90 on the reverse mode. this only happens on the beginning 3-5 minutes of the reverse side play. After that all is well. The single  side playing decks( close to 12 in all so far that I have- all Naks) have had no issue with any tape, including these two made infamous by my particular Dragon. This happens even after cleaning and demagging. So I presume its a Dragon transport issue after all in your case too as it was in mine.NOT A TAPE ISSUE.

The send me some new pinch rollers for the classic transport like in the ZX- Decks, This new pinch rollers did have very small, fine hair-cracks on the rubber. I did ask the japanese from what year the pinch rollers are, thinking the cracks come from the age of the rubber. The support office told be in Japanese; (I am married to a a Japanese girl ) "The pinch rollers are made in 2005, and the fine hair-cracks are in the rubber for making better contact to the tape. Then the friction is bigger, like on a car tyre." Be for that information I was thinking the rubber from the old pinch rollers are looking up-used and old. I attached a photo from this 2005 rollers to this mail, If the old pinch rollers from you Deck look still like this, there is no need to replace them.

It still makes the short motor sound (is this actually the sound of the ladder wire moving?) when powered on and when ejecting the tape - which I presume is rerturning the azimuth to it's standard position. Additionally, when I play a tape, I can hear this motor/wire movement for a somewhat longer time while the NAAC adjusts to the playing tape and the play light flashes, as is normal. I have not noticed any decrease in audio quality since the incident, but I haven't used it in about a month or so. If it was completely shot, I imagine the azimuth would have been totally skewed to a maximum angle (as evidenced by that clicking noise) and sound would have been horribly muffled, which it is not. And of course, there's still the sound of the motor/ladder wire moving normally when it should. I doubt the incident had any benefit to the deck, but as long as it did not ruin it, I'll chalk it up to the vagaries of a 24 year old machine. I did have Willy check this deck out last August after I received it, but I'm not sure if he examined the NAAC, as it was just a cursory examination to determine if the deck was in "normal" condition. In any event, I think it's still performing well and I'll just have to keep my fingers crossed.

Last year I listened through the RX-505, this year through the 700ZXL(so far)-both restored by our Willy H. here. I'm not really a religious person, but young boys singing in a choir before their voices breaks...well, there just isn't anything else like it in the world. Even as disciplined as the Mormon Tabernacle Choir is, they can't touch the Vienna Boy's Choir. I don't really feel like a A/B/X comparison between the two decks, but I think the 700ZXL might have a possible lead in this type of music. Today I used the 700ZXL all day and tomorrow I'll use the RX-505. Thanks Willy!! Happy Holidays All!

Hopefully it won't be a frequent issue. I can imagine the un-cool feeling one would get when their zx9 decides to turn a tape into Christmas dinner. ______________________ I've had the occasional - very occasional - tape get chewed up in one or other of my machines In all cases it proved to be a problem with the cassettes sticking. I found this when I finally got the tape out and turned the spools with my little finger. But on one infamous occasion I had a small batch of C100 TDK SA that would do it in the ZX9 and not in my Pioneer CTS 830S. (It does say in the manual, however, not to use tape that long in the ZX9 but when I mentioned it at the time, plenty of voices came out to say they'd all used tapes longer than C90 that gave no problem in their ZX9's and/or other Naks.) ------------------------------ Message: 2 Date: Wed, 23 Dec 2009 08:39:26 -0800 From: Willy Hermann Subject: Re: [naktalk] Parts request for Nakamichi BX range To: Talk about Nakamichi Cassette Decks Message-ID: <4b6f92900912230839ma1533e9j86df74f3cb430586 at mail.gmail.com> Content-Type: text/plain; charset="iso-8859-1" Stephen - A few months ago I bought a lot of parts from a servicer who was calling it quits and in that lot were (TA DA) five back plates for the BX single capstan series.

Open your dragon top cover and look for the azimuth motor behind the transport for checking the state of NAAC drive.

On one tape, my Dragon started to make the 'clicking' noise from the azimuth adjustment (and a faint smell of overheated electronics). I think that the NAAC may have had it's own problem though. When the door is ejected, the Dragon typically makes a sound (which I assumed was the NAAC resetting) for a couple seconds or so. However, when all the above was going on, when the door was opened it continued to make the noise indefinitely. Then one day, I just opened the door and let it go, and the noise eventually stopped and it was after this I no longer noticed the overheated electronics smell. I haven't noticed any descrease in sound quality, so I hope there was no permanent damage done to the NAAC. -------------- next part -------------- An HTML attachment was scrubbed...

Last year I listened through the RX-505, this year through the 700ZXL(so far)-both restored by our Willy H. here.  I'm not really a religious person, but young boys singing in a choir before their voices breaks...well, there just isn't anything else like it in the world. Even as disciplined as the Mormon Tabernacle Choir is, they can't touch the Vienna Boy's Choir. I don't really feel like a A/B/X comparison between the two decks, but I think the 700ZXL might have a possible lead in this type of music. Today I used the 700ZXL all day and tomorrow I'll use the RX-505. Thanks Willy!! Happy Holidays All!

Hopefully it won't be a frequent issue. I can imagine the un-cool feeling one would get when their zx9 decides to turn a tape into Christmas dinner. ______________________ I've had the occasional - very occasional - tape get chewed up in one or other of my machines  In all cases it proved to be a problem with the cassettes sticking.  I found this when I finally got the tape out and turned the spools with my little finger.  But on one infamous occasion I had a small batch of C100 TDK SA that would do it in the ZX9 and not in my Pioneer CTS 830S.  (It does say in the manual, however, not to use tape that long in the ZX9 but when I mentioned it at the time, plenty of voices came out to say they'd all used tapes longer than C90 that gave no problem in their ZX9's and/or other Naks.) ------------------------------ Message: 2 Date: Wed, 23 Dec 2009 08:39:26 -0800 From: Willy Hermann Subject: Re: [naktalk] Parts request for Nakamichi BX range To: Talk about Nakamichi Cassette Decks Message-ID:     <4b6f92900912230839ma1533e9j86df74f3cb430586 at mail.gmail.com> Content-Type: text/plain; charset="iso-8859-1" Stephen - A few months ago I bought a lot of parts from a servicer who was calling it quits and in that lot were (TA DA) five back plates for the BX single capstan series.  I only have four screws though.  Contact me off the forum and we'll arrange it.

Open your dragon top cover and look for the azimuth motor behind the transport for checking the state of NAAC drive. NAAC adjustment never stays on the original setting due to drift in caps on the comparator circuits/play circuits.  more than 50 % of the time I had to change the resistor value to get the 5 Khz phase adjustment in the Dragons I serviced - even the original circuit values do not help for adjustment. Also the playback amp signal level changes due to drift in componenet values. I also noticed poor tape transport in reverse including DD motor drive issues causing mistracking of NAAC. Most of the Dragons with serial number below 4000 have weired factory added components on the board - far from the Dragon service manual schematics indicate. I also see many orange caps in these serial number Dragons going bad.   Dragon needs regular service ( if you notice NAAC tracking problem) to set right these issues. Since Dragon troubleshooting is not for every one or someone without proper alignment gages/tapes as well as service experience, better send it to somebody having the tools and skills.   kannan --- On Tue, 12/22/09, Chris Rinewalt wrote: From: Chris Rinewalt Subject: Re: [naktalk] dragon ate tape in reverse play To: "Talk about Nakamichi Cassette Decks" Date: Tuesday, December 22, 2009, 12:01 PM A couple months ago, I had a similar problem. On one tape, my Dragon started to make the 'clicking' noise from the azimuth adjustment (and a faint smell of overheated electronics).    I think that the NAAC may have had it's own problem though. When the door is ejected, the Dragon typically makes a sound (which I assumed was the NAAC resetting) for a couple seconds or so. However, when all the above was going on, when the door was opened it continued to make the noise indefinitely. Then one day, I just opened the door and let it go, and the noise eventually stopped and it was after this I no longer noticed the overheated electronics smell. I haven't noticed any descrease in sound quality, so I hope there was no permanent damage done to the NAAC.                 -------------- next part -------------- An HTML attachment was scrubbed...

In any case, I could be days hunting for various small screws and never find the right ones. So, no, I cannot provide screws (BTW, they are all standard metric sizes). As to the panel itself, the MR-1 panel should physically fit just fine, but, IIRC, two of the knob legends will be incorrect for the BX-300. I don't have the panel in front of me, but, from dim memory, 'Pitch' on the MR-1 is marked as 'Bias' on the BX-300 and 'Pitch' on the BX-300 is something else ('Level'???) on the MR-1. And, of course, there's a different model number on each.

After going through the recommended mechanical adjustment procedures, I determined that the capstan motor is defective. It seems that the adjustment potentiometer, which is part of the motor, is broken. The motor spins too fast and the adjustment screw appears to be broken inside the motor housing.

I suspect the repairing the motor is would be rather tedeous. Failing that, I would consider replacing it with a stepper motor.

When using the tape2 source there is an certain amount of distortion. It sounds as if the input signal is far too loud. Maybe a not so good working transisitor? The other problem has to do with switching the input with the remote control. Switching manual to tape 3 there is no problem but switching with the remote the knob turns counter clockwise and clockwise several times and it cannot make a choice. The service manual is hard to find i think?

Firstly I have a Dragon that I bought from Ebay that seems to work perfectly, the only thing is that I can smell it. It heats up and gives off that certain electrical smell that says something is not happy. Not that anything stops working or really gets hot. I took the cover off yesterday and nothing looks burnt but the main board(upside down on the right) was where the heat came from. Should i worry? This leads me the second question. Australian electricity is 240v 50hz and my voltage was up to 255v yesterday, my Australian issue dragon has a nominal voltage of 220v is that a worry? Are my two worries related?

When I opened up the machine a tubular piece of plastic with grooves in which attaches to the mode motor and drives the cam wheel fell out so I assume this was the problem, for some reason it had fallen off of the mode motor shaft. I undid the motor as your instructions and re attached the piece of plastic to the shaft and just to be sure sprayed Deoxit into the motor. I reconnected everything and it now works perfectly. I hope that piece of plastic does not fall off again! Strangely though, your picture showing which screw to remove to release the mode motor shows 2 other screws above which secure a plate which appears to stop that piece of plastic from coming away from the shaft, my machine does not have that plate or any sign of one ever being fitted! Is it a modification? Also your piece of plastic has a round end to it, mine just has a hole at each end. Is it a common problem this piece of plastic falling off of the mode motor shaft? Thanks again for all your help. David. -------------- next part -------------- An HTML attachment was scrubbed...

This means that, while recoding on the 528, one can hear the recording as it is made (actually, a split second later. This allows the user to make fine level and/or bias adjustments for best recorded sound. Tape monitoring requires additional circuitry. This tends to drive the price up. Because of that, the 581 was the cheaper of the two. It does, however, include two expensive features (test tone generator and three discrete heads) that normally come only on decks capable of tape monitoring. Thus, the price difference isn't as much. People that care about their recordings sound quality tend to insist on tape monitoring capability. Owing to the comparatively small price difference between the 581 and 582, the latter is their preferred deck. -- Ron -------------- next part -------------- An HTML attachment was scrubbed...

Sometimes, it works well...when it does not, it is impossible to play, FF or REWIND. The transport seems stuck!! suddendly, the motor simply stops and no motion is anymore possible. Disconnecting the connector of the mechanism to the main PCB, and reconnecting it, most of the times solves (for sometimes) the problem! I am almost sure that it is due to electronics and coming from "outside" the mechanism, as when I exchange the mechanism with the second one working perfectly, the problem is still there. What is the "shutt-off sensor buffer" listed on the "mechanism control section"? Would you have an idea of where or what I could look for? Can it come from IC602?

The 670ZX is a keeper for sure.... there are those who maintain that the 670ZX is a better playback machine than the 680ZX. The trouble with selecting out of the other decks, the CD1 has the useful play azimuth adjust, and the BX300 has pitch control.. both useful for replay of tapes of mixed origin..why Nak never made a deck with both..?? I also have a 481 and despite 'appearances'.. mine is also a beguiling sounding deck for replay, and for me a keeper. IMHO the 48X's have a unique sound within the ranks of Nakamichi.. a warm, full sound with a slightly 'blowsy' bass.. personally I like these decks. The 580's are 'classic' sounding and also great decks.. potentially more useful than the 481 thanks to adjustable bias and level ala 600's, but as your incoming 580 is likely to be a US fixed 110V deck, rather than a 110/220-240V switchable..not so appetising?. As for speakers.. get something around 91/92db+ sensitivity... I just acquired a little shanling MC30 for the study.. 3 humongous Watts of valve power, but with the right speakers goes plenty loud enough. cheers, Martin > Everyone says keep 670 > 2 votes for the CD1 > 2 votes for the 300 > 1 vote for the 580 > No votes for the 481 > > Thats helpful and thanks for your input, especially Ron.

An E suffix (stands for 'Europe') denotes 240VAC (for Australia and UK), with a 220VAC tap (for Europe). The taps is internal and can be changed by anyone that owns a soldering iron. Finally, there is an O version (stands for Other) that has a dual primary and can be set for either 115VAC or 230VAC by a slide switch that is accessible on the rear panel. -- Ron Antoine Deschênes wrote: > In US, there's rarely a voltage switch, and the 240V windings are > often not even present. > > 2009/1/31 : > >> Everyone says keep 670 >> 2 votes for the CD1 >> 2 votes for the 300 >> 1 vote for the 580 >> No votes for the 481 >> >> Thats helpful and thanks for your input, especially Ron.

All of the transformers except the one for US use are shown in the schematic as having both a 240V winding and a 220V winding - you will certainly have one of the three shown as such. It certainly seems that you could have the transformer tap changed from 220V to 240V - this would be a trivial job for a competent electronics technician, and I would recommend that you have this done. While Australia does have nominal 240V, there are places where as much as 10% over-voltage is occassionally in evidence. Your reading of 255V is not by any means unusual. By operating your Dragon at 240V and above at times, you will considerably increase dissipation, and your hot smell is probably at least in part caused by this. The transformer itself will be running quite hot - and if this part fails, the repair cost won't be attractive. I would also pay attention to Tom's advice, and maybe it would be a good idea to put your temperature calibrated finger on all the semiconductor heatsink tabs to see if any stand out as much hotter than the rest. You may have some devices that need replacement, and it's better to act before a device fails entirely. I don't wish to be alarmist, but if a device has a 240V tap, it makes no sense not to use it in this country. Regards John Gipps Hi all, I have a couple of questions to ask. Firstly I have a Dragon that I bought from Ebay that seems to work perfectly, the only thing is that I can smell it. It heats up and gives off that certain electrical smell that says something is not happy. Not that anything stops working or really gets hot. I took the cover off yesterday and nothing looks burnt but the main board(upside down on the right) was where the heat came from. Should i worry? This leads me the second question. Australian electricity is 240v 50hz and my voltage was up to 255v yesterday, my Australian issue dragon has a nominal voltage of 220v is that a worry? Are my two worries related?

Something that I have never tried though, is the maximum number of memory slots for the RAMM system. Most literature spots it at 30 for both the 1000ZXL and 700ZXL. However, one old timer mentioned to me that it is 15 for the 700ZXL. He may have mistaken it for the number of indicators, I do not know. Regards, Bala Kevin Fetner wrote: OK, if I wasn't confused before, after reading six pages in the owner's manual about RAMM operation, I certainly am now. Is it possible to: code a RAMM signal at the beginning of a tape (and at the end of the tape), to get the deck into continuous Play mode for a whole tape side?

Maybe it wasn't used enough and took a little while to get back to speed. The bloke I bought it off said as much, it was the reason he sold it.

However, the allure of Aiwa, Akai and Teac still remains as they exude a different sound and feel to the music - thus the attraction to them would still remain to most of us Nakkers I am afraid. Happy Nakking and non-Nakking!

That *some* (actually, very, very few) components on the market do not have a power switch is irrelevant. In any case, this only applies to equipment that draws little to no power in the idle state and *absolutely* not to rape decks that have a motor running constantly when powered on. In general, keeping equipment constantly on is not a good idea (with some exceptions.). Anyway, what I was specifically commenting on was the notion that 'electrons will flow more freely' when equipment is kept constantly on. I know that audiophiles cling to some bizarre rituals, but this one is simply incorrect. Regards, -- Ron jayson levitz wrote: > Hi Ron. > > I beg to differ with you on this issue.

You may hit them -- or you may not; so, good luck! How about doing some good, old signal tracing work? Put the deck in record mode and 'listen' to the supply rails and grounds in the associated circuitry, going on to the bias oscillator area -- these are the most likely suspects. Then, apply a signal to the input and trace it from the input jacks all the way to the record head. That will show up the exact point where the crackle is injected into the signal path. If you do not have a signal tracer, do you happen to have a small audio amp and speaker that can be put to use as one? If that is out of the question as well, consider that the relay may still be bad (in spite of the cleaning). Temporarily jumper the record contacts and see if that clears up the problem. Another possibility is a hairline crack in a soldered joint or PCB track. A freezing spray can is very useful in locating these, (even though it can be difficult to do without some sort of signal tracing capability).

Nak designed such deck to run the capstan motor whenever powered, because it takes the capstan motor several minutes to achieve best speed stability. However, the capstan bearings dry up during use. As a result, the deck requires routine maintenance and bearing lubrication far more often if left powered up for hours on end. In my case, my deck required lubrication every few months until I read a similar discussion (probably here, on NakTalk). I started to turn it off whenever not in use and can't recall even the last time I lubricated it. I suspect that before, it used to spend more idle 'on' time than actual playing. -- Ron > Otherwise it might be akin to raping the deck( pun intended) and not > taping the deck! ;-) > > Regards, > Ram > > > --- On *Tue, 2/3/09, Ron //* wrote: > > From: Ron > Subject: Re: FW: [naktalk] excess voltage > To: jmlevitz at yahoo.com, "Talk about Nakamichi Cassette Decks" > > Date: Tuesday, February 3, 2009, 9:44 AM > > > Well, Jayson, this is not a question of opinion, but of > engineering knowledge.

The thing that confused me was looking at Graham's pictures on "tapeheads" of how to dismantle and repair the mode motor. The pictures show 2 extra screws (above the screw used to remove the mode motor assembly from the machine) that secure a plate which is "L" shaped and aligns with the tip of the mode motor shaft which presumably stops the worm gear from coming away from the shaft! Also the tip of the worm gear has a round plastic cover over the tip of the motor shaft. My machine has neither the plate (or any sign of the 2 screw holes which hold it in place) or of the plastic cover at the tip of the worm gear!

I personally, have heard no difference between a warmed up deck or a cold one. Speakers may need some warming up though as per literature on them, but not tape recorders. In fact, I was advised by Jeff Galin of ESL to not leave my restored 680ZX on, unless I was using it and follow this mantra with all my decks. This is especially true for decks equipped with DD Sankyo transports. Nak designed such deck to run the capstan motor whenever powered, because it takes the capstan motor several minutes to achieve best speed stability. However, the capstan bearings dry up during use. As a result, the deck requires routine maintenance and bearing lubrication far more often if left powered up for hours on end. In my case, my deck required lubrication every few months until I read a similar discussion (probably here, on NakTalk). I started to turn it off whenever not in use and can't recall even the last time I lubricated it. I suspect that before, it used to spend more idle 'on' time than actual playing. -- Ron Otherwise it might be akin to raping the deck( pun intended) and not taping the deck! ;-) Regards, Ram --- On Tue, 2/3/09, Ron wrote: From: Ron Subject: Re: FW: [naktalk] excess voltage To: jmlevitz at yahoo.com, "Talk about Nakamichi Cassette Decks" Date: Tuesday, February 3, 2009, 9:44 AM Well, Jayson, this is not a question of opinion, but of engineering knowledge. That some (actually, very, very few) components on the market do not have a power switch is irrelevant. In any case, this only applies to equipment that draws little to no power in the idle state and absolutely not to rape decks that have a motor running constantly when powered on. In general, keeping equipment constantly on is not a good idea (with some exceptions.). Anyway, what I was specifically commenting on was the notion that 'electrons will flow more freely' when equipment is kept constantly on. I know that audiophiles cling to some bizarre rituals, but this one is simply incorrect. Regards, -- Ron jayson levitz wrote: Hi Ron. I beg to differ with you on this issue. Some high-end audiophile equipment, like amps and preamps, are supposed to stay on constantly. In fact, many lack an on/off switch on their front panel. Case in point - I have a Jeff Rowland Design Group Model 5 amp and their Coherence One preamp, and this equipment stays on all the time. The amp stays on in a stand-by mode, but the preamp stays on at full power constantly. I also have a Magnum Dynalab tuner that stays on all the time, and the power switch just activates the displays. Equipment like this actually lasts longer in a constant powered-up state. However, Nak cassette decks do not fall into this category and should NOT be kept powered-up constantly.

I bought my Dragon from a guy who owned ten Nak decks. When I first got my Dragon, it smelled like cigarette smoke as I ran it. The previous owner mention that he never smoked around his equipment. I sometimes record some 20 LP's in a weekend, leaving the Dragon and all recording equipment on all weeking. I simply feel the electrons will flow more freely. I wonder why people that have no idea still feel compelled to express it. No, the electrons do not 'flow more freely' if equipment is left on. That's because electron flow in any circuit is wholly determined by voltage and impedance and the temperature change, expressed in degrees Kelvin, is too small to affect either. But, there is often a grain of truth in urban legends. Some equipment should be left on because, first, the small temperature rise prevents humidity build up and, second, when it is important that equipment parameters are as stable as possible (such as, in test instruments). Neither consideration applies to audio equipment in the home. Just thought inquiring minds may want to know :-), -- Ron Never had a problem with my Dragon.

Possibly? Bob N > That depends on the torque exerted by the motor vs. the force required to remove the worm gear. Well, it's a tiny motor and removing the worm gear does take some effort. It is possible? Sure. Is it likely? I think not. While playing with these decks we occasionally do encounter inexplicable mysteries... Here's a story: I Recently received a parts BX-100 (for the shipping) that turned out to look real nice -- too nice to be cannibalized for parts. Turned out the PB/REC relay was shorted internally, so I took it apart and -- lo and behold -- the common leaf of a contact had 'jumped' over the NO contact, so that all three leaves were permanently shorted. Logically, this could never happen, as the force required to somehow move the common contact over would be tremendous. Yet, at one time, the relay must have worked fine. What happened? Could someone remove the relay, put in serious effort to cause the fault, then cleanly buttoned it up? Not likely. Is there any reasonable explanation to this mystery? Space above the relay is seriously limited and the only relay I had on hand (or could order) that would fit, was a MIL spec., hermetically sealed, gas filled, metal enclosed relay listing for about $150, which is 3 to 4 times what the deck is worth *after* the repair. Yet, I must have got this relay for a lot less and have had it on the shelf for ages, so I kludged it in. I then repaired some other things and now have a nicely working deck with a PB/REC relay that will last much longer than the deck itself or, for that matter, me :-). -- Ron > > --- On *Tue, 2/3/09, Ron //* wrote: > > From: Ron > Subject: Re: [naktalk] Nakamichi BX-300 Problem > To: "Talk about Nakamichi Cassette Decks" > Date: Tuesday, February 3, 2009, 12:09 PM > > > Not to be contrary, but IIRC, the worm gear is held in > place by friction and does not require a clip to stay put. > As a matter of fact, I am a bit confused about what > happened to your deck.

See the first mechanical adjustment in the service manual. Normally, I would suspect this adjustment, except that the deck worked fine in reverse. Still, it's easy to check it (VR601) so I would do this first. I would then carefully check both the idler and hub mating surfaces. If glazed, I would thoroughly clean again.

One could have never have guessed in the late 70s that something like this could even happen to Nakamichi. Could it be mis-managment that led to the demise and subsequent mis-adventure of the Nakamichi name, like how the current economic crisis was bown out of credit mis-management more then a natural economic cycle ? Nakamichi's nice showroom and office in the business district of Singapore has been closed more then a year ago and has remained vacant ever since. They have since moved to an office in an industrial district. Regards, Bala Wouter Heijke wrote: It's funny.

It will cut through organic pollution with no problem. Be aware, though, that MEK is nasty stuff. Use *only* in very well ventilated areas and avoid breathing 6the fumes at all cost, as it can do damage to your lungs. Also, avoid letting it touch your skin. Also, MEK will damage finishes on contact, so the front panel and case must be protected.

My guess is that the Sankyo design started without that plate and that the worm gear was help in place by high friction, but due to service difficulties, Sankyo reduced the friction and added the plate (which they call 'thrust spring') and the thrust bushing to preclude the problem encountered by the OP.

I do not need so many and its largely due to my Nak evangelising that I e[Graham Nelson] .. The 580 needs changing to UK voltage from US 110v or using with a large iron lump attached to it. I dont know the sonic character of the 580 series . or the condition of this one but it comes from a hifi buff, unused for some time I gather. Seemingly Nak UK do not service these anymore - or at least not fully. The 481z is built like a tank and holds much affection as my first Nak but is probably a good one to sell confidently , serviced and set up for some years. Mostly the recipients do not have what buffs would call hifi but as I say are musicians who want to get at their old stuff - a desire I fully support thus its mostly playback they need. So comments about wether the 110 v transformer can provide 240v take outs would also be helpful. Shown a photo I can do that sort of thing but can also get it done pro nearby if its tricky to get right.

Glazing was on the reel hub and since it runs well for the reverse didnot touch the idler wheel rubber. For the reel hub I used extra fine abrasive paper (it souds strange I know) touched it while the hub is turning by the motor few seconds and the glaze was disappeared then I cleaned the surface with a cotton swab with alcohol moistened. Looks fine. Yesterday I've loaded a cassette and engaged the deck to continuous playback for 12 hours. In the morning it was still running smoothly without any noise. Now seems no problem thank you for your advice. Regards.

However, my ZX7 is really noisy when in PLAY, FF orREWIND mode. I tried to clean the surfaces of the idler tire and the hubs with isopropanol but it did not improve much! I think I will have to dismantle the mechanism to access the idler tire. Any advice for that? or faultly manipulations not to be done? The other problem that it gets is that it does not want to move in play, but I think more and more that it is due to an old cam belt, because when I help the cam gear to rotate until the end of rotation, it swithes in PLAY mode. (If I do not help, it plays but I can ear the control motors that does not stop because the cam gear does not reach it very final position) bernard EUGENE GARNER a écrit : > bernard, Methyl Ethhyl Ketone. > gene > > ------------------------------------------------------------------------ > *From:* boitrel > *To:* Talk about Nakamichi Cassette Decks > *Sent:* Friday, February 6, 2009 12:24:27 AM > *Subject:* Re: [naktalk] DRAGON forward playback need advice for a solution. > > Ron, > > I do apologize but don't know what MEK stands for?

I think this would have been in the early 80s. About a year ago, because my original tape was so old, and had so many sections where a little damage had occurred, I began to wonder if it was still giving me accurate results - so I located one for sale on eBay, paid 115 Euros for it, and on arrival it appeared to be brand new and unused. Comparing it and my old track tape, they give precisely the same adjustment. So that's the first bit of good news - an old track tape with enough undamaged tape on it can still be used - so you may be able to buy a used one on eBay for (hopefully) not too much. Secondly, I know there are people in this group who have either produced a track tape, or are working on it. Tom will know the answer to this. Thirdly, you can do a reasonably close track alignment, if you have a tape recorded on a correctly adjusted deck. Make a tape on the correctly adjusted deck with Left and Right channels recorded at 400Hz and recording level 0dB (200nW/m on a Nakamichi). Play this tape on your 480/480Z, or whatever you're adjusting the track of, and maximize the output on both Left and Right channels by adjusting track (head height). Follow this by adjusting azimuth on this same 400Hz tape (if you have a CRO, look at the phase difference between L and R), and repeat the two adjustments (track then azimuth) until you have maximum playback level on both channels, and correct azimuth. (You won't get a very sensitive azimuth adjustment at 400Hz, but as long as azimuth is close, the track adjustment will work). This procedure will get you quite close, but obviously depends on the accuracy of the track on the deck that recorded the 400Hz tape.

So how do you adjust the head height on these or rather do you have an idea how to get hold of the tape? I don't need an azymuth tape. Just the track alignment or head height and I don't want to adjust anything else on the decks as the original electronic adjustments seem to be still good.

The mounting facilities for a record head are simply not used on a 480/480Z.RegardsJohn Gipps -------------- next part -------------- An HTML attachment was scrubbed...

I have never found it necessary to use anything more powerful than ethanol as a solvent to clean parts during Nakamichi service. Ethanol is far more effective than isopropyl alcohol when it comes to cleaning Nakamichi parts (including rollers). I? wouldn't use MEK myself in the servicing of a deck. MEK is a powerful solvent, but should be used with caution. If you do decide to use MEK, it's important to use it in a well ventilated area - the fumes from MEK can give you a headache, and at high levels, can cause brain damage - if you've heard of "glue sniffing" - MEK is one of the solvents sniffed and it's present in some contact cements. (This habit has caused brain damage, and in rare cases has caused death.) MEK is used a lot in speaker repair. Quite a lot of MEK is required to dissolve adhesives to remove cone and coil assemblies in speaker reconing for certain brands (most of my reconing was for JBL and B&W) - depends on the adhesive used. So I've used heaps of the horrible stuff in speaker reconing, but would not use it unless it was required for a particular task. Maybe my extensive use of MEK over a few decades on speaker reconings explains why I'm so slow to service Nak decks these days :-) ?

Therefore because it is so concentrated a few precautions are in order, like open window ventilation, use of gloves, and Q tips in a small capful to keep it in manageable quantities while being handled. I don't think this method poses too great a health risk (like say ricin or plutonium), but in a house where children inhabit I would find a safer solution. -------------- Original message from BOEING747600 at aol.com: -------------- HI John, After reading your post I would suggest to all here NEVER EVEN GO NEAR MEK!!

Quite a lot of MEK is required to dissolve adhesives to remove cone and coil assemblies in speaker reconing for certain brands (most of my reconing was for JBL and B&W) - depends on the adhesive used. So I've used heaps of the horrible stuff in speaker reconing, but would not use it unless it was required for a particular task.

Message-ID: <9001F89E8B697947ACDFD967BE50657D171511@STT1EVS62.TTHMC.LOCAL> Hello, I have 2 DRAGONs both are suffering fromm NAAC. The one which running for now has the following symptoms; * Alignment indictor and the pointer is coincides both for the forward and reverse directions when the cassette door is opened and pressed forward and reverse playback buttons. * I have an AKAI 10Khz -15db Azimuth Test Tape. When it is loaded alignment indictor and the pointer is also coincides to both directions after few seconds of back and forth movements. * When I put the deck into calibration the marks are not coincides this makes me to think that the record head is not matching the offset position of the playback head. (When I saw this I ve checked also the CR7 during calibration and found that it also slightly moves the PB Head) so I didnot touch the REC head since this is not the problem. * When I playback the pre recorded tapes time to time during playback (one side or both side of the tape) NAAC generates strange mechanic sound and when I checked it reached to end of its stroke. What is the problem of this "Legendary :)" NAAC ? Is there anything to replace? I didnot see any trouble shooting with this system inside the manuals so I need any kind of advice. The second one; Easy to explain the problem :) I heard a running motor sound when the cassette door is left open it stops when it is closed. So I checked inside it is the NAAC motor. I ve disassabled the steel wire and saw that the lever stuck at the end of stroke position and not moving. Can it be repaired or I have a new parts deck? Thank you for reading my NAAC story. Now I can say that I decided to show special attention to my CR7 and never compare it with the Legendary DRAGON because CR7 is Truth. :))) -------------- next part -------------- An HTML attachment was scrubbed...

Referring to Fig 2.9 on page 10, when you have removed the 5 screws (F01), and the screw F02 (make sure when you reassemble that F02 goes into the correct location), and released the 3 springs that hook onto the white nylon tabs on the sub mechanism chassis assembly (see page 54 Fig 8.8 item 09), then you will be able to lift the sub mech chassis away. The cam pot (vol control) with the coupler part F10 in Fig 2.9 will easily disengage from the cam - you don't need to disassemble that section as described in section 2.21. When you reassemble, the pot coupler fork must straddle the part of the cam that you removed it from - disassemble slowly so you can see how the coupler engages. This is all you have to worry about in relation to the cam pot. When you reassemble, and reattach the 3 springs, put a little dob of adhesive on each spring end just as you will have removed this hardened dob of glue on disassembly. A suitable glue is a contact cement or similar.

On the subject of solvents, cleaning and health etc.. Rule number one: always start with the most mild solvent cleaner!! it is better to work your way up in strength or solvency than try to go to weaker solvents.. often the damage is already done. Ethanol vs Isopropyl alcohol (IPA)..I use IPA, but there is not a lot in it for our purposes.. use what you can get. Both will absorb atmospheric water is left unsealed. However, your chances of getting good IPA is a lot better than getting good ethanol. Commercially available Ethanol, because it the 'happy' component of any beer, wine or spirits we drink is usually denatured in some way.. usually the addition of 3-5% methanol, and is sold as methylated spirits.. which imparts it's own health problems ( in many ways it is worse than MEK).. so I only use it for cleaning if I haven't got any IPA handy. If you are really stuck, use a good vodka!!.. and probably Sake would work equally as well. Also, unless you are sourcing 99%, or analar grade ethanol/ IPA, it will contain about 5% water... don't worry about it.. the alcohol will take the water with it as it evaporates so no moisture should be left on your rollers or heads. Just a word on rubbing alcohol..I don't use it... depending upon supplier, this can be quite variable in composition. Always it is an alcohol /water blend and there is often a difference between medical and sports grades...... "proper' medical rubbing alcohol better known as 'sugical spirit' can be between 70 -99% ethanol by volume, with water and methanol making up the balance. So-called sports grade stuff is usually 70% IPA and water, but as always.. read the label. MEK is an effective solvent for many things, and has good cutting power. It can be a good solvent for non vulcanised rubbers and plastics, and is very useful for deglazing very shiny pinch rollers if you have no replacement parts, and in this case the mechanism is best left overnight for the MEK to evaporate. It is a good grease solvent too, and will be no more detrimental on the transport components than alcohol.. but remember rule number one above :o). Healthwise.. no solvent is ultimately good, discounting moderate amounts of red wine, whisky etc... and often the more 'foul' smelling ones cause less damage as you get out of the way sooner!. Solvent affects are often accumulative and depend upon the level of exposure. Acute exposure to MEK will cause irritation to the eyes, nose and throat short term .. and this is the level that most people realise that they need better respirators or ventilation. Further exposure can lead to depression, headache and nausea. Chronic/long term effects can result in neurological damage, liver and kidney function impairment, and respiratory damage.. but that is not just MEK.. ethanol/IPA/methanol can lead to the same and toss in eye damage as well. In extreme exposure cases, death can result.. but again, applies to all chemicals we know as 'solvents'. Lastly, there is as much mis-information on the net as good info. If you really want to know about a chemical..search the EPA site, or your local OSH site.. read a reputable source.. not just refer to the 'wiki'. best regards to all, Martin > The way I'm reading this, MEK is extremely effective as a solvent and > cleaner.

The biggest problem is trying to keep this stuff out of your body. It comes into your system thru your skin and thru your breathing. I don't recomend this, but if you put any these solvents on your skin it will dislove right into your body thru your skin. So diffently wear hand protection and eye protection to keep it out of your body. If you breath to much of the fumes in, it could make you dizzy and sick so always use a fan to blow the fumes outside. So far so good as far as my health goes!!!!!!

As a matter of fact, I posted as much several times and you'll see the same warning on the can itself (and more -- such as how flammable the stuff is). Still, it is not clear to me why would anyone avoid using MEK altogether, even though simple precautions can alleviate all risks. . I wouldn't use even a simple lathe without heeding reasonable safety rules (a guy I know lost three fingers in less than half a second when he didn't), yet I wouldn't avoid using the tool in my hobby whenever needed.

Hello, I have 2 DRAGONs both are suffering fromm NAAC. The one which running for now has the following symptoms; * Alignment indictor and the pointer is coincides both for the forward and reverse directions when the cassette door is opened and pressed forward and reverse playback buttons. * I have an AKAI 10Khz -15db Azimuth Test Tape. When it is loaded alignment indictor and the pointer is also coincides to both directions after few seconds of back and forth movements. * When I put the deck into calibration the marks are not coincides this makes me to think that the record head is not matching the offset position of the playback head. (When I saw this I ve checked also the CR7 during calibration and found that it also slightly moves the PB Head) so I didnot touch the REC head since this is not the problem. * When I playback the pre recorded tapes time to time during playback (one side or both side of the tape) NAAC generates strange mechanic sound and when I checked it reached to end of its stroke. What is the problem of this "Legendary :)" NAAC ? Is there anything to replace? I didnot see any trouble shooting with this system inside the manuals so I need any kind of advice. The second one; Easy to explain the problem :) I heard a running motor sound when the cassette door is left open it stops when it is closed. So I checked inside it is the NAAC motor. I ve disassabled the steel wire and saw that the lever stuck at the end of stroke position and not moving. Can it be repaired or I have a new parts deck? Thank you for reading my NAAC story. Now I can say that I decided to show special attention to my CR7 and never compare it with the Legendary DRAGON because CR7 is Truth. :))) -------------- next part -------------- An HTML attachment was scrubbed...

The Dragon doesn't use a belt in the capstan drive and a glazed idler tire will cause the machine to shut off, not to drag. The problem could be frozen or sluggish pinch roller rocker arms or it could be an electronic problem in the direct drive circuit. Without a tape loaded, press play and see if the pinch rollers come up and contact the capstan shafts. If they do, take the top cover off and look at the capstan flywheels. Are they turning? If so do they slow down or stop when play is pressed? If the problem is sluggish pinch roller rockers it's something you can fix. If it's the direct drive electronics I would suggest sending it to a pro.

You are quite right, I had to push quite hard to get the worm gear back onto the shaft.  I don't know how it came off, but there it was lying at the bottom of the machine. The thing that confused me was looking at Graham's pictures on "tapeheads" of how to dismantle and repair the mode motor.  The pictures show 2 extra screws (above the screw used to remove the mode motor assembly from the machine) that secure a plate which is "L" shaped and aligns with the tip of the mode motor shaft which presumably stops the worm gear from coming away from the shaft! Also the tip of the worm gear has a round plastic cover over the tip of the motor shaft. My machine has neither the plate (or any sign of the 2 screw holes which hold it in place) or of the plastic cover at the tip of the worm gear! Would I be right in presuming that the photographs show a modified BX-300?  Maybe somebody's worm gear also became detached at some time!

NR-0051 appears to deal with measuring the laser's power.  I don't have the equipment to measure that, so it's not urgent for me.

This improved things considerably, but I still noticed a bit of low-level rustling that shouldn't have been there. Swapping out RC4558 at IC303 with a replacement from DigiKey banished the last of the noise.

If you measure by length then try for 125mm . Your existing belt has probably stretched to around 130mm!. Alternatively, Fred at Marrs Communications can supply excellent belt kits. The belt is easy to change, almost a 2 second job..but you will need to remove the bottom panel as well to do it 'easily'. cheers, Martin ----- Original Message ----- From: Leon Koricki To: Talk about Nakamichi Cassette Decks Sent: Friday, February 13, 2009 8:28 PM Subject: Re: [naktalk] 581 rec problem I'm sorry for bad english, but what I was trying to said is what shorty1275nz wrote in his post.

I have already cleaned all the switches and controls. I have never had the machine serviced so it's probably a good idea to do what I can. Are there any guides on lubrication points for this machine? I looked on "tapeheads" and read about lubricating the capstans, is WD40 the correct thing to use for this purpose? Also there was mention of using White Lithium Grease on the transport guides, I have White Grease, can that be used? Also should the cam wheels for the mode motor be lubricated? Thank you to everyone who helped me before with my mode motor problem and any further guidance would be much appreciated. David.   ________________________________ From: David Wharton To: Talk about Nakamichi Cassette Decks Sent: Tuesday, 3 February, 2009 10:02:38 PM Subject: Re: [naktalk] Nakamichi BX-300 Problem Hello Ron, Thanks for your input. You are quite right, I had to push quite hard to get the worm gear back onto the shaft.  I don't know how it came off, but there it was lying at the bottom of the machine. The thing that confused me was looking at Graham's pictures on "tapeheads" of how to dismantle and repair the mode motor.  The pictures show 2 extra screws (above the screw used to remove the mode motor assembly from the machine) that secure a plate which is "L" shaped and aligns with the tip of the mode motor shaft which presumably stops the worm gear from coming away from the shaft! Also the tip of the worm gear has a round plastic cover over the tip of the motor shaft. My machine has neither the plate (or any sign of the 2 screw holes which hold it in place) or of the plastic cover at the tip of the worm gear! Would I be right in presuming that the photographs show a modified BX-300?  Maybe somebody's worm gear also became detached at some time! Have a look at the pictures and see what you think. http://www.tapeheads.net/showthread.php?t=2299 I am enjoying the deck right now, all appears to be working perfectly.

As a matter of fact, I am a bit confused about what happened to your deck. Not only have I never seen a worm gear fall off of its own volition, but deliberately removing it has always been a bit of a struggle. Just continue to use the deck in good health  :-). -- Ron David Wharton wrote: Hello Tom, So that's what you call it, the worm gear! I could not see anything else inside the machine that had fallen off apart from the worm gear, I did have a good poke around just in case. Anyway, the machine is all back together now (after many attempts at getting the cam wheels lined up correctly) and working as it always did.  I suppose at some point the worm gear will fall off again without the missing clip although it was a very tight fit to put the worm gear back on the shaft.  Is it OK for me to still use the machine knowing the clip is missing or could I damage it in any way? Thanks for letting me know, and I shall look out for a possible donor deck to get the missing clip. Regards, David. Hi Tech Service 2934 Nolensville Rd.

You can find White Lithium Grease and probably White Silicone grease at an auto parts store or a department store with a large atoumotive department you may also try a Restaurant Supply Distributor for the silicone grease, it's sold as "Food Grade Silicone Grease". Mineral oil can be found in almost any Pharmacy or Drug store or again in a large Department store. Just ask for Mineral Oil. The grease comes in cans or tubes and the Mineral Oil comes in a bottle. One bottle, can or tube is going to be a lifetime supply if you are doing an occasinal lube job on your tape deck. I hope this helps you in your endeavors.

Mineral oil is good for high speed metal to metal joints (which is why it is used for running in new car engines) Rgds, Bala Tom Brucker wrote: WD 40 is a bad lubricant, but a good cleaner.

I have already cleaned all the switches and controls. I have never had the machine serviced so it's probably a good idea to do what I can. Are there any guides on lubrication points for this machine? I looked on "tapeheads" and read about lubricating the capstans, is WD40 the correct thing to use for this purpose? Also there was mention of using White Lithium Grease on the transport guides, I have White Grease, can that be used? Also should the cam wheels for the mode motor be lubricated? Thank you to everyone who helped me before with my mode motor problem and any further guidance would be much appreciated. David.

You are quite right, I had to push quite hard to get the worm gear back onto the shaft. I don't know how it came off, but there it was lying at the bottom of the machine. The thing that confused me was looking at Graham's pictures on "tapeheads" of how to dismantle and repair the mode motor. The pictures show 2 extra screws (above the screw used to remove the mode motor assembly from the machine) that secure a plate which is "L" shaped and aligns with the tip of the mode motor shaft which presumably stops the worm gear from coming away from the shaft! Also the tip of the worm gear has a round plastic cover over the tip of the motor shaft. My machine has neither the plate (or any sign of the 2 screw holes which hold it in place) or of the plastic cover at the tip of the worm gear! Would I be right in presuming that the photographs show a modified BX-300? Maybe somebody's worm gear also became detached at some time! Have a look at the pictures and see what you think. http://www.tapeheads.net/showthread.php?t=2299 I am enjoying the deck right now, all appears to be working perfectly. Regards, David. From: Ron To: Talk about Nakamichi Cassette Decks Sent: Tuesday, 3 February, 2009 8:09:02 PMSubject: Re: [naktalk] Nakamichi BX-300 ProblemNot to be contrary, but IIRC, the worm gear is held in place by friction and does not require a clip to stay put. As a matter of fact, I am a bit confused about what happened to your deck. Not only have I never seen a worm gear fall off of its own volition, but deliberately removing it has always been a bit of a struggle. Just continue to use the deck in good health :-). -- RonDavid Wharton wrote: Hello Tom, So that's what you call it, the worm gear! I could not see anything else inside the machine that had fallen off apart from the worm gear, I did have a good poke around just in case. Anyway, the machine is all back together now (after many attempts at getting the cam wheels lined up correctly) and working as it always did. I suppose at some point the worm gear will fall off again without the missing clip although it was a very tight fit to put the worm gear back on the shaft. Is it OK for me to still use the machine knowing the clip is missing or could I damage it in any way? Thanks for letting me know, and I shall look out for a possible donor deck to get the missing clip. Regards, David. Hi Tech Service 2934 Nolensville Rd.

My observation : the 2 capstans on my BX300 will spin ene the deck is only powered on. It is the same with 680ZX. The BX300 left hub stops when tape is ended but the right hub keeps moving. I do not know whether it is the sole problem of the TIRE. But you can start by cleaning thoroughly the oxide off the Pinch roller FIRST. I am a newbie so don't take my word as gospel truth. Follow others instructions first. It is just my hunch.   I do not know whether changing belts will help in any way. I like also to know what is the best liquid to clean the pinch roller. Just thought that Isopropyl alchohol which is recommended contains alchohol so may affect the rubber of the pinch roller over time. Wonder if pure water (battrey water) is OK. Will water make the oxide rust I wonder.   ________________________________ From: "philbrick7 at aol.com" To: naktalk at naks.com Sent: Monday, February 16, 2009 3:36:44 AM Subject: [naktalk] Please help diagnose my BX-300 Hi all, there is something wrong with my BX-300 - please help!  Can anyone lead me in the right direction for diagnosing what might be wrong so I can determine if I should tackle the fix(es) myself or send it off for servicing.

One of the two in my deck start to turn into a piece of GUM. This deck is the little brother of the 5500M which similar to the 1000ZXL is the other deck that I know of that use 4 frequencies ( 1kHz, 5kHz, 7kHz and 14kHz ) in 32 steps with 0.25dB variation per step in its ATRS tape calibration system. The 3300M uses 3 frequencies though. Of course it lacks the Azimuth Calibration that the 1000ZXL enjoys.                                If anyone knows where I can locate one, much appreciated for that.

I do not recommend this to anybody with no knowledge of Dragon transport removal / reassemble experience. Or no understading of all small parts play a role in Dragon tape transport working Understand Dragon (pinch rollar) plastic guides on top of thiese rollars are extremely important for correct NAAC working. If you do not understand that these need correct placement back. Also please note that I have not come across a situation where these pinch rollars need replacement! Replacing rubber parts - sounds nice and simple like Orange cap replacement - but i know one Naktalk memeber desperately contacted me for further guidance after dis assembling part of transport and wondering how to proceed- basing on one ebay kit which tells that they give 10 page guidance etc with rubber belts! This warning comes after repairing more than 10 dragons last year. as usual there are naktalk members do not like this warning - However this is a warning only -before you plunge. I encourage members to do it if you have strong heart to wait and proceed / there is no hurry to make your Dragon play.

It is unlikely your hunch is valid, especially if the problem appears at the beginning of the cassette. . The problem is typical of a takeup issue. Most likely, either a dirty/worn rubber idler tire or a bad reel motor. In any case, dirty pinch roller is the last thing to check, not the first. To check, press PLAY with no cassette and lightly place a finger on the rotating takeup hub to gauge the torque by feel. If torque is too low (very light touch stops the hub) suspect a takeup issue.

The cam belt is too thick and too tight. It won’t allow the adjuster to move until the motor voltage is above 3v or so and the adjustment electronics will overshoot one direction, then the other trying to center. The right belt is slightly longer and much thinner. I use a 42mm x 1.2mm square belt (MCM # 42-160) and find that the auto azimuth (and level in the 682ZX) center up quickly and more accurately. The cam belt needs to be tighter and thicker since it is hauling the whole mechanism up and down and the exact stopping point is much more forgiving.

You will need to set up the guide heights with accuracy to ensure tape travel is optimised. It would be my personal recommended to recheck head alignment also as the mounting plate will most likely be removed in the process. Have a look at the service manual for the detailed steps involved. Some of the more experienced members may help with work arounds or quicker solutions - particularly if (as is likely) you do not have access to the original jigs or tapes. Take lots of digital photo's - particularly of the wiring runs before removal to assist with re installation.

I myself recently got a TD500 from ebay because there is this vendor selling refurbished (direct from Nak) and in the original box....I wanted play witht he effects of manual playback azimuth control and additonal tone controls (not found in home decks)....and since these decks were specifically designed for playback....happy to say the results are great since the deck is brand new and perfectly calibrated by Nak themselves. Now to powering - yes, since this runs on DC, I power it with an external DC power supply and it works like a charm....and I take the line level output and feed it to my home amp and it works like a charm.

(as i realized that i would never be able to put it back together after a while...) As everybody can guess i was the desperate guy who contacted Kannan off list!

In-Reply-To: References: Message-ID: <211ca5a30902161129v459caa06oc095c4cddc8386cf@mail.gmail.com> I recently replaced the five orange caps in a BX-1. I used the following parts from DigiKey: 9100pf 1600VDC 5% Vishay/BC metallized polypropylene film x1 .033uf 100V 5% Panasonic polyester film x2 .00039uf 100V 5% Panasonic polyester film x2 I believe that the originals are polypropylene film. I followed the advice on Scott Johnson's page to determine good replacement candidates: http://www.nakremotes.com/Geo/Scott_Nak_FAQ.htm#Orange%20Cap%20Disease Of the caps above, the 9100pf was the hardest to source in stock and the voltage rating is much higher than what the original Nak spec called for. This cap, in the bias oscillator circuit, is larger than the original orange cap so I had to build a clever standoff to get the cap to fit properly on the board. There is no audible difference between the original orange caps and the replacements. -jb On Mon, Feb 16, 2009 at 11:13 AM, Mark Hutchens wrote: > What capacitor would be a good replacement for orange cap disease?

My observation : the 2 capstans on my BX300 will spin ene the deck is only powered on. It is the same with 680ZX. The BX300 left hub stops when tape is ended but the right hub keeps moving. I do not know whether it is the sole problem of the TIRE. But you can start by cleaning thoroughly the oxide off the Pinch roller FIRST. I am a newbie so don't take my word as gospel truth. Follow others instructions first. It is just my hunch.   I do not know whether changing belts will help in any way. I like also to know what is the best liquid to clean the pinch roller. Just thought that Isopropyl alchohol which is recommended contains alchohol so may affect the rubber of the pinch roller over time. Wonder if pure water (battrey water) is OK. Will water make the oxide rust I wonder.   ________________________________ From: "philbrick7 at aol.com" To: naktalk at naks.com Sent: Monday, February 16, 2009 3:36:44 AM Subject: [naktalk] Please help diagnose my BX-300 Hi all, there is something wrong with my BX-300 - please help!  Can anyone lead me in the right direction for diagnosing what might be wrong so I can determine if I should tackle the fix(es) myself or send it off for servicing. My unit powers up fine, and when I try to play different tapes, it plays for a second then stops.  It sounds fine through phones for the second that it plays.  When I remove the tape there is a small loop of tape dangling on the right side.  The FWD or REV will not spin the tape.  It looks like it's trying, but doesn't have enough "juice" to get it to go, and it stops trying after a second.. When I remove the faceplate and press PLAY or FWD without a tape present but the door closed, the right cpastan(?) spins until I press STOP, the left capstan doesn't spin.  When I hit REV the left capstan(?) spins for three seconds then stops, the right capstan doesn't spin on REV. The other thing I notice when removing the cover is that the drive motor(?) at the very back of the tape mechanicals, the one with the belt going between two cylinders - when the BX-300 is powered on this motor and belt is spinning all the time, even at STOP.  There are two small prongs at the front that go through the cassette that are spinning all the time too - I assume powered by this motor/belt. Is that normal? In doing a bit of research it sounds like the idler tire might need to be replaced, which might account for some of the problems - and it seems fairly easy to fix.  But I don't know if that's the tip of the iceberg or not.

That is turn c.w. for a second or so  and then stop ?   You could have a mechanical problem or a logic board problem.     Here is a offer that may help both of us. See what you think    I also have a CR 7A. In brief, I am 58 year old electrical engineer. During my career, I also ran numerous Hi Fi service departments as service manager from the mid 70's and trained techs on the east coast and west coast to work on audio gear. etc. Then I moved into audio design. I still do lost of audio repairs on the hi end stuff as a hobby in my spare time. My specialty was high end audio recording equipment. Studio quality reel to reel and cassette decks.   Anyway, why I am sharing this info with you is because I am redesigning the logic board as a professional for my CR 7A because my girl friend accidentally splashed water into it. Destroying 2 of the 4 dedicated processors on that logic  board.   I am doing all the software for the processors on the CR 7A's logic board via reverse engineering. One of the processor's instructions  controls all the signal paths for audio amplifier and the calibration stuff. This particular processor  talks to a digital to analog converter chip. 8 channels worth of control each with it's own algorithm. With no documentation available, try to work these things out is trial and error and very time consuming. I have been trying to borrow another CR 7 A  so that I can hook up my multi-channel logic analyzer to it so that I can capture all the logic timing during the different functions. This would make my work so much quicker. It takes nothing from your deck just makes a copy of the logic pulses and records them for me.   This brings me to this offer. I live in South West NH. I would like to offer to diagnose and repair your deck for you free of charge. In return I will be able to capture a few helpful logic patterns into my analyzer so that I can complete my re design of my own deck. If your unit does not need mechanical parts..wear parts.. then this could work out the best for both of us.   If this is worth your consideration than I would like to ask you a few other questions about your deck's problems.   Regards   Ray Charlonne 603 532 6971 15 Squantum Rd Jaffrey, N.H. 03452 --- On Mon, 2/16/09, Paul Tombleson wrote: From: Paul Tombleson Subject: [naktalk] CR7A problem To: "Talk about Nakamichi Cassette Decks" Date: Monday, February 16, 2009, 5:44 PM I’m sorry that should have read CR-7A     Have an issue with CR-7 Transport will not engage (raise up)… push play/rewind/forward and nothing happens.

Most probable would be either a failure of one of the power supplies, or a dead spot in the control motor. A technical savvy owner would own a meter for measuring voltages and the ability to determine if (and which) supply is bad, but few would be able to dig down to the component level to fix it. Many here are capable of checking the control motor and fixing it, if bad. If you are unable (or unwilling) to delve into the deck, do send it to a good tech -- the CR-7 is one deck worth keeping. I see that Ray has offered to fix your deck, free of charge. By all means, grab this opportunity.

Normally, I don't post much here in quantity, but I read EVERY digest.;-) About Jeff at ESL....if you want a uncompromising, great restoration, by all means use ESL. Consider though, Jeff has a fair number of un-restored machines sitting on shelves, waiting for full restoration (he told me this on the phone). Those would therefore serve as your 'base unit'.

'Probably' you'll save yourself some $ and still get a proper working Nak deck. A lot depends of course, on how much you paid for the deck up front. Finally, there is a matter that concerns us all a a 'Nak community'. Recently, over at the Tape Asylum, I became the unwitting defender of Tom B. Let me explain; someone started a thread over there in which he praised Tom B (although he never used Tom's name, it was obvious whom he was referring to). This poster said Tom B had worked on a number of his decks and he (the OP) was more than happy with the results. (Remember this point, because that's how & why the thread was started) OK....I chimed in that Tom B takes a lot of flack sometimes, but that his advice on Naktalk was invaluable and I believed him to be a good egg. Nowhere did I ever say that Tom B had ever worked on any of my decks. Unfortunately, this drew from the woodwork, a poster named Rick/Rich. He proceeded to spin a tale of woe about Tom B and a certain 'Dragon deck' that Tom B serviced for him. When I challenged him to elaborate on the facts, he turned the whole accusation against me for defending Tom B. I stated that in the two some odd yrs @Naktalk, I never heard anyone say anything bad about Tom B other than his turnaround time was slow. No one that is, except this poster.....who produced a rant one day on Naktalk about Tom B. He claimed he never said anything about his shipping damaged Dragon on Naktalk. I found his original Naktalk post in the archives and pasted it over there on Asylum for all to read. After that, the thread became nothing but a series of  ad hominem attacks. Rick/Rich mentioned “others” as well who have been burned by Tom B. I challenged him to produce the “others”. No one came forward except Mike here, who is also kingseiko on Tape Asylum. Mike didn't feel the need to voice or justify his claim either of being a wronged “other” and also reduced his comment to a personal attack. Any lengthy debate or argument over @Tape Asylum always brings in my nemesis, "Tandberg Ray” (Some of you may remember him here @Naktalk-he followed me in and without any facts whatsoever, tried to post that Andy P was a country hack.) At this point I quit posting on the thread, because it had become nothing more than ad hominem attacks, mostly now against me. Rick/Rich and "Tandberg Ray" continued to have fun riding a dead horse, even though the horse was gone. Moral here is:If you have creditable (non-hysterical) experience with a Nak tech, for the sake of ALL of us, please post them! How are we to know as a community, who is reliable and who is not, if you don't post your experiences? I'm not asking for anybody to be slandered, just stay with the true facts as they happened and let the tech respond if they choose to-simple. For all you EE's that want to service your own decks, great! However, for the rest of us 'Joes' that rely wholly on techs, please air your praise or grievances ( whichever the case may be), respectfully and without the use of personal attacks. In conclusion, I suggest that the wronged “others” out there, grow some balls and post the facts of their grievances. And for the love of God, don't be persuaded by the 'winner' of an ad hominem attack as to who should service your decks.;-) BTW, I talked to Tom B about this in private email (before I posted anything), out of respect for all he's contributed here.

It would be greatly appreciated by everyone, I am sure! -------------- Original message from LENA WONG : -------------- To all the Members of this Forum: I am Mike and I am also use the name "KingSeiko" in Tape Asylum to voice my narrow opinion(s) related to Cassette Deck and Technologies. I know very little in this area and I am here and there to listen as well as to learn this lost art. I never spoke or act like an authority if any member can recall my past messages. Throughout my membership over this forum as well as over Tape Asylum, I read and occassion respond to others's published messages but I NEVER POST PERSONAL ATTACK MESSAGE to anybody. I respect every other's opinions and I believe everybody has the right to voice his/her opinions in a open forum. I join these two forums as a cassette tape lover but I NEVER INTEND TO BE A JUDGE AND/OR JUROR on others people's issues and I strongly believe that I DO NOT NEED to present any of MY OWN PERSONAL ISSUES to somebody who would like to act like a JUDGE/JUROR as well. I maynot agree with somebody's opinion/statement in the past BUT I NEVER SAY THEY ARE WRONG even though I only believe what my pair of not so good ears could hear but not based on what other people said so and so. If any member(s) would like/interest to review the original thread from what the below author wrote, they should go to Tape Asylum and find out themselves. What the below author's encounter with others is none of my business anywhere/anyway.

To: naktalk at naks.com Date: Tuesday, February 17, 2009, 6:36 PM I apologize in advance for this long posting. Normally, I don't post much here in quantity, but I read EVERY digest.;-) About Jeff at ESL....if you want a uncompromising, great restoration, by all means use ESL. Consider though, Jeff has a fair number of un-restored machines sitting on shelves, waiting for full restoration (he told me this on the phone). Those would therefore serve as your 'base unit'. To me, that takes the worry and frustration out of dubious ebay/craigslist sellers who advertise “as is” or “working perfectly-when in many instances, the deck hasn't recorded or played back a whole cassette in over ten yrs! Now....for those of us that insist on going the ebay/craigslist/estate sale route, you can also consider going with a tech here like Willy H, Andy P of Tom B (if in the States). 'Probably' you'll save yourself some $ and still get a proper working Nak deck. A lot depends of course, on how much you paid for the deck up front. Finally, there is a matter that concerns us all a a 'Nak community'. Recently, over at the Tape Asylum, I became the unwitting defender of Tom B. Let me explain; someone started a thread over there in which he praised Tom B (although he never used Tom's name, it was obvious whom he was referring to). This poster said Tom B had worked on a number of his decks and he (the OP) was more than happy with the results. (Remember this point, because that's how & why the thread was started) OK....I chimed in that Tom B takes a lot of flack sometimes, but that his advice on Naktalk was invaluable and I believed him to be a good egg. Nowhere did I ever say that Tom B had ever worked on any of my decks. Unfortunately, this drew from the woodwork, a poster named Rick/Rich. He proceeded to spin a tale of woe about Tom B and a certain 'Dragon deck' that Tom B serviced for him. When I challenged him to elaborate on the facts, he turned the whole accusation against me for defending Tom B. I stated that in the two some odd yrs @Naktalk, I never heard anyone say anything bad about Tom B other than his turnaround time was slow. No one that is, except this poster.....who produced a rant one day on Naktalk about Tom B. He claimed he never said anything about his shipping damaged Dragon on Naktalk. I found his original Naktalk post in the archives and pasted it over there on Asylum for all to read. After that, the thread became nothing but a series of ad hominem attacks. Rick/Rich mentioned “others” as well who have been burned by Tom B. I challenged him to produce the “others”. No one came forward except Mike here, who is also kingseiko on Tape Asylum. Mike didn't feel the need to voice or justify his claim either of being a wronged “other” and also reduced his comment to a personal attack. Any lengthy debate or argument over @Tape Asylum always brings in my nemesis, "Tandberg Ray” (Some of you may remember him here @Naktalk-he followed me in and without any facts whatsoever, tried to post that Andy P was a country hack.) At this point I quit posting on the thread, because it had become nothing more than ad hominem attacks, mostly now against me. Rick/Rich and "Tandberg Ray" continued to have fun riding a dead horse, even though the horse was gone. Moral here is:If you have creditable (non-hysterical) experience with a Nak tech, for the sake of ALL of us, please post them! How are we to know as a community, who is reliable and who is not, if you don't post your experiences? I'm not asking for anybody to be slandered, just stay with the true facts as they happened and let the tech respond if they choose to-simple. For all you EE's that want to service your own decks, great! However, for the rest of us 'Joes' that rely wholly on techs, please air your praise or grievances ( whichever the case may be), respectfully and without the use of personal attacks. In conclusion, I suggest that the wronged “others” out there, grow some balls and post the facts of their grievances. And for the love of God, don't be persuaded by the 'winner' of an ad hominem attack as to who should service your decks.;-) BTW, I talked to Tom B about this in private email (before I posted anything), out of respect for all he's contributed here.

I also read most every edition of Nalktalk.. Yes, I posted about my very bad experience with Tom, and also mentioned that I was not alone. My problem, was your putting my post down, even though you have NO personal experience with Tom working on any of your equipment. It was easy to see, that as with this post, you just crave attention. You posted in that thread, as if your some sort of "authority", you "demanded" proof, and that the "others" must come forward... very strange, indeed, when you have NO PERSONAL experience with Tom's work.. the only "experience" you added, was that Willy had worked on your gear. >From the negativity towards you by the other 2 posters, it was obvious to me that this was something you commonly engage in and that you have some "need" to draw attention to yourself.. you have some sort of "inferiority complex" so you must be the "Drama Queen" of the Forum, such that you are being now... I didn't have to come up with any "names" or "proof", I told my personal experience and noted that others had similiar. As for the "growing balls", I find that statement should be directed at you, Drama Queen,as you seem to want to continuously draw attention to yourself, and especially about something you have NO personal experience about...

Message-ID: <0KFA001F82UTBLH9@vms173009.mailsrvcs.net> Tom, I have to concur with you on these ideas. It should be low key and a list of qualified people shouldn't include a 'grade system'. A few months ago, I was asking about general service needs for my Dragon. You actually recommend a place in Cambridge. Due to a lack of money and no really need to get it done at this point, the recommendation was well appreciated and noted. Ron wrote a great response that while he likes the 'tough' jobs, he doesn't carry the necessary gauges to properly align guides, heads, etc,.... That's the kind of info that would interest me and then I'd be able to make my own decision if he would fit my needs. Most, if not all, qualified people on this forum, I believe, would be honest enough to say the type of work they do, not do, prefer to do and love to do!

Yes, when I simply powered the deck on (at idle), the tension is 11.65 V; very stable for 30 minutes (the capstans were on rotation by themselves) Then I played a cassette and indeed the tension droped to 10.69 V (not 11.69 as you wrote) So am I right saying the DD motor behaves (so far) in a normal way? one month ago, when I performed the same measure, it was (from memory) 11.05 V N.B: again, this morning, with deck "cold", it started with no problem.

Although I had to "wait," I was happy with the service that I received from "The Nak Guy In Tenn" (Tom) and still am. Why? Well, that "681ZX is the cassette deck from hell." I paid if memory serves me correctly $1600.00 for it brand new. It worked 6 months and then it had to back to Nakamichi for service. On and on and on (get the picture?) and on it went. During the time that I have owned that deck I have spent almost $2000.00 on it, getting it fixed for one thing or another. Finally, I brought a brand new CR7A, which has been a rock solid machine ever since I've owned it. I have spent approx $500.00 on it during the entire time that I have owned it for these pass 18 years. Back to the point, that 681ZX had been sitting in my audio room for almost 15 years in a non functional condition. Tom got it and my other EBAY CR7A "FULLY FUNCTIONAL" with shipping back to me for $147.00. So... Damn right I'm happy with the service and the "wait." Could things have been done better, yeah. I could of fixed them myself. Oh craps, I don't work that cheap. I charge a lot more for what I do, but... and get this, I don't know how to do fix Naks. My intention for starting that thread was to say something positive about what Tom did for me. I consider what he did to charity work. I was wondering how in the heck could he stay in business "working for peanuts?" However, that is none of my business and my hat is off to him. After writing the thread, I checked it a day or two later and I had one response which was positive. Then I checked last week and dang, it was ridiculous to say the least. Oh well I'm too busy for all this, I have to go listen to my new deck, THANKS AGAIN TOM.

I missed that. If the voltage dropped to 10.99V (as opposed to 11.69V), it means the motor current went up. This is as expected, but in this case, it's too high. The numbers mean that the motor current is 63.5mA at idle (high, but not dramatically) and is 234mA when playing. The latter is definitely very high. Could easily be caused by a mechanical problem. I know you already measured the 5.6Ω series resistor and found it good. The above currents are based on this value, so maybe you want to check it again. If correct, I wonder whether your new driver IC is still good. -- Ron From gabrenas at math.utah.edu Thu Feb 19 20:14:27 2009 From: gabrenas at math.utah.edu (Victor Gabrenas) Date: Thu, 19 Feb 2009 12:14:27 -0700 Subject: [naktalk] BX300 cabestans do not rotate on powering on AGAIN!!!

In response to Kevin's post regarding the whupping he took on Tape Asylum regarding our resident techs and the call for members' experiences with them, I wanted to say something about my own dealings with at least 3 of them. I'll begin with Jeff at ESL. He and his crew have been nothing but straightforward in my dealings with them. Sadly, of the two decks that I've sent to him, neither have been practically repairable so I can't vouch for his work but there are many more who can. Next in order of my experience is Andy. I purchased an RX-202 that he reconditioned and was selling. When I first recieved it, I though that one channel was out when recording and that the dolby C indicator light wasn't working. Both of these things proved not to be true. To my embarrassment, it was just my lack of familiarty with the controls.

Message-ID: <499E6D84.2080408@univ-rennes1.fr> Let's consider it is a mechanical problem: Without a cassette, the only mechanical difference between "at idle" and during PLAY is the friction on both capstan shafts generated by the pinch rollers: could it be that the latter are more difficult to spin that normal ? I am thinking about this because in both cases, either at idle or in PLAY, the capstans are on rotation, and if the friction of the belt was too high, I should not measure the nominal value of 11.7 V at idle? If the drop of voltage is too important upon PLAYING, this should be generated by a new feature that works only during PLAY, and the only thing I can think about is the pinch rollers. do they usually need a drop of oil?

Obviously, if anyone reads my postings, I wasn't trying to "hear myself talk", or be "JUDGE & JURY", but trying to get to the bottom of tech grievances and develop (somehow), good tech ratings. No, I haven't had any business dealings with Tom B, but I love to read his advice here. However, I had Andy P work on two decks for me and Willy H work on two decks for me, so I'm not "without experience" in these matters. And I've used other techs besides those two. It's pretty easy to see who was bitter and using ad hominem....but Wouter says I'm not suppose to say anymore, or I lose my membership here. You can go into Tape Trail @Asylum and read the whole thread, if interested-'nough said.  It would be a great thing here if we had some sort of attached or pinned page with Nak techs available and rated by their customers (with comments). These guys work really hard at what they do and deserve recognition.  I can't really speak for Andy P, but I'm guessing he doesn't post here anymore because of past flame attacks....Andy??

Although I had to "wait," I was happy with the service that I received from "The Nak Guy In Tenn" (Tom) and still am. Why? Well, that "681ZX is the cassette deck from hell." I paid if memory serves me correctly $1600.00 for it brand new. It worked 6 months and then it had to back to Nakamichi for service. On and on and on (get the picture?) and on it went. During the time that I have owned that deck I have spent almost $2000.00 on it, getting it fixed for one thing or another. Finally, I brought a brand new CR7A, which has been a rock solid machine ever since I've owned it. I have spent approx $500.00 on it during the entire time that I have owned it for these pass 18 years. Back to the point, that 681ZX had been sitting in my audio room for almost 15 years in a non functional condition. Tom got it and my other EBAY CR7A "FULLY FUNCTIONAL" with shipping back to me for $147.00. So... Damn right I'm happy with the service and the "wait." Could things have been done better, yeah. I could of fixed them myself. Oh craps, I don't work that cheap. I charge a lot more for what I do, but... and get this, I don't know how to do fix Naks. My intention for starting that thread was to say something positive about what Tom did for me. I consider what he did to charity work. I was wondering how in the heck could he stay in business "working for peanuts?" However, that is none of my business and my hat is off to him. After writing the thread, I checked it a day or two later and I had one response which was positive. Then I checked last week and dang, it was ridiculous to say the least. Oh well I'm too busy for all this, I have to go listen to my new deck, THANKS AGAIN TOM.

My 202 was repaired by ESL lab and though was expensive, it was very well done. Thanks to Jeff. In addition, Andy P calibrated/repaired my other decks (dragon is next) and he has done a excellent job on my 505, 303, CR2A; HK CD491 and another Technics. I strongly recommend Andy P as well as ESL labs. I extend my thanks to Andy P and Jeff for all their hard work as well as to Naktalk management for keeping this forum alive and interesting. I appeal to all the contributors and readers to respect each other's view and learn from others experiences.

Message-ID: <499EC413.2050405@otenet.gr> I just received a T-100 bought from ebay Germany...It looks and functions quite well (have not done any testing yet) but i need some experts advice on how to make sure the unit is in good working order...I have printed both owners and service manuals from Nak Wiki and i am in the process of reading, especially the deck part which interests me more, but i guess there must be a way of checking the unit for consistency and accuracy of its readings within specs.......I would very much appreciate any inputs you may have on the matter......I know that diagnosis is not enough for the decks, but at least i will be able to tell which one needs some serious service, as i have no other jigs or special gear for any kind of serious alignment..... If more test equipment are needed for the evaluation of my T-100, then i can always refer to a good friend who is a qualified tech in servicing hi end (and not only) audio gear.

When I opened the deck, I realized it was true as it was easy to see that the electric wire missed the "plastic link" (this dammed poor english!) that hold it to the PCB board.

Already one old member had left Naktalk in disgust. If you want ratings go to ebay and rate Bringing this type of Tech ratings will cause most of the techs here to even stop work on Nakamichi repair work. Already it does not pay unless you take up large amount of work. and we know few who does regular work. It is more than enough to give links of techs. Please contact members privately if you want to know their experience if you need. You also know who is doing what from their postings Please avoid converting this site to another audio asylum where anybody says anything goes. Already good old members have left Naktalk due to such fights and personal attacks just for their opinions.

Despite the difficulties of the past (as i followed them the past 3 years) and the fact that we are all individuals with different characters, ethics and religions the site has prove itself to be on top of all that and kept growing bringing new NAK funs from all around the world who seek for advice and want to discuss /exchange ideas on how to maintain their decks...... Wouter has the last word -of course - but i am almost certain he will do the best to maintain this forum unaffected from commercial interests.....

That will tell you if the problem is on the display board or on the auto azimuth board which is where the meter drive circuit lies. If the problem is on the display board, suspect the mute transistors Q101 or Q201. If the problem is on the auto azimuth board you'll need an oscilloscope to trace the signal flow and determine the bad component. Could be IC701 or IC 901.

I put a new TDK SAX 90 (I mean a good quality tape) and after 10 to 15 minutes, I heared the tape slowing down and down until stop just like before I changed the motor driver one month ago I opened it again on the bench and monitored again the voltage: IDLE: 11.50 V /PLAYING (empty):10.20 V You realize what I though: Oh sh..!Motor driver screwed again!!! And indeed, as soon as I touched on of the flywheel, the DD motor stopped ... Then I played with the take up roller again to check it : it was free. Put it back on PLAY as suddenly, I was able to feel the motor stronger and I measured IDLE:11.71V / PLAY: 10.99V How can it be that the problem seems reversible: when measuring 11.50 V at idle, I would have sweared it was off! Can th driver motoe has a thermal and/current security??? As the belt seems not too tigth. the rollers are really ok. The springs: honestly, I don't know, seems normal. However, how could a spring become stronger, you would expect it to become looser with time? I am back again with the idea that the oil I used was may be too thick , or simply not th correct one (I mean clock or sewing machine oils are really ligth in comparison).

If your idea is the consensus of the group, then I'm all for it. It's a very passive, innocuous way to get all the techs listed and quite a bit of their info besides. And I like the idea of contacting customers OFFLINE, good form. As far as "commercial" interests, I think most of the techs we know (in the States), do Nak repair as a hobby or part time in retirement. Technically, if they take money for repair they are professionals and in a sense providing a commercial service, but in the most broad use of the word "commercial".

I would be in favor of people volunteering what they do, what they want to do, what equipment they do have and their estimate turnaround time for standard services, ie; belts, idlers, no parts involved calibrations. Naks could have a registry of these techs and their services but former customers could leave their names for contact. In other words, I used Hans Greitel to calibrate my Dragon. All I would put in his 'guestbook' is my name and some contact info. Then if someone else wants to use Hans Grietel but is curious about MY experience, they would contact me OFFLINE to get my personal situation with Hans. Not my reports of how someone else used Hans.

To service the bearings, I remove the capstans and pass through the bearings a string drenched in a strong solvent. I repeat until it comes out clean. After letting the solvent evaporate, I put *light* machine oil on the bearings (both front and rear) and leave it there a for a few hours. The sintered bronze bearings are supposed to be absorb a small amount of the oil. I repeat several times. I then wipe the outside of the bearings, clean the capstans shafts and reassemble. I add a tiny drop of oil to the bearing before replacing the washers on the capstans then clean the capstans again. I do the above every two or three years (I listen to cassettes reasonably often). The first signal to do it again is when I can actually hear wow (if I can hear it, it's too high). -- Ron boitrel wrote: > > I know you won't believe me but these are new facts: > > After my last series of measurements, I reassemble the deck and put it > back on the shelf to simply enjoy music! > > I put a new TDK SAX 90 (I mean a good quality tape) and after 10 to 15 > minutes, I heared the tape slowing down and down until stop just like > before I changed the motor driver one month ago > > I opened it again on the bench and monitored again the voltage: IDLE: > 11.50 V /PLAYING (empty):10.20 V > > You realize what I though: Oh sh..!Motor driver screwed again!!! > > And indeed, as soon as I touched on of the flywheel, the DD motor > stopped ... > > Then I played with the take up roller again to check it : it was free. > Put it back on PLAY as suddenly, I was able to feel the motor stronger > and I measured IDLE:11.71V / PLAY: 10.99V > > How can it be that the problem seems reversible: when measuring 11.50 > V at idle, I would have sweared it was off!

Already it does not pay unless you take up large amount of work. and we know few who does regular work. It is more than enough to give links of techs. Please contact members privately if you want to know their experience if you need. You also know who is doing what from their postings Please avoid converting this site to another audio asylum where anybody says anything goes.

You certainly do not want it in the bearings. 'Sewing machine oil' is a catch all name for a *light* lubricating oil. The specific one I use is made by Boyle Midway*,* Inc. in New York. It's called '3 in 1 Household Oil' (I am not sure what the name actually means). The description states 'A high quality oil that can be used anywhere a light lubricant is needed'..

According to the meter my Dragon has approx. +-18 min. of azimuth correction which also corresponds to about 7khz at 3db loss and 6-7 db attentuation at 10khz. (all shown on the meter). I guess you could do the math if you know the distance between left and right tracks to determine at what frequency you could correct for 180 degree phase diff. I wonder what you are up to? Also, my Dragon seems to adjust azimuth while the tape is playing at any time it sees the need to, at any spot on the tape,no lights flashing! I have verified this (I think) by setting the azimuth to manual(switch on the meter)and dialing it in to find that the automatic correction (without lights flashing) is spot on! I may be getting fooled by the azimuth meter as it may be reading a response from the tape instead of a mechanical position. I was wondering if there was ever a consensus reached on how NAAC really works. Rainer S. ----- Original Message ----- From: Tom Brucker To: Ural Durusu ; Talk about Nakamichi Cassette Decks ; Talk about Nakamichi Cassette Decks Sent: Monday, February 23, 2009 10:21 AM Subject: Re: [naktalk] NAAC Ural, The easy answer is that the pre recorded tape has some fault that causes tape skew. The azimuth difference between centered an clicking is fairly small (anyone know how small? Will it correct 10kHz 180 deg. out of phase?) The Dragon overshoots NAAC correction sometimes. The circuit is driven on time constants, and presumes that most tapes are "close" to perfect. An easy test for your prerecorded tape is to remove the bottom cover, flip out the NAAC board, and unplug the 2 pin CN-5 connector after ejecting the tape. CN-5 is the azimuth motor lead. Now, test the pre recorded cassette and listen in mono. Do you hear pphase problems in reverse? If not, or if it is intermittent, carefully inspect the pinch guide arms for sticky grease and slow movement. If the supply side arm is slow to apply the proper pressure, the tape will skew in reverse for the first few minutes. Azimuth tapes generally have a larger tape pack to reduce skew, and this may explain why the two tapes behave differently. tom brucker -----Original Message----- From: Ural Durusu Sent: Feb 22, 2009 3:21 PM To: Talk about Nakamichi Cassette Decks Subject: [naktalk] NAAC Willy, I have one more question with the DRAGON NAAC system.

You can replace Q303 with a BC640 and the npn transistors with BC639's.

They are OK. They do rotate easily without belt : the supply one is absolutely silent (I cannot hear anything with head at 10 cm) , although on the other one (the take up one), you can hear a "little something due to some kind of very very light friction but don'y know f it is significant". However, when you give it a twirl for a quarter of revolution (about 45 °); it keeps rotating for about 3 revolutions...so I guess it's also ok But While testing the capstans, I also pulled them back a little bit, and once bak in place, this has released the washers which are located in the front on each shaft and I performed again the mesurments: idle: 11.71 V - 11.73 V  playing: 11.06 V - 11.07 V : I had never red these values before. May be the two washers were to strongly pushed back on the shaft and induced some friction. playing with the same cassette that before at the same REWIND location : 10.99 V- 11.00 V (again never red these before). So may be that was the point? Do these last values seem more reasonable?I never push those washers snugly against the bearing. It seems pulling them back did reduce friction.

The cassette drawer and turntable make the access more difficult. If you are not handy and used to working on electronics, I highly suggest you find someone who is. There are many professionals on Naktalk that can help you. Basically, here's what I did to get the idler tire on my RX-202 back in order: 1) Remove cover 2) Remove faceplate (this allows you easier access to the next few steps) via screws at top 3) The goal is to remove the backplate that sits directly behind the cassette. The idler you need to clean or replace lies behind this backplate between the two reel tables. Remove the two screws at the bottom corners of the backplate. 4) Look to the right of the transport. There's a vertical black metal plate held on by two screws. It holds a vertical plastic swing arm that provides tension to the cassette when loaded. The plastic arm has protrusions on each end that fit into holes. The top hole is in the metal plate I am mentioning. 5) Carefully remove the spring from the plastic arm using a tweezers or small screwdriver. Leave it in the machine connected on the other side. 6) Remove two small philips head screws holding the metal plate. If the transport is open you should be able to pull the metal plate out the front. Carefully remove the plastic arm, too. 7) At this point you should be able to follow standard idler replacement because the backplate will come off. The standard procedure is documented on the ES Labs site: http://www.eslabs.com/idler.htm Cleaning the idler as mentioned may help, but you may also need to replace the idler tire entirely. The ES Labs site tells you how to do this. 8) Put everything back in reverse order (metal plate goes back in the transport via the front). I was able to get the spring back on the plastic arm using a tiny pair of pliers and a jeweler's screwdriver - that was the most difficult part of reassembly. You have the plastic arm and metal plate on the other side to guide you - the arm needs to be in a specific position aligning with a small metal "button" on the drawer. 9) The thin metal backplate needs to be put back in a very specific way, lining up with grooves at the top of the transport. If you don't get it back in there correctly, you will suffer azimuth issues as the cassette will not be held in the right position during play/record. Good luck. -jb On Tue, Feb 24, 2009 at 3:49 PM, wrote: > Hi again Ali. > I appreciate your recent reply regarding the issue with my 202. > I did what you said...but only got as far as taking the top off. > What do you mean "on top of the cassette compartment?" > Do I have to remove anything else to access that compartment to find the > small electric motor and rubber idler wheel and the brass bushing you speak > of? > I see a bunch of motors, I see the belt, I even see a motor with a screw an > gear opposite  the drum, but nothing like you speak of.

Also tested and cleaned the relay in one of these plug in boards still no luck! The 400hz test tone is working great! as are the major functions like fast forward, rewind, pause, play a. Also which will be the best source to get replacement belts and the rubber idler, looking for a supplier that can ship fast and the belts are of good quality matching the original belts and the rubber idleer.

Check to make sure the tape path is thoroughly clean and that the machine basically records and plays back on both channels. Then check to make sure the auto azimuth block is free and working properly. You can unplug the motor connector from the circuit board and test to make sure it will travel freely with 3 volts or less. If not the problem could be as easy as a good auto azimuth block cleaning and a belt replacement. It could also be that the tape path needs to be realigned. If the azimuth of either the play head or record is far enough out of calibration the auto azimuth range won't be able to extend far enough to calibrate properly.

The only drawback, it sat in a closet in its original box for 6+ years. The cure..........running it. It was tough, but somehow I worked through it. I started with coffee and a bagel yesterday morning and listened to Copeland, later on I roughed through a corned beef sandwich and listened to some of The Blue Note Catalogue, and finally later on in the day suffered with a couple of burgers and a glass of V-8 juice and listened to some Dylan tapes which took me back to my college years. Hard, but someone had to do it. Again thanks for all your help, and I am sure I will be back with more questions. rick **************Get a jump start on your taxes.

I'm afraid due to my lack of lack of skills, I took the easy way out but bottom line...it worked. As I mentioned, the unit was in perfect condition when purchased. The only drawback, it sat in a closet in its original box for 6+ years. The cure..........running it. It was tough, but somehow I worked through it. I started with coffee and a bagel yesterday morning and listened to Copeland, later on I roughed through a corned beef sandwich and listened to some of The Blue Note Catalogue, and finally later on in the day suffered with a couple of burgers and a glass of V-8 juice and listened to some Dylan tapes which took me back to my college years. Hard, but someone had to do it. Again thanks for all your help, and I am sure I will be back with more questions.   rick Get a jump start on your taxes.

The playback is fine in both channel. Also all the light for tape selection are lit!  all the time moving the tape selector to ex, sx or zx setting has no effect! I have replaced all the orange pp caps in all the boards except the two on the mother board which I dont have the correct value at present but I dont think replacing these will make any difference. Also have replaced the RC 4559 and RC 4558 op amps in the bias osc, rec and playback amp boards but still the problem is there. Also tested and cleaned the relay in one of these plug in boards  still no luck! The 400hz test tone is working great! as are the major functions like fast forward, rewind, pause, play a. Also which will be the best source to get replacement belts and the rubber idler, looking for a supplier that can ship fast and the belts are of good quality matching the original belts and the rubber idleer. Any kind help! will be greatly appreciated!  Thanks!  With Best Regards!  Ali   In a message dated 2/25/2009 3:40:58 A.M.

It doesn't 'encode' anything on the tape to 'decode' later, correct?  And if that's true, then using it again on playback after using to record, serves what purpose? But....when I'm recording and I'm set at Source, everything sounds beautiful & clean. However when I switch to Tape, I hear hiss, although everything else sounds fine (music wise). That should be telling me that there is no encoding/decoding going on, correct? Yet when I play the recorded tape back, it sounds fine, without hiss (albeit the SNR-1 is still in the circuit). However, when I hit Bypass (on the SNR-1) at this point, I think I should be hearing some of that hiss again...I don't, so what's going on?

Have your tech clean and lube the azimuth alignment unit. Make sure that the dried up lube at the end of the screw drive (where it rests at the plastic catches) is replaced. No other lube is necessary. Do not lube the threads on the screw drive because it's only going to accumulate dirt and cause problems. It has to be cleaned and that's it. Install a fresh belt and it is ready to go. Also have your tech check the Bowden cable (the blue coloured cable that causes the azimuth to changed). Make sure that it isn't bent or does not impede motion. This is another part where no lube should be applied. It is also better that your tech does a complete tape path alignment (including the azimuth alignment unit check) before declaring sucess. Regards, BG Kevin Rogers wrote: I have a problem with an otherwise near mint - low use Nak 682ZX. According to my Tech, it will go through the auto azimuth calibration sequence ( he can hear the motors etc and has watched the tones on his scope) but it will not finish the sequence and rewind to the starting point as it should. He says it seems the deck is not happy with its result :) Does anyone have any suggestions of what he could look at?

In my case it didn't matter, because much of the transport had dried grease and was pretty much frozen from neglect.  So yeah, while it can be done, most probably your transport has other problems as well.

It is likely to only be the idler tire that is passed its use by date, so why not just replace it using a good quality nak BX tire?...my Sansui's take the same tire as the BX series.. so that is good from a maintenance POV. Otherwise, your best bet is to get a CR-1 and break it for the necessary parts.

The Aiwa F series decks are seriously the decks to go for as far as Aiwa is concerned. Many know the Excelia and the XK-9000S better, but again this is more of a marketing thing. The F series decks pack a long list of features such as auto-calibration, flourescent meters, real-time/linear counter, auto- head demagnetizing etc, depending on the model. A complete list of features can be found on the vintage cassette deck website. Sound-wise, it has a very warm, pleasing sound with good soundstaging.

The chassis is pressed sheet metal and the wiring is a tangled rat's nest. The transport mechanism is incredibly complex and fragile.

The 1000ZXL and 700ZXL are quite different although they seem to spec out almost the same. The 700ZXL shares the same playback/Dolby board and a similar RAMM system with the 1000ZXL. Much of the transport related logic and auto-azimuth circuits are also similar though the circuity has been rather crammed into a smaller boards. One of the key difference is that that the ABLE system is very different from the the 1000ZXL. It isn't controlled by a micro-processor (although all available literature suggests that it does) but uses sequential logic made up of multiple logic circuits. The good news is that this is fixable as parts are plentiful. The bad news is that it can be a pain to troubleshoot! The auto-calibration uses only two frequencies 400Hz for level and 15kHz for the bias adjustment. A third frequency (7kHz) is used to linearize the EQ. This differs greatly from the 1000ZXL's ABLE computer which does use a micro-processor, and uses 4 different frequencies for a true calibration irregardless of tape type inserted. The 1000ZXL, in my opinion, is a more through system that features a micro-processor. The processor, is a 4-bit PMOS model that has seen widespread use in some of the best cassette decks made during the late 70s and early 80s. This include the Aiwa F series (990, 880, 660 etc) and Aiwa 6700, 6900 and 6900II. Sound wise, these two decks differ quite a bit. The 1000ZXL has a more bigger sound, with deep and wide soundstage. The bass is more deeper, perhaps thanks to its more generous power supplies. The 700ZXL sounds slightly closed in, and the bass is not as refined as it's bigger cousin. It does however have equally sweet highs and capable of bringing out the best out of pre-recorded tapes if azimuth is in sync, as with the 1000ZXL. With the amount of engineering differences, Nakamichi seems to have cut lots of cost, though this also results in differences in sound quality. The 700ZXL is however very close up there to the 1000ZXL. They however, don't seem to be build for longevity and chassis stiffness leaves much to be desired. One thing I would love is to have LP's LED upgrade kit for the control compartment illumination!

I couple of days ago I got my RX-505E out of storage and tried it out. I guess the usual stuff needs to be replaced such as cam motor belt and capstan belt. However, it seemed to me that reel motor was producing some kind of knocking sound (i.e. fast knocking when FF/RW and slow knocking when PB). Shouldn't the RX-505 be dead silent when in operation? I've looked at the reel moter there is reddish cardboard-like material covering the backside of the motor. Can the reel motor be cleaned if this material is removed? Another Thing, I recall that I had once accidentally dabbled with the Reel Motor Speed adjustment VR604. Does this have a significant impact on playback. Is there an easy way to adjust it to a proper setting?

One never knows what stimulating topics might turn up in this forum, and anything stimulating when you gotta work on New Year's Day with a sleep deficit resulting from the night before is to be applauded (just not too loudly, please) ;-) I've been following some of the comments relating to comparisons of characteristic sound of our beloved Naks, sometimes as related to high end decks of other manufacturers. In reading ddino77's post today, I can see I'll soon be "resurrecting" a favorite deck of mine for some comparison-listening... I, too, own an Aiwa 6900 Mk.II, as well as two of its predecessors, the 6900. They were all purchased new in the '70s, well before I got into Nakamichis. At the risk of veering too much OT in praising a non-Nak, I'd simply say that, at the time, I could not afford the high end Naks of the 1000 and 700 series, but was mightily impressed by the solid construction of those top-of-the-line Aiwas -- and, boy, were they h-e-a-v-y -- the very responsive transports, which provided audible fast search directly from Play, the double needle meters, which allowed one to view simultaneously, or separately, both VU and Peak characteristics of the music being recorded, the very capable F.R.T.S. tape tuning system, which allowed front panel optimizing of not only bias but level, to minimize the dreaded Dolby-B mistracking. It was also reasonably easy to get at the PB head azimuth while in Play to optimize dull-sounding tapes made on other people's machines. Oh, yes, they were indeed handsome brutes with their brushed silver front panels, and ergonomically very impressive as well. I used my 6900s not only for serious music recording, but also for production purposes in my studio -- hence the admiration of the audible fast cueing, super-fast winding, and the other features noted above, as well as their super-reliability. For a few years, I had two of these machines under daily timer control to record air-checks of my radio programs. And, yes, they did absolutely superbly with Type I C-120s. Please forgive the sentimental digression. The reason I found dino's post so stimulating is that, while I found my 6900's so satisfying in heavy usage, I guess I did not realize their sound could be described as smooth and tube-like in sound quality. My admiration for their sound was that, after doing the (manual) F.R.T.S. set-up, I could flip back and forth between input and tape while recording and hear NO appreciable differences between them. CD's, of course -- dare I say good CDs? -- did push the Aiwa's envelope, but only in S/N against very low level passages, as the 6900's had only Dolby-B NR. Even so, taking advantage of those fast responding Peak meters allowed the user to get the most S/N from any tape, up to the saturation point. And even there, as we analog folks know, the tape handled it very gracefully -- i.e., musically), kinda like, err, TUBES (Valves for you lot across the Pond). I can still listen to any number of cassettes, whether from vinyl or CD, made on those 6900s and smile. Broadly! Being a professional user of the cassette medium, still into the 90's, I could not resist the appeal of the Nakamichi CR-7A, in terms of nailing azimuth -- just so much more elegant to switch to mono and turn the 7's azi adjust knob till the high sounded identical, than sticking tiny screwdrivers into the 6900's. But even that did not diminish my love for using my three 6900 "tanks." So, the four decks existed side by side. A few years ago, the lust for Nakamichis I couldn't afford when new, especially the UDAR machines like the RX-505 and 202, led me to start purchasing some of these, as well as other Naks. There being only so much space in my studio, certain decks had to sit "in reserve" as the fleet grew. Thus, my trusty 6900II, after a thorough overhaul and tuning a few years ago, never got plugged back in. Yep, I've looked at it longingly, and as to the last repair's warranty...well, fugettabout it if anything escaped attention...or if the new rubber installed went south from disuse ;-) Well, I never said I was "smart." Just passionate about this lovely gear... While I'd always considered the 6900 and the 6900 II, the high-water mark of Aiwa, I later learned of the XK-S9000, which truly was their last fine deck. It even provided, in addition to Dolby-B and -C, Dolby's high-water mark in consumer NR, Dolby-S. Guess it was also their valedictory, as it came out when cassette was, in the eyes of most, passé. It was just as handsome as the 6900s, only in perhaps a more upscale way, with champagne colored front panel and high-gloss rosewood side panels. I also knew, from its published weight that there was a pretty good chance of its being as well-built as the 6900's. Well I found one in mint condition from a very meticulous seller on ebay, and it's doing sterling service as (currently) one of my most used decks. But -- finally, I hear y'all saying -- back to Nakamichi! As I stated in a previous post, the itch to have one Golden Age Nakamichi finally had to be scratched. And that led me to buy my 700 ZXE from that same meticulous seller. Due to an impossible schedule over the last several months, I felt it wiser to keep the 700 packed up until I could relax and really get to know it. So, thanks Dino! I now have some stimuating reasons in this New Year to unpack the 700 ZXE (guessing it's close enough in vintage to the earlier 700's that "tube-ish" might still apply!), and to pull the 6900 II off the reserves, and set them both up alongside the XK-S9000 for some comparison listening. Hey, ain't this hobby FUN? Enjoy the music, all, and Happy New Year!

Comparing it to later decks like the CR7 which has a similar auto-cal system, the 700ZXL does seem aged, clunky and complicated. But it still works! The Aiwa F series decks are seriously the decks to go for as far as Aiwa is concerned. Many know the Excelia and the XK-9000S better, but again this is more of a marketing thing. The F series decks pack a long list of features such as auto-calibration, flourescent meters, real-time/linear counter, auto- head demagnetizing etc, depending on the model. A complete list of features can be found on the vintage cassette deck website. Sound-wise, it has a very warm, pleasing sound with good soundstaging. The bass is not very low, nor does it posses extended highs. But this is a cassette deck that you can listen to for very long hours without tiring one's ears. I have a AD-F990 which has been in my house since '83. Tapes made on this deck 20 years ago, out-perform CDs today! Build quality is, sadly, downright cheesy. Drugstore quality? Right! The chassis is pressed sheet metal and the wiring is a tangled rat's nest. The transport mechanism is incredibly complex and fragile. It is becoming more difficult to maintain these decks due to the fragility and lack of parts. The AD-F, and earlier AD series decks however, have a charm of their own.

The 1000ZXL and 700ZXL are quite different although they seem to spec out almost the same. The 700ZXL shares the same playback/Dolby board and a similar RAMM system with the 1000ZXL. Much of the transport related logic and auto-azimuth circuits are also similar though the circuity has been rather crammed into a smaller boards. One of the key difference is that that the ABLE system is very different from the the 1000ZXL. It isn't controlled by a micro-processor (although all available literature suggests that it does) but uses sequential logic made up of multiple logic circuits. The good news is that this is fixable as parts are plentiful. The bad news is that it can be a pain to troubleshoot! The auto-calibration uses only two frequencies 400Hz for level and 15kHz for the bias adjustment. A third frequency (7kHz) is used to linearize the EQ. This differs greatly from the 1000ZXL's ABLE computer which does use a micro-processor, and uses 4 different frequencies for a true calibration irregardless of tape type inserted. The 1000ZXL, in my opinion, is a more through system that features a micro-processor. The processor, is a 4-bit PMOS model that has seen widespread use in some of the best cassette decks made during the late 70s and early 80s. This include the Aiwa F series (990, 880, 660 etc) and Aiwa 6700, 6900 and 6900II. Sound wise, these two decks differ quite a bit. The 1000ZXL has a more bigger sound, with deep and wide soundstage. The bass is more deeper, perhaps thanks to its more generous power supplies. The 700ZXL sounds slightly closed in, and the bass is not as refined as it's bigger cousin. It does however have equally sweet highs and capable of bringing out the best out of pre-recorded tapes if azimuth is in sync, as with the 1000ZXL. With the amount of engineering differences, Nakamichi seems to have cut lots of cost, though this also results in differences in sound quality. The 700ZXL is however very close up there to the 1000ZXL. They however, don't seem to be build for longevity and chassis stiffness leaves much to be desired. One thing I would love is to have LP's LED upgrade kit for the control compartment illumination!

I have never been able to repair the latter.

They were all purchased new in the '70s, well before I got into Nakamichis.  At the risk of veering too much OT in praising a non-Nak, I'd simply say that, at the time, I could not afford the high end Naks of the 1000 and 700 series, but was mightily impressed by the solid construction of those top-of-the-line Aiwas -- and, boy, were they h-e-a-v-y -- the very responsive transports, which provided audible fast search directly from Play, the double needle meters, which allowed one to view simultaneously, or separately, both VU and Peak characteristics of the music being recorded, the very capable F.R.T.S. tape tuning system, which allowed front panel optimizing of not only bias but level, to minimize the dreaded Dolby-B mistracking.  It was also reasonably easy to get at the PB head azimuth while in Play to optimize dull-sounding tapes made on other people's machines.  Oh, yes, they were indeed handsome brutes with their brushed silver front panels, and ergonomically very impressive as well.   I used my 6900s not only for serious music recording, but also for production purposes in my studio -- hence the admiration of the audible fast cueing, super-fast winding, and the other features noted above, as well as their super-reliability.  For a few years, I had two of these machines under daily timer control to record air-checks of my radio programs.  And, yes, they did absolutely superbly with Type I C-120s.    Please forgive the sentimental digression.  The reason I found dino's post so stimulating is that, while I found my 6900's so satisfying in heavy usage, I guess I did not realize their sound could be described as smooth and tube-like in sound quality.  My admiration for their sound was that, after doing the (manual) F.R.T.S. set-up, I could flip back and forth between input and tape while recording and hear NO appreciable differences between them.  CD's, of course -- dare I say good CDs? -- did push the Aiwa's envelope, but only in S/N against very low level passages, as the 6900's had only Dolby-B NR. Even so, taking advantage of those fast responding Peak meters allowed the user to get the most S/N from any tape, up to the saturation point.  And even there, as we analog folks know, the tape handled it very gracefully -- i.e., musically), kinda like, err, TUBES (Valves for you lot across the Pond).   I can still listen to any number of cassettes, whether from vinyl or CD, made on those 6900s and smile. Broadly!   Being a professional user of the cassette medium, still into the 90's, I could not resist the appeal of the Nakamichi CR-7A, in terms of nailing azimuth -- just so much more elegant to switch to mono and turn the 7's azi adjust knob till the high sounded identical, than sticking tiny screwdrivers into the 6900's.   But even that did not diminish my love for using my three 6900 "tanks."  So, the four decks existed side by side.    A few years ago, the lust for Nakamichis I couldn't afford when new, especially the UDAR machines like the RX-505 and 202, led me to start purchasing some of these, as well as other Naks.   There being only so much space in my studio, certain decks had to sit "in reserve" as the fleet grew.  Thus, my trusty 6900II, after a thorough overhaul and tuning a few years ago, never got plugged back in.  Yep, I've looked at it longingly, and as to the last repair's warranty...well, fugettabout it if anything escaped attention...or if the new rubber installed went south from disuse ;-)  Well, I never said I was "smart." Just passionate about this lovely gear...   While I'd always considered the 6900 and the 6900 II, the high-water mark of Aiwa, I later learned of the XK-S9000, which truly was their last fine deck. It even provided, in addition to Dolby-B and -C, Dolby's high-water mark in consumer NR, Dolby-S.  Guess it was also their valedictory, as it came out when cassette was, in the eyes of most, passé.    It was just as handsome as the 6900s, only in perhaps a more upscale way, with champagne colored front panel and high-gloss rosewood side panels. I also knew, from its published weight that there was a pretty good chance of its being as well-built as the 6900's.  Well I found one in mint condition from a very meticulous seller on ebay, and it's doing sterling service as (currently) one of my most used decks.   But -- finally, I hear y'all saying -- back to Nakamichi!   As I stated in a previous post, the itch to have one Golden Age Nakamichi finally had to be scratched.  And that led me to buy my 700 ZXE from that same meticulous seller.    Due to an impossible schedule over the last several months, I felt it wiser to keep the 700 packed up until I could relax and really get to know it.   So, thanks Dino!  I now have some stimuating reasons in this New Year to unpack the 700 ZXE (guessing it's close enough in vintage to the earlier 700's that "tube-ish" might still apply!), and to pull the 6900 II off the reserves, and set them both up alongside the XK-S9000 for some comparison listening.   Hey, ain't this hobby FUN?  Enjoy the music, all, and Happy New Year!   Steve Ember     From: ddino77 at bellsouth.net To: naktalk at naks.com Subject: Re: FW: [naktalk] Re:1000ZXL versus 700ZXL Date: Thu, 1 Jan 2009 03:22:04 +0000 IMHO the Aiwa AD-6900II compares favorably with the Nak 700II, for a smooth, tubish sound quality.

I also have an Aiwa AD-F990 cassette deck. It's mint. After I purchased it, I got a belt replacement / calibration / head alignment / speed control adjustment / tune up. I obtained it from the original owner along with the owners manual and the receipt. I believe it was $579 what he paid for it. The guy never used it. It even had the plastic wrapping on the cover! I still have not yet used it for recording purposes, but your input got me excited. I value it at $300, but am presently uncertain if I will sell it.

Comparing it to later decks like the CR7 which has a similar auto-cal system, the 700ZXL does seem aged, clunky and complicated. But it still works!   The Aiwa F series decks are seriously the decks to go for as far as Aiwa is concerned. Many know the Excelia and the XK-9000S better, but again this is more of a marketing thing. The F series decks pack a long list of features such as auto-calibration, flourescent meters, real-time/linear counter, auto- head demagnetizing etc, depending on the model. A complete list of features can be found on the vintage cassette deck website.   Sound-wise, it has a very warm, pleasing sound with good soundstaging. The bass is not very low, nor does it posses extended highs. But this is a cassette deck that you can listen to for very long hours without tiring one's ears. I have a AD-F990 which has been in my house since '83. Tapes made on this deck 20 years ago, out-perform CDs today!   Build quality is, sadly, downright cheesy. Drugstore quality? Right! The chassis is pressed sheet metal and the wiring is a tangled rat's nest. The transport mechanism is incredibly complex and fragile. It is becoming more difficult to maintain these decks due to the fragility and lack of parts.   The AD-F, and earlier AD series decks however, have a charm of their own.   Rgds, Bala   Kevin Fetner wrote: Hi Bala, Thanks a lot for that description/comparison-excellent! You're correct, the brochures don't do the differences justice. And yeah, I thought the A.B.L.E. system was controlled by a micro-processor...hmmmmmm.

The 1000ZXL and 700ZXL are quite different although they seem to spec out almost the same.       The 700ZXL shares the same playback/Dolby board and a similar RAMM system with the 1000ZXL. Much of the transport related logic and auto-azimuth circuits are also similar though the circuity has been rather crammed into a smaller boards.       One of the key difference is that that the ABLE system is very different from the the 1000ZXL. It isn't controlled by a micro-processor (although all available literature suggests that it does) but uses sequential logic made up of multiple logic circuits. The good news is that this is fixable as parts are plentiful. The bad news is that it can be a pain to troubleshoot! The auto-calibration uses only two frequencies 400Hz for level and 15kHz for the bias adjustment. A third frequency (7kHz) is used to linearize the EQ.       This differs greatly from the 1000ZXL's ABLE computer which does use a micro-processor, and uses 4 different frequencies for a true calibration irregardless of tape type inserted. The 1000ZXL, in my opinion, is a more through system that features a micro-processor. The processor, is a 4-bit PMOS model that has seen widespread use in some of the best cassette decks made during the late 70s and early 80s. This include the Aiwa F series (990, 880, 660 etc) and Aiwa 6700, 6900 and 6900II.       Sound wise, these two decks differ quite a bit. The 1000ZXL has a more bigger sound, with deep and wide soundstage. The bass is more deeper, perhaps thanks to its more generous power supplies. The 700ZXL sounds slightly closed in, and the bass is not as refined as it's bigger cousin. It does however have equally sweet highs and capable of bringing out the best out of pre-recorded tapes if azimuth is in sync, as with the 1000ZXL.       With the amount of engineering differences, Nakamichi seems to have cut lots of cost, though this also results in differences in sound quality. The 700ZXL is however very close up there to the 1000ZXL. They however, don't seem to be build for longevity and chassis stiffness leaves much to be desired.       One thing I would love is to have LP's LED upgrade kit for the control compartment illumination!       Rgds,   Bala ========---------------------------------------------------------========= Register your Nak today! http://www.naks.com/register ========---------------------------------------------------------========= Naktalk at naks.com mailinglist Maintain your account here: http://www.naks.com/mailman/listinfo/naktalk ========---------------------------------------------------------========= Life on your PC is safer, easier, and more enjoyable with Windows Vista®.

The XK series were built more to perform when compact discs were becoming mainstream. The sound is very much forward and lean, compared to the warmer and laid back sounding 6900s. The XK series decks had more attention to qualty and build compared to the AD-F series decks, which were of cheesy build and contained a rat's nest of wiring. Despite this, they still have a very good sound and made recordings that are of stirling quality 20 years later. The XK series decks have their transformers located outside the chassis, and spot seperate transformers for the digital and analog domains. This, and the multiple power supplies pay of with a really low noise floor and stunning dynamics, that become even more solid when Dolby kicks in. I have the XK009 (Excelia) which has DBX, it makes really really good recordings. During the late 80s, when the AD-F990 went in for service (due to the Dolby chip going south), some Japanese engineers were at the service center here in Singapore. My dad was able to talk to them and get their insights. The frank opinion was to let go of the AD-F990 and go for the Excelia. This was just before the XK9000 was out, and which is much better then the Excelia. However awesome and jaw dropping the XK009 and XK9000s sound, I am guessing that the ZXE is going to impress you much more then the XK9000s will ever do. The XK, when you close your eyes, make you remember that your have two speakers and you are playing cassettes. The ZXE, will sweep all those away and replace them with some real people with real instruments!

Due to an impossible schedule over the last several months, I felt it wiser to keep the 700 packed up until I could relax and really get to know it. So, thanks Dino! I now have some stimuating reasons in this New Year to unpack the 700 ZXE (guessing it's close enough in vintage to the earlier 700's that "tube-ish" might still apply!), and to pull the 6900 II off the reserves, and set them both up alongside the XK-S9000 for some comparison listening. Hey, ain't this hobby FUN? Enjoy the music, all, and Happy New Year!

Comparing it to later decks like the CR7 which has a similar auto-cal system, the 700ZXL does seem aged, clunky and complicated. But it still works! The Aiwa F series decks are seriously the decks to go for as far as Aiwa is concerned. Many know the Excelia and the XK-9000S better, but again this is more of a marketing thing. The F series decks pack a long list of features such as auto-calibration, flourescent meters, real-time/linear counter, auto- head demagnetizing etc, depending on the model. A complete list of features can be found on the vintage cassette deck website. Sound-wise, it has a very warm, pleasing sound with good soundstaging. The bass is not very low, nor does it posses extended highs. But this is a cassette deck that you can listen to for very long hours without tiring one's ears. I have a AD-F990 which has been in my house since '83. Tapes made on this deck 20 years ago, out-perform CDs today! Build quality is, sadly, downright cheesy. Drugstore quality? Right! The chassis is pressed sheet metal and the wiring is a tangled rat's nest. The transport mechanism is incredibly complex and fragile.

The 1000ZXL and 700ZXL are quite different although they seem to spec out almost the same. The 700ZXL shares the same playback/Dolby board and a similar RAMM system with the 1000ZXL. Much of the transport related logic and auto-azimuth circuits are also similar though the circuity has been rather crammed into a smaller boards. One of the key difference is that that the ABLE system is very different from the the 1000ZXL. It isn't controlled by a micro-processor (although all available literature suggests that it does) but uses sequential logic made up of multiple logic circuits. The good news is that this is fixable as parts are plentiful. The bad news is that it can be a pain to troubleshoot! The auto-calibration uses only two frequencies 400Hz for level and 15kHz for the bias adjustment. A third frequency (7kHz) is used to linearize the EQ. This differs greatly from the 1000ZXL's ABLE computer which does use a micro-processor, and uses 4 different frequencies for a true calibration irregardless of tape type inserted. The 1000ZXL, in my opinion, is a more through system that features a micro-processor. The processor, is a 4-bit PMOS model that has seen widespread use in some of the best cassette decks made during the late 70s and early 80s. This include the Aiwa F series (990, 880, 660 etc) and Aiwa 6700, 6900 and 6900II. Sound wise, these two decks differ quite a bit. The 1000ZXL has a more bigger sound, with deep and wide soundstage. The bass is more deeper, perhaps thanks to its more generous power supplies. The 700ZXL sounds slightly closed in, and the bass is not as refined as it's bigger cousin. It does however have equally sweet highs and capable of bringing out the best out of pre-recorded tapes if azimuth is in sync, as with the 1000ZXL. With the amount of engineering differences, Nakamichi seems to have cut lots of cost, though this also results in differences in sound quality. The 700ZXL is however very close up there to the 1000ZXL. They however, don't seem to be build for longevity and chassis stiffness leaves much to be desired. One thing I would love is to have LP's LED upgrade kit for the control compartment illumination!

When I heard if first, I thought along the same lines as you and kept saying to myself ' you can never get cassettes to sound like that'! It reminded me of some tricks that Japanese manufacturers used to get ultra-wide responses some reel-to-reels. The 680ZX and its younger cousins, however, are for real. They do down that low and give cassettes a lot more dynamics then you thought was possible without help from Dolby or DBX. Rgds, Bala Roland wrote: I keep hearing a LOT about the 670 and 680 series. Is the bass response relatively flat down to ???hz or is it an artificially created sweetspot? I've listened to those cheap multi-unit stereo systems that basically go boom, boom, boom and I know I have some friends that mistake that as bass response.

I was trying desperately to remember what I had seen (I came across a ZXE in Seoul a few years ago). I notice a mistake on my original letter: I said the machine looked similar to a ZXE, minus some of the lights; of course, I meant similar to a 700ZXL! I'd be interested to know, since it seems they were manufactured a little after the ZXLs, if the ZXEs contained any electronic 'improvements' to the slightly earlier ZXLs. Take the 680 series, for example. Although the 680ZX is regarded as a wonderful machine with a terrific, deep bass, the slightly later 682ZX is said to have superior auto-calibration, yet not the same powerful bass of the 680ZX.

The wide dynamic range of the 700ZXE is astonishing! to say the least!

The 700ZXL however does not contain a processor for the auto-cal. It does contain one for the RAMM system however. The auto-cal system of the 700ZXL centers more around it's MSM series memory chips which have a pass-thru mode. The system thus uses a simplified logic by taking the tape type and choosing the optimum Bias and Level and performs a linearization at a single frequency. This method, greatly simplifies matters and hence Nakamichi got away from using a processor. Thus, the 700ZXL has a simpler EQ circuit as well, unlike the 1000ZXL which has a dedicated record EQ board and has a more elaborate bias feature. One other feature that the 700ZXL didn't have that the 100ZXL does, is parametric erasure. The erase and record bias use two seperate osciallators running at different frequencies. The price different does not tell you, but there is a lot more going under the hood between these two cousins! Rgds Kevin Fetner wrote: This place has been sort of my Bible for cassette deck info.

Very similar features and both say micro-possessors used (Bala says no on this). In their site, they don't say the ZXE has full A.B.L.E., but does have auto bias, auto level. Also, it doesn't say that the ZXE has memory storage for the various tapes used like the ZXL. It's a bit confusing, so I'd certainly defect to the knowledgeable opinions here. $600 difference, so they trimmed something out I suspect.

Vineyards have better quality wines some years over others. Grapes are a result of growth changes that are dependent on water, soil conditions. These specialists make good/bad timing decisions having a direct effect on flavor quality and hence an agreeable or disagreeable taste palate. Did the engineering departments, of say Aiwa and Nakamichi, whose evolution in ideology, or component selection decisions, produce a superior series, or an inferior design between the various Aiwas and Nakamichi models? If we start in the 70', then into the 80's and finally 90's what patterns emerge? What design or purchasing depts decisions, (such asopting for cheaper components and less complex designs) had a direct effect in sound variations, say (if one excludes the orange caps) between say the Tri tracers/ZXL and the RX/Dragon series? Is there a pattern? Is a servo actuator more reliable than a motor driven one? In as much as the early AD6900/II had outstanding build quality, then if one goes by Bala's statement about the engineers suggestion to forgo the F990 and stay with the Excelia/XK series. Any thoughts?? -------------- Original message from Steve Ember : -------------- Hello, all, and best wishes for the New Year! One never knows what stimulating topics might turn up in this forum, and anything stimulating when you gotta work on New Year's Day with a sleep deficit resulting from the night before is to be applauded (just not too loudly, please) ;-) I've been following some of the comments relating to comparisons of characteristic sound of our beloved Naks, sometimes as related to high end decks of other manufacturers. In reading ddino77's post today, I can see I'll soon be "resurrecting" a favorite deck of mine for some comparison-listening... I, too, own an Aiwa 6900 Mk.II, as well as two of its predecessors, the 6900. They were all purchased new in the '70s, well before I got into Nakamichis. At the risk of veering too much OT in praising a non-Nak, I'd simply say that, at the time, I could not afford the high end Naks of the 1000 and 700 series, but was mightily impressed by the solid construction of those top-of-the-line Aiwas -- and, boy, were they h-e-a-v-y -- the very responsive transports, which provided audible fast search directly from Play, the double needle meters, which allowed one to view simultaneously, or separately, both VU and Peak characteristics of the music being recorded, the very capable F.R.T.S. tape tuning system, which allowed front panel optimizing of not only bias but level, to minimize the dreaded Dolby-B mistracking. It was also reasonably easy to get at the PB head azimuth while in Play to optimize dull-sounding tapes made on other people's machines. Oh, yes, they were indeed handsome brutes with their brushed silver front panels, and ergonomically very impressive as well. I used my 6900s not only for serious music recording, but also for production purposes in my studio -- hence the admiration of the audible fast cueing, super-fast winding, and the other features noted above, as well as their super-reliability. For a few years, I had two of these machines under daily timer control to record air-checks of my radio programs. And, yes, they did absolutely superbly with Type I C-120s. Please forgive the sentimental digression. The reason I found dino's post so stimulating is that, while I found my 6900's so satisfying in heavy usage, I guess I did not realize their sound could be described as smooth and tube-like in sound quality. My admiration for their sound was that, after doing the (manual) F.R.T.S. set-up, I could flip back and forth between input and tape while recording and hear NO appreciable differences between them. CD's, of course -- dare I say good CDs? -- did push the Aiwa's envelope, but only in S/N against very low level passages, as the 6900's had only Dolby-B NR. Even so, taking advantage of those fast responding Peak meters allowed the user to get the most S/N from any tape, up to the saturation point. And even there, as we analog folks know, the tape handled it very gracefully -- i.e., musically), kinda like, err, TUBES (Valves for you lot across the Pond). I can still listen to any number of cassettes, whether from vinyl or CD, made on those 6900s and smile. Broadly! Being a professional user of the cassette medium, still into the 90's, I could not resist the appeal of the Nakamichi CR-7A, in terms of nailing azimuth -- just so much more elegant to switch to mono and turn the 7's azi adjust knob till the high sounded identical, than sticking tiny screwdrivers into the 6900's. But even that did not diminish my love for using my three 6900 "tanks." So, the four decks existed side by side. A few years ago, the lust for Nakamichis I couldn't afford when new, especially the UDAR machines like the RX-505 and 202, led me to start purchasing some of these, as well as other Naks. There being only so much space in my studio, certain decks had to sit "in reserve" as the fleet grew. Thus, my trusty 6900II, after a thorough overhaul and tuning a few years ago, never got plugged back in. Yep, I've looked at it longingly, and as to the last repair's warranty...well, fugettabout it if anything escaped attention...or if the new rubber installed went south from disuse ;-) Well, I never said I was "smart." Just passionate about this lovely gear... While I'd always considered the 6900 and the 6900 II, the high-water mark of Aiwa, I later learned of the XK-S9000, which truly was their last fine deck. It even provided, in addition to Dolby-B and -C, Dolby's high-water mark in consumer NR, Dolby-S. Guess it was also their valedictory, as it came out when cassette was, in the eyes of most, passé. It was just as handsome as the 6900s, only in perhaps a more upscale way, with champagne colored front panel and high-gloss rosewood side panels. I also knew, from its published weight that there was a pretty good chance of its being as well-built as the 6900's. Well I found one in mint condition from a very meticulous seller on ebay, and it's doing sterling service as (currently) one of my most used decks. But -- finally, I hear y'all saying -- back to Nakamichi! As I stated in a previous post, the itch to have one Golden Age Nakamichi finally had to be scratched. And that led me to buy my 700 ZXE from that same meticulous seller. Due to an impossible schedule over the last several months, I felt it wiser to keep the 700 packed up until I could relax and really get to know it. So, thanks Dino! I now have some stimuating reasons in this New Year to unpack the 700 ZXE (guessing it's close enough in vintage to the earlier 700's that "tube-ish" might still apply!), and to pull the 6900 II off the reserves, and set them both up alongside the XK-S9000 for some comparison listening. Hey, ain't this hobby FUN? Enjoy the music, all, and Happy New Year!

Where as the XK-S9000 was a product of the digital revolution and sits side by side with the Dragon for CD resolution (reproduction) purposes. -------------- Original message from Mark Exstedt : -------------- Thanks for the info Bala. I also have an Aiwa AD-F990 cassette deck. It's mint. After I purchased it, I got a belt replacement / calibration / head alignment / speed control adjustment / tune up. I obtained it from the original owner along with the owners manual and the receipt. I believe it was $579 what he paid for it. The guy never used it. It even had the plastic wrapping on the cover! I still have not yet used it for recording purposes, but your input got me excited. I value it at $300, but am presently uncertain if I will sell it. Date: Tue, 30 Dec 2008 20:51:26 -0800 From: bg3009 at yahoo.com Subject: Re: [naktalk] Re:1000ZXL versus 700ZXL To: naktalk at naks.com Hi Kevin, It is a technical marvel, and looking at the circuit, you would never guess that it actually works! Comparing it to later decks like the CR7 which has a similar auto-cal system, the 700ZXL does seem aged, clunky and complicated. But it still works! The Aiwa F series decks are seriously the decks to go for as far as Aiwa is concerned. Many know the Excelia and the XK-9000S better, but again this is more of a marketing thing. The F series decks pack a long list of features such as auto-calibration, flourescent meters, real-time/linear counter, auto- head demagnetizing etc, depending on the model. A complete list of features can be found on the vintage cassette deck website. Sound-wise, it has a very warm, pleasing sound with good soundstaging. The bass is not very low, nor does it posses extended highs. But this is a cassette deck that you can listen to for very long hours without tiring one's ears. I have a AD-F990 which has been in my house since '83. Tapes made on this deck 20 years ago, out-perform CDs today! Build quality is, sadly, downright cheesy. Drugstore quality? Right! The chassis is pressed sheet metal and the wiring is a tangled rat's nest. The transport mechanism is incredibly complex and fragile. It is becoming more difficult to maintain these decks due to the fragility and lack of parts. The AD-F, and earlier AD series decks however, have a charm of their own.

The 1000ZXL and 700ZXL are quite different although they seem to spec out almost the same. The 700ZXL shares the same playback/Dolby board and a similar RAMM system with the 1000ZXL. Much of the transport related logic and auto-azimuth circuits are also similar though the circuity has been rather crammed into a smaller boards. One of the key difference is that that the ABLE system is very different from the the 1000ZXL. It isn't controlled by a micro-processor (although all available literature suggests that it does) but uses sequential logic made up of multiple logic circuits. The good news is that this is fixable as parts are plentiful. The bad news is that it can be a pain to troubleshoot! The auto-calibration uses only two frequencies 400Hz for level and 15kHz for the bias adjustment. A third frequency (7kHz) is used to linearize the EQ. This differs greatly from the 1000ZXL's ABLE computer which does use a micro-processor, and uses 4 different frequencies for a true calibration irregardless of tape type inserted. The 1000ZXL, in my opinion, is a more through system that features a micro-processor. The processor, is a 4-bit PMOS model that has seen widespread use in some of the best cassette decks made during the late 70s and early 80s. This include the Aiwa F series (990, 880, 660 etc) and Aiwa 6700, 6900 and 6900II. Sound wise, these two decks differ quite a bit. The 1000ZXL has a more bigger sound, with deep and wide soundstage. The bass is more deeper, perhaps thanks to its more generous power supplies. The 700ZXL sounds slightly closed in, and the bass is not as refined as it's bigger cousin. It does however have equally sweet highs and capable of bringing out the best out of pre-recorded tapes if azimuth is in sync, as with the 1000ZXL. With the amount of engineering differences, Nakamichi seems to have cut lots of cost, though this also results in differences in sound quality. The 700ZXL is however very close up there to the 1000ZXL. They however, don't seem to be build for longevity and chassis stiffness leaves much to be desired. One thing I would love is to have LP's LED upgrade kit for the control compartment illumination!

I also have an Aiwa AD-F990 cassette deck. It's mint. After I purchased it, I got a belt replacement / calibration / head alignment / speed control adjustment / tune up.I obtained it from the original owner along with the owners manual and the receipt. I believe it was $579 what he paid for it.The guy never used it. It even had the plastic wrapping on the cover! I still have not yet used it for recording purposes, but your input got me excited. I value it at $300, but am presently uncertainif I will sell it.

Comparing it to later decks like the CR7 which has a similar auto-cal system, the 700ZXL does seem aged, clunky and complicated. But it still works! The Aiwa F series decks are seriously the decks to go for as far as Aiwa is concerned. Many know the Excelia and the XK-9000S better, but again this is more of a marketing thing. The F series decks pack a long list of features such as auto-calibration, flourescent meters, real-time/linear counter, auto- head demagnetizing etc, depending on the model. A complete list of features can be found on the vintage cassette deck website. Sound-wise, it has a very warm, pleasing sound with good soundstaging. The bass is not very low, nor does it posses extended highs. But this is a cassette deck that you can listen to for very long hours without tiring one's ears. I have a AD-F990 which has been in my house since '83. Tapes made on this deck 20 years ago, out-perform CDs today! Build quality is, sadly, downright cheesy. Drugstore quality? Right! The chassis is pressed sheet metal and the wiring is a tangled rat's nest. The transport mechanism is incredibly complex and fragile. It is becoming more difficult to maintain these decks due to the fragility and lack of parts. The AD-F, and earlier AD series decks however, have a charm of their own.

And yeah, I thought the A.B.L.E. system was controlled by a micro-processor...hmmmmmm. Funny you should mention the Aiwa F series-that's the cassette 'bootleggers' deck (I mentioned in another post) that I'm waiting almost two yrs for.;-) It has some novel features, but build quality is 'drugstore brand'.

The 1000ZXL and 700ZXL are quite different although they seem to spec out almost the same. The 700ZXL shares the same playback/Dolby board and a similar RAMM system with the 1000ZXL. Much of the transport related logic and auto-azimuth circuits are also similar though the circuity has been rather crammed into a smaller boards. One of the key difference is that that the ABLE system is very different from the the 1000ZXL. It isn't controlled by a micro-processor (although all available literature suggests that it does) but uses sequential logic made up of multiple logic circuits. The good news is that this is fixable as parts are plentiful. The bad news is that it can be a pain to troubleshoot! The auto-calibration uses only two frequencies 400Hz for level and 15kHz for the bias adjustment. A third frequency (7kHz) is used to linearize the EQ. This differs greatly from the 1000ZXL's ABLE computer which does use a micro-processor, and uses 4 different frequencies for a true calibration irregardless of tape type inserted. The 1000ZXL, in my opinion, is a more through system that features a micro-processor. The processor, is a 4-bit PMOS model that has seen widespread use in some of the best cassette decks made during the late 70s and early 80s. This include the Aiwa F series (990, 880, 660 etc) and Aiwa 6700, 6900 and 6900II. Sound wise, these two decks differ quite a bit. The 1000ZXL has a more bigger sound, with deep and wide soundstage. The bass is more deeper, perhaps thanks to its more generous power supplies. The 700ZXL sounds slightly closed in, and the bass is not as refined as it's bigger cousin. It does however have equally sweet highs and capable of bringing out the best out of pre-recorded tapes if azimuth is in sync, as with the 1000ZXL. With the amount of engineering differences, Nakamichi seems to have cut lots of cost, though this also results in differences in sound quality. The 700ZXL is however very close up there to the 1000ZXL. They however, don't seem to be build for longevity and chassis stiffness leaves much to be desired. One thing I would love is to have LP's LED upgrade kit for the control compartment illumination!

If this does not work, try doing it on another quality tape. If that fails, your bias oscillator capacitors might be fried on the right channel and need replacement! Good Luck.

The silky smooth feel comes from a fairly heavy lubricant between the shaft and the inner surface of the bushing. Most controls need but a small (very small) quantity of the cleaner on the track, nowhere else. Rebuilding a control is tedious -- I have never done it on a Nak, where fairly high quality control pots are used. I have done it on test instruments, after a very long period of non used caused the control to freeze. Once I take the pot apart, I clean it very thoroughly, then lubricate the bushing with grease, spread a drop of 'Contact Cleaner with Lubricant' on the track, and re-assemble the pot. I find the it then feels exactly like a brand new control (and lasts as long. too). -- Ron Gaby wrote: > Hello everyone, > > > I have a dilemma with the control cleaners.

Leave the front panel bias knobs in the centre, and use the individual screwdriver bias adjustments below the knobs. For Record Level, you can use the front panel knobs, but bear in mind that there are also Record Level preset pots inside on Cal B PCB. You might find these useful if you can't achieve good Record Level adjustment with the front panel knobs, or if you end up with large differences in the front panel Record Level knob settings. There is only one bias oscillator for L and R channels, and the 600 and 600 II didn't have a capacitor problem in their bias oscillators - this problem started with later Nakamichi models. It's not likely that your adjustment problems are due to defective caps as suggested. It's also possible (but less likely) that you have a worn R/P head - this could also account for a loss of level at 400Hz, but would be unlikely to give you the 10KHz results you are getting. The 600 and 600 II can be adjusted successfully on tapes such as TDK SA in the SX position, but I think they had trouble with higher bias tapes such as TDK SAX. (I haven't fiddled with a 600 for a decade or so, so please forgive me if my memory is defective here.) Good luck John Gipps Message: 2 Date: Sat, 3 Jan 2009 03:43:39 -0600 From: "Robert L.

If this does not work, try doing it on another quality tape. If that fails, your bias oscillator capacitors might be fried on the right channel and need replacement! Good Luck.

Message-ID: Happy New Year to everybody on the forum! Testing my NAKs first time after I got each one and using brand-new 400Hz 200nWb/m test tape I notice difference in Reference Fluxivity of test tapes used to set the reproducer gain so that the VU-meter reads “0dB” which corresponds to particular Output Level of each model (600 mV for N-480, 1000mV for N-582, N-680ZX, N-1000ZXL and Dragon, 500 mV for CR-4). Then I notice that earlier models like 480s, 582s, 680s, 1000ZXLs and early runs of Dragon required DA09005A 400Hz Level Tape with 200nWb/m Reference Fluxivity (all of them showed “0dB”with 200nWb/m Test Tape). CR-4s and late Dragons required DA09005B 400Hz Level Tape and showed about 2dB above “0dB”. The question is: does DA09005B tape have 160nWb/m Reference Fluxivity at 400Hz ? I’ve been told it does. 20*log(200/160)=1.938dB Thanks in advance.

Happy New Year to everybody on the forum! Testing my NAKs first time after I got each one and using brand-new 400Hz 200nWb/m test tape I notice difference in Reference Fluxivity of test tapes used to set the reproducer gain so that the VU-meter reads “0dB” which corresponds to particular Output Level of each model (600 mV for N-480, 1000mV for N-582, N-680ZX, N-1000ZXL and Dragon, 500 mV for CR-4). Then I notice that earlier models like 480s, 582s, 680s, 1000ZXLs and early runs of Dragon required DA09005A 400Hz Level Tape with 200nWb/m Reference Fluxivity (all of them showed “0dB”with 200nWb/m Test Tape). CR-4s and late Dragons required DA09005B 400Hz Level Tape and showed about 2dB above “0dB”. The question is: does DA09005B tape have 160nWb/m Reference Fluxivity at 400Hz ? I’ve been told it does. 20*log(200/160)=1.938dB Thanks in advance.

There's a similar parallel wit the DBX stuff where 122/222 could only record OR play. You needed a second unit or 124/224 to be able to properly monitor. Kenwood was one of the first to promote the phrase "Double Dolby" with the KX-1030 which had three heads and could monitor off tape with Dolby decoding as a result of having two Dolby boards. Nak comes in with the intriguing (if not downright frustrating) 481/581which were three head decks which did not have the associated simultaneous playback circuitry to allow off tape monitoring. While this allowed you to reap the benefit of the 3 head design while saving a few bucks, calibration is ultimately just as cumbersome as on a 600 (rec/rew/play/repeat/repeat/repeat///).

Most (but not all) 3 head decks contain two separate Dolby circuits. one dedicated to coding, the other to decoding. Marketing blurbs sometimes refer to this as 'double Dolby circuitry'. This allows monitoring off the tape during recording. Because it is more expensive than a single code/decode circuit, some low cost 3 head decks do not offer dual Dolby circuitry. They still offer other advantages of 3 heads decks. -- Ron Kevin Fetner wrote: > Ram, > Is this the same as 'double ended' NR...where you must > playback using the same NR system that you recorded with? > Are you saying that historically, there were cheaper, two head > decks that only played back Dolby encoded tapes, but did not > record with them? > > Kevin > > > > > Kevin, > > Double NR means its got two dolby circuitries, one for playback( decoder circuit) and the other for the recording circuit( decoder) > > Double dolby circuits are usually associated with three head decks. > > Regards, > Ram > > --- On Sun, 1/4/09, Kevin Fetner > wrote: > From: Kevin Fetner > > Subject: [naktalk] Promo > literature > To: naktalk at naks.com > Date: Sunday, January 4, 2009, 12:13 AM > > > > > All, > Other than ebay, where would be > a good place to hunt for original Nak sales/promotional literature > for the various models?

It is clearly a mechanical problem as, if I open the machine and help it by gently rotating the heavy black rotor of the direct drive motor with the end of a finger, then it starts. Thus, it seems that it needs some lubrification or something like that, do you have an idea of what should be done? or what is that due to? do these rotors usually need lubrification? can lubrification can be performed from the front without removing any part but the black front plate(that hides the idler tire)? If I have tried to extract the mechanism part of the deck to chech the rotors of both cabestans but this is not obvious for me. Could you give me some advice to do so successfully? I have read that the mechanism part on CR7 was extracted by the front ? Is it the same for teh BX300? Thank's for your answer.

Comparing it to later decks like the CR7 which has a similar auto-cal system, the 700ZXL does seem aged, clunky and complicated. But it still works! The Aiwa F series decks are seriously the decks to go for as far as Aiwa is concerned. Many know the Excelia and the XK-9000S better, but again this is more of a marketing thing. The F series decks pack a long list of features such as auto-calibration, flourescent meters, real-time/linear counter, auto- head demagnetizing etc, depending on the model. A complete list of features can be found on the vintage cassette deck website. Sound-wise, it has a very warm, pleasing sound with good soundstaging. The bass is not very low, nor does it posses extended highs. But this is a cassette deck that you can listen to for very long hours without tiring one's ears. I have a AD-F990 which has been in my house since '83. Tapes made on this deck 20 years ago, out-perform CDs today! Build quality is, sadly, downright cheesy. Drugstore quality? Right! The chassis is pressed sheet metal and the wiring is a tangled rat's nest. The transport mechanism is incredibly complex and fragile. It is becoming more difficult to maintain these decks due to the fragility and lack of parts. The AD-F, and earlier AD series decks however, have a charm of their own.

The 1000ZXL and 700ZXL are quite different although they seem to spec out almost the same. The 700ZXL shares the same playback/Dolby board and a similar RAMM system with the 1000ZXL. Much of the transport related logic and auto-azimuth circuits are also similar though the circuity has been rather crammed into a smaller boards. One of the key difference is that that the ABLE system is very different from the the 1000ZXL. It isn't controlled by a micro-processor (although all available literature suggests that it does) but uses sequential logic made up of multiple logic circuits. The good news is that this is fixable as parts are plentiful. The bad news is that it can be a pain to troubleshoot! The auto-calibration uses only two frequencies 400Hz for level and 15kHz for the bias adjustment. A third frequency (7kHz) is used to linearize the EQ. This differs greatly from the 1000ZXL's ABLE computer which does use a micro-processor, and uses 4 different frequencies for a true calibration irregardless of tape type inserted. The 1000ZXL, in my opinion, is a more through system that features a micro-processor. The processor, is a 4-bit PMOS model that has seen widespread use in some of the best cassette decks made during the late 70s and early 80s. This include the Aiwa F series (990, 880, 660 etc) and Aiwa 6700, 6900 and 6900II. Sound wise, these two decks differ quite a bit. The 1000ZXL has a more bigger sound, with deep and wide soundstage. The bass is more deeper, perhaps thanks to its more generous power supplies. The 700ZXL sounds slightly closed in, and the bass is not as refined as it's bigger cousin. It does however have equally sweet highs and capable of bringing out the best out of pre-recorded tapes if azimuth is in sync, as with the 1000ZXL. With the amount of engineering differences, Nakamichi seems to have cut lots of cost, though this also results in differences in sound quality. The 700ZXL is however very close up there to the 1000ZXL. They however, don't seem to be build for longevity and chassis stiffness leaves much to be desired. One thing I would love is to have LP's LED upgrade kit for the control compartment illumination!

To make a simple gauge by hand I would use a piece of 18 or 20 gauge aluminium carefully marked out and equally carefully filed by hand, checked with vernier calipers until correct width is achieved. An improved version of this device would have an attachment that fitted over the erase head as well as the record/playback head, aligning all heads with the pinch roller guides.

There's a  similar parallel wit the DBX stuff where 122/222 could only record OR  play. You needed a second unit or 124/224 to be able to properly  monitor. Kenwood was one of the first to promote the phrase "Double  Dolby" with the KX-1030 which had three heads and could monitor off  tape with Dolby decoding as a result of having two Dolby boards. Nak comes in with the intriguing (if not downright frustrating)  481/581which were three head decks which did not have the associated  simultaneous playback circuitry to allow off tape monitoring. While  this allowed you to reap the benefit of the 3 head design while saving  a few bucks, calibration is ultimately just as cumbersome as on a 600  (rec/rew/play/repeat/repeat/repeat///).

Actually, the problem could be electrical, such as failure of the drive circuitry (most likely, the driver IC). Check the voltage actually applied to the motor (should be 11.7V). If lower, check the drop across R608 (5.6 Ohm). Should be 0.3V or so. Also, check the +12V supply line. > Thus, it seems that it needs some lubrification or something like > that, do you have an idea of what should be done? Usually, lack of lubrication will cause increased W/F and not freezing. However, do try to lubricate and see if it helps: The easy way to lubricate capstan bearings: stand the deck on its rear panel, raise the washer off each capstan (no need to remove, just lift them) and apply light machine oil to the bearing of each capstan. Pull each capstan up a few times, to let the oil seep in, Let stand for a few hours, to let the sintered bronze bearings absorb some of the oil. Then, lower the washers and thoroughly clean the capstans. It may be that the above doesn't fully lubricate the full depth of the bearing. If so, the DD motor has to be taken apart, the capstans removed and the bearing cleaned and lubricated. (If you have never done this or are not technically inclined, you may wish to have it done professionally.) At the same time, a tiny blob of grease should be applied to the backing plate behind the supply (belt driven) capstan.

It's like light finger tapping two times a second in playback mode, and fast tapping in FF/RW mod. However, I've noticed a similar repeating sound coming from the Dragon when listening closely to a video found on the web: http://www.metacafe.com/watch/506469// Maybe, I'm being too sensitive or overly suspicious of the mechanical noise.

Again, just my subjective observation. Take it for what its worth.

It is clearly a mechanical problem as, if I open the machine and help it by gently rotating the heavy black rotor of the direct drive motor with the end of a finger, then it starts. Thus, it seems that it needs some lubrification or something like that, do you have an idea of what should be done? or what is that due to? do these rotors usually need lubrification? can lubrification can be performed from the front without removing any part but the black front plate(that hides the idler tire)? If I have tried to extract the mechanism part of the deck to chech the rotors of both cabestans but this is not obvious for me. Could you give me some advice to do so successfully? I have read that the mechanism part on CR7 was extracted by the front ? Is it the same for teh BX300? Thank's for your answer. __________________________________________________________________________ I had the same problem with my BX300E *after* I lubricated my capstans. I did the lubrication as part of preventive maintenance, not because the deck was underperforming in any way. My mistake, looking back, was to use oil that was slightly too heavy. Once my deck has warmed up for 10-15 minutes by just standing (or by winding a tape to warm up faster) the capstans rotate fine and everything is OK. In the colder weather this takes longer which makes me think the viscosity of the oil I used has to decrease slightly before the resistance on the capstan shafts decreases. Of course, this could be masking a deeper problem but if a short warm-up can get the Nak playing I'm happy. I don't know exactly what type of oil is best - I'm sure it has been discussed before. I used the light oil that came with my beard trimmer (you can all stop laughing now...). Good luck with getting the BX300E working nicely.

The info on the possibility of different reference level tapes by Nakamichi made me curious, though. Over the last few weeks, I've gotten pretty adept at calibrating decks as I have been practicing with lesser makes like Tascam, Sony, Harman Kardon, etc. I can get them pretty much spot on with my true rms Fluke 289 and oscilloscope for azimuth. I've set the azimuth of all my non-Nak decks to the Dragon record head as most of my tapes are made with the Dragon. Music needing pitch correction from the source, I use the MR-1 and then re-digitize at correct pitch and then finally burn my own CDs. (This works for the most part but does not take into consideration some orchestras and even musicians tune to a different reference.) The tapes made on the Dragon actually sounds pretty good on the lesser decks in spite of the difference in IEC EQ standard. (and the different reference levels used by them.)

Happy New Year to everybody on the forum! Testing my NAKs first time after I got each one and using brand-new 400Hz 200nWb/m test tape I notice difference in Reference Fluxivity of test tapes used to set the reproducer gain so that the VU-meter reads “0dB” which corresponds to particular Output Level of each model (600 mV for N-480, 1000mV for N-582, N-680ZX, N-1000ZXL and Dragon, 500 mV for CR-4). Then I notice that earlier models like 480s, 582s, 680s, 1000ZXLs and early runs of Dragon required DA09005A 400Hz Level Tape with 200nWb/m Reference Fluxivity (all of them showed “0dB”with 200nWb/m Test Tape). CR-4s and late Dragons required DA09005B 400Hz Level Tape and showed about 2dB above “0dB”. The question is: does DA09005B tape have 160nWb/m Reference Fluxivity at 400Hz ? I’ve been told it does. 20*log(200/160)=1.938dB Thanks in advance.

Cheaper three-heads have only one NR circuit that works like two-heads do, so when you're recording with Dolby, the monitor output is playing back the tape without Dolby decoding as the NR circuit is already in use for recording. -------------- next part -------------- An HTML attachment was scrubbed...

In addition, you will have to add a 12V/40mA (size T1) lamp behind the plate -- if memory serves, the thin sheet metal lamp holder is already there. Finally, you will have to add a 12V line to the transport (the PCB has a free copper island that can be used to connect this line to one of the lamp wires. the other goes to ground). Is it worth the bother? For most people, the answer is no.

That does mean that the dolby only work for either play or record, but not both at the same time. It is thus less expensive and I would say gets my vote for classic on a budget. The playback and record are just as good as the 670zx except that you can't compare directly source/playback when setting up recording. It and the BX-300 are my favorite less expensive decks.

It is clearly a mechanical problem as, if I open the machine and help it by gently rotating the heavy black rotor of the direct drive motor with the end of a finger, then it starts. Thus, it seems that it needs some lubrification or something like that, do you have an idea of what should be done? or what is that due to? do these rotors usually need lubrification? can lubrification can be performed from the front without removing any part but the black front plate(that hides the idler tire)?   If I have tried to extract the mechanism part of the deck to chech the rotors of both cabestans but this is not obvious for me. Could you give me some advice to do so successfully? I have read that the mechanism part on CR7 was extracted by the front ? Is it the same for teh BX300?   Thank's for your answer.   __________________________________________________________________________   I had the same problem with my BX300E *after* I lubricated my capstans.  I did the lubrication as part of preventive maintenance, not because the deck was underperforming in any way.   My mistake, looking back, was to use oil that was slightly too heavy.  Once my deck has warmed up for 10-15 minutes by just standing (or by winding a tape to warm up faster) the capstans rotate fine and everything is OK.  In the colder weather this takes longer which makes me think the viscosity of the oil I used has to decrease slightly before the resistance on the capstan shafts decreases.   Of course, this could be masking a deeper problem but if a short warm-up can get the Nak playing I'm happy.   I don't know exactly what type of oil is best - I'm sure it has been discussed before.  I used the light oil that came with my beard trimmer (you can all stop laughing now...).   Good luck with getting the BX300E working nicely.   Chris========---------------------------------------------------------========= Register your Nak today! http://www.naks.com/register ========---------------------------------------------------------========= Naktalk at naks.com mailinglist Maintain your account here: http://www.naks.com/mailman/listinfo/naktalk ========---------------------------------------------------------========= -------------- next part -------------- An HTML attachment was scrubbed...

The gauge needs to be made to find tolerance +/- 0.1mm or better, I machined mine on a milling machine (from "Lexan") but it can be made by hand to the same tolerance if you are skilled and careful. The basic dimensions are 50mm long, the body 4mm wide and the erase cover section needs to be 6mm inside to neatly sit over the erase head, the thickness of the tool is not important and can be made from sheet metal.

Unfortunately, it wasn't another Nak, but it is a visually impressive deck,...........and it sounds good too. Got a non-working Marantz sd9000 Compudeck. (It's working now) Was their top-of-the-line back in the early 80's. It is a two speed, three head, dolby B deck. By the way, with reference to another thread here, it mentions in the owner's manual that it has separate record and playbeck dolby units, so you can listen to your tape as recording with dolby on. These decks have a known problem with the tape movement sensors. That is the problem I fixed by disassembing the tape mechanism, and replacing the sensors. While the mech was disassembled, I went ahead and replaced 3 belts and 3 idlers as well. Seems to work as new. Anyway, thanks for letting me share. I was very pleased with the repair and the operation of this deck Thanks. Bobby -------------- next part -------------- An HTML attachment was scrubbed...

At least the deck would offer 'something'. Kevin No. Most such decks simply do not monitor during recording. Monitoring with no Dolby decoding would defeat the purpose, since the monitored sound would not represent the recording. I am not sure why they avoid monitoring even when Dolby NR is switched off, as the added cost would then be small. -- Ron -------------- next part -------------- An HTML attachment was scrubbed...

In the coming years, when spares have truly waned, this may be the path forward to keeping our Naks running. This seems very similar to the ceramic stators in the capstan motors used in Tandberg 10X series reel to reel decks. With good lubrication on the sleeve bearings, it would probably take a considerably amount of time and load before the capstan shafts wear. The key though, is good lubrication.

The diagrams omit the power supply, erase head and bias/erase oscillator for clarity. First, consider the general differences of 2-head (Nakamichi 350, 500, 250, 600, 600-II) and 3-head (Nakamichi 700, 1000) decks. A 3-head deck allows the operator to switch between the input and playback signals during recording. In effect, a 3-head deck is two separate machines in one: a recorder and a player sharing a common tape drive, power supply and cabinet. There are separate electronic circuits for its Playback amplifier, Dolby Decoder, Recording Amplifier and the Dolby Decoder. Of course, it also has a separate head for recording and for playback. A 3-head deck features a straightforward INPUT/PLAY MONITOR MODE switch or relay that lets the operator select the signal from the input amp or the playback chain. Manufacturers have adopted different names for the presence of the separate Dolby Encoder and Decoder circuits: Double Dolby, Simultaneous Encode/Decode, Dual Dolby, or similar terminology. -------------- next part -------------- A non-text attachment was scrubbed... Name: 3hd.jpg Type: image/jpeg Size: 22701 bytes Desc: not available URL: -------------- next part -------------- A 2-head deck doesn't allow the operator to switch between the input and playback signals during recording. A 2-head deck has an elaborate RECORD/PLAY MODE switch or relay that, in essence, re-wires the circuitry of the deck for recording or for playback and switches the direction of the signal flow to or fro the REC/PLAY head. Much of the circuitry is in common for both record and play modes, and the Dolby circuit shares much of the same circuitry. Tracing the REC/PB switch in the schematic and how it affects signal flow can turn your brain into mush. -------------- next part -------------- A non-text attachment was scrubbed...

Name: 2hdplayback.jpg Type: image/jpeg Size: 31762 bytes Desc: not available URL: -------------- next part -------------- During PLAYback mode, the operator hears the input signal before it reaches the Dolby encoder. Some 3-head machines, like the Bang & Olufsen Beocord decks, act like 2-head machines. They automatically select REC or PLAY mode depending on whether the PLAY or REC buttons are selected. Although they do have three heads, during RECord they monitor like a 2-head deck. During playback, though, you are listening to the dedicated PLAYback head. But like a 2-head deck, these oddball machines during RECord mode use their REC/PB switch to rewire the deck so the operator hears the input signal before it reaches the Dolby encoder. The Dolby circuit also behaves like a 2-head. By the way, 2-head decks often suffer less Dolby mistracking because of the fact that much of the Dolby circuitry is in common with both PLAy and REC modes. Some early-production studio Dolby A units switch signal flows like a 2-head consumer deck, and do not offer simultaneous encode/decode. This requires retrofitting the 3-head studio reel-to-reels with unusual signal flow switching. I went though that with the Dolby M8 and M16 Type A noise reductions I used with my Scully and Studer reel- to-reels. -- Kermit Gray notarbene at kvglabs.com KVG Laboratories Equipment to Make Your Music Better 16371 Lake Point Drive Bonner Springs, KS 66012 USA Telephone: 913-422-0957 Skype ID: triodelicacy From kjlee at people.net.au Fri Jan 9 03:18:32 2009 From: kjlee at people.net.au (ken lee) Date: Fri, 09 Jan 2009 13:18:32 +1100 Subject: [naktalk] Modified zx9 motor In-Reply-To: <10679306.1231428537706.JavaMail.root@elwamui-mouette.atl.sa.earthlink.net> References: <10679306.1231428537706.JavaMail.root@elwamui-mouette.atl.sa.earthlink.net> Message-ID: <4966B3F8.8090504@people.net.au> Tom Brucker wrote: > > Me too.

This is a very early 5 inch floppy drive, it has no segment feel, the magnet does not enclose the drive coils, they are underneath the motor PC board, everything worked with this motor. I am considering doing this mod, to another nak, it will not look the same as this, I would like to do it with a 3 inch drive. I collected my 5 and 3 inch floppy drives from a university i was working at, they are often a good source of old computer bits, just ask around, there are thousands of old floppy drives gathering dust out there somewhere.

Check the emitter of Q420 for negative 12v. If that is present, suspect Q420 as an open transistor. These two transistors swing positive or negative to drive the reel motor either in forward or reverse. Good luck.

Actually, this morning, the BX300 began to slow down while playing a cassette and then I though "Yes, Ron was rigth, the problem is more likely to be electrical". I went to the shop to buy an electrical controller and checked the various points about which you adviced me. 1. I check on the PCB board itself: the "orange" spot and the "black" one (both are the more possible on the left and on the lowest position when you look at the board from behind (sorry for my poor english): I measured 11.04-11.05 V while capstans rotating without a cassette inside to drive. Then I put a cassette in, and the voltage dropped down to 9.94 V ! 2. Then, I checked the 12 V on the right on R608 (always considering you are looking inside from behind: by the way R608 is recognisable because it is not soldered stuck on the main board but about 1 cm away from it because of possible heating?:(thank's Claude for localizing R608): result : 12.00V ! on the left of R608: 11.04 V (after having stopped cassette) So, Ron, if I well understand, does that mean that R608 has to be changed ?

I kinda doubt it's bad, but measure anyway. .If *not *within 5.6 Ohm ±5%, replace. Otherwise, R608 is good and your measurements indicate that the motor current draw is too high. Possible mechanical causes: bearings are not correctly lubricated. (try to remove the belt and check to see whether the motor is still sluggish to start. If not, the supply bearing is suspect). Possible electrical causes: a shorted turn, a bad driver IC, bad hall effect sensor and quite a few others. If you have a 'scope, start by looking at the drive out of IC101, pin pairs 8,9 and 11,12. If not, you can take a chance and just replace the IC (M51721L). It's not that expensive, if you can find it. Otherwise, maybe it's time to have the deck looked at by a qualified (keyword) technician? -- Ron Bernard Boitrel wrote: > Hi Ron, > > Thank's for your answer. > Actually, this morning, the BX300 began to slow down while playing a > cassette and then I though "Yes, Ron was rigth, the problem is more > likely to be electrical". > I went to the shop to buy an electrical controller and checked the > various points about which you adviced me. > > 1.

The good news is that you may indeed cannibalize the control motor from just about any Sankyo transport. However, the gear mod has *nothing* to do with the control motor, neither does it have anything to do with belts. So, don't let that part of his response confuse you. Sankyo transports were used in the Nak BX, CR and MR series. In addition, the control motor usually responds well to rebuilding, so you may not need a new motor at all. -- Ron Bala Ganesh Chandra wrote: > Hi Paul, > > Decks using the Sankyo transport would be an obvious place to start. > Most other manufacturers also use almost the same motor.

The circuit is the reel motor drive circuit, and the original transistors are commercially "unobtanium", but easy to source from parts donors. You may have a bad reel motor, but to confirm it you need to monitor voltage across R473 2.2 ohm fusible, with an oscilloscope.

Q407 seems to still be on the PCB on the other side, while the TIP42 seems to be piggybacked to it. (Q407 and Q408 have two common pins on the schematic.) A TIP42 should be working fine as it's just a generic equivalent in this place. I doubt this repair job would cause problems though Check if the capstan belt is loose and shake the wire harnesses between the transport and PCB to see if there's a poor connection.

I checked the voltages around that part of the circuit, and they are good, matching what is in the service manual. So perhaps the repair is good, but ugly. The "play" behaviour is rather odd. Initially, after pressing the play button, volume is good in both channels, but then slowly degrades over a period of a few seconds, becoming distorted, decreasing in volume, and then disappearing altogether. Stopping and re-starting playback restores volume and quality. Looking at the schematic, my initial guess (and I am not an EE) is that perhaps one or more of the capacitors in the signal path are faulty. But I would welcome suggestions of what may cause this behaviour.

The circuit is the reel motor drive circuit, and the original transistors are commercially "unobtanium", but easy to source from parts donors. You may have a bad reel motor, but to confirm it you need to monitor voltage across R473 2.2 ohm fusible, with an oscilloscope. Spikes in the waveform indicate brush and commutator wear, causing intermittent shorts. > > tom brucker > > -----Original Message----- >> From: Julian Bunn >> Sent: Jan 14, 2009 9:12 PM >> To: naktalk at naks.com >> Subject: [naktalk] 480 with suspicious circuit mod >> >> I have just received a 480 which I picked up for a few dollars on Ebay, with >> known problems.

I take it that I should look at a mechanical problem first, in this order: 1) Check pinch rollers and tape guides (by inspection?) 2) Check capstan belt not too tight (how?) When I first got the deck I found that the take up reel hub would stop rotating after a short while, especially when playing a tape. After some cleaning of the idler it improved and seems to be cured. But perhaps this is somehow related to the other playback issue?

Rgds, Bala Julian Bunn wrote: Thanks Antoine! I checked the voltages around that part of the circuit, and they are good, matching what is in the service manual. So perhaps the repair is good, but ugly. The "play" behaviour is rather odd. Initially, after pressing the play button, volume is good in both channels, but then slowly degrades over a period of a few seconds, becoming distorted, decreasing in volume, and then disappearing altogether. Stopping and re-starting playback restores volume and quality. Looking at the schematic, my initial guess (and I am not an EE) is that perhaps one or more of the capacitors in the signal path are faulty. But I would welcome suggestions of what may cause this behaviour.

Wasn't the gear mod and upgrade from the original belt drive system? With a gear drive, the motor is locked into the same precise position for each mode. The belt system, which allows for slip, usually means the motor overshoots a little but that is ok. Thus, the wear on the 'rings' is distributed as opposed to have flat spots that the CR7 motor seems to have. I can't say for sure that this is the case for everyone. It was for mine, and rather then clean and put the same motor, I opted to replace it with a like part of a Pioneer Laser Disc player.

(driven by the capstan motor). The gear idler replaces the original rubber idler. Either idler is used to drive the hubs. Neither idler slips, ever. (The gear idler cannot slip and the rubber idler can, but should be replaced if it does.) The required slip during PB or REC is provided by electrical slip in the reel motor. During PB and REC it is supplied by much lowered voltage. This lowers torque,.so it simply doesn't rotate as fast as it would under no load condition. The belt has nothing to do with hub drive. It is used to provide drive from the capstan motor, *(not* reel motor). In single capstan models, it connects the capstan motor to the capstan pulley. In direct drive models, it connects the take-up capstan pulley to the supply capstan pulley. Needless to say, neither of these have anything to do with the control motor, whose role is to drive the control cam. This is the motor the original poster asked about. -- Ron Bala Ganesh Chandra wrote: > Hi Ron, > > You are the CR expert here so do correct me.

I checked the capstan belt and motor. After moving the belt to one side, I found that the motor boss had quite a bit of crud on it, which I cleaned off. The belt seemed slightly slack to me, if anything, and I could very easily move it off true when it was running. After fiddling around with that cleaning and testing, I found that the reel motor and idler no longer work! Pressing Play or FF or Rewind does not engage the reel motor. The problem is maybe with the control mechanism, as it seems to judder a little as if it is not rotating the large toothed wheel sufficiently. Perhaps I need to remove the whole mechanism from the deck and look it all over carefully? Advice most welcome, as usual.

We may also have a confusion of terms. So, please bear with me. As I recall, the M51721L comes with a heatsink attached. The heatsink is the metallic plate, molded to the back of the IC. There are 12 pins coming off the IC plastic package, plus one wire coming off the top and bent to form a 13th pin. Two plastic rivets attach the IC heatsink to the motor stator (a metal plate glued to the PCB, on which four coils and the two sensors are mounted).. Are you with me so far? If so, let's describe the IC replacement procedure in detail. 1- Desolder all 13 pins. This will leave all pins sitting in PCB holes.but free to move. 2- Remove the rivets. Each rivet is comprised of two parts: head/pin and body. Start by pressing on the tiny protrusion of the pin in the back with a small screwdriver, then pull the head out from the front. This will allow you to push the rivet body from the back and pull it out from the front. 3 - Note that there is a thin quartz insulator between the IC and the motor stator. Be* extra careful* not to crack it. Pull the IC body slightly forward, then lift off the PCB. 4 - Remove the insulator, using a thin blade (X-Acto knife is good). *Do not crack it* 5 - Clean the stator mounting surface from remnants of the original heatsink compound. It's been sitting there for 25 years and is probably caked on the surfaces. Use a rag damped with alcohol and repeat cleaning until *absolutely *clean*. *Do the same for both sides of the insulator. Clean the back of the new IC as well. Once cleaned, avoid touching these surfaces with your fingers. 6 - Smear a small amount of heatsink compound on the stator mounting area, making sure it's evenly spread. in a thin layer. Place the insulator on it, properly aligning the holes 7 - Smear some compound on the IC heatsink, again making sure it's evenly spread. Place the IC pins into the PCB holes, align the mounting holes with the stator and insulator, then press in place. 8 - Reassemble the rivets to hold the stator-insulator-IC sandwich together. 9 - Using an Ohmmeter, make sure there is no electrical contact between the IC heatsink and the motor stator. 10 - Solder all 13 pins to the PCB, allowing to cool after each pin. 11- Assemble the PCB to the motor frame, apply power and test. This will tell you whether the original IC was actually bad. Phew... You're done! -- Ron boitrel wrote: > Ron, > > Reading your answer, I realize that something is not clear. > > My IC came without neither the heat sink nor the thirteenth pin !

It's good to see you're both still on the list. I rejoined after an absence of about 5 years. Ron, I still have your list message of 2004 about disassembly/cleaning, and that procedure lasted until a few days ago. My last mode motor came from a BX, and I had to reverse the wires to get the motor to rotate in the right direction (I assume BX transports have the mode motor on the opposite side as the CR7?). I was replacing the belts/idler on my Yamaha K-1020 a few days ago, and I noticed it too has a Sankyo transport--the mode motor looks almost identical! I have a junker I use for parts, so I may cannabilize from that. It's great to see Jeff Galin still doing his thing--Jeff, is that "improved" motor you mentioned markedly different from the original? I must say I am still enjoying my CR7--I bought it as an EBay clunker, and Stephen Sank, and he worked his mod magic on it. The auto calibration is impeccable, and the sound is wonderful. Is Stephen still active? Apart from the mode motor (I use the deck alot doing analog audio restoration), it has been running like a jewel. I recapped my LX3 and it is in my office at work, and my first Nak, a 500 (ca. 1976), is still doing 8 hours a day in my wife's voice studio. What a happy analog life I live! ;-) Best, Paul - > > > Bala Ganesh Chandra wrote: > > Hi Ron, > > > > You are the CR expert here so do correct me.

The eject mechanism is triggered using an inner/outer cable which Is clamped at the transport end by a plastic piece which breaks. The service bulletin on it Is OOD-SI-3115 and is on the wiki pages of Naks.com. Although you can't get the Nak kit you can easily substitute a nut, bolt and washer.

Tapes recorded in that 582 sound fine to my ears when they were playback on the DRAGONs. From my past memory I have IN-SYNC Labs ( realtime 1:1 ) pre-recorded cassette tapes played back on the 582 and they sound great ( IN-SYNC used 582 to duplicate the tapes from their masters though ). These tapes playback on the DRAGON and sound fine as well. Just my 2cents though.          I was told that Crystal Records also use Nakamichi decks to duplicate their masters onto cassettes 1:1 but do not know which model. I speculate that they are modified MR-1s. Just my guess here.       Cheers, Mike   --- On Sat, 1/17/09, Tim Skorick wrote: From: Tim Skorick Subject: Re: [naktalk] Which is the best playback deck?

The 700 ZXL has a tinny sound, like the Revox B215 deck. I actually like the Teac Z-7000 better than the 700ZXLs sound! I have never owned or heard the 700ZXE, so can not comment. Just my evaluation.

If you want the best sounding deck, my order of preference based on my listening tests( subjective, of course!), with no money spared is 1. 1000ZXL 2. XX9 3. 680ZX 4. Dragon and 5. The CR7 The above is assuming that the decks are properly serviced and calibrated.

When playing the tape, the output of the song will slowly decrease until its volume is very low. If I press the stop button and then play it will play at normal output, but will again start dropping. Anybody know what is behind the copntrol buttons. I opened it up and saw a circuit board which obscured vision to anything behind the buttons ie. switches that might need cleaning. THis has happened with different tapes and I know it isn't the tape. Do the buttons behind the panel just pull off ie. the output, bias, left and right buttons etc. I would need to pull these in order to remove the front cover in order to clean all the switches and buttons. Anybody have an idea what could be causing this. Thanks. -------------- next part -------------- An HTML attachment was scrubbed...

But a mis- calibrated 700ZXL does indeed sound tinny. in fact, that seems to be a trait of the 700 in all its flavors -- they do not seem to take even the slightest mis-calibration without becoming tinny, shrill or dull. The 1000 series and my beloved 600 series seem far more tolerant of calibration errors. I like my Revox B710 very much, but it lacks that intangible something that gives me a passion for my favorite Nakamichi decks. The Revox B215 seems to render a recording drier than many Nakamichis and lacks a sense of solidity to its bass; in contrast the older B710 has much more defined bass but it has that sterile, well- defined but boxed-in treble that characterises many Swiss-made recorders, although not as acutely as Nagra, which I cannot stand the sound of.

Otherwise, you will have a unit that always seems to give problems and end up being a bench queen. Remove the transport, and check all the known spots such as the pinch roller mechanisms, the cams, capstans and idler. There has been much written about the mechanism here on Naktalk so it is a valuable resource! After fitting the mechanism, make sure that the mechanism alignment is all properly done (as per the SM) so that transport operating is silent but crisp. Nak transports are nice because they are silent and smooth and do not make any loud noises like Aiwa does. If at all this is not your cup of tea, get a good tech to do it for you, Rgds, Bala 2009/1/16 Julian Bunn Hi Bala, Yes, cleaned and checked those: they seem to move freely and work correctly, at least to my inexperienced eye. I checked the capstan belt and motor. After moving the belt to one side, I found that the motor boss had quite a bit of crud on it, which I cleaned off. The belt seemed slightly slack to me, if anything, and I could very easily move it off true when it was running. After fiddling around with that cleaning and testing, I found that the reel motor and idler no longer work! Pressing Play or FF or Rewind does not engage the reel motor. The problem is maybe with the control mechanism, as it seems to judder a little as if it is not rotating the large toothed wheel sufficiently. Perhaps I need to remove the whole mechanism from the deck and look it all over carefully? Advice most welcome, as usual.

I checked the voltages around that part of the circuit, and they are good, matching what is in the service manual. So perhaps the repair is good, but ugly. The "play" behaviour is rather odd. Initially, after pressing the play button, volume is good in both channels, but then slowly degrades over a period of a few seconds, becoming distorted, decreasing in volume, and then disappearing altogether. Stopping and re-starting playback restores volume and quality. Looking at the schematic, my initial guess (and I am not an EE) is that perhaps one or more of the capacitors in the signal path are faulty. But I would welcome suggestions of what may cause this behaviour.

Rajiv originally said that the CR-7 and Dragon "are a bit out of my budget". He asked mainly about DR1 and Cassette Deck 1. I haven't heard a DR-1 but I do have a Cassette Deck 1. Its playback is tolerably good, not up to the ZX-9 but still Nak quality in the average range.

We are not debating which Nak sounds better in general, we are discussing which Nak is best to use for archiving material recorded in the past on unknown machines with unknown settings and capabilities - and Bala responded with comments right on topic. Can we all please focus on the specific topic as per the request of the original poster - and keep all 700, 1000, 600, ZXL, Limited Gold editions, etc. out of this discussion, since this is not the information required - I seriously doubt someone will take a 1000 ZXL and start fiddling with the playback azimuth for each bit of dirty old tape thrown at it. The poster had very specific questions, which no one seems to have responded to - and I can't, since I have no experience with the machines he was asking about: So which is better between Cassette Deck 1 and DR-1 and/or DR10 ? Is the CR-7 and Dragon performance worth the extra money in comparison to the other three just mentioned taking into account what they will be used for ? Can someone provide a useful response without going on another tangent, please ? Thanks, George On Mon, Jan 19, 2009 at 10:43 AM, wrote: > HI Bala, I am getting cofused!

Using the manual eq. selection while copying to CD may help you like a noise filter (you can do this with a piece of scotch-tape for the auto selections) if there is too much noise for the standard tapes recorded without dolby, but this is up to you. Having a playback azimuth will help you to have a clear sound especially for the tapes recorded in different decks. All of the Nakamichi decks have a frequency respose 20 - 20.000 Hz for the standard tapes (which is written on their manuals) so there is no problem for the model number having playback azimuth selection. Find one which is in technically good condition. As far as I know DR1 is the last one having playback azimuth correction.

The water fell on the main logic board and allowed 12vdc to get to the first logic processor and killed it. No transport function was the results. I am looking for a CR 7A parts unit for cheap or just a harvested logic board would do from a junk CR 7A Any body got any clues ?

In-Reply-To: Message-ID: <789247.36794.qm@web30203.mail.mud.yahoo.com> Hi Ali, I may not have phrased myself correctly, but let me try again. The 1000ZXL brings the best out in any tape. With pre-recorded tapes it gives an awesome sound, but does not reveal all the information present on the tape. That is a subtle, but audibly considerable difference. I use a CR7 and 1000ZXL actively, and on several occasions put them head to head.. The ZXL takes any tape, and makes it sound really good and makes it sound as deep and huge as the original material allows. The CR7 on the other hand, concentrates more on retrieving the information out of the tape thanks to the azimuth adjustment. I feel it is more suitable when you have that once chance to glean every bit of information off the tape. The 1000ZXL is a totally different machine. When you throw a cassette recorded on a well aligned deck, it beats the CR7 hands down. You could, with a small trimmer and your ears, adjust the azimuth on the ZXL and get it to make every tape sound awesome. But when you have a large number of tapes, well it's not too practical. In terms of the decks Rajiv mentioned, I would personally prefer the DR1. It has a better build and sound. It has a azimuth adjust, and a good and trouble free transport. While the Dragon is a very nice sounding machine, the CR7 seems to have a more transparent and open sound. I guess being a male, I also like to feel more in control and the manual azimuth control makes me feel so ;) So there it is! Rgds, Bala BOEING747600 at aol.com wrote: HI Bala, I am getting cofused!

Message-ID: <364410.14985.qm@web36808.mail.mud.yahoo.com> Hi friends, I recently acquired an LX-5 and was blown away by the sound of this machine as compared to the revered decks like CR and Dragon. All it needed was a belt which I replaced from ESL and adjusted speed with the T100 and the 3Khz. test tape from Luis. The same is true of the ZX7 and the ZX9 series decks. The sound is as good as a CR7/Dragon( sometimes better bass!) after the azimuth adjustment/NAAC. Why is this so? In fact these three decks that I have, have no issue playing tapes recorded anywhere with any  azimuth aberration. Even budget Indian prerecorded cassettes sound superbly crisp with their fixed playback head. The 1000ZXL does the same too, but then one expects a deck of that caliber to outperform everything else. Why have the ZX7 and LX5 decks been so under rated? Is it me or others have similar observations? Even ebay sales shows the ZX7 and LX 5 sell for a song most times. Jeff Galin, your input on this would be appreciated! Love to hear varied opinions on this matter. Regards, Ram -------------- next part -------------- An HTML attachment was scrubbed...

I was intrigued by the topic of automatic azimuth adjustment a la Dragon, vs. manual as found on CR-7 and DR-1. So, without discussing these decks' "sound" -- a topic I find a bit elusive, as the fine differences between "exalted" Nak models and more basic ones are often way-secondary to the range of quality, sonic balance, spatiality, etc of the source material we feed into them (Just my 2 cents, folks!)...here is my opinion on auto vs manual. Before stating it, I should say I have more than 15 years of experience with the CR-7, and some recent experience with a DR-1, as well as some "fitful" experience with a Dragon which had some tape eating proclivities that I'm guessing were not related to the auto azimuth system. Back in the '90s, I was using the CR-7 extensively for production in my studio involving material from cassettes recorded on many different decks, both my own, and those belonging to radio stations, other studios, private individuals, the lot. As you might imagine, there was a very mixed bag of quality to deal with, azimuth being only one of the concerns. I've always been a stickler for dead-on azimuth, especially when it concerns the clear reproduction of my voice. A serious consideration back then was that, while azimuth discrepancies could often pass without notice on FM-Stereo broadcasts, a careful producer also knew that sometimes the product, even if broadcast in stereo, could well be listened to in MONO, as in table radio, or mis-set FM tuner, or intentional switching to mono in cases of marginal reception, car radios doing it automatically, etc. Without regard to what bad azi does to music, I'd say that an announcer or narrator's voice could become unpleasant to listen to when the swishy or phase-y effects of sloppy azimuth were shown up in mono. Most listeners would not say, "Aha! Bad azimuth." But they would, at some level, be aware of a muffled tone or lack of "presence." Also a very bad idea when sending out samples of one's work to producers... Say what you will about CD, it did remove a mess of variables at the listener's end (poorly maintained cassette decks, bad azi on the recipient's deck, ignorance as to Dolby settings...and on and on). BUT...even with CD, if what you produce came from cassettes of flawed azimuth, the same problems described above would be present. Perhaps they'd call even more attention to themselves. So, before they went into a production, I played all cassettes on the CR-7, combined the stereo signal to MONO at my console, and tweaked the azi knob until the presence was identical when switching between mono and stereo. Only then, would I switch back to stereo and record the cassette's contents onto DAT or reel (or, later, CD-R or digital editor). I was thus absolutely certain of maximized presence of all cassette-based elements in a production. Many years later, somewhat influenced by its "exalted" reputation, I added a Dragon to my system. The disappointment was -- and I will concede to it being a bad sample of the Dragon if any of our tech members strongly feels that to be the case and can prove it to me by making this deck perform to my azi-satisfaction! -- the infernal beast had the fidgets regarding continuously moving the PB head around to chase the azimuth. Thus, when check-monitoring in MONO, as described above, the audio was a feast of swishiness every time one entered play from stop. I might add, it was not the tapes, as the same tapes played start to end in phase, after an initial tweaking of the CR-7's or DR-1's azimuth control. Again, this might have escaped attention on much material when listening in stereo or with wax in one's ears. So, my experience, at least, on this one Dragon, was that sometimes high-techy stuff leaves the world of the practical for the realms of theoretical perfection...and leaves a gap in real world performance. Just my experience...and, again, based on only one Dragon. But I'd be curious if anyone else has experienced this continous azi-chasing on tapes of known azimuth consistency when using a Dragon for PB.

The CR-7, DR-1 and CD-1 all have manual playback head azimuth adjustment while the DRAGON has automatic adjustment. The same applies to tape calibration. Some decks use fully automatic tape calibration such as the A.B.L.E. of the ZXL series from Nak as well as some TOL Non-Nak ( such as TEAC Z-7000, Hitachi D-2200M, for example ) while others use manual adjustment such as the ZX series from Nak and TEAC C-6000 from Non-Nak for example. Any Forum member could dare to discuss the advantage and disadvantage of each of the two designs in terms of " automatic vs manual "? I think this could be a more interesting topic to talk about.

In my opinion, Playback Azimuth adjustment is essential for tapes not recorded on my deck, including pre-recorded tapes. As I turn the Playback Azimuth knob, the music will gradually 'open-up' until it reaches its optimum clarity. Without this capability I would be hearing very dull-sounding music from a lot of tapes. I would not be without Playback Azimuth adjustment, as I certainly wouldn't want to manually adjust the head azimuth screw for each tape! The Cassette Deck 1 turns up on eBay for (usually) sensible money and I can recommend it as a very useful tool for archiving.

URL: From emberphoto at hotmail.com Mon Jan 19 20:15:57 2009 From: emberphoto at hotmail.com (Steve Ember) Date: Mon, 19 Jan 2009 14:15:57 -0500 Subject: [naktalk] Best sounding decks -- Easier to read! Message-ID: Hello, all... Sorry for the unwieldy version sent earlier, as result of keeping all previous posts. You can read this one without scrolling three feet! I was intrigued by the topic of automatic azimuth adjustment a la Dragon, vs. manual as found on CR-7 and DR-1. So, without discussing these decks' "sound" -- a topic I find a bit elusive, as the fine differences between "exalted" Nak models and more basic ones are often way-secondary to the range of quality, sonic balance, spatiality, etc of the source material we feed into them (Just my 2 cents, folks!)...here is my opinion on auto vs manual. Before stating it, I should say I have more than 15 years of experience with the CR-7, and some recent experience with a DR-1, as well as some "fitful" experience with a Dragon which had some tape eating proclivities that I'm guessing were not related to the auto azimuth system. Back in the '90s, I was using the CR-7 extensively for production in my studio involving material from cassettes recorded on many different decks, both my own, and those belonging to radio stations, other studios, private individuals, the lot. As you might imagine, there was a very mixed bag of quality to deal with, azimuth being only one of the concerns. I've always been a stickler for dead-on azimuth, especially when it concerns the clear reproduction of my voice. A serious consideration back then was that, while azimuth discrepancies could often pass without notice on FM-Stereo broadcasts, a careful producer also knew that sometimes the product, even if broadcast in stereo, could well be listened to in MONO, as in table radio, or mis-set FM tuner, or intentional switching to mono in cases of marginal reception, car radios doing it automatically, etc. Without regard to what bad azi does to music, I'd say that an announcer or narrator's voice could become unpleasant to listen to when the swishy or phase-y effects of sloppy azimuth were shown up in mono. Most listeners would not say, "Aha! Bad azimuth." But they would, at some level, be aware of a muffled tone or lack of "presence." Also a very bad idea when sending out samples of one's work to producers... Say what you will about CD, it did remove a mess of variables at the listener's end (poorly maintained cassette decks, bad azi on the recipient's deck, ignorance as to Dolby settings...and on and on). BUT...even with CD, if what you produce came from cassettes of flawed azimuth, the same problems described above would be present. Perhaps they'd call even more attention to themselves. So, before they went into a production, I played all cassettes on the CR-7, combined the stereo signal to MONO at my console, and tweaked the azi knob until the presence was identical when switching between mono and stereo. Only then, would I switch back to stereo and record the cassette's contents onto DAT or reel (or, later, CD-R or digital editor). I was thus absolutely certain of maximized presence of all cassette-based elements in a production. Many years later, somewhat influenced by its "exalted" reputation, I added a Dragon to my system. The disappointment was -- and I will concede to it being a bad sample of the Dragon if any of our tech members strongly feels that to be the case and can prove it to me by making this deck perform to my azi-satisfaction! -- the infernal beast had the fidgets regarding continuously moving the PB head around to chase the azimuth. Thus, when check-monitoring in MONO, as described above, the audio was a feast of swishiness every time one entered play from stop. I might add, it was not the tapes, as the same tapes played start to end in phase, after an initial tweaking of the CR-7's or DR-1's azimuth control. Again, this might have escaped attention on much material when listening in stereo or with wax in one's ears. So, my experience, at least, on this one Dragon, was that sometimes high-techy stuff leaves the world of the practical for the realms of theoretical perfection...and leaves a gap in real world performance. Just my experience...and, again, based on only one Dragon. But I'd be curious if anyone else has experienced this continous azi-chasing on tapes of known azimuth consistency when using a Dragon for PB.

Dragon once aligned correctly can do the magic playback to many of the tapes unless the tapes themselves way off the correct azimuth as even Dragon has limited azimuth angle correction ( quite sufficient for 99 % of the tapes) Dragon also needs constant use to keep it working properly. If you have obtained your Dragon form another user - good chance it had not beeen used much causing alll sorts of problems. The main one is related to NAAC issues. The tape eating is one of the major symptoms of Dragon NAAC problems - I cannot vouch that your Dragon can be restored completely but from my experience, 90-98 % the Dragons can be restored to work as it should. It needs good amount of manual labor and some very important parts and tools. can be expensive.

Need for advice...... Message-ID: <4974DB17.10706@otenet.gr> I have a problem with one of my my Dragons which just came up: While trying some used pre-recorded cassettes recently bought on ebay i noticed that NAAC does not function on the reverse mode. When i playback forward the green led is flashing and then stabilizes while the sound is coming up nice and clear as it should be.....even though with a small delay...When pushing reverse (while on play forward mode) then the sound (very fast) turns down and i hear a blare sound like heads are completely dirty......also the green led does not blink and i assume NAAC does not function ... . I did some cleaning -demag and tried some tapes recorded on my well calibrated 680, but the problem is still there......also the newly purchased pre-recorded tapes sound just fine on other decks i tried them on (Revox B-215 etc) One more thing i noticed is that when i start playback directly in reverse mode then i hear the music starting almost OK but after 1-2 seconds it drops down ending in hearing nothing but a blare sound (and NAAC led does not function either). I have come up to the conclusion that my Dragon suffers a NAAC problem......I am certain someone out there must have faced such problem with a Dragon...Please help, any suggestions on how to fix it and what to look for, while doing it, will be highly appreciated......

Remember the ZXL only moves the record head in Azimuth adjustments and the play head stays fixed. So on one ZXL, if the play head is different to another ZXL, then while both machines will align the record to their respective play heads and record well, playback of the tape from one to the other will be flawed. Running the Azimuth align on the second deck will only move the record head to the correct position (for that tape) but your play will still suffer. In essence Nak did two versions of Azimuth adjust: 1) Move the record head to match the play - ZXL 68X etc 2) Move the playback head to match the record (CR7, DR1 etc) which has the added bonus of being able to adjust to tapes recorded on another deck. While the dragon moved the play head, it does it automatically, which could be considered their third method. Unless all your ZXL's have their play head in the same position, you could have an issue swapping tapes between them.

It appears to me that the pinch roller is "rounded" at the edges and it is causing the tape to drift inwards (towards the deck) which causes all sorts of azimuth issues. It only seems to do this on certain shells (late XLII-S in particular). I think replacing the CA80005A assembly will fix this issue. Of course, any Sankyo single-capstan deck will have this part, and wouldn't you know it, I gave away a BX-100 a few months back! In addition, the deck is missing two of the standard gold-colored philips head chassis screws that secure (among other things) the faceplate to the chassis. Can anyone help me procure these parts cheaply? Thanks. -jb -------------- next part -------------- An HTML attachment was scrubbed...

But it does not, because most of us only see a set of indicators that light up as the deck proceeds during automated calibration. There is a stark difference between the ABLE system, and the system used on the Teac Z700, Aiwa AD-F990, Hitachi 2200M and some other decks that did automatatic calibration. Even between manufacturers, the execution differed a little which leads to the question as to how effective their implementation of the system is. The reason for me saying that the ABLE is quite different is that it uses more then one frequency perform the various steps. However, all systems are handicapped by one fact. They rely on digital control, which allows these systems to be possible but puts them at a distinct disadvantage. Because digital control allows output to be in pre-defined steps, values can only be in certain steps, with a fixed resolution. Even the 1000ZXL has a fixed number of eq combinations (64 to be precise) and fixed number of bias steps. The best solution, theorectically, would be manual controls which allow in-finite adjustment possibilites that the user would tweak to their hearts content to get the best possible performance out of the tape fed to the machine. This however, can be a cumbersome exercise and calls for a variety of factors such as user experience, time, and equipment at hand. Even with all these available, not all decks allow ready access to all the required controls. The automated solution, while having its drawbacks, has brought the otherwise complicated and sometimes frustrating process of tape calibration literally to our finger tips. It's as easy as loading the tape and hitting one or a combination of buttons. We thus can perform calibrations as many times as we want, thanks to the automation. Both systems would have its followers and nay-sayers. What I have said above are entirely my own observations. I openly welcome all manners of discussion, comments and criticms on my views and this subject. Rgds, Bala LENA WONG wrote: Jason: With that in mind, let bring out one discussion over here and that is " automatic vs manual adjustment " as well. The CR-7, DR-1 and CD-1 all have manual playback head azimuth adjustment while the DRAGON has automatic adjustment. The same applies to tape calibration. Some decks use fully automatic tape calibration such as the A.B.L.E. of the ZXL series from Nak as well as some TOL Non-Nak ( such as TEAC Z-7000, Hitachi D-2200M, for example ) while others use manual adjustment such as the ZX series from Nak and TEAC C-6000 from Non-Nak for example. Any Forum member could dare to discuss the advantage and disadvantage of each of the two designs in terms of " automatic vs manual "? I think this could be a more interesting topic to talk about.

To: "Talk about Nakamichi Cassette Decks" Date: Monday, January 19, 2009, 7:08 AM I use a Cassette Deck 1 for listening via a Little Dot valve headphone amp, and archiving directly to a Marantz CD Recorder. In my opinion, Playback Azimuth adjustment is essential for tapes not recorded on my deck, including pre-recorded tapes. As I turn the Playback Azimuth knob, the music will gradually 'open-up' until it reaches its optimum clarity. Without this capability I would be hearing very dull-sounding music from a lot of tapes. I would not be without Playback Azimuth adjustment, as I certainly wouldn't want to manually adjust the head azimuth screw for each tape! The Cassette Deck 1 turns up on eBay for (usually) sensible money and I can recommend it as a very useful tool for archiving.

Message-ID: <211ca5a30901192306w209764d5wab6326f4ad6ec721@mail.gmail.com> Earlier, I posted that I'm doing some DIY work on an RX-202, and that I'd like to replace the pinch roller. That's still the case, but I wanted to elaborate why and was wondering if anyone else has seen anything like this. The deck works extremely well and sounds great with every cassette I've thrown at it - except one. The "last version" Maxell XLII-S - the grey one with the smaller window and gold trim around the window. It's a heavy tape, and it's got the "High Resonance Damping/Heat Resisting" (HR-HR) mechanism. When I play any of those tapes, in either 90 or 100 length, I can see the tape between the rec/play head and pinch roller deflecting inwards towards the deck (this deck is especially easy to watch the tape as it is transported). The reason why I suspect the pinch roller is that it looks "rounded" to me compared to the rollers in my 480 and MR-1 and non Nak decks. Applying a little pressure outwards to the pinch roller assembly as the deck plays alleviates the tape drift somewhat. Other Maxell cassettes, including the previous model XLII-S and MX with the "SS-PA" mechanism work and sound fine. Cheap TDK D tapes work and sound fine. Sonys, Fujis, all fine. Just these HR-HR XLII-S don't track well, and I've now tried five examples of them. Does anyone have any wisdom to share with me about this unusual behavior? The only thing that "looks" off to me is the pinch roller. Thanks in advance. -jb -------------- next part -------------- An HTML attachment was scrubbed...

I also play tapes back on the deck that originally recorded it so it should be pretty good.? If I were to sell a deck though, I would have a problem so perhaps the azimuth may be out a touch.? Would a possible solution be to leave 30 seconds of blank tape per side when recording, so that prior to playing back on a different machine, I could adjust the azimuth perfectly which takes 2 seconds on the ZXL,?then listen to the music recorded?? Don't the manual controls say on a ZX-9 just use the same logic / systems?( A.B.L.) ?to achive the same result but with manual intervention??

Jason: ????????? With that in mind, let bring out one discussion over here and that is " automatic vs manual adjustment " as well.? ? ??????????The CR-7, DR-1 and CD-1 all have manual playback head azimuth adjustment while the DRAGON has automatic adjustment. ? ????????? The same applies to tape calibration. Some decks use fully automatic tape calibration such as the A.B.L.E. of the ZXL series from Nak as well as some TOL Non-Nak ( such as TEAC Z-7000, Hitachi D-2200M, for example ) while others use manual adjustment such as the ZX series from Nak and TEAC C-6000 from Non-Nak for example. ? ?????????

To: "Talk about Nakamichi Cassette Decks" Date: Monday, January 19, 2009, 7:08 AM I use a Cassette Deck 1 for listening via a Little Dot valve headphone amp, and archiving directly to a Marantz CD Recorder. In my opinion, Playback Azimuth adjustment is essential for tapes not recorded on my deck, including pre-recorded tapes. As I turn the Playback Azimuth knob, the music will gradually 'open-up' until it reaches its optimum clarity. Without this capability I would be hearing very dull-sounding music from a lot of tapes. I would not be without Playback Azimuth adjustment, as I certainly wouldn't want to manually adjust the head azimuth screw for each tape! The Cassette Deck 1 turns up on eBay for (usually) sensible money and I can recommend it as a very useful tool for archiving.

Message-ID: <0KDS00MQ9GV43327@vms173003.mailsrvcs.net> Tom, I've been lucky enough to have owned three Naks over the last 25 years. A BX300, CR7A and currently a Dragon. I'll stay on topic and just offer an opinion on which Naks works better with azimuth correction. Now, as you and others have pointed out, no Nak will perform to its optimum if not service properly. The CR7A was a very, very capable machine for recording and playback. The auto-cal worked great and playback sounded great. My Dragon is also a very, very capable machine for recording and playback and the NAAC works flawlessly. Both sounded great but once again, I'll stick with the azimuth adjust. The problem with most people ears are they are faulty and rarely can pinpoint a 'center' of any soundstage and this was the problem that I found using the manual azimuth adjust of the CR7A on a tape recorded on another deck OR a store bought NEW cassette. Of course, my store test tape was a the Type I variety. I never, ever could adjust the azimuth of the CR7A by ear. I'd hit PLAY, close my eyes, adjust the azimuth for best sound 'by ear' and never would it align with the bar display nor could I find a setting where I found it pleasing. Now, I throw the same tape into the Dragon and it totally blew away the CR7A and not by a small margin. To remain on topic concerning the best deck for playback alone, the Dragon just does so much a better job than using the manual adjust and 'my aging' ears to properly adjust. Just my opinion and experience of once owning a CR7A and currently a Dragon but admittedly not claiming that either had been properly serviced.

The pinch roller arm is perfect - the pivot is clean and free moving. The tension feels OK but I have no real way of checking it. The roller isn't in good shape for sure. I realize that you shouldn't necessarily do this but I didn't have much to lose, so I scrubbed it with denatured alcohol (no real difference) and then used some rubber renew on it (also no difference). The rubber surface IS convex sighted along a square. I have no idea what would cause a pinch roller to do that, but sure enough, that's what has happened here. The pivot bracket holding the roller appears to be fine with no trauma. I think my next step is to replace either just the roller, or the whole roller/pivot assembly. I assume that if I am careful I should be able to replace this part without a realignment of sorts. My real question is - why is the problem exacerbated by what I would assume is a high-end cassette with a high-end shell? -jb On Tue, Jan 20, 2009 at 1:26 PM, Ron wrote: > > I wonder if the pinch roller arm is binding due > to dirty pivots and/or if the pinch roller surface > is glazed. > > I don't recall ever seeing a bad pinch roller in > this transport type.

For archiving, personally I'd first try my ZX9 or Arcam as the source, and would expect them to be much the same giving an excellent performance (they replay each other's recordings rather well - not spot on but very well all the same) always provided: a) the deck on which the tape was originally recorded isn't far different, and b) the recording hasn't faded. If there is a problem with the azimuth, the ideal would be, IMHO, the CR7 with its adjustable azi' Failing that, the others with manual adjust, the choice depending on budget. But for dull tapes - personally I forget the Naks and revert to my old and trust Pioneer CTS830S every time and switch in its wonderful FLEX circuit. Sacrilege it may be to say this, but I also find it does a very good job with tapes made on machines where the azi' would normally require adjustment to bring out its best. That particular model of Pioneer is a much underrated deck in some respects - e.g. w/f, where it beats most Naks. It competes well on s/n. Its weakness, IMO, is that it just doesn't generally sound so good as my ZX9 (or Arcam)! But it sounds better than both when it's replaying a dull old recording, and they can be picked up on eBay for very little money.

Some brand tapes are closer than others. All the new tapes do have a difference between side a and b. Again some are closer together than others. The worst for me was the Maxell MS 90s. But I got a horrible batch. Out of 20, 6 were completely unusable. I sent them back to Maxell but no replacements yet. Much better luck with the new TDK SA90s.

It is very unlikly for bad orange caps to cause a high frequency roll off as they are mostly used in for coupling. A mis-aligned head, or badly tracking transport is more the cause of it. Bad caps start to hiss, crackle and pop through the speakers.

After taking the cover off I noted the 2 fuses were intact but there was a suspicious brown residue on the top belt drive motor. Would a burnt out belt drive motor on the 125 trigger a signal to the Nakamichi IC chip to prevent a power up while the motor gets replaced?   Ninth Confuguration Stay connected to the people that matter most with a smarter inbox.

I had recently picked up a cosmetically mint CR-7A with all original packaging, manual, brochure, cloth and both the RM-5 and RM-7c for $100.00 locally. It seems as if it was purchased and set aside long ago and the seller had recently tried to use and found it to be none functional. It is an earlier model, manufactured in the 3rd quarter of 86' with serial number in 7000 range. After I got it home I proceed to power up and the only thing that happens is the stop button lights up green, but no other display lights. Also none of the function buttons induce any operation. I decided to pop of the cover and look to see if I could see anything amiss visually. Very clean inside with no obvious signs of problem. I do have another fully operational CR-7A and the non-working one looks to be the same inside. Any ideas on what the problem might be folks? I had already talked to Willy before the holidays on sending down some of my Naks for maintenance and repair on a Kyocera. Think I should send this one off first, or is there something I might be missing.

Those decks are meant to be used. I'd say you have a bargain find that is worth spending what it takes to fix up. It will still be cheaper than a nice example from ebay provided nothing catastrophic happened to it that you don't know about. Go for it!

If you do not want to exacerbate (make worse) the condition then it is suggested that poking and prodding be totally avoided. The right course of action IMHO is to send it immediately to one of our repair gurus here and have them do a diagnosis and service. -------------- Original message from mpcurless at comcast.net (Mike Curless): -------------- > Hello all, > Long time subscriber and first need to post question to you folks.

Possibly, a fuse is blown. If so, it's possible that after a long time of non-use, the deck should have been brought up gradually on a variac, rather than just plugged in and switched on, but is otherwise OK. Assuming you have a multimeter, check all fuses on the Power Supply PCB and replace as necessary. Then,. power through a variac and raise voltage gradually and slowly. Lacking a variac, you can try to power the deck in series with a 25W lamp. After an hour or so, change to a 40W lamp. Some time later, change to 60W. Then, plug it directly into a power outlet -Good luck, -- Ron Mike Curless wrote: > Hello all, > > Long time subscriber and first need to post question to you folks.

It is very weak in driving the tape in either FF or REW. It will drive, albeit very weakly if there is not much load on that particular spool (right spool for FF, left spool for REW. If there is a load (most of the tape on one side or the other), it won't drive the tape at all. Through forums, I learned this was usually and idler tire issue. I bought the tire and when I went to install, it, I found that my deck had a gear mechanism, not the idler tire set up. The gear mech seems to function OK. I my drive motor shot? The deck seems to playback fine... I'll greatly appreciate your insights. Greg -------------- next part -------------- An HTML attachment was scrubbed...

Message-ID: Its been a long time since I posted but I see the old names are still here. i hope you are all in good health and spirits. Update and Questions: I now have a unserviced but perfect BX300e my original & serviced 481z, a serviced 670zx, a perfect Cassette Deck 1 and a new to me 580 en route. I do not need so many and its largely due to my turning friends onto Naks that I ended up with some spares as I get pressure to sell one of mine off to give them their first Nak. We are also rearranging the house so dont need so many stereos set up here and there. However now I am under pressure from 3 friends to get them a Nak. Most of them are musicians with many live recordings etc and cassettes from various machines which they want to gain max access too via naks. As far as they are concerned Im 'IT' when it comes to tape machines ..... but Im a simple arts graduate with a mispent youth behind him and had time to listen and learn. partly from this forum over the years ... so I have not learnt to service my own Naks or change belts so in answering try to factor maintenance issues in please. Which ones do I part with? I'm keeping the 670 (well obviously) the 300 is reportedly a simple and robust model with its DD motors and I think it has the gear upgrade (not sure). The Cassette Deck 1 has its playback azimuth The 580 needs changing to UK voltage from US 110v or using with a large iron lump attached to it. I dont know the sonic character of the 580 series . or the condition of this one but it comes from a hifi buff, unused for some time I gather, The 481z is built like a tank and holds much affection for me but is probably a good one to sell, serviced and set up for some years. Mostly the recipients do not have what buffs would call hifi but as I say are musicians who want to get at their old stuff - a desire I fully support thus its mostly playback they need. So comments about wether the 110 v transformer can provide 240v take outs would also be helpful. Shown a photo I can do that sort of thing but can also get it done pro nearby if its tricky to get right.

However, the reel motor most common failure occurs in Play mode, not in FF or REW. Because of this, I would check to make sure there is nothing wrong in the mechanical linkage from motor pulley to gear idler to tape hub. If found to be OK, I would check the motor drive voltage in FF and REW. If less than 9V or so, the problem could be electrical. -- Ron Greg Handakas wrote: > Hi all, > I am new to the mailing list and have a question.

I found TWO "parts decks" locally for very little money - a BX-100 and a BX-1, and had to have them both of course. Well, it turns out the only thing wrong with the BX-1 was a counter belt that had stretched and someone had wrapped around the take up reel AND the brass reel motor pulley, so that play and fast forward kinda worked, and rewind did the same thing as fast forward. I pulled the bad counter belt out (this restored normal operation except for the counter, of course) and will order another one to fix it. Wow - for the cheapest Nak ever marketed, the BX-1 sure sounds pretty good! The BX-100 on the other hand has some pretty major issues but at least the pinch roller was good. Replacing the roller in my RX-202, AND ensuring that the well backplate was seated correctly especially on the pinch roller side, seems to have solved my issue with mistracking modern grey shelled XLII-S. -jb On 1/24/09, shanti ramachandran wrote: > > Yes Kevin he does Naks too.

After rewinding a tape or fast forwarding then pressing stop the machine would switch to play and pause at the same time and then go back to stop.  This happened for a few weeks then suddenly while listening to a tape the machine stopped by itself and then went into play and pause at the same time and now the machine just constantly switches by itself between stop and play/pause.  I powered down the machine and powered it up again but it still just constantly switches itself between stop and play/pause, whatever button I press it makes no difference. The heads do not engage but both capstans are still turning. I can here a click when the machine is switching itself between stop and play/pause. The machine has always been reliable until now. I have not removed the top to have a look as I don't really know what  to look for or if I can do anything. Has anyone come across this problem before?

After rewinding a tape or fast forwarding then pressing stop the machine would switch to play and pause at the same time and then go back to stop.  This happened for a few weeks then suddenly while listening to a tape the machine stopped by itself and then went into play and pause at the same time and now the machine just constantly switches by itself between stop and play/pause.  I powered down the machine and powered it up again but it still just constantly switches itself between stop and play/pause, whatever button I press it makes no difference. The heads do not engage but both capstans are still turning. I can here a click when the machine is switching itself between stop and play/pause. The machine has always been reliable until now. >I have not removed the top to have > a look as I don't really know what  to look for or if I can do anything.

Radio shack have both 6v and a 12v micro light bulbs you have to be little creative however! to shorten the leads from the new lamp/bulb from Radio Shack. Hope this help you when you decide to replace the lamp in the cassette well. The bulb is behind the the metal plate in the front of the cassette well , there are 2 or 3 micro screws that you need to unscrew in the cassette well to get to the light. The CR 7A will look great! and mint and let you see how much tape is left in the cassette well without straining the eyes :) Thanks! Ali In a message dated 1/26/2009 3:40:50 A.M.

It was a small LED supplied by a hearing aid battery. It worked well, and lasted indefinitely, I don't recall one ever going out. I may even have them stuffed in a drawer somewhere....

The lamps they have (or used to have) are rated at 14V. Driven by the deck's 12V, they should last forever and a day. For those that have never done this: be extra careful when removing the colored cap from the old bulb.

I removed the original tiny PCB that holds the original lamp, and replaced it with a piece of breadboard. The effect is quite nice and according to those who have seen an original RX-202 lamp in operation, similar in illumination. I have some photos of the deck with the new illumination posted on tapeheads.net in the cassette forum under "Nakamichi Eye Candy." -jb On Mon, Jan 26, 2009 at 10:12 AM, Willy Hermann Services wrote: > I just recently replaced the cassette well lamp on a CR-7A with a warm white > 3mm LED.

I have printed off all your instructions from "tapeheads" and will open it up and will have a go at repairing the deck at the weekend. I love this deck, it still sounds superb and records brilliantly and I especially like the pitch control which allows me to play back all my old tapes from the 70's at the correct speed, which for some reason my then Marantz 5220 recorded at a slower speed.

He's had my ZX-7 (A124 14038) for the last 22 months. My last posting on this problem was last summer when I asked the Naktalk group for help to get my deck back. I paid $400 for it, so I'm not talking about some cheaper 2 head Nak which we know can go for under $50. Scott stated in an email to me June 30th that he'll get the deck out that week. Since then I have not heard from him. I sent a certified letter (signature returned) to him in November simply stating to send the deck back, but no luck. I also sent him three emails a few weeks ago stating that I'll be driving thru the L.A. area and I could pick up the deck, but again no response. The Naktalk group tried to help me last time. One gentleman even made searches for phone number contacts. Once again, I feel someone in this group has his phone number, since there's techs and other guys in contact sharing info in fixing equipment. Please, if anyone can help. - Mark Exstedt 602-243-4118 (United States) The following is where this subject left off last summer: This is Scott's comments on my tape deck. Please also look up the link to which he posted: Your ZX-7 was damaged during shipping that I didn't realize until later. It was a small crack on around one of the mounting screws for one of the circuit boards. I repaired the broken traces, but, have not figured out how to secure the board well enough to survive shipping. I have taken a picture and posted it on the web. http://www.nakremotes.com/nakremotes/Images/Mark_ZX-7/Mark_ZX-7.htm _________________________________________________________________ Windows Live™ Hotmail®:…more than just e-mail. http://windowslive.com/explore?ocid=TXT_TAGLM_WL_t2_hm_justgotbetter_explore_012009 -------------- next part -------------- An HTML attachment was scrubbed...

If I hadn't my beloved amp wouldn't be sitting where it is today... -------------- Original message from Mark Exstedt : -------------- I am once asking the Naktalk group for help in contacting Scott Johnson. He's had my ZX-7 (A124 14038) for the last 22 months. My last posting on this problem was last summer when I asked the Naktalk group for help to get my deck back. I paid $400 for it, so I'm not talking about some cheaper 2 head Nak which we know can go for under $50. Scott stated in an email to me June 30th that he'll get the deck out that week. Since then I have not heard from him. I sent a certified letter (signature returned) to him in November simply stating to send the deck back, but no luck. I also sent him three emails a few weeks ago stating that I'll be driving thru the L.A. area and I could pick up the deck, but again no response. The Naktalk group tried to help me last time. One gentleman even made searches for phone number contacts. Once again, I feel someone in this group has his phone number, since there's techs and other guys in contact sharing info in fixing equipment. Please, if anyone can help. - Mark Exstedt 602-243-4118 (United States) The following is where this subject left off last summer: This is Scott's comments on my tape deck. Please also look up the link to which he posted: Your ZX-7 was damaged during shipping that I didn't realize until later. It was a small crack on around one of the mounting screws for one of the circuit boards. I repaired the broken traces, but, have not figured out how to secure the board well enough to survive shipping.

If the screw hole was weakened, the PCB can be mounted with two fiber washers, below and above the PCB, resulting, again, in stronger than original mounting. Also, the deck can be packed with internal hard foam bracing to that PCB section. So, claiming the deck won't survive another shipping smacks of dishonesty. No responses since last June isn't acceptable, either. I feel you will be justified in taking more aggressive means. As to recovering the deck... I am a bit confused here. You must have shipped the deck to Scott and therefore, have his address. Since you were in that area anyway, why didn't you drive there to personally see whether he was still in than address, and, if not, whether anyone there (maybe, current resident) had a forwarding address.

I can give the fraud line a try. Now to answer your questions - Scott is still at his present address. The certified letter went to the same address I sent the deck 22 months ago. I believe his wife signed it, since the last name was 'Johnson'. I drove thru L.A. on a 4 day prior notice. My youngest son, age 18, gave me a call and decided to live with me. Driving thru Pasadena in Friday rush hour traffic, Scott's location was some 46-54 miles out of the way. On the way back Saturday, I was driving thru Pasadena at 5 am. I left Phoenix Fri. at 1 pm for Bakersfield and was back at 1:30 pm the next day, doing a 980 mile round trip with a load up. I got laid off from my job last year, so I presently don't have any vacation days to use, otherwise I could have arranged to at least drive to Scott's location and 'hopefully' meet with him.

Unfortunate. I feel for you Mark. Regarding local LA law enforcement, or for that matter any other agency in the USA, they would take the complaint and literally sit on it because they claim," the department does not have sufficient resources to spend on this case because of the low money factor". In fact, in New York's Nassau county I am still awaiting an arrest of my ex-employee who stole over $10000 from my business( cash), which I complained to the department in October 2008, with video evidence of the theft covering at least 50 instances! When the PD  detective assigned to the case is called, we are told" We are working and investigating it and can not provide a ball by ball of the progress." Such is the state of affairs now a days.

I paid $400 for it, so I'm not talking about some cheaper 2 head Nak which we know can go for under $50. Scott stated in an email to me June 30th that he'll get the deck out that week. Since then I have not heard from him. I sent a certified letter (signature returned) to him in November simply stating to send the deck back, but no luck. I also sent him three emails a few weeks ago stating that I'll be driving thru the L.A. area and I could pick up the deck, but again no response. The Naktalk group tried to help me last time. One gentleman even made searches for phone number contacts. Once again, I feel someone in this group has his phone number, since there's techs and other guys in contact sharing info in fixing equipment. Please, if anyone can help. - Mark Exstedt 602-243-4118 (United States) The following is where this subject left off last summer:   This is Scott's comments on my tape deck. Please also look up the link to which he posted:   Your ZX-7 was damaged during shipping that I didn't realize until later.  It was a small crack on around one of the mounting screws for one of the circuit boards.  I repaired the broken traces, but, have not figured out how to secure the board well enough to survive shipping.  I have taken a picture and posted it on the web.   http://www.nakremotes.com/nakremotes/Images/Mark_ZX-7/Mark_ZX-7.htm       Windows Live™ Hotmail®:…more than just e-mail.

Thats almost 2 full years Tom!Nothing in my opinion should take 2 years to fix! Period. The technician should admit defeat and return the deck immediately upon beig stumped by it. What While these repairs do take time, given the size of this single sided boards traces, patching it ought to be straightforward.   Also, I have a ZX7 mechanism logic board here somewhere I purchased on eBay. tom brucker--------------------------------------------========= -------------- next part -------------- An HTML attachment was scrubbed...

You keep the 670zx (good choice) Then i would give away both 481z and 580 to those friend that want to do live recording. Both CD1 and BX300E don't have microphone inputs, so one of them has to go to a friend who doesn't do live recording... give him (or her) the BX300E and keep the CD1 because of it's playback azimuth that may come in handy for you.

We don't even know what use you put the decks to. But, I'll bite, anyway. I assume you use the deck as a source component, with occasional recording of line level signals, and that sound quality is of prime importance. If so, I would keep the 670ZX or the BX-300, since I feel that either sounds better that the 481z and (at least, to me) 3 heads deck are a #1 requirement for the best recording results, which rules out the 580. As to the CD1, I don't know much about it and don't clearly recall how it sounds.

But I realized that the cam gear rotates just a little bit (may be a few degres) when I switch from RR/REWIND to PLAY or from STOP to PLAY positions. But when I go through the service manual, page 12, I understand that when switching from FF to PLAY, the cam gear is supposed to rotate by an angle close to 180° where switching from STOP to FF or REWIND requires only a small rotation.That makes me thonk that the problem comes fron the cam control system. Apparently, the cam motor rotates properly Is it due to a poor cam belt? what else could it be?

Then I put back the cassette in, it works (reverse) properly again for 4 or 5 times and so on... It behaves jsut as it was not able to keep the tuned positions obtained with the connector plugged out. That makes me think to one point: Has the tuning procedure via VR606/VR 607 and VR605 to be performed WITH or WITHOUT a cassette in it?

I have an MR-1 that I finally got around to changing the belts on, but that seemed to have minimal effect on the original problem (stopping around halfway through the tape).  It did play a different tape all the way through, but I think that tape is just more loosely reeled.  I'm guessing what I have is a bad reel motor.  What is the next step from here?  Can you get new reel motors?  (By the way, my MR-1 has the gear update if that changes anything).  Thank you, Jesse --- On Wed, 7/1/09, Ron wrote: From: Ron Subject: Re: Fw: [naktalk] NAK MR-1 #4 NEEDS I-TIRE, LED VU METERS NO WORKEE.

YMMV. on the advice of guys at tapeheads.net, i opened machine, placed paper towels directly under reel motor work area to stop drips onto the belt and other parts. then i very carefully pried back the rear cover of the reel motor, cut one end of the straw that came with deoxit at a very sharp angle, inserted sharp end of straw into the slots in back of reel motor (other end of straw onto deoxit spray hole). then squirted goodly amounts in the 2 slots i could access. let sit for a few moments, then ff and then rw an entire c90. then try playing a tape. that was ~3 weeks ago or so. still running strong. other folks decks are up to a year and still counting having used same procedure. worth a 'shot', imo. and good luck. --- On Wed, 7/1/09, Kenneth Hu wrote: From: Kenneth Hu Subject: [naktalk] BX-300 won't play To: naktalk at naks.com Date: Wednesday, July 1, 2009, 7:56 PM Hi, I got a BX-300 last week.  I cleaned the heads, capstans, pressure rollers with S-721H and replaced the idler tire since ff and rew worked intermittently.  It plays well for a couple of days and now it quits playing after a few seconds.  I notice the tape was pulled out excessively by the right capstan/roller when it stops.  What can be the issue?

That should consistently happen at less than two volts. If it requires a higher voltage, the motor is suspect. You can try squirting contact cleaner into the rear (remove the insulator sheet if there is one), trying to get enough onto the commutator inside. This may solve the problem (or not). People have reported success with this, Personally, I have never been so lucky. If the above doesn't work, the next step requires removing the motor, which is a tedious -- but doable -- job, and rebuilding it. This involves opening it up and manually cleaning the brushes and commutator. The latter should be made shiny and very smooth. I do it by grabbing the rotor shaft in a drill and applying #0000 steel wool while slowly rotating. Then,. lubricate bearings with thin machine oil, apply contact cleaner/lubricant to commutator and reassemble. This solves the problem sometimes, but not always. If none of the above worked. Replace the motor. There is no reliable source for a new motor that I know of. ESL may have it, but may charge more than the cost of the deck. Call Jeff and find out. Or, you may be able to find a parts deck with a good reel motor for reasonable price. Any BX or CR series deck will do. Check ebay and/or local thrift shops. Also, I can sell you a NOS motor that will do the job, for very little.It's not an exact replacement and there are two caveats. First, the mounting holes distance is not the same, so they need to be enlarged, meaning that installation is not that easy. Second, the motor is slightly smaller, so FF/REW times will increase somewhat. I have installed this motor, with excellent result.

BTW, my own CR-7, manufactured in 1985, got the gear upgrade as soon as it came out.

When it happens, I remove the tape and (like you said) close the door, hit play and everything works. The take-up spool is turning. But, once I put the tape back, it stays in play about 2 seconds and stop. FF and rew works fine too. It has been rainy and humid for the past two weeks, could it make the tape too "sticky"?

YMMV. on the advice of guys at tapeheads.net, i opened machine, placed paper towels directly under reel motor work area to stop drips onto the belt and other parts. then i very carefully pried back the rear cover of the reel motor, cut one end of the straw that came with deoxit at a very sharp angle, inserted sharp end of straw into the slots in back of reel motor (other end of straw onto deoxit spray hole). then squirted goodly amounts in the 2 slots i could access. let sit for a few moments, then ff and then rw an entire c90. then try playing a tape. that was ~3 weeks ago or so. still running strong. other folks decks are up to a year and still counting having used same procedure. worth a 'shot', imo. and good luck. --- On Wed, 7/1/09, Kenneth Hu wrote: From: Kenneth Hu Subject: [naktalk] BX-300 won't play To: naktalk at naks.com Date: Wednesday, July 1, 2009, 7:56 PM Hi, I got a BX-300 last week.  I cleaned the heads, capstans, pressure rollers with S-721H and replaced the idler tire since ff and rew worked intermittently.  It plays well for a couple of days and now it quits playing after a few seconds.  I notice the tape was pulled out excessively by the right capstan/roller when it stops.  What can be the issue?

To: Talk about Nakamichi Cassette Decks Message-ID: <4A4CC126.1030504 at verizon.net> Content-Type: text/plain; charset="iso-8859-1" Jesse, To test a reel motor, disconnect a lead, then power it externally from an adjustable power supply, *slowly* increasing the voltage until it just start to turn. That should consistently happen at less than two volts. If it requires a higher voltage, the motor is suspect. You can try squirting contact cleaner into the rear (remove the insulator sheet if there is one), trying to get enough onto the commutator inside. This may solve the problem (or not). People have reported success with this, Personally, I have never been so lucky. If the above doesn't work, the next step requires removing the motor, which is a tedious -- but doable -- job, and rebuilding it. This involves opening it up and manually cleaning the brushes and commutator. The latter should be made shiny and very smooth. I do it by grabbing the rotor shaft in a drill and applying #0000 steel wool while slowly rotating. Then,. lubricate bearings with thin machine oil, apply contact cleaner/lubricant to commutator and reassemble. This solves the problem sometimes, but not always. If none of the above worked. Replace the motor. There is no reliable source for a new motor that I know of. ESL may have it, but may charge more than the cost of the deck. Call Jeff and find out. Or, you may be able to find a parts deck with a good reel motor for reasonable price. Any BX or CR series deck will do. Check ebay and/or local thrift shops. Also, I can sell you a NOS motor that will do the job, for very little.It's not an exact replacement and there are two caveats. First, the mounting holes distance is not the same, so they need to be enlarged, meaning that installation is not that easy. Second, the motor is slightly smaller, so FF/REW times will increase somewhat. I have installed this motor, with excellent result.

What we've observed is the motor will intermittently stop 2/3rds of the way through the tape. Instant stop could be a stalled reel motor, or slipping idler tire.

OTOH, I am curious why Tom thinks a gear idler is harder on the motor than the rubber one. Perhaps he'd like to elaborate? BTW, my own CR-7, manufactured in 1985, got the gear upgrade as soon as it came out. Never gave me any takeup problem whatsoever. -- Ron jayson levitz wrote: > Hi Tom: > > If this is true, it might be because the torque has to be adjusted > once you upgrade to gear drive from tire.

But, once I put the tape back, it stays in play about 2 seconds and stop. FF and rew works fine too. It has been rainy and humid for the past two weeks, could it make the tape too "sticky"?

YMMV. on the advice of guys at tapeheads.net, i opened machine, placed paper towels directly under reel motor work area to stop drips onto the belt and other parts. then i very carefully pried back the rear cover of the reel motor, cut one end of the straw that came with deoxit at a very sharp angle, inserted sharp end of straw into the slots in back of reel motor (other end of straw onto deoxit spray hole). then squirted goodly amounts in the 2 slots i could access. let sit for a few moments, then ff and then rw an entire c90. then try playing a tape. that was ~3 weeks ago or so. still running strong. other folks decks are up to a year and still counting having used same procedure. worth a 'shot', imo. and good luck. --- On Wed, 7/1/09, Kenneth Hu wrote: From: Kenneth Hu Subject: [naktalk] BX-300 won't play To: naktalk at naks.com Date: Wednesday, July 1, 2009, 7:56 PM Hi, I got a BX-300 last week.  I cleaned the heads, capstans, pressure rollers with S-721H and replaced the idler tire since ff and rew worked intermittently.  It plays well for a couple of days and now it quits playing after a few seconds.  I notice the tape was pulled out excessively by the right capstan/roller when it stops.  What can be the issue?

To: Talk about Nakamichi Cassette Decks Message-ID: <4A4CC126.1030504 at verizon.net> Content-Type: text/plain; charset="iso-8859-1" Jesse, To test a reel motor, disconnect a lead, then power it externally from an adjustable power supply, *slowly* increasing the voltage until it just start to turn. That should consistently happen at less than two volts. If it requires a higher voltage, the motor is suspect. You can try squirting contact cleaner into the rear (remove the insulator sheet if there is one), trying to get enough onto the commutator inside. This may solve the problem (or not). People have reported success with this, Personally, I have never been so lucky. If the above doesn't work, the next step requires removing the motor, which is a tedious -- but doable -- job, and rebuilding it. This involves opening it up and manually cleaning the brushes and commutator. The latter should be made shiny and very smooth. I do it by grabbing the rotor shaft in a drill and applying #0000 steel wool while slowly rotating. Then,. lubricate bearings with thin machine oil, apply contact cleaner/lubricant to commutator and reassemble. This solves the problem sometimes, but not always. If none of the above worked. Replace the motor. There is no reliable source for a new motor that I know of. ESL may have it, but may charge more than the cost of the deck. Call Jeff and find out. Or, you may be able to find a parts deck with a good reel motor for reasonable price. Any BX or CR series deck will do. Check ebay and/or local thrift shops. Also, I can sell you a NOS motor that will do the job, for very little.It's not an exact replacement and there are two caveats. First, the mounting holes distance is not the same, so they need to be enlarged, meaning that installation is not that easy. Second, the motor is slightly smaller, so FF/REW times will increase somewhat. I have installed this motor, with excellent result.

What we've observed is the motor will intermittently stop 2/3rds of the way through the tape. Instant stop could be a stalled reel motor, or slipping idler tire. Some substitute tires are not large enough in diameter to make complete contact during play. tom brucker -----Original Message----- From: naktalk-bounces at naks.com [mailto:naktalk-bounces at naks.com]On Behalf Of Kenneth Hu Sent: Thursday, July 02, 2009 7:17 AM To: Talk about Nakamichi Cassette Decks Subject: Re: [naktalk] BX-300 won't play The behavior seems to be intermittent.

OTOH, I am curious why Tom thinks a gear idler is harder on the motor than the rubber one. Perhaps he'd like to elaborate? BTW, my own CR-7, manufactured in 1985, got the gear upgrade as soon as it came out. Never gave me any takeup problem whatsoever. -- Ron jayson levitz wrote: > Hi Tom: > > If this is true, it might be because the torque has to be adjusted > once you upgrade to gear drive from tire.

YMMV. on the advice of guys at tapeheads.net, i opened machine, placed paper towels directly under reel motor work area to stop drips onto the belt and other parts. then i very carefully pried back the rear cover of the reel motor, cut one end of the straw that came with deoxit at a very sharp angle, inserted sharp end of straw into the slots in back of reel motor (other end of straw onto deoxit spray hole). then squirted goodly amounts in the 2 slots i could access. let sit for a few moments, then ff and then rw an entire c90. then try playing a tape. that was ~3 weeks ago or so. still running strong. other folks decks are up to a year and still counting having used same procedure. worth a 'shot', imo. and good luck. --- On Wed, 7/1/09, Kenneth Hu wrote: From: Kenneth Hu Subject: [naktalk] BX-300 won't play To: naktalk at naks.com Date: Wednesday, July 1, 2009, 7:56 PM Hi, I got a BX-300 last week.  I cleaned the heads, capstans, pressure rollers with S-721H and replaced the idler tire since ff and rew worked intermittently.  It plays well for a couple of days and now it quits playing after a few seconds.  I notice the tape was pulled out excessively by the right capstan/roller when it stops.  What can be the issue?

To: Talk about Nakamichi Cassette Decks Message-ID: <4A4CC126.1030504 at verizon.net> Content-Type: text/plain; charset="iso-8859-1" Jesse, To test a reel motor, disconnect a lead, then power it externally from an adjustable power supply, *slowly* increasing the voltage until it just start to turn. That should consistently happen at less than two volts. If it requires a higher voltage, the motor is suspect. You can try squirting contact cleaner into the rear (remove the insulator sheet if there is one), trying to get enough onto the commutator inside. This may solve the problem (or not). People have reported success with this, Personally, I have never been so lucky. If the above doesn't work, the next step requires removing the motor, which is a tedious -- but doable -- job, and rebuilding it. This involves opening it up and manually cleaning the brushes and commutator. The latter should be made shiny and very smooth. I do it by grabbing the rotor shaft in a drill and applying #0000 steel wool while slowly rotating. Then,. lubricate bearings with thin machine oil, apply contact cleaner/lubricant to commutator and reassemble. This solves the problem sometimes, but not always. If none of the above worked. Replace the motor. There is no reliable source for a new motor that I know of. ESL may have it, but may charge more than the cost of the deck. Call Jeff and find out. Or, you may be able to find a parts deck with a good reel motor for reasonable price. Any BX or CR series deck will do. Check ebay and/or local thrift shops. Also, I can sell you a NOS motor that will do the job, for very little.It's not an exact replacement and there are two caveats. First, the mounting holes distance is not the same, so they need to be enlarged, meaning that installation is not that easy. Second, the motor is slightly smaller, so FF/REW times will increase somewhat. I have installed this motor, with excellent result.

If this is not there you need a service tech right away! You may choose to open the deck up and reseat all the four boards to the right of the unit.( rec eq,record dolby, detector and play dolby) Good luck.At times this solves issues!  Clean the three heads thoroughly first and then demagnetize with Han D Mag. Check if the Playback is correct. Also check if you can adjust just the azimuth without autocalibration. If the deck fails this you need a tech.  Try the calibration again if you succeed with azimuth first. Please make sure that the bias fine tune is pointing  dead north.  Try a different tape brand like TDK or Maxell. Check if the deck calibrates this one. If these preliminary steps fail, a visit to a qualified tech is a must. However, please note that some Sony's( from the early 70s' are difficult to calibrate on the ZXL but will do fine on otehr decks. If you must need service, Kannan, Willy and ESL are your best bets in the USA.

Clean heads, tape travel path and fully demagnetize heads. 2. A good quality tape 3. Is the azimuth alignment being done fast and proper? 4. If the answer is yes to item 3, then you probably need to get the deck serviced         especially the electronic calibration of the computing section. 5. Chances are high that your deck probably needs a total re-alignment of electronics and     tape path mechanics. Has the deck been calibrating properly previously, and have you been having any orange capacitor problems with the deck? Best Regards Bala The best in this case would be to get an experienced service person like ESL Labs to get the deck fully working. --- On Fri, 7/3/09, cmpsalvestrini at gmail.com wrote: From: cmpsalvestrini at gmail.com Subject: [naktalk] Erratic calibration on ZXL1000 To: naktalk at naks.com Date: Friday, July 3, 2009, 8:58 PM Hello all, I've noticed that my deck, a ZXL1000,  behaves erratically when calibrating, it takes a long time to calibrate a normal position tape, a Sony HF-60 (counter goes to approximately 140) and on a second run on the B-side of the same tape the calibration doesn't run at all, counter got to approximately 205 before I interrupted the calibration run). Ideas / suggestions for diagnostics? Thank you in advance.

YMMV. on the advice of guys at tapeheads.net, i opened machine, placed paper towels directly under reel motor work area to stop drips onto the belt and other parts. then i very carefully pried back the rear cover of the reel motor, cut one end of the straw that came with deoxit at a very sharp angle, inserted sharp end of straw into the slots in back of reel motor (other end of straw onto deoxit spray hole). then squirted goodly amounts in the 2 slots i could access. let sit for a few moments, then ff and then rw an entire c90. then try playing a tape. that was ~3 weeks ago or so. still running strong. other folks decks are up to a year and still counting having used same procedure. worth a 'shot', imo. and good luck. --- On Wed, 7/1/09, Kenneth Hu wrote: From: Kenneth Hu Subject: [naktalk] BX-300 won't play To: naktalk at naks.com Date: Wednesday, July 1, 2009, 7:56 PM Hi, I got a BX-300 last week.  I cleaned the heads, capstans, pressure rollers with S-721H and replaced the idler tire since ff and rew worked intermittently.  It plays well for a couple of days and now it quits playing after a few seconds.  I notice the tape was pulled out excessively by the right capstan/roller when it stops.  What can be the issue?

To: Talk about Nakamichi Cassette Decks Message-ID: <4A4CC126.1030504 at verizon.net> Content-Type: text/plain; charset="iso-8859-1" Jesse, To test a reel motor, disconnect a lead, then power it externally from an adjustable power supply, *slowly* increasing the voltage until it just start to turn. That should consistently happen at less than two volts. If it requires a higher voltage, the motor is suspect. You can try squirting contact cleaner into the rear (remove the insulator sheet if there is one), trying to get enough onto the commutator inside. This may solve the problem (or not). People have reported success with this, Personally, I have never been so lucky. If the above doesn't work, the next step requires removing the motor, which is a tedious -- but doable -- job, and rebuilding it. This involves opening it up and manually cleaning the brushes and commutator. The latter should be made shiny and very smooth. I do it by grabbing the rotor shaft in a drill and applying #0000 steel wool while slowly rotating. Then,. lubricate bearings with thin machine oil, apply contact cleaner/lubricant to commutator and reassemble. This solves the problem sometimes, but not always. If none of the above worked. Replace the motor. There is no reliable source for a new motor that I know of. ESL may have it, but may charge more than the cost of the deck. Call Jeff and find out. Or, you may be able to find a parts deck with a good reel motor for reasonable price. Any BX or CR series deck will do. Check ebay and/or local thrift shops. Also, I can sell you a NOS motor that will do the job, for very little.It's not an exact replacement and there are two caveats. First, the mounting holes distance is not the same, so they need to be enlarged, meaning that installation is not that easy. Second, the motor is slightly smaller, so FF/REW times will increase somewhat. I have installed this motor, with excellent result.

OTOH, I am curious why Tom thinks a gear idler is harder on the motor than the rubber one. Perhaps he'd like to elaborate? BTW, my own CR-7, manufactured in 1985, got the gear upgrade as soon as it came out.

Does it always easily and quickly get through the azimuth section? If not pull the auto azimuth box and thoroughly clean the threads. Make sure the belt isn't too tight and that the unit moves with less that three volts (ideally 1.5 volts). If the azimuth is good go through the entire set up procedure in the manual. This requires the test set. The 1000ZXL I just sent back to RAM calibrates in an amazingly short amount of time since I calibrated all settings as carefully as I could. Good luck -- the set up procedure takes a long time!

Good luck -- the set up procedure takes a long time! Willy Willy == -------------- next part -------------- An HTML attachment was scrubbed...

I'm working on a friend's CR-7A that has the counter go crazy after a few minutes and then disappear. IC606 seems pretty hot. When I cool that chip the counter pops back to normal for a few more minutes. I've already checked for cold solder joints. He had someone in California work on it two years ago. The wiring is pretty messy in it and it's missing the Logic PCB hinges! It's disappointing to see a nice deck messed up in a service shop. The wow and flutter is also out of spec presently but I haven't dissected the mechanism yet. Seems like I saw a posting about a CR-7 with missing PCB hinges and a bad capstan motor a while ago. Interesting. P.S. Is there any way to search the Archives?

Is this Vcc supply clean ?   Does IC 606 get hot when the unit is on and no functions invoked ? If so, allow the chip to cool down to ambient again. With the CR 7 off unplug the data and segment lines, connectors CN 14 and CN 15 respectively from the logic board. Turn the unit on and idle. Do this heat test again. If IC606 is still drawing excessive current Turn the power back off and allow the power supply to naturally discharge.   With CN 14 and CN 15 plugged back in at this time make a list of the resistance readings  of all 42 pins of upc 606 with respect to ground and forward them to me. I will compare them to readings taken on my bench CR 7. Given the description of the wiring condition you mentioned, there may be a pinched wire at the display board mounting or in that front panel location somewhere.

Also, check the IC power supply. If the voltages are high, more power would be consumed. Lowering the power supply (s) might reduce the heating.

Message-ID: <67D72D385E3847B18349401A78658D3F@fujitsu> Hello everyone! Just found out about this list. I am a Nak lover and have several subjects to discuss. 1- I have a pile of Nak MR-1 and MR-2 decks for parts if anyone can use them. Unfortunately they are all partially disassembled. A local repair shop went out of Biz and I cleaned out there back room and this pile was sitting there so I grabbed them. Please email me if anyone can use these or needs specific parts. overkill@@@mindspring.com 2- I am looking for a LC75384NE-R or 75410E Digital Volume controller IC from a TD-35/45Z or CD-35/45Z or MD-35/45Z car stereo. Or dead units, or circuit boards etc. or anyone that can source one of these IC's for me. I have googled and Binged and Yahoo'ed and no luck. 3- I am desperately trying to find any sort of information RE: the Nakamichi CD Changer control protocol used in most of there decks with the 13 PIN din connector. I have the pin out of the connector. But I can find zero information on the protocol. I have discovered by sheer luck that old old sony CD changers with the 13p connector work, and I have heard that old Denon and Eclipse/Fujitsu Ten changers work as well. I am 1/4 step away from hiring some bit bangers to reverse the protocol for me. But it would be much easier to find someone with at least any part of the info. This is a long shot but you never know. 4- I am looking for info on the newer CD300/400/500 car stereo's. Only the 500 is listed as being a changer controller. But no information on what protocol it uses. Is it the old Nak 13P or is it compatible with one of the newer or more standard formats like unilink, Ai-Net, M-Bus. I have owned many Naks over the years. Letting go of my 680ZX was really hard to do. I have also had TD-500, I currently own and use the TD-45Z and MF-51 changer in my car and I have a TD-35Z on my bench waiting for the above mentioned IC. I might be getting another TD-500 later today if things go as planned as well. I have done extensive research into the Nak TD series decks and there inner workings. I have a mod for the bass control that moves it down from 100hz to a more usable 50hz and also changes it from a peaking filter to a shelving filter. Which it really should have been in the first place. So Hello, I know that was a lot to throw out there but sometimes when you find water you need to bring a big bucket!

I got a chance to dive into the CR-7 last night. My friend mentioned that he had taken the unit for service in California two years ago for a power supply repair and the counter started acting up after that. Well, the missing logic board hinges and the missing wiring harness cable ties were an indication of the quality of that service tech. I checked the power supply and the 5.6v supply was so high that I am shocked that it didn't fry all of the micro processors on the logic board!! 8~O I replaced the 6.2 volt zener and cleaned up the sloppy "repair" work. i.e. wrong value fuse resistors tacked onto the backside of the PS PCB. Once all of the supplies were to spec the machine is happy again! After lubing the capstan bearings the W & F dropped to 1/10th the first reading. Now it just needs Fred's belt kit and my friend will have a nice CR-7A back in his system! Thanks again!

I got a chance to dive into the CR-7 last night. My friend mentioned that he had taken the unit for service in California two years ago for a power supply repair and the counter started acting up after that. Well, the missing logic board hinges and the missing wiring harness cable ties were an indication of the quality of that service tech. I checked the power supply and the 5.6v supply was so high that I am shocked that it didn't fry all of the micro processors on the logic board!! 8~O I replaced the 6.2 volt zener and cleaned up the sloppy "repair" work. i.e. wrong value fuse resistors tacked onto the backside of the PS PCB. Once all of the supplies were to spec the machine is happy again! After lubing the capstan bearings the W & F dropped to 1/10th the first reading. Now it just needs Fred's belt kit and my friend will have a nice CR-7A back in his system! Thanks again!

And when I saw that pile of decks sitting there I just knew I would find people that could use those! It took me a while to get a message through to the list. I signed up with my normal email account and it wouldn't let me post to the list. I have an EarthLink account and the messages kept bouncing after 24-48 hours. But this gmail account seems to be working :) I have learned quite a bit about the nak car decks since I found this list. The TD series is based on Sony decks I discovered. Someone else mentioned this to me and I have found many many similarities. I'm kind of disappointed in that frankly but I do still love my TD-45Z/MF-51 setup. What I have learned about the Nak CDC Protocol is that they use 2 separate serial strings to talk to and from the CD changer. No one else does this. They use one set of Clock & Data lines to send commands to the changer and another set of Clock & Data lines for the changer to send back what I suspect is time information. I am getting together with some people to examine the buss and figure out the protocol this weekend. At least get the basics of the protocol figured out. Then I will have to spend some time with a logic analyzer to decode all of the commands. My hope is to build several types of devices for the Nak decks. One of which is some form of CD changer adapter to convert the Nak buss to some other protocol. Like M-Buss or Ai-Net or Uni-link etc. so that newer changers can be used. Possibly changers with MP3 playback capabilities. I have also done much research into the TD series Digital volume controller IC. One of the things that has always bugged me about the deck is that the bass control. Isn't really a bass control. It is centered at 100hz and is a band pass control not a shelving control. I have cracked that mystery and know how to changer the center frequency and how to easily convert it to a shelving control. I am experimenting a bit with that now. Anyway. Stay tuned. I will be back LOL!

In-Reply-To: Message-ID: <8B07709493F04E08886D5CF27C8E94B7@fujitsu> Tom, No nak car stereo I have ever seen has had uni-link on it! The new CD-500 would have uni-link if they had ever converted. And it is odd that they never have Which I find interesting. I wish I could get my hands on a CD-500 and do some testing. I am curious to see if they implemented any changes in the protocol at all? but at $1500 its way way out of my price range. And none of the lower line units, the CD-300 or 400 have the changer control. I have done some work in the past reverse engineering protocols. My company did a bit of work for the newer Mazda car stereo's where we designed an aux input interface and we actually got it to work, have a half dozen prototypes working but we ran into some issues sourcing the mazda radio connector needed. And by the time we sorted that out we were so late to market that the competition had us beat anyway so we just folded the project. There is quite a bit of information on the web about uni-link and other protocols from the car-PC guys, the guys that build there own carputers, and they have documented quite a bit of the uni-link protocol. It's a bit more complex then the Nak protocol. So first I need to document the Nak stuff, then I will be playing with M-Buss which is what the mazda's used as well as older alpine and a bazillion other brands, which is easy, and then the Uni-Link stuff. And I am really curious to see how similar in word structure the nak and Uni-link are. Being both sourced from Sony, There has to be some common language I would expect. Or at least some common root anyway. This will be fun and interesting.

Both the units( the one with the meters active and not) calibrate perfect. However I was just told by another knowledgeable individual that may be the mute circuit was allowing the tones to be displayed due to capacitor /resistor leakage needing a fix on the unit that displays it. In fact I am taking a liking to the CR7 now after many years of nakking. I guess I finally landed a great  CR7 after 4 so so ones...!

There is no display activity during tape calibration. What's more, if the deck is set for source monitoring (display showing source signal) and Calibrate is pressed, the display blanks during the calibration and comes on when it's done. I'm too lazy to check the schematic for what the deck is supposed  to do. If this function is controlled by the uP, it is possible that there are two different versions out there. -- Ron shanti ramachandran wrote: Hi folks, Does the Cr-7, while calibrating a tape, typically have anything on the meters( level signals, I mean) displayed? If so, were there production runs where this display is not there while calibrating and some runs where there was a display during the process. I ask this because I have seen one with and one without this phenomenon. Just intrigued about this feature. Thanks.

There have been many high-profile artists and groups that have had drug and alcohol problems (turning vegetarian doesn't undo things) but that doesn't stop people from accepting their good music. The guy is gone, and while he was around he gave people lots of good music.

Please remember that he was formally acquitted of all  child abuse charges filed against him in a US court of law, by a jury of his peers. That in the USA means, he did not commit the crime and is INNOCENT. He might have had drug issues and this is a common ailment of most celebrities, if not all, although it should not be, but that's their personal lives. Mr. Michael Jackson was one of the most brilliant performers of all times and he has given me and many others' many hours of listening and viewing pleasure unlike any other artist in the past 38 years or so. To ignore  this talent that is unsurpassed in its class,  is to deny his art by polluting it with his misgivings. He was one of the greatest performers and philanthropists ( yes he donated more to children's' charities than many we know) the world has ever had. Marc, there is no human with misgivings and problems. We need to be tolerant as long as they do not effect us directly. He is now dead and can not defend himself and we should respect that. The world will miss Mr. Jackson and his talent for many many eons to come. Thanks. Ram Thank you Mr. Jackson for  all the wonderful music you made!

I got a chance to dive into the CR-7 last night. My friend mentioned that he had taken the unit for service in California two years ago for a power supply repair and the counter started acting up after that. Well, the missing logic board hinges and the missing wiring harness cable ties were an indication of the quality of that service tech. I checked the power supply and the 5.6v supply was so high that I am shocked that it didn't fry all of the micro processors on the logic board!! 8~O I replaced the 6.2 volt zener and cleaned up the sloppy "repair" work. i.e. wrong value fuse resistors tacked onto the backside of the PS PCB. Once all of the supplies were to spec the machine is happy again! After lubing the capstan bearings the W & F dropped to 1/10th the first reading. Now it just needs Fred's belt kit and my friend will have a nice CR-7A back in his system! Thanks again!

Is this Vcc supply clean ? Does IC 606 get hot when the unit is on and no functions invoked ? If so, allow the chip to cool down to ambient again. With the CR 7 off unplug the data and segment lines, connectors CN 14 and CN 15 respectively from the logic board. Turn the unit on and idle. Do this heat test again. If IC606 is still drawing excessive current Turn the power back off and allow the power supply to naturally discharge. With CN 14 and CN 15 plugged back in at this time make a list of the resistance readings of all 42 pins of upc 606 with respect to ground and forward them to me. I will compare them to readings taken on my bench CR 7. Given the description of the wiring condition you mentioned, there may be a pinched wire at the display board mounting or in that front panel location somewhere. Be sure all the interconnections to the display board area are free and not pinched under mountings, etc. I can test the chip for you if you want to take the care and effort to desolder it and forward it to me in NH somewhere down the road.

I'm working on a friend's CR-7A that has the counter go crazy after a few minutes and then disappear. IC606 seems pretty hot. When I cool that chip the counter pops back to normal for a few more minutes. I've already checked for cold solder joints. He had someone in California work on it two years ago. The wiring is pretty messy in it and it's missing the Logic PCB hinges! It's disappointing to see a nice deck messed up in a service shop. The wow and flutter is also out of spec presently but I haven't dissected the mechanism yet. Seems like I saw a posting about a CR-7 with missing PCB hinges and a bad capstan motor a while ago. Interesting. P.S. Is there any way to search the Archives?

URL: From iowa_hawk1 at yahoo.com Fri Jul 10 17:32:33 2009 From: iowa_hawk1 at yahoo.com (Larry Sachs) Date: Fri, 10 Jul 2009 08:32:33 -0700 (PDT) Subject: [naktalk] Micahel Jackson Message-ID: <807146.21290.qm@web84107.mail.mud.yahoo.com> Shanti,   I agree with almost everything you said except: "...that he was formally acquitted of all child abuse charges filed against him in a US court of law, by a jury of his peers. That in the USA means, he did not commit the crime and is INNOCENT."   As an Assistant District Attorney in the United States I can say without reservation that the verdict rendered by the jury is not "innocent," nor does it mean that he did not commit the crimes charged. The jury in his case found him "not guilty" on each of the counts with which he was charged. That means that the State of California was unable to convince all twelve of the jurors beyond a reasonable doubt that he did it.  However, the alleged victim could still have sued him in civil court and won a verdict against him despite his acquittal in criminal court because the standard of proof in civil court is only "by a preponderance of the evidence" and because civil juries are not required to be unanimous.   Please do not take the above to mean that I think he did do it, it was merely my discourse on the law. I wasn't in the courtroom and didn't hear the evidence so I offer no opinion on whether he did it.   That being said, he was a consumate entertainer despite being a pretty screwed up individual. His talent will rightfully be missed by anyone who appreciates music and dance.   Larry --- On Fri, 7/10/09, shanti ramachandran wrote: From: shanti ramachandran Subject: Re: [naktalk] Micahel Jackson To: "Talk about Nakamichi Cassette Decks" Date: Friday, July 10, 2009, 9:17 AM Marc, I beg to radically differ from your esteemed opinion on Michael Jackson. Please remember that he was formally acquitted of all  child abuse charges filed against him in a US court of law, by a jury of his peers. That in the USA means, he did not commit the crime and is INNOCENT. He might have had drug issues and this is a common ailment of most celebrities, if not all, although it should not be, but that's their personal lives. Mr. Michael Jackson was one of the most brilliant performers of all times and he has given me and many others' many hours of listening and viewing pleasure unlike any other artist in the past 38 years or so. To ignore  this talent that is unsurpassed in its class,  is to deny his art by polluting it with his misgivings. He was one of the greatest performers and philanthropists ( yes he donated more to children's' charities than many we know) the world has ever had. Marc, there is no human with misgivings and problems. We need to be tolerant as long as they do not effect us directly. He is now dead and can not defend himself and we should respect that. The world will miss Mr. Jackson and his talent for many many eons to come. Thanks. Ram Thank you Mr. Jackson for  all the wonderful music you made!

I suspect, as well, that its low frequency response would be sadly deficient, and golden-eared aficionados would fault it for a strange squeakiness in the highs. Ah, but unlike so much intimidatingly-complex high-end gear of the Nakamichi stripe, this one was entirely child-friendly. Well, s---, dear readers, that's what happens when someone who cut his Pop music teeth on the likes of Sinatra, Ella, and Vic Damone, adds his curmudgeonly-suspect views to such things.

I am disappointed that some members here are just too ready to beat a dead horse - the guy is gone and the least we can do is remember him for what he left behind.

It's designed to set the transport to the STOP mode at the end of tape, by sensing when the tape no longer moves. Any fault that prevents normal tape traveling will trigger the STOP mode, which is exactly what the tape sensor is supposed to do. The tape sensor consists of a disk that rotates while the tape is in motion. It has black radial lines, alternating with transparent lines. A light and photo transistor 'read' these lines and produce a square wave signal while the tape is in motion. This is fed to a small PCB that, in turn, stops the transport when the square wave disappears. You can find more detailed explanations in the 480 service manual, that you can download from the Naks.com wiki page.

So much of the hardware (except the CSM) has worked perfectly when required despite the state of art. The program has an enduring legacy that is being used as the base design for the Ares return to the moon program. When you mentioned the B&W camera, here is an interesting news. The camera that was built to capture the astronauts doing their stuff on the moon as we all know worked very well. What most people did not know was that the image quality that was seen then and captured for posterity was anything near the real thing. The designers were unable to use the regular broadcast frequencies as these were used to transmit telemetry data. They designed their own broadcast system around another set of frequencies as a workaround. When the moon landing happened, and the designers watched the live broadcast, they were relieved that their cameras worked perfectly in the lunar environment. They simply assumed that the signal deterioration (which was not seen in their tests)  was due to the distance. In a tracking station in Australia, one of the three built to capture the broadcasts, the engineers and technicians saw the moonwalk telecast in perfect visual fidelity however. The version that the world saw was relayed and transmitted all over. It was not until a few years ago that the camera designers themselves saw some pictures taken off the television monitors did they realize that not only did their system work, but it did it's job perfectly. The good news was that the Australian tracking station did record the broadcast on magnetic tape. The tapes were then shipped to the US where they lay in federal storage until the mid 80s. Then the tapes disappeared! There is a massive effort to recover these tapes and hopefully they will be found.

Service Code for TD-1200 If you have a TD-1200 you know that there is a 5 minute wait from the time power is first applied to when you can enter the service code to unlock the deck and start using it. Did you know there is a service code that you can enter that will eliminate the 5 minute wait? You will still need the unlock code however. The service code is 41113. Just enter this code followed by your decks unlock code and it will unlock without waiting 5 minutes. I haven't tried it myself. I got this from someone. First 1 dumb question.

So much of the hardware (except the CSM) has worked perfectly when required despite the state of art. The program has an enduring legacy that is being used as the base design for the Ares return to the moon program. When you mentioned the B&W camera, here is an interesting news. The camera that was built to capture the astronauts doing their stuff on the moon as we all know worked very well. What most people did not know was that the image quality that was seen then and captured for posterity was anything near the real thing. The designers were unable to use the regular broadcast frequencies as these were used to transmit telemetry data. They designed their own broadcast system around another set of frequencies as a workaround. When the moon landing happened, and the designers watched the live broadcast, they were relieved that their cameras worked perfectly in the lunar environment. They simply assumed that the signal deterioration (which was not seen in their tests) was due to the distance. In a tracking station in Australia, one of the three built to capture the broadcasts, the engineers and technicians saw the moonwalk telecast in perfect visual fidelity however. The version that the world saw was relayed and transmitted all over. It was not until a few years ago that the camera designers themselves saw some pictures taken off the television monitors did they realize that not only did their system work, but it did it's job perfectly. The good news was that the Australian tracking station did record the broadcast on magnetic tape. The tapes were then shipped to the US where they lay in federal storage until the mid 80s. Then the tapes disappeared! There is a massive effort to recover these tapes and hopefully they will be found.

It slips, the tape quits taking up and the sensor stops the transport. The problem is that the replacement of that idler requires splitting the transport which is a tricky job. Yes, it probably will cost more than the deck is worth to fix this problem. As an interim solution, try cleaning the idler with a swab and denatured alcohol or head cleaner. It may make it work for a while. Best of luck.

You may also be able to find a used (but still good) motor from a parts deck. Or maybe find a whole parts deck with a good motor. Keep an eye on this email list or even [shudder] that e-place.

So much of the hardware (except the CSM) has worked perfectly when required despite the state of art. The program has an enduring legacy that is being used as the base design for the Ares return to the moon program. When you mentioned the B&W camera, here is an interesting news. The camera that was built to capture the astronauts doing their stuff on the moon as we all know worked very well. What most people did not know was that the image quality that was seen then and captured for posterity was anything near the real thing. The designers were unable to use the regular broadcast frequencies as these were used to transmit telemetry data. They designed their own broadcast system around another set of frequencies as a workaround. When the moon landing happened, and the designers watched the live broadcast, they were relieved that their cameras worked perfectly in the lunar environment. They simply assumed that the signal deterioration (which was not seen in their tests)  was due to the distance. In a tracking station in Australia, one of the three built to capture the broadcasts, the engineers and technicians saw the moonwalk telecast in perfect visual fidelity however. The version that the world saw was relayed and transmitted all over. It was not until a few years ago that the camera designers themselves saw some pictures taken off the television monitors did they realize that not only did their system work, but it did it's job perfectly. The good news was that the Australian tracking station did record the broadcast on magnetic tape. The tapes were then shipped to the US where they lay in federal storage until the mid 80s. Then the tapes disappeared! There is a massive effort to recover these tapes and hopefully they will be found.

I was visiting my parents, and my mom mentioned that she had a cassette interview of my late uncle, done on July 20, 1969, in between the moon landing and the first moonwalk (at least a decade before Michael Jackson did one). This interview was important to me, because I had been a huge fan of the space program when I was growing my uncle was a vice president at Collins Radio, in charge of building the voice and telemmetry modules for the Apollo project, as well as the b&w TV camera that projected the images that everyone saw for the first time.  The interview is about which items they built and where they fit in to the whole project. So, every time I hear "That's one small step for man, one giant leap for mankind", I think of Uncle Hap. I carefully brought the tape back home in my carry-on bag, and transferred it, first to DAT, and then to the computer.  I decided to use the CR-7, so I could use the azimuth adjustment (since it was a mono tape, this was important and easy to do), and then did the speed adjustment digitally. I shrank it down to an MP3 for most of the cousins and relatives, so it was small enough to be emailed, but I saved the unmodified .WAV file to send to his son-in-law, Lou Giordano, who is a recording engineer; he was very excited to hear of its existence, and will do his magic on it. Ultimately, I expect that we'll upload it to the Internet Archive, since it's a piece of the history of humanity. ========---------------------------------------------------------=========          Also check out the wiki! http://www.naks.com/wiki ========---------------------------------------------------------=========                        Naktalk at naks.com mailinglist Maintain your account here: http://www.naks.com/mailman/listinfo/naktalk ========---------------------------------------------------------========= -----Inline Attachment Follows----- ========---------------------------------------------------------=========           Also check out the wiki! http://www.naks.com/wiki ========---------------------------------------------------------=========                         Naktalk at naks.com mailinglist Maintain your account here: http://www.naks.com/mailman/listinfo/naktalk ========---------------------------------------------------------========= -------------- next part -------------- An HTML attachment was scrubbed...

This makes me think it better to buy a parts unit for it then the other way around as, at least mechanicals aside, mine is pretty original and hard to beat. But if could be good for someone who would like an original box, manual, nice cabinet and faceplate if anyone interested? Damn, it played SOOO good before it died. I feel like I should have a funeral for it. Might try cleaning the idler tire to see if it comes back from the grave. I did talk to the E-people you mentioned. I would have to get a loan! ================================ Ron said: You may be able to salvage the motor by rebuilding. Assuming, of course, that the motor is, indeed, the source of the problem. This, too, has it's cost if you have a professional do it for you. You may also be able to find a used (but still good) motor from a parts deck. Or maybe find a whole parts deck with a good motor. Keep an eye on this email list or even [shudder] that e-place. Alternately, you can sell the deck for parts, though it's probably not worth that much. But at least, it will not go to waste, but help someone to resurrect another 480. -- Ron From williamsunique at yahoo.co.uk Fri Jul 17 09:58:26 2009 From: williamsunique at yahoo.co.uk (paul williams) Date: Fri, 17 Jul 2009 07:58:26 +0000 (GMT) Subject: [naktalk] Original Tapes Re-Recorded / Lost Content / Was Here's what I used my Nak for this Message-ID: <328784.37533.qm@web23008.mail.ird.yahoo.com> Thanks for that.  It does seem strange though that something as important historically should be lost this way.

I am the original owner of a black Nakamichi 480 deck and love it. It is the only to go! Recently the Play (PL602) indicator lamp has burned out. I have downloaded the 480 manual and found a mention of the lamp replacement in a few postings. I have looked at several parts suppliers for a replacement that meets the following: 3mm, radial leads, 24 Vdc, 20 ma, and the closest I find is a nice one in other respects except it is 14 v at 40 ma. The 3mm radial lead lamp is the only one that will slip into the rubber boot on the back of the lamp holder. I can use a dropping resistor (1/2 watt ain't pretty) and run the lamp at about 9 v to get the same brilliance as the Pause lamp. This is not original but I could live with it. I guess I could use a white LED and just get the brightness I get. Then I could just change all three. I checked with Digi-Key, Radio Shack, Parts Express, All Electronics (they had the 14v/40ma). Question: Is this lamp driven with a transistor or the Play push button? If it is transistor driven then I would worry about the 40 ma vs, 20 ma. I cannot tell much by trying to read the fine print on the schematic in the online manual. Please advise, Richard -------------- next part -------------- An HTML attachment was scrubbed...

They have a diffused T1 (3mm) yellow LED, Cat #MLED-4. Yellow may be closer to the original lamp than a white LED. I don't have one on hand, but do have a similar green LED (Cat #MLED-2). Brightness at 10mA is fine. These LEDs are so cheap that the risk in buying 10 and testing them is low. If brightness is sufficient but the color doesn't match exactly, just replace all lamps.

It is in very good shape, but has a problem. The motor engages and then kicks off. No FF or RW. I purchased a new roller wheel and thought I would try that first. I signed up for this list then. Anyway I have never even tryed to do the repair and now I have decided to sell it on Ebay. I am not sure if the roller is the problem or something bigger in the motor. It is in great shape visually, but somehow I misplaced the cover screws so they are gone. Anyway I thought I would ask on here if anyone wants to offer anything for it (at least 60.00) If nobody thinks it is worth $60.00 I will give it a try on Ebay. I can provide as many pictures as anybody would like. Thanks   Keith.Knaggs at yahoo.com -------------- next part -------------- An HTML attachment was scrubbed...

All your symptoms could be caused by the tape not being properly suspended between the two capstans which happens when the belt has stretched far enough to begin to slip. To keep the wow and flutter reasonable try the "gold" belt from marrscommunications.com .

Not only are they extremely hard to find, but -- if and when found -- will cost *substantially* more that the deck is worth. Some can be done without -- for example, the torque gauge. Consider farming out work that requires any of the rest, even if you have to upkeep several 480 decks. You did not include alignment tapes. These are required for head alignment and tend to be a necessity. Fortunately, after-market tapes are available at reasonable cost. For example, see http://naks.es/services.html. -- Ron > I do > realize I could just send it in to be serviced, but 1) I am a very > DIY type of guy, 2) I'm working on a project where I'll need to > maintain a lot of decks, and I can't wait around for servicing. > cheers, > > David -------------- next part -------------- An HTML attachment was scrubbed...

When nothing changes when cleaned and the belt feels solid, belt change is not likely to improve things. It might be the left tape guide pivot is getting stuck and the tape guide is out of adjustment. This does result is incomplete erasure of previous recordings as well! Test whether both tape guide pivots are working freely and not sluggish. The only thing to feel on the pivots is the (pretty strong) spring force.

Here is what I learned and did: There are three incandescent lamps, PL601,602,603, which are on when these functions, Record, Play and Pause, are enabled using front panel pushbuttons. These lamps are transistor driven and are white, 3mm dia., 24 Vdc, 24 ma. These white (yellowish) lamps shine thru colored windows on the front panel. Red for Record, green for Play and Pause. I had trouble finding a replacement with the same specs. I found lots of lower voltage and/or higher current 3mm lamps. These would require a dropping resistor (1/2 watt and would be cumbersome to install. There was the fear that I would toast the driver transistor as well. There is not much room in there. The Play lamp turns out to be the easiest. That is not usually the case, right! Then Neil Sturtevant [esteyes at cox.net] sent this link. http://www.newark.com/cml-innovative-technologies/01145600/lamp-bi-pin-t1-24 v-0-58w/dp/93K2155 This is a nice bulb with a plastic shell and stiff radial (Bi-Pin) leads, 3mm, 24vdc, 24ma. I just cut the original lamp leads at the bulb and soldered the bulb leads onto the wire ends with some protective shrink tubing over the connections. No soldering to the PCB necessary. The bulb shell is a little harder to push into the rubber bulb lamp boot that is in the chassis panel. A diffused white LED (cathode to ground side) with a series resistor, as suggested, would also work. A little harder to install but would last forever.what ever that is? Thanks Ron. If anyone is doing this and want some more info please contact me. Thanks for the support thru naktalk.

I am the original owner of a black Nakamichi 480 deck and love it. It is the only to go! Recently the Play (PL602) indicator lamp has burned out. I have downloaded the 480 manual and found a mention of the lamp replacement in a few postings. I have looked at several parts suppliers for a replacement that meets the following: 3mm, radial leads, 24 Vdc, 20 ma, and the closest I find is a nice one in other respects except it is 14 v at 40 ma. The 3mm radial lead lamp is the only one that will slip into the rubber boot on the back of the lamp holder. I can use a dropping resistor (1/2 watt ain't pretty) and run the lamp at about 9 v to get the same brilliance as the Pause lamp. This is not original but I could live with it. I guess I could use a white LED and just get the brightness I get. Then I could just change all three. I checked with Digi-Key, Radio Shack, Parts Express, All Electronics (they had the 14v/40ma). Question: Is this lamp driven with a transistor or the Play push button? It's driven by a transistor. Electrically, the closest match to the original can be achieved by a diffused white LED (cathode to ground side) with a series resistor. Choose the series resistor for 10mA It won't be 'original', and you won't get the exact effect, but it will work. -- Ron If it is transistor driven then I would worry about the 40 ma vs, 20 ma. I cannot tell much by trying to read the fine print on the schematic in the online manual. Please advise, Richard -------------- next part -------------- An HTML attachment was scrubbed...

If your tapes were recoded on lower cost machines, a deck with adjustable PB azimuth would be beneficial., allowing you to wring every bit of treble response in the tapes. Unfortunately, such decks tend to be expensive. Investigate the CR-7. Alternately (and depending how important to you is sonic quality of the result), you could do with a BX-300 or similar deck. Align the PB head by ear for each cassette.

A subject close to my heart - This is a never ending quest I have been on for years Bob...I share the very same reasons that I came to the NakTalk list. I not only have thousands of live shows from various sources but am a taper myself and have numerous audience masters of my own recordings... With improvements in digital technology every few years I am always re-transferring my shows to the digital medium and constantly strive to get that last ounce of analog output from the source tape (its always the source that counts the most). IMHO, you definitely need a machine which has playback azimuth adjustment built in as a feature or one where you don't mind messing with the PB az. screw (which is blasphemy to many purists on this forum)... That said, your obvious choices are the CR7, Cassette Deck 1, the DR1 or the TD500 and then there is the Dragon and the TD1200 which have the NAAC feature... I personally now own CD1, DR1, TD500 and the Dragon (maybe soon I will also have the CR7)...But to my ears the Dragon produces the best playbck because it has slightly better circuitry in audio re-production...If that is not within your budget then I would go with either the DR1 or the CD1 (both are essentially the same machine)... One other thing to note is that I have other non-PB az. feature decks like the 580 and I have to say I find the older Nak's have a lot more warmth and you can easily access their PB az. screws quite easily...You may be able to save yourself some money as you can go for a good 2 head Nak and then adjust the PB az to your hearts content (I doubt you care so much about recording like me...I stopped recording analog from mid-nineties and fail to understand why anyone would use analog to record audio unless its not on reel) On Wed, Jul 22, 2009 at 6:18 PM, Bob wrote: > I have hundreds of live concert recordings on cassette that I would like to > listen to and/or transfer to digtial.

I > need help on how to handle and solve this problem. You need to trouble shoot the capstan motor. Start with lubricating the capstans bearings. You can lift capstan washers, then place a *small* drop of light machine oil on each capstan bearing. Make sure to avoid any oil on the capstan itself. For a more thorough job. the motor must be be disassembled and the bearings oiled from the rear as well. It the above does not solve the problem, you likely have an electronic problem, located on the motor PCB. The first component to suspect is the driver IC, but any component could be the culprit, including the PCB itself. . At this point, nothing can be done without the proper tools and the knowledge of using them.

My understanding was that it clicks when it cannot locate the higher freq it needs to align the NAAC and if your tape starts soemwhat quiet the NAAC is confused and if you fwd to a slightly louder part it is able to align quickly... I have similar experience where some of my live show audience recordings start somehwhat soft with audience chatter and then eventually the music picks up....and until this loud portion appears the Naac keeps trying and eventually clicks.....this is not the case when I simply fwd the tape to the loud portion and start playback....is this not a normal phenomenon - even on a fully calibrated deck??? Can the quiet passage of sound at the very start throw the Naac for a loop???

It is designed to make quick adjustments in the first 10 seconds of audio, but the audio must have 3-5kHZ AND treble above 10kHz to operate properly. This mode is the 'blinking light' mode. After the initial NAAC azimuth adjustment, the 10kHz band is monitored and any further adjustment is made very slowly. Direction light stops blinking in this mode. In the case of no audio, or of audio with no higher harmonic content, the NAAC will happily wait until suitable signal is present in the music. It may well be that percussion is a tricky signal for NAAC to lock onto. The first step is to listen in mono as you begin to play the tape. Significant phase sound will tell you that the play azimuth error is present. If the phase error reduces and the treble returns, then NAAC has found the correct azimuth. Before any NAAC adjustment or repair is contemplated, always open the cassette holder, confirm the azimuth pointer returns to center position, and disconnect plug CN-5, the azimuth motor, from the NAAC printed circuit board. Now, play your percussion tape. How does it sound? What you have done by this simple procedure is to make the Dragon a normal cassette deck with fixed play head azimuth. You will see blinking lights, but no adjustment occurs. Dirty heads, capstan bearing friction, capstan motor drive problems, sticking guide bases, excessive take up torque, and head tilt of penetration problems can all cause what you hear, while the NAAC is working perfectly! I have had one case of orange cap disease which affected the NAAC C823,C828,C859,and C860 were changed in the frequency filter circuits. C859 or 860 are the principal culprits. Note however, that changing these capacitors requires a complete NAAC realignment. For any of you stuck with a clicking NAAC, try disabling the azimuth motor as described above. Download the Dragon manual, found on our wiki, for the location of this connector. tom brucker -----Original Message----- From: naktalk-bounces at naks.com [mailto:naktalk-bounces at naks.com]On Behalf Of kannan srinivasaraghavan Sent: Friday, July 24, 2009 3:49 PM To: ural durusu; Talk about Nakamichi Cassette Decks Subject: Re: [naktalk] DRAGON NAAC Your Dargon needs complete alignment including head/ NAAC alignment.

Message-ID: <000001ca0ce7$cd766eb0$68634c10$@net> Bob, I would second Rajiv's suggestions. A little while ago I purchased a DR-1 off of ebay at a very good price considering its near new condition. This deck has the playback azimuth adjustment control built-in and it works great. I sensed that some of my old tapes made on my BX-150 were a little dull and they sound great on the DR-1 after slight adjustment. The DR-1 has a detent at the zero position so you can always return the azimuth control back to its original position.not something you could do reliably with only a crude screw adjustment. I like the control of manual adjustment myself rather than the gee-whiz-bang electronics of the higher priced machines (just my humble opinion).

A subject close to my heart - This is a never ending quest I have been on for years Bob...I share the very same reasons that I came to the NakTalk list. I not only have thousands of live shows from various sources but am a taper myself and have numerous audience masters of my own recordings... With improvements in digital technology every few years I am always re-transferring my shows to the digital medium and constantly strive to get that last ounce of analog output from the source tape (its always the source that counts the most). IMHO, you definitely need a machine which has playback azimuth adjustment built in as a feature or one where you don't mind messing with the PB az. screw (which is blasphemy to many purists on this forum)... That said, your obvious choices are the CR7, Cassette Deck 1, the DR1 or the TD500 and then there is the Dragon and the TD1200 which have the NAAC feature... I personally now own CD1, DR1, TD500 and the Dragon (maybe soon I will also have the CR7)...But to my ears the Dragon produces the best playbck because it has slightly better circuitry in audio re-production...If that is not within your budget then I would go with either the DR1 or the CD1 (both are essentially the same machine)... One other thing to note is that I have other non-PB az. feature decks like the 580 and I have to say I find the older Nak's have a lot more warmth and you can easily access their PB az. screws quite easily...You may be able to save yourself some money as you can go for a good 2 head Nak and then adjust the PB az to your hearts content (I doubt you care so much about recording like me...I stopped recording analog from mid-nineties and fail to understand why anyone would use analog to record audio unless its not on reel) On Wed, Jul 22, 2009 at 6:18 PM, Bob wrote: > I have hundreds of live concert recordings on cassette that I would like to > listen to and/or transfer to digtial.

If the issue is a tape recorded on a machine where the azimuth was slightly out, or at least different from that on the playback machine, then any one of the Naks with adjustable azimuth for playback will be ideal. Can't beat it, IMO. But if he issue is a recording that's gone dull, I don't think you'd do better than use - sorry guys - a Pioneer CTS830S or its like that uses a FLEX circuit. To quote Marc, another member: "FLEX is very clever really, by assuming a standard frequency curve/distribution for recorded music, and boosting any frequencies where these are deficient, not only due to alignment or azimuth problems but due to wear (loss of magnetic particles) or loss of magnetic retentivity. And this, azimuth control cannot do. The range of frequencies subject to boosting seems to cover the entire spectrum and is not just more straightforward HF lift effect of Play Trim. If anyone has not tried this feature with a truly nackered, old tape......it's quite an eye/ear opener!!" In other words, it's a bit like having a graphic equaliser that self-adjusts in real time. Otherwise, the Pioneer isn't as good (IMO) as a similar 3 head Nak for Dolby B recordings for the most part (altho' they lick them all with regard to w/f when they are performing to spec) but they do make v good recordings (again IMO) using Dolby S. (Mind you, that's not a fair comparison - they never did compare with the prices of Naks, and they certainly fetch a lot less than a Nak in the 2nd hand market. So, you get what you pay for ... except with regard to the Flex circuit ... oh yes, and the w/f, too.) Needless to say, the Pioneer isn't my first line for recording - that goes to the ZX9, with an Arcam Delta 100 second (or first if I w ant Dolby S) - but it is always my first line for playback if I want to re-record a dull or otherwise deteriorated tape.

Bob, I would second Rajiv's suggestions. A little while ago I purchased a DR-1 off of ebay at a very good price considering its near new condition. This deck has the playback azimuth adjustment control built-in and it works great. I sensed that some of my old tapes made on my BX-150 were a little dull and they sound great on the DR-1 after slight adjustment. The DR-1 has a detent at the zero position so you can always return the azimuth control back to its original position.not something you could do reliably with only a crude screw adjustment. I like the control of manual adjustment myself rather than the gee-whiz-bang electronics of the higher priced machines (just my humble opinion).

IF a particular tape was recorded with quite a significant Azimuth off position recording ( I have a sample originally recorded cassette for tests after NAAC alignment) it will click from the beginning till the end of such recording - but not when a HF signal is present like hand claps or crowd noise- shows that the NAAC requires recalibration- probably 15Khz NAAC adjustment. It can also be due to 5 Khz phase adjustment- I do not judge Dragon troubles without looking at the machine. Tom had described the functioning of NAAC well in the other reply- read to understand what happens. 95+ percent of the Dragons that I recd (sources- ebay buys/outside buys/servicing etc) all needed NAAC calibration - sometimes even the 5 Khz phase adjust circuit changes. Fortunately large number of Dragon owners think that their Dragon is perfect ! - sorry to say -no it is not functioning well in my experience. This adjustment is not for every one as without proper tools you end with messy NAAC functioning - requiring immediate visit to a qualified service shop. So I do not advise this to many like Belt change in a Dragon.I was accused of not encouraging DIY here in this Forum but sorry to say my experience with Dragons is that you need all the tools including expensive DMM or VTVM to trouble shoot plus invaluable Dragon experience. Good news is that once properly aligned - I have seen the NAAC works without issues for years. So It is wrong to say that the Dragon is a troublesome machine. Also note that NAAC operation depends on so many tape transport variables. Tom had described nicely in the other reply. That is why Dragon requires good continuous touch with Dragon servicing to know the cause looking at the symptoms. Also I have been seeing Orange cap issues in Dragon as well - Finally NAAC troubles can be due to even orange caps! kannan --- On Fri, 7/24/09, Rajiv wrote: > From: Rajiv > Subject: Re: [naktalk] DRAGON NAAC > To: "Talk about Nakamichi Cassette Decks" , "ural durusu" > Date: Friday, July 24, 2009, 5:44 PM > Kannan > > Are you saying that the Nak should not click if you start > playback in the somewhat quieter parts....the description > below is pretty much what I am seeing on my Dragon as > well.....now I am well aware that I should get it > recalibrated and I will but I am asking this question for my > knowledge - Is a fully calibrated Dragon never suppossed to > click? > > My understanding was that it clicks when it cannot locate > the higher freq it needs to align the NAAC and if your tape > starts soemwhat quiet the NAAC is confused and if you fwd to > a slightly louder part it is able to align quickly... > > I have similar experience where some of my live show > audience recordings start somehwhat soft with audience > chatter and then eventually the music picks up....and until > this loud portion appears the Naac keeps trying and > eventually clicks.....this is not the case when I simply fwd > the tape to the loud portion and start playback....is this > not a normal phenomenon - even on a fully calibrated deck??? > Can the quiet passage of sound at the very start throw the > Naac for a loop??? > Sent via BlackBerry by AT&T > > -----Original Message----- > From: kannan srinivasaraghavan > > Date: Fri, 24 Jul 2009 13:49:26 > To: ural durusu; > Talk about Nakamichi Cassette Decks > Subject: Re: [naktalk] DRAGON NAAC > > > > Your Dargon needs complete alignment including head/ NAAC > alignment.

What is strange for me is it is working properly for both directions with the audio test tapes like 10 Khz -15db azimuth tape, 1khz 0db head height tape and 315 hz operating level adj. tape these tapes are belongs to AKAI company. When I load a music cassette even formerly recorded by the DRAGON and played back without problem upto now, starts to click for forward play from now. When I press any of the play buttons while the cass. holder open the pointer centers the azimuth mark, After aligning the PH with the azimuth tape and check with the DC voltmeter for both directions display shows 0,03V. When I connect the CN5 and engage to playback with the azimuth tape both directions works perfect pointer hits the center within few seconds. But all these fails for the forward playback when I load a music cassette. Also it plays very good when the CN5 is disconnected. Casettes are all TDK and, new tape quality is not the reason. What I am thinking is I should find the height and tilt gauge and check the PH and RH. But it is hard to find that gauge. Regards. Ural NAAC is not a simple circuit. It is designed to make quick adjustments in the first 10 seconds of audio, but the audio must have 3-5kHZ AND treble above 10kHz to operate properly. This mode is the 'blinking light' mode. After the initial NAAC azimuth adjustment, the 10kHz band is monitored and any further adjustment is made very slowly. Direction light stops blinking in this mode. In the case of no audio, or of audio with no higher harmonic content, the NAAC will happily wait until suitable signal is present in the music. It may well be that percussion is a tricky signal for NAAC to lock onto. The first step is to listen in mono as you begin to play the tape. Significant phase sound will tell you that the play azimuth error is present. If the phase error reduces and the treble returns, then NAAC has found the correct azimuth. Before any NAAC adjustment or repair is contemplated, always open the cassette holder, confirm the azimuth pointer returns to center position, and disconnect plug CN-5, the azimuth motor, from the NAAC printed circuit board. Now, play your percussion tape. How does it sound? What you have done by this simple procedure is to make the Dragon a normal cassette deck with fixed play head azimuth. You will see blinking lights, but no adjustment occurs. Dirty heads, capstan bearing friction, capstan motor drive problems, sticking guide bases, excessive take up torque, and head tilt of penetration problems can all cause what you hear, while the NAAC is working perfectly! I have had one case of orange cap disease which affected the NAAC C823,C828,C859,and C860 were changed in the frequency filter circuits. C859 or 860 are the principal culprits. Note however, that changing these capacitors requires a complete NAAC realignment. For any of you stuck with a clicking NAAC, try disabling the azimuth motor as described above.

Do you get any action at all when you press play or Rew or FF? If you hear or see things trying to move your problem is likely due to solidifying lubricants in the transport. The deck should have complete service by someone who knows the machine and has the test and alignment equipment to do it. There are several choices among those in this group who are capable of doing such a job. Please resist the temptation to take the machine to your local electronics servicer who says he'll be able to fix it. Most of them can't and will injur the machine while trying.

To perform well, they require regular maintenance service, not unlike the regular tune-up all cars need. Owner maintenance (cleaning, demagnetizing) is also necessary, as far as it goes, but is in addition, not instead, routine service (belt replacement, touching up internal adjustments, lubrication, etc.). every couple of years or so. Many owners do know this and also know how to service their decks. Those that do not (or wish not) should seek professional help. In your case, it is quite possible nothing bad has happened to your ZX-9 (excellent machine, BTW) except neglect. Since you lack the experience, I suggest you seek a competent technician to service your deck. Do make sure the person is experienced with Nakamichi decks (your deck shouldn't be their Guinea pig). Depending on where you live, this can be very easy or impossible. If yous are forced to ship your deck to a tech, be aware that there are several excellent techs on this forum and I am sure some will speak up.

The motor tends to develop a dead spot on the armature. When the motor stops in that exact spot, it won't turn at all until it receives a slight turn. Once its back on a contact spot on the armature it works fine again. I have tried cleaning these motors to no avail. Replacement is the best way. It's not all that tough a job if you're good at mechanics and have the right tools. No need to disassemble any of the points which have to do with the alignment of the deck. Best of luck.

The steps for repairing your deck are: 1. I dentify the problem. 2. Locate the faulty component(s) 3. Repair or replace it/them. I am nor sure how *we* can advise *you* whether *you* can fix it. You are the one who should know. For starters, though, I would suspect the cam motor itself. As further suspects, the cam motor contacts or its driver circuitry. To check, remove the cover, press PLAY and ttry to help the cam motor along with a finger. If the deck springs to life, the cam motor could have developed a 'dead spot' and needs to be either rebuilt or replaced. -- Ron -------------- next part -------------- An HTML attachment was scrubbed...

I am of the same realization on these CR 7 cal boards Here is the thinking process. I am a self employed design person, wearing many hats doing prototype work.. Schematic design, board layout, programming, etc. On a 4 to 5 week cycle I run numerous boards, all merged onto a large panels spaced .01 inches apart. The shapes and sizes vary. Since I shear the individual boards out myself, there is a linear pattern I have to observe while doing this merging process to allow the boards to be sheared out in individuals with out chopping others in half. Also since the individuasizes vary, there is always a little strip some where on these panels that I am hard pressed to fill. Seeing a request form a Nak user is what lead me down this path. Usually, it's little personal design projects that end up in these small voids from my own wish list. So there is flexibility built into the way things are done. Running 30 blanks of the CR 7 cal boards is of little consequence if there is 10 pcs or so left over. They will only get sheared out and populated on an as needed basis and the remainder just filed in a board draw.for future reference. Making the Cal boards available this time circumvented a little head scratching for ideas. Normally, if there is a market I would naturally add some Upc enhancements to a product such as this, but chose to keep it as is, simple and practical. This leaves time for more important considerations as they arise. --- On Mon, 6/1/09, Tom Brucker, Nakdoc wrote: From: Tom Brucker, Nakdoc Subject: Re: [naktalk] CR 7 Calibration Boards Available To: "Talk about Nakamichi Cassette Decks" Date: Monday, June 1, 2009, 10:34 PM Ray, Don't.

Of course being here gives the project a good start, though he certainly needs support from service guys like your good self.

I am of the same realization on these CR 7 cal boards Here is the thinking process. I am a self employed design person, wearing many hats doing prototype work.. Schematic design, board layout, programming, etc. On a 4 to 5 week cycle I run numerous boards, all merged onto a large panels spaced .01 inches apart. The shapes and sizes vary. Since I shear the individual boards out myself, there is a linear pattern I have to observe while doing this merging process to allow the boards to be sheared out in individuals with out chopping others in half. Also since the individuasizes vary, there is always a little strip some where on these panels that I am hard pressed to fill. Seeing a request form a Nak user is what lead me down this path. Usually, it's little personal design projects that end up in these small  voids from my own wish list. So there is flexibility built into the way things are done. Running 30 blanks of the CR 7 cal boards is of little consequence if there is 10 pcs or so left over. They will only get sheared out and populated on an as needed basis and the remainder just filed in a board draw.for future reference. Making the Cal boards available this time circumvented a little head scratching for ideas. Normally, if there is a market I would naturally add some Upc enhancements to a product such as this, but chose to keep it as is, simple and practical. This leaves time for more important considerations as they arise. --- On Mon, 6/1/09, Tom Brucker, Nakdoc wrote: From: Tom Brucker, Nakdoc Subject: Re: [naktalk] CR 7 Calibration Boards Available To: "Talk about Nakamichi Cassette Decks" Date: Monday, June 1, 2009, 10:34 PM #yiv188717080 #yiv1224425587 {font-family:Geneva, Arial, Helvetica, sans-serif;font-size:9pt;background-color:#ffffff;color:black;} Ray,  Don't.

Message-ID: <86300.33760.qm@web33302.mail.mud.yahoo.com> HI kermit I am very close to recording now just that i bought an EV RE20 ofcourse. I missed a Shure 300 Ribbon. Senheiser MD441U used did not come closer to a brand new RE20 on ebay ( much lower than its regular store price. Used RE20s are getting sold at this price and so I bought it knowing its value). I did not try too hard to obtain other alternatives mics. Tested the mic with Audio Technica Mic impedance transformer as MX100 doe snot have balanced input and commercial adapters were not very helpful to connect it either. This Transformer helped connecting the mic without any problems and solved gain issues a bit. Still MX 100 gain is tricky as it is part of the input impedance network . Too high a Gain is needed if the singer is about 6 inches or more from the mic and such gain settings picks up little noise. Lower setting with Dolby C setting makes the recording excellent but peak signal level reaches just 0Db. I would like to record around +3-5 db on Naks to get maximum dynamics.  The recording is fantastic for a home setting which is not exactly quite lilke a studio and sound is natural and absolutely no coloration/sibilance or distortion as specified. This mic is an excellent choice as you described   Now my wife is not ready this week due to her throat conditions to actrually record. We did few trials to check the quality.    Now I would like to try out your pre for MX 100 to check whether I can obtain higher gain without noise so that the singer need not sit very close to the Mic. I am happy to learn this first step to recording ( home).   My another question is about placing this mic - Do i have to make its top face the Vocalist horizontally parellel to the ground plane or tillt up from lower level like PA mics.  Or do I tilt this mic down from a higher level ( using a boom) keeping the Mic hanging on shock mount? There is no specific application help from the mic manual and I thought this would be interesting to know   So let me get some more ideas  kannan     --- On Tue, 5/26/09, Kermit Gray wrote: From: Kermit Gray Subject: Re: [naktalk] What is the suitable Mic for vocals - using MX 100 ? To: kannan_srinivasa at yahoo.com, "Talk about Nakamichi Cassette Decks" Date: Tuesday, May 26, 2009, 6:22 PM Hi Kannan, Always glad to help! Of the choices you've narrowed it down to, I'd suggest the EFV RE20 because it will do better placed back from the singer, and its tone will remain the same with changes in distance because of the Variable-D design. Another reason I like the RE20 is you can record quite close up yet give an excellent recording that doesn't have that "too close" mike sound, although the recording will be rather dry, because it effectively rejects room noise. If you don't have a good sounding room, this is good news. The EV 635A is an overlooked bargain because it's one of the few mikes that can be used close-up and also not have that "too close" mike sound, yet it is an omni and therefore will capture some room sound sound. These two mikes are as close to foolproof as you can find, in my opinion. The last time I recorded female Indian vocals the recording was on location, so I used my EV RE20 (which was stolen a few weeks later), placed two feet back for one of the singers, who had a strong voice; and 1 foot back for the second singer, who had a quieter voice. I plugged the mike into my Nak 550's BLEND mike input, and had excellent results. The Sennheiser MD421U tends to lose low-level detail more than two feet back, whereas the MD441 is fine as far away as 6 feet. The Beyerdynamic M260 has been made since the 1960s. The comments the seller made about the M260 are spot-on for the older (pre-1990) models, but in recent years Beyerdynamic has retuned the M260 slightly. New production models of the M260 have a built-in bass cut, and aren't as bright as the pre-1990 models. I'd forgotten about the MXL R-44 that Marc mentioned, it is surprisingly good. That said, the sound of ribbon mikes is dramatically affected with changes in preamplifier loading. This is good news/bad news -- it lets you shape the tone by changing loading, but learning to do this can be problematic, time consuming and frustrating for a beginner. That's why the growing trend is to build a preamp into a ribbon mike to ensure the mike has the ideal loading. I expect the MX-100 to have no problem with any of the mikes I recommended to you, with the caveat that if you take the traditional approach to recording Indian vocal music (mike 4 to 6 feet back, mounted overhead, aimed down at the singer), then you'll have too much noise with ANY mike you pick. But closer in, you're okay. Like many have said, tinker with placement to find the best balance. Whichever mike you pick, connect it to the BLEND input of the MX-100, and turn the LEFT and RIGHT inputs fully down. This gives you a mono-to-stereo output with no hassle. If for some reason the mike you choose doesn't have enough output for the MX-100 let me know and I'll make you a dead-quiet booster preamp to match the MX-100 for free. (But I don't expect any problems, of course.)

I am of the same realization on these CR 7 cal boards Here is the thinking process. I am a self employed design person, wearing many hats doing prototype work.. Schematic design, board layout, programming, etc. On a 4 to 5 week cycle I run numerous boards, all merged onto a large panels spaced .01 inches apart. The shapes and sizes vary. Since I shear the individual boards out myself, there is a linear pattern I have to observe while doing this merging process to allow the boards to be sheared out in individuals with out chopping others in half. Also since the individuasizes vary, there is always a little strip some where on these panels that I am hard pressed to fill. Seeing a request form a Nak user is what lead me down this path. Usually, it's little personal design projects that end up in these small  voids from my own wish list. So there is flexibility built into the way things are done. Running 30 blanks of the CR 7 cal boards is of little consequence if there is 10 pcs or so left over. They will only get sheared out and populated on an as needed basis and the remainder just filed in a board draw.for future reference. Making the Cal boards available this time circumvented a little head scratching for ideas. Normally, if there is a market I would naturally add some Upc enhancements to a product such as this, but chose to keep it as is, simple and practical. This leaves time for more important considerations as they arise. --- On Mon, 6/1/09, Tom Brucker, Nakdoc wrote: From: Tom Brucker, Nakdoc Subject: Re: [naktalk] CR 7 Calibration Boards Available To: "Talk about Nakamichi Cassette Decks" Date: Monday, June 1, 2009, 10:34 PM #yiv388961159 #yiv188717080 #yiv1224425587 {font-family:Geneva, Arial, Helvetica, sans-serif;font-size:9pt;background-color:#ffffff;color:black;} Ray,  Don't.

As noted by jaetee at tampabay.rr.com, there are two 0dB points in the bias adjustment and it's very important to get the correct one. Just follow the manual instructions. I doubt the oscillator is bad, as is works fine for two of the three tape formulations. However, adjustment could be out of range.due to quite a few other circuit failures (any of many resistors plus a few caps are the main suspects). For this reason, I doubt troubleshooting by remote control will work well in this case. My advice is to have a professional look at the deck. Good luck, -- Ron Peter Tanner wrote: > Thanks.

This information is fed to a processor that, based on tape thickness, calculates time. It turns out that how tightly the tape is packed has little bearing on time display accuracy. However, Nak allowed only three tape lengths (C-46, C-60 and C-90), while many people use C-100, C-110 and C-120 cassettes. -- Ron Antoine Deschênes wrote: > On many decks, the counter just counts the number of revolutions of > the hub.

Whatever you do - you have to do it gently. Genrally you do not remove the pad lifter to clean the main head gap which is anyway accessible. Use Chemoise leather sticks available at MCM to clean it. I think Rajive' three head needs track alignment / probably azimuth as well - needs Nakamichi tapes / gauges without which the head alignment is pretty difficult ( almost impossible to be as precise as it should be). He is facing the playback issues due entirely to Head alignment problem Read 582 service manual for explanation on head height/azimuth adjustments on nak three heads kannan --- On Fri, 6/12/09, Bob Naylor wrote: > From: Bob Naylor > Subject: Re: [naktalk] Best way to clean under the pressure pad lifter... > To: "Talk about Nakamichi Cassette Decks" > Date: Friday, June 12, 2009, 3:39 PM > On my > ZX7 I pulled the lifter off.  It was just a press > fit.  Don't know if they're all like that or > not???  Bob N > > --- On Fri, 6/12/09, Rajiv Pandey > wrote: > > > From: Rajiv Pandey > Subject: [naktalk] Best way to clean under the pressure pad > lifter... > To: naktalk at naks.com > Date: Friday, June 12, 2009, 9:03 AM > > > All, > > What is the best way to clean the heads under the pressure > pad lifters on the 3 head Nak decks?

Message-ID: <315048.83220.qm@web36805.mail.mud.yahoo.com> Hi friends, I was told to use a tooth pick to lift the pressure pad lifter and then clean and put it back with firm pressure till it fits onto the head by some individual/s. I did that and saw no difference in the sound or dirt coming off the pb head. However, Jeff Galin of ESL told me NEVER to do that because the head alignment could be affected and might need realignment. He also mentioned it was never necessary to clean under the lifter as the tape never contacts the head in that territory ever. After cleaning the pb head with the lifter on, I use compressed air to blow dry the head without freezing it,and that I presume will blow off any particles under the lifter if at all.

Nakamichi ever made a sharp tipped cleaning pen to facilitate cleaning into the sharp corners of the playback head fitted with a pressure pad remover. One old timer used a long toothpick to gently coax dirt out of the corners, although I have never done that myself and treat all tape head surfaces as carefully as camera lenses.

Message-ID: <719661.14846.qm@web30204.mail.mud.yahoo.com> Hi Rajiv, The pressure pad lifter is pressed fit on all decks. While the tolerances on the pressure pad lifters are not known, removing them and fitting them back MAY cause minor changes in head alignment. The best way of cleaning I have found, is to remove the lifter and give the heads a good cleaning with a broad cotton swap and IPA. On the many times I have done this and fitted the pressure pad lifter back, I have checked and observed no changes in head alignment. However, removing the pressure pad lifter is an exercise in caution and must be done very carefully. The next step to cleaning the heads is to  get the rest of the tape path cleaned as well. Check the condition of the pinch rollers - most times they can be cleaned. Nest, demagnetize the heads well. There a a few good how-to on demag procedures on the net. Then you can evaluate if your deck needs a re-alignment. And if it does, I recommend sending to one of the many good service people who are here on Naktalk. A good once over will give you many years of faultless, musical enjoyment.

The perfect way to nail it is to use a deck like the CR series and the Aiwa F series decks which have a built in computer that compares spool speeds to give you a pretty accurate reading of elapsed and remaining times. The important thing is to set the tape time correctly. The CR7 though, doesn't have a setting for C46s with a large hub and that does make a difference. Another cool machine that does this in retro style is the Technics 9900US that has an analogue style needle indicator for tape time! Never tried it out yet, so can't comment on it's accuracy. Cheers!

While soldering back the correct 2SD1286, I did not see it! After having wired these 2 points, everything works, and VR601 is again active. I have 2 questions about this "regulation": 1. I have noticed that if I tuned too much torque with VR601, again the memory stop function "hesitates" to stop at "0000". If I "turn down" VR601 (I would say 20° from the middle point), it works perfectly. Could it be considered as another way to detect too much torque? 2. on BX150 SM, no voltage values are indicated about the reel motor circuity. On the other hand, on CR7 SM, a voltage value is indicated at the cross point between VR601 and the SD1286 transistor (Q607 for BX150, Q648 for cr7)for each function (6.7 V for STOP, 6.5 V for FF/Rew and 4.4 V for PLAY): Should these values be chiefly the same for all Sankyo transports ? bernard Ron a écrit : > Boitrel Bernard wrote: >> I just got a BX15OE which works quite well, it needs a good cleaning >> and that's it. >> The transport is ok , all the function work however I noticed that >> without a cassette, the play function is very fast: >> >> For instance, during 15 secondes, the counter goes from 0 up to 300 on >> this BX150 and only up to 83 on my BX300E. >> >> I have mesured the voltage on th reel motor during play and FF: in >> both cases, it was 4.74V >> >> I have also noticed that VR601 has no influence on the speed of the >> reel motor!!! > > Nothing to worry about, all this is normal. > > -- Ron > > >> I have also noticed that Q608 has been changed by another type of >> transistor (the same type that that of the power supply) labelled TIP122 >> where it should be a TR 2SA953 >> >> What does that mean? >> >> thank's >> Bernard > > ========---------------------------------------------------------========= > Also check out the wiki! http://www.naks.com/wiki > ========---------------------------------------------------------========= > Naktalk at naks.com mailinglist > Maintain your account here: http://www.naks.com/mailman/listinfo/naktalk > ========---------------------------------------------------------========= > > -- Dr Bernard BOITREL Sciences Chimiques de Rennes, UMR CNRS 6226 Bat 10C, porte 127 Université de Rennes 1, Campus de Beaulieu 263, Av.

Azimuth is often off on commercial tapes, and between decks. A slight azimuth misalignment will cause Dolby to completely screw up. I think that worn tapes also don't work too well with Dolby. Oh, and you'll always hear more HF with Dolby NR turned off in softer passages, Dolby encoding boosts the treble to lower the hiss in these cases. Le 2009-06-16 10:44, Rajiv a écrit : > Really?!!!

Message-ID: <503751.35991.qm@web36803.mail.mud.yahoo.com> Rajiv, I agree with Kannan here because what he says are pure true facts. I have never bought a brand new Nak but have over 15 Naks.... and some more on the way. What Kannan tried to imply here is that when you have a Dolby recorded tape,( correctly recorded, I might add) and have the switch off, you hear the added hiss and high fidelity. When you hit the dolby button, the high fidelity stays (does not dull out) while the hiss is eliminated. This is a dolby recording to begin with. I have observed this in all Naks of mine,,, some professionally aligned and calibrated and some off ebay sounding phenomenal that behave in this fashion. Its only when you press a dolby on button to a non dolby recorded( encoded) tape that you tend to flatten the sound. But then dolby was never intended to be used without first encoding it duringrecording!

If you play back the Dolby encoded tape without Dolby it will sound too bright.   If you playback a non-Dollby recorded tape with Dolby, it will sound dull. Bottom line- Dolby decoding will cut the highs-very audibly. It's with Dolby encoded tapes that the high frequencies will be cut down to the correct level.   All the best,      Leon(The Audiomayvin, Montreal(514)739-5403) __________________________________________________________________ Yahoo!

In many (most?) cases, though, the deck will be fine. To be on the safe side: if you have a variac, try bringing the deck up on very low line voltage (say, 30VAC), then slowly increasing it in about 30V steps, all the time monitoring line current. Go to the next voltage step after a while (say, a couple of hours or so), and only if line current is normal (or has decreased to normal). The above allows leaky supply filter caps to reform. If it reveals high line current that does not diminish with time, you'll need to trace the cause and repair before proceeding. Once you reach proper operating line voltage, test all functions of the deck. In most cases, that's it. If you do not have a variac, a reasonable substitute is powering the deck up in series with a lamp socket. Start with a 25W lamp in the socket, then change to 40W lamp, then to 60W and 100W, then directly plug it in. Voltage steps will not be ideal at all, but electrolytic caps will still reform -- hopefully, with no mishap. Or, to save all this trouble, just plug it in, take a deep breath and turn it on. Let it sit for a while without pressing any button. just smelling the air :-).. Then, test operation. You may wish to remove the cover first, to better discern undue smoke.

It is the metal bias that is not made by any one anymore. TDK's can be purchased on ebay and other web retailers for a very good price. Of course the quality of newer tapes is not as it was in early 80s' or late 70s'. For vintage cassettes,( all types and years) ebay is the Mecca, albeit pricey.

I switched back to the original tape on the <> and it had the same problem again. I tried recording a tape with it, and it did record, and played back nicely on the 482z, but sounded muffled/quiet on other decks of mine, so I assume it needs a tune up calibration etc. However, while at first it played back it's own tape fine, after a few minutes, it went muffled on both channels, seemingly similar to the problem I noticed with the first tape I tried, but then again not exactly the same.

There's nothing obvious with the remote which would indicate that the buttons are out of alignment, dirty, or anything like that, and I took the remote apart, cleaned it, and put a little Deoxit on the remote pads without changing anything. This system works by having the preamp accept all the remote signals, and passing them to the tuner, CD and cassette by means of DIN cables. I have a normal 7 pin DIN cable between the CD and tuner.

The first thing I did when I got the deck was clean the tape path with hexanes and demag. What is really curious is that for this one tape on one side, it plays fine for a fraction of a second and the drops out the be muffled on one channel. It doesn't matter where on the tape it is so long as it's on the bad side. In the middle of the tape, it might last a little bit longer before dropping out than at the beginning of the sise.

This deck needs his D2 belt. This belt dimension is very critical for Wow and flutter spec and be specific in buying the correct belt. This will make the tape tension correct for all tapes to be moving over the heads. The muffling sound is due to insufficient tape to head contact- this can happen on one side compared to the other due to tape friction inside the shell being bit different. Correct belt should overcome this problem and play on both sides equally well. YOu can also use clear shelled tape to observe the tape movement across the head. I even broke one old tape edges to see how the tape moves across as Mirror tape is not available easily Also it is a good practice to replace the cam mode motor belt also Look at Scott Johnson web page - www.naks.com lists all links or Google for belt information along woth large number of Nakamichi related service issues in brief for your reference. also look at naks com wiki page and download appropriate service manual to understand how the transport works kannan --- On Thu, 6/25/09, bgg at nym.hush.com wrote: > From: bgg at nym.hush.com > Subject: [naktalk] RE: ailing 482z > To: naktalk at naks.com > Date: Thursday, June 25, 2009, 9:17 PM > thanks for the replies.  The > first thing I did when I got the deck > was clean the tape path with hexanes and demag.  What > is really > curious is that for this one tape on one side, it plays > fine for a > fraction of a second and the drops out the be muffled on > one > channel.  It doesn't matter where on the tape it is so > long as it's > on the bad side.  In the middle of the tape, it might > last a little > bit longer before dropping out than at the beginning of the > sise. > The other side plays ok.  The tape plays without any > problems on my > other decks. > Could this be a head alignment issue perhaps?

I had just complted setting bias & rec levels for a tape, rewound and was going to start the recording when the deck would not engage into record mode. Literally from one moment to the next. It worked fine when I was setting the levels??? Now, when I hit the record button, the red light flashes briefly and then goes out. It won't stay on.... and it won't record. Luckily, I also have an RX-505 wired to the same system, so I was able to use that deck instead. But now I've got an obvious issue with the 582. Power off and power back on did not fix it.

I suspect I might be able to fix that by adding another wire to connect the DIN connector shields, but that's not a big deal to me, since there are barely 8 radio stations around here that are worth a preset. But if anyone knows where I could get an original Nak remote tuner or CD remote cable, let me know. I found an original Nak tape deck remote cable on the auction site, but for the others I'm having to use standard DIN cables. I had to bend a couple of the pins on an 8 pin DIN to get the CD cable to fit, but once I did it works fine. Thanks!

Obviously, you need to do some testing (a.k.a. troubleshooting). Assuming you have (at least) the service manual (you can download it from the Naks.com wiki page) and a multimeter, proceed as follows: Open up the deck. Locate the logic board and find diode D439. Measure anode voltage (w.r.t.ground) as you toggle the record prevention tab. Should be logic HIGH (close to +5V) with tab actuated and LOW (about 0V) without. If not, the problem is with record prevention. If OK so far, locate IC403 on the same board. Measure pin 9. should be HIGH in STOP mode. Pressing the REC key should make it LOW while key is depressed. Measure pin 11. Should be LOW after pressing STOP, HIGH after pressing REC (with cassette in). If not, the problem is in this control logic area. Do let us know how you're doing,. -- Ron -------------- next part -------------- An HTML attachment was scrubbed...

It is usually a steel wire or cable that moves within a plastic or rubber shield. When rubber is used, a steel sheath is used to protect the rubber from being chafed by the moving steel cable. It can take many forms and in this case, it is a flat steel ribbon in a plastic casing. The beauty of this mechanism is that it needs no lubration and no maintenance. As long as it isn't kinked or bent, which can happen when removing or fixing back the transport, the Bowden is as reliable as ever.

Have your tech clean and lube the azimuth alignment unit. Make sure that the dried up lube at the end of the screw drive (where it rests at the plastic catches) is replaced. No other lube is necessary. Do not lube the threads on the screw drive because it's only going to accumulate dirt and cause problems. It has to be cleaned and that's it. Install a fresh belt and it is ready to go. Also have your tech check the Bowden cable (the blue coloured cable that causes the azimuth to changed). Make sure that it isn't bent or does not impede motion. This is another part where no lube should be applied. It is also better that your tech does a complete tape path alignment (including the azimuth alignment unit check) before declaring sucess.

This is located behind the transport in the form of two back to back boards. Most probably the fault is with some of the logic gates - this usually is a problem with the 700ZXL. The ICs are all fully obtainable with exception of the memory ICs which are harder. Does the auto-azimuth work? Check epay because there you can find ESL's idlers and some good belts.

I have replaced all the orange pp caps in all the boards except the two on the mother board which I dont have the correct value at present but I dont think replacing these will make any difference. Also have replaced the RC 4559 and RC 4558 op amps in the bias osc, rec and playback amp boards but still the problem is there. Also tested and cleaned the relay in one of these plug in boards still no luck! The 400hz test tone is working great! as are the major functions like fast forward, rewind, pause, play a. Also which will be the best source to get replacement belts and the rubber idler, looking for a supplier that can ship fast and the belts are of good quality matching the original belts and the rubber idleer.

Will it fix the problem by trying to manually straighten up the cable? Since it is directly linked to the head mechanism it can definitely misalign the heads of the deck and produce more problems...is this problem reversible or not? I ask because this is how my Dragon ended up after my last attempt to change the belts.....The calibration does not function any more (test tones are there but no calibration takes place from the L/R sensitivity controls (for both level and bias) and the reset button will not rewind the tape back to record stop mode.....Both bias and level show Odb (L/R) but as described above no calibration can be performed manually......I just hope that the deck has not ended up BLR........Any information on how to proceed with this problem would be very much appreciated...Manos Bala Ganesh Chandra wrote: > Hi Tom, > > The Bowden cable is commonly found in bicycle brake and gear shift > mechanisms.

An issue that is currently discussed here. 2. you can replace the 3 original philipps screws that holds the reel motor by the equivalement hexagonal screws for next replacement (in about 25 years) hopefully... I have one question: once the pulley of the reel motor out of the machanism, is it easy to remove the old idler tire or do you need to cut it or somethhng like that? same to put the one?

If it is a slight kink, a careful bending with your fingers could help restore the functionality. If you try to take apart and straighten the cable, you could end up having the cable curl slightly due to memory effect of a material. If the problem is substantial or the kink is sharp, my advice is to get a replacement cable from any deck that uses the older transport. Rgds BG Emmanuel Komninos wrote: Bala, Tom i do have a few questions on this issue, what happens if the "bowden cable" was accidentally bended during fixing back the transport (on a Dragon this time) resulting in same problem as Kevin describes on his 682? Will it fix the problem by trying to manually straighten up the cable? Since it is directly linked to the head mechanism it can definitely misalign the heads of the deck and produce more problems...is this problem reversible or not? I ask because this is how my Dragon ended up after my last attempt to change the belts.....The calibration does not function any more (test tones are there but no calibration takes place from the L/R sensitivity controls (for both level and bias) and the reset button will not rewind the tape back to record stop mode.....Both bias and level show Odb (L/R) but as described above no calibration can be performed manually......I just hope that the deck has not ended up BLR........Any information on how to proceed with this problem would be very much appreciated...Manos Bala Ganesh Chandra wrote: > Hi Tom, > > The Bowden cable is commonly found in bicycle brake and gear shift > mechanisms.

As the oscillator is tied to the auto-cal board, my suspicion is that a fault on the auto-computing board could cause such a problem when a deck is powered up after especially a long time. A circuit mod on the erase oscillator would definitely help prevent such problems. Regards, Bala Tom Brucker wrote: For some unknown reason the 700ZXL record heads open on one channel.

It is one of things that usually never gets faulty. One thing that could avoid the problem of getting it kinked is to remove the end that goes into the back of the alignment unit and let it dangle out. Once the transport is installed and secured, then thread the cable through the cut-out and install it.

Message-ID: I had the same problem with a RX505, it is technically almost the same as the LX5. I asked the question on naktalk in december, nobody replied, maybe because I suggested an orange cap problem... So, what happened: After disassembling, spraying some contact cleaner to the small swiches, let it sit for some time, an then: everything went fine. I even shot a spare part RX505 in a desperate condition at an auction, but finally did not need the control PCB, cleaned it up, did a whole callibration: now I have two RX working like a charm. By the way: the four knobs (2 Rec volume, bias and output) are missing, if someone could help me out, I would be grateful.

Yesterady, I removed the azimuth wire from the alignment knob, extracted the mecanism, and removed the cable totally after extraction (because its seemed to me a little bit tricky removing it from the head assembly before) Now, for reassembling, I intend to do the following: 1.re-insert the mechanism and secure it with the four screws in the front, plug the Azimuth wire back to the head Is it the correct way? I then took off the two flywheels which have some hard and darken grease at the bottom. This evening, will change the tire: it is really just like caked! I mean it is more like hard plastic that like rubber after 25 years! Now some questions: 1. any advice about the way to remove it from its grove? 2. do the shafts of the idler pulley and of the reel hub need a drop of ligth oil before reassembling? 3. Do I need to deassemble the two reel hubs in order to check any particular point? 4. Do I need to add some grease (like lithium grease) on the cam? Many thank's again bernard From bernard.boitrel at univ-rennes1.fr Wed Mar 4 12:02:23 2009 From: bernard.boitrel at univ-rennes1.fr (boitrel) Date: Wed, 04 Mar 2009 12:02:23 +0100 Subject: [naktalk] Advice for Big tire replecement Message-ID: <49AE5FBF.9060705@univ-rennes1.fr> I have red the following post which includes a special procedure for tire replacement on the classic, on the auction site of Dean Sanborn If possible on a Dragon, should be also on a zx7? thank's in advance for your thinkings about that... bernard from Dean auction sit: Got and replaced the tire. The Dragon’s transport is now rock steady during rev/ff. The mechanism seems “turbo charged” now (obviously due to no slipping). BTW, contrary to popular belief (and after I disassembled it) I concluded it IS possible to swap the tire without removing the front panel nor the mechanism. After removal of the cover, you can see the Cam Shaft and the idler, vertically mounted beneath you. You then have to remove the stoppage led assembly that’s on top left (facing the front of the Dragon) giving you better access to the Cam Shaft. You’ll have less than an inch clearance to do the swap, but you can do it: Lock/secure the camshaft using some kind of tool. Cut the old idler with anything (easier than removing it “properly”), roll the shaft and remove it. Lower the new idler, parallel to the shaft’s wheel. Place a part of the tire in place, SLOWLY (you do not want to force and bend the shaft, that’s why it’s important to somehow try to fasten the shaft, I used a metal piece that sort of “clamped” it… 4 hands would be helpful here) rotate the shaft while working the tire into the wheel with a small screwdriver. Less than 1 hour to do it even if you move gently around the shaft. I’m posting your feedback now. I’m happy Thanks, RC From BOEING747600 at aol.com Wed Mar 4 12:52:54 2009 From: BOEING747600 at aol.com (BOEING747600 at aol.com) Date: Wed, 4 Mar 2009 06:52:54 EST Subject: [naktalk] Still looking for a recording head for Nakamichi 700ZXL, please help! thanks Message-ID: Hi Everyone, I am still looking for a recording head for my 700ZXL I think I had deal with Ram for purchasing one he very kindly offered to sell me the problem being he was not able to test for continuity of both coils for resistence reading at ohms setting on a multimeter as he does not have a multimeter so I am back! to were I was!

Message-ID: Hi! My LX-3, BX-100E (idler tire replaced) and CR-1E (bad solder joints fixed) are still running just fine. Unfortunately, however, my Nakamichi 480Z is experiencing some serious problems. The most apparent symptoms are: - 'FF' and 'Rew' work, but are rather weak and a bit "choppy". - 'Play' only makes the capstans spin. The takeup spindle does not spin. The heads are not lifted up to the tape (i.e., they are lifted only about half a millimetre or so... which happens also in the FF and Rew modes). Any suggestions concerning further investigation and/or repair? Thanks!

I have a CR-1A with an odd issue - when you turn it on the transport control LED's randomly blink...sometimes individually and sometimes in groups. The deck also refuses to perform any transport control commands - won't play, FF, REW etc. Pulled it apart and cleaned all the PCB interconnects - no change but did notice the capstan motor was not turning. Oddly connecting the capstan motor pulley to the metal chassis of deck causes it to start rotating although it does not fix the blinking transport status LED's. I'm thinking perhaps a bad ground connection somewhere - has anybody seen this before and perhaps have a clue where I might start the search? As always - any and all help greatly appreciated..

They now manufacture using the TDK brand, at a number of different locations around the world. It is unlikely they still use Japan as a source due to costs. Like you, I've purchased MA & SA tapes with varying colour new wrappers, but so far they seem to record well. Hence the TDK tapes made in Japan in the past are bringing increasing prices as stocks are exhausted. IEC IV is the universal standard designation for metal particle tape formulation minimum requirement agreed to by the International Electrotechnical Commission.

It has developed some issues due to sitting unused in storage for quite a few years. The Cassette Deck is in good cosmetic condition and the playback/record/erase heads are in very good condition. It can be turned on, but is unable to do anything other than fast forward or rewind tape. When trying to play a tape the transport quickly stops in both directions. I do not know exactly what is wrong, but I have been told that counter/reel light bulbs are likely to be the cause of the malfunction. If you're able to restore this legend to its former glory or just need some parts for your own Dragon, feel free to email. I'm looking for €100 euros + shipping (the deck is located in Denmark) Sincerely, Michael B. -- Be Yourself @ mail.com!

It wouldn't surprise me if so called 'jam' actually turned out to be the main problem here, even though a fresh idler tire and belts surely wouldn't hurt, either. By manually turning what I suppose is the largest plastic gear in the whole mechanism, I am able to force the deck into play mode. After a few such attempts, the pinch rollers even started (weakly) making contact with the capstans.

In-Reply-To: Message-ID: <843775.91158.qm@web23005.mail.ird.yahoo.com> Kim, there lies your problem. Plenty has been written about how to go about fixing this: in these pages before, even a purpose made gauge to make sure the height of the rollers is the same on re-assembly as before dismantling. I do not know if it is possible to fix without dismantling, I should think not though. This is what I do, first of all I use a nut and bolt(counter sunk head, nice flat top) 4mm by 15mm, as a gauge. With the head end of the bolt resting on the cassette deck main plate, I adjust the nut to the height of the roller, (check both rollers, they should be the same). I then re-do this, but with a drop of super glue on the thread. Once sure that your gauge is accurate, put it aside for re-assembly. Undo the two nyloc nuts, one per roller and lift the rollers out. They will be tight, you may need to apply some alchohol, or penetrating oil (sparingly, keep away from rubber) to help disolve the jam. Once you have dismantled, clean away all the old grease/jam, alchohol good is for this. Assembly is a reversal , but apply one or two drops of oil to the shaft. use your gauge (nut and bolt) to get your roller assemblies at the correct height. Test and hopefully you have a fully functional deck again.

Message-ID: <16555542.1236265242859.JavaMail.root@mswamui-backed.atl.sa.earthlink.net> Paul has an interesting idea for a homemade guide height gauge. May I add a few enhancements? If you find a nut exactly 1/4" that would be a good beginning. Find a bolt with the finest pitch thread. File the end smooth and flat, and make it able to stand vertically by itself without leaning to the side. Rest the flat surface on the lower fixed mechanism plate (the one with the pinch roller bearings) and find a position where the nut can be threaded so that it fits inside the Take UP guide (NOT matching the pinch roller height as Paul instructs). Mark the face of the nut and the spot on the base plate with a marker. Now move the jig to the Supply guide (you will have to press it into the guide with your finger) , and without adjusting, confirm that the marked face fits within that guide. If the nut does not fit, stop, because your deck needs alignment by a technician with gauges. If it does fit, apply a drop of instant glue to keep the nut locked in place. You may then service and disassemble the guides, but I would recommend cleaning and installing TU before SU so you can keep the SU side intact to double check the gauge. The brass split boss which holds the guides at the proper height are friction clamps. A small screwdriver can apply a SMALL amount of leverage to release the friction and remove the brass boss. NOTE, however, that prying and twisting are not to be done! The steel shaft is press fit into soft nylon, and extreme pressure will distort the nylon and ruin the deck. I want to caution that entering this level of service for the average DIY NakTalker is risky, so do nothing that might permanently damage the deck. There are servicers who can get even a disassembled deck back into proper alignment, so STOP if you find yourself over your head and seek help! tom brucker -----Original Message----- >From: paul williams >Sent: Mar 5, 2009 7:50 AM >To: Talk about Nakamichi Cassette Decks >Subject: RE: [naktalk] Nakamichi 480Z in bad shape - What can be done? > > >Kim, there lies your problem. Plenty has been written about how to go about fixing this: in these pages before, even a purpose made gauge to make sure the height of the rollers is the same on re-assembly as before dismantling. >I do not know if it is possible to fix without dismantling, I should think not though. >This is what I do, first of all I use a nut and bolt(counter sunk head, nice flat top) 4mm by 15mm, as a gauge. With the head end of the bolt resting on the cassette deck main plate, I adjust the nut to the height of the roller, (check both rollers, they should be the same). I then re-do this, but with a drop of super glue on the thread. Once sure that your gauge is accurate, put it aside for re-assembly. >Undo the two nyloc nuts, one per roller and lift the rollers out. They will be tight, you may need to apply some alchohol, or penetrating oil (sparingly, keep away from rubber) to help disolve the jam. Once you have dismantled, clean away all the old grease/jam, alchohol good is for this. >Assembly is a reversal , but apply one or two drops of oil to the shaft. use your gauge (nut and bolt) to get your roller assemblies at the correct height.

The head block should not engage in FF and REW, only in PLAY and REC modes. If it doesn't, I doubt the reason is a worn idler. Could be the control motor belt, though. The problem could be mechanical (something around the control motor and/or the head block) or electrical.

I have a CR-1A with an odd issue - when you turn it on the transport control LED's randomly blink...sometimes individually and sometimes in groups. The deck also refuses to perform any transport control commands - won't play, FF, REW etc. Pulled it apart and cleaned all the PCB interconnects - no change but did notice the capstan motor was not turning. Oddly connecting the capstan motor pulley to the metal chassis of deck causes it to start rotating although it does not fix the blinking transport status LED's. I'm thinking perhaps a bad ground connection somewhere - has anybody seen this before and perhaps have a clue where I might start the search? As always - any and all help greatly appreciated..

On the other hand, up to now, the play, FF and REWIND functions are really strong and very fast! So I probably need to clean the tire with xylenes but my question is the following: On ZX7, such a cleaning is quite easy from above, after top removing. ON RS 303, as the transport is installed upside-down, and because of the UDAR mechanism, I think I have to release the transport from the deck. Could someone give some guidance about how to proceed? is there a trick? The second possibility is to shorten the idler spring, which is much easier to reach. What is the best to do?

To: naktalk at naks.com Subject: [naktalk] FS: Non-functioning Nakamichi Dragon Date: Wed, 4 Mar 2009 21:42:48 -0500 I'm setting my Non-functioning Nakamichi Dragon for sale. It has developed some issues due to sitting unused in storage for quite a few years. The Cassette Deck is in good cosmetic condition and the playback/record/erase heads are in very good condition. It can be turned on, but is unable to do anything other than fast forward or rewind tape. When trying to play a tape the transport quickly stops in both directions. I do not know exactly what is wrong, but I have been told that counter/reel light bulbs are likely to be the cause of the malfunction. If you're able to restore this legend to its former glory or just need some parts for your own Dragon, feel free to email. I'm looking for €100 euros + shipping (the deck is located in Denmark) Sincerely, Michael B. -- Be Yourself @ mail.com!

Then, they recommend 'FLOIL TS-1', made by Kanto Chemicals Co. Ltd. in Japan (where else). Once you get it, apply to the reel hub shaft (after disassembly, of course). I wouldn't get any lubricant on the back tension parts. See the service manual for the exploded view. Seems like a lot of trouble.

I just assumed that if coming from the idler reel, would do it in both directions? But in FF mode, no noise, never. Furthermore, the noise comes only with a cassette, and once the reels have taken some speed (I can hear the rotation increasing just before the noise comes). I have also tried the following: wihtout a cassette in the well, when I punch very quickly the rewind touch many times, I succeed to get a permanent REWIND motion without a cassette: in these conditions, I do not get the noise! What I am not sure about: is it possible to remove F14 (Fig 2.9, page 10 from the Serv. Manual) from the front cassette well, without dissaembling again the transport? if yes, how? just by pulling it out? I think if it is possible, I should be able to put a tiny drop of ligth oil on the shaft itself) N.B: when reassembling the ideler reel after tire exchange, I put a drop of ligth oil on the shaft odthe idler reel, could it be the reason of the noise?

The service manual says no lubrication is required, except when parts are changed. Then, they recommend 'FLOIL TS-1', made by Kanto Chemicals Co. Ltd. in Japan (where else). Once you get it, apply to the reel hub shaft (after disassembly, of course). I wouldn't get any lubricant on the back tension parts. See the service manual for the exploded view.

But simply listening close to the cassette well cannot tell the difference between one on the reel hubs and the idler hub. I do think that my mistake was to put a tiny little drop of ligth oil on the idler shaft. I think this could be the explanation of the noise that comes only at high rotation speed Now, why the noise does not appear in fast foward? actually, sometimes , it does for the last two seconds, at the very end of the cassette (if you consider that a complete fast foward lasts about 1 minute). Whereas for the complete rewind, it lasts about 30 seconds (half of the time, at least) Only one way to know, diassemble again, clean the idler centre and the idler shaft with hexanes to make sure to remove all oil trace. I 'll try that ASAP...but the music is so nice to listen with this deck... By the way, I noticed that the 2 rubber parts employed to stop the reel rotation (the "brakes" device??) are quite old. Can they be replaced? where can I find two spare one? Bernard Ron a écrit : > > Seems to me, the first order of the day is to locate the > exact source of the noise.

Message-ID: <49B51A80.9010209@yahoo.ca> Hi all, I currently have two BX-2 and one CR-1 decks, and got the two donor CR-1s on Naktalk. One BX-2 works without problems, but the other, with gear drive and circuit mods, never worked properly. It has every common Sankyo problems, and the case cover isn't in great condition. I'll probably pull out the gear drive part and install in the CR-1A transport, as that's apparently the only missing thing, but since they have the same transport, should I build a working CR-1 or BX-2? The BX-2 is made in Japan, has a digital counter, and a headphones volume control. The CR-1 has a better-looking front panel, a shielded transformer, but is lighter, made in Taiwan and doesn't have the extra features from the BX-2 that I've listed. As for the electronics part, is one of them better than the other?

Pin 2 is the center point and pins 1 and 4 are the two legs. Try connecting 1 to 2 and see what happens, then connect 3 to 2 and check. It's possible that the order is somehow different on the transport you're using - especially since the schematic has an error at that point.

I might land one in a few days time and wonder if there are any pointers for faulty lasers - its coming to me as 'untested and might be working fine'. I believe they had a very good build quality and were built in China around 2000. I also believe all the music bank kit had the same loading mechs and that part does not create many issues - at most a belt or two which I assume would not be hard to locate if needed. This would leave the laser as a possible concern. As ar as I know it has no remote with it. I have found snippets on the web but no dedicated site such as ours so pointers or sharing most welcome.

Message-ID: <10367748.1236779847304.JavaMail.root@elwamui-polski.atl.sa.earthlink.net> Record azimuth is adjusted on all decks, with the exception of the Dragon, and the manual knobs on the CR7,TapeDeck 1, 700/1000+II, TD500,700. Having a manual playback azimuth adjust is useful if your tapes come from other sources, like pre-recorded and tapes traded with friends. Self recorded tapes are always optimised for that deck's azimuth (assuming it is properly aligned to ITSELF), however that alignment is only as good(perhaps as correct) as the factory or service person's alignment tape. Azimuth test tapes do have differences! The beauty of the Nakamichi tapes is that the differences were very small. Many cheap alignment tapes use 10 or 12 kHz frequencies, which are simply too low for accurate azimuth alignments of Naks. Think of play azimuth as a reference, a beginning point where all other adjustments and alignments flow from. If azimuth cannot be properly set, every alignmnet following will contain some error. Remember, set the play azimuth to detent when recording! tom brucker -----Original Message----- >From: boitrel >Sent: Mar 11, 2009 4:54 AM >To: Talk about Nakamichi Cassette Decks >Subject: [naktalk] which angle is changed during azimuth tuning? > >I need some help about azimuth: > >- On ZX7: the manual calibration consists of azimuth, level and then >bias tuning? which angle is optimized by the azimuth process? that of >the record head? that of the playback head? or both ? > >- On CR7: the above mentionned procedure is automatic, and represents >the same tuning, I guess.

I have an RM-7C that I bought when I had a CR-7. It's not pristine, there is a crack in the case but it's not falling apart and it does work. Since I no longer have a CR-7 I'd be willing to sell this to a Forum Member. I honestly have no idea what it's worth although I have no delusions that it's worth $600. I'll take bids in a sort of "silent auction" starting today and ending at 11:59 PM, Saturday, March 14. This should be enough time for anyone interested to bid. I'll acknowledge all bids received so you know they've reached me. I'll take a couple of photo's that I can send if requested but I have to warn you that they will be large, 1.5 to 2.5 MB each.

I dont recall posts about these non tape objets. I might land one in a few days time and wonder if there are any pointers for faulty lasers - its coming to me as 'untested and might be working fine'. I believe they had a very good build quality and were built in China around 2000. I also believe all the music bank kit had the same loading mechs and that part does not create many issues - at most a belt or two which I assume would not be hard to locate if needed. This would leave the laser as a possible concern. As ar as I know it has no remote with it. I have found snippets on the web but no dedicated site such as ours so pointers or sharing most welcome.

Now, let's consider the case of ZX7: when turning the azimuth knob, do I change the angle of both heads (R & PB) via the azimuth wire? does the phase comparator compare the phase between recording and playback signals? bernard Tom Brucker a écrit : > Record azimuth is adjusted on all decks, with the exception of the Dragon, and the manual knobs on the CR7,TapeDeck 1, 700/1000+II, TD500,700. > Having a manual playback azimuth adjust is useful if your tapes come from other sources, like pre-recorded and tapes traded with friends. Self recorded tapes are always optimised for that deck's azimuth (assuming it is properly aligned to ITSELF), however that alignment is only as good(perhaps as correct) as the factory or service person's alignment tape. Azimuth test tapes do have differences! The beauty of the Nakamichi tapes is that the differences were very small. Many cheap alignment tapes use 10 or 12 kHz frequencies, which are simply too low for accurate azimuth alignments of Naks. Think of play azimuth as a reference, a beginning point where all other adjustments and alignments flow from. If azimuth cannot be properly set, every alignmnet following will contain some error. > Remember, set the play azimuth to detent when recording! > > tom brucker > > -----Original Message----- >> From: boitrel >> Sent: Mar 11, 2009 4:54 AM >> To: Talk about Nakamichi Cassette Decks >> Subject: [naktalk] which angle is changed during azimuth tuning? >> >> I need some help about azimuth: >> >> - On ZX7: the manual calibration consists of azimuth, level and then >> bias tuning? which angle is optimized by the azimuth process? that of >> the record head? that of the playback head? or both ? >> >> - On CR7: the above mentionned procedure is automatic, and represents >> the same tuning, I guess.

The zx7,zx9zxl,670-682 series decks all have record head azimuth adjustments. The zx7 and zx9 are manually adjusted as is the 680s. The other decks mentioned above have an auto record head adjustment done by a microprocessor aided motor. The playback head on such machines are aligned to the magic azimuth reference point with tapes and gauges. While recording, the record head is angled (manually or automatically) to be in phase with the playback head! 2. The Cr series, the Dragon and the Cassette deck 1 and the Dr1 have playback head azimuth adjustment, automatic on the Dragon implemented by NAAC and manual on the others while playing back and automatic on the Cr7 while calibrating. NAAC i automatic and will not accept ny manual input. The Cr system is automatic for recording and manual while playing back. The record heads in these machines are aligned, fixed by various guages and tapes. The playback heads are the floaters here. Bernard, one of the heads(re or pb) has to be fixed at a reference point and the other has to be adjustble. Both, if made adjustable, will lose a reference point thus killing the advantage of azimuth adjustment itself and will render the deck only good for playing back on itself, if so. I hope this erases any confusion of azimuth adjustments in various Naks. If I have made an error pleas correct me.

In summary: on ZX7, PB head tuned at the magic azimuth and manual azimuth tunes the R head on cr7, R head tuned at a fixec factory azimuth, and one can play with PB head (either automatically before recording, or manually via the knob for reading). Seems to me that this case is better as you can adjust the playback to another tape recorded on another machine?

In other words, during recording calibration the PB is considered fixed and the recording head floats.

I didn't try to extract the shaft, commutator...completely, as it seems to be linked to the outer casing by a spring that just let me perform the cleaning. Is it possible to unhook that spring in some way and take out all the innards ? I suppose so as some posts suggest spinning it with a dremel tool and that can be done only with the shaft and armature extracted from the motor ? 2 - the control motor : Ron, Antoine, Tom.....and others (correct me if I'm wrong) state that refurbishing this one is easier. Well, I had to use the contact cleaner-spraying method on my BX150, until now that has been working, but I would prefer dismantling and doing things right. Here, two problems: how do you take the end-cap off, as that seems more difficult than on the reel motor? It's plastic and I can't guess how it is attached to the metal casing. Then you have to pull off the wormgear from the shaft, and that looks a bit tricky too, as it seems to be quite tight.

As for the worm gear, pry it off with long-nose pliers between the motor's casing and the gear. To put it back, push it in until it can't go further. NOTE: Only push it in the direction you want it to go to, never pull it. Reel motor: 100% success rate refurbishing reel motors so far. If you have a little trouble pulling out the armature, it's absolutely normal as there are magnets in the outer casing. Of course, all the gear drive components have to be removed first, while the backplate can be removed without disassembling anything else. Following is an e-mail I posted in June 08. (Minor revisions done) Antoine --------------------------- Hi all, I thought I'd put out a list of DO's and DON'T's after successfully fixing the dead spots on my second drive motor, which got my recently bought CR-3A working very well (except for the high W&F, due to what seems to be an overtight capstan belt). I already read that the success rate is quite low when burnishing these motors, but there are a few possible explanations to this. DO's: - Place a mark on the bottom cover and casing. You will need to align them back when reassembling the motor : If the back cover is not set back to the original position, the motor will either not run at full strength (or not at all) or the polarity will be reversed. I found that the position had an actual effect when I cleaned the cam motor previously in a BX-2. I marked the polarity on the back cover, and I placed it backwards when reassembling it, and the polarity was reversed! The fact is that the position of the brushes seems to relate to the magnetic fields of the magnet found in the motor casing. Hence the reversed polarity and loss of strength when they're not aligned properly. This was a real problem when I recently rebuilt the drive motor in my CR-3. The motor would barely run, which is when I remembered about the BX-2's cam motor sudden polarity change. I tried to place the back cover on the original marks and it instantly worked beautifully. That's why the cam motor is easy to rebuild : It only has two different possible cover positions, while they are infinite on the reel motor. - Use a quite fine sanding paper when burnishing the commutator : 1000 to 2000 grit, for example. Using a drill attached to the armature shaft will make burnishing a quite easy task. - Remove the black gunk on the brushes. Use 1000 to 2000 grit paper there too. - Make sure, when you place and remove the bottom cover, that the little nylon ring doesn't get stuck on the brushes. They can bend easily - You can use a flat blade screwdriver to remove the back cover. When you put it back, align it, and just push down to clip it back. - When you put back the idler or gear drive components, make sure that the bottom spring holder isn't touching the motor housing, this will otherwise cause friction. DON'T's: - Don't tighten the drill too tight on the shaft, you might damage the shaft. - If your drill has brakes, don't release the button too fast, the armature could fly away. (Talking from personal experience) - Don't put grease in there, you're VERY likely to put some on the brushes or commutator and the motor will not work. (It will work for a few turns and you will instantly get back the three black traces on the commutator and brushes. You can use a few drops of oil, but don't get it on the brushes and commutator. These are the two parts you want to be clean. - Don't forget which part of the idler / gear assembly goes where when you remove it. Take a picture first if necessary. These are the considerations to take when cleaning the drive motors. I've successfully fixed four Sankyo-based Naks this way (oddly, all using gear drive).

I think will work fine, but I haven't actually tried to install one for a control motor. (BTW, I did install one as a reel motor and it worked well, though REW and FF got slightly slower.) I do know that the mounting holes distance is slightly different, so they will have to be slotted or enlarged. This 'project' is on the back burner. When I get a round tuit, I will post the result. -- Ron > > Best regards to all, it's a Great Forum ! -------------- next part -------------- An HTML attachment was scrubbed...

Self recorded tapes are always optimised for that deck's azimuth (assuming it is properly aligned to ITSELF), however that alignment is only as good(perhaps as correct) as the factory or service person's alignment tape. Azimuth test tapes do have differences! The beauty of the Nakamichi tapes is that the differences were very small. Many cheap alignment tapes use 10 or 12 kHz frequencies, which are simply too low for accurate azimuth alignments of Naks. Think of play azimuth as a reference, a beginning point where all other adjustments and alignments flow from. If azimuth cannot be properly set, every alignmnet following will contain some error. > Remember, set the play azimuth to detent when recording! > >tom brucker > >-----Original Message----- >>From: boitrel >>Sent: Mar 11, 2009 4:54 AM >>To: Talk about Nakamichi Cassette Decks >>Subject: [naktalk] which angle is changed during azimuth tuning? >> >>I need some help about azimuth: >> >>- On ZX7: the manual calibration consists of azimuth, level and then >>bias tuning? which angle is optimized by the azimuth process? that of >>the record head? that of the playback head? or both ? >> >>- On CR7: the above mentionned procedure is automatic, and represents >>the same tuning, I guess.

Message-ID: <20507735.1236866837871.JavaMail.root@elwamui-karabash.atl.sa.earthlink.net> I won't help since my comments make things a bit more complex. Any deck with fixed playback heads is aligned to a reference (master) azimuth tape. The record head is then aligned to that deck's play head. Adjustable record head decks have electronic indicators or automatic motors which indicate or seek the best alignment. The CR7 is an odd hybrid. Play and record heads are aligned as if the play head is fixed. Then, both and indicator AND a motor drive circuit are aligned to display best phase in play and proper azimuth during record. I believe the purpose of the motor is not to dynamically find a proper azimuth, but simply to return the play head to detent, or correct position IF record mode is entered. Even the Dragon, which automatically seeks best play azimuth, is referenced to an azimuth alignment tape, because the automatic circuits are aligned or "taught" what correct azimuth looks like electronically. There is no single deck other than the Dragon that can escape the need to have a reference azimuth tape if for some reason the play azimuth is mechanically altered. tom brucker -----Original Message----- >From: boitrel >Sent: Mar 11, 2009 11:08 AM >To: shantiram2000 at yahoo.com, Talk about Nakamichi Cassette Decks >Subject: Re: [naktalk] which angle is changed during azimuth tuning? > >Ram, > >Many thank's for your reply: things are much more clear in my head now! > >In summary: on ZX7, PB head tuned at the magic azimuth and manual >azimuth tunes the R head > >on cr7, R head tuned at a fixec factory azimuth, and one can play with >PB head (either automatically before recording, or manually via the knob >for reading).

Once again the symptoms: Doesn't record. Playback is with a hum and the NR, both B and C, is disabled. By playing a cassette with the tab intact (or the hole on the cassette housing covered with a tape) hum stops, playback and Dolby return to normal but still no record function. It does erase. I've tried disconnecting the record switch to see if playback became normal. It was the same. Put the original transport back but it's doing the same now with that as well. In any case the two transports are identical. I do not have the schematics for the 480Z unfortunately.

Pin 2 is the center point and pins 1 and 4 are the two legs. Try connecting 1 to 2 and see what happens, then connect 3 to 2 and check. It’s possible that the order is somehow different on the transport you’re using – especially since the schematic has an error at that point. Use just a continuity tester to verify the pin configuration I suggested.

The original has shot tape guides and probably a misaligned head as well. Without having the proper gauges it's a tall order. Like I could probably handle the one guide on the right but only with a properly adjusted head hight which this transport doesn't have. When you say pin 1,2,3 it's from left to right on that big switch which is on the smaller board above the big one, is that correct? And what do you mean by jumpering them? Connect them to what? When it comes to the electronic part of doing these things I'm a litlle lost. And, by the way, why does the NR get cancelled out when I put a cassette in with the tabs out? Peter From: willy at willyhermannservices.com To: naktalk at naks.com Subject: RE: [naktalk] 480z Date: Mon, 9 Mar 2009 15:44:10 -0700 There seems to be an error in the 480Z schematic which shows one leg of the record interlock switch ending up dangling in space. Short of tracking to three connections from the record interlock switch I don’t know how you’re going to solve the problem. On the surface the record logic seems the same on the two machines although it’s on a separate board in to 480Z. You might try removing those three wires from the twelve pin connector (pins 1-3), measuring voltages on those pins and jumpering them manually. Swapping transports is never as straightforward as it seems!

Electronically it seemed ok but the transport had some problems. Belts, idler tire, stuck guides etc. Instead of pulling it apart and changing everything which seemed a lot of work I opted for putting in another transport which had already been overhauled from an old 480. The newly installed transport works fine except the deck doesn't record anymore. A strange phenomenon developed. When I play a cassette with the tab intact it plays back fine. If the tab is taken out, in other words the little lever on the top goes right into the hole so that the tape cannot be erased, I get a lot of hum, bad sound and the dolby goes out. If I lift up this lever by hand (with the cover off and front panel out) it plays back fine and the dolby is back. It will not record either way though.It erases ok. I have resoldered the erase head connecting plug on the PCB which seemed loose and lubricated with deoxit all plugs and connectors including the record switch. If anyone can help me with this I will greatly apperciate it. Thanks Peter Hotmail® is up to 70% faster. Now good news travels really fast. Find out more.

Once again the symptoms: Doesn't record. Playback is with a hum and the NR, both B and C, is disabled. By playing a cassette with the tab intact (or the hole on the cassette housing covered with a tape) hum stops, playback and Dolby return to normal but still no record function. It does erase. I've tried disconnecting the record switch to see if playback became normal. It was the same. Put the original transport back but it's doing the same now with that as well. In any case the two transports are identical. I do not have the schematics for the 480Z unfortunately. Thanks and regards Peter From: willy at willyhermannservices.com To: naktalk at naks.com Subject: RE: [naktalk] 480z Date: Tue, 10 Mar 2009 09:03:54 -0700 Pins 1,2,and 3 of CN-1 are the three connections to the double throw record interlock switch. Pin 2 is the center point and pins 1 and 4 are the two legs. Try connecting 1 to 2 and see what happens, then connect 3 to 2 and check. It’s possible that the order is somehow different on the transport you’re using – especially since the schematic has an error at that point. Use just a continuity tester to verify the pin configuration I suggested. Willy From: naktalk-bounces at naks.com [mailto:naktalk-bounces at naks.com] On Behalf Of Peter Tanner Sent: Monday, March 09, 2009 4:32 PM To: naktalk naktalk Subject: RE: [naktalk] 480z Thanks, Willy, so what you are saying effectively is that I should either put the original transport back or try this process? The original has shot tape guides and probably a misaligned head as well. Without having the proper gauges it's a tall order. Like I could probably handle the one guide on the right but only with a properly adjusted head hight which this transport doesn't have. When you say pin 1,2,3 it's from left to right on that big switch which is on the smaller board above the big one, is that correct? And what do you mean by jumpering them? Connect them to what? When it comes to the electronic part of doing these things I'm a litlle lost. And, by the way, why does the NR get cancelled out when I put a cassette in with the tabs out? Peter From: willy at willyhermannservices.com To: naktalk at naks.com Subject: RE: [naktalk] 480z Date: Mon, 9 Mar 2009 15:44:10 -0700 There seems to be an error in the 480Z schematic which shows one leg of the record interlock switch ending up dangling in space. Short of tracking to three connections from the record interlock switch I don’t know how you’re going to solve the problem. On the surface the record logic seems the same on the two machines although it’s on a separate board in to 480Z. You might try removing those three wires from the twelve pin connector (pins 1-3), measuring voltages on those pins and jumpering them manually. Swapping transports is never as straightforward as it seems! Willy From: naktalk-bounces at naks.com [mailto:naktalk-bounces at naks.com] On Behalf Of Peter Tanner Sent: Monday, March 09, 2009 12:27 PM To: naktalk naktalk Subject: [naktalk] 480z Hi everybody, I have a 480Z which I got sometime ago. Electronically it seemed ok but the transport had some problems. Belts, idler tire, stuck guides etc. Instead of pulling it apart and changing everything which seemed a lot of work I opted for putting in another transport which had already been overhauled from an old 480. The newly installed transport works fine except the deck doesn't record anymore. A strange phenomenon developed. When I play a cassette with the tab intact it plays back fine. If the tab is taken out, in other words the little lever on the top goes right into the hole so that the tape cannot be erased, I get a lot of hum, bad sound and the dolby goes out. If I lift up this lever by hand (with the cover off and front panel out) it plays back fine and the dolby is back. It will not record either way though.It erases ok. I have resoldered the erase head connecting plug on the PCB which seemed loose and lubricated with deoxit all plugs and connectors including the record switch. If anyone can help me with this I will greatly apperciate it. Thanks Peter Hotmail® is up to 70% faster. Now good news travels really fast. Find out more.

In-Reply-To: Message-ID: <443723.2422.qm@web30205.mail.mud.yahoo.com> Laser pick-ups can be bought from MCM or similar parts stores. Look for the type number that is etched on the side of the pick up assembly. The number usually starts with a K. I have had no problem locating a new laser for a CD Player 1. Another problem that the player might have is a burnt driver transistor for the pick-up travel motor. Nak cd players have a very nice sound and generally good built. Nakamichi has even OEMed their cd players for big names like McIntosh. The MCD7008 was really a CD Player 4 changer. And Wouter is right - a changer can be addictive! Rgds BG earthrite at gn.apc.org wrote: I dont recall posts about these non tape objets. I might land one in a few days time and wonder if there are any pointers for faulty lasers - its coming to me as 'untested and might be working fine'. I believe they had a very good build quality and were built in China around 2000. I also believe all the music bank kit had the same loading mechs and that part does not create many issues - at most a belt or two which I assume would not be hard to locate if needed. This would leave the laser as a possible concern. As ar as I know it has no remote with it. I have found snippets on the web but no dedicated site such as ours so pointers or sharing most welcome.

It is indeed a Nakamichi CD Player 3/ MB 3 in new clothing. I replaced the belts, aligned the unit and it works like a charm. The CD Player and MB series were very nice machines. They use the Sony KSS-240 laser that has come way down in price since the players were first made. The "MBs" series is another kettle of fish!! Run from those units!!!!! Back in the late '90s when I was still working at a Nakamichi Dealer Service Center they became frequent warranty repairs. They were easily jammed and Nakamichi finally did an upgrade that would shake the drawer to make sure the CD was seated and also added a switch to the CD spindle clamp to make sure that two CDs weren't loaded at once. Nakamichi ran out of service parts for those units quickly. :o( Doug Guth, CTS Field Service Engineer Multi Media Services 1029 Thousand Oaks Blvd. Greenville, SC, 29607 ________________________________ From: Bala Ganesh Chandra [mailto:bg3009 at yahoo.com] Sent: Thursday, March 12, 2009 10:42 PM To: Talk about Nakamichi Cassette Decks Subject: Re: [naktalk] CD Player 3 Music Bank? Laser pick-ups can be bought from MCM or similar parts stores. Look for the type number that is etched on the side of the pick up assembly. The number usually starts with a K. I have had no problem locating a new laser for a CD Player 1. Another problem that the player might have is a burnt driver transistor for the pick-up travel motor. Nak cd players have a very nice sound and generally good built. Nakamichi has even OEMed their cd players for big names like McIntosh. The MCD7008 was really a CD Player 4 changer. And Wouter is right - a changer can be addictive! Rgds BG earthrite at gn.apc.org wrote: I dont recall posts about these non tape objets. I might land one in a few days time and wonder if there are any pointers for faulty lasers - its coming to me as 'untested and might be working fine'. I believe they had a very good build quality and were built in China around 2000. I also believe all the music bank kit had the same loading mechs and that part does not create many issues - at most a belt or two which I assume would not be hard to locate if needed. This would leave the laser as a possible concern. As ar as I know it has no remote with it. I have found snippets on the web but no dedicated site such as ours so pointers or sharing most welcome.

Pin 2 is the center point and pins 1 and 4 are the two legs. Try connecting 1 to 2 and see what happens, then connect 3 to 2 and check. It's possible that the order is somehow different on the transport you're using - especially since the schematic has an error at that point.

Short of tracking to three connections from the record interlock switch I don't know how you're going to solve the problem. On the surface the record logic seems the same on the two machines although it's on a separate board in to 480Z. You might try removing those three wires from the twelve pin connector (pins 1-3), measuring voltages on those pins and jumpering them manually.

Electronically it seemed ok but the transport had some problems. Belts, idler tire, stuck guides etc. Instead of pulling it apart and changing everything which seemed a lot of work I opted for putting in another transport which had already been overhauled from an old 480. The newly installed transport works fine except the deck doesn't record anymore. A strange phenomenon developed. When I play a cassette with the tab intact it plays back fine. If the tab is taken out, in other words the little lever on the top goes right into the hole so that the tape cannot be erased, I get a lot of hum, bad sound and the dolby goes out. If I lift up this lever by hand (with the cover off and front panel out) it plays back fine and the dolby is back. It will not record either way though.It erases ok. I have resoldered the erase head connecting plug on the PCB which seemed loose and lubricated with deoxit all plugs and connectors including the record switch. If anyone can help me with this I will greatly apperciate it. Thanks Peter _____ HotmailR is up to 70% faster. Now good news travels really fast.

Peter From: willy at willyhermannservices.com To: naktalk at naks.com Subject: RE: [naktalk] 480z Date: Mon, 9 Mar 2009 15:44:10 -0700 There seems to be an error in the 480Z schematic which shows one leg of the record interlock switch ending up dangling in space. Short of tracking to three connections from the record interlock switch I don’t know how you’re going to solve the problem. On the surface the record logic seems the same on the two machines although it’s on a separate board in to 480Z. You might try removing those three wires from the twelve pin connector (pins 1-3), measuring voltages on those pins and jumpering them manually. Swapping transports is never as straightforward as it seems! Willy From: naktalk-bounces at naks.com [mailto:naktalk-bounces at naks.com] On Behalf Of Peter Tanner Sent: Monday, March 09, 2009 12:27 PM To: naktalk naktalk Subject: [naktalk] 480z Hi everybody, I have a 480Z which I got sometime ago. Electronically it seemed ok but the transport had some problems. Belts, idler tire, stuck guides etc. Instead of pulling it apart and changing everything which seemed a lot of work I opted for putting in another transport which had already been overhauled from an old 480. The newly installed transport works fine except the deck doesn't record anymore. A strange phenomenon developed. When I play a cassette with the tab intact it plays back fine. If the tab is taken out, in other words the little lever on the top goes right into the hole so that the tape cannot be erased, I get a lot of hum, bad sound and the dolby goes out. If I lift up this lever by hand (with the cover off and front panel out) it plays back fine and the dolby is back. It will not record either way though.It erases ok. I have resoldered the erase head connecting plug on the PCB which seemed loose and lubricated with deoxit all plugs and connectors including the record switch. If anyone can help me with this I will greatly apperciate it.

Why not bad transistor or resistor? Or, PCB track, for that matter; or diode, or IC or contact or relay or anything else? The whole idea behind troubleshooting (which is what I suggested) is to locate the bad component. To effectively troubleshoot this kind of a problem you need the service manual, a signal tracer and the knowledge to use both. The 'signal tracer' is a small amplifier and speaker in a box, whose input is connected to a probe. You touch the probe to the audio output while playing a cassette and hear from its speaker, I assume, hum. You then move the probe back in the signal path, point by point, until you reach a point where the hum disappears. Presumably, this is just before where the hum originates. Or, you apply a signal to the record input of the deck, then touch the signal tracer probe to the next point in the record signal path. You continue probing the record signal path until the signal disappears. That would be just after the problem area. Get the idea? Armed with the proper tools, I'll bet the fault can be found -- maybe even corrected -- in way less time that it took you and Willie to write up your posts. -- Ron -- Ron Peter Tanner wrote: > Thanks, but how do you do that?

For all of our future reference, the winning bid for it was $62.00. When I decided to sell this, I didn't have any idea what it was worth, and ridiculous prices like the $600.00 listing on eBay don't help to clarify things much. So, anyway, I consider $62.00 for a not perfect but working example to be a satisfactory price as far as I as a seller am concerned and I hope that the buyer is satisfied also.

Dolby, bias , and other circuits may be changed. In my experience, replacing orange caps has this priority: Bias = always Dolby= any intermittent noises, or preventative "the bad one"= any specific problem. Replace the other channel if applicable. replace all orange caps= full rebuild. Consult NakTalk for the models which do/do not suffer from orange cap problems. BTW there is an orange cap on the ZX9 capstan motor board which should be changed. tom brucker -----Original Message----- >From: kannan srinivasaraghavan >Sent: Mar 15, 2009 7:59 AM >To: Talk about Nakamichi Cassette Decks >Subject: Re: [naktalk] Orange caps - listings > > >I do not recalll any issues with RX 505 caused by Orange caps and replacing caps infact will cause new issues if not carefully done.

I have checked every single component on the OSC Board replaced the 4081 AND Gate IC as well as both the 4558 and 4559 op amps and checked every single components or the REC Dolby NR Board and everything check outs fine! I am coming to the conclusion that the input signal getting mute from the line imputs once the OSC board is pluggeg in the mother board has got nothing to do with the it, and it seems l this problem seems to be in A B C D tape memory settings , in the RAMM part or even in the auto cal section . I think if you replace the capacitors very carefully with exact same type, value and voltage rating it should not make any difference in the original settings in fact it should make the deck perform better! which might result in higher output level which can easily be adjusted with pots. The old caps change in value you wont believe it how much they have changed in value unless you take the cap out and measure with a meter at capacitance setting. Thanks!

I'll put in my two pennies worth. In my 37 years of repairing electronic equipment, I have very rarely had to change a capacitor, except electrolytics. As for a blanket change of components, in this case orange capacitors, this is as far as I am concerned doomed for disaster. I have had to repair numerous pieces of equipment, after someone before me has tried to find the fault, by changing multiple components. I usually end up repairing the man made faults first, before I can repair the original fault. In conclusion therefore if it is not a well known stock fault eg: the orange capacitors mentioned in Tom's reply to this subject, leave well alone.

Yet, I don't see people replacing any other components en-mass (except maybe tubes -- and for much better reasons). . Note that you advocate replacing *all* film caps. Yet, when asked what you base this expert opinion on, you talk about a single example of one electrolytic that blew when you improperly brought up after years of non-use..What does this have anything to do with the original discussion? Just for the record, over the years I have replaced far moire electrolytic than film caps. > this is a know fact I am surprised you being an engineer dont know it! Do keep the snide remarks to yourself, this is not a pissing contest. You started by claiming (incorrectly) that replacing all film caps improves performance and now support it with a single example of a failed electrolytic and, based on that, you decide I don't know that electrolytics can dry??? Are you serious? I'm done talking to you. -- Ron > > In a message dated 3/17/2009 4:38:22 A.M.

I did replace it with a higher value, following a Heathkit mod , I had a tube amplifier that I brought from someone when I was first getting in the hobby that blew old large electrolytic capacitors the moment it was connected to ac line and power turned on I did not have a variac at that time to slowly power it up! As anyone will tell you many if not all electrolytic capacitors change over the years the chemical paste dries up Sure, it happens. Electrolytics can go bad, so can any other component. Yet, I don't see people replacing any other components en-mass (except maybe tubes -- and for much better reasons). . Note that you advocate replacing all film caps. Yet, when asked what you base this expert opinion on, you talk about a single example of one electrolytic that blew when you improperly brought up after years of non-use..What does this have anything to do with the original discussion? Just for the record, over the years I have replaced far moire electrolytic than film caps. this is a know fact I am surprised you being an engineer dont know it! Do keep the snide remarks to yourself, this is not a pissing contest. You started by claiming (incorrectly) that replacing all film caps improves performance and now support it with a single example of a failed electrolytic and, based on that, you decide I don't know that electrolytics can dry???

If you buy 10 capacitors, all marked with the same value, it's highly unlikely any two of them will have the exact same value. In addition, it's highly unlikely any two of them will exactly track temperature changes. Bottom line: replacing some capacitors will definitely require (at least some) recalibration. in fact it should make the deck perform better! And why is that? Unless the replaced capacitor was bad, you replaced one good capacitor with another (hopefully) good capacitor. Best case, there will be no change in performance. In fact, replacing a good capacitor will never make the deck perform better, though it may make it worse. which might result in higher output level which can easily be adjusted with pots. Capacitors affect frequency response, not level. The old caps change in value you wont believe it how much they have changed in value unless you take the cap out and measure with a meter at capacitance setting. Actually, I have done this many, many times (and I do have the required measuring instruments, including digital capacitance meter, capacitance bridge and ESR meter). I restore vintage test instruments as a hobby, I take a unit apart and completely disassemble it, down to the last resistor, capacitor, screw, nut and bolt. I then check each and every component, repair or replace as necessary. I have found that many capacitors are generally good, even after 30 years of service. For example, I have just finished a complete rebuild of a Heathkit VTVM (manufactured in the early 50s). All (100%) capacitors were still good. All (100%) resistors were out of spec -- some, dramatically so. I wonder where you got the data that implies "caps change in value you wont believe it how much they have changed in value", what tools you own to validate this claim and how many hundreds of capacitors you have tested to make such a sweeping statement. -- Ron Ali In a message dated 3/16/2009 11:56:41 A.M.

I should have been more clear! in my last few posts. The capacitors I replaced on the boards in my 700zxl were the orange poly propylene capacitors know to fail in this machine and the electrolytic capacitors not the other film, mylar and disc type of capacitors which rarely fail . Tom in your latest post you talk about orange mylar capacitors did you meant the orange poly proplyene(pp) caps or are these different from those and what board are they located on. Thanks!

If you buy 10 capacitors, all marked with the same value, it's highly unlikely any two of them will have the exact same value. In addition, it's highly unlikely any two of them will exactly track temperature changes. Bottom line: replacing some capacitors will definitely require (at least some) recalibration. in fact it should make the deck perform better! And why is that? Unless the replaced capacitor was bad, you replaced one good capacitor with another (hopefully) good capacitor. Best case, there will be no change in performance. In fact, replacing a good capacitor will never make the deck perform better, though it may make it worse. which might result in higher output level which can easily be adjusted with pots. Capacitors affect frequency response, not level. The old caps change in value you wont believe it how much they have changed in value unless you take the cap out and measure with a meter at capacitance setting. Actually, I have done this many, many times (and I do have the required measuring instruments, including digital capacitance meter, capacitance bridge and ESR meter). I restore vintage test instruments as a hobby, I take a unit apart and completely disassemble it, down to the last resistor, capacitor, screw, nut and bolt. I then check each and every component, repair or replace as necessary. I have found that many capacitors are generally good, even after 30 years of service. For example, I have just finished a complete rebuild of a Heathkit VTVM (manufactured in the early 50s). All (100%) capacitors were still good. All (100%) resistors were out of spec -- some, dramatically so. I wonder where you got the data that implies "caps change in value you wont believe it how much they have changed in value", what tools you own to validate this claim and how many hundreds of capacitors you have tested to make such a sweeping statement. -- Ron Ali In a message dated 3/16/2009 11:56:41 A.M.

The CR-7A has the record EQ update as well as gear drive reel hub modification. The Dragon is stock. I think the results are stellar, as far as cassette decks go. The test details and results are at the URL below. Have a look: http://www.amb.org/rmaa/nakamichi/cr7a_dragon_tests.html Aside from the Dragon's slightly wavier bass response (probably due to its head geometry), the two decks measured remarkably close in all aspects. Especially noteworthy is the fact that both decks attain flat-to-20KHz response even at 0dB. Whether with Dolby off or on, B or C. None of my other non-Nak decks could get even close to this level of performance. I also included a few "Source-Monitor" measurements as a baseline, and it shows that the sharp rolloff above 20KHz is built-in (i.e., not a limitation of the record or playback head, etc). Nakamichi probably chose to aggressively remove "out of band" signals so that they do not use up tape headroom and cause increased distortion. The rising stereo crosstalk above the midrange is also present in the source-monitor graphs, most probably due to the recording level control pots and the bundles of wires running around. I did not include the THD and IMD graphs because the results are mostly masked by noise that they're largely meaningless.

One example is as Tom Brucker mentioned about caps in the bias trap section.

Ben has done some excellent work on compiling orange caps list for the various decks including the rating and types. Follow this, and get the deck working first. When you have a deck that meets manufacturer's specs with the original (or close to original) components, then it's time to swap, change and tweak. It is very easy to get carried away and start tweaking because yes, there is so much room to do so in a 25 to 30 year old piece of gear. But what is important is to get it working first.

I did replace it with a higher value, following a Heathkit mod , I had a tube amplifier that I brought from someone when I was first getting in the hobby that blew old large electrolytic capacitors the moment it was connected to ac line and power turned on I did not have a variac at that time to slowly power it up! As anyone will tell you many if not all electrolytic capacitors change over the years the chemical paste dries up Sure, it happens. Electrolytics can go bad, so can any other component. Yet, I don't see people replacing any other components en-mass (except maybe tubes -- and for much better reasons). . Note that you advocate replacing all film caps. Yet, when asked what you base this expert opinion on, you talk about a single example of one electrolytic that blew when you improperly brought up after years of non-use..What does this have anything to do with the original discussion? Just for the record, over the years I have replaced far moire electrolytic than film caps. this is a know fact I am surprised you being an engineer dont know it! Do keep the snide remarks to yourself, this is not a pissing contest. You started by claiming (incorrectly) that replacing all film caps improves performance and now support it with a single example of a failed electrolytic and, based on? that, you decide I don't know that electrolytics can dry???

If you buy 10 capacitors, all marked with the same value, it's highly unlikely any two of them will have the exact same value. In addition, it's highly unlikely any two of them will exactly track temperature changes. Bottom line: replacing some capacitors will definitely require (at least some) recalibration. in fact it should make the deck perform better! And why is that? Unless the replaced capacitor was bad, you replaced one good capacitor with another (hopefully) good capacitor. Best case, there will be no change in performance. In fact, replacing a good capacitor will never make the deck perform better, though it may make it worse. which might result in higher output?level which?can easily be adjusted with pots. Capacitors affect frequency response, not level. The old caps change in value you wont believe it how much they have changed in value unless you take the cap?out and measure with a meter at capacitance setting. Actually, I have done this many, many times (and I do have the required measuring instruments, including digital capacitance meter, capacitance bridge and ESR meter). I restore vintage test instruments as a hobby, I take a unit apart and completely disassemble it, down to the last resistor, capacitor, screw, nut and bolt. I then check each and every component, repair or replace as necessary. I have found that many capacitors are generally good, even after 30 years of service. For example, I have just finished a complete rebuild of a Heathkit VTVM (manufactured in the early 50s). All (100%) capacitors were still good. All (100%) resistors were out of spec -- some, dramatically so. I wonder where you got the data that implies "caps change in value you wont believe it how much they have changed in value", what tools you own to validate this claim and how many hundreds of capacitors you have tested to make such a sweeping statement. -- Ron ?

As any engineer knows, different production runs often use different sources for generic components such as caps.

This must have been a time consuming task, but the results are illuminating I found your work exceedingly interesting. Almost 10 years ago I ran informal listening tests on the two models. I found the Dragon sound a bit 'looser' and 'warmer' than the crystal clear CR-7. The difference was very subtle and subdued, but always there (I listened to several samples of each deck, but at different times and locations, and with different sound systems). Looking at your graphs, I now suspect I understand where that sonic difference came from. Most revealing are the REC/PB noise curves. Seems your Dragon (possibly, every Dragon) has pronounced 60Hz hum (this is also visible in the monitor noise). To a lesser extent, so does your CR-7, but the Dragon shows a large number of harmonics, which the CR-7 doesn't. Perhaps, this explains the difference I heard between the two. Based on the price difference, coupled with the sonic difference, I finally chose a CR-7. Had I had you graphs in front of me at the time, that decision would have been an easier one. I wonder if you could eliminate the hum and its harmonics in the Dragon -- a worthwhile exercise, whether the hum is design related or just an artifact in your particular Dragon sample. Probably, replacing the rectifiers with fast recovery diodes, increasing values of filter caps and bridging them with film caps will do it. This may subjectively 'purify' the Dragon sound (or not -- the only proof of this particular pudding is in the eating :_) ).

I haven't found a Nak deck recording flat at 0Vu at 20kHz ever, so I will recheck my own observations. From Ram's 1000ZXL test recording 20Khz was flat up to -8Vu with MX tape. The ZXL record/play response was 33.5kHz at -20, indicating that the "hard" input filter was removed in these decks. The bass response observed in the Dragon is indeed a result of the narrower Face of the play head. These are called "head bumps" , believe it or not. I am curious about the spikes observed in the Dragon noise tests. Your Dragon may have orange cap problems with the Dolby caps. These commonly make shooting or rushing type noises masked by the audio. I'd be curious to compare L/R channel performance between the two decks. -----Original Message----- >From: Ti Kan >Sent: Mar 18, 2009 12:24 AM >To: naktalk at naks.com >Subject: [naktalk] My CR-7A and Dragon bench tests > >Hi all, > >I ran some bench tests on my CR-7A and my Dragon.

Nashville, TN 37211 hitech77 at earthlink.net hitech at bellsouth.net 615-331-9241 From johngipps at aol.com Wed Mar 18 19:02:00 2009 From: johngipps at aol.com (johngipps at aol.com) Date: Wed, 18 Mar 2009 14:02:00 -0400 Subject: [naktalk] My CR-7A and Dragon bench tests Message-ID: <8CB760AC4DAA276-1384-4107@webmail-mf16.sysops.aol.com> Hi Ti You have obviously put a lot of time and effort into your response measurements, and your graph data is nicely presented. Unfortunately, your results show your CR-7 and Dragon to be considerably better than Nakamichi claimed them to be, and your responses at 0dB are in disagreement with Nakamichi published data, and with my own measurements, and those of others. I say this in the kindest way, and urge you to go back and check your test procedures, and in particular, your recording levels. Your responses at a recording level of 0dB (defined by Nakamichi as 200nW/m), show your CR-7 and Dragon as achieving essentially the same responses with Dolby C, Dolby B, and Dolby off. This is simply not the case. At a recording level of 0dB, a healthy CR-7 or Dragon will achieve a frequency response of typically 13KHz with Dolby B On or Dolby Off, and typically 21KHz with Dolby C on. If you look at Nakamichi published frequency responses in either an Owners Manual, or a Sales Brochure, you will see what I'm talking about. These show at 0dB, a Dolby B response typically at -10dB at 20KHZ, and a Dolby C response typically flat to just over 20KHz. At lower record levels, say -20dB, the responses for Dolby B and C are the same, and a little above 20KHz. I wonder if there's a chance that your "0dB" is really somewhat lower than 200nW/m - this would be one explanation for the discrepancies. Once again, I applaud your hard work, and urge you to check your procedures.

The CR-7A has the record EQ update as well as gear drive reel hub modification. The Dragon is stock. I think the results are stellar, as far as cassette decks go. The test details and results are at the URL below. Have a look: http://www.amb.org/rmaa/nakamichi/cr7a_dragon_tests.html Aside from the Dragon's slightly wavier bass response (probably due to its head geometry), the two decks measured remarkably close in all aspects. Especially noteworthy is the fact that both decks attain flat-to-20KHz response even at 0dB. Whether with Dolby off or on, B or C. None of my other non-Nak decks could get even close to this level of performance. I also included a few "Source-Monitor" measurements as a baseline, and it shows that the sharp rolloff above 20KHz is built-in (i.e., not a limitation of the record or playback head, etc). Nakamichi probably chose to aggressively remove "out of band" signals so that they do not use up tape headroom and cause increased distortion. The rising stereo crosstalk above the midrange is also present in the source-monitor graphs, most probably due to the recording level control pots and the bundles of wires running around. I did not include the THD and IMD graphs because the results are mostly masked by noise that they're largely meaningless. Thought you might find this interesting. -Ti -------------- next part -------------- An HTML attachment was scrubbed...

Message-ID: Hi Bala, Great to hear from you again! Please help me with my 700zxl problems it will be much appreciated. This machine has problems that are very baffling here is the list: The machine is not passing input signal from line inputs when you move the tape/source switch to source, the strange thing is that when you switch in the 400hz and tape/monitor switch to source it does pass this signal and recording of this signal is great! but when you turn off the test tone signal and want to monitor the signal from line inputs it will not pass the signal a few beginning segments of the vu meter light up even with the line input turn all the way to zero! turning the round input control and the output monitor control you can hear a very sound the source connected to the line inputs. The strange thing when you raise the OSC Board so that the pins that are marked 400hz/7khz/15kz/line off are not touching the mating holes in the mother board then the line audio pass through crystal clear! and without any distortion but the moment you push the pins back in the audio again get muted to the state described above. I have checked every transistor/diode and even every single electrolytic capacitors on ALL! The boards including those on THE RAMM, THE SANDWICH AUTO CAL A&B Boards every single of these components check out great. I even replaced the 4558 , 4459 op amps and the 4081 CMOS IC on the OSC Board but it made no difference. I even traced the line off circuit from the OSC Board to REC Dobly NR Board all the components in this circuit checked out just fine! I am beginning to think the problem is either lies in the tape memory part , the auto cal or in the RAMM part as I see there is line mute circuit on the main logic board connected to the auto calibration boards. Also like to mention that when you do auto cal the machine does perform auto cal for a breif period for maybe just 3 or 3 second rewind and the counter reset to 0000 but the auto azimuth light does not light up in the process. Also another problem is that the tape display for EX, SX, ZX stay lit all the time moving the tape selector to ex, sx, and zx makes no difference, only when you perform the auto cal will the lights go out and the one you have selected light up but this again reverses if you perform fast forward or rewind. The items that are working on this tape decks are : AWESOME PLAYBACK! for which this and 1000zxl are famous even with the auto cal not functioning fully. The 400 hz test tone works and the recording takes place in both channel with excellent recording quality in both channel and with correct balance between right and left channels, but NO! recording is possible from the line inputs because the signal is not passing through as mentioned above. You are kind help as always is greatly appreciated. You are THE EXPERT! on this machine and I know you will know what is wrong with it with the symptons mentioned above. All I almost forgot, since I got so much scolding recently I have reinstalled all the original electrolytic capacitors and the some of the orange caps for which I could not find the exact same value, this machine has really no orange pp caps or electrolytic caps problems the problems I think likes in one or more IC Chips but which one?!! I am sure with your expertise you will recognize what is wrong to being causing the problems above rightaway since you have one most experienced on these 700ZXE, 700ZXL AND THE 1000ZXL.

Firstly, any perception that en lot replacement of capacitors is going cure ailments is wrong. If the deck is diagnosed in having a number of orange caps failing, then it is better to change the bad ones as well as the rest as a precaution. But one should not simply change caps and cross their fingers when facing a faulty deck. Second, with the changes in capacitor technology, this is going to be a very open and debatable subject with various members having their own views and favorite brands - which is good! However, when making replacements or modifications, one should understand the application very carefully and then make their choices. One example is as Tom Brucker mentioned about caps in the bias trap section. Thirdly, try to keep within context.When working on a 700ZXL or a 580, concentrate on following what Nakamichi has done originally with the deck. Ben has done some excellent work on compiling orange caps list for the various decks including the rating and types. Follow this, and get the deck working first. When you have a deck that meets manufacturer's specs with the original (or close to original) components, then it's time to swap, change and tweak. It is very easy to get carried away and start tweaking because yes, there is so much room to do so in a 25 to 30 year old piece of gear. But what is important is to get it working first.

If you buy 10 capacitors, all marked with the same value, it's highly unlikely any two of them will have the exact same value. In addition, it's highly unlikely any two of them will exactly track temperature changes. Bottom line: replacing some capacitors will definitely require (at least some) recalibration. in fact it should make the deck perform better! And why is that? Unless the replaced capacitor was bad, you replaced one good capacitor with another (hopefully) good capacitor. Best case, there will be no change in performance. In fact, replacing a good capacitor will never make the deck perform better, though it may make it worse. which might result in higher output level which can easily be adjusted with pots. Capacitors affect frequency response, not level. The old caps change in value you wont believe it how much they have changed in value unless you take the cap out and measure with a meter at capacitance setting. Actually, I have done this many, many times (and I do have the required measuring instruments, including digital capacitance meter, capacitance bridge and ESR meter). I restore vintage test instruments as a hobby, I take a unit apart and completely disassemble it, down to the last resistor, capacitor, screw, nut and bolt. I then check each and every component, repair or replace as necessary. I have found that many capacitors are generally good, even after 30 years of service. For example, I have just finished a complete rebuild of a Heathkit VTVM (manufactured in the early 50s). All (100%) capacitors were still good. All (100%) resistors were out of spec -- some, dramatically so. I wonder where you got the data that implies "caps change in value you wont believe it how much they have changed in value", what tools you own to validate this claim and how many hundreds of capacitors you have tested to make such a sweeping statement. -- Ron Ali In a message dated 3/16/2009 11:56:41 A.M.

As any engineer knows, different production runs often use different sources for generic components such as caps. Bottom line: a cap list made from one deck may -- or may not -- apply to another deck and a cap list compiled from the manual may -- or may not -- apply to all caps in any specific deck. -- Ron Dr. Wolfgang Smetanig wrote: Thank you so much guys for your informations!

In-Reply-To: Message-ID: <196326.46700.qm@web30203.mail.mud.yahoo.com> Hi Ali, I do not have the schematics at hand but here are some key things to consider: The auto-cal system works by using the MSM memory ICs in either memory or pass-thru mode. Thus, if these ICs are shot, then the auto-cal system is not going to work. If you have replaced the rest of the semi-conductors with known working parts, then the memory ICs are the last item left on the list. The first important half is that the deck plays back. This it seems to do and that is great.From your descriptions, the auto-cal PCB and the main logic PCB that houses the switching circuits and auto-azimuth circuit needs some work. The transport controls and playback board seem to be working at the moment. You also don't want to take apart and start soldering and desoldering too many things because these decks are not exactly built for longevity. So avoid stressing connectors and contact points too much. Come back to you. Rgds, BG BOEING747600 at aol.com wrote: Hi Bala, Great to hear from you again!

Actually, I have done this many, many times (and I do have the required measuring instruments, including digital capacitance meter, capacitance bridge and ESR meter). I restore vintage test instruments as a hobby, I take a unit apart and completely disassemble it, down to the last resistor, capacitor, screw, nut and bolt. I then check each and every component, repair or replace as necessary. I have found that many capacitors are generally good, even after 30 years of service. For example, I have just finished a complete rebuild of a Heathkit VTVM (manufactured in the early 50s). All (100%) capacitors were still good. All (100%) resistors were out of spec -- some, dramatically so. I wonder where you got the data that implies "caps change in value you wont believe it how much they have changed in value", what tools you own to validate this claim and how many hundreds of capacitors you have tested to make such a sweeping statement. -- Ron Ali In a message dated 3/16/2009 11:56:41 A.M.

Message-ID: Hi Bala, Thanks for your kind email, I look forward to your further ideas and suggestions with the problems mentioned in the last post. Also like to mention when you try to do auto cal as per the manual by first pressing the record and pause buttons together and then pressing the play button while keeping the run buttom pressed , the green light in the run buttom light up but NOT! in the auto azimuth button next to it , and it seems like its trying to do auto cal the lights start flashing in the auto cal display it does this all very fast for say for maybe only 3 secs! then rewind and the counter get reset to 0000 like it had done a successful auto cal I will again check the light bulb in the auto azimuth to see the filament is ok by looking and taking a resistence reading with my hi-end fluke 189 digital meter. Looking at the schematics in the service manual which is available for free downolad here at naktalk to forum memebers in the archives it shows that the output from the tape selector first goes to the input of a large! IC which I believe is the mini computer or micro processor for the RAMM section also marked RAMM part or port on the schematics . I am eagerly awaiting your kind suggestions to solve the problems with this deck YOU ARE THE MAN! AND THE EXPERT! WHO KNOW THESE MACHINES THE BEST! I am sure with your kind help the problems with this machine will be solved as together with the 1000zxl this is the finest! deck ever produced by Nakamichi. I have put back all the original electrolytic caps that I took out of this machine and even couple of orange pp caps for which I could not get the exact same value rest of the orange pp capacitor have been replaced with exact same value and voltage replaced just to be on the safe side! although the old ones are also ok and as I mentioned previously this particular example of 700ZXL has no bad orange polyproplyene (pp) capacitors in it and all electrolytic capacitors are ok as are all the transistors and diode on each single board I have painstakingly! checked EVERY! Single one of them! MANY THANKS AS ALWAYS!! With Best Regards! Ali In a message dated 3/19/2009 5:56:36 A.M. Eastern Daylight Time, bg3009 at yahoo.com writes: Hi Ali, I do not have the schematics at hand but here are some key things to consider: The auto-cal system works by using the MSM memory ICs in either memory or pass-thru mode. Thus, if these ICs are shot, then the auto-cal system is not going to work. If you have replaced the rest of the semi-conductors with known working parts, then the memory ICs are the last item left on the list. The first important half is that the deck plays back. This it seems to do and that is great.From your descriptions, the auto-cal PCB and the main logic PCB that houses the switching circuits and auto-azimuth circuit needs some work. The transport controls and playback board seem to be working at the moment. You also don't want to take apart and start soldering and desoldering too many things because these decks are not exactly built for longevity. So avoid stressing connectors and contact points too much. Come back to you. Rgds, BG BOEING747600 at aol.com wrote: Hi Bala, Great to hear from you again! Please help me with my 700zxl problems it will be much appreciated. This machine has problems that are very baffling here is the list: The machine is not passing input signal from line inputs when you move the tape/source switch to source, the strange thing is that when you switch in the 400hz and tape/monitor switch to source it does pass this signal and recording of this signal is great! but when you turn off the test tone signal and want to monitor the signal from line inputs it will not pass the signal a few beginning segments of the vu meter light up even with the line input turn all the way to zero! turning the round input control and the output monitor control you can hear a very sound the source connected to the line inputs. The strange thing when you raise the OSC Board so that the pins that are marked 400hz/7khz/15kz/line off are not touching the mating holes in the mother board then the line audio pass through crystal clear! and without any distortion but the moment you push the pins back in the audio again get muted to the state described above. I have checked every transistor/diode and even every single electrolytic capacitors on ALL! The boards including those on THE RAMM, THE SANDWICH AUTO CAL A&B Boards every single of these components check out great. I even replaced the 4558 , 4459 op amps and the 4081 CMOS IC on the OSC Board but it made no difference. I even traced the line off circuit from the OSC Board to REC Dobly NR Board all the components in this circuit checked out just fine! I am beginning to think the problem is either lies in the tape memory part , the auto cal or in the RAMM part as I see there is line mute circuit on the main logic board connected to the auto calibration boards. Also like to mention that when you do auto cal the machine does perform auto cal for a breif period for maybe just 3 or 3 second rewind and the counter reset to 0000 but the auto azimuth light does not light up in the process. Also another problem is that the tape display for EX, SX, ZX stay lit all the time moving the tape selector to ex, sx, and zx makes no difference, only when you perform the auto cal will the lights go out and the one you have selected light up but this again reverses if you perform fast forward or rewind. The items that are working on this tape decks are : AWESOME PLAYBACK! for which this and 1000zxl are famous even with the auto cal not functioning fully. The 400 hz test tone works and the recording takes place in both channel with excellent recording quality in both channel and with correct balance between right and left channels, but NO! recording is possible from the line inputs because the signal is not passing through as mentioned above. You are kind help as always is greatly appreciated. You are THE EXPERT! on this machine and I know you will know what is wrong with it with the symptons mentioned above. All I almost forgot, since I got so much scolding recently I have reinstalled all the original electrolytic capacitors and the some of the orange caps for which I could not find the exact same value, this machine has really no orange pp caps or electrolytic caps problems the problems I think likes in one or more IC Chips but which one?!! I am sure with your expertise you will recognize what is wrong to being causing the problems above rightaway since you have one most experienced on these 700ZXE, 700ZXL AND THE 1000ZXL.

Eastern Daylight Time, bg3009 at yahoo.com writes: Hi Ali and everyone else, This seems to be one topic where the more is discussed, the less sense it is beginning to make. Firstly, any perception that en lot replacement of capacitors is going cure ailments is wrong. If the deck is diagnosed in having a number of orange caps failing, then it is better to change the bad ones as well as the rest as a precaution. But one should not simply change caps and cross their fingers when facing a faulty deck. Second, with the changes in capacitor technology, this is going to be a very open and debatable subject with various members having their own views and favorite brands - which is good! However, when making replacements or modifications, one should understand the application very carefully and then make their choices. One example is as Tom Brucker mentioned about caps in the bias trap section. Thirdly, try to keep within context.When working on a 700ZXL or a 580, concentrate on following what Nakamichi has done originally with the deck. Ben has done some excellent work on compiling orange caps list for the various decks including the rating and types. Follow this, and get the deck working first. When you have a deck that meets manufacturer's specs with the original (or close to original) components, then it's time to swap, change and tweak. It is very easy to get carried away and start tweaking because yes, there is so much room to do so in a 25 to 30 year old piece of gear. But what is important is to get it working first.

The capacitors I replaced on the boards in my 700zxl were the orange poly propylene capacitors know to fail in this machine and the electrolytic capacitors not the other film, mylar and disc type of capacitors which rarely fail . Tom in your latest post you talk about orange mylar capacitors did you meant the orange poly proplyene(pp) caps or are these different from those and what board are they located on. Thanks!

As anyone will tell you many if not all electrolytic capacitors change over the years the chemical paste dries up Sure, it happens. Electrolytics can go bad, so can any other component. Yet, I don't see people replacing any other components en-mass (except maybe tubes -- and for much better reasons). . Note that you advocate replacing all film caps. Yet, when asked what you base this expert opinion on, you talk about a single example of one electrolytic that blew when you improperly brought up after years of non-use..What does this have anything to do with the original discussion? Just for the record, over the years I have replaced far moire electrolytic than film caps. this is a know fact I am surprised you being an engineer dont know it! Do keep the snide remarks to yourself, this is not a pissing contest.

If you buy 10 capacitors, all marked with the same value, it's highly unlikely any two of them will have the exact same value. In addition, it's highly unlikely any two of them will exactly track temperature changes. Bottom line: replacing some capacitors will definitely require (at least some) recalibration. in fact it should make the deck perform better! And why is that? Unless the replaced capacitor was bad, you replaced one good capacitor with another (hopefully) good capacitor. Best case, there will be no change in performance. In fact, replacing a good capacitor will never make the deck perform better, though it may make it worse. which might result in higher output level which can easily be adjusted with pots.

This must have been a time consuming task, but the results are illuminating I found your work exceedingly interesting. Almost 10 years ago I ran informal listening tests on the two models. I found the Dragon sound a bit 'looser' and 'warmer' than the crystal clear CR-7. The difference was very subtle and subdued, but always there (I listened to several samples of each deck, but at different times and locations, and with different sound systems). Looking at your graphs, I now suspect I understand where that sonic difference came from. Most revealing are the REC/PB noise curves. Seems your Dragon (possibly, every Dragon) has pronounced 60Hz hum (this is also visible in the monitor noise). To a lesser extent, so does your CR-7, but the Dragon shows a large number of harmonics, which the CR-7 doesn't. Perhaps, this explains the difference I heard between the two. Based on the price difference, coupled with the sonic difference, I finally chose a CR-7. Had I had you graphs in front of me at the time, that decision would have been an easier one. I wonder if you could eliminate the hum and its harmonics in the Dragon -- a worthwhile exercise, whether the hum is design related or just an artifact in your particular Dragon sample. Probably, replacing the rectifiers with fast recovery diodes, increasing values of filter caps and bridging them with film caps will do it. This may subjectively 'purify' the Dragon sound (or not -- the only proof of this particular pudding is in the eating :_) ).

Sometimes, while at the bench, using a T-100, I have switched the freq. to 20KHz, without attenuating to -20dB, and no signal was recorded whatsoever. I really have seriour doubts any cassette deck can record 20KHz at more than -10dB, and that sounds a lot to me!. I strongly believe something is missing here ... With warmest regards, LP.

With either, I use my ears as a final judge, aided by flicking the tape/monitor switch back an forth . -- Ron Roland wrote: > This thought occurred to me the other day when I was doing some rtr recording. > > I have an Otari 5050 that has needle type level meters. > > I have a Dragon that has a bar graph for level recording. > > I once had a CR7A that could do a peak 'n hold. > > All have headphone jacks. > > I'm 53 and long lost my ability to hear 20-20khz and my 20 year old Forte II's, although horned, certainly aren't factory perfect (close though!). > > So, this is my question.

Tom, this is not exactly what I do but along the same idea. The Dragon at 400hz is set to 0db and the 15khz is set to +1db During recording, I set the levels to 1db below the recommended for eah tape type and it works quite well for me. Oddly enough by using this method, the low end TDK Type I D-series tapes can be pushed to a higher than recommended levels. >Roland wrote: > > > This thought occurred to me the other day when I was doing some rtr > >recording. > > > > > > I have an Otari 5050 that has needle type level meters. > > > > > > I have a Dragon that has a bar graph for level recording. > > > > > > I once had a CR7A that could do a peak 'n hold. > > > > > > All have headphone jacks. > > > > > > I'm 53 and long lost my ability to hear 20-20khz and my 20 year old > >Forte II's, although horned, certainly aren't factory perfect (close > >though!). > > > > > > So, this is my question.

Metal tapes on decks which use the pressure pad might cause extra head wear unless there is a Gx glass or  ferrite head( as AKai and SOny used) Metal tapes can be played on non Metal capable decks with an eq of 70Usec position. However, you can not record on these metal tapes if your deck does not have a metal bias setting.( which supplies higher current to the record and erase heads to permeate magnetism to the metal tape) Regards, Ram --- On Sun, 3/22/09, jamiep8 at comcast.net wrote: From: jamiep8 at comcast.net Subject: [naktalk] Metal Tapes To: naktalk at naks.com Date: Sunday, March 22, 2009, 10:47 AM #yiv1613938738 p {margin:0;}I was wondering if anyone might have any thoughts on wheather pro-longed use of metal tapes actually wears heads down?

For playback, it doesn't matter whether your deck is a "metal" deck or a "non metal" deck - these terms only refer to the ability of a deck to record on metal tapes. Every deck can play back a metal tape, and with no harm associated with doing so. I tend to use a lot more non metal tapes than metal ones - I personally don't see a big advantage in metal tape for most recordings. I note you use TDK SA - good tape, but TDK SAX is a lot better, and is still easily available at reasonable prices. It has much lower distortion than does TDK SA, and this translates to (in my opinion) a more open and detailed sound.

However, you can make a couple of educated guesses. First, half the secondary feeds three 14V/80mA lamps through a 10 Ohm/2W resistor. Assuming the lamps are provided with their specified voltage and draw their specified current, the voltage drop across that resistor would be V= I*R = (3*0.08)*10 = 2.4V, so, it would be supplied with (14+2.4) = 16.4VAC. Second, the secondary feeds a couple of full wave rectifiers, each feeding a 12V regulator. Working backward, these regulators (generically -- I do not have the data sheet for the specific one used by Nakamichi) have a drop-out voltage of of 3V, so must be fed by 15V minimum. Assuming filter cap and draw current are such that the DC voltage is 70% of peak AC input to the rectifiers (reasonable ball park figure) and that the rectifiers drop about 1.4V, then the transformer secondary should output (15*1.414*0.7+1.4) = 16.21VAC, under under load. Taking all these assumptions together, a reasonable guesstimate of the secondary requirement is 2 x 16VAC to 2 x 16.5VAC under load. While it's difficult to estimate the full load current, if you can remove the insulation and measure the secondary wire gauge, it will give you a good indication. Be aware of the many assumptions made here... YMMV. Assuming you have the right equipment, though, all this is not necessary -- just feed the deck with variable AC and measure the voltage required to provider at least 3V drop across the positive regulator and resulting in 14V or slightly less across lamps PL001 to PL003. Good luck, -- Ron -------------- next part -------------- An HTML attachment was scrubbed...

According to NR-0056 document, it appears not too diffcult to perform but: 1. Why is it worth to do it? is it correct that the lost in high frequency will appen more with type IV cassettes as MAX TDK for exemple? 2. After the modification, does the deck need re-adjustments? what does mean the ine (13) on page 3 of NR-0056: "perform re-adjustment using new reference apes?" thank's Bernard ------------- next part -------------- n HTML attachment was scrubbed...

Playback head assembly is GA-101, playback head is P-52. Record head assembly is GA-102, record head is R-52. I think that there was no substantial difference between roller assemblies for the 700 and 700II, and that the? heads slowly evolved from the first offerings of R-52 and P-52. >From my memory, the biggest differences between the 700 and 700II transports are in the reel drive mechanisms. In the 700, the capstan motor not only drives the capstans in play mode, but also provides the reel drive via a reel drive mechanism. In FF and REW, the reel motor drives the reels, also via the reel drive assembly. In the 700II, in play mode, the capstan motor only drives the capstans, and the reel motor drives the reels via a ball drive assembly. In FF and REW, the reel motor drives the reels, via the ball drive assembly. I think the roller assemblies and heads changed a little and were improved through the life of the 700/700II program, but that they were not the discerning differences between the 700 and 700II. I think the drive assemblies above more define the difference. It's been a while since I worked on a 700/700II, so I hope the above is accurate.

If this helps, then consider replacement. However, if you don't hear any sound on PB, even for a second or two before it quits, there are other problems. As to selling -- why don't you tell us what you want for it and where you are located. It's always better to deal with friends, rather then strangers. -- Ron Keith Knaggs wrote: > I have a BX-300.

In fact, on some tracks( only on some tracks now) I like its sharpness( and fast paced hurried sound) a tad better than my Dragons'.....only at times, however. It has the same mechanism as the 680-1000ZXL series deck and  the same heads as well.

While testing it I've noticed that when the power comes on the capstan motor starts rotating immediately. In other words the motor always runs with the capstans rotating even before I press the play button. It plays normal once the play button is pressed. I am more familiar with the 480 series where the motor rotates when the play is activated. Is this normal for this deck? All functions and lights are as normal otherwise. Play/record/fastworward etc. Thanks for someone letting me know, especially if it's a fault, how to correct it.

Hi Mark Well I went thru a burst of doing this with a whole raft of tracks extracted from various tapes made over the years - the motive was when my Audi came with cd player rather than tape. In Europe dual media tape/cd players are in my experience rare. Anyway I pop the output straight into a standalone cd recorder so the process can be fairly straightforward avoiding computers and further time etc. My motive wasnt to listen to the individual Nak characteristics but just to enjoy some of the hidden gems on older tapes. However the end results are always very rewarding musically and frequently a source of interest and curiousity to passengers especially when they hear that the source was a home recorded cassette. So I hope you get round to doing this soon and that your new phase of life brings new and rewarding opportunities. Autocad is out of my league but it sounds like a popular project for nak nuts! ian scotland -------------- next part -------------- An HTML attachment was scrubbed...

All decks deemed by Nak as 'high end' had the capstan run continuously. This guaranteed that the capstan motor was stable from the get go. On the con side, this tends to wear the capstan motor sooner.

While testing it I've noticed that when the power comes on the capstan motor starts rotating immediately. In other words the motor always runs with the capstans rotating even before I press the play button. It plays normal once the play button is pressed. I am more familiar with the 480 series where the motor rotates when the play is activated. Is this normal for this deck? All functions and lights are as normal otherwise. Play/record/fastworward etc. Thanks for someone letting me know, especially if it's a fault, how to correct it.   Peter Windows Live™: Keep your life in sync.

The front has a total of 11 shelves. I designed it for the very top and bottom shelf to hold VHS tapes, the 2nd to the bottom shelf to hold cassettes only, and the rest of the shelves to hold either CD's or cassette. The back of the unit has three shelves for storing more media. The height of this unit was designed so I can remove the media from the very top shelf and roll the unit through a doorway to another room by the supplied casters. The very bottom has a secret compartment.

I am more familiar with the 480 series where the motor rotates when the play is activated. Is this normal for this deck? All functions and lights are as normal otherwise.

My repair database backed up my memory of that fault. In Australia, the 680ZX meter failure was incredibly common - but it was never the CMOS chips IC901 and IC902 - it was always an orange cap problem. Coincidentally, the orange caps to replace are C901 and C902 - 4.7nF and 10nF. The capacitor most commonly defective is C901, and C902 is less common. C901 is required in the normal mode of the meter, and C902 is used in cal mode. My database had literally dozens of instances of C901 failure (and none of IC901 and IC902). Good luck with it Kermit.

Hi Kermit and Willy I just went through my Nak repair database, because Willy's suggestion of IC901 and IC902 being likely culprits surprised me. My repair database backed up my memory of that fault. In Australia, the 680ZX meter failure was incredibly common - but it was never the CMOS chips IC901 and IC902 - it was always an orange cap problem. Coincidentally, the orange caps to replace are C901 and C902 - 4.7nF and 10nF. The capacitor most commonly defective is C901, and C902 is less common. C901 is required in the normal mode of the meter, and C902 is used in cal mode. My database had literally dozens of instances of C901 failure (and none of IC901 and IC902). Good luck with it Kermit.

Records well, plays great, calibration works flawlessly (at last!). I forgot that amazing bass sound these machines produce! I'm down to only two problems: Firstly, the meter keep cutting out.

Yes, I have; more than once. Besides, I was specifically referring to the DD Sankyo motor, as in the CR-7, that you objected to. This is an open motor -- no cage at all. I have repaired several of those, no problem. On the capstan motor count, there is reason to avoid MR-1, BX-300, CR-5 or, of course, CR-7. -- Ron > I have and had no luck getting them back together in good working order. > If possible, I would rather just replace them. > > Richard Kern > > > In a message dated 5/7/2009 12:10:46 A.M.

They seem ok. However, I've noticed another thing. When I try to spin the right hub (F14, reel hub take up assembly) by hand towards the rewind direction it is extremely stiff. It spins forward without problem. So perhaps the motor and the idler are trying to pull the take up hub in the rewind direction, and it works for about 20% of the tape to be rewound, but then it slows down. Looks like the hub is too hard to pull so the left reel then starts slipping and eventually goes into the stop mode. I've checked the take up reel and it seemed ok, the belt is new from Fred Marrs, and without the belt on the black shut off sensor disc spins freely. Unless that disc starts sticking once the belt is on or something is braking the whole rewind action, I just can't tell. I have another classic transport I keep as a spare as it used to work really well in a 480 which has defective electronics so I'll change the reels from that one over and see what happens. I have noticed, by the way, that in this transport the idler tire has much more clearance from the supply and take up hubs than the transport in the 582. Perhaps because the tire is much more worn, I don't know, but there is only about a mm from one or the other.

They seem ok. However, I've noticed another thing. When I try to spin the right hub (F14, reel hub take up assembly) by hand towards the rewind direction it is extremely stiff. It spins forward without problem. So perhaps the motor and the idler are trying to pull the take up hub in the rewind direction, and it works for about 20% of the tape to be rewound, but then it slows down. Looks like the hub is too hard to pull so the left reel then starts slipping and eventually goes into the stop mode. I've checked the take up reel and it seemed ok, the belt is new from Fred Marrs, and without the belt on the black shut off sensor disc spins freely. Unless that disc starts sticking once the belt is on or something is braking the whole rewind action, I just can't tell. I have another classic transport I keep as a spare as it used to work really well in a 480 which has defective electronics so I'll change the reels from that one over and see what happens. I have noticed, by the way, that in this transport the idler tire has much more clearance from the supply and take up hubs than the transport in the 582. Perhaps because the tire is much more worn, I don't know, but there is only about a mm from one or the other.

But I do not understand "The motor or rather the idler spins the hub but the outer part which is before that clutch like felt pad is slipping". Looking at Fig. 3.8 of the 582 service manual page 32, are you saying that part F13 is slipping on part F15? If so, check these parts for wear (there should be none) and check the felt pad part F16 and spring F17 for correct seating. Parts F13 and F15 should not be able to slip w.r.t each other. Also, when pushing part F13, it should move in easily, but immediately move out when released. Just eyeballing these parts should reveal the problem.

On another note if this motor wears out can it be replaced with motors from the 480 series or is it something special to this model? It's the classic transport, after all.

However you can note changes in the way cam mode motor is mounted or brackets on Sankyo transport is different. Only Cassette Deck series had Panasonic reel motors ( known to go bad very quickly) and Nak later revrted to Mabuchi- or Sankyo did that? Surprisingly there are large number of spare belts and parts available for all these cassette Decks excepting 20$ motor ? Theoretically you can adapt any DC 6V motor with adequate torque/RPM for this application provided the shaft length is extended. fortunately large number of these two head decks still available to source parts for 3 Head naks kannan --- On Tue, 5/12/09, boitrel wrote: > From: boitrel > Subject: Re: [naktalk] cr2 transport > To: "Talk about Nakamichi Cassette Decks" > Date: Tuesday, May 12, 2009, 4:13 AM > Kannan, > > Good to know that! thank's > > BTW is it the same for exchanging idler-type reel motors ? > for instance, > let's say I want to get a spare reel motor for my BX300, > can I take that > of a BX-150 (or BX-125)?

Yes, one brake was sticking. I guess I didn't check the spring. I changed the lot from the other transport with both hubs. While doing it I noticed a crack in the right plastic pivot which kept the hub from moving freely in the rewind mode. Forward was ok. That's why it played and fast forwarded so well. I glued then filed it smooth. It was a lot of work. Short of changing the whole half I had no other option. It is super fast now in both direction. While I am at it one more last question. The capstan motor of the 582 has a different serial no from the 480 and 482 motors. It also has some electronic stuff (capacitors, resistors) the other motors don't have. It also looks totally different. Does this mean that they are not interchangeable? The reason I am asking is that although this 582 is working really well for now its capstan motor must be 30 years old and it is a little noisy. I have a couple of spares from other classic transports which I thought might help if this one ever goes. Thanks again, Peter Date: Mon, 11 May 2009 08:53:39 -0400 From: ra.ah at verizon.net To: naktalk at naks.com Subject: Re: [naktalk] 582 I've read Kannan's response and he beat me to the punch. It's a long shot, but I suggest you ascertain that in the brake is fully released in the REW mode. Do this by pressing REW with no cassette and turning the takeup hub clockwise by hand, feeling the resistance, which should be small (just press REW again if the deck goes to STOP). This will verify correct brake operation (or not). Good luck, -- Ron Peter Tanner wrote: Yes, I've looked at the parts you've mentioned. They seem ok. However, I've noticed another thing. When I try to spin the right hub (F14, reel hub take up assembly) by hand towards the rewind direction it is extremely stiff. It spins forward without problem. So perhaps the motor and the idler are trying to pull the take up hub in the rewind direction, and it works for about 20% of the tape to be rewound, but then it slows down. Looks like the hub is too hard to pull so the left reel then starts slipping and eventually goes into the stop mode. I've checked the take up reel and it seemed ok, the belt is new from Fred Marrs, and without the belt on the black shut off sensor disc spins freely. Unless that disc starts sticking once the belt is on or something is braking the whole rewind action, I just can't tell. I have another classic transport I keep as a spare as it used to work really well in a 480 which has defective electronics so I'll change the reels from that one over and see what happens. I have noticed, by the way, that in this transport the idler tire has much more clearance from the supply and take up hubs than the transport in the 582. Perhaps because the tire is much more worn, I don't know, but there is only about a mm from one or the other.

But I do not understand "The motor or rather the idler spins the hub but the outer part which is before that clutch like felt pad is slipping". Looking at Fig. 3.8 of the 582 service manual page 32, are you saying that part F13 is slipping on part F15? If so, check these parts for wear (there should be none) and check the felt pad part F16 and spring F17 for correct seating. Parts F13 and F15 should not be able to slip w.r.t each other. Also, when pushing part F13, it should move in easily, but immediately move out when released. Just eyeballing these parts should reveal the problem. Good luck, -- Ron Peter Tanner wrote: Yes, thanks, Ron. I did manage to change the idler tire nonetheless. The old one seemed wobbly and the wheel itself seemed out of alignment. Fast forward and play are stronger than ever but still no fast rewind. I cleaned everything and checked the springs. The motor or rather the idler spins the hub but the outer part which is before that clutch like felt pad is slipping and eventually the deck will go into stop mode. This will happen after about 20% of the tape is rewound. Worse on 100 minute tapes.

The 582 has the classic transport, in which idlers last a long, long time. If the deck runs REW OK, the idler is probably OK (replacing it is kinda messy, too). I would start by cleaning the takeup hub and idler contact areas. -- Ron Peter Tanner wrote: Thanks, I'll go for it then. The only fault I have found is the fast rewind. Very slow. Forward ok. I suppose I'll have to change the idler tire which I dread but so be it. It has a beautiful sound otherwise. On another note if this motor wears out can it be replaced with motors from the 480 series or is it something special to this model? It's the classic transport, after all. I have a couple of spares from a 480 and 481 respectively. Peter Date: Sun, 3 May 2009 09:56:35 -0400 From: ra.ah at verizon.net To: naktalk at naks.com Subject: Re: [naktalk] 582 Your deck is working correctly. All decks deemed by Nak as 'high end' had the capstan run continuously. This guaranteed that the capstan motor was stable from the get go. On the con side, this tends to wear the capstan motor sooner. It's a good idea not to turn the deck on, then let it sit idle, doing nothing. -- Ron Peter Tanner wrote: Hello A friend of mine has a 582 in excellent shape I am thinking of buying if the price is right. While testing it I've noticed that when the power comes on the capstan motor starts rotating immediately. In other words the motor always runs with the capstans rotating even before I press the play button. It plays normal once the play button is pressed. I am more familiar with the 480 series where the motor rotates when the play is activated. Is this normal for this deck? All functions and lights are as normal otherwise.

Funny thing, the only capstan motor I ever replaced on a classic transport was in a 582 -- my own. That was in 1981 or maybe 1982. Got it at the time directly from Nakamichi in Torrance, CA. The speed regulator IC had gone south. They didn't have a replacement IC, so I got a whole motor for $10.20 -- that wasn't that much, even then.

Well, success at last! I decided to begin the meter repair by replacing C901 and C902 because, surprisingly, I had the capacitors in stock, but I did not have any of the ICs. Customarily, I keep only a few low-voltage capacitors in store, and no ICs other than my own 8827 audio opamp. To my surprise, the few low-voltage capacitors I had were the correct values. Replacing the capacitors restored the function of the meter display. If the capacitors didn't solve the problem I had planned to order the ICs from Digikey, but it appears I don't need the ICs. A good spray of Caig did indeed restore the potentiometers. Now the deck runs wonderfully. This has been a year-long project, and I had to take parts from three non-working 680ZX to have one working 680ZX. I never did determine why the original 680ZX deck I began working on wouldn't calibrate or record, but fortunately I was able to take the needed electronics from two other "organ donor" decks and get my 680ZX recording and calibration circuitry working. Thanks for everyone's help! I'm enjoying the deck at long last! On May 5, 2009, at 8:00 AM, Doug Guth wrote: > Double Dittos on the C901 and C902 failures Kermit.

The Sankyo transports have a history of failing cam motors, which the 582 has not. The cam motor is controlled in a feedback loop using the potentiometer on the cam axle. This potentiometer can be dirty, for example after a long dirty storage. But more suspicious are two or three small adjustment pots in the control electronics. These adjust the precise motion and positioning of the cam in each tape function. If the cam adjustments are out of spec, the complete cam mechanism can stall, as seems to be the case with you. An other symptom is immediate stopping after starting play. The SM describes the pots and the adjustment procedure (there are marks on the cam that can be seen when the facia is removed). It is a bit tricky because the separate adjustments do interact with each other, something that can result in surprises. The adjustement pots are week and can fall apart, so be careful. It might help to check these adjustments. Furthermore, anything in the control electronics can be at fault, which can be detemined by analysis and trouble shooting the old fashioned way.

I expect a 620 to be black for radiation of heat purposes, so I would not look for a 620 in silver. 630 could be silver, but I do not think this piece was supplied in silver. I did likewise, not ever see a System 1 Rack in silver, nor the DS200 timer. BUT, I also did not see a Tape System 1 or a System 2 until I made them myself. ;-) So someone could have made a silver Sys1 him/herself. Feel a project coming up....... ; Go for it.... I am currently rebuilding my music room after having moved last Januari. Then I start adjusting my main system which will take all summer. After that I will return to business as usual and hobby some on Nak decks again. And the first project I still have in mind is building an 640, the CD player in the 600 line. Can you imagine a Sys1 with a CD player 640 next to a cassette deck 600 and a tuner/preamp 630? Tantalizing.

IIRC the Dc output is 9.9 or 10Volts to power up the NR 100. Why would you want to use the NR 100 on a dragon/ZX9? ( In fact you can really not connect correctly to the NR.

Actually, it is Q607(2SD1164) that has been replaced by a TIP122, and not Q608. I have also noticed the following (and wrong) behavior relative to the ZERO MEMORY (combined or not) with the REPEAT function: when ZERO is reached in FF or REW, the deck stops and keeps swithing betweem "-0001" and "0000" without either stopping for good (or playing if REPEAT is ON). At this point, if I push the RESET, the deck behaves as it should (stop for good or plays again). So, although it displays "0000", the deck behaves as if zero was not reached... can it be because of the control motor or switches that need to be cleaned? (although i do not think so) Thank's for help.

If so, the function lights will also behave irregular when hitting play (or any other function). The BX series Naks use the Sankyo mechanism and the cam motors do have e history of freezing up. Try moving the motor by hand when hitting play. Then it might free up again and function normal. But the problem will return. For a real solution motor cleaning is needed. Several stories are on the net about this. I reported a repair swapping the motor. But nowadays I simply open up the motor and clean and brush the commuter and leaf contacts.

Many may know I use the 600 and 600-II in my experiments, but few know that one of my 600-II serves as a "guinea pig" to try out improvements to the breed, and for my experiments for improving analog recording overall. Interestingly, most of the "upgrades" sound the same to me, although I admit I truly enjoy the sound of the deck left stock. Nevertheless, after over thirty years of tinkering inside 600s, I have some ideas for changes, although I dislike the term "upgrade." Whether a change to a deck's sound is an "upgrade" is in the ear of the beholder; in other words, it's opinion -- not fact. I'm thinking of things like improving the 600's signal-to- noise ratio without the need for more-aggressive NR systems, (I think I can add 10 dB improvement to the S/N-R of a Dolby B deck, for example), increased headroom, and reduced THD and IMD. But I do not want to lose the essential sound of the 600 series, "hot rod" the sound, or convert them into a CD-like sound. I love the sound of the 600 as-is, and personally the only thing I've desired from a 600 or 600-II is better S/N-R and reduced treble THD/IMD. Those desires notwithstanding, the machines are wonderful to my ears and my desires should be regarded as pedantic changes, not necessary changes. One advantage of the 600's design is that its NR is on a card, for which aftermarket replacements could be designed that include different systems. I do know that gold faceplates are expected for limited edition decks, but may I suggest titanium instead? Why? As you may know I'm an avid photographer and my cameras-of-choice are the Pentax LX, Minox B and Graflex RB.

But the gold LX looks like something worn by an inner-city pimp; it's embarrasingly gaudy and ugly.

In-Reply-To: Message-ID: <717990.37338.qm@web30201.mail.mud.yahoo.com> Hi Kermit, While people might object or comment on any changes made to a product outside the original designer's intent, one has to remember that the designers themselves were sitting in the same situation when the product was being created. I am sure they would have been struggling to define the performance limits of their creations keeping in mind the various non-technical factors that defined what we see as the 600 series today. I am sure however, the we can keep the 600's sound but do with better performance specs and make it a special. Of course fancy things like remote control are a no-no because that detracts from the 600's hand-on appeal. I remember seeing a picture and it indeed does look a good design executed badly. It reminds me of the Limited version of the Technics SL1200 turntable which looks perfectly at home in a underground German disco, but awful anywhere else. However, take a look at the classic Rolleiflex 35S (which was made in Singapore!) which had a beautiful Gold Limited edition. Yes, gold can look beautiful if (and that is a big IF) done right.

Back in the early 1981 I lugged my Nakamichi 550 around in the Balkans working on some field recordings. While I still have the 550, and liked the recordings I made on it, it is not in working order. But that is not really the issue here. I'm in the process of getting ready to digitize these recording I have both a Nakamichi BX-125 and a CR-1a. The BX-125 sounds like it is slipping in the rewind and I'm hoping it only needs a set of belts. Can anyone recommend a good belt supplier, and roughly how much should they cost? How difficult are they to replace? I suspect I ought to do the same for the CR-1a, although it seems to be playing and rewinding fairly well at this point. Both of these machines are used and I suspect neither of them have had their belts replaced since they were purchased. Are there any other things you'd recommend getting serviced. And if so, can you recommend a good person in the Metro DC area? Finally, my main interest is in digitizing the tapes I made way back (not in recording new things), which of these two machines would be likely to produce a higher quality output?

It seems like the majors have stopped producing 60 minute lengths, although some new old stock is still available. This is unfortunate, especially in view of reports of degradation of some older tape formulations. Richard Hess has an interesting report available here: http://www.richardhess.com/tape/history/HESS_Tape_Degradation_ARSC_Journal_39-2.pdf My oldest cassettes are about 27 years old and still play well. It seems that new binder materials came into use in the 1980's and seem less prone to some of the degradation modes. There is still Type II tape available from suppliers to the audio publishing industry, for example, Church groups that publish sound recordings. I've had some good luck, at least according to what my ears tell me, from tape purchased from nationalaudiocompany dot com. The prices are reasonable, 100 tape minimum order, packaging sold separately. It seems to calibrate differently than some of the major brands (more level, less bias) but once calibrated, sounds good. I have no connection with that company, but I thought some list members might be interested. Your mileage may vary.

Extensive web searching is not yielding any decent results. Tech says he can have it rebuilt, but the cost of doing that well exceeds the value of a working deck. I know its a real longshot here, but do anyone of you have any idea where I can get Tandberg parts? Even better, maybe someone here has a Tandberg 9X00 parts unit and and can sell me a motor?

Message-ID: <207626.62495.qm@web30203.mail.mud.yahoo.com> Hi John, The Tandberg capstan motor has some parts made out of ceramic which cracks and thus renders the motor inoperable. Getting a replacement of the same type carries the same risks and may last you just a few more years after all that trouble. However, help is here in the form of a drop in replacement motor and driver board that fits nicely. The kit is available from Sound Smith - you can check their website for more details. I have a Tandberg 10XD and have held on to it for 20 years exactly despite it requiring extensive board repairs and new heads. It seems impossible to get heads for Tandbergs. While very well engineered and having a deserved reputations, their machines sometimes have a strange design and complexity that only seem to add cost. The 9000, 10 and 20 series machines don't seem to age very well, so care must be taken on these machines.

Message-ID: <315349.44282.qm@web65606.mail.ac4.yahoo.com> John, At the risk of making Wouter angry at me again....I have a 9241XD, a TD20A and a 10XD. The 10XD is presently with a tech in restoration. Bala's point about finding a working motor that is susceptible to the same failure, is a good one. I have a non-working 9200 chasing spiders down in the basement. Most probably the capstan motor is working fine. My 'restored' 9241XD was done poorly, it's been back once and it still is not 100%. Same with the TD20A....what started out as a beautifully restored, functional machine has no developed a logic problem. Two different techs and two different approaches to restoration procedures-one willing to do warranty work, the other not so willing and therefore not productive. The motor that runs the capstan on the 9200 does not do it directly, but uses a rubber idler wheel to drive a big flywheel. The reel table motors are individual. the TD20A (and I believe the 10XD) have direct drive motors to their capstans and thus the replacement motor and board available by Soundsmith. The Soundsmith solution is expensive and I've been told, introduces some noise. Also, I think we are talking about AC versus DC motors here, each with their own strengths and weaknesses. Contact me offline,maybe we can work something out. I'm so disgusted with the working 9241XD, that I may part it out on ebay-shoeihell at yahoo.com Kevin  Message: 1 Date: Thu, 21 May 2009 14:20:27 -0400 From: "John Tucker" Subject: [naktalk] Anyone here also into Tandberg and know where to     score    parts?

The motors were built by Papst, and as with everything else in the deck, were of the best quality. The capstan is direct driven as is the reel table motors and they are beautiful when they work. Ultimately, I suspect that a capstan motor could be another candidate if not for it's size.

Message-ID: <787740.15850.qm@web23001.mail.ird.yahoo.com> Hi Kannan There are several battery powered large diaphram condenser mics available, or you might like to consider the dynamic Shure SM58.  The SM58 is realy tailored towards the live environment, although I have had pretty good results with it in the studio.  Large diaphram condenser mics are more suited to what you require.  I do not know much about the battery powered ones, but I should imagine they are much of a likeness.  I have used cheap (bottom of the range) large condenser mics with excellent results.  These require a power source called phantom power.  I have a mic pre-amp, again bottom of the range that supplies this phantom power.  You would also need to consider that the plug on the microphone matches your input.  Most microphones use balanced xlr connections. My set up is large diaphram condenser mic xlr balanced input to microphone preamp, unbalanced 1/4" jack out. I hope this helps.

Therefore, avoid the typical vocal mics such as the Shure SM48*, SM58, PG58, Beta 58, SM57* or 545-SD; Audix F50-BP, Samson R11 or Q7; AudioTechnica ST90, Sennheiser e85 or their other "Emotion" series vocal mics, Audix's OM series, the Shure 55 (new version) or the plethora of Shure SM-58 copies. The MX-100 lacks phantom power, so avoid condensers, especially battery-powered units; these tend to be too noisy for subtle a capella recordings. Sadly, Nakamichi condenser mics are too noisy and tend to emphasize breathiness in vocals of ,any kind -- I have the CM-100* and CM-1000*. I feel you cannot beat ribbon mics -- good ribbon mics -- for female vocals, such as anything made by AEA (Wes Dooley), Beyerdynamic or Royer, but the Beyerdynamic ribbons are my personal favorites for female vocals. Beware the cheap Asian-made ribbons, like Apex, Avant, NAD, CAD, Samson, &c. Unless you want to modify these with a replacement transformer, they just aren't any good for female vocals. Despite their high cost, I dislike SE Electronics ribbon mics, although I've modded a few with improved transformers -- then they become wonderful, but for the price you can buy AEA or Royer which already ARE wonderful. The only condenser mics I like for female vocals are AKG C-12, C-12A, C-414 (never the C-535!), Neumann U-47, U-87; Telefunken ELA-M251(or my Stentorians, of course). All of these are expensive. Very. If you get a C-12, ask me about a mod to its amp head. My suggestions for you would include: NEW MICS: AEA R44 series, R84 series.

A ribbon mic does not need a power supply. Also, the R-44 is relatively inexpensive, Google Marshall R-44 and you'll find them for around $100.00. But, just case it's not exactly right, make sure you can return it for a credit or refund. The Shure SM-58's and similar are intended for close, live work and emphasize upper mids.

Message-ID: <578820.59718.qm@web33308.mail.mud.yahoo.com> Hi Kermit / Paul /Ed and Tom thanks for guiding me on this. I am really overwhelmed by Kermits answer because i had to read it many times and research the available mics and prices. Finally I came down to narrow my selection to Dynamic Mics ( since Ribbons are expensive if really look for good ones - and I got an answer from one seller of vintage mic made me look for dynamic mics more than Ribbons as the first choice ofcourse I am tempted to try Ribbons later) EV RE20 Senheiser MD441U / second choice MD421 EV  635A Also I am trying to find whether one person will sell Shure 300 at low price - AKG D7 AKG D7 is the last in my list - probably the last choice My next question is - I am planning to buy just one mic and MX100 has  three inputs , how do convert this to mono or ingnore the right output but feed left ( connceting the single mic to Left input) to right and left input on the Nak recorder line input? I also like to know whether all these mics will have enough output to feed the MX100 correctly Kermit I will be delighted to hear from you on these choices I have also given below the reply I got from the seller kanann ----------- The m260 is a "bright mic" that also has a pronounced proximity effect. Some have a low cut filter to counter the proximity effect. You'll need to experiment with mic placement to get the most out of it, and you'll need a preamp with at least 65 dB clean gain. If you don't match a ribbon with the right preamp, the results are less than you'd get with a good dynamic. The RE20 is designed to eliminate the proximity effect, and is hard to go wrong with. It's transient response is not going to be as good as a ribbon, but it has a warm full sound that compliments voices very well. The price of either microphone new is within $10 of each other ~$450. I think the RE20 is far more useful - very versatile, rugged, with easy results for voice, and I prefer the sound of it to the m260. However, microphone preference comes down to taste. Whatever you do -- for your application, don't buy a condenser microphone unless you're willing to spend ~1000 (or spend a lot of time researching mics and hunting for good deals) and have a well treated room. ------------------------- --- On Mon, 5/25/09, Kermit Gray wrote: > From: Kermit Gray > Subject: Re: [naktalk] What is the suitable Mic for vocals - using MX 100 ? > To: "Talk about Nakamichi Cassette Decks" > Date: Monday, May 25, 2009, 5:09 PM > Hi Kannan, > > You need a good, clean mic without the usual vocal mic > hotrodding, otherwise you'll add sibilance to your wife's > sound (hissy s sounds), and you'll make her sound breathy > and cheap.

Of the choices you've narrowed it down to, I'd suggest the EFV RE20 because it will do better placed back from the singer, and its tone will remain the same with changes in distance because of the Variable- D design. Another reason I like the RE20 is you can record quite close up yet give an excellent recording that doesn't have that "too close" mike sound, although the recording will be rather dry, because it effectively rejects room noise. If you don't have a good sounding room, this is good news. The EV 635A is an overlooked bargain because it's one of the few mikes that can be used close-up and also not have that "too close" mike sound, yet it is an omni and therefore will capture some room sound sound. These two mikes are as close to foolproof as you can find, in my opinion. The last time I recorded female Indian vocals the recording was on location, so I used my EV RE20 (which was stolen a few weeks later), placed two feet back for one of the singers, who had a strong voice; and 1 foot back for the second singer, who had a quieter voice. I plugged the mike into my Nak 550's BLEND mike input, and had excellent results. The Sennheiser MD421U tends to lose low-level detail more than two feet back, whereas the MD441 is fine as far away as 6 feet. The Beyerdynamic M260 has been made since the 1960s. The comments the seller made about the M260 are spot-on for the older (pre-1990) models, but in recent years Beyerdynamic has retuned the M260 slightly. New production models of the M260 have a built-in bass cut, and aren't as bright as the pre-1990 models. I'd forgotten about the MXL R-44 that Marc mentioned, it is surprisingly good. That said, the sound of ribbon mikes is dramatically affected with changes in preamplifier loading. This is good news/bad news -- it lets you shape the tone by changing loading, but learning to do this can be problematic, time consuming and frustrating for a beginner. That's why the growing trend is to build a preamp into a ribbon mike to ensure the mike has the ideal loading. I expect the MX-100 to have no problem with any of the mikes I recommended to you, with the caveat that if you take the traditional approach to recording Indian vocal music (mike 4 to 6 feet back, mounted overhead, aimed down at the singer), then you'll have too much noise with ANY mike you pick. But closer in, you're okay. Like many have said, tinker with placement to find the best balance. Whichever mike you pick, connect it to the BLEND input of the MX-100, and turn the LEFT and RIGHT inputs fully down. This gives you a mono- to-stereo output with no hassle. If for some reason the mike you choose doesn't have enough output for the MX-100 let me know and I'll make you a dead-quiet booster preamp to match the MX-100 for free.

I stay in South Africa and am the proud owner of a 682ZX cassette deck. My machine has picked up the following problem: When I switch the machine on, the Auto Calibration red indicator light immediately comes on and stays on and the machine does not respond to any commands (ie nothing works), whether a cassette is loaded or not. Could you please comment to the possible cause of my problem, as well as how to fix it. I am not aware of any Nakamichi service centres in South Africa. Is it possible to download a free service manual from a website? Have a great Nat day!!!

Message-ID: <4C1BF913E51D487983ED4B2C75D870C5@superdator> Hello! Today I picked up my latest addition to my collection, a 682ZX in very good condition. Only some minor scratch on top of the cover. Looking inside its clear that this machine has very low playing hours. No rubber dust and no slipping rubber belt! It also have an interesting history being a display deck in the swedish importer Elfa´s showroom. Now to the sad part, the auto calibration does not work and before starting any troubleshooting I thought that I should describe the problem here and see what you guys think about it. When the deck enter the calibration mode the level and azimuth acctuators just "vibrates" a little and sometimes moves a little bit. After a while the cycle ends and the CAL light flashes to indicate that the process went wrong. I have not made any measurements yet to see what kind of signal or voltage the acctuators recieve. Thanks in advance for any advice! Pelle. -------------- next part -------------- An HTML attachment was scrubbed...

Make sure that both of them work smoothly with 3 volts or less. Nak used way too much lubricant on those threads and the lubricant tends to harden. Check the belts but don't replace them with anything to thick or tight as the wrong belt will also cause binding.

If you Dragon doesplayback anyway, you can start with the record head alignment, first. Disconnect CN-5 on the main PCB , that way the NAAC is not working. If you have a test cassette or a very good recorded music cassette youcheck the playback, without Dolby and on120 sec. for Tape type Nr.1, That way you have the most high frequency on the music. Align the playback azimuth to the best high frequency on this tape. Azimuth alignment Rec. head: While recording the 15kHz Testtone, aighn the Azimuth with a screwdriver. TAPE SHOULD NOT STOPP AT THIS TIME! MAKE SHURE TO USE ONLY THE RIGHT SCREWS! for azimuth Set Bias , and Levelfrom the Dragon calibration first to showing maximum Level, Finding maximum reading with setting therecord head azimuth, same time. After this, bias and Level back to 0 db again.0db on the meter will show you 20 below on the 20 kHz test tone. If the Dragon is recording perfect againyou did win! If not, it can be because of a week bias oscillator or a week recording electronic. Some times the electronic works better if you leave it working for a while. If you Dragon playback heads did get alignment , you must look to the black box of the NAAC. When you press play in back or forward , and Playback in Rew. WITH CASSETTE DOOR OPEN. The white point on this black box shouldbe in the middle position. If not you have two various resistors on the main P.C.P to set the middle again. Playback Azimuth Reverence Rev. VR823, for Fwd. playbackVR 824. I have done this, and the trac alignment, it is a step more,to my new Dragon ,it works perfect again.

I know that the vapors can be harmful when inhaled.  But its abilities to clean, are far better than the American Recorder S-721H.  Many long time techs, absolutely hate the S-721H, and claim that it doesn't clean well enought. Especially anything stubborn from a tape head.  It is safe on rubber rollers, but then again, so are other things. TEAC used to make the best rubber cleaner I ever used. Guys/Techs where I worked, has everything registered through OSHA, with all markings on the battels, and the small vials we use at our bench, for chemicals. I remember them having 99.9% Isopropyl and also Xylene, which is a carcinogen, but cleans great, even rubber rollers.

However, I've used many powerful solvents in my work, albeit outside. I have used the following solvents extensively: MEK, Acetone, Naphtha, Denatured alcohol, Trichloroethane and years ago, CarbonTetrachloride. Generally, stronger solvents will dissolve many plastic parts...MEK and Acetone specifically on most plastic parts. California has deemed MEK, Acetone and  Trichloroethane as carcinogens and since most of the chemical distributors don't ignore the CA market, they have boosted their prices to compensate for selling product in CA...to everyone nationwide.  This seemed to happen about ten yrs ago or so. What were relatively cheap chemicals to buy, have now become expensive. They might not seem expensive to the lay person who will buy a quart/pint can and that can will last for many years. I'm caught somewhere in the middle, because I go through a quart can say, every month or so. Bigger users are of course, being hit the hardest. The price on these chemicals has roughly doubled. And.....the more potent chemicals are harder to find.....like  Trichloroethane. Trichloroethane is my favorite because it is completely non-flammable. This was proven to me by a rep who thew a lit match into a parts cleaner filled with the stuff. However, some tape machine manufacturers strongly advise against the use of strong solvents like MEK on their heads. They say it will affect the actual composition of the heads. I've never tested this, because of the cost of new heads. For the most part, I keep the stronger solvents away from the tape path. Lee Hazen used lighter fluid for everything but rubber parts. Lighter fluid is a form of Naphtha, which can also be found in gallon size for camping stoves. Denatured alcohol is good for heads and safe on them. Some people are advocating Everclear which should be safe on them and afterward, in a pinch, you can drink it.;-) Terry Witt, who rebuilds pinch rollers, told me that he uses nothing more than Windex on rubber pats successfully. So after yrs of rubber cleaning chemicals, I've switched to Windex. Windex just seems to take off the dirt and nothing more; leaving the rubber soft and pliable. However, I'm not sure it's the best stuff to attack a old hardened, dirty pinch roller.....unless you have a lot of time at your disposal. I would really question the use of MEK on pinch rollers.....not disputing what you say...but....I would think that particular solvent would unnecessarily dry out rubber type parts and it would 'melt' any plastic parts found in like cassette decks, if it was spilled or flowed onto them.

It means that the solvent has time to dissolve all the crap at the surface of the rubber roller and that yourself, have time to absorb it on a coton (which is not the case with ethylic alcohol or ethanol). BTW, although not important for the Nak cleaner, do not forget that xylenes (with an "s" at the end is actually a mixture of 3 isomers) Xylenes should be used in a well ventilated area as well. bernard rayr0683 at comcast.net a écrit : > > > Paul, > > You are correct.

Firstly Carcinogens: Acetone, MEK, Trichloroethane, and Xylene are NOT listed on the CA OEHHA register as carcinogens.. least ways not on my September 2009 listing. MEK (and Toluene) were thought to be potential carcinogens about 15-20 years ago, but after population exposure studies, they are now , according to the IARC, listed as "not classifiable". Secondly The CA OEHHA register is for "Known carcinogens AND reproductive toxicants". The second part of the name often gets overlooked, so before some one drags up Toluene, and the related Xylene...I'll do it... Toluene is on the register for it's reproductive toxicity to females, NOT for any carcinogenity. Xylene is not listed. Thirdly It is a common mistake to confuse 111 trichloroethylene, and 111 trichloroethane, the end use was often the same. BUT, the former IS a carcinogen, the latter is an ozone depletant, that is why ther usage was/is curtailed. IPA, water, and S-721H IPA (isopropyl alcohol) is water miscible and will absorb atmospheric moisture if kept unsealed. So, keep the lid on!. In my book the jury is out on water deposition directly from the IPA.. I have yet to experience it in my 35 years of playing with cassette decks..and you would need to be using IPA with a water content greater than 12% for this to occur. Water deposition on heads and capstans.. (unlikely on pinch rollers) is much more likely to be a DEW point issue.. a result of the cooling affect of the solvent on the surface being cleaned , as the heat is drawn out of the substrate during evaporation. This localised cooling under the right conditions can cause atmospheric moisture to condense on the substrate.. if anyone has painted with lacquers, this is identical to 'blushing' or 'blooming' . Generally will much more affect people in humid climes. Some of what I read regarding S-721H and 'moisture', I personally attribute to 'marketing'..... On to S-721H.. I will first qualify what I am about to say..never used it as a product, haven't seen it's MSDS... but according to Scott J, and I have no reason to doubt his word, it is pure hexane.. which I have used plenty of... it is a common ingredient in Neoprene and rubber adhesives, and before I set off mass panic over the effects on pinch rollers, it is used as a dilutant not a solvent :o). Hexane will also have dew point issues.. just a different set of temperature/humidity conditions to IPA for it to occur. A side note on Hexane... I would suggest that S-721H would be based on Iso-hexane.. rather than n-hexane, which was cheaper and the much more commonly used chemical until about 10years ago, when n-hexane was identified as a neuropathic toxin. The relative merits of IPA and S-721H(hexane)??.. again my opinion, and for a cassette user.. nothing in it IMHO. (Note to all: We all avoid breathing solvent vapours.. as that is not good for you in anycase.) Both IPA and (iso) hexane are relatively harmless and will not deliteriously affect the plastics used in the construction of our Naks.. though both will potentially damage paint work used on plastic fascia's (580 series), and possibly lettering on all. The concern!!! about the use of IPA drying out pinch rollers equally applies to hexane.. any drying out can only result from some extractives being dissolved out of the rubber...unlikely to affect vulcanised or cured rubbers as usually used on pinch rollers, but can apply to some synthetic rubbers.. particularly those with a high plasticiser or styrene content.. you know the type.. those crappy belts that turn to gunge in your tape decks mechanism. (never seen this happen with a genuine nak belt). I prefer IPA for pinch roller cleaning as it is slower evaporating and for someone of my vintage.. better working time!..and I can source it easily.. but either does, as they say. Same applies for head and capstan cleaning. Where hexane/S-721H has an advantage, IMHO.. it is a more effective solvent for oils and greases, so very relevant in RTR land where there is much more manual tape handling involved and potential transfer of body fats and oils when threading tape, onto parts in the tape path. Back in cassette deck land, liberal use of hexane/S-721H has a higher risk of washing out lubricant from pinch rollers and capstan bearings than does IPA. Lastly a few personal notes on MEK. It is a great solvent for damaging styrenic plastics...the 580 series fascias again, and likely to remove any lettering in a 'flash' from the others. I wouldn't use it to clean heads, as I see a potential risk of attack to the potting compounds used to seal the tape coils inside the case. Where MEK can be useful for us is in the removal of stubborn oxide deposits on capstans, and for deglazing seriously dirtly and polished pinch rollers if new replacements are not readily obtainable.. eg: as was needed on one of my old 600's... If MEK has been used on a pinch roller..it will swell the outer layer, thus I would allow 24-48hours for the rubber to recover before using. Of course MEK is even better than IPA or hexane at 'cutting' out any lubricant.

The electronic 5Hz. RAMM function in these decks lets yo program 15 tracks per side any which way you want to listen to them....provided you recorded on a similar deck.  This is CD like playback of tracks but takes its time as the tape has to be wound. If you want this feature on other Naks then the 680-682 series decks has a space RAMM that will do the job but no programming and sit back and listen here.

Message-ID: <267569.74993.qm@web65607.mail.ac4.yahoo.com> Martin, They have amended the cans sometime in the last yr or so. I.e.: tetrachloroethylene 127-18-4 is not only identified in CA as a carcinogen, but it's presently not allowed for sale there. I don't have a current can of MEK, but in the past it was identified as a carcinogen in CA and I routinely read that on the old cans. You're probably correct in that Acetone is not identified as a carcinogen....I can't find it being outlawed anywhere on the can or as a dangerous carcinogen. More to the point, I don't give a rat's ass what they do or think in CA. You're obviously anal on the health details of these solvents (which is admirable), but I was addressing the specifics of how the cleaners actually work. I haven't tried everything out there, obviously. I'm going with Terry Witt's recommendation on Windex for the pinch roller, shoot me. And as you eluded to, there are some major differences between real rubber compounds and synthetic rubber compounds like Neoprene. I have no idea however, how to identify one from the other. I don't see anything that's been "solved" in the Nak archives (or elsewhere for that matter, including with recording pros) about solvents for tape paths, just many opinions. And FWIW, the same 'unsolved' dilemma over in the R2R forums.

To: naktalk at naks.com Message-ID:     Content-Type: text/plain;charset=iso-8859-1 C'mon Guy's For those that have been down this track so many times before, skip this..for the rest... 1) please check your facts.. the recent comments contain a lot of misinformation. 2) check the naktalk archives.. this topic crops up reasonably regularly. there are a number of urban myths still being perpetuated...... Firstly Carcinogens: Acetone, MEK, Trichloroethane, and Xylene are NOT listed on the CA OEHHA  register as carcinogens.. least ways not on my September 2009 listing. MEK (and Toluene) were thought to be potential carcinogens about 15-20 years ago, but after population exposure studies, they are now , according to the IARC, listed as "not classifiable". Secondly The CA OEHHA register is for "Known carcinogens AND reproductive toxicants". The  second part of the name often gets overlooked, so before some one drags up Toluene, and the related Xylene...I'll do it... Toluene is on the register for it's reproductive toxicity to females, NOT for any carcinogenity. Xylene is not listed. Thirdly It is a common mistake to confuse 111 trichloroethylene, and 111 trichloroethane, the end use was often the same. BUT, the former IS a carcinogen, the latter is an ozone depletant, that is why ther usage was/is curtailed. IPA, water, and S-721H IPA (isopropyl alcohol) is water miscible and will absorb atmospheric moisture if kept unsealed. So, keep the lid on!. In my book the jury is out on water deposition directly from the IPA.. I have yet to experience it in my 35 years of playing with cassette decks..and you would need to be using IPA with a water content greater than 12% for this to occur. Water deposition on heads and capstans.. (unlikely on pinch rollers) is much more likely to be a DEW point issue.. a result of the cooling affect of the solvent on the surface being cleaned , as  the heat is drawn out of the substrate during evaporation. This localised cooling under the right conditions can cause atmospheric moisture to condense on the substrate.. if anyone has painted with lacquers, this is identical to 'blushing' or 'blooming' . Generally will much more  affect people in humid climes. Some of what I read regarding S-721H and 'moisture', I personally attribute to 'marketing'..... On to S-721H.. I will first qualify what I am about to say..never used it as a product, haven't seen it's MSDS... but according to Scott J, and I have no reason to doubt his word, it is pure hexane.. which I have used plenty of... it is a common ingredient in Neoprene and rubber adhesives, and before I set off mass panic over the effects on pinch rollers, it is used as  a dilutant not a solvent  :o). Hexane will also have dew point issues.. just a different set of temperature/humidity conditions to IPA for it to occur. A side note on Hexane... I would suggest that S-721H would be based on Iso-hexane.. rather than n-hexane, which was cheaper and the much more commonly used chemical until about 10years ago, when n-hexane was identified as a neuropathic toxin. The relative merits of IPA and S-721H(hexane)??.. again my opinion, and for a cassette user.. nothing in it IMHO. (Note to all: We all avoid breathing solvent vapours.. as that is not good for you in anycase.) Both IPA and (iso) hexane are relatively harmless and  will not deliteriously affect the plastics used in the construction of our Naks.. though both will potentially damage paint work used on plastic fascia's (580 series), and possibly lettering on all. The concern!!! about the use of IPA drying out pinch rollers equally applies to hexane.. any drying out can only result from some extractives being dissolved out of the rubber...unlikely to affect vulcanised or cured rubbers as usually used on pinch rollers, but can apply to some synthetic rubbers.. particularly those with a high plasticiser or styrene content.. you know the type.. those crappy belts that turn to gunge in your tape decks mechanism. (never seen this happen with a genuine nak belt). I prefer IPA for pinch roller cleaning as it is slower evaporating and for someone of my vintage.. better working time!..and I can source it easily.. but either does, as they say. Same applies for head and capstan cleaning. Where hexane/S-721H has an advantage, IMHO.. it is a more effective solvent for oils and greases, so very relevant in RTR land where there is much more manual tape handling involved and potential transfer of body fats and oils when threading tape, onto parts in the tape path. Back in cassette deck land, liberal use of hexane/S-721H has a higher risk of washing out lubricant from pinch rollers and capstan bearings than does IPA. Lastly a few personal notes on MEK. It is a great solvent for damaging styrenic plastics...the 580 series fascias again, and likely to  remove any lettering in a 'flash'  from the others. I wouldn't use it to clean heads, as I see a potential risk of attack to the potting compounds used to seal the tape coils inside the case. Where MEK can be useful for us is in the removal of stubborn oxide deposits on capstans, and for deglazing seriously dirtly and polished pinch rollers if new replacements are not readily obtainable.. eg: as was needed on  one of my old 600's... If MEK has been used on a pinch roller..it will swell the outer layer, thus  I would allow 24-48hours for the rubber to recover before using. Of course MEK is even better than IPA or hexane at 'cutting' out any lubricant.

The 9 is a so called super tuned version of the ZX7 primarily due to the direct drive capstan configuration and lower wow/flutter. The electronics are supposed to be better "tuned" on the 9. 4. Finally, all the knob marking on the 9 are in gold and the 7 is in red! The writings on the 7 are white and 9 are gold! Soundwise, the bass is better defined( may be the circuitry or the direct drive cogless motor in the ZX9 as directly compared to the ZX7. The ZX7 though, is an incredible machine by itself. Hope it was not too wordy!

I have two ZX-9 and 3 ZX-7 all aligned perfect. I listen with 8 pcs Infinty Kappa 8 . It is very hard to hear any differences between this Decks. The ZX-9 DD- Motor with a Capstan belt has a little better Wow- Flutter. Some time, only if I do the recordings with both decks on the same sort off tape, I hear a little difference in the bass response. Only with very good tape. Me be the little better Wow Flutter does make the very low bass more precise. You don’t hear differences from in some parts different made Main PCB,s If the are any different capatitors in the ZX-9, the are nearly 30 years old in 2009. If the have been working trough all this years, not standing stlll too long, the still work perfect. I like the ZX-7 with his easy to get Capstan Motor ( same Motor in near all ZX- Decks), a little better. I did meter the Wow Flutter from all Decks , the are like the should be. Very low anyway. The are both great Decks, I think it is better to buy two ZX-7 instead off one ZX-9. With two Decks you can check them better and you can compare even the tapes in use, if you make recordings. The condition off the Decks makes the differences in the performance. best ragards Gerhard Am 19.11.2009 um 22:17 schrieb JG: > Hi all, > Anyone can tell me the differences between the ZX-7 and the ZX-9? > Thanks in advance. > Javier. > ----- Original Message ----- > From: hwbosshoss at comcast.net > To: naktalk at naks.com > Sent: Sunday, November 15, 2009 1:27 PM > Subject: [naktalk] Re: Cassette Deck 2 "Err" alert > > Hello! > > I'm betting that the deck's control motor is stuck.

To: naktalk at naks.com Date: Tuesday, November 17, 2009, 7:12 PM Martin, They have amended the cans sometime in the last yr or so. I.e.: tetrachloroethylene 127-18-4 is not only identified in CA as a carcinogen, but it's presently not allowed for sale there. I don't have a current can of MEK, but in the past it was identified as a carcinogen in CA and I routinely read that on the old cans. You're probably correct in that Acetone is not identified as a carcinogen....I can't find it being outlawed anywhere on the can or as a dangerous carcinogen. More to the point, I don't give a rat's ass what they do or think in CA. You're obviously anal on the health details of these solvents (which is admirable), but I was addressing the specifics of how the cleaners actually work. I haven't tried everything out there, obviously. I'm going with Terry Witt's recommendation on Windex for the pinch roller, shoot me. And as you eluded to, there are some major differences between real rubber compounds and synthetic rubber compounds like Neoprene. I have no idea however, how to identify one from the other. I don't see anything that's been "solved" in the Nak archives (or elsewhere for that matter, including with recording pros) about solvents for tape paths, just many opinions. And FWIW, the same 'unsolved' dilemma over in the R2R forums.

To: naktalk at naks.com Message-ID:     Content-Type: text/plain;charset=iso-8859-1 C'mon Guy's For those that have been down this track so many times before, skip this..for the rest... 1) please check your facts.. the recent comments contain a lot of misinformation. 2) check the naktalk archives.. this topic crops up reasonably regularly. there are a number of urban myths still being perpetuated...... Firstly Carcinogens: Acetone, MEK, Trichloroethane, and Xylene are NOT listed on the CA OEHHA  register as carcinogens.. least ways not on my September 2009 listing. MEK (and Toluene) were thought to be potential carcinogens about 15-20 years ago, but after population exposure studies, they are now , according to the IARC, listed as "not classifiable". Secondly The CA OEHHA register is for "Known carcinogens AND reproductive toxicants". The  second part of the name often gets overlooked, so before some one drags up Toluene, and the related Xylene...I'll do it... Toluene is on the register for it's reproductive toxicity to females, NOT for any carcinogenity. Xylene is not listed. Thirdly It is a common mistake to confuse 111 trichloroethylene, and 111 trichloroethane, the end use was often the same. BUT, the former IS a carcinogen, the latter is an ozone depletant, that is why ther usage was/is curtailed. IPA, water, and S-721H IPA (isopropyl alcohol) is water miscible and will absorb atmospheric moisture if kept unsealed. So, keep the lid on!. In my book the jury is out on water deposition directly from the IPA.. I have yet to experience it in my 35 years of playing with cassette decks..and you would need to be using IPA with a water content greater than 12% for this to occur. Water deposition on heads and capstans.. (unlikely on pinch rollers) is much more likely to be a DEW point issue.. a result of the cooling affect of the solvent on the surface being cleaned , as  the heat is drawn out of the substrate during evaporation. This localised cooling under the right conditions can cause atmospheric moisture to condense on the substrate.. if anyone has painted with lacquers, this is identical to 'blushing' or 'blooming' . Generally will much more  affect people in humid climes. Some of what I read regarding S-721H and 'moisture', I personally attribute to 'marketing'..... On to S-721H.. I will first qualify what I am about to say..never used it as a product, haven't seen it's MSDS... but according to Scott J, and I have no reason to doubt his word, it is pure hexane.. which I have used plenty of... it is a common ingredient in Neoprene and rubber adhesives, and before I set off mass panic over the effects on pinch rollers, it is used as  a dilutant not a solvent  :o). Hexane will also have dew point issues.. just a different set of temperature/humidity conditions to IPA for it to occur. A side note on Hexane... I would suggest that S-721H would be based on Iso-hexane.. rather than n-hexane, which was cheaper and the much more commonly used chemical until about 10years ago, when n-hexane was identified as a neuropathic toxin. The relative merits of IPA and S-721H(hexane)??.. again my opinion, and for a cassette user.. nothing in it IMHO. (Note to all: We all avoid breathing solvent vapours.. as that is not good for you in anycase.) Both IPA and (iso) hexane are relatively harmless and  will not deliteriously affect the plastics used in the construction of our Naks.. though both will potentially damage paint work used on plastic fascia's (580 series), and possibly lettering on all. The concern!!! about the use of IPA drying out pinch rollers equally applies to hexane.. any drying out can only result from some extractives being dissolved out of the rubber...unlikely to affect vulcanised or cured rubbers as usually used on pinch rollers, but can apply to some synthetic rubbers.. particularly those with a high plasticiser or styrene content.. you know the type.. those crappy belts that turn to gunge in your tape decks mechanism. (never seen this happen with a genuine nak belt). I prefer IPA for pinch roller cleaning as it is slower evaporating and for someone of my vintage.. better working time!..and I can source it easily.. but either does, as they say. Same applies for head and capstan cleaning. Where hexane/S-721H has an advantage, IMHO.. it is a more effective solvent for oils and greases, so very relevant in RTR land where there is much more manual tape handling involved and potential transfer of body fats and oils when threading tape, onto parts in the tape path. Back in cassette deck land, liberal use of hexane/S-721H has a higher risk of washing out lubricant from pinch rollers and capstan bearings than does IPA. Lastly a few personal notes on MEK. It is a great solvent for damaging styrenic plastics...the 580 series fascias again, and likely to  remove any lettering in a 'flash'  from the others. I wouldn't use it to clean heads, as I see a potential risk of attack to the potting compounds used to seal the tape coils inside the case. Where MEK can be useful for us is in the removal of stubborn oxide deposits on capstans, and for deglazing seriously dirtly and polished pinch rollers if new replacements are not readily obtainable.. eg: as was needed on  one of my old 600's... If MEK has been used on a pinch roller..it will swell the outer layer, thus  I would allow 24-48hours for the rubber to recover before using. Of course MEK is even better than IPA or hexane at 'cutting' out any lubricant.

YMMV... for you it obviously does. That is OK.. What I WAS responding to were the various comments regarding the 'health issues' of certain chemicals, which were as of the time of my post, incorrect. That was MY point. I was addressing these issues, not the people ( who have the best of intentions in raising these points ) but you have obviously taken umbrage at something I said, but in re reading your post and my post can't think what. You mention "They have amended the cans sometime in the last yr or so. I.e.: tetrachloroethylene 127-18-4 is not only identified in CA as a carcinogen, but it's presently not allowed for sale there". Yes, that would correct based on my available info, BUT you introduce yet another chemical into the discussion. This is more commonly know as perchlorethylene and is related to the TRIchlorothyelene (CAS No 79-01-6), and TRIchloroETHANE (CAS No 71-55-6) that I and other posters had referred to, but it is not the same Tetrachloroethylene (CAS No 127-18-4) is classified as a "probable carcinogen". Your next comment, "I don't have a current can of MEK, but in the past it was identified as a carcinogen in CA and I routinely read that on the old cans."... if you re-read my post, I think you'll find I didn't disagree. At that time, and I was 'there' figuratively, that was the CA informed opinion back then. This has since been corrected with the benefit of more investigation and population study. But one thing is certain in the chemical industry, and that is, nothing is, and MEK may go back on the register as a carcinogen at a future date. ( note: in your original post you specifically refer to trichloroethane, not tetrachloroethylene, and mention that MEK and trichloroethane are carcinogens.. that was my only concern) I don't think I am particularly anal, but I am an Industrial Chemist, in Management, in the Chemical Industry, and SHE requirements is part of my brief. I and my fellow chemists have to know what we are dealing with to protect both our staff and our customer's.... because if we don't and there is a problem, our local OSH, people like your OSHA.. would kick our collective backsides from one side of the US to the other and back again. I DO give a rats ass what they do in CA with regards to chemicals, simply because the State of CA seems to be a leader in the pack, they do err on the side of caution, and their information is relatively accessable. They sometimes do jump the gun and are not always right, but their information is often the starting point of any SHE investigation related to chemical hazards I have to do. I don't see Windex on the shelves down here in NZ, but that could just be a branding issue as SC Johnson products are readily available here. If it works for you, great...it 'solves' your problem to your satisfaction.. Such chemicals are typically mostly water based, with some surfactants, alcohols, glycerine, dyes and fragrance oils, but I will admit I don't have the MSDS for Windex in front of me. I would caution the use of scented varieties because of the traces of 'smelly' oil. A 90:10 mix of demin or deionised water and methylated spirits should be as effective without the potential contamination issues.

Either way, I'll ask my techie. Willie and Gerhard: my techie and I scoured the service manual and just could not find the part listed there. So we took the part out from the deck and read the part number of the back. It says 203B or 2038 - it was a bit hard to read. The techie thought it was a 'B' because it would stand for linear, or something like that. So I can't confirm if it's the same part number. I sure hope it is. Does anyone know? I used to have the service manual on PDF but lost it when my PC died some months ago. I only have a printed version, which is not easy to read. I'll be interested in buying the part from either of you if it's the right one. Thanks for your replies.

My techie made a new post and that's now fine. But part of the damage was that the pitch control also got pushed in. It turns out that the center pin at the back of the pitch control - it's a center indentation pin that goes into a small square object with four wires coming out the bottom of it - was pushed into that square object and done some damage. It's unreparable, because the square thingy is riveted; it needs to be replaced, because without this the deck has no stability of sound. So, a cry for help! Does anyone have one of these objects - I'm willing to pay for it - perhaps from a spare parts deck? The part number is 203B, which appears to mean it's a 20K linear. Keen to hear back from anyone who can help. Regards, Bernard White Windows 7: Make your own home movies.

Message-ID: <383294.96125.qm@web65610.mail.ac4.yahoo.com> Martin, "Your mileage may vary" must mean different things in NZ. I wasn't aware that it has become the standard for:"This discussion has closed." ;-) More to the point, I often object to absolutes, especially when even the pros in the recording industry argue over the 'correct' solvents for tape paths. Or...they have their own brew of something or other. I think it's easy for a lay person to mix up  tetrachloroethylene/ triIchlorothyelene/ triIchloroethane. Probably at one time or another, I've used them all. How much different they are with regard to actual cleaning properties (carcinogenic properties aside), I couldn't tell you. Tetrachloroethylene 127-18-4 is what I can get my hands on these days quite easily and I use it in very well ventilated areas. Dropping seals, O--rings and other rubber/neoprene into a vat of this stuff for 10 minutes will restore them to their original shape and pliability. This is extremely useful for me in my trade. However, it's a whole other animal to bring this stuff inside to my recording toys.  Terry Witt rebuilds pinch rollers and other rubber type assemblies for the recording trade. He is very well known and thought of here in the States. His recommendation was simply; Windex. I've tried it with extremely amiable results. To borrow your term; YMMV. As far as CA erring on the side of caution, that's most of the reason their construction industry has become so crippled. All methods and substances used in the construction industry there, have to be documented, filed and verified with a cumbersome paperwork process. And like you said yourself, they (CA's regulatory agencies) keep changing the 'rules'. This make unreasonable burdens on the contractors and drives the end prices of their jobs to ridiculous levels. It has resulted in a HUGE migration of people from southern CA to ransack the Pacific Northwest (and elsewhere) for homes/commercial property where comparably, they can get twice the footage for their dollar that they got in CA. Therefore, to most of us who are affected by this daily, that over-regulation process in CA has not been a prudent and working system....hence my comment about CA. I can't tell you as well if Windex has dyes and fragrance oils, but since it's designed for clear glass, I doubt if it leaves much residue on surfaces. Yes, it works for me. Again, as I stated before, this issue (solvents in the tape path) has not been 'solved' conclusively by any 'archives' anywhere, nor is it likely to be in the near future.

YMMV... for you it obviously does. That is OK.. What I WAS responding to were the various comments regarding the 'health issues'  of certain chemicals, which were as of the time of my post, incorrect. That was MY point. I was addressing these issues, not the people ( who have the best of intentions in raising these points ) but you have obviously taken umbrage at something I said, but in re reading your post and my post can't think what. You mention "They have amended the cans sometime in the last yr or so. I.e.: tetrachloroethylene 127-18-4 is not only identified in CA as a carcinogen, but it's presently not allowed for sale there".  Yes, that would correct based on my available info, BUT  you introduce yet another chemical into the discussion. This is more commonly know as perchlorethylene and is related to the TRIchlorothyelene (CAS No 79-01-6), and TRIchloroETHANE (CAS No 71-55-6) that I and other posters had referred to, but it is not the same Tetrachloroethylene (CAS No 127-18-4) is classified as a "probable carcinogen". Your next comment, "I don't have a current can of MEK, but in the past it was identified as a carcinogen in CA and I routinely read that on the old cans."... if you re-read my post, I think you'll find I didn't disagree. At that time, and I was 'there' figuratively,  that was the CA informed opinion back then. This  has  since been corrected with the benefit of  more investigation and population study. But one thing is certain in the chemical industry, and that is,  nothing is, and MEK may go back on the register as a carcinogen at a future date. ( note: in your original post you specifically refer to trichloroethane, not tetrachloroethylene, and mention that MEK and trichloroethane are carcinogens.. that was my only concern) I don't think I am particularly anal, but I am an Industrial Chemist, in Management,  in the Chemical Industry, and SHE requirements is part of my brief.  I and my fellow chemists have to know what we are dealing with to protect both our staff and our customer's.... because if we don't and there is a problem, our local OSH, people like your OSHA.. would kick our collective backsides from one side of the US to the other and back again. I DO give a rats ass what they do in CA with regards to chemicals, simply because the State of CA seems to be a leader in the pack, they do err on the side of caution, and their information is relatively accessable. They sometimes do jump the gun and are not always right, but their information is often the starting point of any  SHE investigation  related to chemical hazards I have to do. I don't see Windex on the shelves down here in NZ, but that could just be a branding issue as SC Johnson products are readily available here. If it works for you, great...it 'solves' your problem to your satisfaction.. Such chemicals are typically mostly water based, with some surfactants, alcohols, glycerine, dyes and fragrance oils, but I will admit I don't have the MSDS for Windex in front of me. I would  caution the use of  scented varieties because of the traces of 'smelly' oil. A 90:10 mix of demin or deionised water and methylated spirits should be as effective without the potential contamination issues. As before, YMMV Martin -------------- next part -------------- An HTML attachment was scrubbed...

His remote is equally good for Naks. The Cr7 was made during an  evolving digital market mainly to compete with the CD medium which was making quick inroads into mainstream. Therefore, the sound was made to be crisper than any of the older Naks including the Dragon and the ZXL series decks. Yes, the CR7 sounds very close to a clean CD esp with dolby C. There is a little trade of  in bass but the treble sounds phenomenal. IMHO, nothing comes close to the 1000ZXLs sound...May be just my preference but all three of my 1000ZXLs' outperform all other decks I have in playback/ recording functions. The CR 7 may playback certain tapes better due to azimuth issues while being recorded. Its a superb deck if you have lots of bad azimuth recorded tapes. The 1000ZXL has three adjustment parameters besides azimuth on the recording function, viz., bias,record  eq and level for each channel while calibrating. The Cr7 does only two,namely bias and level. That gives the ZXL an advantage of obtaining ruler flat frequency response of 20Hz.-20Khz. +-0.75 at 20dB. .... and yes this is true. It does sounds better when all is said and done. Again my experience and opinion strictly.

Does  the CR-7 sound closer to a clean CD ? Thank you very much !

The original owner sold it claiming the capstans no longer rotate and figured it was the belt. Indeed that was not the problem and I managed to get the deck up to snuff, at least mechanically. The problem is the output. When moving the output slider up from point 0 there's static sound coming out at the point 5 level. I took off the faceplate and squirted a little Deoxit in the output slider control. Now I have the same problem, but when I move the level up to point 5 there's a little music. I played back and forth with the slider around the point 5 mark and got a little music, sometimes hum, and the same old 'a lot of static'. Now with a little music, I can sometimes identify the song on the tape. NOTE: There's no static on the output from point 0 to the point 4 mark, most of it is on the point 5 -7 mark, and little static from point 7 to the max. level. Could this be a slider switch problem or perhaps orange capacitors? Please advise. Thank you. _________________________________________________________________ Windows 7: It works the way you want.

Demand and speculation is contributing to their rising prices, which is good but may be not good for those who have yet to attain their dream Nak. The recent article in Hi-Fi news would have further cemented the status of Nak equipment, as how they have succeeded in doing with turntables, reel to reel and tuners. The way forward I see for cassettes is slightly different though from the above examples. Because of the lack of new blank tapes manufacture, cassettes are definitely going to be niche and esoteric. They are not going to go away though - It would be no surprise if cassettes outlive Blu-Ray DVDs, though this is not going to happen mainstream. Meanwhile, let us not be jealous because Nak has made so many types of decks of so many numbers that there is more then enough to go around! Cheers!

When I started collecting, I never though I could get a top-end Nak, so I got other decks. But I kept looking and found a RX-505 for cheap, tried to fix it myself, failed, and had two techs works on it. Then out of nowhere, a damaged 700ZXL with external Dolby C turned up. Willy fixed that one. I can't brag about 'deals'; how I just put in a belt kit and my machine rivals factory spec etc. I paid the price of admission and then some. However, it was worse with the Tandberg R2R's .Too many machines, too little space....what a unpractical hobby!;-) It's nice to have 'dreams' and all that, but lusting for a 1000ZXL or 1000ZXL Limited is one of the more impracticable dreams out there. There are better bargains at present with R2R machines, which usually outperform cassettes. Plus the fact I belong to a R2R group where on occasion, a member will donate a perfectly good machine to another member who is struggling to collect. Anyway, to really hear the difference between a 700 ZXL and a 1000ZXL, you'd need some really extraordinary equipment, speakers and source material-way beyond what most of us have (or want to have). And ears that haven't been damaged and ravaged by age.;-). However, I think you're correct about high-end cassette machines and a niche market. And doubly so about the blank tapes, unless someone would again market them. It seems to be profitable in R2R as witnessed by ATR and RMGI....so I think someone could pull it off....maybe even the same companies since they're almost there anyway. I don't think the jury is quite out yet on high-end blank cassettes....seems to be a HUGE amount of interest and prices being paid for NOS. When a steady supply of new R2R tape was established, it really kicked the prices of used tape down. There is absolutely no reason now to covet old R2R tape of any manufacture...the new tape is just better in every way. The shell and the mechanical parts in the cassette may be what's holding back future manufacture?-I dunno. Certainly the tape itself is more than just possible.

Demand and speculation is contributing to their rising prices, which is good but may be not good for those who have yet to attain their dream Nak. The recent article in Hi-Fi news would have further cemented the status of Nak equipment, as how they have succeeded in doing with turntables, reel to reel and tuners. The way forward I see for cassettes is slightly different though from the above examples. Because of the lack of new blank tapes manufacture, cassettes are definitely going to be niche and esoteric. They are not going to go away though - It would be no surprise if cassettes outlive Blu-Ray DVDs, though this is not going to happen mainstream. Meanwhile, let us not be jealous because Nak has made so many types of decks of so many numbers that there is more then enough to go around! Cheers!

Sometimes, squirting cleaner from the outside doesn't do the job -- the potentiometer has to be removed, dismantled and the track(s) cleaned directly. If you choose to do that, be extra careful -- it's easy to do damage. Another possible culprit is the PCB tracks around the potentiometer. To check, set the potentiometer just before the noise comes on (say, at '4') and tap the pot body and nearby PCB areas.

Do you mean the Ebay Member from Hamburg who was taking the Photos of his ZXL sitting in front of the ZXL Limited in his underwear ? I think the golden ZXL was always a bit too shiny! I don,t think it is the same man. 8 weeks ago a Swiss Ebay Member was selling only one ZXL-Limited three times. Always saying after the selling, buyer did not pay, put it on sale again. But they did pay after a while Ebay did stopp this sellings. Good luck anyway! Don´t t forget, a Naka transport needs 3 inches air bubble minimum around the deck in a box. Lots off US Ebay Sellers know that. "Europe" does not know it.

It is very good to the Naks if they do some work, specially if the do the work to erase and and record, even with no Level! The heads keep very long and if you use good tape on lets say two or three machines, they will last your hole live. Moving keeps the transport and the capacitors on live!

The erase head is only capable of dealing the two channels it is addressing and its depth of erasure is not as good as a bulk degausser. Using the re-record process will always leave small traces of the original waveforms which were recorded on the tape and will consequently cause small amounts of intermodulation distortion in the fresh recording. Bulk degaussing a tape is always a preferable method but it does not allow you to save any of the original recording so if you wish to reuse one side of the tape you have no choice but to use the erase head.

Hello Jay... thanks for the reply! I think that for my first cassette deck ever I shouldn't go *too* crazy, so I was thinking about us$250 max. I would primarily use it for listening, and occasionally use it for recording so that I could play it back into the computer for a nice tape sound :) All the best, -norm From ronami at yahoo.com Mon Nov 30 04:26:25 2009 From: ronami at yahoo.com (Ron) Date: Sun, 29 Nov 2009 19:26:25 -0800 (PST) Subject: [naktalk] Tape degausser In-Reply-To: <0KTW005Z16B38Y8V@vms173017.mailsrvcs.net> Message-ID: <564596.3927.qm@web50405.mail.re2.yahoo.com> In principle, you are right. However, bulk erasing a tape before recording should result in lower hiss, assuming one uses a good degausser. Also, the erase heads do not erase remnants of recordings previously done on another deck, whose head height was not *exactly* the same. I always bulk erase a cassette before re-recording On it. -- Ron --- On Sun, 11/29/09, Roland wrote: > From: Roland > Subject: Re: [naktalk] Tape degausser > To: mrm12000 at cableone.net, "Talk about Nakamichi Cassette Decks" > Date: Sunday, November 29, 2009, 5:25 PM > Okay, I've a dumb question.  Why > are degaussers > necessary when an erase head does the same > job?  Or am I mistaken that they do the same > job?  Just curious. > > At 03:45 PM 11/29/2009, you wrote: > >The Geneva PF250 is strong enough (3000 gauss) > >to erase metal tapes, and used ones > >occasionally show up on eBay.

Over the years, I've heard a lot about the 600 from owners on this group. I finally bought one just two months ago and all I can say is wow!! It's like the littel engine that could and does!

It's nothing more than an electromagnet, powered from a power outlet (115VAC in the US, 230VAC in most of Europe). The field from a good bulk eraser will completely penetrate the tape cake, providing better erasure than a deck erase head. My eraser is actually designed to erase 1/2" video cassettes, so doing audio cassettes is easy for it. Erasing is done just like demagnetizing heads. The eraser is turned on away from the cassette, then brought SLOWLY closer, waved SLOWLY over the tape, then withdrawn SLOWLY away and turned off when 3 ft. or so away. Metal cassettes require the eraser to stay close to the tape a while longer, due to their high coercivity. I bought my eraser at Radio-Shack (a chain of cheap stores). I don't recall how much it cost. Probably, in the $10 to $15 range. That was many years ago, so I suspect they cost more today. Certainly, a quality bulk eraser (which mine isn't) will cost more; still mine has done a credible job since I got it, on both audio and video cassettes. -- Ron --- On Mon, 11/30/09, Wouter Heijke wrote: > From: Wouter Heijke > Subject: Re: [naktalk] Tape degausser > To: "Talk about Nakamichi Cassette Decks" > Date: Monday, November 30, 2009, 5:19 AM > This is interesting, I never did > this! > How do you bulk erase Ron?

Just follow the service manual, page 44. But start at step 2 and if you cannot get equal outputs on TP101 and TP201, do not proceed to step 3 until the problem is fixed. If both step 2 and 3 are correct but you still see the problem with the tone generator off, measure at CN1-1. (you'll need to set your VM to a sensitive range). Presumably, it won't be 0V (as it should). Compare to the reading at CN1-4, which will be 0V or very close. If so, measure back at Q209-e (compare to Q109-e), then Q208-c (compare to Q108-c), then IC-302-1 (compare to IC302-7). Somewhere along the way, you should be able to find the reason for that high reading.

For the comparison to make sense, use prevalent prices (which £2 for a Shure V15-II isn't) and compare apples to apples (new to new, used to used, ebay to ebay and high end dealer to high end dealer). In my case, I have a Dual 5000 (using ebay prices: $250 to $400) with Shure V15VMR (~$300) and Hagerman Bugle phono stage ($180 new) for a total of about $800. I intend to replace the cartridge with a Shure V15VxMR -- add another $50 t0 $100. I am also buying an RCM, the cheapest of which I could find is $150. Cleaning fluid will be a running expense. Figure grand total for record playing at about $1000. I compare this to a Pioneer DV-59AVi DVD player that can be had for about $250. Based on the above, I stand on my original statement: most CDs sound better than most LPs on similar cost equipment (not to mention, the DVD player has the huge advantage of providing excellent video). This comparison becomes downright dramatic when I compare to my 10 year old Denon carousel CD player ($25 to $50 on ebay), that is not quite as good as the DVD player, but still stands up to most LPs. . -- Ron John Chapman wrote: > Hi Ron, Doug and others. > > Doug's experience is mine exactly - I'm a drummer and would be > guitarist and I have both vinyl and Cd versions of Dire Straits (which > to my ears - or pressing are NOT in the pantheon of great recordings). > Try any Paul Simon album or Cat Stevens. > > I had a Thorens TD 160, standard arm and Shure V15 II which I > collected from a tip for £2.

There are so many variables from source material, i.e. studio practices, to listening environment, to humidity in the air that the debate should go on forever! ;o) My wife and I do have fun listening with friends to both CD and LP and occasionally a 2nd Gen copy of reel master tapes. Earlier this summer we had a professional drummer/singer and her husband over listening to music on our Hi End system. Threshold Audio Pre and Power amps driving Wilson Audio WATT/Puppy system with Mark Levinson CD Transport and DAC. She loved the sound of her favorite CDs. Then my wife smiled and told me to spin some vinyl on the Micro Seiki 1500 with a SAEC Tonearm and Talisman Cartridge. (Roughly $8000 for the Digital front end and $40 >>> >>> 00 for the Vin! >>> yl system) I put on a standard issue Dire Straits Brothers in Arms album. Our friends jaw hit the floor and she said, "Wow! Now that's how I hear the drum kit!" They came over again recently to listen and she had an album from the jazz music school where she attended in the '70s. I cleaned it up on the Nitty Gritty and put it on. (It was a direct to disc recording!) All of our jaws hit the floor!!! Much fun indeed!! I'm not anti CD, I just realize that there is a lot of wonderful music to be had by dragging a rock through those black vinyl grooves! >>> >>> >>> Doug Guth >>> Field Service Engineer >>> Multi Media Services >>> 1029 Thousand Oaks Blvd. >>> Greenville, SC, 29607 >>> (864) 297-8533 >>> >>> >>> -----Original Message----- >>> From: Ron [mailto:ra.ah at verizon.net] >>> Sent: Sunday, September 20, 2009 11:35 AM >>> To: Talk about Nakamichi Cassette Decks >>> Subject: Re: [naktalk] CD vs Vinyl - A player for the rest of us? >>> >>> >>> Actually, on purely technical grounds, CDs are based on a far better technology that LPs.

I know I could not get over £100 for my TD150. I bought the Marantz for £150 but its not as good as the vinyl. I paid £700 for the Lector (ex display) and neither is that so I could affrd to spend some more on the vinyl side if I sold the Lector! They play though my Croft pre-amp which has a phono stage in it. If you asked which device it would have to be if I only had to choose just one to live with it would be the TD160 which is better than any of my CD players. And I'd rather have the ZX7 than the CD players too - recordings from vinyl are better than CD equivalents save on S/N issues. Running costs: If I cleaned my records (500) every year, it might cost me 5 litres of Isopropanol for £20 and distilled water. I certainly won't be doing that. At every 1000 hours I will need to retip my cartridge - (£80 Stylus Expert). That would be once every 3 - 4 years, plus a drive belt £10. Very low running costs, especially in view of the higher energy levels required to run the CD player, and the Marantz is showing signs of the laser failing. Conclusion: there isn't one: we obviously all like different things from our audio equipment, which is why we all have different setups. I hope we all continue to cheerfully disagree otherwise we would none of us subscribe to this excellent lifeline for our cherished Naks and everyone would have the same kit and life would be extremely tedious.

URL: From ra.ah at verizon.net Sat Oct 3 17:00:41 2009 From: ra.ah at verizon.net (Ron) Date: Sat, 03 Oct 2009 11:00:41 -0400 Subject: [naktalk] CD vs Vinyl - A player for the rest of us? Message-ID: <4AC76719.3040909@verizon.net> Until now, I have never had a chance to made a 'before and after' comparison of RCM (Record Cleaning Machine) cleaned records. I have listened to RCM cleaned records (sounded OK, I guess), without knowing what effect, exactly, the cleaning made. I have cleaned records by hand, using the Rat Shack solution and grease elbow many times, with mixed results. The cleaning invariably did improve noise, but never completely removed it. . Recently, a list member (thanks, again, Dan) has generously offered to RCM clean a couple of records for me. I sent him two used records that I bought for a buck a piece. Both had been seriously attacked by mold and had very high surface noise (smelled it, too). After several hand cleanings, the DG record background noise was almost -- but not quite -- gone, but sound remained muffled and distorted. The Columbia record noise level was also improved, but not to an acceptable level. Both records were taken out of the 'sell, give or throw away' pile, as I expected to never listen to them again. Dan cleaned both records. The DG record was cleaned with the G.E.M. Dandy water pressure machine (with no vacuum solution removal). The Columbia record was also cleaned with a VPI machine, after the water pressure RCM failed to remove all noise. Results: the DG record background noise was almost (say, 99%) eliminated. The muffled, distorted sound became good to very good, except for full orchestral passages, where I can now hear some groove damage of the kind that occurs when a record is repeatedly played with a very low compliance cartridge or with a worn stylus. Before, this was completely swamped by the constant poor sonics. The Columbia record, after all the repeated cleanings, still has some surface noise left. I'd say 90% was removed. Sound is easily much better. In fact, it's surprisingly good. Results of the test: first, I have added both records to my collection, as quite acceptable for future listening. Second, I put in an order for the G.E.M Dandy RCM. It's $149. I'd like to publicly thank Dan for making this experiment happen. -- Ron -------------- next part -------------- An embedded and charset-unspecified text was scrubbed...

There are so many variables from source material, i.e. studio practices, to listening environment, to humidity in the air that the debate should go on forever! ;o) My wife and I do have fun listening with friends to both CD and LP and occasionally a 2nd Gen copy of reel master tapes. Earlier this summer we had a professional drummer/singer and her husband over listening to music on our Hi End system. Threshold Audio Pre and Power amps driving Wilson Audio WATT/Puppy system with Mark Levinson CD Transport and DAC. She loved the sound of her favorite CDs. Then my wife smiled and told me to spin some vinyl on the Micro Seiki 1500 with a SAEC Tonearm and Talisman Cartridge. (Roughly $8000 for the Digital front end and >>>>> $40 >>>>> >>>>> 00 for the Vin! >>>>> yl system) I put on a standard issue Dire Straits Brothers in Arms album. Our friends jaw hit the floor and she said, "Wow! Now that's how I hear the drum kit!" They came over again recently to listen and she had an album from the jazz music school where she attended in the '70s. I cleaned it up on the Nitty Gritty and put it on. (It was a direct to disc recording!) All of our jaws hit the floor!!! Much fun indeed!! I'm not anti CD, I just realize that there is a lot of wonderful music to be had by dragging a rock through those black vinyl grooves! >>>>> >>>>> >>>>> Doug Guth >>>>> Field Service Engineer >>>>> Multi Media Services >>>>> 1029 Thousand Oaks Blvd. >>>>> Greenville, SC, 29607 >>>>> (864) 297-8533 >>>>> >>>>> >>>>> -----Original Message----- >>>>> From: Ron [mailto:ra.ah at verizon.net] >>>>> Sent: Sunday, September 20, 2009 11:35 AM >>>>> To: Talk about Nakamichi Cassette Decks >>>>> Subject: Re: [naktalk] CD vs Vinyl - A player for the rest of us? >>>>> >>>>> >>>>> Actually, on purely technical grounds, CDs are based on a far better technology that LPs.

Nakamichi would have been very unlikely to use a standard font because they would have to pay serious bucks for the copyright. You can send someone a letter with whatever Microsoft bought rights to but if you use it commercially watch out. Prosecutions are rare of course because people ignore copyright law. I have many thousands of fonts in my library (Linotype Hell lists 3,000 alone) but in the days when I would use them for an exhibition or museum I would have to pay the owner for the use of it. In the end it is easier for serious commercial use to make up your own font in Fontographer or what ever the current font maker is now, then name and copyright it and I suspect that is what Nakamichi did. It could take weeks to find one with the exact same characteristics etc. In those days, of course, it wasn't done on computers - there were such things as sign writers and graphic artists who worked on drawing boards! In this case, because the R is merged into the G and is a different font to the other text, I suspect it they have taken a trendy 70's font and then altered it. If you scan it, you could possibly take it into illustrator and replicate it there. They used the A in NAAC too. Its certainly not standard to anything Microsoft put out. best of luck John Chapman On 4 Oct 2009, at 14:31, Ron wrote: > > Isn't the font rather easy to locate?

I've heard nothing but raves about the G.E.M Dandy RCM, even though some have complained about the plumbing hook up and mess in the sink (smaller sinks especially). I can easily handle the plumbing problem, but what I've heard is that the G.E.M. Dandy even out cleans the expensive vacuum type RCM's.  So then....in your post are you saying that Dan's VPI bested the G.E.M Dandy, but you're buying the G.E.M. Dandy anyway, because of the price?

To: Talk about Nakamichi Cassette Decks Message-ID: <4AC76719.3040909 at verizon.net> Content-Type: text/plain; charset="iso-8859-1" Until now, I have never had a chance to made a 'before and after' comparison of RCM (Record Cleaning Machine) cleaned records. I have listened to RCM cleaned records (sounded OK, I guess), without knowing what effect, exactly, the cleaning made. I have cleaned records by hand, using the Rat Shack solution and grease elbow many times, with mixed results. The cleaning invariably did improve noise, but never completely removed it. . Recently, a list member (thanks, again, Dan) has generously offered to RCM clean a couple of records for me. I sent him two used records that I bought for a buck a piece. Both had been seriously attacked by mold and had very high surface noise (smelled it, too). After several hand cleanings, the DG record background noise was almost -- but not quite -- gone, but sound remained muffled and distorted. The Columbia record noise level was also improved, but not to an acceptable level. Both records were taken out of the 'sell, give or throw away' pile, as I expected to never listen to them again. Dan cleaned both records. The DG record was cleaned with the G.E.M. Dandy water pressure machine (with no vacuum solution removal). The Columbia record was also cleaned with a VPI machine, after the water pressure RCM failed to remove all noise. Results: the DG record background noise was almost (say, 99%) eliminated. The muffled, distorted sound became good to very good, except for full orchestral passages, where I can now hear some groove damage of the kind that occurs when a record is repeatedly played with a very low compliance cartridge or with a worn stylus. Before, this was completely swamped by the constant poor sonics. The Columbia record, after all the repeated cleanings, still has some surface noise left. I'd say 90% was removed. Sound is easily much better. In fact, it's surprisingly good. Results of the test: first, I have added both records to my collection, as quite acceptable for future listening. Second, I put in an order for the G.E.M Dandy RCM. It's $149. I'd like to publicly thank Dan for making this experiment happen. -- Ron -------------- next part -------------- An HTML attachment was scrubbed...

I don't think I have ever worn a stylus, but I have replaced several, damaged through accidents. So, since V-15VMR styli are so difficult to find nowadays, I am extra careful. Have been using the same stylus for the past several years with no mishap. So far, it looks under the microscope like new. Just in case, I have made extensive 'inet searches.

Between cleans, you have to give time for the record playing surface to 'heal'. Because the groove walls are very delicate, excessive cleaning will damage your records just as much as very light tracking styli would. I would suggest gradual cleaning and regular playing to slowly bring the dirt out. The VPI itself is awesome. I use traditional hand washing techniques with the VPI, and the result is a stunningly quiet backdrop.

The two main problems are belts and lubrication.

My 582 has a similar issue, but not exactly the same... so I will piggy-back on this 582 post. My 582 has a stronger right channel when I record, and the left VU meter seems more sensitive. After I've set the bias/level for the particular tape being used, I must adjusting the recording balance just to the right of the 11 o'clock position or I end up with a very imbalanced recording. The VU's look relatively close at that point and playback on other units (as well as the 582) results in pretty close to perfect balance at that point. I'd say its more of a nuisance than a real "problem" but the deck is so nice that I'd really like to have it at 100%. Any ideas who can fix this and roughly what it would cost? I'm 97% sure that a tweak of this nature is beyond my abilities.. Thanks in advance for any help.

It works very well but I've noticed that the right meter indicates 10db more than the left one. In other words when I turn the deck on the left meter is at the minimum, -40 db while the right shows -30 db. This could mean that my record and bias calibrations are out as I set both indicators at 0 db. When I record a 400hz signal at 0 db on both channels and I play it back on another deck the right channel is stronger. Can this be adjusted and if yes how?

What is it 'healing' from? How long does 'healing' take? Also, I understand how the stylus jumps around in the groove -- thus damaging it -- when VTF is too low. But how is that related to 'excessive' cleaning? The water pressure is nowhere near stylus pressure and water isn't quite as hard as diamond. The water doesn't remove any vinyl at all. It stands to reason that no vinyl will be removed even if the record is washed for hours and hours.

This method of lifting the dropping the unit was originally suggested for Apple II computers. Back then, the heat of the system caused the motherboard to warp and semiconductors to 'pop' out of their sockets. Apple's remedy of lifting the dropping the unit supposedly helped seat the components back, making the computer function again. While it might jolt the motor out of it's dead spot, I would not want to do it to the cassette deck, even though it may be a hard rock of a 680ZX.

Of course these days, lots of myths are being laid to rest as vinyl playback is going through a period of renaissance. If you consider the size of the groove, and the consequent thickness of the groove wall in between, it really is very thin. On records pressed in the 70s and some in the 80s, the grooves were packed to tight, with a quiet front end set-up, you could here a song starting a fraction of a second as the supposedly quiet band has some modulations of the song that is coming up. That gives you an idea how thin the groove wall really is... While some records picked up at a local flea market may be very dirty, you need to slowly and gently get it cleaned with multiple washes. But my advice is to take it step by step with a manual clean and a RCM followed by some play time. As vinyl is really a soft material, it needs time to recover.

The other arguments against vacuum cleaning is that it does not actually remove all of the dirt from the landings and in effect dries it further.

The balance control is intended to compensate for imbalance in the signal from one channel to the other and setting it around 11 o'clock is not at all rare. John's problem is that the meters show different readings when at rest. As long as playback is correct both on your machine and others, I would say you don't have a problem.

Now, on to healing. I recall many, many decades ago there were these devices that you would attach to the player deck and there were be a spray of water into the groove before the stylus and a vacuum afterwards. The thought was that the friction of the stylus in the groove would heat up the vinyl causing a slight reconfiguration of the groove walls. I believe these devices came out after the introduction of the 120g flaccid LPs as I would like to call them. Any record cleaning system would have been tested to make sure the action of cleaning the groove was considered 'non-destructive'. I'm with you, cleaning with water for hours and hours would do no harm to an vinyl under normal water pressure. So, unless someone users a power washer, it's all good. I will go along with another poster who questioned the use of tap water as some areas have very hard minerals and that I believe would leave a coating. I believe the system you were looking at recommended the use of cloths diapers to dry. This just makes good sense. 09:58 AM 10/6/2009, you wrote: >I wonder what physical or chemical process occurs >while the vinyl 'heals'. What is it 'healing' from?

Concerning the vacuum, I guess it depends on the strength of the vacuum.  Some machines, like the VPI Typhoon, have a very powerful vacuum.  In fact, the Library of Congress uses a few of these for their records.

Jayson, If you are concerned you can use a filter with the system.  The other arguments against vacuum cleaning is that it does not actually remove all of the dirt from the landings and in effect dries it further.  If you are interested in more information please contact George Merrill.  Hi is a very good person, honest and has also done a lot of research in this area.

One of the claims for the GEM Dandy is that the vacuum dries off the surface water before it has had a chance to suck off all contaminants and dirt. It's a good sales pitch. Be that as it may, I don't think that the concern you raise is a problem. What I do perceive as a disadvantage is the purely manual operation. Never done it, of course, but reading the blurb, it seems to me like a lot of work. I am toying with the idea of building one myself and making it fully automatic. It will still take a few minutes per record, but once I push a button, it will go through the whole process on its own.

It's rather the process of washing that puts a strain on the playing surface. Even for RCMs like VPI, they recommend only a few revolutions per direction as more necessarily doesn't mean better. Running hours of water on a record it by no means going to damage it, although it isn't going to guarantee effective dirt removal. Most RCMs employ some means of dirt removal, some aim an angular jet of water, some use a brush - it differs. But running a record multiple times through a machine is definitely something I have never heard anyone recommend. A single, effective cleaning cycle is definitely important and this is where machines like the VPI 16 or 17 justify their price.

To: "Talk about Nakamichi Cassette Decks" Date: Wednesday, October 7, 2009, 12:22 AM You bring up a good point Ron because water isn't a corrosive, it's rather inert unless outside forces change the molecular structure. Now, on to healing. I recall many, many decades ago there were these devices that you would attach to the player deck and there were be a spray of water into the groove before the stylus and a vacuum afterwards. The thought was that the friction of the stylus in the groove would heat up the vinyl causing a slight reconfiguration of the groove walls.  I believe these devices came out after the introduction of the 120g flaccid LPs as I would like to call them. Any record cleaning system would have been tested to make sure the action of cleaning the groove was considered 'non-destructive'. I'm with you, cleaning with water for hours and hours would do no harm to an vinyl under normal water pressure.  So, unless someone users a power washer, it's all good. I will go along with another poster who questioned the use of tap water as some areas have very hard minerals and that I believe would leave a coating.  I believe the system you were looking at recommended the use of cloths diapers to dry.  This just makes good sense. 09:58 AM 10/6/2009, you wrote: I wonder what physical or chemical process occurs while the vinyl 'heals'. What is it 'healing' from? How long does 'healing' take? Also, I understand how the stylus jumps around in the groove -- thus damaging it -- when VTF is too low. But how is that related to 'excessive' cleaning? The water pressure is nowhere near stylus pressure and water isn't quite as hard as diamond. The water doesn't remove any vinyl at all. It stands to reason that  no vinyl will be removed even if the record is washed for hours and hours. Inquiring minds wish to know... -- Ron Bala Ganesh Chandra wrote: Hi Dan, That is something that I would not recommend. Between cleans, you have to give time for the record playing surface to 'heal'. Because the groove walls are very delicate, excessive cleaning will damage your records just as much as very light tracking styli would. I would suggest gradual cleaning and regular playing to slowly bring the dirt out. The VPI itself is awesome. I use traditional hand washing techniques with the VPI, and the result is a stunningly quiet backdrop.

We were hitting the used record stores and buying boat-loads of used vinyl. We would rather spend our "mad-money" on music than on $70/gallon cleaning fluid. We had a chemist friend analyze the commercial juice and found the composition. I'll have to look up the exact ratios but it is basically ~ 70% Deionized water, 30% CP Isopropyl Alcohol, and 2-drops/gallon of a super pure surfactant. The first two are easily obtainable from a chemical supply house. The last was tough to get. My doctor friend managed to pull some strings and get a sample from the manufacturer. he has since moved across the country but I'll try to contact him and find out the name of it. We were using Kodak Photo-Flow but did feel that we noticed quieter surfaces when we got the super-surfactant. And yes, we definitely could hear noise from deposits from tap water. I personally am really happy with a vacuum record cleaning machine. I chose the Nitty Gritty years ago since I liked the idea of not flipping my record over and putting the freshly cleaned side on a platter that had dust on it from the dirty side. There are advantages to both designs however. The platter designs allow you to "scrub" the surface with more vigor. Happy cleaning!

Kevin, Ron and Dan: I am concerned about one thing with this GEM Dandy RCM system - it uses tap water as a rinse. Tap water contains various amounts of microscopic residue, deposits, minerals, etc. which cannot be healthy for a record groove. As you know, other RCMs on the market use vacuum to soak up the cleaning solution and therefore do not need to be rinsed off. Also, all cleaning solutions use distilled or some form of filtered water as a base (not regular tap water) for this very reason.

I understand Dan cleaned the record with the GEM Dandy and, since the record was still noisy, followed with a VPI vacuum cleaner. . Upon careful listening, I couldn't tell for sure which side was also cleaned with the VPI. As received, the record was very noisy, fit to be discarded. Noise was lowered with manual cleaning. It was further reduced by Dan's treatments, but it's not uniform across either side (some sections are completely noise free). Overall, it's no longer a serious fault. More significant and what made me decide to get the GEM Dandy RCM is the easily audible sonic improvement (manual cleaning never did this). Obviously, in severe cases, further cleanings -- regardless of method -- result in further improvement. I am not sure where lies the point of diminishing returns. I'll know more after I get the RCM and use it for a while. -- Ron Kevin Fetner wrote: Ron, I'm a little confused by your post.

To: Talk about Nakamichi Cassette Decks Message-ID: <4AC76719.3040909 at verizon.net> Content-Type: text/plain; charset="iso-8859-1" Until now, I have never had a chance to made a 'before and after' comparison of RCM (Record Cleaning Machine) cleaned records. I have listened to RCM cleaned records (sounded OK, I guess), without knowing what effect, exactly, the cleaning made. I have cleaned records by hand, using the Rat Shack solution and grease elbow many times, with mixed results. The cleaning invariably did improve noise, but never completely removed it. . Recently, a list member (thanks, again, Dan) has generously offered to RCM clean a couple of records for me. I sent him two used records that I bought for a buck a piece. Both had been seriously attacked by mold and had very high surface noise (smelled it, too). After several hand cleanings, the DG record background noise was almost -- but not quite -- gone, but sound remained muffled and distorted. The Columbia record noise level was also improved, but not to an acceptable level. Both records were taken out of the 'sell, give or throw away' pile, as I expected to never listen to them again. Dan cleaned both records. The DG record was cleaned with the G.E.M. Dandy water pressure machine (with no vacuum solution removal). The Columbia record was also cleaned with a VPI machine, after the water pressure RCM failed to remove all noise. Results: the DG record background noise was almost (say, 99%) eliminated. The muffled, distorted sound became good to very good, except for full orchestral passages, where I can now hear some groove damage of the kind that occurs when a record is repeatedly played with a very low compliance cartridge or with a worn stylus. Before, this was completely swamped by the constant poor sonics. The Columbia record, after all the repeated cleanings, still has some surface noise left. I'd say 90% was removed. Sound is easily much better. In fact, it's surprisingly good. Results of the test: first, I have added both records to my collection, as quite acceptable for future listening. Second, I put in an order for the G.E.M Dandy RCM. It's $149. I'd like to publicly thank Dan for making this experiment happen. -- Ron -------------- next part -------------- An HTML attachment was scrubbed...

Here goes: (1) GEM is cheaper, by over 1/2 (2) GEM appears crude (3) Cleaning with the GEM is 5 to 10 min/lp (4) VPI is more convenient less then 5 min/lp (5) VPI requires less working area (6) VPI is very loud (7) GEM IMHO is more effective cleaner in a non scientific side-by-side comparison I would not put very dirty records on the VPI (as a result of water damaged) that could clog the vacuum For tough records I not only clean multiple times but also use a nylon record cleaning brush to work the cleaning fluid and have never experienced damage in fact the opposite just a better sounding record. With respect to groove/wall damage my neighbor had told me that one should play a record at most once a day because of the PSI exerted on the lp from the needle. I have not heard this with respect to cleaning except in this forum but am interested in more info.

To: Talk about Nakamichi Cassette Decks Message-ID: <709924.34492.qm at web55102.mail.re4.yahoo.com> Content-Type: text/plain; charset="iso-8859-1" Kevin, Ron and Dan: I am concerned about one thing with this GEM Dandy RCM system - it uses tap water as a rinse.  Tap water contains various amounts of microscopic residue, deposits, minerals, etc. which cannot be healthy for a record groove. As you know, other RCMs on the market use vacuum to soak up the cleaning solution and therefore do not need to be rinsed off.  Also, all cleaning solutions use distilled or some form of filtered water as a base (not regular tap water) for this very reason.   Jayson Jayson, I've been using a simple water based record playback system for years. There are some caveats  with this system, but they are huge. This is what I've read: 1) Water playback should ONLY be used with distilled water. 2) Water playback drives the dirt deeper into the grooves. 3) Water will attack some of the stylus glues. 4) Water playback must be used every time you play a record as it does not leave the record 'clean' for dry playback. I can attest that #4 is true. I would assume that the folks who claim #2 is true, have looked at grooves with an electron microscope after water playback. If not, they are guessing. #1 is true because I used to use tap water and after the record dried, you could see the mineral deposits. There are other problems too....like not drying your records after playing and promoting mold inside the record sleeve, in humid climates etc. I don't know for sure about #3, but I know that the glues they use now for needles are very stout and would suspect that water effect is negligible on them. In any event, I've wanted to get away from the water playback system for yrs and have been closely studying RCM's. There is a lot of snob appeal going on in them, just as in HiFi in general. Snob appeal for the most part is nothing based in fact, but in ego. For example, using the 'lowly' KAB EV-1 RCM and supplying your own vacuum, I can't see where the more expensive machines have that one beat in actual cleaning. I would just like to play a record side without having to worry about noise and the needle clogging for once. I would spring for a expensive machine, if it could be proved to me that more is better in this case. Otherwise, I'll focus my attention on the KAB and the Dandy principles. As far as the G.E.M. Dandy using tap water, I think the suggestion of using distilled water for the final rinse and a microfiber cloth is sound. I doubt the device would 'drive' tap water into the grooves to the point where a distilled rinse wouldn't flush it all out.

I don't have the schematic for this deck but it sounds like it may have a microprocessor. If so it will have a 5V supply. If you measure the supply and it is low, it's a good idea to check it with an oscilloscope, for AC ripple or noise on the supply. A bad cap in the supply can cause this. If the supplies are ok, next check the transport. If a belt is slipping, the mode switch that tells the microprocessor what position the transport is in, could be in the wrong position. Locate the motor that actually moves the transport (not the flywheel or the reels) and move it with the power on. It may have a bad spot in the motor and get it started.

IF I recall correctly I know at one time it was recommended to "rest" vinyl after playing (instead of immediately replaying an album) due to the force and friction of the stylus on the grooves. I "think" Bala may be referring to this and the research seemed to favor the idea of not immediately re-playing and let the grooves re-cover from the stress and heat. I have never left vinyl and retained it since I started in the 60's. I am pretty amazed at how well it holds up. I did not get a record cleaner (SOTA) until the 90's. I would not be without one. I also am a huge fan of LAST products and treat all my vinyl with their preservative. In any event, if it comes to digital or vinyl, in my house, no contest, vinyl rules. I do like the convenience of cd's and play them and I have to say some SACD's are pretty damn impressive.

I have heard this many times and strongly suspect it's a myth. First, because I have played a record repeatedly many times and never heard degradation. Second, because of the basic theory of material science, taught in schools all over the world, that's considered an old hat axiom by now. As a piece material is stressed (say, by stretching) it altars its dimension, more or less linearly with the stressing force. If the stress force is removed, the material returns to its former size. This is called elastic deformation. However, if the stress force is increased, a point is reached where the dimensional change abruptly becomes non-linear. If the force is then removed, the material does not revert to it's former size. This is referred to as plastic deformation. Plastic deformation is not recoverable, as it's caused by permanent changes to the material molecular structure. The stress of a stylus pressed against a groove is extremely high, due to the tiny contact area (pressure equals force over area). It is safe to assume that groove deformation does take place. However, as long as it's elastic, no damage is done. (As an aside: that's why I am a great believer in high compliance cartridges that allow low VTF. The lower the stress, the happier will the record be). Some say that the groove requires much time to return to its former shape after elastically deformed. I kinda doubt it. First, for the life of me, I cannot recall time was mentioned in any textbook on the subject. Second, any visible elastic deformation (rubber band, spring, a sheet of plywood or a record as a whole), the material recovers almost instantaneously. Finally, it is not clear why audio phanatics chose a day (24 hours) as the required wait time -- no one could ever explain it. Why not 24 minutes, 24 seconds, or even 24 milliseconds? So, by all means, any that feel the need to wait are welcome to their opinions. I will continue to listen to the same record as many times as I fancy. If I ever hear deterioration, I will be sure to post about it here, in large print.

Not sure if recalibrating them would help. In any case it seems too hard to do so what I do is after level/bias setting I take a mono source, preferably something with a high hiss like a historical recording, and I switch the mono/stereo button back and forth on the amp while setting the record balance on the deck. Once there is no difference between the stereo and mono mode I figure I got the balance right. On my deck the balance setting is correct at quater to eleven. Suppose one could set the level higher on the left channel while calibrating but I'm not sure if that's a good idea. A friend of mine has the same problem with his 582, seems like it's inherent with these decks.

My 582 has a similar issue, but not exactly the same... so I will piggy-back on this 582 post. My 582 has a stronger right channel when I record, and the left VU meter seems more sensitive. After I've set the bias/level for the particular tape being used, I must adjusting the recording balance just to the right of the 11 o'clock position or I end up with a very imbalanced recording. The VU's look relatively close at that point and playback on other units (as well as the 582) results in pretty close to perfect balance at that point. I'd say its more of a nuisance than a real "problem" but the deck is so nice that I'd really like to have it at 100%. Any ideas who can fix this and roughly what it would cost? I'm 97% sure that a tweak of this nature is beyond my abilities.. Thanks in advance for any help.

This causes the grooves to melt, and placing the stylus in those grooves again without waiting causes prematurate wear. You should wait at least an hour to play one side again, but if you can wait more time, that would be preferred.

We were hitting the used record stores and buying boat-loads of used vinyl. We would rather spend our "mad-money" on music than on $70/gallon cleaning fluid. We had a chemist friend analyze the commercial juice and found the composition. I'll have to look up the exact ratios but it is basically ~ 70% Deionized water, 30% CP Isopropyl Alcohol, and 2-drops/gallon of a super pure surfactant. The first two are easily obtainable from a chemical supply house. The last was tough to get. My doctor friend managed to pull some strings and get a sample from the manufacturer. he has since moved across the country but I'll try to contact him and find out the name of it. We were using Kodak Photo-Flow but did feel that we noticed quieter surfaces when we got the super-surfactant. And yes, we definitely could hear noise from deposits from tap water. I personally am really happy with a vacuum record cleaning machine. I chose the Nitty Gritty years ago since I liked the idea of not flipping my record over and putting the freshly cleaned side on a platter that had dust on it from the dirty side. There are advantages to both designs however. The platter designs allow you to "scrub" the surface with more vigor. Happy cleaning!

Kevin, Ron and Dan: I am concerned about one thing with this GEM Dandy RCM system - it uses tap water as a rinse. Tap water contains various amounts of microscopic residue, deposits, minerals, etc. which cannot be healthy for a record groove. As you know, other RCMs on the market use vacuum to soak up the cleaning solution and therefore do not need to be rinsed off. Also, all cleaning solutions use distilled or some form of filtered water as a base (not regular tap water) for this very reason.

I understand Dan cleaned the record with the GEM Dandy and, since the record was still noisy, followed with a VPI vacuum cleaner. . Upon careful listening, I couldn't tell for sure which side was also cleaned with the VPI. As received, the record was very noisy, fit to be discarded. Noise was lowered with manual cleaning. It was further reduced by Dan's treatments, but it's not uniform across either side (some sections are completely noise free). Overall, it's no longer a serious fault. More significant and what made me decide to get the GEM Dandy RCM is the easily audible sonic improvement (manual cleaning never did this). Obviously, in severe cases, further cleanings -- regardless of method -- result in further improvement. I am not sure where lies the point of diminishing returns. I'll know more after I get the RCM and use it for a while. -- Ron Kevin Fetner wrote: Ron, I'm a little confused by your post.

To: Talk about Nakamichi Cassette Decks Message-ID: <4AC76719.3040909 at verizon.net> Content-Type: text/plain; charset="iso-8859-1" Until now, I have never had a chance to made a 'before and after' comparison of RCM (Record Cleaning Machine) cleaned records. I have listened to RCM cleaned records (sounded OK, I guess), without knowing what effect, exactly, the cleaning made. I have cleaned records by hand, using the Rat Shack solution and grease elbow many times, with mixed results. The cleaning invariably did improve noise, but never completely removed it. . Recently, a list member (thanks, again, Dan) has generously offered to RCM clean a couple of records for me. I sent him two used records that I bought for a buck a piece. Both had been seriously attacked by mold and had very high surface noise (smelled it, too). After several hand cleanings, the DG record background noise was almost -- but not quite -- gone, but sound remained muffled and distorted. The Columbia record noise level was also improved, but not to an acceptable level. Both records were taken out of the 'sell, give or throw away' pile, as I expected to never listen to them again. Dan cleaned both records. The DG record was cleaned with the G.E.M. Dandy water pressure machine (with no vacuum solution removal). The Columbia record was also cleaned with a VPI machine, after the water pressure RCM failed to remove all noise. Results: the DG record background noise was almost (say, 99%) eliminated. The muffled, distorted sound became good to very good, except for full orchestral passages, where I can now hear some groove damage of the kind that occurs when a record is repeatedly played with a very low compliance cartridge or with a worn stylus. Before, this was completely swamped by the constant poor sonics. The Columbia record, after all the repeated cleanings, still has some surface noise left. I'd say 90% was removed. Sound is easily much better. In fact, it's surprisingly good. Results of the test: first, I have added both records to my collection, as quite acceptable for future listening. Second, I put in an order for the G.E.M Dandy RCM. It's $149. I'd like to publicly thank Dan for making this experiment happen. -- Ron _________________________________________________________________ Hotmail: Free, trusted and rich email service. http://clk.atdmt.com/GBL/go/171222984/direct/01/ -------------- next part -------------- An HTML attachment was scrubbed...

Thus, here is a fresh one from yesterday evening with my ZX7: I planned to record a tape, so put the deck in REC/Standby mode, pushed in the AZ/Calibration button in order to be able to turn the two azimuth knobs but the deck DID NOT swith in REC mode (the transport does not start to run). Afterwards, I tried to record in the normal way (avoiding the calibration process) so REC/STANDBY, pushed in PLAY, it runs but the REC MUTE ligth stays ON and the tape is not totally erased Back to the calibration processs, i verified that the two tones are there, I can see them on the scale meters when switching in SOURCE mode and hiting LEVEL AND BIAS buttons. So, according to what I have red here, I guess something is wrong in the Bias ascillator? orange caps?

They are similar in principle to the Nitty Gritty and VPI but they have some interesting features (as well as being cheaper than the other two! First, the wetting is done on the top, using a carbon fibre brush, so as to get into the grooves. Then the surface is dried by a vacuum riding just above the record surface, minimising the loss of fluid from the record surface. The record does have to be turned over. However it does not sit on a platter as such but is held in place by a clamp so that the cleaned surface underneath is not contaminated. The Moth machine used to (may still do) come in a kit form, if you wished to have it that way. I am not sure of the prices now but the kit version was about 25-33% cheaper than the made up one. I forget how much they cost, but I got mine several years ago for about £300-£350, I think - might have been less. One bad thing about it is it’s got a noisy vacuum motor! Not too clever in a confined space, rather like those small hand held vacuums for vehicle upholstery!! The solution I use is one that Moth recommend for making up. Don’t ask me what it is because I can’t darn well find the recipe! However, the basic ingredients are much as yours, Doug – distilled or deionised water (the former is preferred by them), Isopropyl and small quantity photographic wetting agent (which I presume is the same or similar to what you called a “super pure surfactant”.) The latter is important, I suppose, because in making the water wetter it is more likely to penetrate into the bottom of the fine grooves of records, which might otherwise be missed due to pure water’s surface tension. With regard to the water, I have been told the ice that forms inside a domestic freezer is as good as distilled water when it is melted. Anyone know if this is true as it would be a nice way to reduce the cost incurred buying distilled water from the auto parts shop! Graham From: naktalk-bounces at naks.com [mailto:naktalk-bounces at naks.com] On Behalf Of Doug Guth Sent: Wednesday, October 07, 2009 12:47 PM To: Talk about Nakamichi Cassette Decks Subject: [naktalk] Record Cleeaning Years ago a Neurologist customer and myself were interested in making our own record cleaning solution. We were hitting the used record stores and buying boat-loads of used vinyl. We would rather spend our "mad-money" on music than on $70/gallon cleaning fluid. We had a chemist friend analyze the commercial juice and found the composition. I'll have to look up the exact ratios but it is basically ~ 70% Deionized water, 30% CP Isopropyl Alcohol, and 2-drops/gallon of a super pure surfactant. The first two are easily obtainable from a chemical supply house. The last was tough to get. My doctor friend managed to pull some strings and get a sample from the manufacturer. he has since moved across the country but I'll try to contact him and find out the name of it. We were using Kodak Photo-Flow but did feel that we noticed quieter surfaces when we got the super-surfactant. And yes, we definitely could hear noise from deposits from tap water. I personally am really happy with a vacuum record cleaning machine. I chose the Nitty Gritty years ago since I liked the idea of not flipping my record over and putting the freshly cleaned side on a platter that had dust on it from the dirty side. There are advantages to both designs however. The platter designs allow you to "scrub" the surface with more vigor. Happy cleaning!

I just finished restoring a Dragon for a very good customer of mine. When I sent it back to him, it arrived smashed, despite being fully padded and DOUBLE BOXED. Even though the deck was damaged, it is repairable -- but I need the blue Auto Azimuth cable! This is a flat blue cable that runs from the deck's Auto Azimuth module located behind the tape transport and runs to the deck's playback head assembly. The cable on my customer's Dragon was completely cut into two pieces. DOES ANYONE HAVE THIS BLUE CABLE? I will pay ANY reasonable price for it.

While not delving too much into the specifics of material deformation to the irk of the moderators, elastic deformation is mostly almost instant. But, that is by no means complete. I remember a very detailed mathematical paper published in the 70s about stylus force on the groove and the immense force given the macro dimensions are simply amazing. I have also seen prove of how even the most well cared and carefully played records suffer wear, when I listen to a mint (not re-issued) copy of the same album. It's simply amazing and it makes me realize how delicate records can be. Of course by exposing a record to running water is not going to make droop in your hands, Dali style to exhibit deformation. But given the small dimensions of the grooves, and the sensitivities of today's styli, it seems only prudent to be a little bit more careful and avoid too much cleaning or playing of our precious LPs. It's not my intention to snide you and I have respect for your knowledge and experience. I know you are well capable of friendly posts Ron, so lets keep the respect there for each other.

You may remember the business of elastic vs. plastic deformation and the rest of that stuff from your own learning. The only deformation (if any) after cleaning under a water jet from a kitchen faucet can be elastic, so I wondered where you derived the idea of a  record needing to 'heal' and/or 'recover' after cleaning.

The generality "at least 1 ton per sqare inch" is meaningless. I have no idea what temperature rise occurs at the contact point, but that depends on the friction, which, for a diamond riding on vinyl, is very low. Nowhere have I seen results of reliable temperature measurements. Have you? I kinda doubt the vinyl melts or even softens. If it did, it would permanently deform, causing distortion after the very first play, that I have never heard.

Group, I really do not have any scientific results only results of my experience for the past year with both the GEM and VPI. Here goes: (1) GEM is cheaper, by over 1/2 (2) GEM appears crude (3) Cleaning with the GEM is 5 to 10 min/lp (4) VPI is more convenient less then 5 min/lp (5) VPI requires less working area (6) VPI is very loud (7) GEM IMHO is more effective cleaner in a non scientific side-by-side comparison I would not put very dirty records on the VPI (as a result of water damaged) that could clog the vacuum For tough records I not only clean multiple times but also use a nylon record cleaning brush to work the cleaning fluid and have never experienced damage in fact the opposite just a better sounding record. With respect to groove/wall damage my neighbor had told me that one should play a record at most once a day because of the PSI exerted on the lp from the needle.

I was informed that the cloudy areas were the impurities in the ice. I don't know how true it is but I have also heard other theories like boiling the water before you make ice. It all sounds like a PITA to me. Why not use distilled water? Just don't buy it in auto parts stores, instead try large grocery stores or Walmart type stores. I 'v a large boat with several batteries that often thirst for distilled h2o which I buy at my local walmart for aprox. 89 cents per gallon and I bet that's a lot less than the auto parts emporiums.

They are similar in principle to the Nitty Gritty and VPI but they have some interesting features (as well as being cheaper than the other two! First, the wetting is done on the top, using a carbon fibre brush, so as to get into the grooves. Then the surface is dried by a vacuum riding just above the record surface, minimising the loss of fluid from the record surface. The record does have to be turned over. However it does not sit on a platter as such but is held in place by a clamp so that the cleaned surface underneath is not contaminated. The Moth machine used to (may still do) come in a kit form, if you wished to have it that way. I am not sure of the prices now but the kit version was about 25-33% cheaper than the made up one. I forget how much they cost, but I got mine several years ago for about £300-£350, I think - might have been less. One bad thing about it is it’s got a noisy vacuum motor! Not too clever in a confined space, rather like those small hand held vacuums for vehicle upholstery!! The solution I use is one that Moth recommend for making up. Don’t ask me what it is because I can’t darn well find the recipe! However, the basic ingredients are much as yours, Doug – distilled or deionised water (the former is preferred by them), Isopropyl and small quantity photographic wetting agent (which I presume is the same or similar to what you called a “super pure surfactant”.) The latter is important, I suppose, because in making the water wetter it is more likely to penetrate into the bottom of the fine grooves of records, which might otherwise be missed due to pure water’s surface tension. With regard to the water, I have been told the ice that forms inside a domestic freezer is as good as distilled water when it is melted. Anyone know if this is true as it would be a nice way to reduce the cost incurred buying distilled water from the auto parts shop!

I have heard this many times and strongly suspect it's a myth. First, because I have played a record repeatedly many times and never heard degradation. Second, because of the basic theory of material science, taught in schools all over the world, that's considered an old hat axiom by now. As a piece material is stressed (say, by stretching) it altars its dimension, more or less linearly with the stressing force. If the stress force is removed, the material returns to its former size. This is called elastic deformation. However, if the stress force is increased, a point is reached where the dimensional change abruptly becomes non-linear. If the force is then removed, the material does not revert to it's former size. This is referred to as plastic deformation. Plastic deformation is not recoverable, as it's caused by permanent changes to the material molecular structure. The stress of a stylus pressed against a groove is extremely high, due to the tiny contact area (pressure equals force over area). It is safe to assume that groove deformation does take place. However, as long as it's elastic, no damage is done. (As an aside: that's why I am a great believer in high compliance cartridges that allow low VTF. The lower the stress, the happier will the record be). Some say that the groove requires much time to return to its former shape after elastically deformed. I kinda doubt it. First, for the life of me, I cannot recall time was mentioned in any textbook on the subject. Second, any visible elastic deformation (rubber band, spring, a sheet of plywood or a record as a whole), the material recovers almost instantaneously. Finally, it is not clear why audio phanatics chose a day (24 hours) as the required wait time -- no one could ever explain it. Why not 24 minutes, 24 seconds, or even 24 milliseconds? So, by all means, any that feel the need to wait are welcome to their opinions. I will continue to listen to the same record as many times as I fancy. If I ever hear  deterioration, I will be sure to post about it here, in large print.

By holding the brush at about 45 degrees to the record's playing surface, you should be able to work up a lather. Work in short strokes to help work the dirt out of the grooves. It usually is ok if the lable gets wet, although try not to soak them. After thoroughly rinsing both sides in running water, set them up to dry. The only reason I dry them is because, if the other side has water, it will wet the cork mat of the VPI. The next stage, as you do, is to use the VPI for a thorough and deep cleaning. I stick to the recommended three revolutions per direction  and the one revolution on vaccuum suggested by VPI. I suggest you use common glycerin based detergents, but avoid any that are meant for oil and grease removal.

You can see it on the photo of the service manual, attached to this email. The respective knob is F03. My question is: This knob is it the same part like in the Nakamichi ZX680 ? This deck has the pitch control as well. The knob looks exactly the same as the knob of the 1000 ZXL. My second question is: Can anyone sell me such a knob? Or, can anyone sell me a deck ZX680, it does not need to be functioning, I would only buy it because of this knob. The other parts I would offer as spare parts to this community here.

Group, I really do not have any scientific results only results of my experience for the past year with both the GEM and VPI. Here goes: (1) GEM is cheaper, by over 1/2 (2) GEM appears crude (3) Cleaning with the GEM is 5 to 10 min/lp (4) VPI is more convenient less then 5 min/lp (5) VPI requires less working area (6) VPI is very loud (7) GEM IMHO is more effective cleaner in a non scientific side-by-side comparison I would not put very dirty records on the VPI (as a result of water damaged) that could clog the vacuum For tough records I not only clean multiple times but also use a nylon record cleaning brush to work the cleaning fluid and have never experienced damage in fact the opposite just a better sounding record. With respect to groove/wall damage my neighbor had told me that one should play a record at most once a day because of the PSI exerted on the lp from the needle.  I have not heard this with respect to cleaning except in this forum but am interested in more info.

I just finished restoring a Dragon for a very good customer of mine. When I sent it back to him, it arrived smashed, despite being fully padded and DOUBLE BOXED. Even though the deck was damaged, it is repairable -- but I need the blue Auto Azimuth cable! This is a flat blue cable that runs from the deck's Auto Azimuth module located behind the tape transport and runs to the deck's playback head assembly. The cable on my customer's Dragon was completely cut into two pieces. DOES ANYONE HAVE THIS BLUE CABLE? I will pay ANY reasonable price for it.

Wikipedia: "various pathogens accumulate in the water, particularly due to its stagnancy, including fungal spores; unlike in distilled water, the water is not boiled, which would kill pathogens (including bacteria)" I've also noticed that old ice cubes can have a funky smell (pathogens?). Wikipedia again: "Distilled water is water that has virtually all of its impurities removed through distillation. Distillation involves boiling the water and then condensing the steam into a clean container, leaving most if not all solid contaminants behind." This distillation does not happen in a refrigerator/dehumidifier... I use water from the dehumidifier on the outside garden.

We were hitting the used record stores and buying boat-loads of used vinyl. We would rather spend our "mad-money" on music than on $70/gallon cleaning fluid. We had a chemist friend analyze the commercial juice and found the composition. I'll have to look up the exact ratios but it is basically ~ 70% Deionized water, 30% CP Isopropyl Alcohol, and 2-drops/gallon of a super pure surfactant. The first two are easily obtainable from a chemical supply house. The last was tough to get. My doctor friend managed to pull some strings and get a sample from the manufacturer. he has since moved across the country but I'll try to contact him and find out the name of it. We were using Kodak Photo-Flow but did feel that we noticed quieter surfaces when we got the super-surfactant. And yes, we definitely could hear noise from deposits from tap water. I personally am really happy with a vacuum record cleaning machine. I chose the Nitty Gritty years ago since I liked the idea of not flipping my record over and putting the freshly cleaned side on a platter that had dust on it from the dirty side. There are advantages to both designs however. The platter designs allow you to "scrub" the surface with more vigor. Happy cleaning!

So, should indeed be collected immediately. Left in the open metal container, the water will soon accumulate enough contaminants (that musty smell is fungus) to become dirtier than tap water. Even then, I am sure it's not as pure as correctly distilled water, so I would not drink or use it for medical purposes, but I have been using it for years for normal household chores, for which I would probably use tap water if I didn't have a dehumidifier. -- Ron fripp_em wrote: > I hope you don't drink the water from your dehumidifier:-) I've noticed in musty basements that water from a dehumidifier can have a funky smell.

Then I always follow up with LAST archival record treatment.  The Steam cleaning methos seems to be working wonders for most people, but I myself have not tried this, although I do own a very good Steam Cleaner.  The VPI RCM has been nothing short of wonderful for me. And different cleaners seem to work better for different condition records, such as new, or old records, or very dirty records, using a good pre-cleaner. you may want to look into the Steam Cleaning method on Audiogon, Audio Asylum, or Audio Karma.  Best, Ray ----- Original Message ----- From: naktalk-request at naks.com To: naktalk at naks.com Sent: Thursday, October 8, 2009 9:35:11 AM GMT -05:00 US/Canada Eastern Subject: Naktalk Digest, Vol 80, Issue 8 Send Naktalk mailing list submissions to         naktalk at naks.com To subscribe or unsubscribe via the World Wide Web, visit         http://www.naks.com/mailman/listinfo/naktalk or, via email, send a message with subject or body 'help' to         naktalk-request at naks.com You can reach the person managing the list at         naktalk-owner at naks.com When replying, please edit your Subject line so it is more specific than "Re: Contents of Naktalk digest..."

Here goes: (1) GEM is cheaper, by over 1/2 (2) GEM appears crude (3) Cleaning with the GEM is 5 to 10 min/lp (4) VPI is more convenient less then 5 min/lp (5) VPI requires less working area (6) VPI is very loud (7) GEM IMHO is more effective cleaner in a non scientific side-by-side comparison I would not put very dirty records on the VPI (as a result of water damaged) that could clog the vacuum For tough records I not only clean multiple times but also use a nylon record cleaning brush to work the cleaning fluid and have never experienced damage in fact the opposite just a better sounding record. With respect to groove/wall damage my neighbor had told me that one should play a record at most once a day because of the PSI exerted on the lp from the needle.  I have not heard this with respect to cleaning except in this forum but am interested in more info.

However, by now I have learned enough to question what seems to be a myth that conflicts with previously assimilated knowledge. I do not refute, just question. For example, I am not a mechanical engineer, but did take Materials 101, that included behaviour of materials under stress. You may remember the business of elastic vs. plastic deformation and the rest of that stuff from your own learning. The only deformation (if any) after cleaning under a water jet from a kitchen faucet can be elastic, so I wondered where you derived the idea of a  record needing to 'heal' and/or 'recover' after cleaning. Some factual data would have been welcome, in place of a snide remark concerning my age and experience.

There are some caveats� with this system, but they are huge. This is what I've read: 1) Water playback should ONLY be used with distilled water. 2) Water playback drives the dirt deeper into the grooves. 3) Water will attack some of the stylus glues. 4) Water playback must be used every time you play a record as it does not leave the record 'clean' for dry playback. I can attest that #4 is true. I would assume that the folks who claim #2 is true, have looked at grooves with an electron microscope after water playback. If not, they are guessing. #1 is true because I used to use tap water and after the record dried, you could see the mineral deposits. There are other problems too....like not drying your records after playing and promoting mold inside the record sleeve, in humid climates etc. I don't know for sure about #3, but I know that the glues they use now for needles are very stout and would suspect that water effect is negligible on them. In any event, I've wanted to get away from the water playback system for yrs and have been closely studying RCM's. There is a lot of snob appeal going on in them, just as in HiFi in general. Snob appeal for the most part is nothing based in fact, but in ego. For example, using the 'lowly' KAB EV-1 RCM and supplying your own vacuum, I can't see where the more expensive machines have that one beat in actual cleaning. I would just like to play a record side without having to worry about noise and the needle clogging for once. I would spring for a expensive machine, if it could be proved to me that more is better in this case. Otherwise, I'll focus my attention on the KAB and the Dandy principles. As far as the G.E.M. Dandy using tap water, I think the suggestion of using distilled water for the final rinse and a microfiber cloth is sound. I doubt the device would 'drive' tap water into the grooves to the point where a distilled rinse wouldn't flush it all out.

I don't have the schematic for this deck but it sounds like it may have a microprocessor. If so it will have a 5V supply. If you measure the supply and it is low, it's a good idea to check it with an oscilloscope, for AC ripple or noise on the supply. A bad cap in the supply can cause this. If the supplies are ok, next check the transport. If a belt is slipping, the mode switch that tells the microprocessor what position the transport is in, could be in the wrong position. Locate the motor that actually moves the transport (not the flywheel or the reels) and move it with the power on. It may have a bad spot in the motor and get it started.

IF I recall correctly I know at one time it was recommended to "rest" vinyl after playing (instead of immediately replaying an album) due to the force and friction of the stylus on the grooves. I "think" Bala may be referring to this and the research seemed to favor the idea of not immediately re-playing and let the grooves re-cover from the stress and heat. I have never left vinyl and retained it since I started in the 60's. I am pretty amazed at how well it holds up. I did not get a record cleaner (SOTA) until the 90's. I would not be without one. I also am a huge fan of LAST products and treat all my vinyl with their preservative. In any event, if it comes to digital or vinyl, in my house, no contest, vinyl rules. I do like the convenience of cd's and play them and I have to say some SACD's are pretty damn impressive.

I have heard this many times and strongly suspect it's a myth. First, because I have played a record repeatedly many times and never heard degradation. Second, because of the basic theory of material science, taught in schools all over the world, that's considered an old hat axiom by now. As a piece material is stressed (say, by stretching) it altars its dimension, more or less linearly with the stressing force. If the stress force is removed, the material returns to its former size. This is called elastic deformation. However, if the stress force is increased, a point is reached where the dimensional change abruptly becomes non-linear. If the force is then removed, the material does not revert to it's former size. This is referred to as plastic deformation. Plastic deformation is not recoverable, as it's caused by permanent changes to the material molecular structure. The stress of a stylus pressed against a groove is extremely high, due to the tiny contact area (pressure equals force over area). It is safe to assume that groove deformation does take place. However, as long as it's elastic, no damage is done. (As an aside: that's why I am a great believer in high compliance cartridges that allow low VTF. The lower the stress, the happier will the record be). Some say that the groove requires much time to return to its former shape after elastically deformed. I kinda doubt it. First, for the life of me, I cannot recall time was mentioned in any textbook on the subject. Second, any visible elastic deformation (rubber band, spring, a sheet of plywood or a record as a whole), the material recovers almost instantaneously. Finally, it is not clear why audio phanatics chose a day (24 hours) as the required wait time -- no one could ever explain it. Why not 24 minutes, 24 seconds, or even 24 milliseconds? So, by all means, any that feel the need to wait are welcome to their opinions. I will continue to listen to the same record as many times as I fancy. If I ever hear  deterioration, I will be sure to post about it here, in large print.

Not sure if recalibrating them would help. In any case it seems too hard to do so what I do is after level/bias setting I take a mono source, preferably something with a high hiss like a historical recording, and I switch the mono/stereo button back and forth on the amp while setting the record balance on the deck. Once there is no difference between the stereo and mono mode I figure I got the balance right. On my deck the balance setting is correct  at quater to eleven. Suppose one could set the level higher on the left channel while calibrating but I'm not sure if that's a good idea. A friend of mine has the same problem with his 582, seems like it's inherent with these decks.   Peter   From: jaetee at tampabay.rr.com To: naktalk at naks.com Subject: RE: [naktalk] 582 VU's and recording imbalance Date: Tue, 6 Oct 2009 09:56:09 -0400 Did anyone reply with a fix for this?   My 582 has a similar issue, but not exactly the same... so I will piggy-back on this 582 post.   My 582 has a stronger right channel when I record, and the left VU meter seems more sensitive.     After I've set the bias/level for the particular tape being used, I must adjusting the recording balance just to the right of the 11 o'clock position or I end up with a very imbalanced recording. The VU's look relatively close at that point and playback on other units (as well as the 582) results in pretty close to perfect balance at that point. I'd say its more of a nuisance than a real "problem" but the deck is so nice that I'd really like to have it at 100%.   Any ideas who can fix this and roughly what it would cost?   I'm 97% sure that a tweak of this nature is beyond my abilities..     Thanks in advance for any help.   JT -----Original Message----- From: naktalk-bounces at naks.com [mailto:naktalk-bounces at naks.com] On Behalf Of Tim Skorick Sent: Friday, September 25, 2009 6:04 PM To: Talk about Nakamichi Cassette Decks Subject: Re: [naktalk] 582 Is the right channel actually 10db louder than the left? -Tim On Thu, Sep 24, 2009 at 10:00 AM, Peter Tanner wrote: Hello Ron, Willy and all   A question about my 582. It works very well but I've noticed that the right meter indicates 10db more than the left one. In other words when I turn the deck on the left meter is at the minimum, -40 db while the right shows -30 db. This could mean that my record and bias calibrations are out as I set both indicators at 0 db. When I record a 400hz signal at 0 db on both channels and I play it back on another deck the right channel is stronger.  Can this be adjusted and if yes how?  Thanks   Peter Microsoft brings you a new way to search the web.

Any water that has a 'smell' is usually the result of a pathogen and the biology attached to that. Unless your fridge is incredibly cleaner than mine, any thawed water from there has an odor. This is a completely different 'animal' than mechanically distilled water. Also, any water stored that is exposed to direct or indirect sunlight will start to form biology (even bottled, distilled water in time). Therefore, I would advise against starting this process with 'free' water from appliances that probably contains much inherent biology-especially as a final rinsing agent.  I routinely search for distilled water at the box stores and it goes for roughly $1/gal on sale. I find that a doable price for even my modest budget. Kevin -------------- next part -------------- An HTML attachment was scrubbed...

Re-melted ice water causes the soundstage to become much to wide and make the bass boom. I have gotten very good results with toilet bowl water but whenever I use it my dog gets very upset. I guess he thinks I'm encroaching on his territory and he starts growling at me, messing the carpets and chewing the leather sofa etc. In order to keep the mutt happy I spend the 98 cents and buy a gallon of distilled water. I find that it gives me better results than any of the other waters (except for toilet water) my dog stays content and happy and my records sound as good as the day I brought them home from the thrift store.

I reckon it's not laboratory grade purity, due to the open metal container, but good enough for car batteries, LP cleaning and the like. -- Ron Graham From: naktalk-bounces at naks.com [mailto:naktalk-bounces at naks.com] On Behalf Of Doug Guth Sent: Wednesday, October 07, 2009 12:47 PM To: Talk about Nakamichi Cassette Decks Subject: [naktalk] Record Cleeaning Years ago a Neurologist customer and myself were interested in making our own record cleaning solution. We were hitting the used record stores and buying boat-loads of used vinyl. We would rather spend our "mad-money" on music than on $70/gallon cleaning fluid. We had a chemist friend analyze the commercial juice and found the composition. I'll have to look up the exact ratios but it is basically ~ 70% Deionized water, 30% CP Isopropyl Alcohol, and 2-drops/gallon of a super pure surfactant. The first two are easily obtainable from a chemical supply house. The last was tough to get. My doctor friend managed to pull some strings and get a sample from the manufacturer. he has since moved across the country but I'll try to contact him and find out the name of it. We were using Kodak Photo-Flow but did feel that we noticed quieter surfaces when we got the super-surfactant. And yes, we definitely could hear noise from deposits from tap water. I personally am really happy with a vacuum record cleaning machine. I chose the Nitty Gritty years ago since I liked the idea of not flipping my record over and putting the freshly cleaned side on a platter that had dust on it from the dirty side. There are advantages to both designs however. The platter designs allow you to "scrub" the surface with more vigor. Happy cleaning!

This has a tendency to rub dirt or worse, scratch records if not cleaned. I use a toothbrush to brush it clean regularly and inspect for any stuck grit or dirt. It's easy to replace them as their held with double-sided tape. Washing the record is effective as it removes oil and any chemicals left behind during the manufacturing process. According to one engineer, chemicals are applied to the vinyl to aid separation from the master during manufacture. I do not know if this causes any harm but I prefer my records to be free of any chemicals and of course oil from fingerprints. A round of washing gets rids of the majority of dirt and oil. The VPI then gets deep into the groove for that really deep cleaning. The real test is when you use very small styli, such as those used by Lyra, they accumulate very little dirt.

Then I always follow up with LAST archival record treatment.  The Steam cleaning methos seems to be working wonders for most people, but I myself have not tried this, although I do own a very good Steam Cleaner.  The VPI RCM has been nothing short of wonderful for me. And different cleaners seem to work better for different condition records, such as new, or old records, or very dirty records, using a good pre-cleaner. you may want to look into the Steam Cleaning method on Audiogon, Audio Asylum, or Audio Karma.  Best, Ray   ----- Original Message ----- From: naktalk-request at naks.com To: naktalk at naks.com Sent: Thursday, October 8, 2009 9:35:11 AM GMT -05:00 US/Canada Eastern Subject: Naktalk Digest, Vol 80, Issue 8 Send Naktalk mailing list submissions to         naktalk at naks.com To subscribe or unsubscribe via the World Wide Web, visit         http://www.naks.com/mailman/listinfo/naktalk or, via email, send a message with subject or body 'help' to         naktalk-request at naks.com You can reach the person managing the list at         naktalk-owner at naks.com When replying, please edit your Subject line so it is more specific than "Re: Contents of Naktalk digest..."

Final resort is to rebuild it.            -- Ron                                  Michael Cole wrote:                                     Hi,             �             I haven't played my 680ZX for a while and when I switched it on this evening I noticed that the VU meters didn't light and there was no led lit above the stop button.� The light in the cassette well and the counter are both lit.� The cassette well door is locked and the door open lever won't depress fully to the open position.             �             I'm at a loss to know what the problem is.� Can anyone help me out?             �             Thanks,             �             Mike                                                                                           -----Inline Attachment Follows----- ========---------------------------------------------------------========= � � � � � Also check out the wiki! http://www.naks.com/wiki ========---------------------------------------------------------========= � � � � � � � � � � � � Naktalk at naks.com mailinglist Maintain your account here: http://www.naks.com/mailman/listinfo/naktalk ========---------------------------------------------------------=========        -------------- next part -------------- An HTML attachment was scrubbed...

My machine has picked up the following problem: When I switch the machine on, the Auto Calibration red indicator light immediately comes on and stays on and the machine does not respond to any commands (ie nothing works), whether a cassette is loaded or not. Could you please comment to the possible cause of my problem, as well as how to fix it. Have a great Nat day!!!

Here goes: (1) GEM is cheaper, by over 1/2 (2) GEM appears crude (3) Cleaning with the GEM is 5 to 10 min/lp (4) VPI is more convenient less then 5 min/lp (5) VPI requires less working area (6) VPI is very loud (7) GEM IMHO is more effective cleaner in a non scientific side-by-side comparison I would not put very dirty records on the VPI (as a result of water damaged) that could clog the vacuum For tough records I not only clean multiple times but also use a nylon record cleaning brush to work the cleaning fluid and have never experienced damage in fact the opposite just a better sounding record. With respect to groove/wall damage my neighbor had told me that one should play a record at most once a day because of the PSI exerted on the lp from the needle.  I have not heard this with respect to cleaning except in this forum but am interested in more info.

However, by now I have learned enough to question what seems to be a myth that conflicts with previously assimilated knowledge. I do not refute, just question. For example, I am not a mechanical engineer, but did take Materials 101, that included behaviour of materials under stress. You may remember the business of elastic vs. plastic deformation and the rest of that stuff from your own learning. The only deformation (if any) after cleaning under a water jet from a kitchen faucet can be elastic, so I wondered where you derived the idea of a  record needing to 'heal' and/or 'recover' after cleaning. Some factual data would have been welcome, in place of a snide remark concerning my age and experience.

There are some caveats� with this system, but they are huge. This is what I've read: 1) Water playback should ONLY be used with distilled water. 2) Water playback drives the dirt deeper into the grooves. 3) Water will attack some of the stylus glues. 4) Water playback must be used every time you play a record as it does not leave the record 'clean' for dry playback. I can attest that #4 is true. I would assume that the folks who claim #2 is true, have looked at grooves with an electron microscope after water playback. If not, they are guessing. #1 is true because I used to use tap water and after the record dried, you could see the mineral deposits. There are other problems too....like not drying your records after playing and promoting mold inside the record sleeve, in humid climates etc. I don't know for sure about #3, but I know that the glues they use now for needles are very stout and would suspect that water effect is negligible on them. In any event, I've wanted to get away from the water playback system for yrs and have been closely studying RCM's. There is a lot of snob appeal going on in them, just as in HiFi in general. Snob appeal for the most part is nothing based in fact, but in ego. For example, using the 'lowly' KAB EV-1 RCM and supplying your own vacuum, I can't see where the more expensive machines have that one beat in actual cleaning. I would just like to play a record side without having to worry about noise and the needle clogging for once. I would spring for a expensive machine, if it could be proved to me that more is better in this case. Otherwise, I'll focus my attention on the KAB and the Dandy principles. As far as the G.E.M. Dandy using tap water, I think the suggestion of using distilled water for the final rinse and a microfiber cloth is sound.

I don't have the schematic for this deck but it sounds like it may have a microprocessor. If so it will have a 5V supply. If you measure the supply and it is low, it's a good idea to check it with an oscilloscope, for AC ripple or noise on the supply. A bad cap in the supply can cause this. If the supplies are ok, next check the transport. If a belt is slipping, the mode switch that tells the microprocessor what position the transport is in, could be in the wrong position. Locate the motor that actually moves the transport (not the flywheel or the reels) and move it with the power on. It may have a bad spot in the motor and get it started.

IF I recall correctly I know at one time it was recommended to "rest" vinyl after playing (instead of immediately replaying an album) due to the force and friction of the stylus on the grooves. I "think" Bala may be referring to this and the research seemed to favor the idea of not immediately re-playing and let the grooves re-cover from the stress and heat. I have never left vinyl and retained it since I started in the 60's. I am pretty amazed at how well it holds up. I did not get a record cleaner (SOTA) until the 90's. I would not be without one. I also am a huge fan of LAST products and treat all my vinyl with their preservative. In any event, if it comes to digital or vinyl, in my house, no contest, vinyl rules. I do like the convenience of cd's and play them and I have to say some SACD's are pretty damn impressive.

I have heard this many times and strongly suspect it's a myth. First, because I have played a record repeatedly many times and never heard degradation. Second, because of the basic theory of material science, taught in schools all over the world, that's considered an old hat axiom by now. As a piece material is stressed (say, by stretching) it altars its dimension, more or less linearly with the stressing force. If the stress force is removed, the material returns to its former size. This is called elastic deformation. However, if the stress force is increased, a point is reached where the dimensional change abruptly becomes non-linear. If the force is then removed, the material does not revert to it's former size. This is referred to as plastic deformation. Plastic deformation is not recoverable, as it's caused by permanent changes to the material molecular structure. The stress of a stylus pressed against a groove is extremely high, due to the tiny contact area (pressure equals force over area). It is safe to assume that groove deformation does take place. However, as long as it's elastic, no damage is done. (As an aside: that's why I am a great believer in high compliance cartridges that allow low VTF. The lower the stress, the happier will the record be). Some say that the groove requires much time to return to its former shape after elastically deformed. I kinda doubt it. First, for the life of me, I cannot recall time was mentioned in any textbook on the subject. Second, any visible elastic deformation (rubber band, spring, a sheet of plywood or a record as a whole), the material recovers almost instantaneously. Finally, it is not clear why audio phanatics chose a day (24 hours) as the required wait time -- no one could ever explain it. Why not 24 minutes, 24 seconds, or even 24 milliseconds? So, by all means, any that feel the need to wait are welcome to their opinions. I will continue to listen to the same record as many times as I fancy. If I ever hear  deterioration, I will be sure to post about it here, in large print.

Not sure if recalibrating them would help. In any case it seems too hard to do so what I do is after level/bias setting I take a mono source, preferably something with a high hiss like a historical recording, and I switch the mono/stereo button back and forth on the amp while setting the record balance on the deck. Once there is no difference between the stereo and mono mode I figure I got the balance right. On my deck the balance setting is correct  at quater to eleven. Suppose one could set the level higher on the left channel while calibrating but I'm not sure if that's a good idea. A friend of mine has the same problem with his 582, seems like it's inherent with these decks.   Peter   From: jaetee at tampabay.rr.com To: naktalk at naks.com Subject: RE: [naktalk] 582 VU's and recording imbalance Date: Tue, 6 Oct 2009 09:56:09 -0400 Did anyone reply with a fix for this?   My 582 has a similar issue, but not exactly the same... so I will piggy-back on this 582 post.   My 582 has a stronger right channel when I record, and the left VU meter seems more sensitive.     After I've set the bias/level for the particular tape being used, I must adjusting the recording balance just to the right of the 11 o'clock position or I end up with a very imbalanced recording. The VU's look relatively close at that point and playback on other units (as well as the 582) results in pretty close to perfect balance at that point. I'd say its more of a nuisance than a real "problem" but the deck is so nice that I'd really like to have it at 100%.   Any ideas who can fix this and roughly what it would cost?   I'm 97% sure that a tweak of this nature is beyond my abilities..     Thanks in advance for any help.   JT -----Original Message----- From: naktalk-bounces at naks.com [mailto:naktalk-bounces at naks.com] On Behalf Of Tim Skorick Sent: Friday, September 25, 2009 6:04 PM To: Talk about Nakamichi Cassette Decks Subject: Re: [naktalk] 582 Is the right channel actually 10db louder than the left? -Tim On Thu, Sep 24, 2009 at 10:00 AM, Peter Tanner wrote: Hello Ron, Willy and all   A question about my 582.

This causes the grooves to melt, and placing the stylus in those grooves again without waiting causes prematurate wear. You should wait at least an hour to play one side again, but if you can wait more time, that would be preferred.

You guys have extensive record collections that probably cannot be replaced.  Why risk any possible damage to them by using water that definitely has deposits in it that settle inside the record grooves and do damage when a stylus runs over them.  Better still, instead of making your own record cleaning solution, purchase it from legitimate companies that make it specially for records. And Ron, please stop using dehumidifier water for your car batteries.  All battery manufacturers specify distilled water.  Distilled water is very, very cheap and will not damage batteries with any possible contaminants because there aren't any.

I have never made my own cleaning solution, but I intend to. Commercial solutions seem very expensive (I suspect their most expensive ingredient is something called 'markup'). Until that day, I still have some in a Radio Shack [gasp!] can. Washing LPs manually is a very simple procedure. I use very little solution, which I spray directly from the can. I spread with an LP cleaning pad (the same a power pads ladies use on their faces, but 5 times the price) and let it sit for a couple of minutes. I then rinse with my famous distilled water, which I keep in a 1 gallon milk can. This is followed by drying with a soft paper towel (Kay Dry), then buffed with a velvet brush until the LP is dry. The above is OK for visibly dirty records, but not very effective for mold ridden ones. IOW, the record does look much cleaner, but doesn't sound that much better, except for some reduction of surface noise. > > And Ron, please stop using dehumidifier water for your car batteries. > All battery manufacturers specify distilled water. Distilled water is > very, very cheap and will not damage batteries with any possible > contaminants because there aren't any. I've been servicing my own cars ever since I can remember and can't recall a damaged battery, ever (except for one Sears battery, that died after a few months, before I ever had the need to top the electrolyte off). Batteries are designed to perish the day after the warranty expires (or ASAP thereafter). Until that happens, they thrive on water from the dehumidifier -- at least, for me. Don't forget, batteries are semi sealed and require very little replenishment. The same is true for windshield washers. Have been using dehumidifier water for years and years -- never a clogged nozzle.

You can see it on the photo of the service manual, attached to this email. The respective knob is F03. My question is: This knob is it the same part like in the Nakamichi ZX680 ? This deck has the pitch control as well. The knob looks exactly the same as the knob of the 1000 ZXL. My second question is: Can anyone sell me such a knob? Or, can anyone sell me a deck ZX680, it does not need to be functioning, I would only buy it because of this knob. The other parts I would offer as spare parts to this community here.

Apparantly the transport of the tape is not perfect especially in the reverse mode. Sometimes the speed of the tape seems to be goings lower, sometimes it seems to go higher. Sometimes, il is beginning to eat my tape... Could it be a problem with the pinch roller ? or with the direct drive motors ? I have opened the deck and I have seen something strange : The motor that controls the azimuth (with the MAAC) is doing several rotations even when the led of the MAAC is not blinking any more. It does not rotate always but very often (at least one time every 15 second, often more times) during the music : Sometimes it rotates a little, sometimes it rotates a lot. The result is that the treble are not always optimal. It is as if it was moving the head without finding the best azimuth. What I don't understand is that I was believing that every times the MAAC is changing the azimuth, the led should be flashing and that the MAAC was working only when the dragon change of side of the cassette . Yet, from what I see, I must say that my dragon is changing the azimuth of the playback head quite often and without flashing the led Is it normal ? thank you for your help and advices P.O. -------------- next part -------------- An HTML attachment was scrubbed...

Dissolve the crystals in warm distilled water. Pour on LP surface, let it sit for a few minutes, it will gel and dry, penetrating the grooves, and trapping all the dust particles and other grime.

This deck has the pitch control as well.  The knob looks exactly the same as the knob of the 1000 ZXL.  My second question is:  Can anyone sell me such a knob?

First, the tape must go the right way, with accurat lifting an moving pinch rollers. If the pinch roller does not reach the capstan shaft, change the belt from the cam Motor first. If the tape ist going the right way, speed must be allright. If the transport is working correct, the play-head azimuth needs alignment. Better do this by using a Service Manual. after this, the MAAC need to be set, in the middle, and after this re-connect the CN-5. take a look in the SERVICE MANUAL, or ask somebody prof. to do all this work. kind regards Gerhard 2009/10/11 EL GUEDJ Pierre-Olivier > Hello > Recently, I have bought a nakamichi Dragon but I have some problems with > him. > > Apparantly the transport of the tape is not perfect especially in the > reverse mode. > Sometimes the speed of the tape seems to be goings lower, sometimes it > seems to go higher. > Sometimes, il is beginning to eat my tape... > Could it be a problem with the pinch roller ? or with the direct drive > motors ? > > I have opened the deck and I have seen something strange : The motor that > controls the azimuth (with the MAAC) is doing several rotations even when > the led of the MAAC is not blinking any more.

This is normal and should not be cause for concern. The Dragon is the only deck that continually adjusts for high frequency azimuth loss while playing a tape. The eating of tapes might need a good alignment and the motor circuitry might need some electronic components analyzed and serviced. Willy Hermann and ESL are 2 good choices for you in the USA.

Apparantly the transport of the tape is not perfect especially in the reverse mode. Sometimes the speed of the tape seems to be goings lower, sometimes it seems to go higher. Sometimes, il is beginning to eat my tape... Could it be a problem with the pinch roller ? or  with the direct drive motors ? I have opened the deck and I have seen something strange : The motor that controls the azimuth (with the MAAC) is doing several rotations even when the led of the MAAC is not blinking any more. It does not rotate always but very often (at least one time every 15 second, often more times) during the music : Sometimes it rotates a little, sometimes it rotates a lot. The result is that the treble are not always optimal. It is as if it was moving the head without finding the best azimuth. What I don't understand is that I was believing that every times the MAAC is changing the azimuth, the led should be flashing and that the MAAC was working only when the dragon change of side of the cassette . Yet, from what I see, I must say that my dragon is changing the azimuth of the playback head quite often and without flashing the led Is it normal ? thank you for your help and advices P.O. -----Inline Attachment Follows----- ========---------------------------------------------------------=========           Also check out the wiki! http://www.naks.com/wiki ========---------------------------------------------------------=========                         Naktalk at naks.com mailinglist Maintain your account here: http://www.naks.com/mailman/listinfo/naktalk ========---------------------------------------------------------========= -------------- next part -------------- An HTML attachment was scrubbed...

This is normal and should not be cause for concern. The Dragon is the only deck that continually adjusts for high frequency azimuth loss while playing a tape." Unless certain years behave differently, this is not correct. According to Naks own description, the NAAC, will only adjust after initial play, for around 15 seconds (I'd have to look again at the manual or system description to find the exact times). The arrows will flash whenever the phase difference of high frequency material on the split channel head is above a certain value.  It will only readjust when:  switched to record, where it will align with the rec head, or after a prolonged silence of, IIRC, 6-8 seconds.  It only adjusts during the music at the beginning, and after 3 (4?) iterations, (each one successively smaller if NAAC is working correctly) and then stops there, whether the azimuth is absolutely correct, or not, and this is often dependent on enough high frequency content on tape during that time.  If I play the Sounds of Nakamichi tape on my Dragon, the leds never flash, yet I see the L&R levels adjust for 2-3 seconds, as the NAAC adjusts small amounts, then it nails it.  Throw in ANY pre-recorded tape, and watch that baby dance to get it right!  Mine does operate as I described.  I think it would be detrimental to constantly adjust during rec or playback, as playback of a recorded tape would really make a Dragon tape truly only playable on a Dragon, which is not true.  If you want your Dragon to play back all your music without adjusting during it, you only need to record 15-20 seconds of pink noise in the very beginning before the music.  But that is probably more annoying than the NAAC in action and more trouble than it's worth. Sorry, but it really sounds like the Dragon in question may need to be looked at by a pro, or just use it as is. Perry   -------------- next part -------------- An HTML attachment was scrubbed...

Any suggestions GREATLY appreciated!! > Maybe something more straightforward or easier?? > It is not clear to me why you concluded that "it is almost surely a cap issue". At this point of the troubleshooting process, I would concern myself with circuit cause and effect issues. IOW, where in the circuit the problem originates and how. Unless you know something you haven't posted, it is not clear whether the fault is in the analogue or digital sections of the circuit or on what PCB it lies. So, right now, the faulty component type is both unknown and immaterial. It could be a cap, a resistor, a transistor, an IC, or even intermittent ground or power connection or hairline crack in a PCB track (to mention a few). Intermittent faults are always tricky to isolate. I would start by measuring continuity (with power off) of the 'M. Input' path (D305 Cathode on the Main PCB to IC602 pin 34 on the Logic PCB), while gently tapping areas on those two PCBs in the vicinity of these components and around FC-8 on the main PCB and CN608 on the logic PCB. I would also gently move and pull on the connecting cable itself. Once the connection is found to be solid, I would hang a logic probe on IC602 pin 34, run the deck and see if there is a spike on the 'M. Input' line just before the deck misbehaves. If so, the fault is on the main PCB. To ascertain, I would repeat with the probe on D305 cathode. (Simply measuring DC voltage is no good, as short spikes are sure to be missed. A 'scope may be used, but is difficult to set up properly). Results of the above will tell me how to proceed. If the fault is on the analog side (main PCB), a 'scope will be very useful. If the problem is with IC602, that would be bad news, as the IC is all but unobtainable. Good luck, -- Ron -------------- next part -------------- An HTML attachment was scrubbed...

You could look at the decks that have playback azimuth control (auto or manual) and get maybe a couple of percent better performance (especially in the high end) assuming your deck is set up correctly and the tapes are not bad. Is it worth the money? Decks such as the dragon (auto) or cassette deck 1 (manual) are not cheap. The BX-300 is common enough that parts decks can be had for a good price. I'd stick with the BX-300 and spend money on service if needed, but that depends on how important it is to get the last little tiny bit out of your cassette find.

Two of them serviced. One by Willy. They sound phenomenal! I have observed the continuous azimuth adjustment in all 4 decks after the initial lamp flashing and this goes on throughout the tapes run. The sway of azimuth is a very short range but it does not stay still. This amount of the azimuth sway does not cause extensive movement of the playback head, but just some fine tuning as the deck plays. If the sway is of much larger amplitude, then I agree there is an issue that needs to be attended. Please open your deck's top cover and pay close attention to the azimuth pointer. You will see this occur.

But what at a high level should I be looking for in terms of a "tune-up" or who should I turn to to do this for me. The only problem is that it takes a little time to "warm" up before it starts to play. The deck will play for a few seconds but then stop. It does this a few times but then works fine.

In the first 15 seconds it will respond 'full bandwidth', sometimes moving the head a great deal. After the initial lock in time, the weighting reduces the range of the azimuth adjustment. This allows the natural phase integrity found in stereo recordings to be maintained. If a tape has very little high frequency information, the initial lock in period is extended. Note that the azimuth circuit also knows that PAUSE is different from STOP, so there is no initial search period when going from pause to play. tom brucker -----Original Message----- From: naktalk-bounces at naks.com [mailto:naktalk-bounces at naks.com]On Behalf Of shanti ramachandran Sent: Tuesday, October 13, 2009 8:15 AM To: Talk about Nakamichi Cassette Decks Subject: Re: [naktalk] Re: Problem with a Nakamichi Dragon Perry, I have four Dragons at home. Two of them serviced. One by Willy. They sound phenomenal! I have observed the continuous azimuth adjustment in all 4 decks after the initial lamp flashing and this goes on throughout the tapes run. The sway of azimuth is a very short range but it does not stay still. This amount of the azimuth sway does not cause extensive movement of the playback head, but just some fine tuning as the deck plays. If the sway is of much larger amplitude, then I agree there is an issue that needs to be attended. Please open your deck's top cover and pay close attention to the azimuth pointer. You will see this occur.

This is normal and should not be cause for concern. The Dragon is the only deck that continually adjusts for high frequency azimuth loss while playing a tape." Unless certain years behave differently, this is not correct. According to Naks own description, the NAAC, will only adjust after initial play, for around 15 seconds (I'd have to look again at the manual or system description to find the exact times). The arrows will flash whenever the phase difference of high frequency material on the split channel head is above a certain value. It will only readjust when: switched to record, where it will align with the rec head, or after a prolonged silence of, IIRC, 6-8 seconds. It only adjusts during the music at the beginning, and after 3 (4?) iterations, (each one successively smaller if NAAC is working correctly) and then stops there, whether the azimuth is absolutely correct, or not, and this is often dependent on enough high frequency content on tape during that time. If I play the Sounds of Nakamichi tape on my Dragon, the leds never flash, yet I see the L&R levels adjust for 2-3 seconds, as the NAAC adjusts small amounts, then it nails it. Throw in ANY pre-recorded tape, and watch that baby dance to get it right! Mine does operate as I described. I think it would be detrimental to constantly adjust during rec or playback, as playback of a recorded tape would really make a Dragon tape truly only playable on a Dragon, which is not true. If you want your Dragon to play back all your music without adjusting during it, you only need to record 15-20 seconds of pink noise in the very beginning before the music. But that is probably more annoying than the NAAC in action and more trouble than it's worth. Sorry, but it really sounds like the Dragon in question may need to be looked at by a pro, or just use it as is.

It is a fairly low serial number deck, so more likely to have aged cap issues. 2. In my experience, problems that occur once per power up, or once until something is set, are usually analog in nature, and normally caused by something in the circuit that is barely working correct, but with some other condition, is within tolerance. A cap fits that descrition well, whereas a resistor or transistor, the vast majority of the time, fail absolutely. 3. Lets face it, lots of caps on Naks from this era have issues. I'll play with the odds first. Your troubleshooting advice is spot on, and along the lines of what I was looking for, thanks. If I can' find any cold junction, bad wire, or open/short issues, the next easiest thing is to verify supply voltages, and if good, then test the caps with my ESR meter, and replace the questionable ones. I have a fairly good set of test and repair instruments. The problem is that it is not exactly intermittent. It is unpredictable, but almost always happens during each session, and from what I can recall now, happens only once each power up, or rarely twice. There have been days when it hasn't happened at all, usually if I hadn't used the deck for a while. I still have some conditional testing to do, to help narrow down the possibilities. It may well not be a cap because I went though years of Naktalk archives and could not find any previous posts that were similar. So not remotely a common problem, and with as many RX-505s out there as there are (or decks with a similar blank skip circuit), I'd have thought someone would have run across it at least once before. I've never had any issues with the flip position pot and that has come up a number of times n the past. Luckily I have another perfectly working, late serial number RX-505 to compare it too. I really was just looking for some validation of my logic. (I mean, it MIGHT have nothing at all to do with the blank skip circuit, but it's not like a lot of things trigger FF. -------------- next part -------------- An HTML attachment was scrubbed...

This is normal and should not be cause for concern. The Dragon is the only deck that continually adjusts for high frequency azimuth loss while playing a tape." Unless certain years behave differently, this is not correct. According to Naks own description, the NAAC, will only adjust after initial play, for around 15 seconds (I'd have to look again at the manual or system description to find the exact times). The arrows will flash whenever the phase difference of high frequency material on the split channel head is above a certain value. It will only readjust when:  switched to record, where it will align with the rec head, or after a prolonged silence of, IIRC, 6-8 seconds. It only adjusts during the music at the beginning, and after 3 (4?) iterations, (each one successively smaller if NAAC is working correctly) and then stops there, whether the azimuth is absolutely correct, or not, and this is often dependent on enough high frequency content on tape during that time. If I play the Sounds of Nakamichi tape on my Dragon, the leds never flash, yet I see the L&R levels adjust for 2-3 seconds, as the NAAC adjusts small amounts! , then it nails it. Throw in ANY pre-recorded tape, and watch that baby dance to get it right! Mine does operate as I described. I think it would be detrimental to constantly adjust during rec or playback, as playback of a recorded tape would really make a Dragon tape truly only playable on a Dragon, which is not true. If you want your Dragon to play back all your music without adjusting during it, you only need to record 15-20 seconds of pink noise in the very beginning before the music. But that is probably more annoying than the NAAC in action and more trouble than it's worth. Sorry, but it really sounds like the Dragon in question may need to be looked at by a pro, or just use it as is. Perry  -------------- next part -------------- An HTML attachment was scrubbed...

Any suggestions GREATLY appreciated!! > Maybe something more straightforward or easier?? > It is not clear to me why you concluded that "it is almost surely a cap issue". At this point of the troubleshooting process, I would concern myself with circuit cause and effect issues. IOW, where in the circuit the problem originates and how. Unless you know something you haven't posted, it is not clear whether the fault is in the analogue or digital sections of the circuit or on what PCB it lies. So, right now, the faulty component type is both unknown and immaterial. It could be a cap, a resistor, a transistor, an IC, or even intermittent ground or power connection or hairline crack in a PCB track (to mention a few). Intermittent faults are always tricky to isolate. I would start by measuring continuity (with power off) of the 'M. Input' path (D305 Cathode on the Main PCB to IC602 pin 34 on the Logic PCB), while gently tapping areas on those two PCBs in the vicinity of these components and around FC-8 on the main PCB and CN608 on the logic PCB. I would also gently move and pull on the connecting cable itself. Once the connection is found to be solid, I would hang a logic probe on IC602 pin 34, run the deck and see if there is a spike on the 'M. Input' line just before the deck misbehaves. If so, the fault is on the main PCB. To ascertain, I would repeat with the probe on D305 cathode. (Simply measuring DC voltage is no good, as short spikes are sure to be missed. A 'scope may be used, but is difficult to set up properly). Results of the above will tell me how to proceed. If the fault is on the analog side (main PCB), a 'scope will be very useful. If the problem is with IC602, that would be bad news, as the IC is all but unobtainable. Good luck, -- Ron -------------- next part -------------- An HTML attachment was scrubbed...

I was going off of Naks literature and my observations of perhaps 10 tapes over the last 2 weeks, so I am by no means any kind of NAAC authority! In fact, last night, while listening to an otherwise fine recording of Classical Gas on a 1986 XLII-S, I occasionally heard a clicking noise that I couldn't identify, and I thought it was on the recording as it occurred in the same spots. I turned the volume down and lo & behold, I could hear the NAAC motor and the clicking was the end of travel, and there was no arrow flashing when it occurred. I turned the tape over and played it in reverse and no noise/action. I realize now that I had been playing my favorite tapes, all recorded on my RX-505, or Nak reference tapes, or Windham Hill prerecorded tapes, and the Dragon simply hadn't needed to make any adjustments once set! Thank you all for setting the record straight, I hate when I open mouth and insert foot, but would rather do it amongst friends than advasaries! On a side note, is there any chance of damage to the NAAC mechanism from end of travel clicking? Thanks!

Lots of times this hitting the end ( which causes clicking) damages the Azimuth unit. Sometimes the moving roller unit over the gear gets stuck at one end. Since many donot hear these clicking sound due to the music paying loud on speakers, it looks like enough damage is done already. Avoid playing tapes causing such azimuth tracking to drift off to the edge kannan --- On Fri, 10/16/09, Luis Peromarta Regert wrote: > From: Luis Peromarta Regert > Subject: Re: [naktalk] NAAC problems with Dragon > To: perry.nak at comcast.net, "Talk about Nakamichi Cassette Decks" > Date: Friday, October 16, 2009, 3:12 PM > I don't think so, unless it clicks > for hours and hours. > r > El 16/10/2009, a las 17:58, perry.nak at comcast.net > escribió: > > > On a side note, is there any chance of damage to the > NAAC mechanism from end of travel clicking? > > > ========---------------------------------------------------------========= >          Also check out the > wiki! http://www.naks.com/wiki > ========---------------------------------------------------------========= >                 >        Naktalk at naks.com > mailinglist > Maintain your account here: http://www.naks.com/mailman/listinfo/naktalk > ========---------------------------------------------------------========= > From timpamsepper at cox.net Sat Oct 17 02:01:29 2009 From: timpamsepper at cox.net (Tim and Pam Sepper) Date: Fri, 16 Oct 2009 17:01:29 -0700 Subject: [naktalk] RE: Hey Willy, read this!!

Since many donot hear these clicking sound due to the music paying loud on speakers, it looks like enough damage is done already.

Those Nak in-line filters (not mentioned by you but found on ebay) are single pole. When using Dolby, especially C, the subsonic energy can limit the Dolby compression, reducing the noise reduction effect. I would guess without analyzing the circuits, that the Dragon's filter is optimum for the Dragon, while the 410 is probably a 3 pole filter best used with old turntables. The SR4 will be 2 pole at least. Remember, the price one pays for filtering is phase shift up into the bass region. The best filter is no filter, so you might investigate some of the ultra low rumble turntables, such as the Linn Sondek. If you are taping 78s, be sur to use a mono cartridge to eliminate rumble. tom brucker -----Original Message----- From: naktalk-bounces at naks.com [mailto:naktalk-bounces at naks.com]On Behalf Of Mark Exstedt Sent: Monday, October 19, 2009 9:46 PM To: naktalk at naks.com Subject: FW: [naktalk] The Nakamichi Subsonic Filter Well it's been five days and no reply (sob).

Given the price of simply buying a 682ZX it wouldn't be close to worth it. It is WAY more than just adding a switch. The reason Nak could offer the 681ZX for substantially less money is the lack of a second set of play electronics as well as the extra pair of Dolby chips and all their associated components.

From my experience selling these decks, the monitoring versions sold about 5:1 over the non-monitoring ones. I think they eventually figured this out, and stopped offering the non-monitoring 3-head decks around the era of the LX-5.

My experience selling all these decks was the same as yours although the $100 difference seemed larger at the time than it does now. For those who don't know the reason for going to three heads - the head gap should be somewhat different for recording and playback. In a two head machine, the gap width is built to split the difference. Both the frequency response and linearity of record to playback is better on a properly designed and built three head deck. That said, there were MANY three head decks produced by other manufacturers which didn't hold a candle to the Nakamichi two head decks.

The motor went bad after couple of months and Willy was very gracious in replacing the motor. Now to the sound, I have in my collection over 30 Nakamichis, basically everything except the ZXL line, and almost all calibrated. In very subjective tests 3014A sounds best to my ears, closely followed by Dragon, 680-ZX and ZX-9. I listen to music that has lots of vocals, both male and female. My advice is that if you are a Nakamichi fan and get an opportunity to buy a Tandberg 3014A, go for it. Aamir Willy Hermann wrote: > I have made that comparison many times. I used to sell both.

He felt the Tandberg recorded more accurately (measured) but that the Dragon played back more accurately. So, he recorded with the Tandberg and played back with the Dragon. I seem to recall he felt the Tandberg was better built, too. A few years ago, Tandberg were still building the 3014's to special order.

To achieve these goals, the circuit usually contains highly specific parts, making a successful repair by the non initiated highly unlikely. This, in turn, can be due to requirements of matched and/or specially selected transistors or capacitors, or the need for specialized test equipment.

To: mark8559 at hotmail.com; naktalk at naks.com Subject: The Nakamichi Subsonic Filter Date: Sat, 24 Oct 2009 13:03:34 -0400 From: johngipps at aol.com Hi Mark Tom is quite correct - Nakamichi incorporated subsonic filters in many of their cassette decks because the presence of subsonic information in a signal that is being recorded can greatly interfere with the operation of Dolby noise reduction systems. This was really only a problem when recording from a turntable. A turntable at any quality level can output subsonic information due to record warp and eccentricity (the hole not accurately in the centre), and from mechanical disturbances to the turntable from it's environment (for instance, someone walking heavily near the turntable in a house with a wooden floor). As a result of this problem, reported by a significant number of my customers back in the days when the turntable was the most common source for recording, we used to routinely fit high pass filters to Nakamichi decks that we sold. In particular, the 480 series used to get this treatment often - they were very common models, and didn't have a subsonic filter. We found that a first order high pass filter with a pole at about 20Hz had enough attenuation over the range of frequencies causing the problem - so the filter was simply one capacitor in series with the input of each channel, and this interacted with the cassette deck input impedance to produce the required pole. While a higher order filter might have been desirable, we didn't want to overly interfere with the decks, and the simple solution worked well. The subsonic filter in both the 410 preamp and the SR-4 receiver is dedicated to the phono input - it isn't available for the other inputs. The arrangement in both is unusual, in that the record out of both is subject to the subsonic filter. Most preamps and amplifiers do not filter record out signals. Clearly, Nakamichi decided to do this because of their involvement with cassette decks using Dolby NR. So with a 410 or an SR-4, you don't need a subsonic filter in your cassette deck. It's interesting to note that the subsonic filters in the 410 preamp and the Dragon have the same reasonably uncommon topology, and yet the 410 design is much older than the Dragon design. Maybe some Nakamichi designers were around for a long time, and oversaw different generations of their products. If I was making a recording from a turntable with your system Mark, I would use either the Dragon subsonic filter, or the one in the preamp (410 or SR-4), but not both at the same time. While there's no harm in using the Dragon subsonic filter for other input devices (eg CD), there's probably no need to. Hope this answers some of your questions.

To: mark8559 at hotmail.com; naktalk at naks.com Subject: The Nakamichi Subsonic Filter Date: Sat, 24 Oct 2009 13:03:34 -0400 From: johngipps at aol.com Hi Mark Tom is quite correct - Nakamichi incorporated subsonic filters in many of their cassette decks because the presence of subsonic information in a signal that is being recorded can greatly interfere with the operation of Dolby noise reduction systems. This was really only a problem when recording from a turntable. A turntable at any quality level can output subsonic information due to record warp and eccentricity (the hole not accurately in the centre), and from mechanical disturbances to the turntable from it's environment (for instance, someone walking heavily near the turntable in a house with a wooden floor). As a result of this problem, reported by a significant number of my customers back in the days when the turntable was the most common source for recording, we used to routinely fit high pass filters to Nakamichi decks that we sold. In particular, the 480 series used to get this treatment often - they were very common models, and didn't have a subsonic filter. We found that a first order high pass filter with a pole at about 20Hz had enough attenuation over the range of frequencies causing the problem - so the filter was simply one capacitor in series with the input of each channel, and this interacted with the cassette deck input impedance to produce the required pole.

Actually, I checked 4 SM: those of ZX7, BX-300E, RX505E and finally CR7E. The bias oscillator is detailed for either ZX7 or CR7E, but is neither for BX-300E nor RX505E. It seems strange (at least to me) that sometimes in 1982 the Bias Osc. was detailed for ZX7, then, let's say around 1985, was no longer detailed at the time of BX-300/RX series, and again in 1986 and later, was detailed again for the CR7! Now, having problems with the bias oscillator of my ZX7, your explanation brings to me another question, particularly after having red some notes on Scott's site about "orange caps desease": After this reading, I got the feeling that a "simple swap" of the 3 orange caps (and may be of the 2 related transistors, 2SC945 for ZX7) could restore the erase /record function? am I wrong? It seems that this Bias Osc. failure is particularly true for the ZX7/9/ 480/482 decks: is it true? Again, I do apologize for asking boring questions for most of you, but this is due to my lack of knowledge in electronics...

Or, it could be the coil and/or transistors and/or the PCB itself, etc., etc.,. But, yes, it should be a simple matter to tear into the module and test all the above.

Best deal was the £2 for a pair of Spendor BC1's and £20 for a pair of Lowther Acoustas with PM7's. Saddest deal was £5 for estimated 2000 cassettes, all in plastic bags and dumped amongst the crap. Many were damp or cracked. They were all colour coded and referenced, the own recordings with elaborate sleeve notes, extracts from listings in the Radio Times over a period of 20 years - a wonderful collection. I salvaged 100 just on sacred music, 300 or so on original classical, top price recordings from Decca etc and several hundred blank tapes including a dozen TDK metals.

With the Metalized the conductor is a metal film that is directly on the dielectric film so they are more compact. If you are replacing audio coupling capacitors in a Nak will be hard because a PP will be approx 100-times larger than the same value electrolytic. I would replace a stock electrolytic with a modern High Frequency, Low ESR electrolytic and then bypass it with a .01uf-.1uf PP under the circuit board. If you are replacing the notorious "Orange Caps" then the PP should be just slightly bigger.

Message-ID: <32470900.4726431256817811120.JavaMail.root@sz0163a.westchester.pa.mail.comcast.net> Haven't seen this anywhere..sooo.. I had calibrated both Type I and II tapes, just fine on the A801, and then recorded a recent NOS sealed album, (turns out, not such a great album,) on an '85 TYPE 2 XLII-S, pre-owned in nice condition. When I first started the recording, it sounded good, maybe the sound seemed a bit flatter sounding than I remembered it should have been, and I swore the difference in highs was worse near the end of the tape. So I decided to re-calibrate it after this two album sides. And surprisingly it was pretty off! (indicators for level and bias were not near the cal point), and as a matter of fact...I couldn't get it to calibrate...WTF? Something wrong with this tape? So I decide to calibrate an MA-R on it. And it won't, either. Not even close!! Can't get enough bias to get anywhere near the cal point. I put the tape I just recorded back in, and checked the calibrating and it is still off, way off. Dang,..don't tell me the 15kHZ oscillator was worn/weak itself. I put both tapes in the B215 I've been working on, and they calibrate fine. In fact, (not surprisingly) the MA-R does a great job recording. Not the tapes. Crap!, my recent to me Dragon must have a problem...I mean, all I did was record a tape that I have no idea what the history was, but LOOKS fine on it.....but that 15kHz signal sure looks low on the meters....Bottom line, was I figured the only thing to try was to clean the heads again to get a 15kHZ signal strong enough on the tape to cal the tape!! And that's all it was. Both tapes calibrated easily, and the 15kHz signal was at -20db on the meters. Is the Dragon (and other similar Naks with 15kHz tones) THAT sensitive to buildup? I bet I've only played 5 tapes on it since I cleaned and demaged it last. I've got no auto cal on my RX-505s and the Yamaha's ORBIT and Revox auto cal sure don't seem this sensitive. OR is the Dragon a particular PITA because of the NAAC. If you don't have the azimuth close (from previous content), then as you switch between 400 Hz and 15kHz, it can only try to align to a weak 15kHz signal, and if it gets too off, you'll NEVER see 15kHz... The manual makes reference to a "rough" calibration if you can't get it in during manual cal. I tried that and it didn't work either, until I cleaned the heads, which showed nothing on the swab, btw. I've marked this tape "suspect" until I try it on other decks. With the MA-R, the Dragon then recorded near perfect, as you'd expect. I may start re-thinking my stance on "quality used tapes are fine"..I've got a bunch of new welded SA-90s (Bought 2 cases, before I realized what crappy shells they had) ....I'm going to see what the Dragon does with them, as well. -------------- next part -------------- An HTML attachment was scrubbed...

I recently had a similar problem with a transport and found that the potting resin on the record head (on the play head side so it was nearly impossible to see) had gotten chipped somehow and was gouging the tape causing the oxide to flake off and foul the tape path in less than one half of a side of tape. Odd problem and the only one I'v ever seen but it's the only explanation I can think of for your problem. I was able to lap the record head and polish below the chip to make the tape surface smooth again. That solved the problem completely. Let us know of you find such a problem as it may mean the potting resin is beginning to deteriorate - wouldn't that be a drag!!

I have an old BX-125 that I ran all the time for a number of years. The original capstan motor died on it, and when I had it replaced, it died about six months later. I took it back to the repair guy, and he said that this was normal, that once the original motor dies, the replacements are always inferior, and are prone to break faster."

If you Dragon does playback anyway, you can start with the record head alignment, first. Disconnect CN-5 on the main PCB , that way the NAAC is not working. If you have a test cassette or a very good recorded music cassette you check the playback, without Dolby and on 120 sec. for Tape type Nr.1, That way you have the most high frequency on the music. Align the playback azimuth to the best high frequency on this tape. Azimuth alignment Rec. head: While recording the 15kHz Testtone, aighn the Azimuth with a screwdriver. TAPE SHOULD NOT STOPP AT THIS TIME! MAKE SHURE TO USE ONLY THE RIGHT SCREWS! for azimuth Set Bias , and Level from the Dragon calibration first to showing maximum Level, Finding maximum reading with setting the record head azimuth, same time. After this, bias and Level back to 0 db again. 0db on the meter will show you 20 below on the 20 kHz test tone. If the Dragon is recording perfect again you did win! If not, it can be because of a week bias oscillator or a week recording electronic. Some times the electronic works better if you leave it working for a while. If you Dragon playback heads did get alignment , you must look to the black box of the NAAC. When you press play in back or forward , and Playback in Rew. WITH CASSETTE DOOR OPEN. The white point on this black box should be in the middle position. If not you have two various resistors on the main P.C.P to set the middle again. Playback Azimuth Reverence Rev. VR823, for Fwd. playback VR 824. I have done this, and the trac alignment, it is a step more, to my new Dragon , it works perfect again.

This can happens when the control motor is stuck in between positions. The thing to do is to press Stop and ascertain the control motor has rotated the cam to the Stop position. If not, helping the motor with a finger (not easy to get in there) or a small stick may help it to get started. -- Ron Luis Peromarta Regert wrote: > Hi Gurus. > > Is this fixable?

Yes, I am sure the response problem is due to head wear and yes shorting the resisters you identified does indeed give an increase of around 3 - 4 dB at 20kHz. I have also been able to achieve an equal and flat response at 10kHz now by slightly increasing the values of R109 (209) which peaks up the 70uS response curve very nicely. It is a shallow victory though, as obviously the head is worn to the point of considerably increased gap width. I may consider lapping, but not sure if it is worth it. Are NOS Nak heads available anywhere? By the way, I approached servicemanuals.net about my missing pages in the manual I downloaded, and within 24 hours I had the missing pages available for download. Regards David Upon examining the head, I can see what I think looks like a flatter than the preferred profile but thought that the left and right channels would deteriorate at much the same rate in terms of gap wear. This may seem logical but is never true. One channel (usually the outside one) deteriorates faster than the other and your measurements are classic for worn play head. The playback frequency adjustments will gain you a maximum at 4dB at 20kHz and are intended for tailoring the deck to slight head variations. If you want to verify that, find R111(211) and R112(212) on either side of L101 and L201. Shorting R112 should give you 2dB and R212 an additional 2dB at 20kHz. If you don't have a replacement head you can probably get it lapped. Nak heads are generally deep enough to lap at least once.

Thus far it has had the usual stuck pinch pivot arm fixed, capstan flywheels cleaned and relubricated, all new rubber including pinch rollers, certain AC coupling caps and all PolyProps changed in preparation for full electrical alignment. However, I have a slight problem. Before and after the cap changes, I logged the performance in both record and playback in terms of levels and frequency response, and noted a 5dB drop off at 5K and up to 7dB at around 18K on the right channel only, during play back. Play and Record heads have been thoroughly cleaned and de-magged, had height and azimuth carefully adjusted using (20 dB down) test tones recorded on my pristine ZX-9, (which as already discussed, is not as good as genuine test tapes, but all I have at this stage). This frequency drop-off is I believe associated with the head as I can swap the head channels and transfer the frequency roll off to the other (left channel). It is also measurable with a CRO very early in the head amp circuit. Upon examining the head, I can see what I think looks like a flatter than the preferred profile but thought that the left and right channels would deteriorate at much the same rate in terms of gap wear. Anyway, looking at my ZX-9 service manual, I note that there are a couple of resistors associated with both the Head Amp and Dolby Circuits that are "select on test" based on initial frequency response measurements in addition to some resistors that can be shorted out in order to improve the equalisation response. Unfortunately, the 482 Service Manual I purchased form servicemanuals.net is missing pages 35, 36 and 37 or section 7.2 in the PDF scan, which is where this detail is. Can anybody help with either the R numbers and suggested values, or better still a scan of the relevant pages form the 482 service manual? Any help would be very much appreciated.

The rationale is that some azimuth error is caused by movement of the shell during play. This, is turn, is caused by force transmitted to the shell by the moving tape. By adjusting for zero error at the middle of the tape, worst case error is supposedly halved. OTOH, seeing that force exerted by the tape is infinitesimally small and even the chintziest of shells is seated fairly rigid, this shouldn't be taken too seriously. Personally, I adjust recording azimuth anywhere except very close to tape ends and never noticed HF response variations along a cassette. BTW, purists also adjust azimuth separately for each side. The idea here is that shells are not perfectly flat and, therefore, each side will have it's own error, independent of the other side. This make a lot of sense. When I still owned a 582, I noticed that adjustments for each side were invariably different, though not by much. -- Ron Graham A Nelson wrote: > I recall hearing it said that, when setting the azimuth prior to recording > onto a tape, the process should not be done at the start of the tape but > some distance down the reel.

Assuming I want the ZX7 as good as I can get it, what do I now do? As this is playing into the Nak, I note that the left hand channel is one segment down on the right with level knobs set at 12 o clock. Do I adjust the record head while listening to the playback of the white noise till they are the same? If I do this, I presume the white noise tape I make can then be used to set up the BX or do I make a tape with test tones now I know the ZX7 is as good as I can reasonably get it. If I presume I could also use the pre-recorded 800hz signal from my Ampex r-to-r test tape instead of white noise. It has 800,1,000,8,000,10,000 and 13,000 hz frequencies Thanks for putting up this if I am asking the obvious.

The azimuth adjust on the ZX-7 is for the record head and aligns its azimuth with its own play head. Once done, you can use that tape to adjust the play head azimuth on your BX-300 by looking for maximum play output. At that point you will have matched the play azimuth on the two decks. If it was wrong on the ZX-7 you will have duplicated that error on the BX-300. Presuming it's all correct, you can set the record head azimuth on the BX-300 for maximum high frequency response. The right way to do it is with a signal generator but you can come very close by using white noise (like a de-tuned FM radio) and adjusting the record head azimuth as you listen to the playback. The biggest danger with any of the home brew test tapes out there is that they are dependent on the set up of the recording deck. Also, as Ron just detailed, the height adjust tape cannot be duplicated on a regular cassette deck. I might also add, the 3kHz wow/speed tape is very dependent on the recording machine. I'm sure Nakamichi made those tapes on a modified open reel deck in order to obtain wow and flutter low enough to be used as a measurement standard. BTW - I recall that there was someone on NakTalk who was working with a Studer open reel transport and was coming close to the ability to reproduce these tapes accurately. Still out there?

Some tapes are worse than others in my experience. I set all the parameters for each and every tape/side. I noticed differences in quality tapes from the same batch. The best success I've had with decks with no PB azimuth adjusters (aside from the white dials) is to just stick with tapes recorded on itself. -----Original Message----- From: naktalk-bounces at naks.com [mailto:naktalk-bounces at naks.com]On Behalf Of Ron Sent: Tuesday, September 01, 2009 9:27 AM To: grahamanelson at googlemail.com; Talk about Nakamichi Cassette Decks Subject: Re: [naktalk] Setting Azimuth question For the purist, yes. The rationale is that some azimuth error is caused by movement of the shell during play. This, is turn, is caused by force transmitted to the shell by the moving tape. By adjusting for zero error at the middle of the tape, worst case error is supposedly halved. OTOH, seeing that force exerted by the tape is infinitesimally small and even the chintziest of shells is seated fairly rigid, this shouldn't be taken too seriously. Personally, I adjust recording azimuth anywhere except very close to tape ends and never noticed HF response variations along a cassette. BTW, purists also adjust azimuth separately for each side. The idea here is that shells are not perfectly flat and, therefore, each side will have it's own error, independent of the other side. This make a lot of sense. When I still owned a 582, I noticed that adjustments for each side were invariably different, though not by much. -- Ron Graham A Nelson wrote: > I recall hearing it said that, when setting the azimuth prior to recording > onto a tape, the process should not be done at the start of the tape but > some distance down the reel.

Some of the higher end carts try to compensate for this by winding the coils with different impedances but I still would never trust the output level from a record to be identical for both channels. ----- Original Message ----- From: John Chapman To: Talk about Nakamichi Cassette Decks Sent: Tuesday, September 01, 2009 8:24 AM Subject: Re: [naktalk] Test tapes Hi Willy, and Ron before, and others I have a test LP record with white noise, recorded, I quote, "nominally -15db ref 1.12 x 10-3cm peak amplitude". Assuming I want the ZX7 as good as I can get it, what do I now do? As this is playing into the Nak, I note that the left hand channel is one segment down on the right with level knobs set at 12 o clock. Do I adjust the record head while listening to the playback of the white noise till they are the same? If I do this, I presume the white noise tape I make can then be used to set up the BX or do I make a tape with test tones now I know the ZX7 is as good as I can reasonably get it. If I presume I could also use the pre-recorded 800hz signal from my Ampex r-to-r test tape instead of white noise. It has 800,1,000,8,000,10,000 and 13,000 hz frequencies Thanks for putting up this if I am asking the obvious.

Maybe a verbal description of the problem would have been clearer that the video. It's possible the control cam is not at the correct position. This can happens when the control motor is stuck in between positions. The thing to do is to press Stop and ascertain the control motor has rotated the cam to the Stop position. If not, helping the motor with a finger (not easy to get in there) or a small stick may help it to get started. -- Ron Luis Peromarta Regert wrote: Hi Gurus. Is this fixable?

It is not that simple Electronically you can use the signal in two different circuts each doing its own part without affecting the other part - that is what happens in NAAC and this does not affect the quality of reproduction in anyway Probably somebody else can help you with arguments to prove it. - This is my observation basing on my own listening to variuos Nakamichi cassette recorders in different conditions. NAAc infact helps to get the correct phase of the original signal by corrrecting head azimuth.

Maybe a verbal description of the problem would have been clearer that the video. It's possible the control cam is not at the correct position. This can happens when the control motor is stuck in between positions. The thing to do is to press Stop and ascertain the control motor has rotated the cam to the Stop position. If not, helping the motor with a finger (not easy to get in there) or a small stick may help it to get started. -- Ron Luis Peromarta Regert wrote: Hi Gurus. Is this fixable?

The Dragon head's right channel is split into two portions. This, and the left channel which is a normal head, is fed into discrete op-amp based amplifiers which boost the signals. The two right channel signals are then tapped off to the NAAC circuit while simultaneously being fed to the main playback circuit. Because the deck is op-amp based, signal loss is practically negligible. When I mean head in this case, it is really the assembly within the head itself. Thus by comparing the phase from both halves, the system can accurately adjust the best possible azimuth for the given tape.

First, the Dragon uses a different output of the head for NACC. Second, if it didn't, the head output would be buffered (amplified), then fed to both monitoring (listening) and NACC circuits, without interaction between the two. Each will get 100% of the signal it needs, unbeknown to the head. This is simple to design. In general, a signal source would not be 'deprived' of signal when used to drive another circuit or two or three or many, provided the whole thing is designed properly. Think of it as a candle not being deprived of it's fire when used to light another candle, or two or three or many. -- Ron jayson levitz wrote: > Hi Kannan. > > I believe I am right about this, but correct me if I am wrong.

Look for Service Information OOD-M-0198. Be aware that it is intended for techs, not users. It requires some knowledge and experience with electronic device construction, not to mention, soldering on PCBs. Associated circuits should be calibrated after completion, as the mod entails replacement of REC EQ components. The gear drive is not available off the shelf anywhere, except maybe from ESL. Your best bet is a parts deck. Replacing the reel motor is best done by an experienced tech. I am not sure the benefit (not having to simply replace a cheap rubber tire) is worth the trouble/expense, but YMMV. Remember that the deck should get routine service about every couple of years, anyway. -- Ron Robert Kovacs wrote: > I am wondering if anyone has information about the mod procedure?

The drift is 0.6 % per my T-100. This drift happens over some time. The 0.6% slow down is after about 90 minutes of tape play. If you stop the tape and let it rest a bit (while the deck is still on), the speed creeps up again. I think it is some heat issue but not sure. Is it possible some components on the D/D motor control pcb is bad? Orange caps? None of my other Nak decks show this behavior. I did hear this problem is not uncommon and is sort of a bug with some models. It can be corrected. Any idea what this issue may be?

Willy fixed mine and a 660zx as well. I know Willy sent the procedure to the list some time ago but not sure when. Note that if you wreck them trying to fix them the only replacement is another deck's meters display - the entire display since it is all one big part!

As i do not dispose of the original mails I am referring herewith to the archive entry: http://www.naks.com/mailman/private/naktalk/2009-August/044600.html I am no native English speaker but I will try to make myself understood: I am using the original Nakamichi test tapes to align a ZX-9 with the Nakamichi T100. I am using the special 1KHz tape (TA Track Alignment) first to adjust the track. My test cassettes which I am selling on Ebay now have 400Hz to set the level and 15KHz to set the Azimuth. Both frequencies are on this tape to find the peak on both channels. It makes sense to adjust every cassette deck identically and it makes sense that the basis of this alignment process are the original Nakamichi test tapes. But these are already very old and rare and in the future it might be necessary to produce new ones on the basis of these original ones. For this reason I am also working on reproducing the unique 1KHz tape from Nakamichi with the number DA09007A. If anybody can help how to record such a tape it would be welcome. Maybe it is possible to use the playback heads of a dragon cassette deck for recording. So far, if the electronic of any cassette deck is working properly, you can allign your playback head with this 400Hz level 0db and 15 KHz for Azimuth. In 1979, Nakamichi gave only 400Hz tapes to every new Nakamichi 1000 cassette deck, as they said, for recurring periodical examination of the adjustment of the heads. This is the original text for their cassette: " This factory certified cassette tape was used for final calibration and testing of your Nakamichi cassette deck. Please use this cassette as a reference tape for periodic verification of your cassette deck's performance. Nakamichi Research Inc." My alignment cassette which I am selling on Ebay has the same 400Hz plus 15 KHz for aligning the playback Azimuth on the same track, made with the original Nakamichi alignment tapes. Looking forward to any feedback. Thank you.

After all, there were (probably still are) other cassette manufacturers who could produce decks with better w/f than Nakamichi. Correct me if I'm wrong but I don't think any Naks bettered 0.023% WRMS, which was the factory spec for Pioneer's CT-830S and CT-730S decks.

Graham From: naktalk-bounces at naks.com [mailto:naktalk-bounces at naks.com] On Behalf Of Willy Hermann Sent: Sunday, August 30, 2009 7:01 PM To: Talk about Nakamichi Cassette Decks Subject: Re: [naktalk] Test tapes All depends on whether your ZX-7 has been properly adjusted. The azimuth adjust on the ZX-7 is for the record head and aligns its azimuth with its own play head. Once done, you can use that tape to adjust the play head azimuth on your BX-300 by looking for maximum play output. At that point you will have matched the play azimuth on the two decks. If it was wrong on the ZX-7 you will have duplicated that error on the BX-300. Presuming it's all correct, you can set the record head azimuth on the BX-300 for maximum high frequency response. The right way to do it is with a signal generator but you can come very close by using white noise (like a de-tuned FM radio) and adjusting the record head azimuth as you listen to the playback. The biggest danger with any of the home brew test tapes out there is that they are dependent on the set up of the recording deck. Also, as Ron just detailed, the height adjust tape cannot be duplicated on a regular cassette deck. I might also add, the 3kHz wow/speed tape is very dependent on the recording machine. I'm sure Nakamichi made those tapes on a modified open reel deck in order to obtain wow and flutter low enough to be used as a measurement standard. BTW - I recall that there was someone on NakTalk who was working with a Studer open reel transport and was coming close to the ability to reproduce these tapes accurately. Still out there?

Interesting what you say about each side of as cassette having its own error.

The rationale is that some azimuth error is caused by movement of the shell during play. This, is turn, is caused by force transmitted to the shell by the moving tape. By adjusting for zero error at the middle of the tape, worst case error is supposedly halved. OTOH, seeing that force exerted by the tape is infinitesimally small and even the chintziest of shells is seated fairly rigid, this shouldn't be taken too seriously. Personally, I adjust recording azimuth anywhere except very close to tape ends and never noticed HF response variations along a cassette. BTW, purists also adjust azimuth separately for each side. The idea here is that shells are not perfectly flat and, therefore, each side will have it's own error, independent of the other side. This make a lot of sense. When I still owned a 582, I noticed that adjustments for each side were invariably different, though not by much. -- Ron Graham A Nelson wrote: > I recall hearing it said that, when setting the azimuth prior to recording > onto a tape, the process should not be done at the start of the tape but > some distance down the reel.

You can use such a tape but it will give you a higher w/f reading. As per the T-100 manual, you can get a reading in the ballpark by recording a 3K tone on a tape and playing that tape back, then multiply your reading by 0.707 for the roughly correct value. The reference tape should be far below the 0.023% deck specification and the only decks capable of that are r2r machines. With a little luck Victor will be able to produce such tapes when (or if) his life settles down again.

The azimuth adjust on the ZX-7 is for the record head and aligns its azimuth with its own play head. Once done, you can use that tape to adjust the play head azimuth on your BX-300 by looking for maximum play output. At that point you will have matched the play azimuth on the two decks. If it was wrong on the ZX-7 you will have duplicated that error on the BX-300. Presuming it's all correct, you can set the record head azimuth on the BX-300 for maximum high frequency response. The right way to do it is with a signal generator but you can come very close by using white noise (like a de-tuned FM radio) and adjusting the record head azimuth as you listen to the playback. The biggest danger with any of the home brew test tapes out there is that they are dependent on the set up of the recording deck. Also, as Ron just detailed, the height adjust tape cannot be duplicated on a regular cassette deck. I might also add, the 3kHz wow/speed tape is very dependent on the recording machine. I'm sure Nakamichi made those tapes on a modified open reel deck in order to obtain wow and flutter low enough to be used as a measurement standard. BTW - I recall that there was someone on NakTalk who was working with a Studer open reel transport and was coming close to the ability to reproduce these tapes accurately. Still out there?

You can use such a tape but it will give you a higher w/f reading. As per the T-100 manual, you can get a reading in the ballpark by recording a 3K tone on a tape and playing that tape back, then multiply your reading by 0.707 for the roughly correct value. The reference tape should be far below the 0.023% deck specification and the only decks capable of that are r2r machines. With a little luck Victor will be able to produce such tapes when (or if) his life settles down again.

The idler tire is problematic only in some Sankyo transports. The LX-3 does not use this transport. In general, if a Nakamichi deck starts to play, then reverts to Stop within a second or so, take up should be the first function to investigate. To check, remove the cassette door, close the cassette shell and press Play. Observe the take up hub. If it does not rotate, that's your problem right there. Investigate why and correct before going further. If the hub does rotate, touch it lightly with a finger The hub should have enough torque to continue to rotate. If it stops even though you applied a light touch, the take up torque may be too low. Diagnose why and correct. (Usually, this calls for cleaning and/or lubricating. Torque adjustment is rarely required) If OK so far, apply enough pressure to stop the hub. The transport should revert to the Stop mode within about a second. > > > > So, is this something I can do myself? > I have no idea. I expect *you* are the best person to answer that.

Unless badly worn, the deck should still go into FF or RW. 2) If it drops out of any mode within about a second of pressing the control, then chances are the auto stop bulb has failed, also a relatively easy fix on an LX ..though the front panel has to come off it is better than pulling the transport out for other classic transport decks.

Secondly, the 682ZX has auto calibration of bias and level. ( level is manual) besides azimuth. The 680/680zx do not calibrate bias at all. Only azimuth and levels. This makes the 682ZX more desirable than the 680/680zx series decks. I, personally prefer the 680ZX to the 682ZX, only for the sound quality. The 680zx bass IMHO is a tad punchier and more defined than the 682Zx.....but thats just my opinion and no one else may agree. Regards, Ram --- On Fri, 9/4/09, . wrote: From: .

Having worked at Nakamichi dealers since the days of the TriTracer 1000, 600, and 500 I can assure you that the Nakamichis have been the "Gold Standard" on W&F performance. Nakamichi had a good White Paper years ago on W&F and how manufacturers were great at picking the spec to make their machines look good on paper. Nakamichi engineers were the ones to tackle the problem that any resonances in the transport will cause audible distortions. i.e. the Diffused resonance Transport and the tape pressure pad lifter on the playback head. I'm one of those individuals who are highly sensitive to W&F, scrape flutter, etc. Out of curiosity I have given quite a few machines a measure and a listen. I remember years ago when Studer/Revox came out with the B-710 I thought, wow this will be the new standard! The B-710 transport is machined out of a solid billet of aluminum and is built to commercial studio standards. I also owned a couple of Revox R to R decks. Well the B-710 measured wonderful but . . . it fell flat on its face when reproducing music with sounds like sustained piano notes. It was after that that Nakamichi revealed that they had been working on the "cogging" problem of direct drive motors. That is probably what I was hearing in the Revox cassette machines. It was not as much of a factor on the reel decks running at 15ips since the distortion products would have been pushed to the limits of the audio spectrum. I'm digging back in my foggy Broadcast Engineer memory from when I worked at a cassette duplication facility, but I believe most manufacturers of Cassette Alignment Tapes did record the tapes on custom open reel machines that had special head alignment adjusters with Micrometers that allowed precise calibration. I can not remember how Nakamichi alignment tapes were made. I know in broadcast when I was checking head azimuth on studio mastering deck we would use a two-track head stack and record a test tone on each channel, then flip the tape and play back through the record head. We could then repeat the procedure until the tape would play perfectly in either direction. Then we knew that the record head was perpendicular to the tape path. The commercial test tapes were full track recordings and could be used to check the play head gap alignment and head azimuth. Willy's idea is probably the most doable.

After all, there were (probably still are) other cassette manufacturers who could produce decks with better w/f than Nakamichi. Correct me if I’m wrong but I don’t think any Naks bettered 0.023% WRMS, which was the factory spec for Pioneer’s CT-830S and CT-730S decks. Perhaps that would be good enough (assuming a Pioneer could be found in good condition!)? Graham From: naktalk-bounces at naks.com [mailto:naktalk-bounces at naks.com] On Behalf Of Willy Hermann Sent: Sunday, August 30, 2009 7:01 PM To: Talk about Nakamichi Cassette Decks Subject: Re: [naktalk] Test tapes All depends on whether your ZX-7 has been properly adjusted. The azimuth adjust on the ZX-7 is for the record head and aligns its azimuth with its own play head. Once done, you can use that tape to adjust the play head azimuth on your BX-300 by looking for maximum play output. At that point you will have matched the play azimuth on the two decks. If it was wrong on the ZX-7 you will have duplicated that error on the BX-300. Presuming it's all correct, you can set the record head azimuth on the BX-300 for maximum high frequency response. The right way to do it is with a signal generator but you can come very close by using white noise (like a de-tuned FM radio) and adjusting the record head azimuth as you listen to the playback. The biggest danger with any of the home brew test tapes out there is that they are dependent on the set up of the recording deck. Also, as Ron just detailed, the height adjust tape cannot be duplicated on a regular cassette deck. I might also add, the 3kHz wow/speed tape is very dependent on the recording machine. I'm sure Nakamichi made those tapes on a modified open reel deck in order to obtain wow and flutter low enough to be used as a measurement standard. BTW - I recall that there was someone on NakTalk who was working with a Studer open reel transport and was coming close to the ability to reproduce these tapes accurately. Still out there?

As a result, my machine has recorded test tones onto the tape. Could I use those tones to set up my BX300? Could I use the tape on the Bx and adjust the heads until I had playback with equal output for playback azimuth for example? This would be a good way of setting up playback at least. Could anything be done with the record head though?

Isn't there a simple way to do this - Set the levels on the metre sliders the same. Then take any channel from a given source, say the left hand channel of my white noise LP and feed that first to the LH channel of the deck, then the right. That way, a different level on the meters would tell you that either the meters were wrong or the record head azimuth was wrong . Not sure where I go from there though!

Stasis Info Anyone? Message-ID: <552575.13216.qm@web110808.mail.gq1.yahoo.com> Hi Fred, I have two 670zx and love them. One common problem is the meters fail, they get sluggish and then just hang down.  Willy Hermann has figured out how to repair them with a microscope and a steady had. Willy fixed mine and a 660zx as well.  I know Willy sent the procedure to the list some time ago but not sure when.  Note that if you wreck them trying to fix them the only replacement is another deck's meters display - the entire display since it is all one big part!What happens when you turn the deck on and try FF and play without a cassette? David Hi David, YES, the meters are very sluggish and they now both seem to hang down due to gravity, whereas only one hung at -5 previously. The FF seems to work and continues to FF as long as I want her to.  What does this mean?  I hope it's good. In an effort to wake / reheat / burn off musty garage effects on the meters (no success), I noticed that after being on a while, the transport doesn't engage when asked to play / transport sagging...? but will play after being turned off / rested.   I will try to find the meter solution.  If it sounds dicey, looks like the deck is off to Willy. Do you happen to remember about how long ago this was posted?  Thanks for your help.   I would love to get this deck up and running.  I also was able to "save" a couple of Nak Stasis receivers!!!! and they seem to be working beautifully.  Any information on the SR series also greatly appreciated.    Fred in CT -------------- next part -------------- An HTML attachment was scrubbed...

Duration of the pulse should be about 1 Sec (as observed on my CR-7). Make sure yours is truly 3 Sec. If so, it's worthwhile to check and repair. The duration is controlled by RC combination R616 (330K) and C604 (2.2uF) on the mechanism control PCB. Measure both components (note that ESR of C604 is important). If either is seriously out of spec, replace. If both are within spec, you'll need a 'scope to check further.

These machines take special tools and knowhow to work on and "Midnight Joe's TV Repair Service" will likely destroy the machine. I've seen several decks which came to me after local service had "not been able to fix the problem". In each case the decks had internal damage from the attempts. If your deck is a US model the power transformer likely has only a single primary winding and can not be converted to 220. The transformer could be switched but these were parts custom made for Nakamichi and it's unlikely you could find one other than in a deck someone is parting out. Using a step down transformer is not a problem. These decks don't draw much current and there is no reason not to use an external transformer.

I have a couple of Naks that are US spec, bought from a US expat who was stationed in NZ for a couple of years.. they work fine on that step down. You could get a transformer wound, but the DS step down will be way cheaper and doesn't involve monkeying with the deck!!. Sticky pinch rollers are relatively easy to deal with.. just need to be careful re-setting the roller height... I'm a tech bunny and can do this. Mode control belt is a 20 minute job and very easy. I have yet to tackle a bias oscillator.. John Gipps gave me a walkthrough.. just need to pluck up the courage and give it a go...plenty of practise decks around here! A decent tech who cares about these decks should be able to fix any issues you cannot deal with, and of course you can always refer problems back here. When I was living in Oz, I used a so called "Nak specialist" to fix my ZX-7... caused more problems than he fixed, (stuffed up chrome and metal calibration, and when tackled just fed me some BS about head wear and not to use those tape types)..had to have it re-repaired back here in NZ,so paid twice for the same job :o(.. but on the bright side, works wonderfully now. You can always put a query out on Stereonet.. Zaphod Beeblebrox in Sydney will apparently take on a nak.. though never used him myself.. cheers, M ----- Original Message ----- From: .

If so it's most likely one of the "orange drop" poly caps in the bias oscillator. Try changing C321/C322 - two 4700pf caps near the bias coil.

The fix is to take off the face and, using a jewelers screwdriver, loosen the bearing just slightly until it frees the needle - not so much that the movement falls out of the bearing cup.

Cassette recordings of the same thing on my ZX7 do not quite have the weight or solidity, but they are miles better than CD. Pre-recorded cassettes can occassionally work but I'd need a CR7 for a best opinion on these. I can record direct to CD via a Traxdata analog recorder, good but no cigar. Amps are Mullard 520's with EL37's, Croft super Micro three valve pre-amp (telefunkens) , heavily reworked, Spendor BC1's (or Proac Tablets, Rogers JR149) Wish I'd kept my PM7 Lowthers but they were coloured compared to BC1s.

You can use such a tape but it will give you a higher w/f reading. As per the T-100 manual, you can get a reading in the ballpark by recording a 3K tone on a tape and playing that tape back, then multiply your reading by 0.707 for the roughly correct value. The reference tape should be far below the 0.023% deck specification and the only decks capable of that are r2r machines. With a little luck Victor will be able to produce such tapes when (or if) his life settles down again.

The azimuth adjust on the ZX-7 is for the record head and aligns its azimuth with its own play head. Once done, you can use that tape to adjust the play head azimuth on your BX-300 by looking for maximum play output. At that point you will have matched the play azimuth on the two decks. If it was wrong on the ZX-7 you will have duplicated that error on the BX-300. Presuming it's all correct, you can set the record head azimuth on the BX-300 for maximum high frequency response. The right way to do it is with a signal generator but you can come very close by using white noise (like a de-tuned FM radio) and adjusting the record head azimuth as you listen to the playback. The biggest danger with any of the home brew test tapes out there is that they are dependent on the set up of the recording deck. Also, as Ron just detailed, the height adjust tape cannot be duplicated on a regular cassette deck. I might also add, the 3kHz wow/speed tape is very dependent on the recording machine.

Having worked at Nakamichi dealers since the days of the TriTracer 1000, 600, and 500 I can assure you that the Nakamichis have been the "Gold Standard" on W&F performance. Nakamichi had a good White Paper years ago on W&F and how manufacturers were great at picking the spec to make their machines look good on paper. Nakamichi engineers were the ones to tackle the problem that any resonances in the transport will cause audible distortions. i.e. the Diffused resonance Transport and the tape pressure pad lifter on the playback head. I'm one of those individuals who are highly sensitive to W&F, scrape flutter, etc. Out of curiosity I have given quite a few machines a measure and a listen. I remember years ago when Studer/Revox came out with the B-710 I thought, wow this will be the new standard! The B-710 transport is machined out of a solid billet of aluminum and is built to commercial studio standards. I also owned a couple of Revox R to R decks. Well the B-710 measured wonderful but . . . it fell flat on its face when reproducing music with sounds like sustained piano notes. It was after that that Nakamichi revealed that they had been working on the "cogging" problem of direct drive motors. That is probably what I was hearing in the Revox cassette machines. It was not as much of a factor on the reel decks running at 15ips since the distortion products would have been pushed to the limits of the audio spectrum. I'm digging back in my foggy Broadcast Engineer memory from when I worked at a cassette duplication facility, but I believe most manufacturers of Cassette Alignment Tapes did record the tapes on custom open reel machines that had special head alignment adjusters with Micrometers that allowed precise calibration. I can not remember how Nakamichi alignment tapes were made. I know in broadcast when I was checking head azimuth on studio mastering deck we would use a two-track head stack and record a test tone on each channel, then flip the tape and play back through the record head. We could then repeat the procedure until the tape would play perfectly in either direction. Then we knew that the record head was perpendicular to the tape path. The commercial test tapes were full track recordings and could be used to check the play head gap alignment and head azimuth. Willy's idea is probably the most doable.

Graham From: naktalk-bounces at naks.com [mailto:naktalk-bounces at naks.com] On Behalf Of Rainer & Joy-Ell Sent: Tuesday, September 01, 2009 7:30 PM To: Talk about Nakamichi Cassette Decks Subject: Re: [naktalk] Test tapes For starters, if you are using a moving coil cart to play the record the output will not be the same for each channel because of the way the coils are wound (most carts). Some of the higher end carts try to compensate for this by winding the coils with different impedances but I still would never trust the output level from a record to be identical for both channels. ----- Original Message ----- From: John Chapman To: Talk about Nakamichi Cassette Decks Sent: Tuesday, September 01, 2009 8:24 AM Subject: Re: [naktalk] Test tapes Hi Willy, and Ron before, and others I have a test LP record with white noise, recorded, I quote, "nominally -15db ref 1.12 x 10-3cm peak amplitude". Assuming I want the ZX7 as good as I can get it, what do I now do? As this is playing into the Nak, I note that the left hand channel is one segment down on the right with level knobs set at 12 o clock. Do I adjust the record head while listening to the playback of the white noise till they are the same? If I do this, I presume the white noise tape I make can then be used to set up the BX or do I make a tape with test tones now I know the ZX7 is as good as I can reasonably get it. If I presume I could also use the pre-recorded 800hz signal from my Ampex r-to-r test tape instead of white noise. It has 800,1,000,8,000,10,000 and 13,000 hz frequencies Thanks for putting up this if I am asking the obvious.

Li Sent: Monday, September 07, 2009 7:46 AM To: naktalk at naks.com Subject: [naktalk] 670ZX Finds A Good Home..... Stasis Info Anyone? Hi Fred, I have two 670zx and love them. One common problem is the meters fail, they get sluggish and then just hang down. Willy Hermann has figured out how to repair them with a microscope and a steady had. Willy fixed mine and a 660zx as well. I know Willy sent the procedure to the list some time ago but not sure when. Note that if you wreck them trying to fix them the only replacement is another deck's meters display - the entire display since it is all one big part!What happens when you turn the deck on and try FF and play without a cassette? David Hi David, YES, the meters are very sluggish and they now both seem to hang down due to gravity, whereas only one hung at -5 previously. The FF seems to work and continues to FF as long as I want her to. What does this mean? I hope it's good. In an effort to wake / reheat / burn off musty garage effects on the meters (no success), I noticed that after being on a while, the transport doesn't engage when asked to play / transport sagging...? but will play after being turned off / rested. I will try to find the meter solution. If it sounds dicey, looks like the deck is off to Willy. Do you happen to remember about how long ago this was posted? Thanks for your help. I would love to get this deck up and running. I also was able to "save" a couple of Nak Stasis receivers!!!! and they seem to be working beautifully. Any information on the SR series also greatly appreciated. Fred in CT -------------- next part -------------- An HTML attachment was scrubbed...

I've been documenting readings as I have used them and the Sony is almost as low as the Nakamichi test tape....just fine for regular use." * **I don't agree and neither does Nakamichi. On page 13 of the T-100 owners manual they state: "Obviously the record/playback method results in higher figures. Record/playback readings are roughly 1.414 times higher than playback readings." It is logical that if you record a tape on a machine and play it back on that same machine the wow and flutter will be amplified - the w/f caused during the recording process plus that caused in the playback. I would be very surprised if the Nakamichi test tape was recorded on a cassette machine. Willy -------------- next part -------------- An HTML attachment was scrubbed...

I got into Vinyl a year ago and have had several tables since, I have finally settled on one and am very pleased with: VPI Aries, JMW 10 ARM and Dynavector 20XL cartridge. In some cases vinyl and my cassette (BX-300) rivals my CD player but like everything there are good recordings and bad recordings so I cannot say definitively that one is better then the other but I do like the process of listening to records more so then anything else. My wife and I went to purchase a iPod this weekend at Best Buy and was surprised to see that they had a Project Debut III turntable in the AV section and later found an entire row dedictate to NEW vinyl... things are changing, I read a year ago that NEW Vinyl sales in 2007 were at higher levels then in 1980....

The W&F of the tapes should be atleast one tenth of the lowest level measured. However I believe atleast the tape should have less than half of the lowest measurable unit for that to qualify as the test tape. Otherwise it cannot be used - So it cannot be made on any casstte recorder. One way to cheat the W&F will be High SPeed recording using precise Spool recorders of short run I think Kermit had some ideas thrown in earlier about production of such tapes in Naktalk Ron can throw some light on possible ways to make such a measurement tool Kannan --- On Thu, 9/10/09, Willy Hermann wrote: > From: Willy Hermann > Subject: [naktalk] Test tape thread > To: "Talk about Nakamichi Cassette Decks" > Date: Thursday, September 10, 2009, 12:04 PM > Tom - > "I > believe the tapes are mastered on a Dragon, since the W/F > vanishes when testing a Dragon ( a W/F test tape will have > the lowest residual when played back on the same deck) . > I've been documenting readings as I have used them and > the Sony is almost as low as the Nakamichi test tape....just > fine for regular use."   > > I > don't agree and neither does Nakamichi.  On page 13 of > the T-100 owners manual they state: "Obviously the > record/playback method results in higher figures. >  Record/playback readings are roughly 1.414 times higher > than playback readings."  It is logical that if you > record a tape on a machine and play it back on that same > machine the wow and flutter will be amplified - the w/f > caused during the recording process plus that caused in the > playback.  I would be very surprised if the Nakamichi test > tape was recorded on a cassette machine. > > Willy > > -----Inline Attachment Follows----- > > ========---------------------------------------------------------========= >           Also check out the wiki! > http://www.naks.com/wiki > ========---------------------------------------------------------========= >                 >         Naktalk at naks.com > mailinglist > Maintain your account here: http://www.naks.com/mailman/listinfo/naktalk > ========---------------------------------------------------------========= From hitech at birch.net Thu Sep 10 22:21:47 2009 From: hitech at birch.net (tom brucker) Date: Thu, 10 Sep 2009 15:21:47 -0500 Subject: [naktalk] Test tape thread In-Reply-To: <4b6f92900909100904k2d9c5c24i96a6c9f4cdb78278@mail.gmail.com> Message-ID: Willy, It does not make logical sense, but try it sometime. A certain amount of W/F is random, but in a solid mechanism the various vibrations and variances are caused by the tolerances of the parts, hence Diffused Resonance, the staggering of these vibrations. I believe, without any scientific analysis, that the Dragon's W/F cancells or nulls itself when you make a home-made tape this way. In other words, the percentages of random vibrations are very low in Dragons, and indeed, most classic Nak decks. My data from various decks using the Sony WS48 test tape: Dragon 0.04% wtd 1000ZXL 0.05-0.07% wtd CR4 0.06-0.08% wtd BX1 0.09% wtd BX300 0.06% wtd 700 0.065% wtd ZX9 0.05% wtd The Sony tape has no residual specified. My current Nak Da9006C tape doesn't have the residual written down, but I know the older tapes did. Does anyone recall the residual? The ZXL did not have a new belt, BTW. Now that I write this out I realize my information was supplied by the Nakamichi engineers as an answer to my question : How can a deck have lower W/F than the test tape residual? tom brucker -----Original Message----- From: naktalk-bounces at naks.com [mailto:naktalk-bounces at naks.com]On Behalf Of Willy Hermann Sent: Thursday, September 10, 2009 11:05 AM To: Talk about Nakamichi Cassette Decks Subject: [naktalk] Test tape thread Tom - "I believe the tapes are mastered on a Dragon, since the W/F vanishes when testing a Dragon ( a W/F test tape will have the lowest residual when played back on the same deck) . I've been documenting readings as I have used them and the Sony is almost as low as the Nakamichi test tape....just fine for regular use." I don't agree and neither does Nakamichi. On page 13 of the T-100 owners manual they state: "Obviously the record/playback method results in higher figures. Record/playback readings are roughly 1.414 times higher than playback readings." It is logical that if you record a tape on a machine and play it back on that same machine the wow and flutter will be amplified - the w/f caused during the recording process plus that caused in the playback. I would be very surprised if the Nakamichi test tape was recorded on a cassette machine. Willy -------------- next part -------------- An HTML attachment was scrubbed...

But it depends on the CD. Most remastered Cds are a joke and the original vinyl murders it, (JJ Cale hits for example) providing its an original pressing. lately though, I bought Coldplay on 180 gram vinyl and CD and there was little in it. I got Booker T's Soul Dressing, 180 gram re - issue - awesome compared to the CD. Norah Jones is slightly better on vinyl than CD - its generally a feeling of being closer to the music and more depth to the recording. Pink Floyd Echoes was a great remaster but I'd rather listen to the vinyl, pops and whistles as well. Then I got hold of a cassette of Maria Callas - 1957 mono - superb. I have her on CD and vinyl - for once the cassette wins out. Cassette machines have this slight advantage - you can record stuff - and take it to the car and there the Cassette is king - its the nearest you will get to vinyl on the move! By the way I have an ageing Alpine head unit - whoever made the transport knew what they were doing. Its way outlasted the CD box. Cheers all! John Chapman By the way, I would not call a Thorens TD160 humble - a fine deck, only bettered by the 125 and 124.

I'm not a tech, but I didn't find it too difficult. Once you get the clear plastic cover off of the meters you remove the light bulb because the screw you want to loosen is directly behind it. I used the soldering iron to warm the screw as it was glued fast with a drop of paint. Just loosen enough that the meter will fall back to 0. Solder the bulb back in place and you're back in business. My 2 cents for what it's worth...

However, the azimuth calibration have the "counterclockwisë indicator" constantly lit even though I have turned it all to way CC. Level calibration is alright but for bias it could not reach the calibrated levels. The seller told me it was fine before and he could calibrate within 1/4 turn of the knob for Maxell XL2S and MX-S, I also used XL2S and Sony Metal-XR and did not work, as expected the result of the recording was awful and lack of high frequency. Hope anyone could help, since it's nearly impossible to have it fixed here in Hong Kong. Thanks. Rgds, Daniel -------------- next part -------------- An HTML attachment was scrubbed...

Many a times, people associate records with clicks and pops, but not all of them are from scratches. Remember that beneath the seemingly smooth surface are grooves, and dust and dirt particles simply gets trapped in there. Mere brushing won't do. A good cleaning involves giving records a thorough clean the first time round, before settling into a brushing routine. Once you have done that, you would be surprised just how low the noise floor diminishes, and how much more detail can be picked up. I can here even the stop and start of the master tape between tracks on a clean record!

This could run and run! Interesting. IMHO its Reel to Reel - my Akai GX635 with a live broadcast from my 1960 Troughline tuner with One Thing decoder beats my best 180 gram vinyl for space, depth - the sense of being there. Cassette recordings of the same thing on my ZX7 do not quite have the weight or solidity, but they are miles better than CD. Pre-recorded cassettes can occassionally work but I'd need a CR7 for a best opinion on these. I can record direct to CD via a Traxdata analog recorder, good but no cigar. Amps are Mullard 520's with EL37's, Croft super Micro three valve pre-amp (telefunkens) , heavily reworked, Spendor BC1's (or Proac Tablets, Rogers JR149) Wish I'd kept my PM7 Lowthers but they were coloured compared to BC1s. Vinyl is Garrard 401 in timber and acrylic plinth, SME 3009, A& Rp77 retipped by Expert stylus. You are lucky you can hear tape hiss! Now a distant fond memory.

They can usually be bought ,on relative rare occassions on european domiciled eBay sites(NOT US). Knowing the numbering system that Nakamichi uses there should be also be  a CD1 (top dog) CD2 and CD3 as well. The appearance of this deck is in the Nak CR  tape series mould with no"round  modernism" as in the CD Player 1,2,3,4 series. Does anyone have  knowledge of the CD1,CD2 or CD3 ? (correct nomenclature) ? This CD4 beats the daylight out of my OMS7's and presumably the CD1 should do as well. Maybe someone can point me in the right direction?Unfortunately I cannot decipher the Japanese Nakamichi site,which I presume lists this CDseries. walter -------------- next part -------------- An HTML attachment was scrubbed...

To explain: when a continuous test tone is recorded, the W/F is recorded on the tape. When played back, there is an interaction between the W/F already recorded on the tape and the W/F of the machine during PB. This interaction depends on the relative time position of these two components. It is conceivable that they could exactly cancel each other. By the same token, it is just as conceivable that they could add up to produce essentially double the W/F. Obviously, the actual W/F will be somewhere between these two extremes. Statistics tell us that *on the average*, they will be equal to the SQR(2) = 1.414. What is definitely *not* the case is that every time the tape is played, W/F will be canceled -- on the Dragon or on any other deck. The above is true not only when W/F recurs exactly the same every time the deck runs, but also for the stochastic component of W/F. -- Ron tom brucker wrote: > Willy, > It does not make logical sense, but try it sometime.

I seem to recall many claiming the bass in the 682z is so very tight and solid while the highs remains pleasant. Of course, we all have our own auditory recall regarding the definition of 'tight, solid or pleasant'. Arguments aside, many here overwhelmingly give that series a thumbs up. I currently own a Dragon but have owned a CR7A just about five years ago. Certainly the 7A is quite the deck. Now I find myself, like many others here, yearning to add a deck to the collection but have come back to the 680z series and the CR7A as the two most likely candidates. Alas, limited funds will probably rule the sort order of how I choose but for those who own one of the 680z series and possibly the CR7A, is the several hundred dollars difference in purchasing the 7A worth it compared to the 680z series (most likely 682z) worth it? I realize there are just so many models designed and produced by Nakamichi that could be discussed but I'd like to stick with the CR7A or 680 series. I see the going price for a ZX7 to have dropped quite a bit lately and should I add that model in for comparison? FWIW, my Dragon is the absolute king when it comes to a playback deck given that I have owned a CR7A in the past and remember the difference.

First select the correct tape type and recommended eq settings for the tape in use. 2. Next, turn the level and bias knobs for the particular tape in use to their center position. 3. Next turn the source/tape function to source and press the level button to check if the 400HZ sound is displayed a the 0 dB mark on the meters. DO the same with the bias button with the source on....If you have an issue obtaining bias/level signals, you have an oscillator issue( caps of course) 4. If the above goes well, begin the calibration with the tape/source on tape and begin with the azimuth adjustment. Then do the level and then bias and reconfirm all three once again. If azimuth itself is trouble, then you need to check if the azimuth cable is patent throughout. If nothing works, hmmmmm....Willy Hermann/ESL in the USA and B&W In the UK is your best repair resource. Good luck.

First select the correct tape type and recommended eq settings for the tape in use. 2. Next, turn the level and bias knobs for the particular tape in use to their center position. 3. Next turn the source/tape function to source and press the level button to check if the 400HZ sound is displayed a the 0 dB mark on the meters. DO the same with the bias button with the source on....If you have an issue obtaining bias/level signals, you have an oscillator issue( caps of course) 4. If the above goes well, begin the calibration with the tape/source on tape and begin with the azimuth adjustment. Then do the level and then bias and reconfirm all three once again. If azimuth itself is trouble, then you need to check if the azimuth cable is patent throughout. If nothing works, hmmmmm....Willy Hermann/ESL in the USA and B&W In the UK is your best repair resource. Good luck. Ram -------------- next part -------------- An HTML attachment was scrubbed...

If the deck does not reach bias level with the 15kHz, you can use a better tape. And it needs correct alignment from the playback and record heads to record the 15kHz Testtone. first set the playback head, after that the record head to the same trac and azimuth. If you lissen to e perfect recorded tape without dolby, and you can lissen to the high frequences on both cannels, set the azimth to the high level of this frequences, after this the play back head is close to the perfect track and azimuth. Or buy a alignment tape, there are some usefull ones on Ebay.But dont buy the blue one for 11$ from a US Ebay Seller. If the Deck is still recording week, it can have a lot of reasons, but all this comes after the tape track and azimuth. It takes time to set up a ZX-9 If the ZX-9 was not in use for a long time, comming up problems when using it again, are normal.

And when you run out of the supplied cleaning fluid, take one measure of isopropanol, add two measures of distilled water and a drop or two (per litre) of Photographers wetting agent - a very pure detergent - I use Ilford Ilfotol. Use this instead. Its not better but its cheap. You will find Iso quite cheaply by the litre and 5 litre if you go to a boat builder's suppliers that deal in glass fibre. Even better, if you can get it, is 99% pure industrial methylated spirit, not the purple stuff. Hard to find other than in hospitals. This gets all the gunk out of the grooves including the mold release agent from the stamper. It transformed my collection. This mix takes off static too. If you really want a scrooge solution, make up this mix then get some paint pads - at one time the trendy way to emulsion your walls. These pads have very fine short hairs on them. Then lay your album on a flat surface, on a kitchen towel, then use the pads soaked in the mix in a circular motion. Then wash off, ideally in distilled water. The labels dry off well usually. Make sure you keep your albums in a ventilated cupboard to prevent mould build up. You could also add silica gel crystals to help this if your cabinets are sealed which is what you do in museum cabinets. It comes in crystal form of course and also woven into fabric. Silica gel needs reconditioning in the oven from time to time however by drying out in a low oven. Cheers all PS where can I get a new bulb for my ZX7 cassette compartment?

For most people, I recommend a good RCM like VPI or Nitti-Gritti. Use a good amount of RCF to work the dirt out of the record grooves. I usually use a cheaper, home-made mix to do this, rinse with distilled water, then use VPI's RCFs. You are encouraged to experiment, depending on the condition of your records. Once you have cleaned a previously dirty record, change the inner sleeves. I used to use Nagoaka anti-static sleeves, but it is difficult to get them here these days. I am currently using rice-paper sleeves and they seem to be ok. A record clamp, if your TT does not have it, is another good investment that helps the sound in a variety of ways. But I have never liked TTs that feature vaccuum suction - they sound cold.

I have about 750 LPs and very few of them sound better than (or even equal to) any of my 200 CDs, even though cost of the vinyl playing gear is at least 5 times as much as the CD player. Not to mention that playing an LP is a major production effort while listening to a CD requires nothing more than dropping it onto the tray and pressing a button. -- Ron > > Jayson > > --- On *Fri, 9/11/09, Bala Ganesh Chandra //* wrote: > > > From: Bala Ganesh Chandra > Subject: Re: [naktalk] Record industry in a spin over vinyl > To: "Talk about Nakamichi Cassette Decks" > Date: Friday, September 11, 2009, 12:42 AM > > Hi Dia, > > Clean your records!

For your particular situation, I would recommend the 682ZX absolutely. If well calibrated, its a superb deck and you might be using it more and more than even the mighty Dragon! If you do not want dolby C, then the 680ZX is a slightly less expensive alternative and you get a two speed deck that puts many to shame in its half speed mode. However, no bias calibration here too. Good luck on your find.

I currently own a Dragon but have owned a CR7A just about five years ago.   Certainly the 7A is quite the deck. Now I find myself, like many others here, yearning to add a deck to the collection but have come back to the 680z series and the CR7A as the two most likely candidates. Alas, limited funds will probably rule the sort order of how I choose but for those who own one of the 680z series and possibly the CR7A, is the several hundred dollars difference in purchasing the 7A worth it compared to the 680z series (most likely 682z) worth it? I realize there are just so many models designed and produced by Nakamichi that could be discussed but I'd like to stick with the CR7A or 680 series. I see the going price for a ZX7 to have dropped quite a bit lately and should I add that model in for comparison? FWIW, my Dragon is the absolute king when it comes to a playback deck given that I have owned a CR7A in the past and remember the difference.

And when you run out of the supplied cleaning fluid, take one measure of isopropanol, add two measures of distilled water and a drop or two (per litre) of Photographers wetting agent - a very pure detergent - I use Ilford Ilfotol. Use this instead. Its not better but its cheap. You will find Iso quite cheaply by the litre and 5 litre if you go to a boat builder's suppliers that deal in glass fibre. Even better, if you can get it, is 99% pure industrial methylated spirit, not the purple stuff. Hard to find other than in hospitals. This gets all the gunk out of the grooves including the mold release agent from the stamper. It transformed my collection. This mix takes off static too.  If you really want a scrooge solution, make up this mix then get some paint pads - at one time the trendy way to emulsion your walls. These pads have very fine short hairs on them. Then lay your album on a flat surface, on a kitchen towel, then use the pads soaked in the mix in a circular motion. Then wash off, ideally in distilled water. The labels dry off well usually.  Make sure you keep your albums in a ventilated cupboard to prevent mould build up. You could also add silica gel crystals to help this if your cabinets are sealed which is what you do in museum cabinets. It comes in crystal form of course and also woven into fabric. Silica gel needs reconditioning in the oven from time to time however by drying out in a low oven. Cheers all PS where can I get a new bulb for my ZX7 cassette compartment?

Ya Ron, at age 50 I'm finally recording my 450 LP's to the Dragon, ZX-7, 700 II, LX-5, Aiwa ADF-990, and Akai GX-F90. I'm leaving out the two BX-300's, and use them for playback along with the LX-3, RX-202, BX-2 and others! I always preferred the sound of vinyl over CD's. My cassette collection will be organized in A-Z as tapes recorded from vinyl and then A-Z as tapes recorded from other sources. I just recorded Cream's 1968 Wheels of Fire with the Dragon on a Denon HD8. I noticed the Dragon did not calibrate the HD8 fully on the 'SX' position. Perhaps I should have tried the 'ZX' position since Denon calls these HD8's metal particle. Anyway I'm presently listening to the playbak of the recording on the BX-300 (along with Scott Johnson's remote unit) and it sounds fabulous! The cartridges I used (IMO) from best to worst are: Ortofon VMS5E MK II Shure V 15 TYPE IV Stanton 681EEE MK II ADC QLM 36 MK III Gosh, something must be horribly wrong with my 'audiophile equipment'. I have about 750 LPs and very few of them sound better than (or even equal to) any of my 200 CDs, even though cost of the vinyl playing gear is at least 5 times as much as the CD player. Not to mention that playing an LP is a major production effort while listening to a CD requires nothing more than dropping it onto the tray and pressing a button. -- Ron Jayson --- On Fri, 9/11/09, Bala Ganesh Chandra wrote: From: Bala Ganesh Chandra Subject: Re: [naktalk] Record industry in a spin over vinyl To: "Talk about Nakamichi Cassette Decks" Date: Friday, September 11, 2009, 12:42 AM Hi Dia, Clean your records!

Right on the button. But I can't agree on this. The first time I realised that vinyl wiped the floor with Cd was listening in 2000 to a £450 CD player against a Thorens TD 150 which cost £50 from. I was listening to a brand new CD versus a 30 year old LP. The CD seemed to reveal everything heard by the mike but was flat as yesterday's beer and totally unrewarding. The LP sounded like I was in the room with the musician. same recording. I never yet heard a CD that could give a good account of what a violin sounds like. CD is a digital sample of what the ear hears, Lp is a poor substitute for a live recording but at least it has had a few less stages of gegradation. For me only a live recording on tape or, next best, an LP will get you anywhere near either the studio or the auditorium. The gap between CD and LP is closing but its still way off - to my ears at any rate. I have over £1000 worth of CD player hear I hardly ever listen to. My Garrard 401 was from a car boot saleroom and the arm and cartridge cost about £250. I play LP or cassettes long before thinking about a CD. Maybe your 'audiophile gear' is horribly wrong! When did you last change your stylus? Mind it is such a drag taking an album out of the sleeve and putting it onto the turntable. Then there's all that cueing business, cleaning the "needle" wiping the album over - hardly worth it really.

I found the sound character to be different. The 68x sounded 'warm' and a tad bloated. The CR-7 sounded clean and accurate, what some people would call 'clinical' or 'analytical'. Since you owned a CR-7, you must know what I mean. The 582 I owned before the CR-7 sounded somewhere in between, as did the 700 I owned before that. To my ears, Nak decks tend to that 'almost tube' sound, and the CR-7 is more or less unique in its sonic signature. I preferred the CR-7.

If the record or stylus is dirty, or slightly off alignment, no exotic phono stage is going to put the sound back. I have seen high-end Clearaudio tables being ruined by bad alignment while simpler Linns and Thorens shining thanks to correct and thorough set-up. The whole thing is just like cars - once the important things are taken care of, just sit and enjoy the ride till the next service. As I mentioned, get your records clean. I have tried a variety of cleaning systems, all manners of brushes, and other miracle liquids that allow you to 'peel' scratches off records. Nothing works quite as simple as a good, deep setting brush and distilled water to flush the dirt out. The best that worked is my VPI 17F, and trust me guys, its worth the money. You wouldn't believe how much detail the average moving magnet cart produces once you have gotten rid of the dirt and oil that sticks to the playing surface of the record. Get the turntable set-up right, talc the belts, level the table..its always the simple things. Check the cart alignment, and check your tone-arm damping fluid levels if you have them. I always tell my friends, don't upgrade thinking that your system is delivering all it can - more often, your existing equipment can do better.

I think much depends on the care of the recording engineer – seems a lot of the re-issue CDs sound inferior probably because too little care was had in some or all stages if the process, such as not using original master tapes, recording levels, replay equipment and it being up or below spec, etc, etc. There’s a lot we as amateurs with cassette machines can learn from their mistakes! And as for fresh CD’s, again – I suppose much depends on the record label or, indeed, the engineer doing the job. Think 1970s and how many of the LPs produced then were of variable quality, perhaps no less than many CDs today; but there were some excellent ones, as there are CDs today, especially the done-with-care audiophile ones. So, if your CDs sound as good as your LPs but others may judge their collections do not, there are many variables ... that lot and then there are those of the vinyl replay equipment, not to mention the phono preamp ... etc. And then there is the issue of subjective taste! In short, my own view is that it’s too simplistic to say, one is better than the other, just as it is daft to say a ZX9 is better, or worse, than a CR1 or 1000ZXL – there are too many variables. Me? I was the same – couldn’t hear any difference between vinyl and CD; but then I DID notice differences between the cartridges I used on the RD and even more when I acquired a dedicated outboard phono amp. I also have periods when I prefer listening to stuff on my ZX9, and then on CD. But when I go back to the vinyl through a particular combination of cartridge, RP and the outboard phono, I hear a difference which I would define as “better”, but only better for my taste. There again, it might be something to do with the investment on both sides ... £1k CD player (that I bought from the guy who designed it for £350 – it was a hand built pre-production model but exactly the same as the to-market production one) =versus= c.£2k RP (would at today’s new prices, but I got mine 2nd hand and at a fraction of the cost) £300+ RP arm (again, I didn’t pay anything like that ‘cos I got it 2nd hand on a TT I sold, and I upgraded it myself) £500 cartridge (but I got much much less from the guy who made it!) £600 at today prices for an outboard phono amp (but again, I bought it at a fraction of the price) ... so comparisons are a bit apples and pears!!! Nevertheless, both ZX9 AND the CD player acquit themselves well, to my taste, against the vinyl set up. Gosh, something must be horribly wrong with my 'audiophile equipment'. I have about 750 LPs and very few of them sound better than (or even equal to) any of my 200 CDs, even though cost of the vinyl playing gear is at least 5 times as much as the CD player.

The device has these feisty goatshair brushes which interface with the record surface in the bath of fluid. You rotate the album on the clamp a few turns and then unscrew and put them on the drying rack that comes with it. I can do albums 1 per minute. They are playable in maybe half an hour when dry. I just bought replacement brushes from the excellent Diverse Vinyl in Wales. It was well reviewed in Hi Fi World too. I live in Cornwall, UK with the sea all round and consequent rain. Damp in clothes cupboards and mold on clothes is common place. When I got the machine, I had lots of mold on the records which had been in storage while we moved. The device got rid of it. It is a curious thing though that you can not tell whether a record will clean up. I buy lots of records from charity shops and many an album looks good but maybe has been damaged by use with a damaged cartridge. Nothing will help with that. The thing is at 50 quid, its not going to break the bank. In ideal circumstances, you would have two, one to clean and once to rinse. Another point - re your comments about CD versus vinyl - the software is so cheap with vinyl - average price is 25p per album in charity shops! Helps pay for the record player over the long term.

I would listen to a cassette made from a CD before I would listen to the actual CD. Don't know the actual physics of it but digital to analogue tape process seems to get rid of the horrible digital fog/haze that shits me to tears. Don't know if this is just me, please tell me I'm not alone in this feeling. Good tape seems to me to be the absolute best medium bar none, closely followed by vinyl and IMHO the rest plain sucks.

The first time I realised that vinyl wiped the floor with Cd was listening in 2000 to a £450 CD player against a Thorens TD 150 which cost £50 from. I was listening to a brand new CD versus a 30 year old LP. The CD seemed to reveal everything heard by the mike but was flat as yesterday's  beer and totally unrewarding. The LP sounded like I was in the room with the musician. same recording. I never yet heard a CD that could give a good account of what a violin sounds like. CD is a digital sample of what the ear hears, Lp is a poor substitute for a live recording but at least it has had a few less stages of gegradation. For me only a live recording on tape or, next best, an LP will get you anywhere near either the studio or the auditorium. The gap between CD and LP is closing but its still way off - to my ears at any rate. I have over £1000 worth of CD player hear I hardly ever listen to. My Garrard 401 was from a car boot saleroom and the arm and cartridge cost about £250. I play LP or cassettes long before thinking about a CD. >Maybe your 'audiophile gear' is horribly wrong!

The turntable is a Dual 5000 (one of Dual's best), with a Shure V-15VMR cartridge, absolutely correctly aligned (it comes with a protractor gismo that makes this a cinch) and a pristine stylus (I have a microscope). The preamp is a Hagerman Bugle, that I personally built, using high quality parts. Total cost on ebay would be just under $1000. The CD player is a Denon CDM-560, that you can pick up on ebay for maybe $50. I also have a Pioneer DV-59AVi DVD player (single drawer) that sounds slightly better. Goes on ebay for maybe $250. As you can see, the record playing equipment value is about 20 times the CD player cost and about 4 times the DVD player cost. All the above feeds an Integra Research RDC-7.1 preamp -- a well known and respected piece -- driving 5 channels of Aragon 8008 into a set of Aerial acoustics (10T, CC3, SSR3) speakers and a Velodyne 15" sub. While it has its own built in phono stage, I find the Bugle is slightly better in terms of cleanliness of sound, clarity and accuracy. As to the LPs -- they spend time either on the turntable or in double sleeve, closed cabinet storage. Most were bought new, cleaned by hand, then never given a chance to become dirty. Many have had Sound Guard treatment, though by now it could have been worn off. Listening to the above and using my personal ears to evaluate, I still maintain that most CDs sound better than most LPs. Sure, there are quite a few exceptions, but the rule remains. -- Ron Bala Ganesh Chandra wrote: > Ron, > > The major problem here could be getting to the basics more then > getting a more expensive cart or phono stage.

I think you've hit the nail on the head, Graham. Example in point: I have all G&S operas on London LPs from the 60s. Listened to them a lot. One day I decided to replace them with CDs of the exact same performances, on the premise that quality of London's dubbing equipment should certainly surpass mine. I started by getting Patience and Yeomen and was greatly disappointed. The yo-yo that made the transfers did a horrible job. Compared to the LPs, the sound was stifled, lifeless and distorted. He must have used his grandma's Victrola. (That, BTW, was my last attempt to replace LPs with corresponding CDs.) Needless to say, I kept the LPs. Moral: any yahoo can screw up any technology. This does not mean the technology is deficient, just that the yahoo is. -- Ron Graham A Nelson wrote: > > (Keeping on topic!)

But Ron's point is - should you need to spend so much time just to play music when you can sling a CD on. It was only when I set up my system in a decent room with speaker stands, good cable and good turntable isolation that the old TD150 showed my Rotel 965 BX LE a clean pair of heels. Until your speakers, whatever they are, are in the right place, you'll never know what a system is capable of. Previously, my Proac Super Tablettes were on shelves and I was quite unaware of how good the turntable was. I suddenly realised what I'd been missing when I put them on weighted Atacama stands spiked to the floor about 18 inches from the wall. It was gob smacking and all I had spent was ther cost of the stands and some time spent experimenting with speaker position. Suddenly I realised there were good albums and bad, sound wise. Once set up properly, assuming you have an amp with a half way decent phono stage, a 300 buck record player should see off a 300 buck CD machine, assuming you have decent records to play. Thats not to say there aren't dreadful pressings and great CDs but I reckon 7 out of 10, your going to prefer the 3d quality and holographic imaging that vinyl can give you. But you are going to have to put some time into record care and replacing stylus every 1000 hours, but that's playing about 1500 albums. At 5 a week, that's about 6 years, by which time the laser in the CD machine will probably need replacing if the transport still functions. But I bet you will still be able to get a new drive belt for the Thorens, and you can bet your bottom dollar that the 300 buck CD player is in Dodo land and is non- serviceable. And that's also assuming CDs will still be in production. And while you can always play a scratched record, once you scratch a CD, that's it. So although vinyl may be costly to set up, long term maintenance costs, especially of belt drive decks and arms, are minimal and can be undertaken even by dunderheads like me. What's more if you invest in hand built valve amps, the same applies. My 1960 Leak has just been serviced and is good for years. My Croft integrated does not even have PCB's in it so every part can be replaced. The mullards have been rebuilt and are good for another ten years. Which is why we need people like Ron to keep our complicated Naks in order.

Many reissues of older albums onto CD that were done in the eighties were poor digital masters. Whether one blames the technology, the ears of the engineer, or the quality control -- who knows. Nowadays new CDs sound bad because everything is compressed way too much so that some sound is still there when converted to mp3s. There was a period in the nineties when cassettes were no longer available when CDs were the best format around. The technology was developed enough, and the masters were generally done well. In the eighties a lot of vinyl done poorly too. Cheap thin recycled vinyl. When I compare commercial release on vinyl, cd and cassette of certain albums froms from the period 83-91 or so, often the cassette sounds best. Cassettes required much less alteration of the sound compared with the original 2 track tape master to fit the format. Vinyl requires heavy eq (RIAA curves) and CDs analog to digital conversion. Now for my taste, I prefer to listen to cassettes over other formats for myriad reasons. I record my LPs and CDs to cassette. I generally prefer the sound that comes after transfer better than the original. However, I can't say this is due to "high fidelity" otherwise it would sound exactly the same. It's because it transforms the sound in a way that I find pleasing. I like having the ability to shape the source to my tastes by selecting what kind of tape and the settings for the recording. I also find it nice to have 90 minutes of music set up at one time, and watching my rx202 flip the cassette. :-) From shantiram2000 at yahoo.com Sun Sep 13 22:22:04 2009 From: shantiram2000 at yahoo.com (shanti ramachandran) Date: Sun, 13 Sep 2009 13:22:04 -0700 (PDT) Subject: [naktalk] ZX-9 failed to calibrate In-Reply-To: <7e5e2f880909120504t603dfe7bxf5bac7e890f72965@mail.gmail.com> Message-ID: <997933.67774.qm@web36802.mail.mud.yahoo.com> HI Daniel,   Open the deck's cover and then look at the blue azimuth cable. When you power the deck on and put the deck into azimuth mode, twist the adjustment knob and see if the cable has some motion and also if the head( record) rotates side to side when you are doing this.   If there is no motion there is a mechanical issue.   Finally in the source mode is there zero db 400Hertz tone?   Good luck. ram   --- On Sat, 9/12/09, Daniel Sun wrote: From: Daniel Sun Subject: Re: [naktalk] ZX-9 failed to calibrate To: "Talk about Nakamichi Cassette Decks" Date: Saturday, September 12, 2009, 8:04 AM Hello Ram,   I 've tried the steps below and at step 3 and when I press the level button for 400hz it could reach the -1 mark but not the 0db mark.

First select the correct tape type and recommended eq settings for the tape in use. 2. Next, turn the level and bias knobs for the particular tape in use to their center position. 3. Next turn the source/tape function to source and press the level button to check if the 400HZ sound is displayed a the 0 dB mark on the meters. DO the same with the bias button with the source on....If you have an issue obtaining bias/level signals, you have an oscillator issue( caps of course) 4. If the above goes well, begin the calibration with the tape/source on tape and begin with the azimuth adjustment. Then do the level and then bias and reconfirm all three once again. If azimuth itself is trouble, then you need to check if the azimuth cable is patent throughout. If nothing works, hmmmmm....Willy Hermann/ESL in the USA and B&W In the UK is your best repair resource. Good luck.

The members of this nice forum do know you as Nak spezialist. My I ask you a difficult question ? one of my ZX-9 does switch off the testtones when I switch from souce to tape. If I tuch the point 86 ( up ) on the main PCB with some metal and leaf this point again, than the testtones start again. this point goes direct to the counter PCB. But even this counter PCB did I get get changed, it did not helb. IC-309 and IC-310 are new, and the CE-cups in the main PCB are new. It takes close to a secound, if I switch to tape, than both testtones are getting switched off. If I take the switch PCB from ground, this error does not exist anymore! The IC-309 schould switch from plus 12 Volt on 12 to plus 12Volt on 13 on IC309, but he does it only If I tutch the IC 309 on 11 or to the point next to this, the point 86up. My be you have a idea!

The weak link is probably the dual. Here in the UK it was not well received, rated inferior to the Rega Planar 3 - a cheap but good middle of the road deck which I auditioned in 1988 against an original Systemdek with RB300 and denon 103 cart, which I bought. I sold this for the first of my Linn Sondeks, (one of which had a DC motor) then went back to the Thorens range, of which I have had 3 TD150's, a 160 and two 125's, as well as numerous other makes inc B & O, Technics (radial arm), Sansui, Pioneer etc. The 150, which I kept, is, once properly sorted perhaps the best. I preferred its precision to the woolly bass of the Linn. The Garrard 401 is in another class, however, with bass of an awe inspiring level well below what CD is technically capable of producing. You can buy a TD 150 for peanuts. It needs work but the bearing is superb. It just needs good damping. An SME 3009 with your cartridge, preferably rewired with 10 bucks worth of Cardas cable would be really something. It would be worth sending your VXMR to Expert Stylus, when the time comes, for them to re-tip it. (I spoke with them recently - they advised me against buying a VXMR unless I knew the cart itself was OK, but they felt it was the best MM cartridge ever made). They retipped my V15 III and A & R P77 (another overlooked gem). Postage to the UK would be peanuts for such a small item and they, in my opinion, are world leaders in cartridge re-tipping - they recently retipped the Shure VXMR's resident in Abbey Road studios and are official agents for B & O and Shure in the UK, not to mention being remarkably cheap. My A & R was around 80UKP Anyway, whatever the Dual may be worth as an admittedly nice piece of engineering, I suspect it is that which prevents you from releasing what is in the grooves. What is it sitting on, by the way? The only reason that everyone raves about Garrard decks now is that someone (Loricraft or Bastin) made a decent plinth for them to absorb the hum and rumble. Same with the over expensive 124. Once I got my TD 150 on a decent wall mounted shelf it just took off. However, your Dual was good enough to make you realise what cruddy jobs people make of Cd transfers, so it can't be too bad. I have the G & S Decca recordings of Pirates, Gondoliers and Mikado by D'Oyly Carte on original cassettes by the way, which I never play. Are you interested? In fact I have two sets of the Pirates for some reason and I have to get rid of stuff that I never use like the 7 remaining record decks and six r -to-r's. I wish I had a Cr7 which must be the best way to listen to pre-recorded stuff. Hope this is of some help.

I am located at the other side of the pond (MA, USA). I'll do some searches to see whether this cleaner is available here. I am well aware of the low cost of LPs. Also, availability of material that will never make it to CDs. The reason for my sudden interest in deep cleaning is a recent purchase of a bunch of records ($1 a piece), that looked good until I tried to play them. I can't justify several hundred $$$ for a Nitty Gritty or VPI cleaner, but this one may hit the spot. -- Ron John Chapman wrote: > Hi Ron > > In my experience, yes.

They were baaaad! Drop outs and shells so badly constructed having to reset the azi' for both sides of the tape is a given. Compared to my MA-XG's ... can't hold a candle to them. (I seem to recall some of the more recent SA's were made in Mexico for the N American market? Anyone confirm? Are they better, or just as bad as the European ones?) I've used my SA's on stuff that doesn't require critical listening, mostly to play on the cassette player in my noisy Ford Fiesta car.

First suspect would be, as you suggest, the idler tire. Another suspect is the reel motor. Far less common, but possible, would be an electronic problem with the reel motor driver or some hindrance to rotation (reel hub or even a bad cassette batch). I would start by replacing the idler tire and a * thorough* cleaning of the reel motor pulley (the brass thingy) and hubs.

An interesting article is here.  http://www.recordproducer.com/?a=56&nl=1. Slightly off topic.  I, well actually my wife inherited 5000 + mainly jazz and music hall, some blues 78s from the 20s, 30s, 40s.  These had been stored badly and were/are covered in soot, sand and general grime.  In other words most were filthy.  I have started to clean these by using an ultrasonic tank.  I immerse them in distilled water, 15 at a time, but not far enough for the lable to get wet.  They are suspended on a rod through there centre.  They are seperated from each other by rubber bath tap washers.  In other words the ultrasonic explosions are able to get to both sides of each record.  I turn them a quarter of a turn per minute of ultasonic, so after 4  minutes, I have 15 cleaned records.  I then dab them with kitchen towel and put them in an old fasioned wire record rack to dry for 24hrs, before playing, then I put them in new sleeves.  Old sleeves are kept, but not used.  I have used the same technique with very dirty charity shop bought vinyl.  The records come out nice and clean and play very well. --- On Sun, 13/9/09, bgg at nym.hush.com wrote: From: bgg at nym.hush.com Subject: [naktalk] CDs, vinyl and cassettes more than the medium To: naktalk at naks.com Date: Sunday, 13 September, 2009, 4:43 PM A large part of what gives CDs a bad reputation is how few of them were mastered well for the format.  Many reissues of older albums onto CD that were done in the eighties were poor digital masters. Whether one blames the technology, the ears of the engineer, or the quality control -- who knows.  Nowadays new CDs sound bad because everything is compressed way too much so that some sound is still there when converted to mp3s.  There was a period in the nineties when cassettes were no longer available when CDs were the best format around.  The technology was developed enough, and the masters were generally done well.     In the eighties a lot of vinyl done poorly too. Cheap thin recycled vinyl.  When I compare commercial release on vinyl, cd and cassette of certain albums froms from the period 83-91 or so, often the cassette sounds best.  Cassettes required much less alteration of the sound compared with the original 2 track tape master to fit the format.   Vinyl requires heavy eq (RIAA curves) and CDs analog to digital conversion.     Now for my taste, I prefer to listen to cassettes over other formats for myriad reasons.  I record my LPs and CDs to cassette. I generally prefer the sound that comes after transfer better than the original.  However, I can't say this is due to "high fidelity" otherwise it would sound exactly the same.  It's because it transforms the sound in a way that I find pleasing.  I like having the ability to shape the source to my tastes by selecting what kind of tape and the settings for the recording.  I also find it nice to have 90 minutes of music set up at one time, and watching my rx202 flip the cassette. :-) ========---------------------------------------------------------=========           Also check out the wiki! http://www.naks.com/wiki ========---------------------------------------------------------=========                         Naktalk at naks.com mailinglist Maintain your account here: http://www.naks.com/mailman/listinfo/naktalk ========---------------------------------------------------------========= -------------- next part -------------- An HTML attachment was scrubbed...

One possibility is a hairline crack on PCB traces. Does gently flexing PCBs make the problem come and go? Another possibility is an intermittent cap or resistor. If you have a signal tracer (or similar tool) try to trace the test tone from the oscillator output onward and see whether the oscillator itself is at fault on the tone gets lost on the way. To do this, one must have the service manual handy.

Two of them didn’t sell even for a Buy It Now @ $32.99 and the other two did sell for $48.77 and $39.99. Two out of four suggests there’s not much of a market for them at those prices. But note, those that sell did not have a Buy It Now option, which would seem to support Walter’s view that their prices rose to where they did probably due to bidding fervour. There be a lesson for anyone wanting to sell their stock! But I recall some guy in Manchester (UK) had a large stock of them when TDK withdrew the range and at the time he was selling them at c. £9.00 a cassette, which by today’s prices is around $15 each. (I think he may have bought them at around £4.50 a go as I recall one wholesaler did flog them off at that price, and they vanished off the shelves mighty fast.) Maybe he should have hung on to them a bit longer. Nevertheless, the price now is not a lot different from the old retail cost of them in the UK shops when they were in production – c. £20 each, which is about $33.00 So, rarity value isn’t quite as good as it might seem except for those who bought them @ £9.00 a shot, who may be able to double their money if they sell now. However, one might wonder how long that will last, as the numbers of quality cassette decks continues to diminish - “expensive” cassettes as these may then be worth much less than even £9.00 a shot.

Also, get yourself a TT with variable speed so that you can take it a few notches below 78 rpm and above it as, again, you will find some record companies cut their records at different speeds! (I use a Goldring Lenco GL78 or GL78.) To give you an idea of the differences, here's the Eq curve for the modern vinyl LP: riaa_ccirtn Now, here's the eq' curve for Columbia (English cuts), EMI and HMV emi_hmvtn Others are not so different on the chart but, nevertheless, do sound different when they are played back at the correct settings. The Jazz Club offers many variations of Eq' settings such that you'll be hard pressed not to find one to suit every 78 rpm record you have.

My findings are the same. First comes cassette, closely followed by vinyl then CD. I haven't gone down the path of super CD yet. I also find that by recording CD to cassette, the recorded cassette sounds better. An interesting article is here. http://www.recordproducer.com/?a=56 &nl=1. Slightly off topic. I, well actually my wife inherited 5000 + mainly jazz and music hall, some blues 78s from the 20s, 30s, 40s. These had been stored badly and were/are covered in soot, sand and general grime. In other words most were filthy. I have started to clean these by using an ultrasonic tank. I immerse them in distilled water, 15 at a time, but not far enough for the lable to get wet. They are suspended on a rod through there centre. They are seperated from each other by rubber bath tap washers. In other words the ultrasonic explosions are able to get to both sides of each record. I turn them a quarter of a turn per minute of ultasonic, so after 4 minutes, I have 15 cleaned records. I then dab them with kitchen towel and put them in an old fasioned wire record rack to dry for 24hrs, before playing, then I put them in new sleeves. Old sleeves are kept, but not used. I have used the same technique with very dirty charity shop bought vinyl. The records come out nice and clean and play very well. -------------- next part -------------- An HTML attachment was scrubbed...

Expert Stylus don't have a web site as such but this link says it all really and has the contact number. We dont have much going for us these days in the UK but this firm is a throw back to the days before accountants ruled the world and Hi Fi designers just tried to make products that sounded as good as they could get them, rather than concentrate on the looks of the box. When you talk on the phone to them, you imagine them taking out a fountain pen to take down your details. http://www.stereophile.com/phonocartridges/1098koetsu/index3.html In my last email, I mentioned the G & S cassettes. After sending the email, I put one on - these are Decca recordings - always a good start - from 1984 -and boy were they sharp. I have recently learned via Willy that I have probably upset the set up of my ZX7 by twiddling the playback head set up for a previous tape, so I have probably moved it away from perhaps a factory set up, so it was a nice surprise how good these recordings were and I believe I have now found I rather like Gilbert and Sullivan. If you had not mentioned them, Ron, I might never have listened to these lovely tapes.

I am a new Nak owner, although I had a BX-100 many years ago. I came upon a beautiful 681zx recently that is in need of a good servicing (belts, cleaning/degreasing/regreasing, proper setup, etc). The trouble is, while I know of a few decent tech in the US, I am up in Toronto and I would much rather deal with someone locally than take the risk of shipping across the border. Does anyone know any good techs in the Toronto/Southern Ontario area who are experienced and have all the right Nak tools? Thanks!

The amplifier used is an old mono Newcomb with various different equalization settings. However I would like to upgrade this in the future and it will either be a homebrew.  ESP can supply a printed circuit board for their design of phono stage.  Or it will be ready built, yes Graham Slee Jazz Club Phono Stage is one that I have drooled over in the past. Expert Stylus address and tel no; here.  Very good service and good value for money.  Styli and Cartridges. -------------- next part -------------- An HTML attachment was scrubbed...

I took a look at the idler tire and cleaned it off with some rubber renew and the brass drive pulley with some alcohol. Seems O.K. again. I ordered a new belt set which I should have mentioned includes a new idler tire, so I will change it over if it grief's me out again. Jeff. Jeff C. wrote: > My cr-7 had/has a couple issues.

First suspect would be, as you suggest, the idler tire. Another suspect is the reel motor. Far less common, but possible, would be an electronic problem with the reel motor driver or some hindrance to rotation (reel hub or even a bad cassette batch). I would start by replacing the idler tire and a * thorough* cleaning of the reel motor pulley (the brass thingy) and hubs. If no improvement, I would take it from there. -- Ron From gabrenas at math.utah.edu Wed Sep 16 22:24:21 2009 From: gabrenas at math.utah.edu (Victor Gabrenas) Date: Wed, 16 Sep 2009 14:24:21 -0600 Subject: [naktalk] Who is ash_win?

Kannan!! :-) Message-ID: <4AB23D16.9020406@sbcglobal.net> Hello Nakkers! I have been following this forum for years. Kannan has helped me to fix myself several Naks by aiding in troubleshooting and finding parts for my Naks. But I never mess with my Dragon. That goes strait to Kannan. All I can do is screw it up. I have a decent handle on my limits. Well the Dragon needed a new idler wheel. It was also due for a check up and alignment. I use it allot and enjoy it very much. Kannan was able to get it fixed quickly, but I was going on vacation so I really was not pressed to have it back. I had just recently recapped an old Luxman integrated amp and I used Nichicon Ka series audio caps where I could, or other Nichicon audio caps where there were no KA series available. The Luxman sounded absolutely wonderful after the recap. Better than I ever remembered it sounding. I was a bit skeptical, so I took out a couple of the Nichicons that were sitting close to the output drivers and replaced them with some Panasonics I got at Fry's. The sound changed and not for the better. So I put the Nichicon audio caps back in and I liked the amp so much I put it back to service in place of a Dynaco tube amp in small system. So I suggested to Kannan that since he had my Dragon, I would order the caps that he thought would most benefit the sound. Kannan suggested which ones to replace based on the circuit. And I also wanted the power supply recapped. He did the work and shipped it back to me. He never told me what he thought of the sound. He waited for my reaction. Well it looks like he used part of my email in his Ebay advertisement. I was truly surprised and amazed at the transformation. It has always been a very nice sounding deck, but this took it to the next level. What I thought was always the the euphonic sound of tape, the slight plumping of the bass, the slight compression, was just about gone! I was thrilled. Some of my audio buddies came over for a listen, and one of them has already sent his cr7a to Kannan and had it recapped. He is equally thrilled. I have 2 other friends that are getting their Naks ready to send off to Kannan for a recap also. So it was a change in sound that was heard and deemed worth spending the money to have the caps replaced. Now I am sure much of the change comes from just getting 20 year old caps out of the circuit. But the new caps are probably better in a measurable way than the ones that were stock. For back ground.... I play drums. I have a home studio and record analog to a Tascam TSR 8 , eight track reel to reel. I mix to an Otari MX 5050 B III at 15 ips, 2 track. I also record for the local high school band. I use either my Otari or my Alesis Masterlink at 24/96, direct to 2 track with Earthworks mics and a Earthworks Mic preamp. My playback system is : Sonus Faber Amati speakers, Convergent Audio Technology Ultimate preamp and Convergent Audio Technology JL-1 mono block amps. I also use a pair of REL Stentor II subs. I use Cardas Golden Cross cables and interconnects, some Siltec cables. My turntable is a Basis Debut with vacuum, Basis Vector Arm, and Koetsu Urishi cartridge. This system can reveal subtle changes in micro and macro dynamics. It can play very loud and can sound very live with the right source material. The dragon can now hold it own with the Otari for all but live mic feeds. There is just no substitute for 1/4 inch tape running at 15 ips, compared to the cassette medium with very hot signal sources. But for everything else, recording SACD's, lp's, direct to disk lp's, the dragon can hold its own. Nakamich really hit this deck out of the park, many years ago. With a good alignment and replacement of the aging electrolytics, it is just about as good as anything out there for recording music.

Power line 'hash' is a popular complaint in California. Absolute Sound had a writer who for years commented on powerline issues and went a long way towards establishing power line devices as a must-have in high end systems. Here in Tennessee, we seem to have too little hash to hear differences, however adding extra filtration can't hurt! Anyone offering mods and upgrades has to have a rational reason or two to sell the upgrades. Perhaps Kannan's mods sound good but his reasoning is flawed. Scientific proof and critical audio listening parted ways years ago. tom brucker -----Original Message----- From: naktalk-bounces at naks.com [mailto:naktalk-bounces at naks.com]On Behalf Of Victor Gabrenas Sent: Wednesday, September 16, 2009 7:19 PM To: 'Talk about Nakamichi Cassette Decks' Subject: RE: [naktalk] Who is ash_win?

My two centavos - I have not much cared for CDs, good engineering or not, except for background music or other non-involved in front of the speakers listening. I have had several CD players over the years - from the early Marantz to Kenwood 1 bit to others. Since I developed a fairly large collection, I was happy to find what is probably the most easy to listen to CD player out there. This was an unexpected surprise, given the original purpose of the Sony design - this is the Sony Playstation 1 and can be had for anywhere on ebay from $20 on up. It's no joke, this is one of the best players out there. I have purchased several for use and for parts, you have to be careful about the condition tho and may have to do a little cleaning and tweaking of the Pots to get them to play right, but when you get it all together the sound is amazing. For my tastes anyway, I hear a much more full middle and very little of the "electronica" that has dogged most of the CD sound vs good analogue sources. If you go hunting for this, and it's cheap to check it our for yourself, you have to get the Playstation 1 Model SCHP-1001, check for the model specifically as it has the great RCA Jack setup used only on the early models, these units had the great chipset- MIPS R3000A-family R3051. Some may have problems with non commercial CDs, but the ones I have cleaned up work well on almost all of my home burned CDs. My vinyl source is from a Music Hall 5.1 TT with Shure V15MVR cartridge, ADCOM 565 preamp, which has a real good phono stage. I have a VPI record cleaning machine which is a must have (or equivalent) which is use regularly. This is still my main musical source for critical listening, but when its CDs, I go to the ex-video gamer device every time. My old CD players are boxed up and are no longer used. So, for those that gave up on CD players because of harshness and lack of subtle detail, this is a good alternative.

I forget who the big component reviewer was at the time but he was considered the guru of stereo equipment reviews. I recall amplifiers in the late 70's were approaching THD levels of less than 0.1% We can only accurately hear distortion levels of 0.5%. Ah, so the debates began in furor. The Stero reviewer saw no reason to favor, meaning 'spend more', one amp that was 0.01% THD over one that was 0.001% as long as their response was as close to ruler flat and have acceptable slew rates which I think was at least 25V/usec. > Scientific proof and >critical audio listening parted ways years ago. > >tom brucker >-----Original Message----- >From: naktalk-bounces at naks.com [mailto:naktalk-bounces at naks.com]On >Behalf Of Victor Gabrenas >Sent: Wednesday, September 16, 2009 7:19 PM >To: 'Talk about Nakamichi Cassette Decks' >Subject: RE: [naktalk] Who is ash_win? > > >Kannan, > >http://cgi.ebay.com/Nakamichi-Dragon-Cap-Upgrade-Calibration-Tuning-spl_W0QQ >itemZ280395418498QQihZ018QQcategoryZ4784QQssPageNameZWDVWQQrdZ1QQcmdZViewIte >m > > >"Secondly it reduces HF impedance on power lines and opens up the HF >response with clean low noise background" > >Care to back that statement up mathematically?

I use a Music Hall cd25.2 CD player and swear by their workmanship, though you'll want to make use of the available output for an external DAC if you're *really* picky. My turntable varies between a Thorens TD-165 and a Numark Pro TT1, both with Shure M97xE carts, though I hope to have a pristine Dual 1019 I recently bought up to snuff soon (I might need another pair of eyes on that thing after all, Kermit). To alleviate some of the harshess of the "Redbook" CD sound I will mess with the EQ and oftentimes, at least with older players, I used to feed it through a 3BX deck with some odd expansion/transition settings to add some character to the sound without necessarily muddying it up. At this point I should also add that I'm a big fan of the HDCD spec in general and Keith Johnson's work with Reference Recordings in particular. -Tim On Sat, Sep 19, 2009 at 11:16 AM, RSB wrote: > Its always nice to have a discussion on the merits of digital vs analog, > especially from such well informed and experianced audiophiles.

Also read Erno Borbley' website for his comments on upgrade for parts kannan https://audio.jensencapacitors.com/public/dokumenter/4pole.pdf ------------------------------ The importance of attenuation and high frequency behaviour No matter how fast the amplifiers signal processing circuits are, you cannot utilize that speed if your power supply is too slow to follow rapid signal changes. The power supply's reservoir capacitor constitutes a vital element in the amplifier chain effecting the signals on the main signal paths as well, because the most power amplifiers reservoir is conceptually placed in series with the loudspeaker line. The main issue is not only that, the capacitor can give you enough charge and quickly enough, but the attenuation of the power supply toward the amplifier. In spite of the fact that the audio band is nominally 20-20 kHz, the stability of the amplifier and the overall sound quality is strongly influenced by reservoir capacitor behaviour at very high frequencies. The function of the reservoir capacitor is not only to store energy, but also filtering, providing decoupling between the power supply and the amplifiers signal processing circuits. For energy storage a conventionally constructed aluminium electrolytic capacitor with sufficient Capacitance (F) x Voltage (V)/ Volume (cm3) ratio and satisfactory low ESR and inductivity at higher frequencies would be suitable. However the capacitors filtering characteristic plays a very important role in decoupling and suppressing unwanted transients and other i.e. digital high frequency noises. --- On Thu, 9/17/09, tom brucker wrote: > From: tom brucker > Subject: RE: [naktalk] Who is ash_win? > To: "Talk about Nakamichi Cassette Decks" > Date: Thursday, September 17, 2009, 9:59 AM > Victor, >    I have no affiliation with Kannan other > than to say that he ought to be > familiar with Nakamichi sound. > Power line 'hash' is a popular complaint in California. > Absolute Sound had a > writer who for years commented on powerline issues and went > a long way > towards establishing power line devices as a must-have in > high end systems. > Here in Tennessee, we seem to have too little hash to hear > differences, > however adding extra filtration can't hurt!

I agree with replacing caps is a good thing however changing a cap does not change your HF impedance in your DC power supply. No HF in the DC power supply. After reading the article, I noticed it explains switching mode power supplies. Not the same in a Dragon.

However, the two formats have features that are not necessarily better or worse, just different. Digital audio is far more complex, so sonic quality (of either a specific recording or a specific piece of equipment) is more dependent on implementation. Because digital technology is so involved, certain parts of CD players (mostly, the DAC and LPF) must be of high quality.Yet, again and again, I see people comparing a $5,000 record playing gear (turntable plus cartridge plus phono stage) with a $100 CD player and then conclude that CD technology is inferiour. In my view, in comparing apples to apples (best quality recordings played on similarly priced equipment), CDs are superiour. YMMV. -- Ron RSB wrote: > Its always nice to have a discussion on the merits of digital vs analog, > especially from such well informed and experianced audiophiles.

(They were a cottage industry company around in the 1970s and were probably the first in the UK to make bespoke for hi fi power conditioners, the "virtual battery" and fancy power cables for hi fi with modified plugs.) The company pointed out that it served much like a battery as it isolated the kit to which it was attached from the variability of the good ol' British electric power grid. It was a small but long box that plugged into the power line leading to whatever bit of kit you wished to power. I presume it was simple a box of capacitors! (I have three of them but chosen not to open then as they are riveted closed and I've not wish to drill out the rivets just to peep inside! I first used one with an old 2-headed Aiwa AD1800 cassette deck (which was top-of-the-line in the UK when I bought it.) It made a significant different to the stability of the speed, allowing piano to sound more like a piano than hitherto! It seems to me that more modern hi fi kit tends to be better equipped in the power line within the kit's box as I have not found any audible difference with my Naks, Arcam or Pioneer along the same lines as I found with the Aiwa.

The power supply's reservoir capacitor constitutes a vital element in the amplifier chain effecting the signals on the main signal paths as well, because the most power amplifiers reservoir is conceptually placed in series with the loudspeaker line. The main issue is not only that, the capacitor can give you enough charge and quickly enough, but the attenuation of the power supply toward the amplifier. In spite of the fact that the audio band is nominally 20-20 kHz, the stability of the amplifier and the overall sound quality is strongly influenced by reservoir capacitor behaviour at very high frequencies. The function of the reservoir capacitor is not only to store energy, but also filtering, providing decoupling between the power supply and the amplifiers signal processing circuits. For energy storage a conventionally constructed aluminium electrolytic capacitor with sufficient Capacitance (F) x Voltage (V)/ Volume (cm3) ratio and satisfactory low ESR and inductivity at higher frequencies would be suitable. However the capacitors filtering characteristic plays a very important role in decoupling and suppressing unwanted transients and other i.e. digital high frequency noises.

Actually, on purely technical grounds, CDs are based on a far better technology that LPs. However, the two formats have features that are not necessarily better or worse, just different. Digital audio is far more complex, so sonic quality (of either a specific recording or a specific piece of equipment) is more dependent on implementation. Because digital technology is so involved, certain parts of CD players (mostly, the DAC and LPF) must be of high quality.Yet, again and again, I see people comparing a $5,000 record playing gear (turntable plus cartridge plus phono stage) with a $100 CD player and then conclude that CD technology is inferiour. In my view, in comparing apples to apples (best quality recordings played on similarly priced equipment), CDs are superiour.

I wonder whether newbies won't find it misleading; let alone, confusing. The subject matter itself is factually correct. In fact. it's old hat. But the presentation and wording border on the incomprehensible. Taken literally, much in the article is wrong. For example. "you cannot utilize that speed if your power supply is too slow to follow rapid signal changes." is simply incorrect. However, it's clear that what he meant to say (but didn't), is "... if the power supply is too slow to *avoid* following rapid signal changes." Then he says "...the most power amplifiers reservoir is conceptually placed in series with the loudspeaker line " I don't know what "the most power amplifiers reservoir" means, but the concept is wrong. Actually, it's in parallel, not series. Or, "... the attenuation of the power supply toward the amplifier." What the heck does that even mean? Bottom line, you can replace all this verbiage with "Power supply caps should have low ESR and good HF characteristics". Which is why it's a good idea to use better quality electrolytics with film caps in parallel. -- Ron kannan srinivasaraghavan wrote: > please read this article on Jensen'( capacitor) website on influence of Filter capacitor on Audio performance.

Old dry caps have significantly higher ESR, as well as reduced capacitance. IF any power line high frequency stuff gets through the power transformer, a low ESR power supply cap becomes a better AC ground. Likewise any spurrious HF junk induced into or created in digital circuits within Nak is shunted to AC ground "better" with low ESR, or even fresh new caps. My personal view is to give credit to listeners with high resolution stereos when they hear the effects of cap upgrades, but I usually discount the differences (improvement) a bit. Cap changes and upgrades are becomming a staple in vintage audio. I was asked to upgrade capacitors in a Yamaha BX-1 amplifier, which already contained very high quality caps. I can't say that I heard any difference, and the customer reported no differences...but this was far from scientific. I think anyone that can discuss the differences between live recording on a Nak Dragon vs. Otari RtR at 15 ips has my attention when they report what they hear. tom brucker -----Original Message----- From: naktalk-bounces at naks.com [mailto:naktalk-bounces at naks.com]On Behalf Of Victor Gabrenas Sent: Sunday, September 20, 2009 12:53 AM To: 'Talk about Nakamichi Cassette Decks' Subject: RE: [naktalk] Capacitor talk Folks, I am seeing plenty of explanations here but not seeing anything that would support a change in impedance on your power line by replacing caps. I agree with replacing caps is a good thing however changing a cap does not change your HF impedance in your DC power supply. No HF in the DC power supply. After reading the article, I noticed it explains switching mode power supplies. Not the same in a Dragon.

Also read Erno Borbley' website for his comments on upgrade for parts kannan https://audio.jensencapacitors.com/public/dokumenter/4pole.pdf ------------------------------ The importance of attenuation and high frequency behaviour No matter how fast the amplifiers signal processing circuits are, you cannot utilize that speed if your power supply is too slow to follow rapid signal changes. The power supply's reservoir capacitor constitutes a vital element in the amplifier chain effecting the signals on the main signal paths as well, because the most power amplifiers reservoir is conceptually placed in series with the loudspeaker line. The main issue is not only that, the capacitor can give you enough charge and quickly enough, but the attenuation of the power supply toward the amplifier. In spite of the fact that the audio band is nominally 20-20 kHz, the stability of the amplifier and the overall sound quality is strongly influenced by reservoir capacitor behaviour at very high frequencies. The function of the reservoir capacitor is not only to store energy, but also filtering, providing decoupling between the power supply and the amplifiers signal processing circuits. For energy storage a conventionally constructed aluminium electrolytic capacitor with sufficient Capacitance (F) x Voltage (V)/ Volume (cm3) ratio and satisfactory low ESR and inductivity at higher frequencies would be suitable. However the capacitors filtering characteristic plays a very important role in decoupling and suppressing unwanted transients and other i.e. digital high frequency noises. --- On Thu, 9/17/09, tom brucker wrote: > From: tom brucker > Subject: RE: [naktalk] Who is ash_win? > To: "Talk about Nakamichi Cassette Decks" > Date: Thursday, September 17, 2009, 9:59 AM > Victor, >    I have no affiliation with Kannan other > than to say that he ought to be > familiar with Nakamichi sound. > Power line 'hash' is a popular complaint in California. > Absolute Sound had a > writer who for years commented on powerline issues and went > a long way > towards establishing power line devices as a must-have in > high end systems. > Here in Tennessee, we seem to have too little hash to hear > differences, > however adding extra filtration can't hurt!

(They were a cottage industry company around in the 1970s and were probably the first in the UK to make bespoke for hi fi power conditioners, the "virtual battery" and fancy power cables for hi fi with modified plugs.) The company pointed out that it served much like a battery as it isolated the kit to which it was attached from the variability of the good ol' British electric power grid. It was a small but long box that plugged into the power line leading to whatever bit of kit you wished to power. I presume it was simple a box of capacitors! (I have three of them but chosen not to open then as they are riveted closed and I've not wish to drill out the rivets just to peep inside! I first used one with an old 2-headed Aiwa AD1800 cassette deck (which was top-of-the-line in the UK when I bought it.) It made a significant different to the stability of the speed, allowing piano to sound more like a piano than hitherto! It seems to me that more modern hi fi kit tends to be better equipped in the power line within the kit's box as I have not found any audible difference with my Naks, Arcam or Pioneer along the same lines as I found with the Aiwa.

There are so many variables from source material, i.e. studio practices, to listening environment, to humidity in the air that the debate should go on forever! ;o) My wife and I do have fun listening with friends to both CD and LP and occasionally a 2nd Gen copy of reel master tapes. Earlier this summer we had a professional drummer/singer and her husband over listening to music on our Hi End system. Threshold Audio Pre and Power amps driving Wilson Audio WATT/Puppy system with Mark Levinson CD Transport and DAC. She loved the sound of her favorite CDs. Then my wife smiled and told me to spin some vinyl on the Micro Seiki 1500 with a SAEC Tonearm and Talisman Cartridge. (Roughly $8000 for the Digital front end and $4000 for the Vinyl system) I put on a standard issue Dire Straits Brothers in Arms album. Our friends jaw hit the floor and she said, "Wow! Now that's how I hear the drum kit!" They came over again recently to listen and she had an album from the jazz music school where she attended in the '70s. I cleaned it up on the Nitty Gritty and put it on. (It was a direct to disc recording!) All of our jaws hit the floor!!! Much fun indeed!! I'm not anti CD, I just realize that there is a lot of wonderful music to be had by dragging a rock through those black vinyl grooves!

Actually, on purely technical grounds, CDs are based on a far better technology that LPs. However, the two formats have features that are not necessarily better or worse, just different. Digital audio is far more complex, so sonic quality (of either a specific recording or a specific piece of equipment) is more dependent on implementation. Because digital technology is so involved, certain parts of CD players (mostly, the DAC and LPF) must be of high quality.Yet, again and again, I see people comparing a $5,000 record playing gear (turntable plus cartridge plus phono stage) with a $100 CD player and then conclude that CD technology is inferiour. In my view, in comparing apples to apples (best quality recordings played on similarly priced equipment), CDs are superiour. YMMV. -- Ron RSB wrote: > Its always nice to have a discussion on the merits of digital vs > analog, especially from such well informed and experianced > audiophiles.

Having worked in two-way radio has shown that shielding plays a huge part of reducing noise and intermodulation. From what I have gather from this group comments, the only evidence of replacing the caps would be to stabilize the DC not from HF but dried up caps. Usually this means leaky caps.

I agree with replacing caps is a good thing however changing a cap does not change your HF impedance in your DC power supply. No HF in the DC power supply. A high impedance of supply rails at some high frequency could lead to coupling between stages, causing instability (ringing or even oscillation).

I wonder whether newbies won't find it misleading; let alone, confusing. The subject matter itself is factually correct. In fact. it's old hat. But the presentation and wording border on the incomprehensible. Taken literally, much in the article is wrong. For example. "you cannot utilize that speed if your power supply is too slow to follow rapid signal changes." is simply incorrect. However, it's clear that what he meant to say (but didn't), is "... if the power supply is too slow to avoid following rapid signal changes." Then he says "...the most power amplifiers reservoir is conceptually placed in series with the loudspeaker line " I don't know what "the most power amplifiers reservoir" means, but the concept is wrong. Actually, it's in parallel, not series. Or, "... the attenuation of the power supply toward the amplifier." What the heck does that even mean? Bottom line, you can replace all this verbiage with "Power supply caps should have low ESR and good HF characteristics". Which is why it's a good idea to use better quality electrolytics with film caps in parallel. -- Ron kannan srinivasaraghavan wrote: please read this article on Jensen'( capacitor) website on influence of Filter capacitor on Audio performance.

Not sure I buy it. Curious what frequency is the HF? Is it from the bias circuit at 105KHz? Or the microprocessor 3.088MHz? From my experience with power supplies, bad caps usually causes voltage spikes and drops. In theory caps could cause some oscillation. I have seen this in very rare and I mean rare circumstances. Again shielding plays a much larger role. This group, The whole reason I brought up this subject was from what I have noticed happening on e-bay and audiogon. I know there is a lot of suckers out there but I am not happy with some of the exploiting going on. Outrages claims! What happened to integrity? I certainly did not get into repairing naks to making large amounts of money. I apologize to those who would rather not hear me on a soap box. Vic P.S. those who are interested in some level, azimuth and 3 KHz tapes. Tom Mageras and I are near production. These tapes are FULL track.

Old dry caps have significantly higher ESR, as well as reduced capacitance. IF any power line high frequency stuff gets through the power transformer, a low ESR power supply cap becomes a better AC ground. Likewise any spurrious HF junk induced into or created in digital circuits within Nak is shunted to AC ground "better" with low ESR, or even fresh new caps. My personal view is to give credit to listeners with high resolution stereos when they hear the effects of cap upgrades, but I usually discount the differences (improvement) a bit. Cap changes and upgrades are becomming a staple in vintage audio. I was asked to upgrade capacitors in a Yamaha BX-1 amplifier, which already contained very high quality caps. I can't say that I heard any difference, and the customer reported no differences...but this was far from scientific.

I wonder whether newbies won't find it misleading; let alone, confusing. The subject matter itself is factually correct. In fact. it's old hat. But the presentation and wording border on the incomprehensible. Taken literally, much in the article is wrong. For example. "you cannot utilize that speed if your power supply is too slow to follow rapid signal changes." is simply incorrect. However, it's clear that what he meant to say (but didn't), is "... if the power supply is too slow to avoid following rapid signal changes." Then he says "...the most power amplifiers reservoir is conceptually placed in series with the loudspeaker line " I don't know what "the most power amplifiers reservoir" means, but the concept is wrong. Actually, it's in parallel, not series. Or, "... the attenuation of the power supply toward the amplifier." What the heck does that even mean? Bottom line, you can replace all this verbiage with       "Power supply caps should have low ESR and     good HF characteristics". Which is why it's a good idea to use better quality electrolytics with film caps in parallel. -- Ron kannan srinivasaraghavan wrote: please read this article on Jensen'( capacitor) website on influence of Filter capacitor on Audio performance.

There are so many variables from source material, i.e. studio practices, to listening environment, to humidity in the air that the debate should go on forever! ;o) My wife and I do have fun listening with friends to both CD and LP and occasionally a 2nd Gen copy of reel master tapes. Earlier this summer we had a professional drummer/singer and her husband over listening to music on our Hi End system. Threshold Audio Pre and Power amps driving Wilson Audio WATT/Puppy system with Mark Levinson CD Transport and DAC. She loved the sound of her favorite CDs. Then my wife smiled and told me to spin some vinyl on the Micro Seiki 1500 with a SAEC Tonearm and Talisman Cartridge. (Roughly $8000 for the Digital front end and $4000 for the Vin! > yl system) I put on a standard issue Dire Straits Brothers in Arms album. Our friends jaw hit the floor and she said, "Wow! Now that's how I hear the drum kit!" They came over again recently to listen and she had an album from the jazz music school where she attended in the '70s. I cleaned it up on the Nitty Gritty and put it on. (It was a direct to disc recording!) All of our jaws hit the floor!!! Much fun indeed!!

If you're talking prior to regulation, then yes, storage is increased (capacitors in parallel) much like adding a two fuel tanks to your car. Capacitors in parallel are additive because it increases plate area and reduces ripple. It's been years since I've done power supply work but prior to regulation and larger capacitors are beneficial. After regulation, you want smaller capacitors to keep up slew rate. KA/T is the formula for computing capacitance. K=constant of the dielectric A = surface area of the capacitor, just think of the foil as one area T = the distance between the two plates (foils) So, two capacitors in parallel increase the A (surface area) while two capacitors in series increases T (distance between the foils) and reduces capacitance.

Hats off to you for bringing it to the membership's attention. I have had ESL Labs. service 2 of my decks and Willy Hermann do 3 ( or was it 4 I forget) other decks and these decks reign supreme in my humble Nak stable and they have no special caps( in the power supply unit) in them. In fact neither of these individuals even cared to offer such capacitor upgrades to me ever! I am sure if these were required Jeff Galin would have offered to install these in his total restore of my 680ZX, but he never did. Ditto for Willy. This upgrade option opens up another one of those Pandora's boxes, a la cables and related opinions/views/reality. I guess snake oil can still be sold to the sucker out on ebay and other marketplaces. Nothing wrong if the buyer appreciated the upgrade!

Not sure I buy it. Curious what frequency is the HF? Is it from the bias circuit at 105KHz? Or the microprocessor 3.088MHz? From my experience with power supplies, bad caps usually causes voltage spikes and drops. In theory caps could cause some oscillation. I have seen this in very rare and I mean rare circumstances. Again shielding plays a much larger role.    This group, The whole reason I brought up this subject was from what I have noticed happening on e-bay and audiogon. I know there is a lot of suckers out there but I am not happy with some of the exploiting going on. Outrages claims! What happened to integrity? I certainly did not get into repairing naks to making large amounts of money. I apologize to those who would rather not hear me on a soap box. Vic  P.S. those who are interested in some level, azimuth and 3 KHz tapes. Tom Mageras and I are near production. These tapes are FULL track. We are still experimenting with the results from a Studer A-80QRC and possibly a Dragon. Of course the Speed wow & flutter would be produced from the Studer. It as well as the Dragon have dual direct drive captstans.  -----Original Message----- From: naktalk-bounces at naks.com [mailto:naktalk-bounces at naks.com] On Behalf Of tom brucker Sent: Sunday, September 20, 2009 2:41 PM To: Talk about Nakamichi Cassette Decks Subject: RE: [naktalk] Capacitor talk Vic,    Conventional electrolytics used in Naks have higher ESR, which is a rising impedance with frequency in series with the capacitor, than currently available low ESR caps used in switchmode power supplies. Old dry caps have significantly higher ESR, as well as reduced capacitance. IF any power line high frequency stuff gets through the power transformer, a low ESR power supply cap becomes a better AC ground. Likewise any spurrious HF junk induced into or created in digital circuits within  Nak is shunted to AC ground "better" with low ESR, or even fresh new caps.    My personal view is to give credit to listeners with high resolution stereos when they hear the effects of cap upgrades, but I usually discount the differences (improvement) a bit. Cap changes and upgrades are becomming a staple in vintage audio. I was asked to upgrade capacitors in a Yamaha BX-1 amplifier, which already contained very high quality caps. I can't say that I heard any difference, and the customer reported no differences...but this was far from scientific. I think anyone that can discuss the differences between live recording on a Nak Dragon vs. Otari RtR at 15 ips has my attention when they report what they hear. tom brucker -----Original Message----- From: naktalk-bounces at naks.com [mailto:naktalk-bounces at naks.com]On Behalf Of Victor Gabrenas Sent: Sunday, September 20, 2009 12:53 AM To: 'Talk about Nakamichi Cassette Decks' Subject: RE: [naktalk] Capacitor talk Folks, I am seeing plenty of explanations here but not seeing anything that would support a change in impedance on your power line by replacing caps.

Of course, I wouldn't know because I rarely understand what they are talking about! (Talk to me about market research and as like as not I'll show most people a clean pair of heels - we all have our own specialism and I was once considered by head-hunters to be the most experienced B2B financial 'client-side' researcher in the UK. Not anymore, of course!) But their point is that caps can make a difference to the sound and that may not always be for the better, which is what some have been saying here. Many a restored amp, they tell me, is ruined because traditional caps (oil filled? I don't know!) have been replaced by expensive and popular Blackgates. I imagine that, if what they say IS true, it may also be true of upgrading cassette decks and, therefore, Naks BUT ... .... then we slip into the old chest-nut of 'what is better sound?' Perhaps a cap will change the sound of a Nak, or any bit of kit, to one that is not its original character. But is what we do about restoration to an original state and sound or to "improve" on it? Anyway, what rule is there that defines if such changes make the sound better, or even worse except our own individual set of ears?(Or in my case, singular 3/4 ear!) One may just as well ask if a beef steak tastes better with barbeque, or with mustard, sauce, or if a beef steak tastes better than a pork one. I suppose, in the end, it IS all a matter of .... taste.

Hats off to you for bringing it to the membership's attention. I have had ESL Labs. service 2 of my decks and Willy Hermann do 3 ( or was it 4 I forget) other decks and these decks reign supreme in my humble Nak stable and they have no special caps( in the power supply unit) in them. In fact neither of these individuals even cared to offer such capacitor upgrades to me ever! I am sure if these were required Jeff Galin would have offered to install these in his total restore of my 680ZX, but he never did. Ditto for Willy. This upgrade option opens up another one of those Pandora's boxes, a la cables and related opinions/views/reality. I guess snake oil can still be sold to the sucker out on ebay and other marketplaces. Nothing wrong if the buyer appreciated the upgrade!

Not sure I buy it. Curious what frequency is the HF? Is it from the bias circuit at 105KHz? Or the microprocessor 3.088MHz? From my experience with power supplies, bad caps usually causes voltage spikes and drops. In theory caps could cause some oscillation. I have seen this in very rare and I mean rare circumstances. Again shielding plays a much larger role. This group, The whole reason I brought up this subject was from what I have noticed happening on e-bay and audiogon. I know there is a lot of suckers out there but I am not happy with some of the exploiting going on. Outrages claims! What happened to integrity? I certainly did not get into repairing naks to making large amounts of money. I apologize to those who would rather not hear me on a soap box. Vic P.S. those who are interested in some level, azimuth and 3 KHz tapes. Tom Mageras and I are near production. These tapes are FULL track. We are still experimenting with the results from a Studer A-80QRC and possibly a Dragon. Of course the Speed wow & flutter would be produced from the Studer. It as well as the Dragon have dual direct drive captstans. -----Original Message----- From: naktalk-bounces at naks.com [mailto:naktalk-bounces at naks.com] On Behalf Of tom brucker Sent: Sunday, September 20, 2009 2:41 PM To: Talk about Nakamichi Cassette Decks Subject: RE: [naktalk] Capacitor talk Vic, Conventional electrolytics used in Naks have higher ESR, which is a rising impedance with frequency in series with the capacitor, than currently available low ESR caps used in switchmode power supplies. Old dry caps have significantly higher ESR, as well as reduced capacitance. IF any power line high frequency stuff gets through the power transformer, a low ESR power supply cap becomes a better AC ground. Likewise any spurrious HF junk induced into or created in digital circuits within Nak is shunted to AC ground "better" with low ESR, or even fresh new caps. My personal view is to give credit to listeners with high resolution stereos when they hear the effects of cap upgrades, but I usually discount the differences (improvement) a bit. Cap changes and upgrades are becomming a staple in vintage audio. I was asked to upgrade capacitors in a Yamaha BX-1 amplifier, which already contained very high quality caps. I can't say that I heard any difference, and the customer reported no differences...but this was far from scientific. I think anyone that can discuss the differences between live recording on a Nak Dragon vs. Otari RtR at 15 ips has my attention when they report what they hear. tom brucker -----Original Message----- From: naktalk-bounces at naks.com [mailto:naktalk-bounces at naks.com]On Behalf Of Victor Gabrenas Sent: Sunday, September 20, 2009 12:53 AM To: 'Talk about Nakamichi Cassette Decks' Subject: RE: [naktalk] Capacitor talk Folks, I am seeing plenty of explanations here but not seeing anything that would support a change in impedance on your power line by replacing caps. I agree with replacing caps is a good thing however changing a cap does not change your HF impedance in your DC power supply. No HF in the DC power supply. After reading the article, I noticed it explains switching mode power supplies. Not the same in a Dragon.

Also read Erno Borbley' website for his comments on upgrade for parts kannan https://audio.jensencapacitors.com/public/dokumenter/4pole.pdf ------------------------------ The importance of attenuation and high frequency behaviour No matter how fast the amplifiers signal processing circuits are, you cannot utilize that speed if your power supply is too slow to follow rapid signal changes. The power supply's reservoir capacitor constitutes a vital element in the amplifier chain effecting the signals on the main signal paths as well, because the most power amplifiers reservoir is conceptually placed in series with the loudspeaker line. The main issue is not only that, the capacitor can give you enough charge and quickly enough, but the attenuation of the power supply toward the amplifier. In spite of the fact that the audio band is nominally 20-20 kHz, the stability of the amplifier and the overall sound quality is strongly influenced by reservoir capacitor behaviour at very high frequencies. The function of the reservoir capacitor is not only to store energy, but also filtering, providing decoupling between the power supply and the amplifiers signal processing circuits. For energy storage a conventionally constructed aluminium electrolytic capacitor with sufficient Capacitance (F) x Voltage (V)/ Volume (cm3) ratio and satisfactory low ESR and inductivity at higher frequencies would be suitable. However the capacitors filtering characteristic plays a very important role in decoupling and suppressing unwanted transients and other i.e. digital high frequency noises. --- On Thu, 9/17/09, tom brucker wrote: > From: tom brucker > Subject: RE: [naktalk] Who is ash_win? > To: "Talk about Nakamichi Cassette Decks" > Date: Thursday, September 17, 2009, 9:59 AM > Victor, > I have no affiliation with Kannan other > than to say that he ought to be > familiar with Nakamichi sound. > Power line 'hash' is a popular complaint in California. > Absolute Sound had a > writer who for years commented on powerline issues and went > a long way > towards establishing power line devices as a must-have in > high end systems. > Here in Tennessee, we seem to have too little hash to hear > differences, > however adding extra filtration can't hurt!

Earlier this summer we had a professional drummer/singer and her husband over listening to music on our Hi End system. Threshold Audio Pre and Power amps driving Wilson Audio WATT/Puppy system with Mark Levinson CD Transport and DAC. She loved the sound of her favorite CDs. Then my wife smiled and told me to spin some vinyl on the Micro Seiki 1500 with a SAEC Tonearm and Talisman Cartridge. (Roughly $8000 for the Digital front end and $40 00 for the Vin! yl system) I put on a standard issue Dire Straits Brothers in Arms album. Our friends jaw hit the floor and she said, "Wow! Now that's how I hear the drum kit!" They came over again recently to listen and she had an album from the jazz music school where she attended in the '70s.

My first CD player is a Magnavox CDB-650 which is actually a 16bits machine with 4x over-sampling as well as the well known TDA1541 DAC chip inside. It also has a transport system that has been used in a lot of high-end CD players at that period of time ( late 1980's ). I bought the machine in 1987 at $280 new ( much cheaper than your SONY in 1984. I am performed some components changed ( OP-AMPs and CAPACITORs according to Walt Jung's article in Audio Magazine ). Don't tell me that I am another SUCKER if you know who Walt Jung is. At that time I did an extensive listening on the stock CD player before I perform the mod so I am familar with how it sounds originally. Yes, the difference before and after is very small but the sound is more relax after the mod ( that is just my experience; doesn't represent others ). Well, does it worth the mods, you decide by yourself. The total part cost was $20 at that time. So the total cost of this CD-Player is around $300.                The setup that I have at this moment is a Linn-Sondek LP12 with a AKITO arm and a Sumiko Blue-Point Special, a WADIA 301 CD Player, a Cello Audio Suite, a pair of Marantz-9 power amp and a pair of B&W Matrix 801 Series-II speakers with MIT interconnects and Music Hose speaker cables. I do not need to tell you how much the WADIA costs. I clean all my LPs with a VPI machine before I play. All the components in my setup can be considered to be antiques nowaday and might not consider high-end anymore.                 I compare the same piece of music in different formats. For example, Oscar Peterson Trio's We Get Requests in LP, CD as well as Cassette by Verve ( Cassette is made in Japan ). In general I enjoy the music from the LPs more than that from the CDs ( MOLE ). I don't think I need to tell how the cassette version sounds with my Nak 1000ZXL. At the same time the WADIA is a much better machine than the MAGNAVOX and cost much more. Will I go back to use the MAGNAVOX instead? No, you must be kidding.                 I enjoy listening the CD with my WADIA but when comparing with LP, I still like the sound of LPs at this time. Again I have not compare SACD yet because I never buy any.                 Again this is only my listening experience and do not represent what others will hear with their own setup; with all respect.     Best Regards, Michael                       --- On Tue, 9/22/09, Doug Guth wrote: From: Doug Guth Subject: [naktalk] CD vs Vinyl - A player for the rest of us?

Doug Guth wrote: > Ah yes, the never ending battle between LP and CD. :o)Doug, I don't see it a s battle (not even in jest) but rather, as a trade off. I listen to both, depending on what format I have the specific piece of music I wish to listen to. I suspect many millions others are in the same boat. I am not surprised you were disappointed with the CDP-101. It wasn't too that good as new, of course it's not very good after 25 years (at least). I am surprised at the $1200 you shelled out for it. Compared to the Thorens with SME 3009 and any good cartridge, vinyl has a serious head start in your system. But get, say, an Oppo universal player (pick a model for maybe $400-$500) and you will start to seriously enjoy your CDs -- I am not even talking about SACDs or DVD-As -- at a fraction of the cost of your vinyl PB gear. -- Ron Ah yes, the never ending battle between LP and CD. :o) My own disappointment with a $1200 Sony CDP-101 compared to a Thorens 160/ SME 3009/ Signet Cartridge sparked the creation of the American Audio Labs CD player line back in the '80s. There are so many variables from source material, i.e. studio practices, to listening environment, to humidity in the air that the debate should go on forever! ;o) My wife and I do have fun listening with friends to both CD and LP and occasionally a 2nd Gen copy of reel master tapes. Earlier this summer we had a professional drummer/singer and her husband over listening to music on our Hi End system. Threshold Audio Pre and Power amps driving Wilson Audio WATT/Puppy system with Mark Levinson CD Transport and DAC. She loved the sound of her favorite CDs. Then my wife smiled and told me to spin some vinyl on the Micro Seiki 1500 with a SAEC Tonearm and Talisman Cartridge. (Roughly $8000 for the Digital front end and $40 00 for the Vin! yl system) I put on a standard issue Dire Straits Brothers in Arms album. Our friends jaw hit the floor and she said, "Wow! Now that's how I hear the drum kit!" They came over again recently to listen and she had an album from the jazz music school where she attended in the '70s. I cleaned it up on the Nitty Gritty and put it on. (It was a direct to disc recording!) All of our jaws hit the floor!!! Much fun indeed!!

If you're talking prior to regulation, then yes, storage is increased (capacitors in parallel) much like adding a two fuel tanks to your car. Capacitors in parallel are additive because it increases plate area and reduces ripple. It's been years since I've done power supply work but prior to regulation and larger capacitors are beneficial. After regulation, you want smaller capacitors to keep up slew rate. KA/T is the formula for computing capacitance. K=constant of the dielectric A = surface area of the capacitor, just think of the foil as one area T = the distance between the two plates (foils) So, two capacitors in parallel increase the A (surface area) while two capacitors in series increases T (distance between the foils) and reduces capacitance.

Old dry caps have significantly higher ESR, as well as reduced capacitance. IF any power line high frequency stuff gets through the power transformer, a low ESR power supply cap becomes a better AC ground. Likewise any spurrious HF junk induced into or created in digital circuits within Nak is shunted to AC ground "better" with low ESR, or even fresh new caps. My personal view is to give credit to listeners with high resolution stereos when they hear the effects of cap upgrades, but I usually discount the differences (improvement) a bit. Cap changes and upgrades are becomming a staple in vintage audio. I was asked to upgrade capacitors in a Yamaha BX-1 amplifier, which already contained very high quality caps. I can't say that I heard any difference, and the customer reported no differences...but this was far from scientific. I think anyone that can discuss the differences between live recording on a Nak Dragon vs. Otari RtR at 15 ips has my attention when they report what they hear. tom brucker -----Original Message----- From: naktalk-bounces at naks.com [mailto:naktalk-bounces at naks.com]On Behalf Of Victor Gabrenas Sent: Sunday, September 20, 2009 12:53 AM To: 'Talk about Nakamichi Cassette Decks' Subject: RE: [naktalk] Capacitor talk Folks, I am seeing plenty of explanations here but not seeing anything that would support a change in impedance on your power line by replacing caps. I agree with replacing caps is a good thing however changing a cap does not change your HF impedance in your DC power supply. No HF in the DC power supply.

Also read Erno Borbley' website for his comments on upgrade for parts kannan https://audio.jensencapacitors.com/public/dokumenter/4pole.pdf ------------------------------ The importance of attenuation and high frequency behaviour No matter how fast the amplifiers signal processing circuits are, you cannot utilize that speed if your power supply is too slow to follow rapid signal changes. The power supply's reservoir capacitor constitutes a vital element in the amplifier chain effecting the signals on the main signal paths as well, because the most power amplifiers reservoir is conceptually placed in series with the loudspeaker line. The main issue is not only that, the capacitor can give you enough charge and quickly enough, but the attenuation of the power supply toward the amplifier. In spite of the fact that the audio band is nominally 20-20 kHz, the stability of the amplifier and the overall sound quality is strongly influenced by reservoir capacitor behaviour at very high frequencies. The function of the reservoir capacitor is not only to store energy, but also filtering, providing decoupling between the power supply and the amplifiers signal processing circuits. For energy storage a conventionally constructed aluminium electrolytic capacitor with sufficient Capacitance (F) x Voltage (V)/ Volume (cm3) ratio and satisfactory low ESR and inductivity at higher frequencies would be suitable. However the capacitors filtering characteristic plays a very important role in decoupling and suppressing unwanted transients and other i.e. digital high frequency noises. --- On Thu, 9/17/09, tom brucker wrote: > From: tom brucker > Subject: RE: [naktalk] Who is ash_win? > To: "Talk about Nakamichi Cassette Decks" > Date: Thursday, September 17, 2009, 9:59 AM > Victor, > I have no affiliation with Kannan other > than to say that he ought to be > familiar with Nakamichi sound. > Power line 'hash' is a popular complaint in California. > Absolute Sound had a > writer who for years commented on powerline issues and went > a long way > towards establishing power line devices as a must-have in > high end systems. > Here in Tennessee, we seem to have too little hash to hear > differences, > however adding extra filtration can't hurt!

The single most limiting factor I have seen is source related. VTA (and the right amount of tone-arm damping) will reveal a wide soundstage and correct placement of instruments. The ZXL is capable of reproducing the incredible width and depth of the venue and even gives you a sense of dimensions to instruments like pianos. With the 68x series and ZXL series decks, even very low frequency artifacts caused by record warps are reproduced!

To: "Talk about Nakamichi Cassette Decks" Date: Tuesday, September 22, 2009, 10:02 PM Hi Doug:              I guess I have a same kind of experience dealing with CD players as well. My first CD player is a Magnavox CDB-650 which is actually a 16bits machine with 4x over-sampling as well as the well known TDA1541 DAC chip inside. It also has a transport system that has been used in a lot of high-end CD players at that period of time ( late 1980's ). I bought the machine in 1987 at $280 new ( much cheaper than your SONY in 1984. I am performed some components changed ( OP-AMPs and CAPACITORs according to Walt Jung's article in Audio Magazine ). Don't tell me that I am another SUCKER if you know who Walt Jung is. At that time I did an extensive listening on the stock CD player before I perform the mod so I am familar with how it sounds originally. Yes, the difference before and after is very small but the sound is more relax after the mod ( that is just my experience; doesn't represent others ). Well, does it worth the mods, you decide by yourself. The total part cost was $20 at that time. So the total cost of this CD-Player is around $300.                The setup that I have at this moment is a Linn-Sondek LP12 with a AKITO arm and a Sumiko Blue-Point Special, a WADIA 301 CD Player, a Cello Audio Suite, a pair of Marantz-9 power amp and a pair of B&W Matrix 801 Series-II speakers with MIT interconnects and Music Hose speaker cables. I do not need to tell you how much the WADIA costs. I clean all my LPs with a VPI machine before I play. All the components in my setup can be considered to be antiques nowaday and might not consider high-end anymore.                 I compare the same piece of music in different formats. For example, Oscar Peterson Trio's We Get Requests in LP, CD as well as Cassette by Verve ( Cassette is made in Japan ). In general I enjoy the music from the LPs more than that from the CDs ( MOLE ). I don't think I need to tell how the cassette version sounds with my Nak 1000ZXL. At the same time the WADIA is a much better machine than the MAGNAVOX and cost much more. Will I go back to use the MAGNAVOX instead? No, you must be kidding.                 I enjoy listening the CD with my WADIA but when comparing with LP, I still like the sound of LPs at this time. Again I have not compare SACD yet because I never buy any.                 Again this is only my listening experience and do not represent what others will hear with their own setup; with all respect.     Best Regards, Michael                       --- On Tue, 9/22/09, Doug Guth wrote: From: Doug Guth Subject: [naktalk] CD vs Vinyl - A player for the rest of us?

There are so many variables from source material, i.e. studio practices, to listening environment, to humidity in the air that the debate should go on forever! ;o) My wife and I do have fun listening with friends to both CD and LP and occasionally a 2nd Gen copy of reel master tapes. Earlier this summer we had a professional drummer/singer and her husband over listening to music on our Hi End system. Threshold Audio Pre and Power amps driving Wilson Audio WATT/Puppy system with Mark Levinson CD Transport and DAC. She loved the sound of her favorite CDs. Then my wife smiled and told me to spin some vinyl on the Micro Seiki 1500 with a SAEC Tonearm and Talisman Cartridge. (Roughly $8000 for the Digital front end and $40 00 for the Vin! yl system) I put on a standard issue Dire Straits Brothers in Arms album. Our friends jaw hit the floor and she said, "Wow! Now that's how I hear the drum kit!" They came over again recently to listen and she had an album from the jazz music school where she attended in the '70s. I cleaned it up on the Nitty Gritty and put it on. (It was a direct to disc recording!) All of our jaws hit the floor!!! Much fun indeed!! I'm not anti CD, I just realize that there is a lot of wonderful music to be had by dragging a rock through those black vinyl grooves!

Actually, on purely technical grounds, CDs are based on a far better technology that LPs. However, the two formats have features that are not necessarily better or worse, just different. Digital audio is far more complex, so sonic quality (of either a specific recording or a specific piece of equipment) is more dependent on implementation. Because digital technology is so involved, certain parts of CD players (mostly, the DAC and LPF) must be of high quality.Yet, again and again, I see people comparing a $5,000 record playing gear (turntable plus cartridge plus phono stage) with a $100 CD player and then conclude that CD technology is inferiour. In my view, in comparing apples to apples (best quality recordings played on similarly priced equipment), CDs are superiour. YMMV. -- Ron RSB wrote: Its always nice to have a discussion on the merits of digital vs analog, especially from such well informed and experianced audiophiles. My two centavos - I have not much cared for CDs, good engineering or not, except for background music or other non-involved in front of the speakers listening. I have had several CD players over the years - from the early Marantz to Kenwood 1 bit to others. Since I developed a fairly large collection, I was happy to find what is probably the most easy to listen to CD player out there. This was an unexpected surprise, given the original purpose of the Sony design - this is the Sony Playstation 1 and can be had for anywhere on ebay from $20 on up. It's no joke, this is one of the best players out there. I have purchased several for use and for parts, you have to be careful about the condition tho and may have to do a little cleaning and tweaking of the Pots to get them to play right, but when you get it all together the sound is amazing. For my tastes anyway, I hear a much more full middle and very little of the "electronica" that has dogged most of the CD sound vs good analogue sources. If you go hunting for this, and it's cheap to check it our for yourself, you have to get the Playstation 1 Model SCHP-1001, check for the model specifically as it has the great RCA Jack setup used only on the early models, these units had the great chipset- MIPS R3000A-family R3051. Some may have problems with non commercial CDs, but the ones I have cleaned up work well on almost all of my home burned CDs. My vinyl source is from a Music Hall 5.1 TT with Shure V15MVR cartridge, ADCOM 565 preamp, which has a real good phono stage. I have a VPI record cleaning machine which is a must have (or equivalent) which is use regularly. This is still my main musical source for critical listening, but when its CDs, I go to the ex-video gamer device every time. My old CD players are boxed up and are no longer used. So, for those that gave up on CD players because of harshness and lack of subtle detail, this is a good alternative.

The deck works very well however the right indicator is at 30 db as opposed to 40 like the left shows. In other words when I turn the power on one indicator shows 40 the other 30 db. I generally set my record level to the left indicator but when I do the record calibration I set both needles to 0 db with the 400 hz built in tone generator. So with that my record calibration is probably out of whack. Same for bias. Can that indicator be adjusted? And if yes, how?

In Physics, capacitors have one -- and only one -- attribute; that is, capacitance. Actual, real life capacitors have additional, parasitic attributes, such as resistance -- both series (ESR) and parallel (leakage) -- and inductance (not to mention losses, memory etc.). As you know, there are many capacitor types, each lending itself to different cap characteristics, such as those parasitic attributes, in addition to capacitance values and working voltage. Design engineers calculate what 'pure' cap is needed and then select the cap type that best serves that specific application.. This is then followed by calculating how the real-world cap will actually perform in that circuit., Second-guessing the design engineer by 'upgrading' caps can be counterproductive. For example, it would seem to the initiated that increasing filter capacitor values in power supplies is goodness, but he may not be aware that this also increases AC current (both inrush and steady state), that over time, can harm the rectifiers, power transformer and even the new caps themselves. Hobbyists that swear by 'recapping' are often oblivious to the various considerations involved in replacement cap choices. There is one case where this is not true. That is, when cost was one of the engineer's important considerations. Had he not been constrained by this consideration and if performance or product longevity were high on his list, his choice might have been different. When a hobbyist takes that cost out of the equation while stressing performance, he may arrive at a different choice -- assuming he or she are technically capable of making the assessment. Bottom line: before replacing capacitor types or values in a circuit, one should be sure that all ramifications are fully understood . -- Ron Graham A Nelson wrote: A few associates and a friend of mine with a professional interest in tube amps and restoration, have told me the choice of caps is critical to each circuit design. Of course, I wouldn’t know because I rarely understand what they are talking about! (Talk to me about market research and as like as not I’ll show most people a clean pair of heels – we all have our own specialism and I was once considered by head-hunters to be the most experienced B2B financial ‘client-side’ researcher in the UK. Not anymore, of course!) But their point is that caps can make a difference to the sound and that may not always be for the better, which is what some have been saying here. Many a restored amp, they tell me, is ruined because traditional caps (oil filled? I don’t know!) have been replaced by expensive and popular Blackgates. I imagine that, if what they say IS true, it may also be true of upgrading cassette decks and, therefore, Naks BUT ... .... then we slip into the old chest-nut of ‘what is better sound?’ Perhaps a cap will change the sound of a Nak, or any bit of kit, to one that is not its original character. But is what we do about restoration to an original state and sound or to “improve” on it? Anyway, what rule is there that defines if such changes make the sound better, or even worse except our own individual set of ears?(Or in my case, singular 3/4 ear!) One may just as well ask if a beef steak tastes better with barbeque, or with mustard, sauce, or if a beef steak tastes better than a pork one. I suppose, in the end, it IS all a matter of .... taste.

Hats off to you for bringing it to the membership's attention. I have had ESL Labs. service 2 of my decks and Willy Hermann do 3 ( or was it 4 I forget) other decks and these decks reign supreme in my humble Nak stable and they have no special caps( in the power supply unit) in them. In fact neither of these individuals even cared to offer such capacitor upgrades to me ever! I am sure if these were required Jeff Galin would have offered to install these in his total restore of my 680ZX, but he never did. Ditto for Willy.

From my experience with power supplies, bad caps usually causes voltage spikes and drops. In theory caps could cause some oscillation. I have seen this in very rare and I mean rare circumstances. Again shielding plays a much larger role. This group, The whole reason I brought up this subject was from what I have noticed happening on e-bay and audiogon.

Old dry caps have significantly higher ESR, as well as reduced capacitance. IF any power line high frequency stuff gets through the power transformer, a low ESR power supply cap becomes a better AC ground. Likewise any spurrious HF junk induced into or created in digital circuits within Nak is shunted to AC ground "better" with low ESR, or even fresh new caps. My personal view is to give credit to listeners with high resolution stereos when they hear the effects of cap upgrades, but I usually discount the differences (improvement) a bit. Cap changes and upgrades are becomming a staple in vintage audio. I was asked to upgrade capacitors in a Yamaha BX-1 amplifier, which already contained very high quality caps. I can't say that I heard any difference, and the customer reported no differences...but this was far from scientific. I think anyone that can discuss the differences between live recording on a Nak Dragon vs. Otari RtR at 15 ips has my attention when they report what they hear. tom brucker -----Original Message----- From: naktalk-bounces at naks.com [mailto:naktalk-bounces at naks.com]On Behalf Of Victor Gabrenas Sent: Sunday, September 20, 2009 12:53 AM To: 'Talk about Nakamichi Cassette Decks' Subject: RE: [naktalk] Capacitor talk Folks, I am seeing plenty of explanations here but not seeing anything that would support a change in impedance on your power line by replacing caps. I agree with replacing caps is a good thing however changing a cap does not change your HF impedance in your DC power supply. No HF in the DC power supply.

Also read Erno Borbley' website for his comments on upgrade for parts kannan https://audio.jensencapacitors.com/public/dokumenter/4pole.pdf ------------------------------ The importance of attenuation and high frequency behaviour No matter how fast the amplifiers signal processing circuits are, you cannot utilize that speed if your power supply is too slow to follow rapid signal changes. The power supply's reservoir capacitor constitutes a vital element in the amplifier chain effecting the signals on the main signal paths as well, because the most power amplifiers reservoir is conceptually placed in series with the loudspeaker line. The main issue is not only that, the capacitor can give you enough charge and quickly enough, but the attenuation of the power supply toward the amplifier. In spite of the fact that the audio band is nominally 20-20 kHz, the stability of the amplifier and the overall sound quality is strongly influenced by reservoir capacitor behaviour at very high frequencies. The function of the reservoir capacitor is not only to store energy, but also filtering, providing decoupling between the power supply and the amplifiers signal processing circuits. For energy storage a conventionally constructed aluminium electrolytic capacitor with sufficient Capacitance (F) x Voltage (V)/ Volume (cm3) ratio and satisfactory low ESR and inductivity at higher frequencies would be suitable. However the capacitors filtering characteristic plays a very important role in decoupling and suppressing unwanted transients and other i.e. digital high frequency noises. --- On Thu, 9/17/09, tom brucker wrote: > From: tom brucker > Subject: RE: [naktalk] Who is ash_win? > To: "Talk about Nakamichi Cassette Decks" > Date: Thursday, September 17, 2009, 9:59 AM > Victor, > I have no affiliation with Kannan other > than to say that he ought to be > familiar with Nakamichi sound. > Power line 'hash' is a popular complaint in California. > Absolute Sound had a > writer who for years commented on powerline issues and went > a long way > towards establishing power line devices as a must-have in > high end systems. > Here in Tennessee, we seem to have too little hash to hear > differences, > however adding extra filtration can't hurt!

Hi Doug: I guess I have a same kind of experience dealing with CD players as well. My first CD player is a Magnavox CDB-650 which is actually a 16bits machine with 4x over-sampling as well as the well known TDA1541 DAC chip inside. It also has a transport system that has been used in a lot of high-end CD players at that period of time ( late 1980's ). I bought the machine in 1987 at $280 new ( much cheaper than your SONY in 1984. I am performed some components changed ( OP-AMPs and CAPACITORs according to Walt Jung's article in Audio Magazine ). Don't tell me that I am another SUCKER if you know who Walt Jung is. At that time I did an extensive listening on the stock CD player before I perform the mod so I am familar with how it sounds originally. Yes, the difference before and after is very small but the sound is more relax after the mod ( that is just my experience; doesn't represent others ). Well, does it worth the mods, you decide by yourself. The total part cost was $20 at that time. So the total cost of this CD-Player is around $300. The setup that I have at this moment is a Linn-Sondek LP12 with a AKITO arm and a Sumiko Blue-Point Special, a WADIA 301 CD Player, a Cello Audio Suite, a pair of Marantz-9 power amp and a pair of B&W Matrix 801 Series-II speakers with MIT interconnects and Music Hose speaker cables. I do not need to tell you how much the WADIA costs. I clean all my LPs with a VPI machine before I play. All the components in my setup can be considered to be antiques nowaday and might not consider high-end anymore. I compare the same piece of music in different formats. For example, Oscar Peterson Trio's We Get Requests in LP, CD as well as Cassette by Verve ( Cassette is made in Japan ). In general I enjoy the music from the LPs more than that from the CDs ( MOLE ). I don't think I need to tell how the cassette version sounds with my Nak 1000ZXL. At the same time the WADIA is a much better machine than the MAGNAVOX and cost much more. Will I go back to use the MAGNAVOX instead? No, you must be kidding. I enjoy listening the CD with my WADIA but when comparing with LP, I still like the sound of LPs at this time. Again I have not compare SACD yet because I never buy any. Again this is only my listening experience and do not represent what others will hear with their own setup; with all respect.

There are so many variables from source material, i.e. studio practices, to listening environment, to humidity in the air that the debate should go on forever! ;o) My wife and I do have fun listening with friends to both CD and LP and occasionally a 2nd Gen copy of reel master tapes. Earlier this summer we had a professional drummer/singer and her husband over listening to music on our Hi End system. Threshold Audio Pre and Power amps driving Wilson Audio WATT/Puppy system with Mark Levinson CD Transport and DAC. She loved the sound of her favorite CDs. Then my wife smiled and told me to spin some vinyl on the Micro Seiki 1500 with a SAEC Tonearm and Talisman Cartridge. (Roughly $8000 for the Digital front end and $40 00 for the Vin! yl system) I put on a standard issue Dire Straits Brothers in Arms album. Our friends jaw hit the floor and she said, "Wow! Now that's how I hear the drum kit!" They came over again recently to listen and she had an album from the jazz music school where she attended in the '70s. I cleaned it up on the Nitty Gritty and put it on. (It was a direct to disc recording!) All of our jaws hit the floor!!! Much fun indeed!!

Actually, on purely technical grounds, CDs are based on a far better technology that LPs. However, the two formats have features that are not necessarily better or worse, just different. Digital audio is far more complex, so sonic quality (of either a specific recording or a specific piece of equipment) is more dependent on implementation. Because digital technology is so involved, certain parts of CD players (mostly, the DAC and LPF) must be of high quality.Yet, again and again, I see people comparing a $5,000 record playing gear (turntable plus cartridge plus phono stage) with a $100 CD player and then conclude that CD technology is inferiour. In my view, in comparing apples to apples (best quality recordings played on similarly priced equipment), CDs are superiour. YMMV. -- Ron RSB wrote: Its always nice to have a discussion on the merits of digital vs analog, especially from such well informed and experianced audiophiles. My two centavos - I have not much cared for CDs, good engineering or not, except for background music or other non-involved in front of the speakers listening. I have had several CD players over the years - from the early Marantz to Kenwood 1 bit to others. Since I developed a fairly large collection, I was happy to find what is probably the most easy to listen to CD player out there. This was an unexpected surprise, given the original purpose of the Sony design - this is the Sony Playstation 1 and can be had for anywhere on ebay from $20 on up. It's no joke, this is one of the best players out there. I have purchased several for use and for parts, you have to be careful about the condition tho and may have to do a little cleaning and tweaking of the Pots to get them to play right, but when you get it all together the sound is amazing. For my tastes anyway, I hear a much more full middle and very little of the "electronica" that has dogged most of the CD sound vs good analogue sources. If you go hunting for this, and it's cheap to check it our for yourself, you have to get the Playstation 1 Model SCHP-1001, check for the model specifically as it has the great RCA Jack setup used only on the early models, these units had the great chipset- MIPS R3000A-family R3051. Some may have problems with non commercial CDs, but the ones I have cleaned up work well on almost all of my home burned CDs. My vinyl source is from a Music Hall 5.1 TT with Shure V15MVR cartridge, ADCOM 565 preamp, which has a real good phono stage. I have a VPI record cleaning machine which is a must have (or equivalent) which is use regularly. This is still my main musical source for critical listening, but when its CDs, I go to the ex-video gamer device every time. My old CD players are boxed up and are no longer used. So, for those that gave up on CD players because of harshness and lack of subtle detail, this is a good alternative.

This could mean that my record and bias calibrations are out as I set both indicators at 0 db. When I record a 400hz signal at 0 db on both channels and I play it back on another deck the right channel is stronger. Can this be adjusted and if yes how?

However, before you even touch those, better make sure that the meter adjustment is actually incorrect and that the wrong indication is not due to circuitry preceding the meter. To do that you need (at least) an AC VTVM or DMM (ideally, also an audio generator and 'scope), which you will also need to make the adjustment, once you verify that everything else is in order. Needless to say, you will also need the service manual, that you can download from the Naks wiki page.

But if I want to pick and choose songs to tape, there will be, almost every tape, some distortion (tape equivalent of lp stylus being jarred in groove, flutter perhaps?)

However, before you even touch those, better make sure that the meter adjustment is actually incorrect and that the wrong indication is not due to circuitry preceding the meter. To do that you need (at least) an AC VTVM or DMM (ideally, also an audio generator and 'scope), which you will also need to make the adjustment, once you verify that everything else is in order. Needless to say, you will also need the service manual, that you can download from the Naks wiki page. Good luck, -- Ron Peter Tanner wrote: Hi Ron It's not about capacitors but about my 582 you helped me with sometime ago. The deck works very well however the right indicator is at 30 db as opposed to 40 like the left shows. In other words when I turn the power on one indicator shows 40 the other 30 db. I generally set my record level to the left indicator but when I do the record calibration I set both needles to 0 db with the 400 hz built in tone generator. So with that my record calibration is probably out of whack. Same for bias. Can that indicator be adjusted? And if yes, how?

In Physics, capacitors have one -- and only one -- attribute; that is, capacitance. Actual, real life capacitors have additional, parasitic attributes, such as resistance -- both series (ESR) and parallel (leakage) -- and inductance (not to mention losses, memory etc.). As you know, there are many capacitor types, each lending itself to different cap characteristics, such as those parasitic attributes, in addition to capacitance values and working voltage. Design engineers calculate what 'pure' cap is needed and then select the cap type that best serves that specific application.. This is then followed by calculating how the real-world cap will actually perform in that circuit., Second-guessing the design engineer by 'upgrading' caps can be counterproductive. For example, it would seem to the initiated that increasing filter capacitor values in power supplies is goodness, but he may not be aware that this also increases AC current (both inrush and steady state), that over time, can harm the rectifiers, power transformer and even the new caps themselves. Hobbyists that swear by 'recapping' are often oblivious to the various considerations involved in replacement cap choices. There is one case where this is not true. That is, when cost was one of the engineer's important considerations. Had he not been constrained by this consideration and if performance or product longevity were high on his list, his choice might have been different. When a hobbyist takes that cost out of the equation while stressing performance, he may arrive at a different choice -- assuming he or she are technically capable of making the assessment. Bottom line: before replacing capacitor types or values in a circuit, one should be sure that all ramifications are fully understood . -- Ron Graham A Nelson wrote: A few associates and a friend of mine with a professional interest in tube amps and restoration, have told me the choice of caps is critical to each circuit design. Of course, I wouldn’t know because I rarely understand what they are talking about! (Talk to me about market research and as like as not I’ll show most people a clean pair of heels – we all have our own specialism and I was once considered by head-hunters to be the most experienced B2B financial ‘client-side’ researcher in the UK. Not anymore, of course!) But their point is that caps can make a difference to the sound and that may not always be for the better, which is what some have been saying here. Many a restored amp, they tell me, is ruined because traditional caps (oil filled? I don’t know!) have been replaced by expensive and popular Blackgates. I imagine that, if what they say IS true, it may also be true of upgrading cassette decks and, therefore, Naks BUT ... .... then we slip into the old chest-nut of ‘what is better sound?’ Perhaps a cap will change the sound of a Nak, or any bit of kit, to one that is not its original character. But is what we do about restoration to an original state and sound or to “improve” on it? Anyway, what rule is there that defines if such changes make the sound better, or even worse except our own individual set of ears?(Or in my case, singular 3/4 ear!) One may just as well ask if a beef steak tastes better with barbeque, or with mustard, sauce, or if a beef steak tastes better than a pork one. I suppose, in the end, it IS all a matter of .... taste.

I have had ESL Labs. service 2 of my decks and Willy Hermann do 3 ( or was it 4 I forget) other decks and these decks reign supreme in my humble Nak stable and they have no special caps( in the power supply unit) in them. In fact neither of these individuals even cared to offer such capacitor upgrades to me ever! I am sure if these were required Jeff Galin would have offered to install these in his total restore of my 680ZX, but he never did. Ditto for Willy.

Not sure I buy it. Curious what frequency is the HF? Is it from the bias circuit at 105KHz? Or the microprocessor 3.088MHz? From my experience with power supplies, bad caps usually causes voltage spikes and drops. In theory caps could cause some oscillation. I have seen this in very rare and I mean rare circumstances. Again shielding plays a much larger role. This group, The whole reason I brought up this subject was from what I have noticed happening on e-bay and audiogon.

Old dry caps have significantly higher ESR, as well as reduced capacitance. IF any power line high frequency stuff gets through the power transformer, a low ESR power supply cap becomes a better AC ground. Likewise any spurrious HF junk induced into or created in digital circuits within Nak is shunted to AC ground "better" with low ESR, or even fresh new caps. My personal view is to give credit to listeners with high resolution stereos when they hear the effects of cap upgrades, but I usually discount the differences (improvement) a bit. Cap changes and upgrades are becomming a staple in vintage audio. I was asked to upgrade capacitors in a Yamaha BX-1 amplifier, which already contained very high quality caps. I can't say that I heard any difference, and the customer reported no differences...but this was far from scientific. I think anyone that can discuss the differences between live recording on a Nak Dragon vs. Otari RtR at 15 ips has my attention when they report what they hear. tom brucker -----Original Message----- From: naktalk-bounces at naks.com [mailto:naktalk-bounces at naks.com]On Behalf Of Victor Gabrenas Sent: Sunday, September 20, 2009 12:53 AM To: 'Talk about Nakamichi Cassette Decks' Subject: RE: [naktalk] Capacitor talk Folks, I am seeing plenty of explanations here but not seeing anything that would support a change in impedance on your power line by replacing caps. I agree with replacing caps is a good thing however changing a cap does not change your HF impedance in your DC power supply. No HF in the DC power supply.

Also read Erno Borbley' website for his comments on upgrade for parts kannan https://audio.jensencapacitors.com/public/dokumenter/4pole.pdf ------------------------------ The importance of attenuation and high frequency behaviour No matter how fast the amplifiers signal processing circuits are, you cannot utilize that speed if your power supply is too slow to follow rapid signal changes. The power supply's reservoir capacitor constitutes a vital element in the amplifier chain effecting the signals on the main signal paths as well, because the most power amplifiers reservoir is conceptually placed in series with the loudspeaker line. The main issue is not only that, the capacitor can give you enough charge and quickly enough, but the attenuation of the power supply toward the amplifier. In spite of the fact that the audio band is nominally 20-20 kHz, the stability of the amplifier and the overall sound quality is strongly influenced by reservoir capacitor behaviour at very high frequencies. The function of the reservoir capacitor is not only to store energy, but also filtering, providing decoupling between the power supply and the amplifiers signal processing circuits. For energy storage a conventionally constructed aluminium electrolytic capacitor with sufficient Capacitance (F) x Voltage (V)/ Volume (cm3) ratio and satisfactory low ESR and inductivity at higher frequencies would be suitable. However the capacitors filtering characteristic plays a very important role in decoupling and suppressing unwanted transients and other i.e. digital high frequency noises. --- On Thu, 9/17/09, tom brucker wrote: > From: tom brucker > Subject: RE: [naktalk] Who is ash_win? > To: "Talk about Nakamichi Cassette Decks" > Date: Thursday, September 17, 2009, 9:59 AM > Victor, > I have no affiliation with Kannan other > than to say that he ought to be > familiar with Nakamichi sound. > Power line 'hash' is a popular complaint in California. > Absolute Sound had a > writer who for years commented on powerline issues and went > a long way > towards establishing power line devices as a must-have in > high end systems. > Here in Tennessee, we seem to have too little hash to hear > differences, > however adding extra filtration can't hurt!

Doug's experience is mine exactly - I'm a drummer and would be guitarist and I have both vinyl and Cd versions of Dire Straits (which to my ears - or pressing are NOT in the pantheon of great recordings). Try any Paul Simon album or Cat Stevens. I had a Thorens TD 160, standard arm and Shure V15 II which I collected from a tip for £2. I have 5 CD players, Technics, Rotel 865BX LE (£450 in 1991) Nad BE something (£200 in 2006), Marantz 63SE KI signature ( mid 1990's £500) and a Docet Lector 5T (£1250 in 2003). The Lector has had two capacitor upgrades and has Telefunken valves in it. Its very, very good with real vinyl like qualities of a sense of space as well as detail. I have listed the CD players in order of increasing sound quality. The TD160 beats all the CD players for stage width and depth, bass and punch without that searing gritty treble I associate with CD. Only the Marantz and Lector come near. I sold the deck on Ebay for £150 and the V15 for £60. So my real terms record deck at £210 looks a steal. Its currently worth about the same as the Marantz, still an excellent machine by the way but can't compete with the TD160. One vital ingredient here, however, is how you mount your record player. If you put in on a coffee table or close to speaker vibration, forget it. As long as you can isolate your LPs from vibration ideally on a separate wall mounted shelf and set up the deck right with a new belt, I feel most agree that vinyl wins, and for peanuts. What's more, the TD160 will still be going when all these CD players are dead. A few years ago Linn set up their best LP12 (£5,000) against their CD12 (£12,000) at a Hi Fi exhibition - over 70% of listeners preferred vinyl.

I have undertaken the daunting task of reviving my LX-3 2 head Nak back to life. It has essentially been in a dormant state for the last 15 years or so and it has given me almost as many years of faithful service. When I dropped in a cassette tape and pressed the PLAY button, it was no surprise to find that it played rather fast with a rather distorted output. This being the first time I have dared to open my venerated NAK, can anyone provide me some pointers as to where to I should start before embarking on repairing this device. I must point out that, with the aid of the LX-3 service manual, I and have carefully exposed the drive mechanism. The tape drive mechanism seems to be fairly clean and the belts seem to be OK, at least to my untrained eye. I suspect that the rubber rollers may have dried out a somewhat over the years and that that the tape is slipping. Any suggestions or help would be welcome.

Probably the cause of the speed is that the pinch rollers are not pivoting up to contact the capstan shafts. The lubricant that Nakamichi used on the shafts of the pinch roller rocker arms hardens with age and lack of use. Unfortunately, freeing the rockers means that you have to change the position of the tape guides. You need to be able to get the guides back to exactly the same height as they are now to be able to recalibrate the machine once reassembled. Others have given ideas on careful measurement before disassembly. I am in process of having an alignment jig remanufactured but am still a month or so away from completion. Best of luck.
