In transferring tapes made on inexpensive machines (like many well-meaning oral-history projects), I have seen many tapes with azimuth errors outside of the automatic correction range of the Dragon. I generally manually adjust an MR-1, or if the tape is otherwise superb, manually adjust a Dragon and then readjust it afterwards to have proper azimuth in the centre. The NM demo was taken from the centre channel of a DVD while the JD demo was taken from a CD. Any HF source will permit proper azimuth adjustment. White noise may be the easiest to use as there are no false peaks. Any tone can provide a false peak, so with tones, it's best to check at two frequencies and if they are not even multiples of each other, all the better.

So I had a chance to look at little closer at this circuit and what the measurement is that is being referred to.  The schematic doesn't show TP102, 202, but looking at the board layout, I realized that these test points are actually measuring the record head current across a 100ohm resistor, so meter impedance is definitely not a factor.  The record EQ amp is part of the final output stage of the Dolby chip and is supposed to compensate high frequencies with a resonance point at 21khz.  The measurement is made with the bias oscillator off, hence the open bias cut jumper, so only the 21khz sine wave is seen. When I think of a resonance point, I expect to see a point where the amplitude is maximized, and falls off on both sides of the adjustment.  So maybe something is wrong with the EQ amplifier in my case.  I believe the deck to be fully functional and have recorded with it before, but if the very high end is off, these old ears might not have been able to hear it.  In self-conducted hearing tests, just under 15k is about the very highest I can still hear, and that's pretty good for late 50s. Someone please check my logic on this.  What kind of signal level SHOULD I expect to see when tweaking this circuit?  Is my input level too low?  I assumed when the manual said 21khz -20db, that it meant -20dbV which is around 283mv P-P going into the jacks.  I am seeing 3.5 mv across the 100ohm resistor and there is no amplitude peak, only goes slightly higher when the L104, 204 core is backed out all the way. Thanks for any help,  great to have you guys to consult with.

Sorry for the late response, Google often places Nak list's posts into spam folder... Regarding your question. If you get correct W&F with old parts, I can't suggest anything better than to use the best parts available. Pinch rollers in Naks, AFAIK, doesn't need replacement, maybe, only "tuning" like shaving off very thin surface rubber layer with some rubber refurbish liquid (be careful to not to touch anything else with this liquid if you'll decide to use it). It's a summary opinion at tapeheads.net. But, I think, rollers may be just cleaned with isopropyl intensively and used as is. Be careful with new rollers. They may be of very low quality, even if they look good, they can not only reduce the sound quality, but even be incompatible with some sensitive mechas (in double capstan decks, the tape may be "chewed" if using improper rollers, especially the left one; for this sensitive types of mechas only high quality rollers must be used, some experts consider even Black Reel rollers are not enough for such machines so you may need a kind of fantastic parts for audiophile level if you use new ones). Good belts for Naks and other decks may be obtained from Marrs Communication if they work now. Some years ago these belts considered the best available. I use different belts: in some decks there are originals, in others - very basic new belts, but I also ordered spare Marrs belts for the couple of decks. I'm not an audiophile so I likely will not hear the difference even if the belt is not ideal, my main target is reliability while at acceptable quality level. 2018-12-27 1:40 GMT+03:00, Tom Wiedmann via Naktalk : > Thank you for the responses, Andrew and Fran.  So where do most of you get > your pinch rollers?  I have tried several different sources.  They don't > seem too different from one another, but they do perform worse than the ones > that were in the machine to begin with.  I replaced all the rubber on this > machine because I wanted to start with fresh parts.  The rollers that were > in the machine were moderately worn but not that bad.  They were not cracked > or gummy, just grooved a bit.  Replacing them with new seemed to degrade the > W&F the most.  I used a PRB belt and that made a little bit of negative > difference, just measurable, when compared to the old.  I measured .04 > weighted RMS / .07 peak before my 'upgrade' and am now at 0.06 RMS / .12, > right at or over the Nak spec limit with all parts replaced with new.  Seems > I should have just left well enough alone, but it seemed directionally > correct to replace all rubber parts.  I have a pretty decent ear, and I > believe I can actually hear that difference in music played over the > machine.  Should I just go on using the old parts?  I would prefer to start > with new parts, so they will last, because I plan to pass this deck on to > someone else, but not if it means that much worse performance. > Thank you all for your help.  This is a great forum, and I love that there > is such a community dedicated to these machines that we love. > Tom > > Message: 3 > Date: Wed, 26 Dec 2018 08:53:26 +0300 > From: Andrew via Naktalk > To: Tom Wiedmann ,  Talk about Nakamichi >     Cassette Decks > Subject: Re: [naktalk] Wow & Flutter,    Do new rubber parts need a >     break-in period? > Message-ID: >     > Content-Type: text/plain; charset="UTF-8" > > Hello, Tom.

In some machines you need new pinch rollers anyway and, AFAIK, the only relatively good, although expensive, alternative is Black Reel. Fortunately, most Naks has good pinch rollers. I noticed that many japaneese rubber parts of the early 80's, even belts in some cassette players, are incredibly durable. Most Nak belts are in good condition now except they have stretched (for example, original mode (cam) belts must be replaced because they are highly loaded). Rollers are usually more durable than belts so there is a good chance that original ones can be used for the very long time. Capstan belt is also not sensitive to stretching in decks with stabilized capstan speed (those with FG coils) so you can keep the original one (in simpler machines, where there is no capstan speed feedback but just motor voltage stabilizer, capstan belt stretching results in audible increase in tape speed so you need to adjust it but can keep the original belt). 2019-01-22 6:55 GMT+03:00, Tom Wiedmann : > Andrew, thanks so much for the detailed response.  I have good test tapes > and a T-100 as well as the WFGUI 8 by Alex Freed that is available on Alex > Nikitin's site, so able to make reliable measurements.  I have measured W&F > with swapping the parts one at a time, and have come to some conclusions. > The earlier info I got from this board is correct, with the Nak classic > transport, the capstan belt makes the most difference, but the pinch rollers > are a smaller but still noticeable contributor.   I have tried PRB belts and > some others, and none of them come close to W&F performance that I get with > the belt the deck came with.  It seems to be in good condition, so for now I > will keep using it.  I am awaiting some belts from Marrs, so am anxious to > see how those perform.  For pinch rollers I have used the Black Reel ones, > and although they look good with bronze bearing and all, they do not perform > as well as the ones the deck came with.  They look good, but they must be > out of round, are have some density variations in the material.  Expensive > and apparently, not worth it.  So it sounds like using the original parts if > possible are the best way, unless they are too worn or damaged.  I cleaned > up the ones the deck came with with some rubber reconditioner and > reinstalled them along with the original belt and I measure an incredible > .04% weighted rms and .07% peak consistently on the high side, sometimes a > bit less.  That's darn good. > Is your reference to the "fantastic parts for audiophile level " an actual > source of parts or just a figure of speech?  I haven't been able to find > anything other than the black reel and some generic unbranded ones which I > won't bother with. > Thanks again, great to chat with Nak fans! > > > On Sunday, January 20, 2019, 10:33:52 PM PST, Andrew > wrote: > > Hello, Tom.

You are perfectly right with the original Pinch rollers. Once did get pinch rollers from Nak in Japan. Made in 2009. After that I did ask them why they look ROW. Like old rubber. The Nak technician told me the rubber surface is not flat. it is a litte round . Like you see on the drawing inside the SERVICE manual. And the Rubber surface is not polished , it is a little ROW, to get more friction on Capstan and tape. I think If we do not use alcohol to clean the roller , they may last even more decades. regards Gerhard GERHARD WARTHA KIRCHENGASSE 41 | 1070 WIEN | AUSTRIA Tel : + 43 (0) 650/5266705 > Am 22.01.2019 um 07:11 schrieb Andrew via Naktalk : > > Hello, Tom.

It has a clean set of Nak original pinch rollers which were chosen to be in good shape with minimal wear.  They've been cleaned with rubber rejuvenator very mildly, and all transport moving parts have been serviced and freshly lubed.  I ran some back to back Wow and Flutter measurements on every belt variant I had available to me, having just received my order or Marrs belts, and already having some others on hand. Here's my test procedure: 1)  Warm up the Deck, T-100 Analyzer, and MiniDSP DAC for 1 hour at stable room temperature.2)  Install the capstan drive belt of interest, play the Teac MTT-111N 3khz Full-track Reference tape and normalize the different speeds produced by different belts by adjusting to center frequency using the T-100.3)  Using MiniDSP and the Alex Freedman WFGUI version 8, perform a 30-second Din weighted W&F recording for that belt.4)  Import the file into Minitab and plot distribution curves for frequency and RMS % weighted W&F.5)  Record the Mean and Standard deviation values along with the distribution plots for comparison.6)  Install the next belt7)  Rinse & Repeat Here's the DIN weighted rms % results: 1)  Original Nakamichi 5mm belt:  Mean - 0.031%; Std Dev - 0.005% 2)  PRB 4mm belt:  Mean - 0.054%; Std Dev - 0.005%3)  Marrs Communications 4mm belt:  Mean - 0.056%; Std Dev - 0.006%4)  ESL Labs 5mm belt:  Mean - 0.064%; Std Dev - 0.009%5)  Generic Ebay 6mm belt:  Mean - 0.106%; Std Dev - 0.007% It's clear to me that if the original Nak rubber is still in good condition, it will provide the best performance.  I found that to be true of the pinch rollers as well, although they don't move the needle as much as the belt does.  I didn't list the weighted peak figures but in general they are roughly double the rms value. Hope someone finds this info to be of use. Regards,  Tom -------------- next part -------------- An HTML attachment was scrubbed...

And there's no use of talc afterward or anything else....been down that rabbit hole myself....don't do it. This would be an interesting experiment if you have some solid but stretched OE belts.

An interesting side note, the old stretched NAK belts produce very nice W&F figures on my 'reference' deck with the old but good pinch rollers and a fully cleaned and lubed transport.  Those numbers are better than the new belts will do on that same deck.  On other decks the looser belts produce higher numbers than the new ones.  Obviously more variables in play. Jeff clued me in that the old Mabuchi capstan motors EG-510ED-2B are often junk when they are aged, and give high W&F numbers.  The old style is unregulated, and you adjust the speed via a pot that can be accessed from a hole in the back of the motor.  He mentioned that there is a newer style motor which has internal feedback for speed regulation.  Well I found some of those; they have a designation of EG-530AD-2B, and was able to purchase a few brand new.  There are a lot of Chinese knockoffs out there that have the same part number, but lacking the Mabuchi logo, but the ones I bought are real Mabuchis.  They should be arriving tomorrow, so I hope to try one out shortly.  Maybe that will give some improvement on the really poorly performing decks.  It will take a little work to remove the brass pulleys off the old motor shafts and get them onto the new ones.

Things just start to sound 'dull'. Others do it routinely by the number of hrs on the playback or record head. Kevin I've always been curious when it's necessary to demagnetize our cassette deck heads and other metal part in the cassette well. I'm well past the age where 20-20K was possible but I recall a procedure where you record a passage with the record level at zero and when played back, if you heard some noise, it meant demagnetizing might be in order. I'm just curious when others believe this procedure needs to be done. -- Roland -------------- next part -------------- An HTML attachment was scrubbed...

Nowadays there are big variety of rubbers,and very good properties can be achieved by mixing them.

In RAMM mode AND Fwd direction, when the blank is detected, the deck goes in RWD mode but does not stop as it should (to come back to the very beginning of the recorded area) but rather keeps going rewinding until I push the STOP button. This problem is not related to the blank detection as the latter is indeed detected, but rather to the "momentary rewind" at the bottom part of Fig. 2.3.3 of the 680 SM and to the last paragraph on page 30. Accordingly, I have changed IC-412 (4071) and IC-410 (4049), C444 and checked D456 (which was good): nothing better.

Sometimes the Record switch contacts get oxidized. The switch is located on the Main Board and has a linkage wire that goes to the transport. I have also seen the Nylon parts where the transport cable attach crack from age. Also, be sure that the transport cam markings line up with the pointer for each of the transport modes.

Than check the connectors inside the deck by moving them out and in some times. And sorry Guth! A missing Channel has nothing to to with the cam wheel . There is a small chance for a tape transport foult, But if one channel is 100% gone, than it would be a electrical foult.

Took it out of storage and it was missing a channel. I replaced all of the orange caps to no avail. Then I replaced the Dolby chips to no avail. Finally, I replaced 2 caps in the Dolby circuit and it fixed the problem. I don’t have access to all of my records right now as we still haven’t finished moving back into our house after the eruption. The cap(s) that failed are NOT orange caps and are in the Dolby circuit for the channel that failed. I may be wrong, but I seem to recall it was a green colored cap that caused my problem. Since the 581 does not have “Double Dolby”, all you have to check are those caps in the Dolby circuit for the right channel. Of all the things recommended, this is the easiest one to check. Good luck! Cheryl From: Naktalk On Behalf Of Peter Tanner via Naktalk Sent: Sunday, November 24, 2019 11:10 AM To: Talk about Nakamichi Cassette Decks Subject: [naktalk] 581 Hi everybody, I have a 581 that was in storage for a year or so. I hooked it up the other day and the right channel was gone. Only a lot of hiss with or without Dolby. Worked well a year ago. I checked all connections and wires, everything is okay. No soldering problem on the playback head and the deck is mechanically good. I cleaned the heads again, demagnetized them but no change. The left channel is fine but there is no sound coming out of the right one. Only hiss. If anyone has an idea please let me know. I'd appreciate any help, thanks Peter -------------- next part -------------- An HTML attachment was scrubbed...

It shares the Dolby ICs between the Record and Playback circuitry. That is the purpose of the "Record Slide switch", SW301, on the main board. The Record switch is tied to the transport with a cable so yes, if the mechanism cam is not turning all the way into the play position then one channel may not have the record switch contacts lined up. Gerhard, I believe that you are thinking of the Nakamichi 582 that has real time tape monitoring during record. There is no "Tape/Source" switch on a 581. >From the 581 Service Manual: [image: image.png] Thanks, Doug Guth HiFi Hospital > > Message: 2 > Date: Tue, 26 Nov 2019 06:16:46 +0100 > From: Gerhard Wartha via Naktalk > To: Talk about Nakamichi Cassette Decks > Subject: [naktalk] Missing 581 cannel > Message-ID: <4DA0AD0E-D001-4E30-AFED-0EC9F63878E7 at gmail.com> > Content-Type: text/plain; charset="utf-8" > > Hi, Check the source switch first.

And, yes, You were right Norman. The playback head was the problem. I had another transport actually a 582 but the head assembly is the same on these decks so I simply switched heads, cleaned and re-calibrated the 581 and now it plays fine. I have no idea what went wrong with that head. I have the whole head block here, I guess it is now not reparable so my other, spare transport can only be used for parts. And Cheryl, I have not changed any of the caps in this deck and I'm trying to avoid it as it's a big job. As long as it plays fine I'll leave it as is. I'll be using it for playback only anyway. But thanks anyway. Peter -------------- next part -------------- An HTML attachment was scrubbed...

I’ve changed all orange caps and after that the crackling sound disappeared for about a month. It is back now unfortunately. It will play fine for half an hour or so then it develops this crackling/rumbling sound in the left channel only regardless of Dolby setting. Once the deck is off for a short while then turned back on it will again play fine for about half an hour then the same. Left channel only. No idea what it could be caused by and it’s a pity as it has a better sound than the 581. > Someone mentioned something about filter caps but I don’t really know how to go about that if that’s the case .

You may have noticed some delays in shipping as well as delayed responses to your emails over the past few weeks. I would like to apologize to you for any inconvenience this may have caused. I had to take some personal time away from work to take care of my dad, Fred. For those of you who don't know who Fred is, he started Marrs Communications back in 2007 and was the sole owner until handing the company over to me in 2017. Fred has been battling bladder cancer for the past three years. He is also in end stage renal failure and receives dialysis treatments 3 days a week. In addition, he has also been dealing with some severe depression over the past several months. Because of Fred's condition, it was critical that I step away from Marrs temporarily to ensure that my dad received the correct treatment for some of his health concerns. This came suddenly and without warning so I was unable to contact any of our customers. Normally, I would not share my family's current personal struggles with the public. However, I felt it was necessary to provide our customers with an honest explanation for the recent delays. Fred is back at home and is working to improve. There are good days and bad days, but we make a little progress each day. I know that some of our customers are upset and discouraged. I completely understand this as I would be discouraged as well. I fully accept responsibility for the delays and lack of communication. I am aware that many of you are still waiting on orders. I am working as quickly as I can to get these orders shipped out and respond to emails. With that being said, please do not respond to this email with rude or disrespectful comments. Know that if I could change the situation I would. But unfortunately I can't. So I simply ask that you understand my situation and keep rude or unpleasant comments to yourself as my family and I are dealing with a quite a bit at this time. Again, I am working as quickly as I can to get past due orders shipped out. Please keep in mind that with Fred's health, it is possible that I will need to step away again for a few days. But I will do my best to make customers aware if and when this happens. If you have any questions regarding your order or any other general inquiries, please feel free to contact me at krista at marrscom.com or 346-328-2106.

There are good days and bad days, but we make a little progress each day. I know that some of our customers are upset and discouraged. I completely understand this as I would be discouraged as well. I fully accept responsibility for the delays and lack of communication. I am aware that many of you are still waiting on orders. I am working as quickly as I can to get these orders shipped out and respond to emails. With that being said, please do not respond to this email with rude or disrespectful comments. Know that if I could change the situation I would. But unfortunately I can't. So I simply ask that you understand my situation and keep rude or unpleasant comments to yourself as my family and I are dealing with a quite a bit at this time. Again, I am working as quickly as I can to get past due orders shipped out. Please keep in mind that with Fred's health, it is possible that I will need to step away again for a few days.

I’ve changed all orange caps and after that the crackling sound disappeared for about a month. It is back now unfortunately. It will play fine for half an hour or so then it develops this crackling/rumbling sound in the left channel only regardless of Dolby setting.

I've changed C 118 which was originally an orange cap in the left Dolby circuit. This was the second time and I put in a high quality cap. It played well, silently, for about an hour then the crackles were back again. I saw those electrolytic caps nearby, there are two or three of them. I have to find out if I can get hold of any new ones or some good old ones. The Dolby, by the way, works well so I don't think it's the chip. Difficult to figure out how to proceed with this.

I've changed C 118 which was originally an orange cap in the left Dolby circuit. This was the second time and I put in a high quality cap. It played well, silently, for about an hour then the crackles were back again. I saw those electrolytic caps nearby, there are two or three of them. I have to find out if I can get hold of any new ones or some good old ones. The Dolby, by the way, works well so I don't think it's the chip. Difficult to figure out how to proceed with this.

Hess ; Talk about Nakamichi Cassette Decks Subject: Re: [naktalk] Loss of Rt channel on play head Hi, Another quick thing to check might be a couple of dual polarity electrolytic caps that are in the signal path. The ICs will always be in the signal path and part and Dolby is either enabled or disabled within it. This seems to be a capacitor issue so there might be other caps in the signal path that might be giving grief. Remember that they are all 40 years.

And, yes, You were right Norman. The playback head was the problem. I had another transport actually a 582 but the head assembly is the same on these decks so I simply switched heads, cleaned and re-calibrated the 581 and now it plays fine. I have no idea what went wrong with that head. I have the whole head block here, I guess it is now not reparable so my other, spare transport can only be used for parts. And Cheryl, I have not changed any of the caps in this deck and I'm trying to avoid it as it's a big job. As long as it plays fine I'll leave it as is. I'll be using it for playback only anyway.

You may have noticed some delays in shipping as well as delayed responses to your emails over the past few weeks. I would like to apologize to you for any inconvenience this may have caused. I had to take some personal time away from work to take care of my dad, Fred. For those of you who don't know who Fred is, he started Marrs Communications back in 2007 and was the sole owner until handing the company over to me in 2017. Fred has been battling bladder cancer for the past three years. He is also in end stage renal failure and receives dialysis treatments 3 days a week. In addition, he has also been dealing with some severe depression over the past several months. Because of Fred's condition, it was critical that I step away from Marrs temporarily to ensure that my dad received the correct treatment for some of his health concerns. This came suddenly and without warning so I was unable to contact any of our customers. Normally, I would not share my family's current personal struggles with the public. However, I felt it was necessary to provide our customers with an honest explanation for the recent delays. Fred is back at home and is working to improve. There are good days and bad days, but we make a little progress each day. I know that some of our customers are upset and discouraged. I completely understand this as I would be discouraged as well. I fully accept responsibility for the delays and lack of communication. I am aware that many of you are still waiting on orders. I am working as quickly as I can to get these orders shipped out and respond to emails. With that being said, please do not respond to this email with rude or disrespectful comments. Know that if I could change the situation I would. But unfortunately I can't. So I simply ask that you understand my situation and keep rude or unpleasant comments to yourself as my family and I are dealing with a quite a bit at this time. Again, I am working as quickly as I can to get past due orders shipped out. Please keep in mind that with Fred's health, it is possible that I will need to step away again for a few days. But I will do my best to make customers aware if and when this happens. If you have any questions regarding your order or any other general inquiries, please feel free to contact me at krista at marrscom.com or 346-328-2106.

You may have noticed some delays in shipping as well as delayed responses to your emails over the past few weeks. I would like to apologize to you for any inconvenience this may have caused. I had to take some personal time away from work to take care of my dad, Fred. For those of you who don't know who Fred is, he started Marrs Communications back in 2007 and was the sole owner until handing the company over to me in 2017. Fred has been battling bladder cancer for the past three years. He is also in end stage renal failure and receives dialysis treatments 3 days a week. In addition, he has also been dealing with some severe depression over the past several months. Because of Fred's condition, it was critical that I step away from Marrs temporarily to ensure that my dad received the correct treatment for some of his health concerns. This came suddenly and without warning so I was unable to contact any of our customers. Normally, I would not share my family's current personal struggles with the public. However, I felt it was necessary to provide our customers with an honest explanation for the recent delays. Fred is back at home and is working to improve. There are good days and bad days, but we make a little progress each day. I know that some of our customers are upset and discouraged. I completely understand this as I would be discouraged as well. I fully accept responsibility for the delays and lack of communication. I am aware that many of you are still waiting on orders. I am working as quickly as I can to get these orders shipped out and respond to emails. With that being said, please do not respond to this email with rude or disrespectful comments. Know that if I could change the situation I would. But unfortunately I can't. So I simply ask that you understand my situation and keep rude or unpleasant comments to yourself as my family and I are dealing with a quite a bit at this time. Again, I am working as quickly as I can to get past due orders shipped out. Please keep in mind that with Fred's health, it is possible that I will need to step away again for a few days. But I will do my best to make customers aware if and when this happens. If you have any questions regarding your order or any other general inquiries, please feel free to contact me at krista at marrscom.com or 346-328-2106.

I followed your advice and sprayed the Dolby chip while the deck was crackling during playback. The crackles and rumble did not go away immediately but after about 5 minutes it did. The spray was a can 3 in 1 which is besides being a contact cleaner it is also a penetrating fluid.I was wondering if that penetrating fluid didn't do some unexpected cleaning on or around that Dolby chip. The deck is from 1981 so it's old. Before I used that spray, by the way, I'd put it in the freezer to make sure it was cold. Obviously it was not a capacitor problem after all considering that I had changed all the orange caps anyway. I have an extra Dolby chip from a donor board but so far it's playing really well. I had it on for about 5 hours an there was no noise. Desoldering the Dolby chip while trying not to damage the board is a real job so at this point I'll leave it as is. If it starts crackling again I'll change it. Thanks a million for the advice and to all who suggested as well that the Dolby IC could be the culprit. Peter ________________________________ From: perry esposito Sent: Thursday, November 28, 2019 7:22 PM To: Peter Tanner Subject: Re: [naktalk] Loss of Rt channel on play head Typically, when a noise like that shows up due to heat (that is the most likely cause when it comes after a while and goes away when turned off), it is either an IC or a transistor. On Naks it is often the Dolby IC. Even with Dolby "OFF" the signal still goes through the Dolby chip, it just bypasses the actual noise reduction part. Easiest diagnosis is a can of component cooler, that you can spray on the chip when in operation. If the noise goes away when cooled, you have your culprit. It may also be the muting transistor. When not in play or record, the muting transistor sends the output to ground for total silence when stopped. They often get weak and will also send the signal PARTIALLY to ground during operation, which sounds like static/crackling. Easiest diagnosis is to remove the muting transistor and the noise will go away (but music plays fine) if the transistor is the issue. Of course, there will be background noise from the deck in Stop, as well.

I’ve changed all orange caps and after that the crackling sound disappeared for about a month. It is back now unfortunately. It will play fine for half an hour or so then it develops this crackling/rumbling sound in the left channel only regardless of Dolby setting. Once the deck is off for a short while then turned back on it will again play fine for about half an hour then the same. Left channel only. No idea what it could be caused by and it’s a pity as it has a better sound than the 581. > Someone mentioned something about filter caps but I don’t really know how to go about that if that’s the case .

In my experience the clicking occurs when the azimuth adjusting motor reaches the end of its adjustment range. In my tape restoration business, I learned that this was caused by tapes that were outside the range of the NAAC system and for a long time I used MR1s to manually adjust the azimuth for these tapes. This can also be caused by a dirty play head (some, but not many, cassettes exhibit sticky-shed syndrome which quickly clogs the heads. Wet cleaning is the only way to really get that junk off. Of course, bad/dirty pinch rollers can create an azimuth skew as can dirt on any of the guides or capstans. Anyway, there is a procedure in the service manual for manually adjusting the azimuth. In essence, it focuses on making certain the NAAC is in the center range and then adjusting for correct azimuth using the play azimuth adjustment gear wheel. If you think your record head is fine, you can use that as a source of azimuth adjustment, otherwise you'll need to start with an azimuth calibration tape. I have adopted a practice for some tapes that are badly off-axis but really high-fi to mis-adjust the play head azimuth so that it is correct with the NAAC centered for that tape. Then recalibrating back to normal azimuth after that tape. It is easier to do on my Dragons because I have used the spare switch pole on the Timer play/rec switch to disable NAAC (you won't need NAAC if you are using timer record mode). Actually it does more than just disable, it brings the motor terminal out to the Gizmo four-pin jack, leaving ground and bipolar power available. I use a miniature spring return toggle switch mounted in a small diecast box to manually adjust the azimuth during playback. While I was typing this, I was watching a two-track quarter-inch reel that needed TLC manual azimuth adjustment, as an example (done with a hex key to give a better indication). For reel decks, if you're going to do this, lubricate the azimuth screw/nut with lithium grease to prolong its life. If you wish to use a program that displays azimuth as a strip chart, you can use StereoTool.com, but I think you have to buy the license to get the azimuth detector or at least if you're using it as a VST plug-in, but it's the lowest level license. Don't run the audio through StereoTool as it downsamples to 44.1/48 if you're doing 96 or above sampling,  but I run it in an aux bus of my DAW as I ingest tapes. Here is the documentation page for the Stereo controls which includes azimuth. I think all functions are available under a demo condition...but I haven't used it for much other than azimuth display https://www.stereotool.com/documentation/9.23/stereo/ Cheers, Richard On 2019-12-09 8:43 a.m., Marcelo F Mansour via Naktalk wrote: > > Sure I bought a new Maxell UD-90 and to do a recording and the > clicking starts but after some seconds disappears. > > I recorded both sides with almost no clicking, few seconds only, but > when I play the clicking starts again and do not stop anymore……….. > > Rgds, > > Marcelo > > *De:* Naktalk *Em nome de *josephjean > via Naktalk > *Enviada em:* domingo, 8 de dezembro de 2019 15:26 > *Para:* Marcelo F Mansour via Naktalk > *Assunto:* Re: [naktalk] Dragon-NAAC > > As you've pointed out, the clicking is from the NAAC. > > Have you tried to record on the deck?  Does the clicking stop? > > Have you tried known good tapes?  If your 80s version were known good > tapes, then you most likely have the NAAC issue of not finding the > sweet spot. > > Sent from Samsung tablet. > > > > -------- Original message -------- > From: Marcelo F Mansour via Naktalk > > Date: 12/8/2019 10:51 AM (GMT-05:00) > To: 'Talk about Nakamichi Cassette Decks' > > Subject: [naktalk] Dragon-NAAC > > Hi Everybody, > > I bought recently a Dragon and I picked up some cassettes recorded a > few years ago and just recently got around to listening to the music > on some of them. > > Some of it is pretty good but I'm also getting some clicking from the > NAAC on some of the tapes, I stop and use FF and REW and play in > reverse mode but the clicking still there. > > Is this heads misalignment?

If the torque value too little or too much, it can cause this phenomenon. At least you have good pinch rollers. The sony decks are notorious for these wearing down fast...I wonder if the capstans were swapped out and are in backwards? (I haven't worked on the RX505, but I know some dual capstan decks have slightly different capstan sizes...which would throw things off!)

At the beginning or end? Make sure takeup torque is good (around 55 g/cm), Philips spec is 55 +- 10 g/cm (Philips invented the compact cassette). If it's high, take out the takeup spindle and rough up the felt in the slip clutch. It could be a lot of things. I'd take the transport apart, clean as much of the old lubrication out as I could, relube it with synthetic oil and lithium grease where appropriate. The cams get grease, the capstans get a little light synthetic oil. These things are 40 years old, anything can happen. If it bunches only long tapes (C-90 or 120) at the end, try changing the back tension. If it chews tapes at the beginning, it could be excessive takeup torque. The slip clutches can get sticky and pull the tape with too much tension when they get old. That is due to the felt in the clutch crushing down and not being "slippery" enough.

Do you have the service manual for this deck?  I have a DVD of all Nak service manuals, found it on ebay. If so, check the pinch roller tension, the specs are in the manual.  You can use a fish gauge. Perhaps you can measure the pinch roller position with calipers (cheap at harbor fright) to get it back into position after removing and relubricating it. I asked before.  Which tapes skew and at what point, start or end?  Are they very long tapes like 90 or 120? Back tension and takeup torque makes a difference, so does pinch roller height.  Pinch rollers are not flat, they are somewhat convex (bigger at the center), just very slightly. You'll get it, take your time. -Fran On 2/14/19 4:26 PM, bb via Naktalk wrote: > > yes, there is the usual stroke adjustement as in all other classic > transports. > > > Le 14/02/2019 à 23:20, Thomas R a écrit : >> Is there anything like a head base stroke adjustment on the 505 ? >> I've seen such an adjustment on other Nak decks .   Thomas . >> >> On Thursday, February 14, 2019, bb via Naktalk >> > wrote: >> >> Dear Naktalkers, >> >> I have a RX-505 which I have overhauled in the past (about 4 >> years ago). >> >> It came back to me because the tape was skewing with a rapid >> decrease of the sound after play being engaged. >> >> I began by the usual demagnetization and cleaning, but nothing better >> >> I then dismantled it, split it, cleaned everything, relub, >> changed the belts(both control and capstan), the rollers, >> realigned everythning with the Nak gauges.... >> >> >> But...the tape keeps skewing!!! >> >> Any idea would be more than welcome because at that point, I am >> now puzzeled !! >> >> ========---------------------------------------------------------========= >>          Also check out the wiki! http://wiki.naks.com >> ========---------------------------------------------------------========= >> Naktalk at lists.naks.com mailinglist >> Maintain your account here: >> http://lists.naks.com/mailman/listinfo/naktalk >> >> ========---------------------------------------------------------========= >> > > > ========---------------------------------------------------------========= > Also check out the wiki! http://wiki.naks.com > ========---------------------------------------------------------========= > Naktalk at lists.naks.com mailinglist > Maintain your account here: http://lists.naks.com/mailman/listinfo/naktalk > ========---------------------------------------------------------========= -------------- next part -------------- An HTML attachment was scrubbed...

Here is what I found: - the two flywheels had no axial play at all. On the advice of Norman, I checked them and tuned them according to the SM by turning back half a turn and locked them. - I had one "tic" foaward to the mechanical stroke adjuster - I changed again the belt and put a new guenine one from 1997 (one with the famous white triangle) The deck is now working perfectly. Will check it for a while now I really think that the problem was coming from the no-axial play for the flywheels. What I do not understand is the way it comes to this point as the deck has been working very well before ??? I would expect that the axial play would increase because of usage... Another point of detail is the fact that on the RX-505, the spring labelled "16" on page 26 (fig 5.22) of the SM is always lacking. Does anyone has an explanation ?

There are a lot of transports where the axial play becomes zero after rebuild. Also check the speed again, maybe now it is running to fast.

Managed to fix a couple of problems. I wonder if I could bother you again. The 481Z suddenly stopped producing any sound. The transport is okay, all works. The meter lights up but it does not react when I play a cassette. Total silence. It played just fine the day before and when I turned it on again there was no sound out of it. I wonder what it could be caused by. The 480 had a reel motor change. It played fine after that for about a week but now it has developed a crackling sound in the left channel. The right channel is fine. The transport works fine. But the hissy, crackling sound is quite loud. The left channel meter keeps moving in play even when there is no cassette in the deck. Any help with these would be appreciated.

Hi My 480 still does not fast forward. It plays, records, stops and rewinds, in other words all other functions are good. The transport looks ok. In fast forward the mechanism comes up but the idler wheel does not move over to engage the reel so it goes back to stop. The reel motor works fine in play and rewind. Any ideas? Thanks.

These crackles may be due to any orange cap or (with much smaller probability) any electrolytic in signal path, or due to cracked/cold soldering. Slight and gentle PCB deformation + visual inspection may help to identify if there are problematic solder joints (some people use hot air also). I recommend to inspect all PCBs anyway if you service the deck for the soldering problems, pay most attention to areas where heated parts are located (power transistors or so, where the PCB may have slightly brown color) and mechanically loaded parts like input/output jacks (for example, if RCA jacks are soldered-in directly in PCB, these solderings are very often cracked). Classic example of cracked power transistor solderings is direct drive output stage in Naks (they need not too small heatsink for the reliable thermal regime in real life, while engineers that developed didn't use heatsink for them at all, so if the mecha is not in ideal condition, these transistors overheat, they may degrade or fail, and their solder joints crack). This is not about the signal path, but also a place to inspect (or do preventive soldering) if anybody have the DD in his/her Nak. In some cases there are failed semiconductor, like PB amp first stage transistors, that cause crackle noise (although it's rare). 2019-02-19 19:32 GMT+03:00, Peter Tanner via Naktalk : > Fran, > > I've changed two caps near the Dolby chips in the 480 and cleaned the record > switch.

I can't see my 481Z manual anywhere, but am assuming a strong similarity to the 481. In a 481, muting is applied to the Line Amp and Meter Amp by Q104 (left) and Q204 (right) on the Main PCB. Both these muting transistors are controlled by a common muting line that originates from the collector of Q416 also on the main PCB. Since you've lost both audio channels and both meters, it is likely the a muting signal is being sent to Q104 and Q204. Near Q104 and Q204, are test points TP101 and TP201. These should still have audio signal, even if the muting signal is present. So check for audio signal on these test points (using a CRO preferably, or an AC mV meter), and verify that this audio signal is lost at the emitters of Q104 and Q204. This will tell you if the problem is the mute line from Q416. If it is a muting problem, it could be a discrete logic problem somewhere up to Q416, or a mute delay circuit that also contributes to the mute signal, and maybe even Fuse F402 (500mA delay type). Good luck. Hope there are strong similarities between 481 and 481Z circuit diagrams and nomenclature. If there aren't, all my words above won't help much. I'll keep looking for my 481Z manual.

I'll check this out but I have a question. The TP 101 and 201 I used for checking the playback level with a 400 Hz tape. 90 mv in this deck. So do I put a 400 Hz tape and check if I have 90 mv? I bought this deck some 8 or so years ago. Other than the usual transport hassles which got fixed it played well. Used it regularly. Then it started to have electronic problems. There my abilities are rather limited. Scott Garner helped me fix a problem in the Dolby C circuit and a mute problem as well 4 years ago. Then the problem was that it didn't mute when it should have. Now it's the reverse. The only other anomaly I'm noticing now that it's opened up is that in stop the capstan motor keeps turning. My understanding is that unlike other models in the 480 series, Z including, the capstan motor should stop when the stop switch is pressed. At least that's what happens in my other deck which is a 480. The main difference between the 481 and the 481Z besides the LED meters and the Dolby C is the separate logic board in the Z models. Kind of a hassle as you have to remove it in order to measure things under it on the main PCB. Then one has to be really careful it doesn't touch anything while the power is on as it can short something out. Anyway thanks for your help, I'll get back to you with the measurements.

I have a 550 with the cassette well spring D broken (part 0C03973A, labelled 21 on page 23 of the SM). This is the blade-shaped spring that allows the well plate to eject the cassette. I have tried to solder it with tin but after 3 to 5 openings, it brakes again and does not act as as spring any longer. Would you mind checking your drawers ? P.S: it is surprising how this deck sounds!

He gave it away without mentioning it to me sadly as i found it more interesting than my 670 and the Cassette Deck 1 I put it down to the non cd voice it had... after cd's arrived Nak voicing changed to compete in my opinion.... so for me the 481's are keepers.

The mechanics are fine. All works except there is no sound. The meters don't move either. Fast forward, rewind, play, record, pause function as usual. The deck worked okay the day before. Any ideas?

Now the signals on the ZXL is ok (get back to it), but the ZXE will light up all LEDs before I press play. Then it will have the LEDs indicate signal strength of -20 db for a 315 HZ test cassette that on all my other Nakamichi decks, give +3 db, (Teac MTT-212N) for a short while, before it reduces to slightly below -30 db. Playback strength form output phono and headphone is normal. Next: ZXL; This has normal LED indication, but there are no sound from output phono connection, or headphone. But if I connect phono cables to the decoder output connections (for external dolby unit), there are playback sound, approx. same strength, as my serviced ZXL. (My last ZXL is also like that, but no LED movement) Both the ZXE and ZXL will calibrate and record, with normal signal indication on the ZXL, but very weak indication on the ZXE.

I would suspect some open electrolytic capacitors in the driver circuit (IC501) for the LED, specifically C513 and C510. These caps provide a slow ramp to gradually increase or decrease the light output from the LED and correspondingly slowly fade up or down the audio. If the caps are open or have high ESR (series resistance) then the fader will quickly changed the audio levels, more of a switch than a fade. These component designations are from a schematic for the LX-3, I don't have one for a LX-5, but I would expect it to be similar if not the same. Just change the 2 electrolytic caps around IC501, there's a good chance that's it.

I'm just curious...im not looking for overnight delivery...im happy with 2-3 weeks. All of the reports I've read from others have experienced the same issues... but who knows? Maybe I'm one of the lucky 1% people who were unlucky to ever received their belts from marrs. Twice. Right. I'll stick with paying other stores that have shipped without fail time after time. I'm more than content to wait a few weeks. Here's a better question : has anyone ordered from marrs any belts in the last few months and received them?   Original Message   From: naktalk at lists.naks.com Sent: March 6, 2019 07:36 To: srieker at verizon.net; naktalk at lists.naks.com Reply to: glennaskin at optonline.net; naktalk at lists.naks.com Subject: Re: [naktalk] Marrs Update I have observed that there have been episodes in years past where some orders were taking far longer than customer’s most optimistic expectations.

If you require a good product to keep your unit in close to Optimal performance, then the wait is worth it. If you just want to "get the unit up and running", & don't really care about Performance, then yes there are other suppliers out there for your situation.

Nakamichi decks are performance machines. They are also precision machines. In their day, they were the best cassette decks you could buy. Don't forget, cassette decks were meant for voice recordings, not audiophile quality music. Nakamichi performed an engineering miracle. They turned a voice deck into an audiophile music deck.

But when I complained about the counter belt for the 600 that it was to short and actually so short that the deck would not turn the takeup reel and counter. He did not answer in any positive way. I gave the measurements for his belt, the original belt and the length of a cord measurement round those turning points. The Marrs counter belt is a couple of centimetre shorter than original. I bought three sets for 350-550 and 600. Also on tapeheads.net there were a discussion about belts for the Alpine/Alpage AL-300, where he had delivered wrong belts. I thought he then would have changed and ordered a set. But my set is also the wrong dimension. Will I order from him again? Possibly, but only belts for the "Classic" transport.

I have tried various sources for belts for the Nakamichi classic transport. It has been difficult to find one that results in the tape deck being within specification for W&F. The only belts I have found to meet specs have been Marrs. At the moment, it seems that I would need to spend $60 USD for one capstan belt, which I am reluctant to do. The belts from WJOE.com are less expensive, but I can't make them meet spec, they do come close however and are probably good enough for most ears, but I like meeting the original numbers. I am measuring using a Sound Technology 1510, so I know I am getting accurate readings of speed and W&F. The PRB belts of about 15 years ago were the worst by far for W&F, WJOE's are better, but the Marrs belts are definitely preferred, but at $50 or $60, I'd like a good alternative. I don't mean to complain. I know nobody is making a mint selling belts for cassette decks.

JAPAN Auction” then you select “Electronics, AV & Camera” then you select “Audio Equipment” and many options will appear and select “Cassette Decks”, you’ll see many brands of cassette decks, then you can write “Nakamichi” in the searching engine”What are you looking for?, after all steps you will see many bids for Nakamichi decks and if you can see belt bids and Nakamichi’s as 1000ZXL/DRAGON/CR7A-CR70/ZX-9…… I hope that I helped you and as these bids are unknow persons maybe you will see belts for sale or not, but I bought my belts with person in Japan that worked for Nakamichi during many years, these belts had Nakamichi codes in the plastic bag, if these are original is hard to confirm you, but both decks that I have works perfectly after I installed them. Any other information please feel free to contact me.

In their day, they were the best cassette decks you could buy. Don't forget, cassette decks were meant for voice recordings, not audiophile quality music. Nakamichi performed an engineering miracle. They turned a voice deck into an audiophile music deck. If you do not care about this, and don't care to keep your deck in top performance like it was meant to be, then yes, buy crap belts. You will be destroying the great recording and playback music quality these decks have because you will be destroying the great specs these decks have.

I think that something has fallen down on the machine while it was opened... So, I am in the process of having this board to be manufactured again. The new board will already have the metallic jumpers included as "via" to the component side. The cost will be roughly 80-100 euros per PCB , depending on the final shipping cost. I would like to know how many people would be interested in having such a spare board knowing that I need to make at least 20 pieces. In the same line, I have asked to remanufacture the dust plexi cover of the "Limited" in a very professional way (nothing to compare with the one you can buy on the bay for some 60 euros...!). The only difference is that it will have neither serigraphy nor any "Nak" sign on it to avoid any copyright problem. The cost will be between 100 and 200 euros (sorry, but cannot be more precise so far, as it strongly depends on the number of covers to be produced).

Deck plays and F FWD normally. In rewind sometimes the supply hub won't budge, or if it does start will bog down and go to stop mode about midway through a C-90 rewind. About -6vdc on reel motor terminals while unit is in RWD mode. Disconnected the circuit feed from the motor drive circuit at the logic card and ran the reel motor from an external 12v adjustable regulated power supply. Motor seemed to track speed vs. voltage from 6-10vdc about as expected. What I did notice is that the idler did not snap to the supply reel hub when engaging RWD as it did to the TU reel hub when engaging PLAY or F FWD. In fact it was not even touching the hub. Worked the idler laterally by hand multiple times, after which only light contact was established. If upward ( not lateral ) pressure was applied at L29 with a small screwdriver, the idler engaged the supply hub and drove it nicely. Never having disassembled the transport, it's not clear to me how the coupling between the reel motor shaft and the idler pulley works. It is shown as part of the reel motor assembly ( ref. #72) in the service manual. Is there any history of trouble with this coupling ? Am assuming that this coupling must be removed and transferred to the new shaft during motor replacement. Have any replacement aftermarket couplers been identified to date ? Must not forget to mention that the back-tension belt was not present, nor any debris or remnant of same (??!!) . I'm the original owner of the deck and did have it to a service facility in FL in the 90's. Have a belt on order. Does that belt contribute to the rewind function at all ? Bought a pre-owned CR-7A off eBay which has performed well since about '15. It has an earlier serial than my other deck. To see how the back-tension belt was routed, I exposed the transport from the front and, you guessed it, no back-tension belt or remnant once again. Replaced the belt and confirmed operation in the 2nd deck by creating some tape slack in a cassette before loading it. With the belt in place the supply reel could be seen rotating CW to remove the slack as the cassette door was closed, which is the main purpose of that feature, isn't it ?? Haven't noticed that the absence of the belt affected the shuttle performance of the 2nd deck since I've had it. Thanks.

When powered up, the deck flashes READY as expected but before the flashing ends the deck drops into PLAY mode for a few seconds, then into STOP mode. See cam gear rotation during this process. Will compare cam switches against 11.2(2) Timing chart. Also, the deck is now a confirmed tape-eater, with the take-up reel stopping during PLAY while the tape continues to be fed until the motion sensor shuts it down.

Roger, this switch is considered causing distortions by many pepole, but, IMHO, this distortion is quite small, and you will likely not hear it. BTW, the tape recording itself also introduces distortions at lower and higher frequencies when there are relatively large magnitudes, that's why the recording level is reduced so metimes to minimize distortions although increasing noise. So it's your decision to relace 4066s or to use them as is. I'm not an audiophile so I never replace 4066s.

Need to bring my 1000ZXL and ZX9 to TvdH to have brought back to life.. in the mean time looking at this CassetteDeck 1.5 Sankyo deck I once bought and never tried to fix. It needs a new capstan belt, right now to play something at all. So I was wondering if these belts are also very critical in Sankyo transports? I would think less critical.. Also planning to upgrade C206 R/L 220uF/6.3V to a higher value as discussed online. Until then using a CR-2, that one does not want to break!

Dave Cawley is the face of Time Step and he's a good guy--I've met him at a couple of ARSC conferences. As to the 4066 in the Dragon, since the output of the 4066 feeds the non-inverting input of an op amp and has a 100k resistor to ground, the dynamic impedance variation of the 4066 is only a very small percentage of 100k ohms, but it still could produce some improvement in distortion. Depending on the leakage of C131 and the offsets of the opamp, increasing R141/241 from 100k to 470k or even 680k might actually provide the same distortion reduction as switching to a lower impedance version of the 4066. I don't know the signal level running through these switches, but !C104 is providing a bit less than 20 dB of gain going into the Dolby chip, and my recollection is for Dolby tone the levels going in is well under a volt. The head amp ahead of the 4066 includes the integrator, so its gain is about 70 dB at DC, if it went there, dropping to about 45 dB at 1 kHz....not terribly high voltages. Its gain falls 6 dB per octave, cancelling out the head's 6 db/octave rise.

Apparently it has something to do with the muting circuit. The meters light up but don't move either in playback or record. There is no signal at the test points either. All switches have been cleaned including the large record switch. All fuses are good and the transport works normally. The play functions as before, fast forward/rewind, stop, pause are all normal. It erases as well. Checked the tape on another deck.This deck has no monitoring capability like the 482Z so there is no monitor switch.

But after replacing that and having some problems with the calibration of Level and Bias, I replaced 4 caps in the Bias oscillator circuit. That was hoping to get the deck back to normal calibration. It will calibrate crome and metal tapes ok, but normal tape is very difficult. And especially Bias is difficult to get correct level for. When I checked user manual and also my ZX-7s and Dragons, both Level and Bias meter should increase when I turn clockwise and decrease when turned the other direction. Not so on this ZX-9 ☹ Level is normal, but Bias is opposite of the normal adjustment. I think this has happened after I replaced belt (not likely) and caps. May I have connected something wrongfully, or are there obvious other faults? BR Birger -------------- next part -------------- An HTML attachment was scrubbed...

A coupe of hours after posting, I was able to check more into this. I suspected the IC, but also transistors. I replaced the IC, but no luck. Then I desoldered a couple of the transistors. Then to my surprise after removing solder from two of the legs, that transistor fell of the PCB. When I looked at it, the remaining leg was so short that it had not contacted the connection. I replaced with another transistor and Now full function 😊 But thanks for your replies 😊 Birger -----Opprinnelig melding----- Fra: Naktalk På vegne av Francis Flynn via Naktalk Sendt: onsdag 5. juni 2019 16.45 Kopi: Talk about Nakamichi Cassette Decks Emne: Re: [naktalk] 580 play and FF will not!

I am still running and maintaining 5 Naks, 1 of which I have owned from new...my ZX-9. I also record on two open reel to reel machines which I also maintain. For me it is easy as I am an ex Broadcast technician and I grew up with and love the art of recording and the fun of technical maintenance. But.....I find myself listening more and more to Tidal, not because it is more fun, not even because of the better technical quality...but simply because of the sheer choice and access to wonderful music that I would otherwise never have the opportunity to discover. All of my machines are in perfect running order but I hate to admit that sometimes they are being turned on to maintain mechanical rotation and capacitor forming, rather than for listening purposes. I am still recording playlists particularly on the open reel machines though. For me our Naks are still very special machines, worth preserving and enjoying, all be it a little less often with streaming as the main consumption choice (for me). For those reliant on others to do their maintenance however, I think there is the reality that cost may very well soon out weigh the benefits for some. I hope I am wrong.

I am still running and maintaining 5 Naks, 1 of which I have owned from new...my ZX-9. I also record on two open reel to reel machines which I also maintain. For me it is easy as I am an ex Broadcast technician and I grew up with and love the art of recording and the fun of technical maintenance. But.....I find myself listening more and more to Tidal, not because it is more fun, not even because of the better technical quality...but simply because of the sheer choice and access to wonderful music that I would otherwise never have the opportunity to discover. All of my machines are in perfect running order but I hate to admit that sometimes they are being turned on to maintain mechanical rotation and capacitor forming, rather than for listening purposes. I am still recording playlists particularly on the open reel machines though. For me our Naks are still very special machines, worth preserving and enjoying, all be it a little less often with streaming as the main consumption choice (for me). For those reliant on others to do their maintenance however, I think there is the reality that cost may very well soon out weigh the benefits for some. I hope I am wrong.

I’m new here, having just joined today. I’ve had a 480 since the early 1980s which I’ve sent twice to Nakamichi for service, the last time being close to twenty years ago, I think. It’s due for service and repair again—FF and RW work, but not Play--and I’m not sure where to send it. I’ve seen a lot of places online that might be good repair places, a couple which specifically mention Nakamichi, but I’m not sure which may be best for me. Is it okay to ask for service / repair advice? I live in southern Wisconsin in the US, for what it’s worth. I also have a 700 ii that has a problematic channel; that’s a machine I got 15-20 years ago from a friend, and it’s never been useable because of that problem. I may want to send it off, too, though shipping that machine seems a harder task than shipping the 480. Thanks for whatever help and advice you can give me.

A Nakamichi can do great recordings on any tape. Many until 1983 Japan made Cassettes from type 1 . like Maxwell ( HITACHI ) UD ore TDK D are very good quality . Plus Maxwell XL from that years, 1978-1983 Very Sensitive FE tapes with a huge amount of magnetic materials. Those tapes are very near the Type4 tapes anyway.

Tape releases seem to have been on the upswing for quite a while, and I actually think that this era of streaming services is partly responsible. It's impossible for an independent musician to make anything beyond a token income from streaming services, but tapes are cheap to produce and can be sold just as cheap while still giving musicians a decent return per tape. There's a huge number of independent musicians who would be hard pressed to afford vinyl or even a short run of CDs. But if you have a decent deck and can buy some blanks, a short run of tapes can be produced for very little money -- and even made incrementally on demand as they sell. Anyway among my peers I see tapes, tapes, tapes and more tapes these days! I signed up on this list because I'm thinking of getting a second Nakamichi -- maybe just another BX-150 -- but also was hoping to read and learn more about how to properly maintain the one I have. I'm glad to find the list is still active! Best, Erik -------------- next part -------------- An HTML attachment was scrubbed...

If you're sure that this is the case, you may try to replace the counter belt (Nak belts are very good but they stretch with time as other belts). You may change the mode (cam) belt either as a preventive service because it's the other common belt-related problem in this deck. It's very simple. Changing the NAAC belt is not so simple, and it's not hardly loaded like the cam belt. 2019-06-27 8:35 GMT+03:00, Ural Durusu via Naktalk : > Hello to everyone.

There is no worldwide resurgence in cassette interest. They are being dragged to the landfill daily when found. It's a very finite, niche market. Most millennial's and gen Z's are horrified that this technology still exists. Further proof to them that we're not "relevant' as they love to say. Just to play with numbers....if there were just 30,000 avid cassette users left in the US, that would keep a steady market of decks, tapes and accessories going on eBay. Not to mention keeping techs busy like Tom & Willy. But to think that cassettes are on a comeback trail like vinyl is delusional and you're living in Fool's Paradise. I have no idea what the real numbers are.....I don't think anyone does. But I know they're paltry with respect to the general population listening to music. The reality is that no tech schools are training technicians in anything analog and haven't been for decades. So after established techs like Willy & Tom are gone, these will be museum pieces. We all know how complex Naks are and the specialized tools needed to repair and align them.....so this idea that you'll fix your own doesn't fly either. Sure, you can get in there, prod around, replace belts/idlers, wipe out old lube and replace with new....that's the mechanical part.  When something electronic goes awry, then what? Or, how would you align everything on a Dragon, a 700ZXL or a 600ZX properly without the specialized tools/knowledge? It's the same story in reel to reels; when the techs die out, so do the machines for the most part. I'd be the first to stand in line if there was some sort of training for tape deck repair, or to learn at the feet of a Willy or Tom (and in R2R, Sam P). But as busy as they are, I doubt if they'd want someone hangin' around trying to learn their trade.....plus, you'd have to live close to them because the learning part takes TIME. There was a learning tech here once from the south that did decent work on some decks I sent him. But the membership here was so brutal to him with negativity that he dropped off from posting.  Digital killed the nuances and complexities of analog tape, just accept that fact. Use the decks left while they last and appreciate the techs still devoted to them. The human ear loves the coloration/distortion of 1st order harmonics in analog playback equipment....so enjoy!

You can learn to repair Nakamichi by yourself. Use many youtube cannels to learn C-Mos technic. Or use the Nakamichi Service Manuals from N580, They explain near all C- Mos IC basic used by Nakamichi Than learn some basic electronics like transistor amplification. There are even very good made YouTubes from the US army to understand the needed basic electronic circuits . After that get yourself a not working N480 to work on the classic tape transport. Get this transport going again. Than buy yourself a cheap signal tracer. Or make one out of a kit. That is about all you need. I do use 5 to 7 Nakamichis to listen and keep them alive.

The market  for cassette decks (regardless of head count) is very small these days. As to new technologies, they have marginal significance. Yes, we do have better op-amp IC's; specifically designed for audio; also, better coupling capacitors, etc. But, bottom line, these will do little for a product that only nostalgic aficionados are interested in.

The main problems are mechanical part (unobtainables and alignment) and unobtainables in electronics. All other issues may usually be fixed by the more or less skilled "generic analog" tech. They make analog amps and other hi-fi gear, and lots of units in any equipment are analog so there are specialists that "can do it". If you like electronics and have basic knowledge and skills, read the Internet discussions on your model thoroughly, make the most probable issue list, do the preventive work and you will get the deck with acceptable reliability in most cases. Unobtainables in tape deck electronics are rare. Usually, you can find replacement for almost all parts, if you have basic skills in electronics, as I mentioned above. I may take lots of time, for example, to replace all ecaps, but it's doable. Mecha alignment can be done usually even without gages, although it will be not ideal. I have a Dragon that is in very used condition and I needed to realign it's heads. I have not any gauges. The result is acceptable, on tests, it even calibrated well. I needed about 6 months for the preventive work and to fix the PB head problems (there was a very small metal spike on the PB head surface and it was difficult for me to cope with it, I made some mistakes and it required additional time to correct them). Mecha unobtainables is a problem, I think, mecha aging will be the only condition limiting the life time of old tape gear. Cassette decks has lots of plastic parts that tend to crack and not "semi-ethernal" like metal ones. But metal parts wear so they are not ethernal either, although much more durable. As a result, in my opinion, most devices can live while their mechas work or can be repaired. Yes, they may not perform as new if you only do the simple mecha alignment and electronics adjustment, but the sound will be good for listening. Semi-offtopic. "Maximum target" is engineering and production of new high-quality mecha and electronics from scratch. Electronics, if you don't need noise reduction, can be made even by the amateur. There are lots of analog literature, academic + practical, and tape machine schematics on the Web, there are lots of audio opamps like OPA2134. It will require time but it's more than possible. Mecha part can also be made, full metal, remember that high precision mechanics in HDD that are still produced. Tape machine tolerances are a peace of cake compared to HDD mecha ones. If the head of the very old HDD was a skyscrapper-size, it travelled above the disk surface at centimeter-scale height. I don't eve talk about modern ones. So the brand-new super-quality deck is possible, but it's price will be cosmic. 2019-06-27 20:57 GMT+03:00, Kevin Fetner via Naktalk : > We talked/argued about this at length a few yrs ago.

Interestingly, it’s a slightly different story with R2R. One company is refurbishing old Tascam machines, and there was talk of Revox making new play-only R2Rs (I don’t know if it’s actually happened yet). Certainly, one can now buy 15” (!!) tapes of certain works that have been copied from the original masters. But you’ll pay hundreds of dollars per tape! Sure, I guess the sound quality will be unequalled. But you can’t miss what you’ve never heard, so I guess we can learn to be happy with much less. And, heaven forbid, even digital can sound good enough. -------------- next part -------------- An HTML attachment was scrubbed...

When adjusting precisely the azimuth in one direction, the azimuth of the other direction CANNOT be correct otherwise this would mean that the directionnal azimuth error does not exist ; this is why the Dragon was created ! So, I would say that when you calibrate the azimuth on the Dragon, you have to find a compromise in the azimuth for both sides, that is never perfect for any side ! I think some big figures here will correct me if I am not right.

When I follow the procedures in the service manual it says I should do the phase adjustment within 10 seconds. For the forward direction I can do this (I can reach only 0.095V instead of zero). For the reverse direction volt meter continuously fluctuates and impossible to make any adjustment. So I ve checked the left and right channels. What I saw is forward direction the waves are overlapping, for the reverse not. Since I flip the test cassette for the reverse direction,signal path should more or less match with the head tracks. I know the philosophy is dividing the right track into two and make comparison with each other.

When adjusting precisely the azimuth in one direction, the azimuth of the other direction CANNOT be correct otherwise this would mean that the directionnal azimuth error does not exist ; this is why the Dragon was created ! So, I would say that when you calibrate the azimuth on the Dragon, you have to find a compromise in the azimuth for both sides, that is never perfect for any side ! I think some big figures here will correct me if I am not right.

What I did is actually the same but when I flip the cassette for reverse adjustment while CN-5 is disconnected DC voltmeter fluctuating so I cannot make any adjustment. If I connect the CN-5 to see what happens, then azimuth motor swings both side and doesn’t stabilize at any point. So by the help of a scopemeter the L&R channels sine waves which were having phase difference overlapped adjusting the VR702. When the waves are overlapped the pointer stays stabilized 2-3mm left of the center mark. Now forward playback pointer stops at the center position, matching with the mark. For the reverse playback stays 3mm left of the mark. With this adjustment I didn’t do any adjustment by VR701 I overlapped the both channel signals using scopemeter while cn-5 is disconnected.

The specs are pretty close indeed; the decks however use the part with the A suffix due to the current gain required to drive the motor.
