Subject: [naktalk] LED conversion for 600 series
Message-ID: <9692ED94-1B05-4ED0-BA10-3399EB9CC3BF@gmail.com>

I have a 600 Series system in a rack and one by one the lights have failed again. I live near NYC. Is there anybody nearby who could handle the conversion to LED lights?They should be warm and not too bright, like the originals.

 Hello Naks,New to the forum, but lifelong Nak fan.  Glad to be on the site.  I had some difficulties with the mail program, so this may not work, but we'll see if it does.  I have a question for the group.I'm servicing some 480 decks, and one of the things that I have not done as yet is to pull off the reel hubs and check for proper lubrication.  I usually take out the whole transport assembly and take it apart.  These are the Nak classic transport.  While I'm replacing the belts and cleaning and lubing the transport cam mechanism, I try to relube other moving parts as well.  I do clean and lightly lube the capstan shafts with light machine oil, and when I replace pinch rollers I also clean the old hardened grease off those shafts and lube with fresh lithium grease.  As for the reel hubs, it might seem like a silly question, but how do those reel hubs come off of their shafts?  It looks like the tiny cap at the end of the reel hub shaft is simply pressed on, but they are really tight and are hard to remove.  Is the right way to simply pull them off?  More importantly, is there any critical element in how to press them back on properly?  It seems a bit difficult to do and apply enough pressure to get the cap on all the way and bottom out on the shaft.Thanks in advance,  Tom

I tried to set the record head height per SM and couldn't do it .  TP102 was unresponsive  or real low (#43) on the meter with head adjustment  whereas TP 202(#42) was high and there was some control with the head adjust. This circuit might be the problem and there is always those Dolby chips ua7300PC.  I did check the head with the diode function on my meter and both side measured the same . I haven't given up ,any ideas ?

The new Nichicon KL 6.8uf worked fine .

I did check the decks record function before recapping but only by the decks meters ,I didn't playback the recorded tape. The meters work on the incoming signal and playback. I rechecked all the caps, cleaned the switches a couple of times . The Record/ Play switch is clean.

Thanks Axe for taking the time to look at the schematic , I should have posted more info.  That 6.8uf  value made me question upping the value . I think I'll m try a 3.3uf x 2 or 4.7uf + 2.2uf   in parallel

If I understand correctly that circuit, the role of those capacitors is to compensate for the sluggishness of the needles on the analog meters (due to internal friction). The capacitors will very briefly increase the amplitude of the voltage presented to the meters after a sudden increase of the input signal, making the signal peaks easier to see and the needles look more responsive.

 

Hard to tell what exactly increasing their value from 6.8 uF to 10 uF would do. I predict the needles will move a bit slower and the peaks of the signal might also be shown as a little bit lower with 10 uF instead of 6.8 uf. By how much? Well, you’ll tell us. 

 

Of course, there will be no audible difference, as the C150 and C250 are not in the audio signal path sent to the output of the deck. Also, of course, there might be a tiny audible difference on recordings whose levels were adjusted by the operator based on what was shown on the less responsive meters at the time of recording (the peaks on the meters might be higher than they appear). 

 

Good luck, 

Axe

Hi Calman46

 

The first thing I would check would be the bias oscillator. Do you have a CRO (Oscilloscope) or a DVM? If possible check to see if the bias oscillator is oscillating at about 105KHz, and check the output amplitude. In the record mode, there should be a large nicely sinusoidal signal at the bias oscillator output with an amplitude of about 26Vrms or about 74V Pk-Pk. The two 4.7nF orange caps in the bias oscillator account for a large percentage of record problems in a 481. If you fitted new ones (2 X 4.7nF polypropylene) when you recapped, that shouldn't be a problem, but maybe just make sure the solder joints are good. 

 

If the bias oscillator isn't the problem, and you’ve said Play is OK, the alignment of the Record Head would be another key reason for record problems in your 481. Not to mention a few dozen other possibilities, but try the bias oscillator first.

 

Regards 

 

John Gipps

Hi john , I checked the bias oscillator with a function generator and it's there 105KHz. I'll look at it with the o-scope and check those 4.7nf caps

Using a 100MHz o-scope , I can see the sine wave and the digital read out is , 105KHz , 15.4vAC, 43.5 VPP , measurements  taken from pin #24  right off the oscillator. The 4.7nF caps look good .

Message-ID: <7CE03205-DF32-416B-B853-7EF71935D960@me.com>

Hi all

I’ve got a Nak 1000 that I rescued from a local vintage shop where I don’t know how long it would have sat had I not stumbled upon it. I’ve done a clean up, lubrication, checked belts, etc. It’s in good shape generally. 

What I find is that the worst aging is in adhesive and foam. For adhesive I had to remove the black metal face from the front panel since the adhesive had dried and the two metal plates were separating. For the foam the issue was the cassette “lid”.

The cassette lid (the faux leather door) was in poor shape - the foam inside had deteriorated somewhat and the vinyl had pretty severe rippling. It didn’t look nice and tidy as original and not like other decks I’ve seen. I’ve done a DIY repair for now, creating a new foam layer underneath the vinyl. But getting it cleanly glued back into the plastic housing perfectly as original is pretty tricky. It’s pretty good, but not perfect.

So, wondering if anyone has an unused Cassette Lid Assembly, part number HA-3570, as shown in the Service Manual diagram 5.1 - Mechanism Assembly, and parts list (pp 22, 23). I think the whole piece will be in great shape if I swap out the door for one that is closer to original condition.

Cheers
Jason

Hi Tom, Just pull the tiny end caps straight up gently and firmly and with
enough pressure that they don’t come off in. Rush and fly off as there is
spring underneath and they are a pain to find once they fly off and hide on
the floor in the least likely place you will find them beleive me it
happens speaking from experience!:) yes lubricating the metal shaft of the
hubs like those of the capstan is quite important you will notice how fast
the ffwd and rewind time is !! best regards! Ali

Thank you for the advice, Ali!  I already discovered for myself the issue you mention, as there is one of those little springs somewhere in my office room, never to be seen again, most likely.  Is there any magic related to pressing the caps back on?  I don't want to bend or break anything, and it's a little hard to tell if they've bottomed out.  Ideally perhaps a small arbor press would help avoid side loads, but there doesn't seem to be any way to back them properly for a press.  I just used my fingers and pushed as hard as I could.  Best regards,  Tom

I got the deck (Nak 481) to record in all 3 tape types without the distortion but the recorded volume is still too low compared to the source .  I'm having trouble with #8 & #9  on the adjustment chart , the coils don't respond when turned. I have AC millivolt meters on the record head jack , I not sure  if I have them connected correctly though, do I unplug the recorded head ?

Hi john , I checked the bias oscillator with a function generator and it's there 105KHz. I'll look at it with the o-scope and check those 4.7nf caps

Hi Calman46

 

The first thing I would check would be the bias oscillator. Do you have a CRO (Oscilloscope) or a DVM? If possible check to see if the bias oscillator is oscillating at about 105KHz, and check the output amplitude. In the record mode, there should be a large nicely sinusoidal signal at the bias oscillator output with an amplitude of about 26Vrms or about 74V Pk-Pk. The two 4.7nF orange caps in the bias oscillator account for a large percentage of record problems in a 481. If you fitted new ones (2 X 4.7nF polypropylene) when you recapped, that shouldn't be a problem, but maybe just make sure the solder joints are good. 

 

If the bias oscillator isn't the problem, and you’ve said Play is OK, the alignment of the Record Head would be another key reason for record problems in your 481. Not to mention a few dozen other possibilities, but try the bias oscillator first.

 

Regards 

 

John Gipps

The new Nichicon KL 6.8uf worked fine . The deck plays fine but I'm having trouble with record , ZX works but needs tweaking I think (unbalanced R&L), SX and EX , are very weak I can barely hear the recorded signal. I did check the decks record function before recapping but only by the decks meters ,I didn't playback the recorded tape. The meters work on the incoming signal and playback. I rechecked all the caps, cleaned the switches a couple of times . The Record/ Play switch is clean. Everything points to the SX switch ,there is no connections to the actual EX switch it just disengages the other two (ZX,SX). Any suggestions on what the problem could be ?

Sorry its #9 &#10 that  won't adjust and I get different readings off CN5-1 &2, CN5-3&4  if I use a digital bench  AC meter I get 5vAC with input volume maxed. With an analog AC millivolt I next to  nothing  . So L104 (L204), L105 (L205 ) don't  adjust or I have my meters hooked up incorrectly , anybody ?

Hi Jim

Apologies for the delay in replying, and I'm doing a bit of catch-up here. Glad to see you're getting a 105KHz sine wave output from your bias oscillator, but the output level you report seems low. I would have expected more than 15Vrms - more like about 26Vrms at pin 24. So it might be wise for you to backtrack a little, and check to see that you're getting effective erasure, and that the DC Voltages measured in your bias oscillator are somewhere near the values shown on the schematic. 

The main power supply to the bias oscillator should be giving you 24V, and the voltage after R310 and R311 should be about 19V. Usually one of R311 and R310 is shorted - usually it's R310, the 39 Ohm resistor. Check with your fingers to see that the three transistors in the bias oscillator (Q301, Q302, Q303) aren't overheating.

To check erasure, choose a recorded tape you don't mind erasing, and pass it though the machine in the record mode but with no record signal. Rewind, play, and see how well you've erased it.

The things that are most likely to be giving you bad record results are....
1. Incorrect Bias Level for the tape you're recording on.
2. Incorrect Record Level for the tape you're recording on. 
3. Record Head misalignment - Track and Azimuth of the Record Head. 

You need to get these fundamentals right first before spending time on bias trap adjustments, and record head equalisation as mentioned in your later posts.

You've said that playback is quite good, and that indicates that the Play Head Track and Azimuth are probably somewhere near ok. I'm assuming you haven't changed all the bias and record level settings - they must have been somewhere near appropriate previously. So hopefully, record level and bias, while not being optimal, should still be workable.

So make sure the bias oscillator really is healthy, and then try adjustment of Record Head Track. You can adjust this so as to maximise the play back level of a low frequency high amplitude recording that you make - eg 400Hz at 0dB record level.

Good luck Jim

Regards

John

Using a 100MHz o-scope , I can see the sine wave and the digital read out is , 105KHz , 15.4vAC, 43.5 VPP , measurements  taken from pin #24  right off the oscillator. The 4.7nF caps look good .

Hi Jim

Just a quick note here. 

As in my previous response, forget about bias trap and record EQ adjustments for the moment. While these do matter, they won't be responsible for the low record levels you're getting. How low are the record levels you're getting?

I got the deck (Nak 481) to record in all 3 tape types without the distortion but the recorded volume is still too low compared to the source .  I'm having trouble with #8 & #9  on the adjustment chart , the coils don't respond when turned. I have AC millivolt meters on the record head jack , I not sure  if I have them connected correctly though, do I unplug the recorded head ?

The recorded levels are real low . I can barely hear it and I have to have the record level maxed out . It was better yesterday at lease I could hear  it .

Ok  the deck is recording  but I to have the record level in the red on VU (+7)   and it plays back at -10db on EX(and a little distorted ) and around 0db on ZX but clear . I'll try SX next

Hi Jim

Apologies for the delay in replying, and I'm doing a bit of catch-up here. Glad to see you're getting a 105KHz sine wave output from your bias oscillator, but the output level you report seems low. I would have expected more than 15Vrms - more like about 26Vrms at pin 24. So it might be wise for you to backtrack a little, and check to see that you're getting effective erasure, and that the DC Voltages measured in your bias oscillator are somewhere near the values shown on the schematic. 

The main power supply to the bias oscillator should be giving you 24V, and the voltage after R310 and R311 should be about 19V. Usually one of R311 and R310 is shorted - usually it's R310, the 39 Ohm resistor. Check with your fingers to see that the three transistors in the bias oscillator (Q301, Q302, Q303) aren't overheating.

To check erasure, choose a recorded tape you don't mind erasing, and pass it though the machine in the record mode but with no record signal. Rewind, play, and see how well you've erased it.

The things that are most likely to be giving you bad record results are....
1. Incorrect Bias Level for the tape you're recording on.
2. Incorrect Record Level for the tape you're recording on. 
3. Record Head misalignment - Track and Azimuth of the Record Head. 

You need to get these fundamentals right first before spending time on bias trap adjustments, and record head equalisation as mentioned in your later posts.

I'm assuming you haven't changed all the bias and record level settings - they must have been somewhere near appropriate previously.

Hi John ,  I  went back to pin#24 ,  I have 105KHz , 21VAC,   59.6VPP .   I have 23.32vdc  the bias voltage at IC401   and 17.08vdc at R311 and R301 junction . The voltages are low but not by much. Q301-Q303 are cool and no crazy voltages on them. I was having a problem setting the record height and azimuth (AC millivolt meters on #42 &#43) . So I adjusted the bias and record level while the deck was recording  and watching the AC millivolt meters .I got one side record at 0db and plays back also at 0db, but the record level is full CCW . The other side not so good the signal is fluctuating . I tried to steady the signal with the bias and it helped a little but the AC millivolt meter needle is swaying back and forth . Do you think its tape and head contact ?  I will check the tape path also . Thanks for your help John , I really appreciated it

Hi all,

I have been reading with interest the posts on a 481. Since I have a 481Z I thought I'd ask a couple of questions. The deck's been playing well up to now but recently I've noticed the playback motor doesn't always  stop when the transport is stopped. In other words the capstans are still moving when the cassette door is open and the playback is stopped. In the 480 series I understand the motors don't move in the stop mode unlike in the 580 series or other later decks. It also has an occasional other problem not sure if it's related. The other day while I put a cassette in to play the record light came on and off even though tabs on the cassette had been already removed. I stopped the play but somehow parts of the cassette was erased. Quite irritating. I then put in a blank tape with its tabs intact and kept playing and stopping several times, putting it in the record mode on and off and it has not done it since although the capstan motor still doesn't want to stop on occasions when everything is off. Any ideas? Thanks

Peter

Ok I shorted R310 (it wasn't  originally ) and I now have 18.6v @ R311 just like the schematic . The erase head is working .  I'm looking at the head block Its not engaging completely . This could be it why head adjustment is not working correctly , it only seems to effect one side .  My first Nak repair ,learning a lot .

You need to get these fundamentals right first before spending time on bias trap adjustments, and record head equalisation as mentioned in your later posts.

You've said that playback is quite good, and that indicates that the Play Head Track and Azimuth are probably somewhere near ok. I'm assuming you haven't changed all the bias and record level settings - they must have been somewhere near appropriate previously. So hopefully, record level and bias, while not being optimal, should still be workable.

So make sure the bias oscillator really is healthy, and then try adjustment of Record Head Track. You can adjust this so as to maximise the play back level of a low frequency high amplitude recording that you make - eg 400Hz at 0dB record level.

Good luck Jim

John

Using a 100MHz o-scope , I can see the sine wave and the digital read out is , 105KHz , 15.4vAC, 43.5 VPP , measurements  taken from pin #24  right off the oscillator. The 4.7nF caps look good .

Hi Peter, when you hit the stop button it doesn't stop ? or when auto stop ,
stops the transport ?  . I would work the record switch lever for the other
problem dirty switches ?  maybe both problems

Hi all,

 

I have been reading with interest the posts on a 481. Since I have a 481Z I
thought I'd ask a couple of questions. The deck's been playing well up to
now but recently I've noticed the playback motor doesn't always  stop when
the transport is stopped. In other words the capstans are still moving when
the cassette door is open and the playback is stopped. In the 480 series I
understand the motors don't move in the stop mode unlike in the 580 series
or other later decks. It also has an occasional other problem not sure if
it's related. The other day while I put a cassette in to play the record
light came on and off even though tabs on the cassette had been already
removed. I stopped the play but somehow parts of the cassette was erased.
Quite irritating. I then put in a blank tape with its tabs intact and kept
playing and stopping several times, putting it in the record mode on and off
and it has not done it since although the capstan motor still doesn't want
to stop on occasions when everything is off. Any ideas? Thanks

 

Peter

Got it !  it’s the supply side pinch roller assembly , it moves outward . I had already move this back in but it moved out a little . This time I was able to turn the plastic nut some , hopefully this will hold in place now. I was able to adjust the record head now .Made a test recording with music and it played back loud and clear .  I think I will replace the other trimmers as I already did EX .. I've heard many times that the trim pots can be problematic in vintage gear . Then I'll take a crack at the calibration . Nice sounding deck so far , $5 well spent .Nothing like OJT .

Hi John ,  I  went back to pin#24 ,  I have 105KHz , 21VAC,   59.6VPP .   I have 23.32vdc  the bias voltage at IC401   and 17.08vdc at R311 and R301 junction . The voltages are low but not by much. Q301-Q303 are cool and no crazy voltages on them. I was having a problem setting the record height and azimuth (AC millivolt meters on #42 &#43) . So I adjusted the bias and record level while the deck was recording  and watching the AC millivolt meters .I got one side record at 0db and plays back also at 0db, but the record level is full CCW . The other side not so good the signal is fluctuating . I tried to steady the signal with the bias and it helped a little but the AC millivolt meter needle is swaying back and forth . Do you think its tape and head contact ?  I will check the tape path also . Thanks for your help John , I really appreciated it

Hi Jim

Apologies for the delay in replying, and I'm doing a bit of catch-up here. Glad to see you're getting a 105KHz sine wave output from your bias oscillator, but the output level you report seems low. I would have expected more than 15Vrms - more like about 26Vrms at pin 24. So it might be wise for you to backtrack a little, and check to see that you're getting effective erasure, and that the DC Voltages measured in your bias oscillator are somewhere near the values shown on the schematic. 

The main power supply to the bias oscillator should be giving you 24V, and the voltage after R310 and R311 should be about 19V. Usually one of R311 and R310 is shorted - usually it's R310, the 39 Ohm resistor. Check with your fingers to see that the three transistors in the bias oscillator (Q301, Q302, Q303) aren't overheating.

To check erasure, choose a recorded tape you don't mind erasing, and pass it though the machine in the record mode but with no record signal. Rewind, play, and see how well you've erased it.

The things that are most likely to be giving you bad record results are....
1. Incorrect Bias Level for the tape you're recording on.
2. Incorrect Record Level for the tape you're recording on. 
3. Record Head misalignment - Track and Azimuth of the Record Head. 

You need to get these fundamentals right first before spending time on bias trap adjustments, and record head equalisation as mentioned in your later posts.

You've said that playback is quite good, and that indicates that the Play Head Track and Azimuth are probably somewhere near ok. I'm assuming you haven't changed all the bias and record level settings - they must have been somewhere near appropriate previously. So hopefully, record level and bias, while not being optimal, should still be workable.

Hello my new Nak-loving friends!I recently had the good fortune of acquiring a T100 Audio Analyzer in good condition.  I have been methodically going through it and getting it up to snuff.  I finished recapping all electrolytics and the few orange poly caps the machine had, and resolved some minor functional issues with oscillator frequency fine-tuning and a flickering display.I am now walking through the electrical adjustment guide in the service manual, and have been able to complete all of the procedures to get it fully tuned.  Actually it was not far out of calibration in most respects.  There remains one issue which I think needs attention.When performing the linear-to-log converter output span and zero adjustments I find what seems to be a temperature related drift in the right channel.  I set VR203 for an output value of 2.18v, and the value slowly inches upward over time.  The left channel settles in in a few seconds and doesn't move much after that, but, but the right one just continues to slowly drift, a millivolt at a time.  If I let the machine alone, it does eventually settle, but the moment I make an adjustment it is off again.  I did clean VR203 with deoxit, because the pot seems very twitchy.  It didn't help, and I will replace both of those pots with modern ones as soon as I find some.  I don't think that is what is causing the drift, though.My analog electronics skills are a bit rusty, and I can't say that I ever looked much at log amplifiers, even in the dim past.  I was just wondering if any of the experienced 'sparkies' in the group had any recommendations about what the culprit might be, short of going after it with a can of freeze spray?I would appreciate any guidance on the topic.Best regards,  Tom

Message-ID: <026601d496ed$5c9d1140$15d733c0$@verizon.net>

I'll start a new thread for this.  This 481 has new belts and tire , recapped (orange film & electrolytic ) and new trimmers . The deck now records on all 3  tape type settings . The playback of the recorded material is real  close to the level of the original input . Being this my first NAK repair of this level mistakes were made . I should have had a better plan . I adjusted the trimmers and didn't make note of their original  settings . I realize the SM is not a how-to  manual so I have questions . I ran into a problem when I got to #13 of the adjustment chart. Its setting the 3mV bias and the 30mV record level  . I wasn't sure what  voltage  I was seeing on my AC millivolt meters , and  the playback wasn't right.  So while in record I  adjusted the bias and record level .  I couldn't adjust the record level enough( to get the playback equal to the source) I would need to increase the bias and then adjust the record level  again.  So going from record to play and using  the decks VU's  to dictate to either increase or  decrease the trimmers appeared to work . The input level was set at 0db and the playback on all 3 types is real close to that , by the decks VU's.  I used a Maxell UR tape for all 3 , changing the EQ settings per SM.    I do have other types of tapes , a Nak ZX  reference blank tape to name one. 
So I'm not sure if the bias and  record level is set correctly for the 3 types . Any suggestions ? 

 This 481 is a 3 head deck but it doesn't have a tape/source switch , is that why you can't monitor what you're recording ?  When you listen to a deck recording with a tape/source  switch and in tape mode you're listing to the play head (playing the just recorded signal ) correct ? . On this 481 you hear the input signal when the deck is recording but not from the RH/PBH , that’s why I thought the deck was recording ,before I worked on it.
 I'm  a hobbyist with no  electronic background  and since "they" don't teach this anymore I learn by doing , and asking a whole boat load of questions . I have had good results with Pioneer  decks CT F 1250 ,1000 etc.  Thanks

Increasing the record "bias" will not increase the record "level". Increasing the record bias will eliminate the high frequencies from the recording. Sounds like you have the SM so go in the order of the alignment procedure.
Are you using calibration tapes?
Also the Maxell "UR" tapes are only for general purpose recording. Music on those UR's will only be acceptable at best. I would use a better "normal bias" tape for aligning the "normal" settings.
Without alignment tapes you can adjust bias this way and get pretty good results...
Record from an FM radio NOT tuned to a station with the tuner's muting off so you get only "white noise" Record at -20db then play it back. Adjust the bias so the white noise sounds as close to the same as possible. Please note, important... you can only do this after all the levels are correct! You may have to go over the level and bias adjustment a couple times to get it dialed in. Also with dolby OFF. Make sure the heads are cleaned and demagged.
Of course alignment tapes are the best way to go.

I'll start a new thread for this.  This 481 has new belts and tire , recapped (orange film & electrolytic ) and new trimmers . The deck now records on all 3  tape type settings . The playback of the recorded material is real  close to the level of the original input . Being this my first NAK repair of this level mistakes were made . I should have had a better plan . I adjusted the trimmers and didn't make note of their original  settings . I realize the SM is not a how-to  manual so I have questions . I ran into a problem when I got to #13 of the adjustment chart. Its setting the 3mV bias and the 30mV record level  . I wasn't sure what  voltage  I was seeing on my AC millivolt meters , and  the playback wasn't right.  So while in record I  adjusted the bias and record level .  I couldn't adjust the record level enough( to get the playback equal to the source) I would need to increase the bias and then adjust the record level  again.  So going from record to play and using  the decks VU's  to dictate to either increase or  decrease the trimmers appeared to work . The input level was set at 0db and the playback on all 3 types is real close to that , by the decks VU's.  I used a Maxell UR tape for all 3 , changing the EQ settings per SM.    I do have other types of tapes , a Nak ZX  reference blank tape to name one. 
So I'm not sure if the bias and  record level is set correctly for the 3 types . Any suggestions ? 

 This 481 is a 3 head deck but it doesn't have a tape/source switch , is that why you can't monitor what you're recording ?  When you listen to a deck recording with a tape/source  switch and in tape mode you're listing to the play head (playing the just recorded signal ) correct ? . On this 481 you hear the input signal when the deck is recording but not from the RH/PBH , that’s why I thought the deck was recording ,before I worked on it.
 I'm  a hobbyist with no  electronic background  and since "they" don't teach this anymore I learn by doing , and asking a whole boat load of questions . I have had good results with Pioneer  decks CT F 1250 ,1000 etc.  Thanks

I tried to calibrate each tape type per SM but the readings on the AC millivolt meter for the 3mV were not right . There wasn't enough adjustment on the record trimmers to bring the recorded signal up to 0b .  Adjusting the  bias and record level  and observing the decks VU meters on playback now all 3 tape types  playback at the same output as the original input signal  0db. This is the only way I could get results , I tried the SM steps many times  with no luck . I recorded some music and it plays back just like the original . The NAK ZX  tape I used sounds great , other  tapes Maxell XLII and Sony EF good too .  There is no real time record monitoring so  white noise didn't work for me in this case. I may be able to tweak the bias a little but if I turn the trimmers to much it will affect the record level some . What do you think ?

Hello and Happy Holidays to all,I recently put all new belts, idler and pinch rollers on a Nak 480 deck.  Parts were from what I believe to be reputable sources.  Wow and Flutter weighted, peak and rms as measured by Alex Freed's WFGUI program actually went up by about 50% with the new parts, from what was in before.  Swapping parts back and forth it seems as though most of it is the pinch rollers, which were moderately worn, and the capstan belt seems a moderate contributor as well.  I am surprised by this, but am a bit of a beginner with this stuff.  Do these parts need to break-in in order to get to optimal W&F performance, or is it simply a matter of not being able to match the original Nak spec on rubber parts?Thanks in advance,  Tom

The capstan belt is the most critical part regarding W&F in a Nak 
classic transport.  I have had bad belts from PRB in the past.  The best 
belt I have found so far is one from Fred Marrs. They are a bit pricey 
and can be slow for delivery, but his belt came closest to the original 
belt for performance.  I measure W&F using a Sound Technology 1510, a 
very accurate test set.

You might try "breaking it in" for a few hours, it might improve, but a 
lot relies on the quality of that particular rubber part, it needs to 
have a very consistent thickness, width, friction coefficient and the 
correct material.

Hello, Tom. I cannot say exactly but I don't think they need a
"warm-up". Quality rubber parts should be already in good condition
once you installed them. But there maybe different reasons why you get
heightened W&F like very strict specifications, non-ideal new parts,
wear of other parts in the transport or capstan motor speed issues.

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

If the battery is replaced with a typical coin battery holder, which are typically only two posts, a hole must be drilledin the matching part of the circuit. I install them all the time. If the deck does not lose power, then the battery is totally unnecessary. On the CR-5 especially it does very little. It was not a lot of trouble for Nak because, IIRC, the actual PCB design is identical to the CR-7. I absolutely guarantee that if the soldered in battery is still on the deck, it is shot. I would clip it out at the very least before the battery leaks and corrodes the PCB.

Perry, I home-made a coin battery holder with leads so from now on it can be replaced easier. I have an idler tire on it's way which I hope to get this week. This CR-5 is always plugged into a power strip so unless I lose the mains due to a storm or whatever it will always have power. The power switch is not always on, it just always has the 120 volts AC. I also thought about just eliminating that coin battery completely. Still debating about that.
Thank you. Bob N

Not bad!

Seriously, would someone have a URL where to find a battery holder that 
can be soldered on CR-5&7 on which you could clip a new battery ?

Happy New Year to Naktalkers

Google is a good information source at instances like this. I am not sure
what kind of coin battery there is in the Naka CR5, but I tested with
battery type CR2032:

Or -- just a thought -- you could order the correct replacement solder-in
battery to keep the deck like new.

Keeping it original has been in the back of my mind also but keeping it original is not that important to me. Ease of replacement in the future was what I was thinking. We'll see. Thanks for the part number.Happy new year!Bob N

Hi Willy,

Even did not think it could exist!
Now, this part is in front of my mind...

Thank you to all, that seems to be a good New Year beginning.

All the best
Bernard

Well, after checking, it is only available in the USA...not at Mouser France

I got my new idler tire for this CR-5. I've never done this job, I've only removed the plate to get access to the tire for cleaning.
Holy cow is that new clip small! I can see if it's dropped it may never be found so I guess I'll stand the deck on it's back and think of some way to keep it from falling into the deck or onto the floor.
Hopefully I'll get at it this weekend.
Any hints for what you guys do to keep that clip/washer from running away would be greatly appreciated.
Happy new year all.

Don't take the retainer clip off, just take the rubber tire off from
the idler roller.  I use a small metal pick or small screwdriver.

Martin, I wondered about that and why all the instructions have you taking the entire wheel off? Have you done it this way?

Bob.

i have tried it both ways but found that just removing the entire wheel was easier for me.

It must be added that before removing the entire wheel, you must SUPPORT the assembly or it may break. What I do is (with deck standing up) place some  popsicle sticks cut small, or thick toothpicks behind the assembly cross-wise to support the idler holder. To remove the sticks, i then prick them with a sharp knife to lift them.

I would recommend this support technique even in the other method.

Been there lost that. Put the red permanent marker to it prior to removal.
And then massage a strip of scotch tape over it. Which usually stops it
from launching during removal.

I broke a Dragon idler arm trying to do that. Take the wheel off. 
Fortunately, I had a spare. Now I don't have a spare.

A red sharpie to mark it is a good idea, and for the newbs doing this, cellophane tape, cut in a circle to not overhang the hub will keep it in place. I always remove the hub as well, as working in that tiny space with the tension of the tire is courting a broken idler tire arm. As long as you grasp the tire firmly and hold it steady with no down or up force, then a small sharp screwdriver will easily pierce the tape and get under the washer. The idea is to have a screwdriver small enough that it is sharp but wide enough so that you can twist the blade under the washer and standup stretch the washer over the shaft. The technique is important. Do NOT try to pry the washer using the screwdriver like a lever. That is more likely to break the arm. When you use the blade Twist Method, the pressure is applied at the base of the hub,near the shaft, where it is strongest. The washer will “stand up” under the screwdriver blade and come right off.Once the new tire is on, cut another circle of tape, and use that same screwdriver to push the washer straight down over the shaft, again firmly holding the tire with tape assuring the washer will not pop away. Clean the tire after you are done.

I fully agree. 

Trying to replace the tire in-situ poses the risk of breaking the tiny plastic arm that carries the idler. That's an 
irreparable part that it's practically impossible to obtain a replacement for. 

OTOH, removing the idler carries the risk of losing the tiny washer that secures the idler in place. That's no big 
deal. I find that stuffing the cassette well with a piece of rag before idler removal prevents the disappearance 
of that washer from sight. Never lost it since the only time I did  :-).

Sankyo idler on Nakamichi is very easy. As described use adhesive tape and pull the idler retainer clip of with a small hook, or the entire idler wheel. For reassembly after putting a ned idler rubber on, I first put on the idler wheel and with the retainer on the adhesive tape, sometimes I make a hole in the tape over the retainer centre. Then place the retainer on the aisle? And push down.

 

But idler change on the classic transport, might be much work! Right now I try to reposition the idler wheel on a LX-5 ☹ 

Any GOOD! Instruction to that easy? (try not to cut the wire strips so I can easily slid back on the guides for the two alu covers. (excuse my English if there are some bad spelling)

I fully agree. 

 

Trying to replace the tire in-situ poses the risk of breaking the tiny plastic arm that carries the idler. That's an 

irreparable part that it's practically impossible to obtain a replacement for. 

 

OTOH, removing the idler carries the risk of losing the tiny washer that secures the idler in place. That's no big 

deal. I find that stuffing the cassette well with a piece of rag before idler removal prevents the disappearance 

of that washer from sight. Never lost it since the only time I did  :-).

Don't take the retainer clip off, just take the rubber tire off from
the idler roller.  I use a small metal pick or small screwdriver.

in case of lost washer, a replacement can be made out of thin plastic like from an overhead transparency or one of similar thickness

just cut or punch a small circle or square and pierce a hole in the middle.

worth a try if no spares available.

Hi all, I got it pretty easily. Good light and my reading glasses did the trick. The CR-5 works like a champ again!Thank you everyone for all of your help. Reading everyone's e'mails made me feel comfortable doing this. The little microscopic washer/clip is what worried me.
Happy New Year everyone!

I would like to make available to all Naktalk members a corded Tri-tracer
remote control unit. I bought this several years ago @ a long defunct
dealer in Seattle called Seattle Stereo (if memory serves), when I had a
700 but I never got around to using it and the 700 is long gone (I still
have a CD-1 & a CD 1.5). This remote has been sitting on a shelf in my
equipment rack for ca. 20 years and I'd like to make it available to
someone who can use it.

Thanks in advance.

I have a 700 II. If it is for this deck I’d be interested in yours!
Let me know what you want for it. My email is at the bottom of this message if you’d prefer to talk privately.
Have a great week!

I would like to make available to all Naktalk members a corded Tri-tracer remote control unit. I bought this several years ago @ a long defunct dealer in Seattle called Seattle Stereo (if memory serves), when I had a
700 but I never got around to using it and the 700 is long gone (I still have a CD-1 & a CD 1.5). This remote has been sitting on a shelf in my equipment rack for ca. 20 years and I'd like to make it available to someone who can use it.

Hi, There is a guy on eBay that sells wireless remotes for all Nak decks with a din plug in the rear of the deck. Works great.

Subject: [naktalk] Tri Tracer corded remote.
Message-ID: <CAHEM71fW3xf1OFAW06T1OhgtvwXwifWTJD96WkFQxc2XAgx34A@mail.gmail.com>

To: all interested parties:

Thanks for your interest!

The remote has no part Numbers (nor any other numbers) on it It simply says
"tri tracer remote" on the front and "made in Japan on the rear"

I bought it 20 some odd years ago for a 700 Tri Tracer & as I remember I
tried it with that deck to make sure it worked and never used it again
having moved from the 700 to a ZX9 shortly after. If your deck has a 7 pin
DIN plug on the rear I see no reason why it would not work with your deck.

All of the previous being said I think I have it sold to Rodrigo as he was
the first to contact me.

Best Regards, Arthur

I don't think that is true as I responded first and shortly after it was posted.

Hi Michael,

Unless you emailed directly, you need to look at the NAKtalk January archives to see the message time stamps.  Actually Rodrigo and Perry both have reply messages at 12:50 and 13:51 CET in before your reply message at 17:11 CET.

In any case, any seller, IMO, always reserves right to sell to whomever they wish, many times on basis of private info or decisions not always publicly known or shown to the rest of us unless it is on a selling site with strict rules or restrictions on transactions.

just my 0.02.

Regards,

Bartley Yee
La Habra, CA.

greetings Naktalkers:

Bartley is correct (many thanks Bartley)
Rodrigo's email/offer was the first I received & in fact we already had an
agreement by the time I received another inquiry.

Patty!!, How are you? It's Scott from Coatesville, PA, the town where everyone wears a coat. I hope you are doing well. I have I sold off all my Nak stuff less 1 1000zxl. You have to hold on to something from the past right?
Wishing you well,
Scott

Message-ID: <B31A5D16-DE7C-49F2-869C-6E86CFD274B9@gmail.com>

I will go to Japan in February.

I want to buy the N1000 ZXL CPU connectors who are needed to connect the ZXL Maintenance Instrument
to the CPU.

I am thinking to make two off this M-9057 Instruments.
I found the Schematics to make them inside the original  ZXL Service Manual.

It is made with 27 switches. LED diodes display,and two C-Mos IC´s.
I am planning  to make one of it  to rent it worldwide.

What do you think about that?

I already have the metal Boxes, the unit will be around
4 kilograms.  Very stable, so it will be  easy to ship the unit.
" It is necessary to put the circuit to the desired adjustment condition."
… Nakamichi did write that in the Service Manual.

What to you think ?

Hi Gerhard,
I am intrested in some sets of the connectors.
Is it possible to buy 5 sets from these and deliver the to me? I did not find these connectors on regular places here in europe.
Best regards

Hi Gerhard,
You need that m9057 to calibrate all the internal values of the machine. Without that it is nearly impossible if you ask me.
I recently did a overhaul job on a 1000zxl and because of replacement of many parts the machine did get a complete calibration.
Well if you can find the connectors that would be great . 
I am intrested to buy 5 pieces from each connector you can found there. 
Best regards
Norman

Message-ID: <5A5DBE06.70905@gmail.com>

Dear Naktalkers,

I have a Dragon with the second (from bottom) left LED not shining 
anymore. It has been working for a while then has begun to stop for a 
while, then working again and then defenitely stopped.

I fear it is the LED itself and I guess the display unit is neither 
unobtainable nor reparable
Is it worth swapping the chip driving the first 10 segments to see if it 
chnages anything ?

Thanks
Bernard

This is as I can see from my ZX-9 and Dragon, a little to long for the Dragon? But maybe there are LED indicators from other decks that could be used? Maybe BX-300/MR-1?

No, even that from MR-1 is not the same.

I do agree about the time life of LEDs but I do not understand what can 
be responsible of this "disconnection" except R319 as I have checked the 
soldered joints, and if so, why the "right channel" analogue does work ?

The most likely is that it has built up some oxide or another cause to disconnection between the driver and the LED. The least likely is that there is a semiconductor error in the driver or the LED. Those components usually have an "eternal" life.

Subject: [naktalk] Dragon Pressure Roller Arm Ass'y washers
Message-ID: <5A5F464D.8030909@gmail.com>

Dear Naktalkers,

Following my first mail dealing with Dragon, I was wondering in the SM, 
page 20, describing the washers of the pressure rollers assemblies, what 
does mean "T" in "2mm 0.25T" ?

I have also found that when I insert the thinner washers inside the cage 
as described in the SM, the take-up cage in not fully free to rotate. 
Conversely, when I insert the thicker washers inside the cage (reverse 
of what described in the SM), the cage is indeed free to rotate.

Is there any mistake in the SM ? or the thinner washers do have to go 
inside the roller cage ? Would someone be willing to confirm/comment ?

Thank for guidance
Bernard

Hello Bernard,
 
"T" might stand for Teflon ?? There definetly can be mistakes in the service manual. 
 Are you the same Bernard that sold me the new ZX-9 pinch rollers a few years ago?
 
Cheers,
Rainer

Hello Rainer,

Yes, I am. Are do you evaluate these rollers? However, there are too 
large for the Dragon...!

Another way to ask my question about the thickness of tehse washers 
would be "Does the roller has to have some transverse (from back to 
front on its axe) play into the cage ?". If yes, it makes sense that the 
thinner washers have to go inside. If not, the thicker ones have to go 
inside the cage...

Best
Bernard

Hi Bernard,
Mostly there are three thick and one thinner on the outside where the clip is mounted.
0,023 are thick and 0,011 is thin.
One technican told me that these units are asembled in the factory to get the most narrow gap from the roller and a good movement when mounted.
Because of that not all the washers are the same thickness.
Best regards,
Norman

Bernard, I never got a chance to evaluate those rollers because the 
rubber had deteriorated before I had a chance to install them.

Rainer,
That's strange to me because I have installed lots of them and they are 
really good.
Would you have a picture of how they became ?
I still have some, please send me your adress in order for me to send 
you a new pair
All the best
Bernard

Dear all,

OK, I checked and the second LED has died!
So if someone were to have a spare LED-Meter for Dragon to sell, please 
let me know (see attached picture).

One can always dream...

All the best

Bernard,

Some thoughts...

Are you certain the LED is dead?

Have you examined all the solder joints under magnification?

Have you measured the voltage going to the LED?

Is that a fully-molded assembly or is it a cover over individual LEDs?

While it is possible for an LED to go, there are many less reliable 
links in the chain. Also, depending on how that was manufactured, it 
MIGHT be possible to replace an individual LED.

I know the full module would be ideal, but...

Cheers,

Richard

The most unlikely things sometimes happen. In this case you could almost
say a chance on the million. But I still find it difficult to really
believe. And this LED must have been working correctly before something
strange happened.

Subject: [naktalk] BX-125 Mechanism Issue
Message-ID: <xguy9p5t1xj6vlph9xpbq7uy.1517196301374@email.android.com>

I asked this a few months ago, so I'll send it against and will hopefully get a response.

I recently fixed the idler tire on my Nakamichi BX-125 (a plastic piece behind the tire itself), but in doing so, the mechanism had to be taken apart. I put it all back together, but when I tested it, it acted strangely. The transport mechanism for going up and down doesn't lock into place and just shuffles back and forth. Also, FF and rewind don't do anything. I checked all the wires that I unplugged, so it can't be an electrical thing, right? The transport worked fine before I took the mechanism out; did I misalign something? I didn't end up with any spare parts, so I didn't forget anything. Some guy suggested I switch the wires one one of the motors. That doesn't make any sense to me (I'm not an expert, of course), so I haven't tried it. What do I do? Any idea?

My first impression is that this is related to the control gear. Either the gear has come out of position, or the gear motor has a wire that has come loose from either the solder point on the motor, or from the feed? Side. This has happened to me.

Hi Kyle,

 From that description, sounds like your mode control motor is out of 
sync.. the motor driven mode cam gear set on the back of the mechanism 
isn't working properly. Could be the motor itself sticking, usually is. 
You can manually check by 'assisting' the cam gear set with a finger 
while changing modes. If the deck behaves, then good chance that is it.

Fingers crossed, cheers

Martin

Subject: [naktalk] Question about possible missing resistors on PA-350
	Mobile Amp
Message-ID: <CABXs_0xaJJsp0gZP89PWE2EmiQ+VEHjLcumGhKNrh=n2_p+7PA@mail.gmail.com>

I'm setting up a vintage Nakamichi Mobile Audio system in a project car and
have been performing some Q/A on my components before I "commit" them to
their locations.

I have a Mobile Audio Series PA-350 35w x4 amp that I am using to drive 4
tweeters. The amp appears to have a few issues as the only output is a
pulsating pop every 5 seconds or so. I pulled the lid off and started
checking the state of the grounds when I noticed that two of the resistors
on the D/D converter PCB had solder pad cracks, one actually having popped
out of the hole.

The resistors are the 47Ohm 2w fail-safe resistors on R413 to R420. A
closer inspection indicated that R415 & R417 had cracks, but R416 & R418
were actually missing from the board.

I'm scratching my head on this one because it appears that something was
there from the factory as the pads contain solder, with one end left open.
The PA-350 service manual schematic shows resistors in these locations, so
could this be someone's mod or the result of a technical bulletin?

I'm curious to see if anyone else has encountered missing resistors at this
location. Also, any recommendations of "fail safe" resistors if it turns
out that they are needed?

Thanks,
Alan

The other problem could be corrosion on the 3 leaf switches that the mode
control motor actuates.

Thanks for the tip Martin!

I looked at the entire mode switching mechanism and found that one of the copper pins looks different than the other two. It looks like it was lifted higher than the others and there is a small hole where on the other ones, there is another piece of copper. I don't know what it is, but I think it's the problem. If I hold it down and press play, it starts to play for a few seconds, then stops.

Hi Kyle,

 From that description, sounds like your mode control motor is out of 
sync.. the motor driven mode cam gear set on the back of the mechanism 
isn't working properly. Could be the motor itself sticking, usually is. 
You can manually check by 'assisting' the cam gear set with a finger 
while changing modes. If the deck behaves, then good chance that is it.

Fingers crossed, cheers

Martin

I put it all back together, but when I tested it, it acted strangely. The transport mechanism for going up and down doesn't lock into place and just shuffles back and forth. Also, FF and rewind don't do anything. I checked all the wires that I unplugged, so it can't be an electrical thing, right? The transport worked fine before I took the mechanism out; did I misalign something? I didn't end up with any spare parts, so I didn't forget anything. Some guy suggested I switch the wires one one of the motors. That doesn't make any sense to me (I'm not an expert, of course), so I haven't tried it. What do I do? Any idea?

Hello - 

I am starting a rather large project of transcribing cassettes of rare ('lost') off-air recordings of Beeb programmes.

I need the very best quality digitisations. 

I have just purchased a second-hand but in good condition DR 10 machine, with pressure pad lift-away.

I now need to learn the finer arts of azimuth adjustment and calibration ec.

However it didn't come with any User Manuals. I have searched the web and there are no English versions around. 

Please can someone tell me how or where to obtain one.

Thank you -

Chris B.

Hi, Chris

This is a long shot, and one you may have already tried:  http://stereomanuals.com/

The fellow I have dealt with successfully and will recommend unhesitatingly is at rick.stereomanuals at gmail.com so you might send him an email with a description of your needs.

I wish you good luck!  Any thing more I might be of help with, please email me at penman at twc.com

Hi Chris,

Nakamichi DR-10 is virtually the same as Nakamichi DR-2 and both are internally identical to Nakamichi CD-1.5. 

You can use any of these manuals, available at hifiengine.com (free account required):

Les,

Thanks for the kind words.

As shown in the NAK manuals catalog on my site, I do not have the DR-10
service manual. Also checked my pdf library... no go.

PS.. It's been 9 years now. Time to buy some more manuals  :)

 
 
 
 

Best regards,

The fellow I have dealt with successfully and will recommend unhesitatingly
is at rick.stereomanuals at gmail.com so you might send him an email with a
description of your needs.

I wish you good luck!  Any thing more I might be of help with, please email

Hi Chris, 
I would also advice you to download the manuals  and literature for older decks like the 1000 and Dragon as they have good notes in there that will give you some insight on these topics. The internet in general has discussions around these topics as well. 

The DR10 is a fine machine and I have made and heard many great sounding tapes on it. 

Kind Regards, 
Bala Ganesh

I purchased a second hand DR 10 on eBay. The machine arrived OK. But sans English User Manual.

But thanks to folks here I think I might have tracked one down.

However meanwhile I thought better than nothing so I purchased a French version on eBay. It was clearly described as  "Nakamichi DR8 & DR10. Cassette Deck User's Manual. French Edition. Unused." The image showed a three hole punch set of pages.

It cost £5 plus £3 postage.

It arrived today. It was an old leaflet for the DR 1 / 2 / 3. And the seller does not accept exchanges.

What a scam, What a crock. Am not happy.

The seller also has a German version for sale - let buyers' beware.

https://www.ebay.co.uk/itm/Nakamichi-DR8-DR10-Cassette-Deck-Users-Manual-German-Edition-Unused/263940264772

But what really pi$$es me off is not so much the loss of the cash (less than £10) but the time wasted in attempting to get a refund out of the seller &/or eBay.

But this is a scam. eBay normally reacts on the buyers behalf much strongly that it does otherwise. Have you attempted to complain to sBay? You should, definitely!!!

Hi,
Indeed that is something different, ignorant sellers.
But maybe I missed something but have you tried the DR1/2/3 owners 
manual?

http://download.naks.com/manuals/owners/english/Nak_DR1_2_3_OwnersManual.pdf

It may cover what you need and it is free ;-)

Thank you to all the folks who responded to my enquiry.

I have now obtained the DR10 User Manual from the original seller of the machine I bought.

This has now been scanned and is available for free from this link.

P.S. Please don't try to sell this.

Hi Chris

Thank you.
I don't have any Nakamichi, actually. But I hope to be so lucky one day.

Never give up, Mikkel!  I bought my Nakamichi BX-100 cassette deck at a thrift store for $15.  All it took was a set of belts and cleaning and lubrication, which I did with a bit of help from YouTube.

Now I've been torturing it for the last two years.  Runs like a champ.

I bought a Nakamichi 700 II as in good conditions and working. When I got
It it wouldn’t play one channel. Upset with the seller I resigned myself to going after my tech and have him tell me what had to be done. To make a long story short, it took me seven months, buying an old “corpse” of a Nakamichi 700, get it shipped to Brazil and finally have the  good one fixed. It is doable. You just have to commit to it!
Now it is my joy and pride with my other decks The ZX-7, the Zx660 and one still waiting for parts an RX202.

Problems Digitising Cassettes.

I guess this is a project known by thousands maybe millions. However I am running up against problems. Remounting a spool of tap into another shell is easy enough. So too is reattaching lead in / out tape - 3M sticky tape is ideal, using a sharp pair of scissors to trim any overlap.

But the real problem is the actual playing of the cassette tapes.

I use iMic and Behringer devices for the actual digitisation, capturing with Audacity. I then do a Save As... in WAV, FLAC and MP3 (320 kbps) formats.

I have a variety of double cassette decks - all relatively brand new. They have auto-reverse and switch from the first cassette tape to the second automatically.

I always clean the heads manually first, then run a head cleaning cassette, before mounting the cassettes. The cassettes are then rewound forwards and backwards to even up the tape layers.

I have to assume that the read head azimuth settings are OK. I have no way to adjust them. 

So far so good.

BUT the digisations are far from perfect.  

The first side of cassette one is nice and clear but the sound gets a little 'muddy' (loss of clarity and treble) towards the end of that side. The cassette then reverses direction and the 'muddiness' becomes more pronounced.

This effect is repeated when its the turn of the second cassette.

Sometimes when I'm busy after the second cassette has run its course, the first cassette starts up again. This time the recording has lost all treble, and the digitised recording s all but unlistenable. 

This is driving me mad, and has wasted so much time. But it indicates a serious sticky-shed issue, likely exacerbated by the cassette pressure pad forcing contact onto the read head.

Now I have bought a second hand Nakamichi DR 10. This has one difference to the above decks. It has a cassette pressure pad lift-up device, so that the tape passes across the read head passes across with very little pressure. Hopefully this will keep the sticky-shed to a minimum.

What I do find strange is that others maybe with even simpler tape players manage to digitise their cassettes with no reported quality issues.

CJB ,Unless I'm missing something here.....back in the day there were really no quality double cassette decks out there that I know of.....cassette bootleggers used slave decks that ran off of source decks. If you used a well maintained/well sorted Nak BX-300 just for this purpose, for example, I think you'd do well. No sense buying a more high-end Nak just to digitize a bunch of tapes....unless you have a buyer to sell to afterward.

But I must agree, and risk being ignored.  One cannot alter physics, no matter how many small animals we sacrifice or how loudly we chant.

CJB ,

Unless I'm missing something here.....back in the day there were really no quality double cassette decks out there that I know of.....cassette bootleggers used slave decks that ran off of source decks. If you used a well maintained/well sorted Nak BX-300 just for this purpose, for example, I think you'd do well. No sense buying a more high-end Nak just to digitize a bunch of tapes....unless you have a buyer to sell to afterward.

Nothing for sale. The project is the common one of digitising ancient cassettes - in our case off-air recordings of radio programmes that have been wiped or junked by the Beeb long ago. All self-financed.

We have discovered many recordings that we have the Beeb no longer has in its archives (nor the BLSA) and these were offered back to them - they declined or ignored us - their loss.

We need the best possible playback from the cassettes many of which are over 60 years old. We aren't remotely interested in recording anything to tape. Playback is for digitisation ony.

It is the poor playback sticky-shed issue that's the problem - likely exacerbated by each cassette's pressure pads on the cassette machine's read heads.

We have tried using dual auto-reverse playback devices - this being to simply process two cassettes at a time. However the deteriorating quality of the playback on the dual machines that we have tried using has been an issue.

Our interest in Nak machines is that they have a pressure pad lift device.

Unfortunately the machine we have is a DR 10 - which plays single cassettes at a time. We'd love a Dragon but cannot justify the expense especially since this is a self-financing hobby and the Beeb isn't interested in what we are doing.

I've never heard of anyone baking cassette tapes...not saying it can't be done like their reel to reel bretherin....but I wonder how the shell would hold up with the continued heat put to it? 

Also, I wasn't talking about selling the tapes, I meant buying a top machine like the Dragon you mention, only to sell it after you're finished......to get your money back from your purchase. You should be able to sell a well sorted out Dragon on eBay for what you paid for it.....especially if you make the buyers aware of what you did with it. Again, you're going down a rabbit hole with the dual cassette machines and quality for this project. 

Reel to reelers have also used NuFinish with remarkable success on the tapes with SSS. Be harder to do with a cassette, but possible and would not require any heat. Tons have been written about NuFinish and SSS tapes....Google it. If you can stabilize the tape, then you can use a lesser machine like the BX-300. You can't make a better product than what you have, i.e., if the recordings are ordinary, they will remain so. But you should be able to preserve what you have in quality once you stabilize the tape.
If you don't have the time to copy one cassette to another, then you'd have to set up a slave operation as the bootleggers did with multiple machines.

After some quiet tapeless period i decided to take my ZX-7 from the 
shelf and turn it on..
First problem, cam belt, egg shape does not work, so replaced it.
Second it plays slow, very sloooow, but plays. I suspect the 1999 
original Nak belt will be streteched too much so needs replacing.
Anyone has good experience with sellers other then Marrs? There are 
several affordable options, which one do you (eropean) guys prefer?
Also the compartment light is shot, i will have to look for something 
12V/60mA or similar and shape..

When pressing play, the transport goes up (but not the front/right roller) and the left capstan engages with the pinch roller and
the Cassette plays for almost one second and then the transport goes down into stop mode.

When pressing FF or REW, cassette spins for almost one second and then stops.

Seeking advice first as this is a 'minty' looking deck which has probably had very little use.

hi there


The capstan rollers that engage with the capstan spindles use a grease 
that with time gets thick . they will need to be removed and cleaned 
regreased and reinstalled . not for the faint hearted


You need gauges to set back up the guides /rollers . so be careful


regards John

It may need an auto shut off lamp.  It is a small incandescent lamp in
the transport located just behind the tranport control buttons.  You
may need to remove the front panel to access it.

It is a small 12v 25ma lamp.  I have found suitable replacements at wjoe.com.

Good luck.

Seven months after the digital couter of my Nak zx7suddenly stop/freezed on"0000",I decided to check it again. For my suprise the counter worked and the sound was very good. But only for 2-3 minutes. Then it stopped and return itself to 0000 again.
I replaced  the small electrolytic 47uF 10v on counter PCB,but it did not change anything.Now I can't calibrate the azimuth. When I press the start azimuth  button the cassette start running,but the 2 green lights did not light on and couner remain on 0000. I checked the level and bias calibratio.They work on "source "position only.The deck records pretty good without calibration, and the sound of playing back recorded cassettes is very good  to my ears.I will apreciate any help. The deck is very clean. Maybe it was used very little .Vesselin.Yahoo Mail on Android

If I understand correctly that circuit, the role of those capacitors is to compensate for the sluggishness of the needles on the analog meters (due to internal friction). The capacitors will very briefly increase the amplitude of the voltage presented to the meters after a sudden increase of the input signal, making the signal peaks easier to see and the needles look more responsive.

Hard to tell what exactly increasing their value from 6.8 uF to 10 uF would do. I predict the needles will move a bit slower and the peaks of the signal might also be shown as a little bit lower with 10 uF instead of 6.8 uf. By how much? Well, you’ll tell us. 

Of course, there will be no audible difference, as the C150 and C250 are not in the audio signal path sent to the output of the deck. Also, of course, there might be a tiny audible difference on recordings whose levels were adjusted by the operator based on what was shown on the less responsive meters at the time of recording (the peaks on the meters might be higher than they appear). 

Good luck, 
Axe

Thanks Axe for taking the time to look at the schematic , I should have posted more info.  That 6.8uf  value made me question upping the value . I think I'll m try a 3.3uf x 2 or 4.7uf + 2.2uf   in parallel

Those caps do appear to be ballistics compensation for the meters, to
compensate for mechanical inertia and friction.  The meters might
"bounce up" a bit more before they settle with a 10uf cap in place of
6.8uf.

These little component testers are pretty cheap and reasonably
accurate.  I would test the cap for ESR and value, it may still be
good, on the other hand, they are about 40 years old now.

You’re welcome. Sure, you can do that, but be aware that 6.8 uF is a standard value. Not sure where you are, but it’s in stock at Mouser (USA). For instance, this one (you might want to double check it fits):

Hello calman46

C150 and C250 are capacitors in the L and R meter amplifiers of a 481 or 482, and as such, make no contribution to the sonic properties of those decks.

If they are defective, changing them from 6.8uF to 10uF is ok, the meters will continue to work, except that you'll change the ballistic properties of the meters just a little. If they are not defective, I can't see the point of changing them at all, especially as you seem to not have the correct values at hand. In fact, even if you did have the correct value at hand, I can't see the point in changing them. I belong to the school of thought that believes that unless parts are defective, or have a poor track record as regards reliability (eg many of the orange cap values), that there's no rational reason to replace them. 

Regards

John Gipps

My rational reason is these caps are nearly 40 years old  and you just don't know how stable they are . Capacitors are better now than they were 20,30, 40 years old and they really make this vintage gear perform . You should hear what you're missing .

Hi calman46

They are metallised polypropylene. If you want to use good quality film capacitors to replace orange caps and other film capacitors in your 481, the most perfect caps are polystyrene. Of the commonly available capacitors, polystyrene have the lowest dissipation factor and are closest to being ideal capacitors. Second to polystyrene are polypropylene. Polyester capacitors are lower down the food chain, and are sometimes sold as "greencaps". You can probably source polypropylene more easily than polystyrene, and these would be a good choice. Nakamichi would have chosen the polypropylene orange caps with the best intentions for their sonic quality, but it seems in hindsight that they might have chosen a poor make of polypropylene caps.

John Gipps

Hi calman46


Even though the electrolytics in a 480 series deck are approaching 40 years old, most of them are in good serviceable condition. There's no doubt that the values of capacitance and ESR of electrolytics are less stable than those of film capacitors, but having worked on a huge number of Nakamichi decks over many decades, I can tell you that only a very small number of electrolytics in them actually cause problems, or cause degradation of audio quality.

My comments regarding recapping should be seen as a comment to NakTalkers in general. My reply to you re C150 and C250 was because I thought maybe you hadn't realised that these caps were in a meter circuit, where you definitely "won't hear what you're missing". Having been in the audio industry for much of my life, I'm very aware that there are enthusiasts who recap and rechip, and replace power supply diodes with Shottkys etc etc. The readership of NalkTalk surely ranges from people who are interested in hifi but are not much into electronics, to people who are professionals in the industry and are hifi and electronic experts. While there is often discussion about recapping and other similar practices, there is rarely a dissenting view expressed. Those who aren't into electronics could be forgiven for forming the view that every bit of audio equipment benefits from recapping etc. My experience with customers who have recapped their decks, or who have unwittingly bought a recapped deck, is that many of those decks have been converted to unreliable junk in the process. While some people can desolder and remove components beautifully, and then replace them with well-chosen and superior parts and solder them in beautifully, I find that this is rare. In recapping a Nakamichi deck, many dozens of parts are removed and replaced. When dozens of parts are replaced there is a good chance that problems will be experienced in those decks subsequently. I know this to be the case because I've received many such units for repair from customers over the years.

I hope this email sparks some lively discussion in the NakTalk community. I'd be very interested to hear what people think on this subject.

Regards

John Gipps

Hello Naks, I am recapping a 481 deck and there two 6.8uf caps C150 & C250
.Can I up value to 10uf ? thanks

I don't have near the experience you do John, but totally agree with your point of view on this, :)
Even times when it is justified to replace a number of caps it would be better to replace them in multiple passes confirming that results are as expected between passes.
Cheers,

Hi calman46


Even though the electrolytics in a 480 series deck are approaching 40 years old, most of them are in good serviceable condition. There's no doubt that the values of capacitance and ESR of electrolytics are less stable than those of film capacitors, but having worked on a huge number of Nakamichi decks over many decades, I can tell you that only a very small number of electrolytics in them actually cause problems, or cause degradation of audio quality.

My comments regarding recapping should be seen as a comment to NakTalkers in general. My reply to you re C150 and C250 was because I thought maybe you hadn't realised that these caps were in a meter circuit, where you definitely "won't hear what you're missing". Having been in the audio industry for much of my life, I'm very aware that there are enthusiasts who recap and rechip, and replace power supply diodes with Shottkys etc etc. The readership of NalkTalk surely ranges from people who are interested in hifi but are not much into electronics, to people who are professionals in the industry and are hifi and electronic experts. While there is often discussion about recapping and other similar practices, there is rarely a dissenting view expressed. Those who aren't into electronics could be forgiven for forming the view that every bit of audio equipment benefits from recapping etc. My experience with customers who have recapped their decks, or who have unwittingly bought a recapped deck, is that many of those decks have been converted to unreliable junk in the process. While some people can desolder and remove components beautifully, and then replace them with well-chosen and superior parts and solder them in beautifully, I find that this is rare. In recapping a Nakamichi deck, many dozens of parts are removed and replaced. When dozens of parts are replaced there is a good chance that problems will be experienced in those decks subsequently. I know this to be the case because I've received many such units for repair from customers over the years.

I hope this email sparks some lively discussion in the NakTalk community. I'd be very interested to hear what people think on this subject.

My rational reason is these caps are nearly 40 years old  and you just don't know how stable they are . Capacitors are better now than they were 20,30, 40 years old and they really make this vintage gear perform . You should hear what you're missing .

Hello calman46

C150 and C250 are capacitors in the L and R meter amplifiers of a 481 or 482, and as such, make no contribution to the sonic properties of those decks.

If they are defective, changing them from 6.8uF to 10uF is ok, the meters will continue to work, except that you'll change the ballistic properties of the meters just a little. If they are not defective, I can't see the point of changing them at all, especially as you seem to not have the correct values at hand. In fact, even if you did have the correct value at hand, I can't see the point in changing them. I belong to the school of thought that believes that unless parts are defective, or have a poor track record as regards reliability (eg many of the orange cap values), that there's no rational reason to replace them.

Both are not FF, REW, or Playing all the way thru a 90 minute cassette side.
What's the problem ?

Hi everyone .

Having fully replaced all Orange caps and all electolytics in my 680zx , 
I find  it slightly more detailed and sweeter .

I used pretty good caps through out but did not use crazy size caps 
where the orange drops had been . I did replace all the 1uf caps    that 
where electo caps with good film polyester.

The sonic signature has changed but The 680zx is open and sweet with 
great bass

The new Nichicon KL 6.8uf worked fine . The deck plays fine but I'm having trouble with record , ZX works but needs tweaking I think (unbalanced R&L), SX and EX , are very weak I can barely hear the recorded signal. I did check the decks record function before recapping but only by the decks meters ,I didn't playback the recorded tape. The meters work on the incoming signal and playback. I rechecked all the caps, cleaned the switches a couple of times . The Record/ Play switch is clean. Everything points to the SX switch ,there is no connections to the actual EX switch it just disengages the other two (ZX,SX). Any suggestions on what the problem could be ?

If I understand correctly that circuit, the role of those capacitors is to compensate for the sluggishness of the needles on the analog meters (due to internal friction). The capacitors will very briefly increase the amplitude of the voltage presented to the meters after a sudden increase of the input signal, making the signal peaks easier to see and the needles look more responsive.

 

Hard to tell what exactly increasing their value from 6.8 uF to 10 uF would do. I predict the needles will move a bit slower and the peaks of the signal might also be shown as a little bit lower with 10 uF instead of 6.8 uf. By how much? Well, you’ll tell us. 

 

Of course, there will be no audible difference, as the C150 and C250 are not in the audio signal path sent to the output of the deck. Also, of course, there might be a tiny audible difference on recordings whose levels were adjusted by the operator based on what was shown on the less responsive meters at the time of recording (the peaks on the meters might be higher than they appear). 

 

Good luck, 

Axe

Message-ID: <5A742E40.2030101@gmail.com>

Dear Naktalkers,

Sorry to bother again but I have now a strange "phenomenon" on a 
RX-505E. All the transport has been rejuvanated and calibrated.

During the process of tuning the azimuth, I noticed that the rigth 
channel level was much lower than the left one on the T-100 while the 
led-meter of the deck indicated equal levels of both channels.

I plugged in my headphones and verified that indeed, I had almost 
nothing on the rigth channel.
However, when I unpluged the rigth RCA from the back of the deck, 
everything became "normal" that is the rigth level was back. I could 
verify this by connecting the output of the headphones to the T-100: 
both levels were equal.
And of course, I could repeat this on and on.

I changed the RCA plate : no change! However, when I remove the ground 
ring of the RCA plate that is screwed to the back of the deck, 
everything is OK in PLAY mode (I do have this phenomenon but in STOP 
mode, I can hear a quite significant ground noise in the headphones.)

I checked the 4 transistors and the 2 BP caps of the VR PCB: OK.
The OUTPUT VR must be OK since it works well for the headphones.

I checked on the way from the PB head down to the RCA plate and did not 
notice any wire in bad shape.

Any clue where to look ?

Best whishes
Bernard

Hi, Bernard,

These problems are so annoying!

If you unplugged the right RCA and the level came back, my first 
assumption would be the problem is external to the Nak.

Is the shell of the RCA jack actually grounded to the deck? If it is 
not, try a clip lead or a piece of wire and connect the shell of the 
right RCA jack to the shell of the left RCA jack. If the level goes 
away, then there is an internal problem with the Nak's output wiring. 
Also try Right RCA shell to a bare metal place on the deck (paint is 
your enemy here, it's an insulator).

The above test will let you know if the right RCA jack is miswired (hot 
and shield flipped) which could provide these symptoms.

I would also use a multitester on ohms/continuity and look for shorts in 
the external cable. Also try plugging in the external cable backwards 
L->R and R->L. Does the problem still happen? Does it stay in the right 
channel or does it move?

The only other thing that I can think of at the moment is that if it 
happens only on the right channel there is a short circuit at the RCA 
jack in the Nak that is being activated somehow by the insertion of the 
RCA plug. It might be a fine wire or solder splash.

Beyond that, there could be some issues with the output mute circuit if 
it's anything like the Dragon (which is the only Nak I know details on), 
but I think you'll get some good clues performing the above simple tests.

Cheers,

Richard

If I understand correctly you lose the audio when the output cable is plugged in. My guess is the cable has a short which is shorting out that channel when plugged in. When you removed the ground ring you also removed the short. Again, a guess.Bob N

Emne: 482 does not react on commands

 

I have changed belts and idler on my 482 after buying it as a repair object.

 

When pressing play, FF, or record, nothing happens. Rew. gives a short
reaction (starts, but stops in a second)

 

I also have a 482Z, so to check if there were any transport faults, I
removed the transport from the 482 and connected it to the Z version. All
well, so no transport fault.

 

Then there should be a problem in the power supply line (main pcb or control
pcb)?

 

But where do I start measuring?

 

I´m not good at reading such from the service manual. So suggestions please.

Yes, but I did swap the cable of the RCA to rule it out : same problem 
whatever cable is used.
Same with the RCA plate: I had a spare one that I installed: no improvment.

I think that effectively, when I plug a RCA in, I create a sort but the 
latter is localized inside the deck.

 Hi Bernard

I get confused when you write about "ground noise" and "RCA plate". Do you
mean an RCA connector? Chassis connector? but what means with "a
significant ground noise"?

I mean the plastic plate that contains the 4 RCA connectors, and 
maintained to the back panel by two screws, one of them maintaining a 
ring pinched between the chassis and the plastic plate to put the ground 
part of the RCA to....ground.

"signifcanat ground noise" means that clearly this noise is heard at a 
too high level, as compared for exemple with another deck

Hi Bernard,

Here are the steps I performed on my rx-505 to get rid of the AC humming 
problem, which I posted cople of years ago:

Removed 3 screws from power supply board (heatsink) from the chassis.
Cleaned them up (remove any corrosion) and tighten back.

Tighten down all screws holding the heatsink on the power supply board.

Clean the oxidization on the ring connected to ground wire (on one of
the heatsink screws)

Clean the grounding ring at the audio in/out connector.

I also removed the dolby card and cleaned its connectors, but this step
probably does not matter.


Hope this helps,
_Fuad

OK, I will try this but I think that the problem could come from a 
"mute" problem which is actually activated by plugging in a RCA in the 
rigth output channel.

This happens whatever the cable employed, and with or without an extra 
cable to make sure the back RCA plate is grounded to the chassis.

I have checked the VR PCB components, I have checked Q11, Q112 and Q113 
in the rigth channel part on the VM-7 (O.Mute) line. Nothinh wrong...

I need to find someone to fix the record head alignment on my Dragon 
in Australia.

As far as I understand Russell Storey of Stone’s Sound Studio is on hiatus.
Does anyone have an alternative? 

Kind regards

John Gipps in Brisbane is the best if he is doing any Nak work nowadays.

Also in Brisbane is Bala Ganesh Chandra. Either may take some time.

Subject: [naktalk] Problems with Nakamichi PA-350 Mobile Amplifier - alan505
Message-ID: <004101d3a01c$10124e80$3036eb80$@aol.com>

 

Hi Alan

 

The PA-350 does have some issues. I repaired a few of them in the early nineties, and the majority of problems related to instability in the amplifiers. The four power amplifiers have a tendency to oscillate parasitically. This tends to occur around 300KHz to 400KHz, and can cause the amplifiers to draw very heavy currents from the power supply - whether or not they are outputting audio. Parasitic oscillation can also cause very significant heating in the amplifiers themselves, as it causes cross-conduction in the output transistors.

 

It sounds as though the D-D converter in your PA-350 has run pretty hot at some stage, damaging the resistors that you've mentioned, and quite possibly the semiconductors driving the D-D converter transformer. This may or may not be related to problems with the amplifiers.

 

If I was repairing your PA-350, I would disconnect the four power amplifiers from the power supply, and get the power supply working correctly first. The resistors that you mention, R413 to R420 should all be present - to answer your question, there hasn't been any tech bulletin recommending removal of any of them. Yours have clearly been overheated, damaging the solder joints, and causing some repairer to remove ones that were possibly burnt out. I would remove all the remaining 47Ω 2W resistors and test their values. They are used in pairs soldered in parallel – so they make up four resistors of value 23.5Ω and rated at 4W. They do all need to be present, and all need to be about the same value – you don’t currently have that situation. You could consider replacing each pair with a 22Ω or 24Ω 5W PW5 type resistor (so you could use 4 X 22Ω 5W PW5 resistors, or of course, you could source however many 47Ω 2W resistors as needed to make up eight in good condition – the PW5 types are easy to source.)

 

You need to check Q403, Q404, Q405, Q406, Q407, and Q408. I would do normal junction tests on them, and also Vce breakdown voltage tests. Repairing a PA-350 is not for the faint hearted – you will need a CRO to look at waveforms in the D-D converter – it would be good if you can also test transistor breakdown voltages, so a comprehensive transistor tester would come in handy both for the power supply and the four amplifiers. There are adjustments to be made in the power supply – dead time (VR401) and output voltage under load (VR402, VR403).

 

If you get the power supply working, you could then connect up the four amplifiers and test for any RF on the outputs (the 300KHz parasitic) with a CRO. If one or more are oscillating, I can give you some mods to stop this from happening. Fortunately, most can be made to behave correctly with only a small number of changes.

 

Good luck. Get in touch if you have questions.

                Mobile Amp

I'm setting up a vintage Nakamichi Mobile Audio system in a project car and have been performing some Q/A on my components before I "commit" them to their locations.

 

I have a Mobile Audio Series PA-350 35w x4 amp that I am using to drive 4 tweeters. The amp appears to have a few issues as the only output is a pulsating pop every 5 seconds or so. I pulled the lid off and started checking the state of the grounds when I noticed that two of the resistors on the D/D converter PCB had solder pad cracks, one actually having popped out of the hole.

 

The resistors are the 47Ohm 2w fail-safe resistors on R413 to R420. A closer inspection indicated that R415 & R417 had cracks, but R416 & R418 were actually missing from the board.

 

I'm scratching my head on this one because it appears that something was there from the factory as the pads contain solder, with one end left open.

The PA-350 service manual schematic shows resistors in these locations, so could this be someone's mod or the result of a technical bulletin?

 

I'm curious to see if anyone else has encountered missing resistors at this location. Also, any recommendations of "fail safe" resistors if it turns out that they are needed?

 

Thanks,

Alan

Hi Marcus

I was just poking about in the archives, and noticed an email from David Thompson in answer to your enquiry for a Nak tech in Oz. 

Hi David - thanks for recommending me, and I hope life is treating you well.

I'm not able to take on repair jobs just now - I will be returning to Nak and hi-end audio repairs later this year.

I would definitely recommend Bala if he's doing repairs at the moment.

Regards

John Gipps

I need to find someone to fix the record head alignment on my Dragon in Australia.

As far as I understand Russell Storey of Stone’s Sound Studio is on hiatus.
Does anyone have an alternative? 

Kind regards

There's a place in Louisville, KY, called Magnetic Tape Recorder, Inc. that you could use.  I've had them do repairs, and I have bought equipment from them (a Pioneer RT-909 that I love!).  If you want more information ,write back and I can find a phone number for you.

Call and talk with them, at least, if you're interested in shipping your equipment.

Clean it first with the Deoxit cleaner, then lube it with the Deoxit lube.  My opinion, not a pro...but used enough of the stuff to love it.

Subject: [naktalk] Tape playback sound quality issues on different NAK decks?
Message-ID: <161ab41dd91-c8b-1cb3f@webjas-vae189.srv.aolmail.net>

I have a bunch of old metal cassettes originally recorded on a Nak 480 about 30 years ago. I later upgraded to a NAK Cassette Deck1 in the 90's.  I remember back then the sound quality of 480 recorded tapes played on the Casette Deck1 was not as good. Deep bass in particular was a little distorted and high end was more shrill and less defined than the 480. That was decades ago. I now am retired and looking to digitize my cassette archive. I am looking to replace the Cassette Deck1 (which now has some transport issues)  with another used NAK just for tape playback.  I am reluctant to try a more expensive NAK deck like the 660 fearing the tapes may also not playback as nicely as on the 480.


 Does anyone know of any sound quality playback incompatability issues between tapes made on one NAK deck and played back on another?  I have my eyes on the 660 because it has pitch control and seems to be a better deck than the Cassette Deck1 but hoping it would be compatible with a 480.  Can anyone recommend a specific NAK deck that has great playback sound that I can find used under $500 that would sound as good or better than a 480?

I think your biggest factor is going to be if you can get a serviced 
deck and have it aligned to the tapes that you want to archive.  A BX 
series deck might be a good choice.

This made me happy to read. My first Nak was a battered 480 which i had Bower & Wilkins service.

It revealed wonders on my largely 1st gen Sony luggable recorded tapes from the dawn of tapes. So it was magical on my previous tapes and unbelievable on its own.

I have 'upgraded' to 670, 300, Cassette Deck 1, they all make good recordings but none sound as good even after services as the 480.

Overengineered and handbuilt with poorly aging components .... my friend was pissed when i sold it to him he wanted the newer kit, but he hadnt had my learning curve.

Your right the sound is off on the newer ones...from 300 onwards ...i dont think its all the mechanism, ...I agree with the view that Nak felt the need to get the colder less engaging digital cd sound sorted to compete with cd's.

Its a clearer cleaner but different some ambient tonality from the 670 and the 480.

However. The issue of maintaining them does make the later models a better long term prospect as real Nak servicing requires such an investment of time if not money in Nak servicing kit... then there is using it as intended and then the orange cap mularky is also in the equation. They do need servicing every few years unfortunately for those of us in the sticks.

But whilst other and newer models have lower circuitry noise and better specs than the 480 and i think the 600 series... these had that cassette zing that made people realise Naks were special from way back.

Its funny to know that Nak were following to the letter the specs Phillips said was needed
to play and record on Cassettes. The whole cassette period was snookered by an indifferrent profit motive.

Typically for the average user, the original deck will always have the best playback.
If you still own the 480, a competent tech could restore it, with a few of your tapes to verify the head alignment still matches,
for far less than buying another deck, which in all likelihood will not match the alignment that your old deck had.
The alignment is easily the most important aspect of making your ild tapes sound their best. Typically that is azimuth, but azimuth has zero effect on bass, which is more often head height.
Also, any deck that is not absolutely competently serviced will add more W&F which will also degrade the process.
The exception is a Dragon, of course,(dual direct drive, with auto azimuth correction) but a known good serviced one is more than you would want to spend, and if there is a head height issue,not going to solve that.
Of course, if you are getting out of cassettes all together, you could purchase a serviced Dragon, digitize, then resell it, for a total cost far less than $500.
If your 480 is no longer viable then an LX-3 is a close match.
A 660 is also a good choice, though finding a well
Serviced one is a harder chore.

That would be extremely unusual if a Dragon speed was off that far.  Speed
is crystal referenced and the speeds of the two capstan shafts vary
depending on direction since, in a dual capstan deck, the leading capstan
has to turn just slightly faster than the trailing one.  It's also a
diffused resonance deck so the capstans are not the same diameter and don't
turn and the same speeds.  There are some shorting points on the capstan
motor board but they're for slight adjustment of speed to keep the tape
tight across the heads.  VR 501 and 502 are there to balance the waveform
sent to the motors.  I think Nakamichi says to adjust them for minimum
W/F.  I usually just probe the power amps and adjust for the best sine wave
I can.

Azimuth adjustment on the CD-1 was set perfectly. I fold down the signal to mono and adjust azimuth and eliminate skewing. This was not the source of the sound problem. I knew 25 yrs ago when the deck was new that tapes made on my 480 just didn't sound quite as good. I only upgraded after my 480 died and I wanted that adjustable playback head azimuth adjustment feature. Too bad only a handful of Naks have it. It's a very useful feature especially if you did tape trading like I used to

FYI, I trashed my 480 years ago. 
As I posted on another thread, the CD-1 was calibrated fine, no azimuth issues. The 480 tapes sound OK on the CD-1 but it doesn't match the overall tonal clarity of the 480. I have to believe the output stage design was different on the CD-1 vs the 480 from 10 yrs earlier.
I just went for a used 660 on ebay. I'll let you know how it sounds, Since it was produced around the same as the 480 I'm trusting that output stage design will be similar. Also like having a pitch control. I did a lot of tape trading back in the day and let's just say 1.75 IPS is not exactly the same on all tape decks :)

This made me happy to read. My first Nak was a battered 480 which i had Bower & Wilkins service.It revealed wonders on my largely 1st gen Sony luggable recorded tapes from the dawn of tapes. So it was magical on my previous tapes and unbelievable on its own.I have 'upgraded' to 670, 300, Cassette Deck 1, they all make good recordings but none sound as good even after services as the 480.Overengineered and handbuilt with poorly aging components .... my friend was pissed when i sold it to him he wanted the newer kit, but he hadnt had my learning curve.Your right the sound is off on the newer ones...from 300 onwards ...i dont think its all the mechanism, ...I agree with the view that Nak felt the need to get the colder less engaging digital cd sound sorted to compete with cd's.Its a clearer cleaner but different some ambient tonality from the 670 and the 480.However. The issue of maintaining them does make the later models a better long term prospect as real Nak servicing requires such an investment of time if not money in Nak servicing kit... then there is using it as intended and then the orange cap mularky is also in the equation. They do need servicing every few years unfortunately for those of us in the sticks.But whilst other and newer models have lower circuitry noise and better specs than the 480 and i think the 600 series... these had that cassette zing that made people realise Naks were special from way back.Its funny to know that Nak were following to the letter the specs Phillips said was neededto play and record on Cassettes. The whole cassette period was snookered by an indifferrent profit motive.========---------------------------------------------------------========= Also check out the wiki! http://wiki.naks.com========---------------------------------------------------------========= Naktalk at lists.naks.com mailinglistMaintain your account here: http://lists.naks.com/mailman/listinfo/naktalk========---------------------------------------------------------=========

my dragon has started to make a noise when playing  in both direstions coming from the transport.

I first thought it was from the cassette shell itself but when i put in a mirror cassette to take a look, I noticed the tape guides fluttering (vibrating) causing the noise.

The right one on forward, the left on reverse.


they work fine when plying with no tape inserted.

I have cleaned the guides and rollers with no improvement.


It's weird because i just got it serviced a few weeks ago by B&W with new belts and rollers


any info would be useful

As I noted elsewhere I bit the bullet on a 660. Should have it by next week. The seller claims it plays back with no issues. If it meets expectations, I'll digitize the rare stuff I want to archive and continue using the NAK for main tape playback.  As far as recording on the NAK however, one other thing I didn't like on the CD-1 was that it would automatically clip and distort on deep bass frequencies such as pits and dips on vinyl. I don't remember the 480 having that issue but it was years ago. Does anyone know if other NAKs have this same issue with recording deep bass transients?  If the 660 has issues, I'll be looking for another NAK. I'm a forum newbie, can we make deals to buy and sell used NAK's on this forum?

Message-ID: <06ab5939-d0e9-424d-b338-8535f630cb6c@Perrys-iPhone>

Actually, this is not an uncommon defect with the CD and DR decks ( very occasionally on CR decks) and is usually caused by failing muting transistors. I don’t get a lot of CD&DR decks in for service, but when I serviced my ownCD-1 I noticed some bass distortion as well and it was obvious clipping when viewed on my scope.Removal of the mute transistors eliminated the clipping and when I installed new ones, the sound remained excellent. An easy fix to try.

Subject: [naktalk] CD-1 bass clipping

 

Actually, this is not an uncommon defect with the CD and DR decks ( very occasionally on CR decks) and is usually caused by failing muting transistors. I don’t get a lot of CD & DR decks in for service, but when I serviced my own  CD-1 I noticed some bass distortion as well and it was obvious clipping when viewed on my scope.  Removal of the mute transistors eliminated the clipping and when I installed new ones, the sound remained excellent. An easy fix to try.

Could this be a problem on a ZX-9 also? With the output volume on full I 
get similar distortion.

Perry, I also have a CD-1 and a CD-1.5. Which transistor part number did you use? As of now I do not have any distortion in either deck. Many years ago (90's) my 1.5 went to Nakamichi in Southern California. It got a new playback head and a motor. Can't remember which motor. Since then that deck has superb sound! I can't guess how many hours it has on it since then but I'll guess around 50 or so. That's the only Nak I have that I bought brand new however it was a display model but still was in mint condx. Bob N

Hello Nakkers
I have just popped this Nak in... as far as I know its a first service ... i have owned it 15 years or so but i always hoped to get the MX version...

Anyway a long time ago Fred Marrs sent me some belts for it and other Naks with the hope i would speak about my experience with his newly manufactured highly specified Nak belts.

So Im putting it out there that i have a belt or two from Fred back in the belt wars some 20 years back! here on the forum

Its taken some time for the need to come up.

As the machine only plays a tape for some 5 minutes and isnt good at rewinding now Im hoping belts will do it... my engineer fitting for me isnt a Nak specialist but is time served and experienced so if there are any pointers i can send him do let me know as he may find it helpful

Best wishes from Scotland

On the TD-700s I remove the muting transistors entirely.  I am 
wondering if there is much purpose for them in the home decks and what 
would happen if they where left out ?
 
Cheers,

You may need to clean or replace the idler roller.  This link may help.

It was meant as a text to my wife, but somehow I either fat fingered it, or some iphone error occurred , as it somehow turned in to an insane cut and paste to the last email address I used, which was Naktalk.

For what it is worth, I have a BX-100 that I just got a belt kit from Marr.  The secret on mine, to getting good fast-forward and rewind was to replace the "tire" on the idler that drives the FF and REW mechanisms.  I now have a fine machine and am enjoying it very much!

Marr is NOT CHEAP, but they are worth their price, in my never-to-be-humble opinion.

Reply #2:  I reviewed the information at the link and it is SPOT ON!
Put a piece of tape over the small, plastic retainer before you remove it to lift away the idler.  Be VERY careful; it's fragile, but adequate to do its job.
A dental tool is great for lifting off the old tire.  Clean the wheel, then install new tire.  Clean the brass driver, too!
Reinstall carefully.  You'll be up and running in a half-day if you have medium mechanical skills AND PATIENCE.  If you lack patience, the job gets wayyyy harder.....

Dear colleagues
yes the idler wheel problem it is but the belts have been replaced too

i look forward to its return from the engineer

i also lodged a Denon AV receiver which had been to the Agents and said to be unrepairable

It is full of microchips abd very modern circuitry and he was not optimistic about fixing it.

i knew enough to say some sort of solenoid had stopped responding to power on button and later the remote.

lo and behold RS components did a solenoid which he has rigged in

job done... i dont do 5.1 but like the dvds to go to the Tannoys

I was very pleased at his sucessful bodgery seeing Denon didnt supply that part even to themselves

ho la

nice to be in touch and thank you for the idler tips... confirming the inevitable

cheers from scotland

Well, I don't know about others but my interest in whether the fishermen

Message-ID: <21ED46E3-2D10-41DE-9E0C-2C0BD8107B66@pesco.net>

Hi there,

I’m the very happy new owner of a Nakamichi RX-505 that’s in excellent working condition. It does have one issue that’s slightly annoying: On the CAT Bottom Assembly, one of the two tabs that holds the CAT Window in place snapped off at some point before I acquired the deck. (Fortunately, I have the CAT Window.) The window mostly stays in place clipped by just one tab but it does wiggle and is easily knocked out of place when inserting a cassette. 

Anyone happen to have a spare CAT Bottom Assembly? Or a good suggested fix for the snapped tab to secure the CAT Window? (Was thinking a dot of a non-permanent adhesive.)

Thanks so much!

Subject: [naktalk] CR-7A not powering up correctly following belt
 replacement - Cams Cycling
Message-ID: <DM5PR0401MB3688385F1B3E6B9F458DF1C9E0AA0@DM5PR0401MB3688.namprd04.prod.outlook.com>

Replaced capstan belt.  Must have fouled something up.


Cams consistently cycle round twice at power up, pause about three seconds, then continue cycling with occasional pauses for less than a second.  Is control logic cleverly trying to sync logic and cams up as they should be?


Rewind, Play, FastForward, Pause, and Fader up keypad LEDs are lit once cams pause the first time.  Is that a useful error code?


Before powering deck up, twice carefully positioned cams like those of another working unit at power down, thinking there may be required sync between control logic and cams at power up - no help.


Put old belt on again, going back to what worked last.  No help.


No such problem when main "Logic" PCB swapped into another working unit, so I trust I didn't do something to that card, and problem is something to do with transport assembly or its connecting cables.


Display says "Ready".


Capstans never turn, but I see 12V capstan supply voltages on the motor PCB.


Was very careful with motor PCB when belt replaced and cams repositioned manually, seeing those fine coil supply wires and avoiding ESD, but gotta wonder.


I sparingly oiled capstan shafts.  Just mentioning it, despite not seeing how that would matter at this time.


Hoping someone has some insight on where to go next, including but not limited to looking at supply voltages and signals with DVM and/or oscilloscope.


Thanks for anything you might suggest!

Never saw these symptoms, but here are some random thoughts:
1. I would carefully and thoroughly check control motor and leaf switches wiring. Look    for broken wires.

2. Same for connections to the capstan motor PCB. 

3. I would not suspect the belt. (You clearly have an electrical -- not mechanical -- issue)

4. There is no need to preposition cams. A working unit will reset everything during the 
    first power-up. 

5. Not related to the problem(s), but if you lubricated the capstans, make sure the capstan 
    contact areas are squeaky clean before putting in a cassette. Same for the fly wheels 
    contact surfaces and the belt

Good luck,
-- Ron

I have seen similar issues and It was cause from misconnected cables to the logic board. I would double check your cables that attach to logic board and make sure they are in there proper connectors.

Thanks to everyone who responded to my earlier email.  You confirmed my earlier suspicions and earlier today I finally got a chance to look at that deck again.


Looking much closer, I found that a few leads had indeed broken off of the capstan motor board.  That is very easy to happen when they get flexed as you remove the transport assembly, especially considering they don't solder to a through-hole.


Moral of the story:  It a good very good idea to hold that bundle of wires down against the board while removing and replacing the transport so they don't flex where they've been stripped and connected to the board.


Its all put back to together right and working great now.

Actually, there is a hole on the board that I just put a cable-tie through and wrapped around that bundle.  This deck was missing that when I started, but I have very little doubt about what that hole is for at this point.

GREAT news!  I was not a responder, but I'm a "fixer" so I'm glad you slew
the dragon (no pun intended..I think NAK made a "dragon".)

You are welcome. We’ve seen that, done that. Another tip:if you ever work on that CR-7/5/4 drive again is to put 2 inch wide blue painters tape over the whole exposed motor winding area of the DD. It is just too easy to damage the fine wires and exposed Hall sensors when working on it.

Message-ID: <a741de6e-c1ee-c830-93c9-1854af9b6a5d@gmail.com>

Dear Naktalkers,


I have recently tried to order the following caps to Mouser France but 
was not able to do so as I had to order at least 200 pieces if not 2200!

Here is the list of these caps, all in the UKL series (low leakage 
current with which I replace the LN caps):

1 uF 50 V : 647-UKL1H010MDDANA

0.58 uF 50 V : 647-UKL1HR68KDDANA

0.47 uF 50 V : 647-UKL1HR47KDDANA

0.33 uF 50 V : 647-UKL1HR33KDDANA

0.22 uF 50 V : 647-UKL1HR22KDDANA


Is it also true for you guys in the US ?

If yes, which caps do you use instead tu replace these LN caps in our Naks?


Thanks again for your help

Bernard

Message-ID: <CAGF+H7V1LqX=nzGWKrH-5hksASYT1UezB-5SsS4d7RuBwcxQQQ@mail.gmail.com>

Hey all.

Doing my yearly service of my lx-5 and was getting low output levels.
Couldn't figure out what it was so I replaced the op amps and caps for the
rec/playback/headphone circuits and troubleshot a bit more. Same issue.
Noticed that the fader controls now don't do anything, meaning that both
lights are always on and the fader buttons do nothing. Checked the buttons
themselves and they do work, but I'm guessing the 4556/ic501 is bad somehow
or the fader circuit is stuck?

Any ideas?

Just cleaned out the switches, connectors, and tinned everything up.
Checked all the switches/connectors with the multimeter.
Good news: The fader now goes through the correct startup procedure and
stays in the fade up mode
Bad news: It stays in the fade up mode and pressing the fade down lights up
the fade down, but it snaps back up.

Since it isn't the switches so that narrows it to either a bad trace or a
bad component. I'm not sure exactly how the fader works so any tips would
be appreciated.

Ok I figured it out. Looked at the circuit for the fader and it uses a high
current output op amp (4556) with a 1/2 w zenner. I took out the opamp and
checked it's short circuit current and one side was giving a round 1/3 of
the rated current for the chip. I subbed it in with one from my parts box.
Works fine now. 😂

Checking over some things and I noticed the nak service manual says "adjust
to maximum" for the record bias trap. Shouldn't it be minimum? Playback
trap says adjust to min but I would think that you would want the minimum
for both.
Thoughts?

Hi,

Apparently, I won a broken Dragon where the owner was told it needed a 
lamp and sensor to play.  It does FF and RW.

Is the sensor and lamp easy to replace and are parts available or is 
this one of those ESL phone calls?

Doesn’t sound good. If you can FF and RW without the auto stop kicking in, the auto stop light bulb and sensor should be good.  There might be other issues.

Remove the metal cover of the well door and look carefully at both pinch rollers as you depress “Play” (without a cassette).  Do they both engage and move all the way up, until they get in firm contact with the capstan shafts, play a little bit (until the auto stop figures there is no cassette in the well) than move back down, to the Stop position?  Try playing in both directions.

Chances are the pinch roller arms are frozen with dried grease (and the pinch rollers do not engage fully or at all), though there might be other issues too.  Let us know.

I have a Sony WM-D3 Professional and a National (Panasonic) RQ-J6 that are
both in need of service. Does anyone on this list know of anyone who's got
the chops to work on these?

While I'd prefer local (I'm in the San Francisco Bay Area), I'd be willing
to ship them out to a tech anywhere in the US.

Thanks in advance!

I am pretty good on the D3.  The problem is the main plastic drive gear (wheel) cracks.  There is no source to replace the part. I have fixed maybe 10 or so.  I tear them down pull the drive gear and repair it with epoxy and then reinstall, lubricate, align and demagnetize.  You can still hear a very faint "click" each time the repaired area meshes with the idler if you put your ear to the device, but it is quite inaudible while listening to music.  After repair the speed is accurate and there is no fluctuation at all.  I know nothing about the RQ-J6.  Also I am not a "professional".  Just a guy who has fixed a bunch of them.  I have 5 WM-D3s in my collection.  I feel it is the best sounding small portable cassette player there ever was.  Not nearly as good as the D6, but the D6 is more than twice the size and weight.

Hi Everyone, 

I have an audio product that requires jumpers to set the overall output level. I bought some that have 2.54mm spacing and look like others I have, but they are too small. Does anyone know what the next size up would be and where I could buy a few of them? Thanks.

Was clearing my inbox and found this…..I’m way late to the party, I’m sure, but I have a suggestion:  Next time you get a junkmail request to donate money to save a whale or defeat anthropogenic global warming, before you throw that out, strip out the “congealed badger snot” adhesive from the smiley-face coin or whatever premium you earned carefully, and put a ball of it in the best place to stabilize your CAT Window.  Save some extra from future fools’ mailings for later use when cleaning, etc.

Hi there,

 

I’m the very happy new owner of a Nakamichi RX-505 that’s in excellent working condition. It does have one issue that’s slightly annoying: On the CAT Bottom Assembly, one of the two tabs that holds the CAT Window in place snapped off at some point before I acquired the deck. (Fortunately, I have the CAT Window.) The window mostly stays in place clipped by just one tab but it does wiggle and is easily knocked out of place when inserting a cassette. 

 

Anyone happen to have a spare CAT Bottom Assembly? Or a good suggested fix for the snapped tab to secure the CAT Window? (Was thinking a dot of a non-permanent adhesive.)

 

Thanks so much!

Hi Naktalkers,I have a Nak680zx which play and record,but the 400hz test tone is very weak and kind of dulled. In "Cal/Source" mode the fluorescent indicators barely move 1÷2 marks. This makes aliment of the azimuth  not possible. The recording without azimuth come out good,but a little weak./PH and RH are not in correct  position. /Any thoughts will be very appreciated. Vesselin.

Hi Vesselin,

PB and REC head must be perfectly alligned otherwise the calibration will not work.
Begin by adjusting the PB head with a reference tape and then the REC head. Good luck.

I have a Nak680zx which play and record,but the 400hz test tone is very weak and kind of dulled. 
In "Cal/Source" mode the fluorescent indicators barely move 1÷2 marks. This makes aliment of the azimuth  not possible. 
The recording without azimuth come out good,but a little weak./PH and RH are not in correct  position. /
Any thoughts will be very appreciated. 
Vesselin.

A weak test tone when in Source mode is almost always because the polypro orange cap in the tone circuit is bad.
There is only one, in the section where the tone is generated.
Head alignment has nothing to do with it when in Source.
There is a level adjustment for the tone, but there is not enough adjustment for THAT low of a signal.

Are you selling a CR-7A or a CR-7E. The difference is the voltage. The "A" stands for America with it's 120 volts. The "E" stands for Europe with it's 220 volts.  Although to be technical about it there were two versions of the "E" model -  the regular one at 220 volts for Continental Europe and a special one at 240 volts just for the UK. If not sure, check the back of the unit where it will list the voltage.

Sensor lamps are ok since it will FF and RW.. A cam belt replacement may be
what you need.

Deck 1 needs a new (substitute) reel motor. Some motors will run for days
before going dead.
As for deck #2, stop using C120s.  Nakamichi warned against using these.
The suggestions about back tension may help. Dirty pinch rollers can also
cause tape skewing like you are observing.

Hi everybody,


I've posted this already but I don't think it has gone thru so I'll try again.


I have a 581 I have not used for a while. The last time, about a couple of months ago it played perfectly. Now, however it doesn't produce any sound. The transport is fine, output level is on maximum yet there is no sound. The needles don't move either. I've noticed that the play and stop light bulbs are burnt out but other than that all seems fine except the lack of sound. Any ideas?

Thanks


Peter

Hi Peter,
If the stop bulb is burnt out the circuit doesn’t give signal.
Replace the bulb .
There is however a modification. That modification is to solder a resistor in the circuit.
If you want to go that way, send me a mail. I can give you details.
Best regards
Norman

Yes Bob, I was talking about the bulb from the STOP key that activates 
the muting line.

And you can add a resistor as indicated in the mod to avoid any further 
trouble if the new bulb were to blow again.

Thanks, Bernard. I've checked that WIKI file. I'll try to replace the stop bulb as soon as I can get hold of one. I think I even have a whole spare assembly of those control buttons somewhere.

We are referring to the small lamp in the front panel stop button, not 
the auto-stop lamp.


I ran into the same thing on a 680 a while back, it drove me crazy until 
I figured it out.  I added a 1k resistor across the lamp along with 
replacing the small lamp and the playback audio came back.

Message-ID: <xAvsBvksQtcQn/IQUouN1a@HW9hD1lStlDSMVp2oodm8>

I have a Nakamichi CR-1A with a wonky Transport Control chip, that
works for a few seconds until it warms up, or for longer if cooled
with freeze spray.  The chip is a B11020A, used in several transports,
a 8818H (could refer to firmware), based on a Toshiba TMP4315BP.  Does
anyone have one to sell?

Thanks for the help, all. I soldered in the resistor as per the wiki page and the sound is back. The little bulb seemed almost impossible to change. Broke the two old spares I had and I don't know where to get hold of new ones. There is no stop light but the deck works so thanks again.

Thanks, Bernard. I've checked that WIKI file. I'll try to replace the stop bulb as soon as I can get hold of one. I think I even have a whole spare assembly of those control buttons somewhere.

I might be wrong but I think your problem is the burnt STOP bulb, see attached files (from WIKI)

Hi everybody,

I've posted this already but I don't think it has gone thru so I'll try again.

I have a 581 I have not used for a while. The last time, about a couple of months ago it played perfectly. Now, however it doesn't produce any sound. The transport is fine, output level is on maximum yet there is no sound. The needles don't move either. I've noticed that the play and stop light bulbs are burnt out but other than that all seems fine except the lack of sound. Any ideas?
Thanks

Peter

Good day everyone,
I Just read that Woot from our group here has control chips for the CR1. Would you, root, or anybody have the master chip for the RX202 for sale? I just refurbished the entire deck and all I need to complete the job is this chip.
Thank you for any help you may provide me with!

Hi all, I got my CR-3 out of storage and no surprise it didn't want to work as far as the transport goes. Cleaned and lubed and the transport is now working but has an intermittent problem.
It will play fine for quite a while then go crazy. It will stop playback, pause light will come on, reel motor will stop. After several attempts to FF it will finally go into FF. At this point the only way to get it to go back to play is to attempt to manually turn the control motor gear. This may or may not work.
When the reel motor stops, it's voltage goes to zero also. As long as the reel motor is getting voltage (5V on FF and somewhere around 2 - 3V in play) it runs fine.
I've checked voltages around I think it's IC608 and related circuitry however since it's intermittent I can't find anything wrong.
Is this problem familiar with anyone or does anyone have an idea on how to proceed?
Thank you, Bob N

Hi all, I got my LX-5 out of storage. The transport would not engage however after a clean and lube it works fine but sometimes I have to hit either PAUSE or PLAY a couple times for it to go completely in to the selected function. After a couple times the unit seems to work fine.
Does this LX-5 just need a little more exercise or should I do something else? The control motor belt was replaced about 7 years ago with a Fred Marrs belt. The belt appears to be in good condition and also appears to be a good fit.
Any ideas would sure be appreciated.
Thank you, Bob N

 It appears like the problem is the control motor. I cannot make it move and the windings measure 450 ohms with it electrically removed from the circuit. When a function button is pressed I get 6 volts or so for less than a second then goes back to zero volts.
Any ideas would be appreciated.
Thank you, Bob N

The LX-5 more than likely just needs a new cam belt. 7 years, with any good length of time unused, and they start to slip SBM-4.8 is ideal.

CR-3 sounds like it needs a new cam motor, fairly common failure. The reel motor probably too, as this is a dog chase tail instance. Voltage goes away because motor stops due to dead spot, not usually the other way around. Never (well very rare) seen a transport just intermittently stops sending voltage in a mode. If you can leave it on FF w/o a tape basically indefinitely, then it is not likely the logic. Dead spot only occurs in play mode.

Perry, Thank you. On the CR-3... I've never seen a good motor that has a winding resistance of 450 ohms so I did figure out that motor is bad. I've seen other part numbers for new motors on forums so will try that. Any opinions on a new motor would be appreciated.
The LX-5 had a new control motor/cam motor belt about ten years ago but has very little mileage on it, but it is ten years old now. Easy enough to do on those so will try and get one from Marrs.
Thank you, Bob N

Perry, and all, For the LX-5, After thinking about it for a day I now remember that the idler tyre is always coming in contact with the reel table/spindle but doesn't always get "traction" on the reel table. This tells me the control motor/cam motor and belt are doing their job. 
I tried to clean the tyre, I only had denatured alcohol, no rubber cleaner however I figured I had nothing to lose. I also "roughed" up the tyre rubber. These two steps got it to play 8 times out of 10, and the 2 times it did not play going from stop back to play a couple times got it to go. 
Everytime it had a problem it was the tyre not getting traction on the reel table.
In stop mode it felt like the take up spindle was a little tough to turn however it feels the same as my other LX-5 which works fine.
Any comments?
Thank you Bob N

Hi everyone,

I have a Nakamichi RX-505 that was serviced fairly recently. A while ago, it developed that squeal when engaging the transport and I haven’t had a chance to lubricate the cam drive gear shaft. I don’t use the deck more than a couple hours/week.

But yesterday, after a few weeks of no use, I tried playing a cassette and the UDAR just keeps triggering as if the deck has reached the end of the tape. (Tried multiple tapes and have the same issue.)

Here’s a video:
https://youtu.be/2Z5O1tmLeDY

When I press play with no cassette inserted though, the spindle spins.

Here’s a video:
https://youtu.be/KWbPHzqMVbg

I haven’t opened the deck yet to apply the oil to the cam drive gear shaft. Could a lack of lubrication there cause this? Any other ideas?

I appreciate the help!

Thanks,
David

Hi David,

On the RX-505, This behavior typically happens when the tape is not 
correctly "tensed"  (sorry but not sure with this word), I mean too 
loose, and is not pinched between the two pressure rollers and the two 
capstans, or at least the take-up one. Actually, the tape goes abose the 
capstan instead of going below it, therefore the deck behaves as you do 
have any capstan traction.

Tis is why it does spin when you do not insert a cassette.

To probe this hypothesis, please insert in the deck a tape for which you 
will have tensed manually the tape and check if the behavior changes.

If it does, the problem can come from a poor cam belt.

Let us know

Bernard

  Hi all, I got my CR-3 out of storage and no surprise it didn't want to work as far as the transport goes. Cleaned and lubed and the transport is now working but has an intermittent problem.

  It will play fine for quite a while then go crazy. It will stop playback, pause light will come on, reel motor will stop. After several attempts to FF it will finally go into FF. At this point the only way to get it to go back to play is to attempt to manually turn the control motor gear. This may or may not work.

  When the reel motor stops, it's voltage goes to zero also. As long as the reel motor is getting voltage (5V on FF and somewhere around 2 - 3V in play) it runs fine.

  I've checked voltages around I think it's IC608 and related circuitry however since it's intermittent I can't find anything wrong.

  Is this problem familiar with anyone or does anyone have an idea on how to proceed?

  Thank you, Bob N

Hi,

Thanks for the reply!

I tried with multiple cassettes that I know are good and the problem persisted. 

Is it likely to be anything other than the cam belt and is replacing it an easy fix? 

Lastly, can anyone recommend a good tech in the SF Bay Area? I’d prefer not to deal with shipping it out. I’d love to drive it over to Willy Hermann but as I understand it, he has a very long wait time and, more importantly, only does complete rebuilds these days. 

Thanks!

Did you get that info directly from Willy? If not, contact him directly. He has a website and I believe his phone number is on there, or at least his email address.

You may need to clean the reel drive idler, the small rubber wheel 
between the two spindles.  It looks as though you have no take up torque.

You may not need to replace it, it might just work after a cleaning.

This website can give you some information about what to do.

I see this deck has the Nak "classic" mech, not the Sankyo transport.  
It can be tricky to work on.  The previous email I sent probably does 
not apply.

I would remove the transport, dissassemble it, clean out the old grease 
and oil, relube it, realign it.  This may be beyond what you can do, not 
knowing what your experience level is.  You may be able to clean the 
idler tire, but it is not so easy to get to. The transport is assembled 
like a sandwich, and the roller is inside of it, not easily accessible.

Good luck with it.

Subject: [naktalk] CR-3E won't erase
Message-ID: <mailman.0.1533795536.3354.naktalk@lists.naks.com>

Greetings from Finland.

At first my native language is not English.


Nakamichi CR-3E won't erase the tape. I have googled many times and 
found out that it must have something to do with OSC board (what is 
it?) and orange drop capacitor(s) in it.

Unfortunate I cannot read schematics - but can solder, if somebody 
shows me exact capacitors to change. Does anybody have the photo of 
that model's "Osc board" and what capacitors to change.

Many thanks

Yes, just confirmed from Willy:

"Over the years I have found that doing specific repairs is not advisable given the age of these decks. Such service is essentially me giving the deck a clean bill of health.  When something breaks in six months you think poorly of me.  Consequently, all I do is full service which repairs any specific problems and entails removing the transport mechanism, dismantling it, cleaning out old lubricants and replacing them, replacing needy rubber parts, mechanical calibration, reassembly, electronic calibration and verification of original specifications.  After a rebuild I return the deck to you with a one year warranty - the same as when new.  Cost for a rebuild is around $550.  
Right now my wait time is around 9 months.”

I truly respect his approach and his Nak mastery but unfortunately I can't afford a complete rebuild right now. So I’m just looking to have this new issue repaired in the hopes that the unit will continue to work (for a while anyway) as it did until a few days ago.

Ah, thanks for this. I was excited for a moment about cleaning the reel drive idler as a possible fix... until I saw your second email. I appreciate it but yes, removing the transport, etc. is beyond my ability and I’ll need to find a tech for that. I appreciate your help though!

thanks,

I would have to agree with Willie Herman here.  What I have done is buy
them "broken" on ebay, rebuild them, realign them ( I use a Sound
Technology 1510 and some old but good alignment tapes) and "flip" them back
to ebay.  I don't usually charge as much as Willie, but it always ends up
taking a lot of time, so to be fair, "around $550" is a reasonable price.
On a 40 year old consumer audio piece, particularly an electro-mechanical
piece, there is usually a lot to do to bring it back up to original specs.
I am "likenuagain" (like new again) on ebay, but I have nothing up there
currently.  It's tough to do while working full time as well.


I see this deck has the Nak "classic" mech, not the Sankyo transport.  It
can be tricky to work on.  The previous email I sent probably does not
apply.

I would remove the transport, dissassemble it, clean out the old grease and
oil, relube it, realign it.  This may be beyond what you can do, not
knowing what your experience level is.  You may be able to clean the idler
tire, but it is not so easy to get to.  The transport is assembled like a
sandwich, and the roller is inside of it, not easily accessible.

I haven’t opened the deck yet to apply the oil to the cam drive gear

LX-5 update...
After letting the deck sit for a few days then trying it Perry was right, the cam motor runs fine but doesn't totally drive the gear into position so the motor will still run as it's trying to get it to go all the way into position. After a few tries it does go all the way into position but then the idler tyre cannot get enough traction to spin the reel table/spindle.
This tells me that Perry was right, a cam belt is probably needed (will try more cleaning just to make sure) but does need a tyre. I've never done a tyre on a classic transport so I'll have to find myself a few hours of uninterrupted time (not easy) to get it done.
When it does play/and or record, the sound is fantastic so this deck is worth the time. Another kinda bonus is it's a dual voltage unit, 120V or 240V. Not that it's a great thing, just kinda cool.

The LX-5 more than likely just needs a new cam belt. 7 years, with any good length of time unused, and they start to slip SBM-4.8 is ideal. 

CR-3 sounds like it needs a new cam motor, fairly common failure. The reel motor probably too, as this is a dog chase tail instance. Voltage goes away because motor stops due to dead spot, not usually the other way around. Never (well very rare) seen a transport just intermittently stops sending voltage in a mode. If you can leave it on FF w/o a tape basically indefinitely, then it is not likely the logic. Dead spot only occurs in play mode.

You may need to clean the reel drive idler, the small rubber wheel 
between the two spindles.  It looks as though you have no take up torque.

You may not need to replace it, it might just work after a cleaning.

This website can give you some information about what to do.

Hi. Recently purchased a 482 online. It's the first deck I've brought so by default I'm a rank newbie to the scene. Provided it plays a cassette ok (fingers crossed it does), is there anything I should or could look at doing to it to make sure everything is ship shape. Aesthetically is looks pretty tidy based on the pictures. Play count is at 342. Any tips, ideas or recommendations are appreciated. Thanks in advance.

Hello, Chris.
If the deck was not serviced, you need to service it yourself or order
service in a good company / from qualified person. For example, if it
was not serviced, transport need cleaning and lubrication because old
lube has "dried", and all orange polypropylene caps must be replaced
(not with identical orange caps but with reliable analogs). There may
be many positions you have to pay attention to if you want the deck to
have accaptable reliability and durability. I bought the Dragon some
years ago and had "fun" serviving it... If you want, you may take a
look at my "report":
 https://www.dropbox.com/s/nyzvfllw4t1slkd/Dragon%20Service%20List.pdf?dl=0.
Since the time I made this report the PB head has polished with the
tape so now it performs well, but I had one strange problem with
direct drive (may be related to Hall sensors). So don't expect the
great reliability, these decks are very old, even semiconductor
devices are not reliable at such age.

The chip arrived, I've installed it, and the deck is playing again
(and stays in play!).  Thanks, Perry!

The deck may need some cleaning.  It's been idle for a long while with
the bad chip.

Hi Perry,

You wouldn’t have the big control chip for the RX202 would you? I can buy the chip, but where do I find the program/software that’s supposed to be in it?

Thank you for any help.

Regards,

Rodrigo Krause

Umm, yeah, that is not a play count. Its just a tape counter, meaning its a number that keeps
Track of where you are relatively, on the tape. It does not count the number of plays. 482 has a myriad of potential issues, mainly,broken eject cable mount due to nylon shrinks and metal screw doesn’t. Then there is the typical classic transport issues, idler tire, capstan&counter belts and counter sense bulb. Good luck.

Sorry, no control chips for a 202, except the ones in mine.

That wasn't me, but people are now looking toward you as a Genie!

Hi all, I have a non working CR-3 (120 volt) I'm going to list on e-bay but thought I'd mention it here first.
I believe it has a bad control motor. I started having problems with it but I could "help" the motor go into position and the deck would play. It sounded good. The more it was used the worse it got and now it stopped with the head/pinch roller assembly is now stuck in the play position. The motor is getting voltage when commanded.
I don't have time to work on this. Does anyone want it for 40 US dollars plus shipping?
The cosmetic condition is I would guess an 8 out of 10. Will take pay-pal or money order.
Have a great day.

Does anyone have an educated guess how much it would cost to ship a tape deck from the west coast USA to the east coast USA?
I did the USPS online calculators and ended up with $8 to $38. I would greatly appreciate it if someone that has shipped before can give me an approximate price of what they paid.
Gabriel, I answered your e-mail. Did you get it?

Not sure why. I did send you an e-mail directly from my other e-mail address this morning, "G-mail" Did you get it? the g-mail is the address I use for my pay-pal.
Send me a direct e-mail so then I can contact you.

Greetings all!

 First time ever using this mail service, so bear with me if I actually emailed the wrong address or something!

I have an RX-505 that I nabbed on eBay recently completely unknown of condition internally. I received it in post and all is well surprising(other than needing probably a new capstan belt, and definitely needing a cam belt) she sprang into life! ...well excluding one big thing... the plastic piece that rotates the tape back and forth is missing! (Where the tape physically slides into) Definitely a important part! 

  Question is, does anyone have that piece? If not, is it possible that I can retrofit the “sled” from the RX-202? Obviously it’s much cheaper to find parts units on eBay of 202’s. There is physical differences of the assembly. The 303&505 are larger in appearance; though I’m only going off of pictures, and lastly the hole placements is different. Not a big deal though, as I could just drill a hole in the middle of the assembly, right? Anyone know if the actual assembly that attaches it to the tape deck is the same (the part that slides into the brass stud with c clip and gears)?

Who knows. Hopefully someone here does!! Any help anyone? Would really appreciate it! 

Thank you
Brandon.

Hi, Brandon

Just wanted to say "welcome," and that your message posted well and was perfectly readable.

Now for the bad news:  I don't have a clue about the answers.  But you can bet that if anyone here does, you'll hear from them.
Best forum I've seen for helpful folks.  KUDOs to all.

Hi Brandon
Not aware of where you are located but I have a sled assembly for the RX505 that I bought a few years ago to fix my RX505 before deciding it was too hard.
In Australia if you are interested. My cost plus postage to your location.

Brandon,I'm unclear on which part you want; the cassette sled or the clear plastic window? It makes a difference because the sleds are out there as in Steve K's offer, but the clear cassette window is probably the most unobtainium part of all Nak decks. Finding one pristine would be like digging up a gold doubloon in your backyard.

I have a 505 and love it...very dryly analytical. But for my ears, I always defect to my 700ZXL. You will need a belt kit including idler tire at some point. There is also a part in the drawer that is very easy to break....a gear I think it was that can receive NO force. I waited quite a while to find one. Also, you don't have to split the transport apart to put in the belts and idler tire. You can take a jeweler's screwdriver and heat bend it to a 90 degree to get at the fasteners you need to. Just look at it a long time before you start and you'll see what I mean. 

I had hoped by now that 3D printing would have become more available to the masses, but it's largely been over-hyped. That clear cassette window could be printed rather easily from an original. You won't be able to retrofit the drawer from a 202.  That's a question that has been posted many times before, due to the availability of parts

Hello Naktalkers,


I am looking for a 670ZX level meter (0B08716A).

The deck I have restored has a meter definitely dead and not reparable 
(at least into my hands). Otherwise, it works really fine.

If one of you has a spare one and is willing to sell it, I would jump on it.


All the best

Bernard

I have one from a 660 where one of the two meters is dead - can't remember if they are separate or not.  

If you want it, you can have it.  I am in New Zealand, so postage would be the only cost.

Cheers.
Ken

Hello Naktalkers,


I am looking for a 670ZX level meter (0B08716A).

The deck I have restored has a meter definitely dead and not reparable (at least into my hands). Otherwise, it works really fine.

If one of you has a spare one and is willing to sell it, I would jump on it.


All the best

Bernard

Hi Ken,

Thanks a lot for your help.

I have exactly the same problem (only one is dead) but I am not sure how 
easy it is to remove one and re-insert it in the VU-meter chassis.

Give me some times to check and I will come back to you.

Best wishes

Bernard

I have a Nakamichi 700 which I have owned for about 45 years now.  I've overhauled it a couple times (belts, etc) and still play my old cassettes on it but none of my children see any use for it so I'm going to sell it.  What's it worth?

Thanks for any input.

Hi all, It looks like I gotta replace the idler tire on my LX-5. I've never done one on a classic transport. It looks like the transport has to come out. I have the service manual so I can see the diagram but would like to know if there's any tricks I should know about.
I'm not going to attempt it unless I have at least a half day so I can take my time.
Any hints would be greatly appreciated.
Thank you, Bob N
