So far, I have only looked at the files on CD # 1. Actually, the only track which was clipped is # 2 but almost all of the other tracks have a sound that has undergone intense compression. The only track that's OK is # 5. This track has good dynamics and seems completely unaffected. The result if listening to the whole CD will be that Track # 5 will sound considerably weaker strength-wise than all the other tracks on the disc, for which there are hardly no artistic reasons but only because of improper mastering on this CD. If we take the track # 1 as an example of the hard dynamics compression I have let this track undergo a process that I have developed over many years of working with audio restoration. Please note: I do NOT use a dynamic expansion device for this procedure - I do NOT! This is a data process that searches for square waves in the audio signal, and they occur all the time when audio compression is used. The stronger a transient becomes compressed = the wider becomes the square wave after the compression. I enclose a picture where you see the visual outcome of this process. The left half part of this picture shows visually the dynamic of the "original" Track 1. The right part of the image shows the dynamic of the same track after it has undergone my process. As yo can see, there are lots of transients that were completely removed and flattened to square waves in the left, hard compressed original. You can listen to the results of my restoration process. If you compare those restored files with the unrestored files you will find that the unrestored files are much LOUDER than mine. This can fool many listeners to judge the louder files as better sounding, too. But if you raise the volume knob when listening to my processed files, they will be louder, too. It is a matter of volume adjustments. Aming my restored files is track # 5 missing because it didn't ned any restoration.

While the audio technology offer us more and more dynamic space, the recording industry reduces to lower and lower dynamic ranges. They call it "REMASTERED", an expression that gives the misunderstanding that the newer CD releases has gotten an improved quality, while the truth is that they only have made the dynamics even lower than it was before. This can fool many listeners, sometimes even me (embarrassing!) that it sounds better just because it sounds louder. This is even worse in the radio broadcasting industry, but there seems to be hope for improvements in the EBU (European Broadcasting Union) countries, and perhaps this might spread to other parts of the world.

For some strange reason, my computer no longer agrees to produce ISO files. Rather than spend time debugging, I saved the Marathon project into two RAR archives: 10 tracks for CD1 and 11 tracks for CD2. All tracks are in FLAC format. Download the CD1 archive (File CD1.exe) from https://www.dropbox.com/s/vjmq3lktdoeyrdl/CD1.exe?dl=0 Download the CD2 archive (File CD2.exe) from https://www.dropbox.com/s/8bhiruuzjnh378w/CD2.exe?dl=0 To extract the FLAC tracks: If you have the WinRAR program on your computer, simply double click each archive file. The password for file CD1.exe is MarathonCD1 (case sensitive). The password for file CD2.exe is MarathonCD2. If you do not have the WinRAR program on your computer, download a trial copy (it's free) from http://www.rarlab.com/download.htm and install it. Make sure to download the version (32bit or 64bit) appropriate for your Windows version. Once the FLAC files are extracted, you can listen to them on the computer, or burn to CDs. If you do not have a FLAC codec on your computer, you should firts download and install file flac-1.2.1b.exe from https://sourceforge.net/projects/flac/files/flac-win/flac-1.2.1-win/ The Marathon tracks will be available for download for a week. Please note: these tracks are NOT for sale. Please DO NOT GIVE THE PASSWORDS OR FILES TO ANYONE WHO IS NOT A NAKTALK MEMBER.

For example, common red and green LED's require approximately 2 volts. The less-common white and blue LED's take about 4-5 volts. Current is typically 10mA. An LED will replace a point-source incandescent indicator lamp with no trouble. The only problem is finding where to mount the outboard series dropping resistor, since the original lamp generally uses 4-10 more volts than the LED requires. I have seen literally hundreds of instances where this resistor has been installed in a manner that looks tacky, and presents some hazard to surrounding circuitry -- or where the value of resistor chosen is technically incorrect, resulting in damage to the LED. LED's are a poor choice for the ubiquitous "fuse type" lamps used in the radio dials of vintage stereo and quad receivers. Since they are point sources, and fuse-type lamps generate an emission >.5" long, many "upgrades" from fuse-lamps to LED's result in an unpleasant fence-post effect, in which the light and dark spots alternate across the dial. At my shop, I've had to "undo" a few "upgrades" because the LED's were so ugly.

Since they aren't the OEM version, I'm probably being extra cautious. The hardest part is that the OEM bulbs have legs that are very fine wire and easy to bend/form. The legs are these are much thicker. I plan to push them into the socket as far as possible to give a little bit of working room and then use some very small jeweler's pliers to bend then into position. We'll see how many of them that I break... Fortunately, they are inexpensive so if I break a few it doesn't really matter (53 cents each in singles, 41 cents each in quanitites of 10). Cheryl From: naktalk-bounces at naks.com [mailto:naktalk-bounces at naks.com]On Behalf Of Ron Sent: Tuesday, May 17, 2011 5:02 AM To: Talk about Nakamichi Cassette Decks Subject: RE: [naktalk] UPDATE - Nakamichi 582 bulbs | Cheryl, a better way to prevent overheating is to use lamps rated for the correct voltage and current.

I have one of the green ones poked into the solder holes of the PAUSE light and it seems to work just fine. They fit nicely in the rubber bulb housing on the 581/582.

It almost sounds like to opposite of what happens to the 580 series when the stop bulb burns out and the playback amp is muted during play. Also, is this happening on the 481z that you put the 480 PCB into? Could the PCB's look essentially the same but produce slightly different signalling methods to the mainboard? I would fix the original PCB and see if that solves the problem.

I have seen some weird behavior on 680ZX meters when the meter oscillator is out of adjustment. In the service manual there is a procedure for adjusting the meters. First the meter module is removed to gain access to the test point on IC907. The internal clock is adjusted with VR901 on the meter PCB to 25.6kHz at Pin 10 of IC 907 on the Meter PCB. The meter is reinstalled and then the meter level pots (VR701 and VR801 on Switch PCB) are adjusted for 0db on the meters with a 400Hz input signal of 100mV at TP101 and TP 201 on Main Board. The input signal is dropped 20db to 10mV on TP101 and TP201 and the VR901 on the Meter PCB is adjusted for -20db on the meters. The two adjustments are interacting so you may have to repeat the 0db and -20db adjustments several times to set the dynamic range of the meters. I hope this helps.

One is the Q424 which simply says mute on the diagram and the other two are Q416 and Q417. It says power mute for those. I am not sure how they would affect the playback amp when the transport is off. I have replacement transistors for them but unless I am sure that they are the problem no point in taking them out. Do you think that any of those large blue electrolytic filter caps near the transformer could cause this, by the way? Actually there are probably quite a number of them. In any case the deck plays well except the big thump when it gets powered on and playback that does not get switched off when the transport is off.

Early classic transports didn’t have a back-tension assembly, and it was added to the transport somewhere along the track. Nakamichi made a back-tension kit available to Nak Service Centres, and in Australia, our practice was to fit them to decks that came in for repair if they didn’t have one. Models without B/T assemblies were early 480 series, and early 580 series – so 580, 581, 582 are included here. I encountered one (ever) 680ZX with no B/T assembly. Don’t know how that came about – maybe it was produced on a Friday – or maybe we didn’t get the earliest 680 series in Australia. You could source a B/T kit from a classic transport parts deck and fit it to your 582. It should improve tape travelling. The B/T applied in Play mode is about 10gcm, and there is a Nakamichi Back Tension Gauge to test this. Regards John Gipps 1.

If the Auto Azimuth works, that would be fine. If the Auto Azimuth needs alignment do it with the Service Manual. If still there is no high frequent output ask again. Next would be to compare Fwd with Rev.............. Play back amp. Than check the Play back head itself . ( does it look the same on all tracks ? ) After that I would replace some or all polypropylene orange caps. Keep away from track alignment, that is very tricky. That would be much easier with the 1kHz track alignment tape.

But what you need to do from here is basically the same thing. Keep following the signal back to the source of the signal to determine if the signal disappears BEFORE it ever gets to the transistor. If you can isolate where the signal disappears then you have your faulty component. If it disappears prior to reaching the transistor then the transisitor is probably okay. If it is actually lost at the transistor then it is faulty. Good luck!

So I'm kind of stuck on this now. ________________________________ From: Cheryl Kaupp Sent: Saturday, January 14, 2017 3:58 PM To: 'Peter Tanner' Subject: RE: [naktalk] 481Z no playback mute Since the voltage wasn't correct on the logic circuit that you checked then my guess is that you are in the correct area for the problem. ________________________________ From: Peter Tanner [mailto:pbtanner at hotmail.com] Sent: Saturday, January 14, 2017 1:33 PM To: Cheryl Kaupp; Talk about Nakamichi Cassette Decks Subject: Re: [naktalk] 481Z no playback mute Thanks, Cheryl.

Peter ________________________________ From: Cheryl Kaupp Sent: Saturday, January 14, 2017 12:09 PM To: 'Peter Tanner' Subject: RE: [naktalk] 481Z no playback mute Hey Peter, I still haven't had a chance to download the sevice manual. But what you need to do from here is basically the same thing. Keep following the signal back to the source of the signal to determine if the signal disappears BEFORE it ever gets to the transistor. If you can isolate where the signal disappears then you have your faulty component. If it disappears prior to reaching the transistor then the transisitor is probably okay. If it is actually lost at the transistor then it is faulty. Good luck!

I've connected a DMM as you suggested to point 1 and 5 on the logic PCB. In play the voltage was less than 1. In fast forward or rewind was the same. Even less than 1 Volt. Certainly nowhere near 20 V. I've only connected the MM to the logic board as both points were easy to find. So how would I proceed?

Rather than test every one of these components, whicjh could bge very yime consuming, I would try to isolate the circuit where the fault lies. All you need is MM (multimeter), set to the DC Volts function. Connect the black lead (-) to a good Ground point, such as point #1 of either the Logic or Main PCB. Turn the deck ON and press Play. As the cassette plays, touch the MM red probe to point #5 of either the Main PCB or the Logic PCB. Both points should show very low voltage (less than 1VDC). Now, press FF or REW. Both points should show 20V-24V. If both points do, then the fault is NOT on the logic PCB. If neither point does, then the  fault is on the Logic PCB (which, I guess is the more likely result, but one has to make sure). The above is often referred to as 'trouble shooting'. The result will point to the next step in the process, that will further isolate the fault location.

One is the Q424 which simply says mute on the diagram and the other two are Q416 and Q417. It says power mute for those. I am not sure how they would affect the playback amp when the transport is off. I have replacement transistors for them but unless I am sure that they are the problem no point in taking them out. Do you think that any of those large blue electrolytic filter caps near the transformer could cause this, by the way? Actually there are probably quite a number of them. In any case the deck plays well except the big thump when it gets powered on and playback that does not get switched off when the transport is off.

Not sure about the R453 but I think the Q420 has something to do with the real motor. They are hot to touch in playback but don't seem to have any effect on the sound nor on the mechanics.

Rather than test every one of these components, whicjh could bge very yime consuming, I would try to isolate the circuit where the fault lies. All you need is MM (multimeter), set to the DC Volts function. Connect the black lead (-) to a good Ground point, such as point #1 of either the Logic or Main PCB. Turn the deck ON and press Play. As the cassette plays, touch the MM red probe to point #5 of either the Main PCB or the Logic PCB. Both points should show very low voltage (less than 1VDC). Now, press FF or REW. Both points should show 20V-24V. If both points do, then the fault is NOT on the logic PCB. If neither point does, then the fault is on the Logic PCB (which, I guess is the more likely result, but one has to make sure). The above is often referred to as 'trouble shooting'. The result will point to the next step in the process, that will further isolate the fault location.

One is the Q424 which simply says mute on the diagram and the other two are Q416 and Q417. It says power mute for those. I am not sure how they would affect the playback amp when the transport is off. I have replacement transistors for them but unless I am sure that they are the problem no point in taking them out. Do you think that any of those large blue electrolytic filter caps near the transformer could cause this, by the way? Actually there are probably quite a number of them. In any case the deck plays well except the big thump when it gets powered on and playback that does not get switched off when the transport is off.

Let's do the following: please use the same meter that read 5.4V and 21V previously. On the Main PCB, please measure the voltage on the anode of D804 (red probe) with respect to Ground (black probe).

Use the Main PCB assembly drawing that corresponds to the S/N of your deck. If the above succeeds, please measure voltage on the junction of R819, R822 and R823.

Rather than test every one of these components, whicjh could bge very yime consuming, I would try to isolate the circuit where the fault lies. All you need is MM (multimeter), set to the DC Volts function. Connect the black lead (-) to a good Ground point, such as point #1 of either the Logic or Main PCB. Turn the deck ON and press Play. As the cassette plays, touch the MM red probe to point #5 of either the Main PCB or the Logic PCB. Both points should show very low voltage (less than 1VDC). Now, press FF or REW. Both points should show 20V-24V. If both points do, then the fault is NOT on the logic PCB. If neither point does, then the fault is on the Logic PCB (which, I guess is the more likely result, but one has to make sure). The above is often referred to as 'trouble shooting'.

One is the Q424 which simply says mute on the diagram and the other two are Q416 and Q417. It says power mute for those. I am not sure how they would affect the playback amp when the transport is off. I have replacement transistors for them but unless I am sure that they are the problem no point in taking them out. Do you think that any of those large blue electrolytic filter caps near the transformer could cause this, by the way? Actually there are probably quite a number of them. In any case the deck plays well except the big thump when it gets powered on and playback that does not get switched off when the transport is off.

Peter ________________________________ From: Cheryl Kaupp Sent: Wednesday, January 18, 2017 1:43 PM To: 'Peter Tanner' Subject: RE: [naktalk] 481 Z no playback mute I couldn't remember if you ever mentioned that. Here is why I ask: It seems unlikely to me that components for separate channels would fail at exactly the same time. For example the channel pairs: R719/R819, R722/822, R723/823. The same holds true for pairs of caps and/or transistors. So it seems like it should be a component that affects the whole mute cycle -- not just one channel or the other channel. Some cut signals work by pulling the signal to ground -- in other words grounding it out so that there is no output. Others just intentionally create an open circuit or cut off the juice. That was why I asked the NakTalk folks if anyone actually knows how the mute signal works and where exactly does the mute signal turn off the audio output. I keep thinking that you have an open in a circuit that is supposed to pull the audio output signal to ground or cut off the juice but that it is not happening. It could be a failed component, a bad trace, a bad solder joint. There is what I think is a noise filter early in the mute circuit that ties to ground. But it is a ceramic cap and they rarely fail. But you might want to check it anyway -- C319. It also looks like the mute signal ties into the 5V power supply where it enters the amplifier section. Maybe it is supposed to cut off the 5V power supply to the amp. So I would check the components in that area -- C403, C404, R401, R402, D402. C319 is also shared with this circuity. It also ties into the 26V power supply so I would check the components in that area after you check the 5V supply area. The smart thing would be to cut off the juice before the signal is ever amplified. I really wish one of the real electronic nerds would say something. Since both channels are affected I don't think checking components in each individual channel is going to yield an answer but I may be wrong. I'm trying to help but I'm not really the right person to help you. I'm better at the mechanical stuff but these are the places I would look at first BEFORE looking at individual channels. It just doesn't make sense that the actual muting would take place in the separate channel amps. It is either going to mute both channels or it isn't going to mute anything. Hope this helps.

Peter ________________________________ From: Cheryl Kaupp Sent: Wednesday, January 18, 2017 3:03 PM To: 'Peter Tanner' Subject: RE: [naktalk] 481 Z no playback mute I can follow a circuit in a schematic and check most components, but if you want to know what a transistor is supposed to do to the circuit then I'm NOT the person to ask and wouldn't have a clue as to whether it was working or not unless someone else told me how to check it. It may also be that none of them really know how the mute circuit works or as you say -- they may not care because it isn't a Dragon or a CR7A. I have a 682Zx and it is really, really nice. But I also have my original owner 581 and a 582 that I picked up for peanuts off ebay and I love them too. Willy and I have become good buddies but even he couldn't help me when I lost the right channel output on my 581 when Dolby was on. I ended up "logicing" my way through the circuit from the DolbyIn/Out//MPX switch. I narrowed it down to only one possible component that would make a difference between In/Out/MPX and it turned out to be the bad component. I was pretty stoked. Anyway, I also think that the more obscure problems, like your mute issue and my Dolby In issue, don't happen that often and when they do no one knows what to do because they haven't encountered it and fixed it so there is no history. And even if they are real electronic nerds they have to be willing to go through the schematic if they aren't familiar with that machine. Most of the members with problems just hope someone is familiar with their problems and can offer up an immediate fix. You and I can just keep hacking at it over time if no one else jumps in. Eventually we might find it. I may be wrong but logic tells me your issue won't be in the individual channel amps. The mute circuit has got to do something to shut both of them down simultaneously by some means. If I'm right then it narrows down the areas to look at.

All you need is MM (multimeter), set to the DC Volts function. Connect the black lead (-) to a good Ground point, such as point #1 of either the Logic or Main PCB. Turn the deck ON and press Play. As the cassette plays, touch the MM red probe to point #5 of either the Main PCB or the Logic PCB. Both points should show very low voltage (less than 1VDC). Now, press FF or REW. Both points should show 20V-24V. If both points do, then the fault is NOT on the logic PCB. If neither point does, then the fault is on the Logic PCB (which, I guess is the more likely result, but one has to make sure). The above is often referred to as 'trouble shooting'. The result will point to the next step in the process, that will further isolate the fault location. Good luck, -- Ron ________________________________ From: Peter Tanner via Naktalk > To: Talk about Nakamichi Cassette Decks > Sent: Tuesday, January 10, 2017 3:56 PM Subject: [naktalk] 481 Z no playback mute Hi Cheryl, What I've found out is that there are 3 transistors on the logic board of this deck that might have something to do with mute. One is the Q424 which simply says mute on the diagram and the other two are Q416 and Q417. It says power mute for those. I am not sure how they would affect the playback amp when the transport is off. I have replacement transistors for them but unless I am sure that they are the problem no point in taking them out. Do you think that any of those large blue electrolytic filter caps near the transformer could cause this, by the way? Actually there are probably quite a number of them. In any case the deck plays well except the big thump when it gets powered on and playback that does not get switched off when the transport is off.

I have seen some weird behavior on 680ZX meters when the meter oscillator is out of adjustment. In the service manual there is a procedure for adjusting the meters. First the meter module is removed to gain access to the test point on IC907. The internal clock is adjusted with VR901 on the meter PCB to 25.6kHz at Pin 10 of IC 907 on the Meter PCB. The meter is reinstalled and then the meter level pots (VR701 and VR801 on Switch PCB) are adjusted for 0db on the meters with a 400Hz input signal of 100mV at TP101 and TP 201 on Main Board. The input signal is dropped 20db to 10mV on TP101 and TP201 and the VR901 on the Meter PCB is adjusted for -20db on the meters. The two adjustments are interacting so you may have to repeat the 0db and -20db adjustments several times to set the dynamic range of the meters. I hope this helps. It was over 16-years ago when I worked in a Nakamichi Dealer Service department and the memories are fading! Doug Guth HiFi Hospital Hi everybody I have a 680ZX with a display bar for which, after having changed the 3 PP caps of the can, everything is OK but the right cursor ! Now I realize that another deck on ebay has the "reverse" symptom: everything works except the full line of the left channel, while the cursor does work. Is this possible to attribute the function of either the full line or the cursor to a particular chip of the can ?

It may also be that none of them really know how the mute circuit works or as you say -- they may not care because it isn't a Dragon or a CR7A. I have a 682Zx and it is really, really nice. But I also have my original owner 581 and a 582 that I picked up for peanuts off ebay and I love them too. Willy and I have become good buddies but even he couldn't help me when I lost the right channel output on my 581 when Dolby was on. I ended up "logicing" my way through the circuit from the DolbyIn/Out//MPX switch. I narrowed it down to only one possible component that would make a difference between In/Out/MPX and it turned out to be the bad component. I was pretty stoked. Anyway, I also think that the more obscure problems, like your mute issue and my Dolby In issue, don't happen that often and when they do no one knows what to do because they haven't encountered it and fixed it so there is no history. And even if they are real electronic nerds they have to be willing to go through the schematic if they aren't familiar with that machine. Most of the members with problems just hope someone is familiar with their problems and can offer up an immediate fix. You and I can just keep hacking at it over time if no one else jumps in. Eventually we might find it. I may be wrong but logic tells me your issue won't be in the individual channel amps. The mute circuit has got to do something to shut both of them down simultaneously by some means. If I'm right then it narrows down the areas to look at.

It will take me a few days to check all that. Apart from Ron, nobody seems to want to help with this. I am no electronic wizard either. Can change or test a few things here and there but that's about it. Looks like I might have to live this problem. The deck plays well otherwise but I thought the problem might lead to other stuff.

Peter ________________________________ From: Cheryl Kaupp Sent: Wednesday, January 18, 2017 1:43 PM To: 'Peter Tanner' Subject: RE: [naktalk] 481 Z no playback mute I couldn't remember if you ever mentioned that. Here is why I ask: It seems unlikely to me that components for separate channels would fail at exactly the same time. For example the channel pairs: R719/R819, R722/822, R723/823. The same holds true for pairs of caps and/or transistors. So it seems like it should be a component that affects the whole mute cycle -- not just one channel or the other channel. Some cut signals work by pulling the signal to ground -- in other words grounding it out so that there is no output. Others just intentionally create an open circuit or cut off the juice. That was why I asked the NakTalk folks if anyone actually knows how the mute signal works and where exactly does the mute signal turn off the audio output. I keep thinking that you have an open in a circuit that is supposed to pull the audio output signal to ground or cut off the juice but that it is not happening. It could be a failed component, a bad trace, a bad solder joint. There is what I think is a noise filter early in the mute circuit that ties to ground. But it is a ceramic cap and they rarely fail. But you might want to check it anyway -- C319. It also looks like the mute signal ties into the 5V power supply where it enters the amplifier section. Maybe it is supposed to cut off the 5V power supply to the amp. So I would check the components in that area -- C403, C404, R401, R402, D402. C319 is also shared with this circuity. It also ties into the 26V power supply so I would check the components in that area after you check the 5V supply area. The smart thing would be to cut off the juice before the signal is ever amplified. I really wish one of the real electronic nerds would say something. Since both channels are affected I don't think checking components in each individual channel is going to yield an answer but I may be wrong. I'm trying to help but I'm not really the right person to help you. I'm better at the mechanical stuff but these are the places I would look at first BEFORE looking at individual channels. It just doesn't make sense that the actual muting would take place in the separate channel amps. It is either going to mute both channels or it isn't going to mute anything. Hope this helps. Good luck!

D804 play 5.4 volts. FF or RW 1.3 volts. Same on the D704. R819, 719 play 5.4 volts. FF 1.3 R822, 722 play 1.4 volts. FF and rewind less than 1 volt. R823, 723 play less than 1 volt. FF and rewind the same. These were taken with both meters. The older one set to DC manually. They came up with identical results. Not sure if this helps. Peter ________________________________ From: Naktalk on behalf of Ron via Naktalk Sent: Sunday, January 15, 2017 8:36 AM To: Naktalk at lists.naks.com Subject: Re: [naktalk] 481 Z no playback mute Peter, If both meters are good, they should return identical (or almost) readings from the same point, so I am still confused :-). Let's do the following: please use the same meter that read 5.4V and 21V previously. On the Main PCB, please measure the voltage on the anode of D804 (red probe) with respect to Ground (black probe). This should give the same results (5.4V and 21V on PLAY and FF or REW) as the Logic PCB measurements. Please repeat on the anode of D704. Use the Main PCB assembly drawing that corresponds to the S/N of your deck. If the above succeeds, please measure voltage on the junction of R819, R822 and R823. Note that the correct voltage should be low (less than 1V), so choose an appropriate voltage scale. Repeat on the junction of R719, R722 and R723 (should result in the same readings). Do let us know the results. Good luck, -- Ron ________________________________ From: Peter Tanner To: Ron Sent: Thursday, January 12, 2017 5:41 PM Subject: Re: [naktalk] 481 Z no playback mute Hi Ron, I've checked both meters. They are good. The second I got because it has a more accurate frequency counter or read out rather than the older model plus it automatically senses AC/DC. It is a new model and quite an expensive one. The connection was to the ground and to point 5 on the logic board as you suggested. 5.4 volts in play then 21 volts fast forward or stop as before. Other than the mute problem the only other anomaly with this deck is a resistor and a transistor on the logic board that are very hot. R453 and Q420 respectively. Not sure about the R453 but I think the Q420 has something to do with the real motor. They are hot to touch in playback but don't seem to have any effect on the sound nor on the mechanics. Peter ________________________________ From: Ron Sent: Thursday, January 12, 2017 11:29 AM To: Peter Tanner Subject: Re: [naktalk] 481 Z no playback mute Peter, Your measurement results are confusing... The first would indicate that the fault lies in the Logic PCB, while the later result indicates almost (though not quite) normal operation of the Logic PCB. Before doing anything else, would you check both MMs by measuring a standard 9V battery? Also, I wonder if you had the black (Ground) lead of the MM properly connected to actual ground. You may wish to repeat the tests. Or, do you have access to a 3rd MM? -- Ron ________________________________ From: Peter Tanner > To: Ron > Sent: Thursday, January 12, 2017 7:31 AM Subject: Re: [naktalk] 481 Z no playback mute Hello Ron again, I've connected another newer MM to those points on the logic board in DC mode and now I have 5.4 volts in play and 21 Volts in stop or fast forward/rewind mode. Maybe my other meter was in the AC mode, I'm not sure but on this, these are the results.

Rather than test every one of these components, whicjh could bge very yime consuming, I would try to isolate the circuit where the fault lies. All you need is MM (multimeter), set to the DC Volts function. Connect the black lead (-) to a good Ground point, such as point #1 of either the Logic or Main PCB. Turn the deck ON and press Play. As the cassette plays, touch the MM red probe to point #5 of either the Main PCB or the Logic PCB. Both points should show very low voltage (less than 1VDC). Now, press FF or REW. Both points should show 20V-24V. If both points do, then the fault is NOT on the logic PCB. If neither point does, then the fault is on the Logic PCB (which, I guess is the more likely result, but one has to make sure). The above is often referred to as 'trouble shooting'. The result will point to the next step in the process, that will further isolate the fault location.

One is the Q424 which simply says mute on the diagram and the other two are Q416 and Q417. It says power mute for those. I am not sure how they would affect the playback amp when the transport is off. I have replacement transistors for them but unless I am sure that they are the problem no point in taking them out. Do you think that any of those large blue electrolytic filter caps near the transformer could cause this, by the way? Actually there are probably quite a number of them. In any case the deck plays well except the big thump when it gets powered on and playback that does not get switched off when the transport is off.

These are components which doesn't age, they most likely are in the same qualities as when the tape deck was new. Condensors are more probable of errors, not least for building up internal shortcuts within the component. The very most likely cause would be found in some kind of mechanical error, or perhaps connector error. I have thought about the camweel and the possibility that this weel doesn't reach fully to the state where muting is activated. Or if there could be some of the connectors which doesnt transfer this muting voltage because of disconnection in the connector (oxide). I would disconnect all the circuit board connectors and with a thin-oiled brush, rub them a little, and then plug in the circuit board connectors again. But you should never use spray oil inside a tape recorder!

I cannot touch it very constantly, but the sound of the muffled tape seems to change, but just a little bit. This is why I asked you about back tension belt. The capstan belt is fresh, but only 4 mm (width) - while the original one is, i think, 5 or 6 mm. Doing some wow & flutter tests, it gives me 0.9... 0.14% (quite much, not on specs, I know).

Have you checked to ensure that the cam is actually in the right position for each function? Even if it is a little bit off it can cause a problem. I recently ran into this where the unit would go into record mode when play was pressed. I was swapping out a transport and mechanically the cam was assembled perfectly but electronically it wasn't aligning correctly. In my case the alignment was far enough off that the Bowden cable wasn't being triggered correctly. To see if it is aligning correctly you must remove the backing plate so that you can see the cam from the front of the unit. There is a little pointer that points to the positions on the cam. The positions are marked but can be hard to read so you may need to twist your head like a pretzel or figure out a way to mark the cam so that you can read it.

I recently got around to putting them back to work and discovered that quite a few of the class transport naks are having cam belt issues. The models that have this issue so far are Dragon, ZX-9, RX-505, LX-5. About half of the classic transport decks that I tried so far have this issue. I have tried finding just the cam belt on the web but it seems like everyone is selling "Belt Kits" now. Does anyone know where I can order just the cam belt for class transport. Up until about 2010, it was relatively easy and inexpensive (about $5) to order the cam belt instead of having to pay >$40 for a kit. Marrs, ESL and some other ebay vendors are not advertising individual belts anymore. Any help will be appreciated. On another note, most of the sankyo transport decks have idler issues and I found out that ($0.01 plus $3.99 shipping) sankyo idlers are not available on the web anymore!

I used to use CM100s and CM300s myself, and always found it inconvenient that the CM300 required a hard to get 9V battery, whereas the CM100 used a cheap and easily available 1.5V battery. > > I had a look at the circuitry inside both microphones, and tried a simple modification on the CM300 so that it could be powered by a 1.5V battery. It worked very well indeed, so all my CM300 microphones were modified to use 1.5V batteries. If you are interested in this as an alternative to sourcing the 9V batteries, then I will search through old notes and find the details. From memory, I'm pretty sure that the changes were minimal, and only involved changing the value of one resistor - or possibly two - it was a long time ago. From memory, the CM300 was released first, and the CM100 followed. I think Nakamichi may have received feedback from end users that caused them to change to a 1.5V supply for the CM100. Certainly, the tiny output voltages of these microphones does not require the use of a 9V supply, and from memory, most of the available power supply voltage in the CM300 was thrown away over resistors in series with the amplifier. > > Regards > > John Gipps > > > > 1.

I'd love to hear from anyone who has any ideas. Deck 1. Playback shuts down 10-35 minutes into a side. It appears that the idler stops takeup, and the deck then stops before more than a loop the diameter of a pinky finger is pulled out of the shell at the right (takeup) capstan and roller. I changed idler tire to brand new one that I've had good experience with. No change. Deck 2. Began to struggle with thin tape, e.g. 120 minute tapes (frustrating that anyone even used those) a few weeks ago, but now munching some 90 minute tapes. Shorter tapes, on what I presume to be thicker tape stock, seem to be no problem. But when things go bad, the tape is being twisted as it passes the left (supply) capstan, and eventually folded over on itself lengthwise. Any help out there? Thanks for pondering. -Karl P.S. 1. Intermittent motor failure? Heat related? 2. Wondering if the roller(s) have lost suppleness and/or diameter. And one of what look to be guides on both sides of the record head looks worn or damaged.

According to the service manual, it should be about 50 g-cm. If you don’t have a torque gauge, try to stop the take up reel hub with your fingers in play mode and see how it feels in comparison with the one on Deck #2. Does it feel much weaker? If so, you can try adjusting VR601 until you feel the torque is similar on both decks. Make sure you mark down the original position of VR601 so you can go back to the original setting if the issue persists and you don’t have a torque gauge. Yes, you might have a defective reel motor. For deck #2, I would check the back torque (it should be about 8 g-cm). Check the back tension belt - is it loose or gone? Swap it with the one from Deck #1 and see if the problem goes away. I’m assuming you've already cleaned thoroughly the tape paths, capstans and all rubber parts (including the new idler tire). You might want to clean and oil the capstan bearings as well. Not sure about what looks damaged on the left side of the record head. The left (supply) tape guide is on the left pinch roller arm. It is critical. Can you show us a picture? Let us know how it goes. Cheers, Axe Sent from my iPhone > On Oct 30, 2017, at 2:36 PM, Karl E. Fitzke via Naktalk wrote: > > Hi, everyone. When it rains it pours.

Fitzke ; Talk about Nakamichi Cassette Decks Sent: Monday, October 30, 2017 1:59 PM Subject: Re: [naktalk] Two problematic CR-7A decks Hi Karl, For Deck #1 I would check the take-up torque. According to the service manual, it should be about 50 g-cm. If you don’t have a torque gauge, try to stop the take up reel hub with your fingers in play mode and see how it feels in comparison with the one on Deck #2. Does it feel much weaker? If so, you can try adjusting VR601 until you feel the torque is similar on both decks. Make sure you mark down the original position of VR601 so you can go back to the original setting if the issue persists and you don’t have a torque gauge. Yes, you might have a defective reel motor.  For deck #2, I would check the back torque (it should be about 8 g-cm). Check the back tension belt - is it loose or gone? Swap it with the one from Deck #1 and see if the problem goes away. I’m assuming you've already cleaned thoroughly the tape paths, capstans and all rubber parts (including the new idler tire). You might want to clean and oil the capstan bearings as well. Not sure about what looks damaged on the left side of the record head. The left (supply) tape guide is on the left pinch roller arm. It is critical. Can you show us a picture? Let us know how it goes. Cheers,Axe Sent from my iPhone On Oct 30, 2017, at 2:36 PM, Karl E.

This is my first time here... 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, so I haven't tried it. What do I do?

Hi all, I have a CR-5 that has a problem with REW and FF. It seems to work if the take up side is low on tape, other wise it just tries to move the tape then will stop. Tried several different tapes with all the same results. I can hear the reel motor run during this time with no tape movement then as it should, goes into stop. I do not have a torque gauge but measure the voltage at the reel motor on either FF or REW at 6.1 volts, and at playback, 2.1 volts. I'm thinking that since I hear the reel motor running while the tape is stopped, that the idler tyre must be slipping. Going through the service manual there's no adjustment for FF/REW voltage. Any ideas would be greatly appreciated. Thank you.

The MPX button is a mechanical switch with an outer (off) and inner (on) position. For best possible sound the button should always be in it's outer (off) position, unless recording from a very old FM-tuner that has no MPX filter. This filter is for removing the interference that can occur between the FM stereo system's "pilot tone" and the tape recorder's own bias frequency. If there is no MPX filter it can produce "whistle" interferences when recording programs from an FM radio. The MPX button setting has no relation with the battery.

I've done this countless times but was always curious about something with the Tape/Source setting when doing the calibration. I leave it in the Tape position and set Bias and Level. However, in the Source position, the reference Bias level is one bar below Cal and the reference Level is two bars above. Why?

It played well after that with the mute circuit functioning properly. The no mute problem is a fairly recent phenomenon. I'll check the cam again but I don't think it's out of alignment. Most connectors are soldered in with the exception of the heads and the main switch on the logic board. And the playback/record switch which functions correctly. I have not noticed any anomaly and they are all clean. I was wondering if any of the large electrolytic filter caps can cause this kind of problem. In any case I wouldn't know which ones if one or some of them do.

Have you checked to ensure that the cam is actually in the right position for each function? Even if it is a little bit off it can cause a problem. I recently ran into this where the unit would go into record mode when play was pressed. I was swapping out a transport and mechanically the cam was assembled perfectly but electronically it wasn't aligning correctly. In my case the alignment was far enough off that the Bowden cable wasn't being triggered correctly. To see if it is aligning correctly you must remove the backing plate so that you can see the cam from the front of the unit. There is a little pointer that points to the positions on the cam. The positions are marked but can be hard to read so you may need to twist your head like a pretzel or figure out a way to mark the cam so that you can read it. Anyway, when you press play the pointer should point to P and so on for all the other transport functions. There are variable resistors that you can adjust to get the alignment spot on. It could be that if the positioning is off that it is not triggering the mute function correctly. It usually requires that you have to go back and forth tweaking each of the resistors a few times since changing one can affect the others. Willy kindly gave me the info on what ones to adjust on my 581 but I do believe this info is in the service manual -- look for the section on electronically adjusting the cam positioning.

These are components which doesn't age, they most likely are in the same qualities as when the tape deck was new. Condensors are more probable of errors, not least for building up internal shortcuts within the component. The very most likely cause would be found in some kind of mechanical error, or perhaps connector error. I have thought about the camweel and the possibility that this weel doesn't reach fully to the state where muting is activated. Or if there could be some of the connectors which doesnt transfer this muting voltage because of disconnection in the connector (oxide). I would disconnect all the circuit board connectors and with a thin-oiled brush, rub them a little, and then plug in the circuit board connectors again. But you should never use spray oil inside a tape recorder!

But it wasn't a mechanical fault either.There was a bad circuit. Scott told me that the power for the display and mute transistors enters the main PCB thru L 5. We started measuring from there. Everything was okay with the display resistors R719, 819 and the transistors Q804, 704. Then it goes to R 719. That was good too, 21 and 5 volts in stop and play. Then a long jumper all the way to C319, a ceramic cap, one side is grounded. After that there is another jumper then R802 and the mute transistors. When I measured C319 there was no power on it on either side. Since the voltage 21 and 5 volt, stop and play, was correct on the jumper before, Scott suggested to connect that jumper with a wire to C319 making sure that the wire is not connected to the ground side of the cap. And that did the job. Power came back to C319 and to the other jumper after it and to R802 and the mute transistors. It's a long wire, by the way, about 4 inches. There must have been a crack in the board or the wire got broken inside the board between the jumper and C319 some place along. And that's about it. Hope this will suffice for a description. I'm no technician and know very little about electronics so this as best as I can describe this.

I tried:WD40De-Oxit D5Flux - OffAlcoholA non - residue contact cleaner made of mostly Isohexane.

When I did engineering, I'd use CRC but it was only for edgecard, selector or Augat IC sockets that had been left hanging around. Pots were rarely an issue because in design, the projects had a short build life. I do have Caigs for slides and pots, I did order the S721H for the guide paths and heads and CRC QD for cable headers and pins.

I do recommend CRC 2-26 as a contact cleaner - it's a very good one. I would use it for instance to clean a rotary potentiometer (pot), or the R/P switch in a two head cassette deck (a 480, or a 500, 600 etc). I wouldn't use it on slider pots - they need a contact cleaner that includes a light lubricant. In servicing a cassette deck, various different fluids are useful for various different jobs. Solvents like ethanol are great for head cleaning - oils and light greases are useful to lubricate motor bearings, capstan bearings, eject mechanisms, classic transport cams, auto azimuth assemblies etc. Each part needs the right choice of lubricant. Contact cleaners are useful for cleaning contacts, but not for anything else. I’m not sure what Ingemar is driving at when he says (Message: 7 Sun, 12 Feb 2017)… “To completely destroy a Nakamichi, buy a "contact cleaner" spray CRC-2 from Sweden costing an equal of 15 Euro at Distrelec:”. Ingemar, if you use CRC 2-26 to clean contacts, you’ll end up with clean contacts. If you try to use it for anything else, then don’t expect it to be very effective. The link in Ingemar’s email (https://goo.gl/vwmWPU) shows a can of CRC 2-26. You’ll notice that it is supplied with a thin tube. This tube is used to deliver the contact cleaner to the contacts that you are cleaning – eg to inside a rotary pot or R/P switch. It’s there so that you don’t get contact cleaner on parts that don’t like contact cleaner. Various members in the group have their preferred contact cleaners – it just comes down to what is popular, respected, and available in your part of the world. For me, CRC 2-26 has been doing a great job for many decades – but only as a contact cleaner.

S-721H is NOT a contact cleaner. It is only meant for cleaning everything in the tape path - recording and erase heads, rubber rollers, capstans, guides, etc. Many people use alcohol to clean the rubber rollers, but alcohol will dry out rubber.

I would use it for instance to clean a rotary potentiometer (pot),  or the R/P switch in a two head cassette deck (a 480, or a 500, 600 etc). I wouldn't use it on slider pots - they need a contact cleaner that includes a light lubricant.  In servicing a cassette deck, various different fluids are useful for various different jobs. Solvents like ethanol are great for head cleaning - oils and light greases are useful to lubricate motor bearings, capstan bearings, eject mechanisms, classic transport cams, auto azimuth assemblies etc.  Each part needs the right choice of lubricant. Contact cleaners are useful for cleaning contacts, but not for anything else.  I’m not sure what Ingemar is driving at when he says (Message: 7   Sun, 12 Feb 2017)… “To completely destroy a Nakamichi, buy a "contact cleaner" spray CRC-2 from Sweden costing an equal of 15 Euro at Distrelec:”.  Ingemar, if you use CRC 2-26 to clean contacts, you’ll end up with clean contacts. If you try to use it for anything else, then don’t expect it to be very effective. The link in Ingemar’s email (https://goo.gl/vwmWPU) shows a can of CRC 2-26. You’ll notice that it is supplied with a thin tube. This tube is used to deliver the contact cleaner to the contacts that you are cleaning – eg to inside a rotary pot or R/P switch. It’s there so that you don’t get contact cleaner on parts that don’t like contact cleaner.  Various members in the group have their preferred contact cleaners – it just comes down to what is popular, respected, and available in your part of the world.

First, thank you for selecting CD1/Track1, because this was my own contribution to the Marathon Tape Project. If was made from an LP, that itself had been digitally mastered. Publisher of that LP was Orinda Records --  a company devoted to the best possible, 'perfect' sonic quality. Orinda's 'Digital Master Discs' were manufactured meticulously and accompanied by a long, very impressive list of specifications (including 90db dynamic range). While not specifically mentioned, I doubt very much they employed compression in any shape or form. I recorded the LP from a Dual CS-5000 (Shure V15-VxMR cartridge) onto a Nak CR-7a. Before actually recording, I played the track through, making absolutely certain that the highest peaks did not exceed +3db on the deck display (I knew that my specific CR-7a had very soft tape saturation, which was not audible at +3db). The tape was then digitized, with the result distributed on the CD that I used to generate the FLAC files. I played both my file and your processed file for A to B comparison through my computer. (Admittedly, this is not as good as my main system, but still, excellent computer audio.) Aurally, I found very little difference between the two files. Your file level is very slightly lower (I'd guess, 2, maybe 3bd). Attacks are a tad softer (barely audibly) but overall, not quite as 'punchy'. The differences are small. I doubt I would be consistently able to tell the two files apart without immediate A-B comparison. I also notice your file is slightly a bit than the original. Now, here's the funny part... Personally, I prefer the original file to your 'improved' one. The faster attacks just sound livelier. But, just not enough to write home about.

So far, I have only looked at the files on CD # 1. Actually, the only track which was clipped is # 2 but almost all of the other tracks have a sound that has undergone intense compression. The only track that's OK is # 5. This track has good dynamics and seems completely unaffected. The result if listening to the whole CD will be that Track # 5 will sound considerably weaker strength-wise than all the other tracks on the disc, for which there are hardly no artistic reasons but only because of improper mastering on this CD. If we take the track # 1 as an example of the hard dynamics compression I have let this track undergo a process that I have developed over many years of working with audio restoration. Please note: I do NOT use a dynamic expansion device for this procedure - I do NOT! This is a data process that searches for square waves in the audio signal, and they occur all the time when audio compression is used. The stronger a transient becomes compressed = the wider becomes the square wave after the compression. I enclose a picture where you see the visual outcome of this process. The left half part of this picture shows visually the dynamic of the "original" Track 1. The right part of the image shows the dynamic of the same track after it has undergone my process. As yo can see, there are lots of transients that were completely removed and flattened to square waves in the left, hard compressed original. You can listen to the results of my restoration process. If you compare those restored files with the unrestored files you will find that the unrestored files are much LOUDER than mine. This can fool many listeners to judge the louder files as better sounding, too. But if you raise the volume knob when listening to my processed files, they will be louder, too. It is a matter of volume adjustments. Aming my restored files is track # 5 missing because it didn't ned any restoration. Here is the link to my version of CD 1: https://www.dropbox.com/sh/sqummla28c1c8am/AAD3n2CCMCmpiU6qBg4qd1Rfa?dl=0 Ingemar Lindqvist, Sweden 2017-01-02 23:48 GMT+01:00 Ingemar Lindqvist : It might be that those digital transfers are done using high quality equipment, but that doesn't help much if they are recorded with levels above the digital clipping level of 0 dB FS. I haven't tried all the tracks. I only tried the first three tracks, but lost my faith on those transfers when I heard the clippings.  Ingemar in Sweden -------- Originalmeddelande --------Från: LENA WONG Datum: 2017-01-02 23:28 (GMT+01:00) Till: Ingemar Lindqvist , Talk about Nakamichi Cassette Decks , Ron Rubrik: Re: [naktalk] The NakTalk Marathon Tape Project 100% Agreed. - Mike ------------------------------ -------------- On Mon, 1/2/17, Ron via Naktalk wrote: Subject: Re: [naktalk] The NakTalk Marathon Tape Project To: "Ingemar Lindqvist" , "Talk about Nakamichi Cassette Decks" Date: Monday, January 2, 2017, 4:04 PM Do recall that these 21 tracks were recorded by 21 different people, on 21 different Nak cassette decks. It's possible that some oversaturated their analog tape (for my own part, I carefully searched for the optimal recording level over the whole track, but not everyone has the patience). The cassettes were then digitized by a knowledgeable person, on quality equipment, but since not all tracks were at the exact same level, that's another point where clipping could have occurred. Taking all that into account, it's a wonder the majority of the tracks are that clean. There are just a few over-recorded spots. This was a fun team project, where twocassettes traveled all over the world, with each team member along the way, adding his own track, at home, using his home equipment.

One example of this can be seen on the enclosed image. Often recordings like those makes people complain generally about digital recordings. They say that digital audio sounds so HARD and METALLIC".

I'll post a new file on DropBox -- just for this track -- in the near future. To be sure my own file is not corrupt, I will run a compare between the original CD and the backup I made of it immediately after I received it. Please be patient, though.

But if I remember correctly, it was not track #1 which had the worst clippings. Was it not track #3? But I might remember it wrong. The altered version of track# 1, which I achieved, had about 2 dB lower volume (average) than the "original file" because I had with my method recovered the transients, which in the "original" file was clipped. I was therefore forced to reduce the file's overall level so that the highest peaks would have enough "space" level-wise, to not be as clipped as they were in the original file. In order to make an "objective" comparison - if that would be possible - the audio files must therefore be accurately adapted strength-wise. That means in this case that the "original" file must be lowered by about 2 dB. It is surprising how strongly, even the most advanced among the sound tech savvy people, are affected by the factor called psychoacoustics, where most of us, at a listening survey, in most cases will favourize the sound samples that sound loudest and choose them as the BEST sounding. In this case, most people in a listening survey would prefer the file where the peaks are clipped, only because it sounds louder than the undistorted version - if the files are not accurately adapted to each other's loudness.

But on the Dragon it is better not to de- assemble the transport! It is better to bring the transport in the upright position, using a needle or a thin metal, or wooden part to bring one small trop of oil exactly to this cam gear drive , Right in the middle of it. Where the plastic wheel is rotating on the metal part. Both sides if possible. It helps if you turn this cam gear by hand while doing this. The oil will find his place. Better the transport is upright. Normal no need to de assemble the hole lot. regards Gerhard Am 17.02.2017 um 15:36 schrieb Roland via Naktalk: > I just bought my second Dragon in pristine condition with original > box.

The braking force is usually only 1-2 grams while the take-up torque usually is 40 gram. The "number one" most Common Cause Is that the take-up torque is too strong. To measure these torques, service workshops used special kind of weighting cassettes where the torque values could be read while the cassette deck was in the playback mode. Adjustments were made by adjusting the slip coupling inside the tape saucers. Unfortunately I have no service manual for Nakamichi 600 and can not remember quite how these adjustments were carried out on this model. I think that this felt slip coupling was built inside the saucer. Moreover, it was extremely rare when such adjustments had to be made because the value of the torque remained quite steady year after year. The most common reason when such adjustments was needed used to be if someone had used a spray bottle with oil, which is the most destructive thing to do in a tape recorder. Forgive me if I seem to be nagging about it, but the spray is very good if you want to spread oil wher it shouldn't be, and those slip couplings are one such place which must be very protected against oil. There may of course be other possible causes when this problem occurs, the tape wrinkle problem. On many tape cassettes the felt pressure pad may be lost, and this is a frequent reason to tape wrinkles because this felt pad has a role to play, not only for improving the tape pressure against the tape head, but also for the balance in the torque. Some Nakamichi cassette decks are equipped with a "pad lifter" but those decks are specially adapted so that they can play cassettes which has no pressure pads with no trouble from this, but this doesn't apply for the 600 model. Even a perfectly adjusted Nakamichi 600 might wrinkle the tape if the pressure pad is missing in the cassette.

The terms Contact cleaners and tape path cleaners should not be used interchangeably, and neither should the products! ARC S-721H is not a contact cleaner. It is a tape path cleaner, a no residue, no moisture, high volatility cleaner. I suppose if you have opened up a relay, and abrasively cleaned the contacts, you could use it to clean away the debris. Next, I have never seen a Fader Lube or Contact Cleaner that was NOT in a spray, so that is pretty much what everyone has to use. The pressure is needed to get the fluid where it will do good. The problem is that people tend to use way too much. The briefest spray possible is all that is needed. When I use it, I pack the surrounding area around the pot or switch with thin cotton rags (cut up t-shirts) to capture any over spray or leakage. After the briefest possible spray, which I acknowledge can be difficult, I switch to a can of compressed air or N2 and use IT insure the fluid has traveled where I need it. No mess, and less costly as well. Abuse of spray lubricant is indeed a great way to make a real mess if a tape deck. The right tools, used correctly, make for a good repair. Hammers and screwdrivers are proper tools for nails and screws. You wouldn't drive a screw in with a hammer. Please don't confuse user error with a blanket statement that all spray products are useless or dangerous.

I do recommend CRC 2-26 as a contact cleaner - it's a very good one. I would use it for instance to clean a rotary potentiometer (pot), or the R/P switch in a two head cassette deck (a 480, or a 500, 600 etc). I wouldn't use it on slider pots - they need a contact cleaner that includes a light lubricant. In servicing a cassette deck, various different fluids are useful for various different jobs. Solvents like ethanol are great for head cleaning - oils and light greases are useful to lubricate motor bearings, capstan bearings, eject mechanisms, classic transport cams, auto azimuth assemblies etc. Each part needs the right choice of lubricant. Contact cleaners are useful for cleaning contacts, but not for anything else. I’m not sure what Ingemar is driving at when he says (Message: 7 Sun, 12 Feb 2017)… “To completely destroy a Nakamichi, buy a "contact cleaner" spray CRC-2 from Sweden costing an equal of 15 Euro at Distrelec:”. Ingemar, if you use CRC 2-26 to clean contacts, you’ll end up with clean contacts. If you try to use it for anything else, then don’t expect it to be very effective. The link in Ingemar’s email (https://goo.gl/vwmWPU) shows a can of CRC 2-26. You’ll notice that it is supplied with a thin tube. This tube is used to deliver the contact cleaner to the contacts that you are cleaning – eg to inside a rotary pot or R/P switch. It’s there so that you don’t get contact cleaner on parts that don’t like contact cleaner. Various members in the group have their preferred contact cleaners – it just comes down to what is popular, respected, and available in your part of the world. For me, CRC 2-26 has been doing a great job for many decades – but only as a contact cleaner.

I do recommend CRC 2-26 as a contact cleaner - it's a very good one. I would use it for instance to clean a rotary potentiometer (pot), or the R/P switch in a two head cassette deck (a 480, or a 500, 600 etc). I wouldn't use it on slider pots - they need a contact cleaner that includes a light lubricant. In servicing a cassette deck, various different fluids are useful for various different jobs. Solvents like ethanol are great for head cleaning - oils and light greases are useful to lubricate motor bearings, capstan bearings, eject mechanisms, classic transport cams, auto azimuth assemblies etc. Each part needs the right choice of lubricant. Contact cleaners are useful for cleaning contacts, but not for anything else. I'm not sure what Ingemar is driving at when he says (Message: 7 Sun, 12 Feb 2017)... “To completely destroy a Nakamichi, buy a "contact cleaner" spray CRC-2 from Sweden costing an equal of 15 Euroat Distrelec:”. Ingemar, if you use CRC 2-26 to clean contacts, you'll end up with clean contacts. If you try to use it for anything else, then don't expect it to be very effective. The link in Ingemar's email (https://goo.gl/vwmWPU) shows a can of CRC 2-26. You'll notice that it is supplied with a thin tube. This tube is used to deliver the contact cleaner to the contacts that you are cleaning – eg to inside a rotary pot or R/P switch. It's there so that you don't get contact cleaner on parts that don't like contact cleaner. Various members in the group have their preferred contact cleaners – it just comes down to what is popular, respected, and available in your part of the world. For me, CRC 2-26 has been doing a great job for many decades – but only as a contact cleaner.

The seller said it's a working unit. Upon arrival, after basic cleaning I hooked-up my T-100 to the NR unit supplying a 400Hz (0dB and -20dB) to play-in sockets. With patient weating and adjusting the external controls so to have the level meters fixed at 0dB and -20dB(6 leds lighted up shown -18dB) for tape in for both Dolby B or without.Switching to Dolby C, the 0dB input signals also fixed on 0dB on the level meter but when switching to -20dB, both channels shown -30dB(only 2 leds lighted up).And I think there must be someway gone wrong with the Dolby C signal paths. How am I going to tackle this? -------------- next part -------------- An HTML attachment was scrubbed...

It adjusts how far up into the cassette the entire head and pinch roller mechanism moves . Might increase the roller capstan contact pressure enough to stop the wrinkling . Thomas.

These sensors are connected to controlling mechanics (or electronics) making those torques be continually adjusted while the tape amount is reduced on the left spool and grows on the right spool during play /record / fast winding, so that the tape tension is constant regardless of the amount of tape there is on each of the two spools. This is much more difficult to achieve on a cassette recorder but it exists similar solutions to achieve constant tape tension.

It also matters as what price range you prefer. If you don't need dolby C then that opens a lot more possibilities. Some people never use NR or just B. If you have a lot of prerecorded tapes then when they were made can also make a difference. Tapes made before 1982 were IEC1 and after 1982 were IEC2 and tended to be the better quality tapes made having HXpro, XDR and DIGILOG and recorded on digital bins, often with chrome tape at 120uS. Their boosted and better retained highs can make many Naks sound too bright. But sometimes the natural loss of highs can equalize that boost. Like many here, I own and have restored almost all the mainstream Naks. (All the ZX, LX, RX, BX, CR, CD, DR, 48x, 58x, 6xx, Dragon, 700,&1000zxl. ). I have my favorites, but there are potential issues with all of them, mostly related to aged parts and replacement substitute parts. Sankyo based transport decks that have already had the reel and mode motors replaced are often a good choice as Nak took a middle of the road IEC1 to IEC2 on many of them. Yet, my go to decks are usually "classic" transport decks. And though this is a Nak forum, there ARE plenty of excellent TOTL decks by other manufacturers that would be priced the same (or less) as some of the middle of the road Naks. Sometimes they make you appreciate Naks more, but sometimes they surprise you. This topic is discussed often on tapeheads.net. ------ Original Message ------ From: via Naktalk To: naktalk at lists.naks.com Sent: March 5, 2017 at 6:00 AM Subject: Naktalk Digest, Vol 168, Issue 2 Send Naktalk mailing list submissions to naktalk at lists.naks.com To subscribe or unsubscribe via the World Wide Web, visit http://lists.naks.com/mailman/listinfo/naktalk or, via email, send a message with subject or body 'help' to naktalk-request at lists.naks.com You can reach the person managing the list at naktalk-owner at lists.naks.com When replying, please edit your Subject line so it is more specific than "Re: Contents of Naktalk digest..."

Message-ID: <1fbafcca-2aa0-90f8-2a3c-4c9341dee40c@verizon.net> I'm a newbie to the list. CR-7A A130 S/N 07320 and S/N 08046 (2 machines). During power supply troubleshooting, came across what appear to be errors in the pin labeling and interconnects between connectors CN5 and CN6. Confirmed with continuity checks several times. My copy of the service manual has number O-860220A on lower right of back cover. I am unaware of other versions. Page 34: For CN5: Pin 2 is labeled " +5.6V " , should be " +12V " Pin 3 is labeled " -12V " , should be " GND " Pin 5 is labeled " +15V " , should be " -12V " Pin 6 is labeled " AC Power " , should be " -12V " An interconnect is drawn between CN6-1 and CN5-6. There is no connection. An interconnect is drawn between CN6-2 and CN5-5. There is no connection. Page 38: For CN5: The labeling errors for CN5 from page 34 are repeated for the Logic board end of the cable. The interconnect errors between CN5 and CN6 are also repeated. Diode D652 should be connected to CN6-3 only. At the power supply and logic ends the pin labels for CN6 are correct. Went through the list archives back to 2007 and did not see this mentioned. Would be hard to miss if troubleshooting the -12V power supply. Great list and contributors.

After powering up, loading and starting playback, the following symptoms appeared: 1. Low-frequency, almost sub-sonic motor-boating at very low levels from both channels. No music or other noise. 2. Both channel meters at full-scale. When stopping tape, all meter bars extinguished. No change with various Dolby selections. Switching to " Source ", both meter channels full-scale, even with audio input cables removed. On test bench, discovered -12v rail at + 0.44v. No fuses blown. Transport seems to be handling FF, REW, and Play OK without -12V. -12V goes quite a number of places. Doesn't appear any big filter electrolytics have been replaced in PS or main board. Will check with Cap/ESR meter. Anybody seen this one ?

Those cassettes are sometimes of the very lowest qualities of tapes, I have for instance had to play cassettes of the awkward brand Orwo, made in DDR, and other really bad brands. I have often noticed that single capstan decks are better to use, the lower the quality of the tapes. So I usually use my CR-3E Naka (double capstan) for almost all tapes, but when I have trouble with the very worst kind of cassettes, I instead use my CR-2E because it is a single capstan, and it can play the worst kinds of cassettes perfectly.

I have found the MR-1s slightly less fussy than the Dragons on bad tapes. I have two in the studio and one in the refrigerator--a trick I came up with to help tame squealing tapes--for an explanation see my ARSC Journal paper http://richardhess.com/tape/history/HESS_Tape_Degradation_ARSC_Journal_39-2.pdf I like the CR-4 as well. It is difficult to tell any difference among these three machine types on most of the horrid cassettes I get in to digitize. Of course, all the one-off music recordings I get (that I can legally copy) are transferred on the Dragons. I have also developed a manual azimuth adjustment for the Dragon, quite simple really, but the Dragon's electrically adjustable azimuth isn't wide enough range for some of the tapes I get in, so I use the MR-1s for those, as I prefer not to fuss with the manual azimuth adjustments on the Dragons, though I have.

I have, too, come to the conclusion that the squeeling some RTR tapes and tape cassettes produce is caused by lack of the lubrication, which was present when the tape was manufactured, but has lost its effect because of tape aging. Before I go deeper into this, we can have a thought about how large the space would be if we could cut up the tape in a C120 cassette in one-meter lengths, and lay all these lengths next to each other. The tape plays at the speed of 4.75 cm / sec, making the length of one meter after 21 seconds of playback. This means that after one minute of play, we have just passed 3 meters of tape. Thus we would get three meter lengths for each minute of the tape. The tape lasts for 60 minutes per side. The width is 4.3 mm. Thus, how many square meters does a C120 cassette contain? We don’t have to calculate this to understand that it really is a surprisingly large surface of tape inside those cassettes! This means that a three to four drops of oil that gets spread across such a large area is unlikely to make the surface particularly "oily". At least not if you could get a very even distribution so that the oil settles everywhere on this surface so the tape would not slip at all, but the oil would actually prevent the squeaking. The squeeking is similar to what happens when a violin string is affected by the bow. The worst you could do against a violinist would be to put a little oil on the bow – please never do that! I have used this oil treatment for many years with successful results when it comes to squeeling tapes. I start by fast winding through the tape a few times so that the full spool inside the cartridge will be very evenly threaded from end to end. Then I disassemble the cartridge so that the two spools inside are accessible. Then I use a small oil jug with a narrow spout, and I wipe out three thin strings of oil (as in propeller shape) upon the tape cake from the tape’s inner edge to the periphery, and note here that it is the best to be more cautious in the inner end of the cake so that there will be a little less oil there. Then I wipe with a fingertip on cake’s upper side so that the oil is evenly distributed on the cake. After a while, most of the oil will have "crept into" the tape turns, and the surface of the cake looks almost dried out again. Then I wait for a few hours, and when the surface looks really dry I assemble the cassette again, and fast-wind the cassette to the other extremity. Now and then, with hours between I again wind the tape to the opposite end, and let the cassette rest in between. This can last for several days per cassette. The idea is that the capillary sucking should make the oil to be spread very evenly like an invisible film on the surface of the entire tape length inside the cake, and the more time that is given the better it will be. You have to wait a few days before trying to play the cassette, otherwise oil might have become more accumulated in some places on the tape, and if so, it may happen that the tape could start wowing or even stop if it is too slippery . It may also happen that the squeeling returns either because the oil has not yet been spread enough widely, or that we used a too small amount of oil. This can need a lot of patience and you may have to give the tape cake a little more oil and more time. But it will work, it has done so for me, every time. Which oil? Well, certainly not cooking oil, but ordinary lubricating oil, machine oil, or whatever.

Hess via Naktalk) Date: Mon, 6 Mar 2017 16:37:49 -0500 Subject: [naktalk] Choice of decks In-Reply-To: References: <6d357dg51vmf5f883adwxe1d.1488815525587@email.android.com> Message-ID: Hi, Ingemar, The point that I tried to make in my ARSCJ Paper (linked in the quote below) was that the original amount of lubricant is quite often still there. It seems as if it has gone away, but the reality is that the tape needs more lubricant after it has aged. The cold playback technique helps with tapes where the tape's glass transition temperature (Tg) has degraded. This is the temperature at which an amorphous solid goes from glassy to rubbery. When manufactured, the coatings had Tg well above room temperature. The one tape whose coating's Tg could be measured, it was around 8 °C. So, if the tape is cooled to 4 °C and held there until it is all at that temperature, the tape coating surface will be much more glass-like and play without squealing. The squealing is actually microscopic start-stop jerks as asperities (high points) of the tape interlock with the same on the heads and then break free. Two liquids discussed in my paper for lubricating tapes for playback are isopropyl alcohol and decamethylcyclopentasiloxane (D5). D5 is the stuff that goes into shampoos and soaps to make them slippery. It evaporates into thin air after a while, so you don't run the risk of damaging a tape deck by over-lubricating places that shouldn't be lubricated. Lubricants such as Krytox should be avoided as that will get over everything and not be removable. Machine oils are not a good choice for the same reason, as removing them is hard, they build up, and they attract dust. I have looked into this long and hard and the most effective techniques (depending on NEED as most work on different problems) are: baking, cold playback, and adding D5 lubricant. Note that isoprpyl alcohol can replace D5, but read Marie O'Connell's paper on my website before trying it and see the work she went to for using it on reels. Other methods can work in specific cases, but it is very difficult to predict success. One that probably needs to be investigated more is vacuum desiccation. Cheers, Richard Marie's article: http://richardhess.com/notes/2006/03/09/wet-playing-of-reel-tapes-with-loss-of-lubricant-a-guest-article-by-marie-oconnell/ My tape degradation paper (as linked below): http://www.richardhess.com/tape/history/HESS_Tape_Degradation_ARSC_Journal_39-2.pdf On 3/6/2017 15:29, Ingemar Lindqvist via Naktalk wrote: > Thanks to Richard for his text about the problem with squeeling tapes. > > I have, too, come to the conclusion that the squeeling some RTR tapes > and tape cassettes produce is caused by lack of the lubrication, which > was present when the tape was manufactured, but has lost its effect > because of tape aging. > > Before I go deeper into this, we can have a thought about how large > the space would be if we could cut up the tape in a C120 cassette in > one-meter lengths, and lay all these lengths next to each other.

But I find many faults when I try to adjust for the various tapes. One is that it is no recorded signal on the metal setting at  normal speed left canal.   But for start I enclose the photo of the meters as the signal bars appear when in source and cal. engaged.   I´m not good at reading the instruction manual that I of course have downloaded. So please advise me at what point I should adjust to get the correct signal strength for both left and right. When I check output strength that corresponds to the meter difference, but strength/meters are also supposed to be at 0dB. Also enclosed a picture of the internals. Maybe someone can point to the area and what to adjust, or change? Birger -------------- next part -------------- An HTML attachment was scrubbed...

The Decks who are build near like REEL decks are the 700/1000 Series made from 1973 to 1979. My favorite is the 1000II. It sounds very open and strong. Showing his analogue meters up to 10db. There are no switches ore buttons who get erased on lettering by using them over the years. ( Dragon ) The Decks with the classic tape transport are all very similar. Exe-pt the 1000ZXL. It is, the best recording Deck. No matter how cheap the cassette tape was. The recording sounds like the original. Lets say 99%. Depending what amps and speakers you use to search for differences. The plastic made classic transport needs great care when the Decks will get shipped. It can break on his hubs. The tape heads from this transport should last a little longer because of the pad lifter ( 1980 ) So any Nakamichi has his good and less benefit sides. The main Controls of the 680 Series are better than on ZX-7 or ZX-9. But on ZX-7 we don´t need a screwdriver to set the record bias. analogue regards ... clooock ....... makes the two inch solenoid by switching on 1000II play, Gerhard / Vienna Am 04.03.2017 um 20:37 schrieb Roland via Naktalk: > I have two perfectly working Dragons and a 600 that is working now > thanks to the help of a fellow Nakker. > > I've own a CR7A (used) and a BX300 (new) in the past but now > looking for a middle of the road choice. > > I think it'll be in the 680 or DR series.

All is good for me in MadCity WI USA. With interest, I've been reading the recent postings regarding the Nak Marathon Tapes projects from way back 13 years ago. Fond memories and renewed listening for me during the last month or so. The original Marathon Tapes project was so good in its digital disc format, intended to be duplicated to cassette tape by those contributors receiving the discs from Carlos Guzman (aka The Tape Man). Untouchable, in my opinion, its an historical document that stands on its own merit for contributor content. For those of you unfamiliar with the original Nak Marathon Tapes project, we have a web page that covers essential musical tracks, some additional contributor bio info, and other supporting documentation. Recently added (by your truly), a repro image of the certificate showing authentic ownership to the limited edition distribution. Web link to view that if you're interested: *http://www.angelfire.com/wi/blueswapper/nakmarathoncert.html * Also, I'm resurrecting the Marathon Tapes Mk II project web page, long ago posted as unfinished, so its time to get that together with complete music track info for disc two, the San Francisco NakFest scene from early 2004. If you San Franciscans are still in-touch, let's connect and finish the page content You can contact me directly..... *http://www.angelfire.com/wi/blueswapper/nakmarathon2004.html * All for now, continue to enjoy your gear and music !!!

The circuit board includes a ±10V regulator, a +12V regulator, and a power mute circuit. The circuitry is all discrete, and is all pretty basic stuff that would be easily repairable. The transformer is also nice and simple – just one centre tapped secondary winding, and a few primary options were offered to suit different mains voltages. So when you say it needs a new PSU, have you worked out whether it’s the transformer or circuit board that has the problem? I would imagine that you would be able to find a local electronics tech to repair the board or point you in the right direction for a replacement transformer if that’s the issue.

Make sure amp is turned off though before connecting the MP3 player to prevent thumping. There are more elegant ways but that's the quickest to get you going. I am working on an external relay volume control that would incorporate an aux input but not getting much done on it.    Cheers, Rainer On Sat, 25 Mar 2017 09:03:41 -0400, Mike kehr via Naktalk wrote: Hello All, I am looking for a way to add an AUX input to my TD-500.

It's a long time since I've played with a 630, and I can't remember crosstalk from the FM tuner being a problem. A quick look at the schematic shows that Nakamichi didn't do a lot to try to prevent crosstalk from the FM section. The input signals that aren't selected on the Function PCB are shorted to ground, but the tuner is still powered on, and its signal is clearly bleeding through in all three of your devices. It would be possible to insert a switch that simply removes power from the Tuner Section when you are using other inputs, and this could be mounted on the rear of a 630, but it's not really a nice solution. If you have any control over the amplitude of your AUX signal, you might find that the crosstalk from the tuner is less of a problem if you keep the AUX input as large as possible. There aren't any active stages between the AUX input and the Volume Control, so a large AUX input amplitude won't actually cause signal overload - it would just require a low setting of the Volume Control. You could also try cleaning the input selector switchbank - maybe over the decades the contacts that short unwanted signals to ground have become dirty. Good luck with it. Regards John Gipps 1.

A little while back it was ok'ish (some wow/flutter problems on certain tapes), but then it stopped working entirely. When switching on the power led comes on and that's about it.

This brings be to several questions: 1) Can anybody confirm that it's "only" a light bulb? Anybody an idea where to get a replacement and how to get it switched out? 2) If I do not remember correctly and the described behaviour is a more serious issue (e.g. control board) I'm not sure if I want to spend a lot of money on to repair it.... Especially As I would like to get the wow/flutter issue fixed as well. 3) Are there (still) any trustworthy repair shops left in Germany (or Europe) who also might be able to get replacement parts for the rubber things (Capstan, pressure rolls, ...) 4) Or, alternatively is somebody on the list (more) enthusiastic about getting and repairing (or slaughtering ;-( ) the RX505? 5) In the latter case I would have about 25kg of well kept tapes (TDK-SA) Maxell XLII from 1990-2002) to sell off as well. Almost all of them prerecorded, mostly only once on the RX505, only played on the RX505. I hope I can get some repair pointers on the list or if someone is interested in the deck or the tapes just contact me. Thanks for any advice!

The RX-505 is new enough that it doesn't use any incandescent lamps other than the cassette well illumination. If it really only lights up it's probably a power supply problem. There are several sections of the supply and at this vintage the power supply electrolytic caps are a likely guess. If one of them is shorted it will take that rail down. I don't know of a good shop in Germany but Bowers & Wilkins in the UK has been working on these decks since they were new and is a good bet.

It is a small version of a 1000zxl . Also a beast to repair. At first the transport must go through a overhaul job. New grease and oil, new belts , new idler and calibrate the transport with the 1khz tape from nakamichi together with the 15 khz azimuth tape. As soon the transport is ok , you can through the electronics of the machine. Not a easy operation the 700zxl.

The ZX-7/9 is longer than the Dragon/680 ones, so harder to come by, and I do not have any spares of them Luckily, they are all typically able to be shortened at least 12mm and still function fine. It is a bit involved, but not rocket science. I disassemble the plastic connector carefully, noting which side is "up".The cable can only be shortened in increments equal to the spacing of the segments of the blue plastic. Each segment had a pair of pins or nubs that seat in the plastic end connector. Then using various dremel attachments, I cut the cable equal to the segments removed and duplicate the end shape and slotted hole in the cable. It is tiny work, and at my age I use a magnifier. As long as too much doesn't need to be removed, I have had a 100% success rate. Perry Sent from XFINITY Connect Mobile App -------------- next part -------------- An HTML attachment was scrubbed...

I'm not a super-tech, so take it easy on me. I just bought a Nak Cassette deck 1.5, and ended up replacing the motor, as it had seized completely. Now that it has been completed, the deck is in really nice shape and sounds great. But there is one noticeable issue: When powering on the deck (from cold) and playing a tape, I notice that the left channel is down quite a few db in level, but if I wait about 8-9 seconds, the audio slowly creeps back in. Initially, I thought it was tape curl, but I put in the mirror tape, and the path looks great. If I rewind the tape and play it back, it sounds fine. If I leave the deck on all the time, it will work perfectly, but if I turn off the deck and leave it off overnight, the issue comes back. I'm suspecting some sort of cap or transistor is bad...but hoping someone on this list has run into the issue. :) Any hints or suggestions would be mighty appreciated. Thanks!

I used to use CM100s and CM300s myself, and always found it inconvenient that the CM300 required a hard to get 9V battery, whereas the CM100 used a cheap and easily available 1.5V battery. I had a look at the circuitry inside both microphones, and tried a simple modification on the CM300 so that it could be powered by a 1.5V battery. It worked very well indeed, so all my CM300 microphones were modified to use 1.5V batteries. If you are interested in this as an alternative to sourcing the 9V batteries, then I will search through old notes and find the details. From memory, I'm pretty sure that the changes were minimal, and only involved changing the value of one resistor - or possibly two - it was a long time ago. From memory, the CM300 was released first, and the CM100 followed. I think Nakamichi may have received feedback from end users that caused them to change to a 1.5V supply for the CM100. Certainly, the tiny output voltages of these microphones does not require the use of a 9V supply, and from memory, most of the available power supply voltage in the CM300 was thrown away over resistors in series with the amplifier.

I've established that I looked into it for a customer in May 1989 and then changed my own CM300s in March 1990. I know that I will have details including a CM300 schematic in work notes from those dates. Will email you as soon as I find the notes. I'm reminded just how good the recordings were using the CM series microphones, Black Box Series mic preamps, and ZX7 and ZX9 decks. I was recording light opera for a G&S group I belonged to, and used the Nak "Three Mic System". I recorded on TDK SAX and used Dolby C. I thought the results were quite remarkable.

I have a service not that the capstans were sluggish starting when I got it, but I lubricated it with some Studer-approved lubricant and that seemed to cure the problem. After using it for several years, in the middle of a session (I think it was the start of a side) the machine didn't start. I don't know if having it in a frost-free fridge means anything. It's an early issue MR-1 from about the third quarter of 1987. I was able to finish the job with one from 1985. The two in my studio are from 4Q88 and 2Q93. Cold playback is a way to play some tapes that squeal at room temperature. I premiered that in my 2006 paper: http://www.richardhess.com/tape/history/HESS_Tape_Degradation_ARSC_Journal_39-2.pdf What I'm asking for is a few off-the-cuff experiences in where you found a solution to a similar problem. Since both capstans don't spin, I don't think it's the belt. Since the capstans were spinning fine and then stopped, I don't think it's a lubrication issue, as those usually creep up on you or appear after a period of disuse. Thanks!

The nature of this squeeling effect reminds very much about what happens when a violinist strikes the bow over the violin strings. To improve this effect the bow needs resin, and this is also a common ingredient in the binder mix of the tape, so it is not very strange that some tapes squeal when the lubricant has dried out. It would be a disaster to the violinist if someone added lubrication on the bow's strings. No sound would be beard when the bow was striked against the violin strings after such a sabotage! We seem to be agreed that the main reason to why some tapes cause this squealing is the lack of lubrication. So why not add new lubrication? I have tried this and to successful results. The baking method, however, I have tried it but only to the result that the squeeling became an increased problem. I tried baking at 60 C, 70 C, 80 C and at 90 C. I tried to play the tape between those baking tests, but it only got worse the higher the temperature. After this I tried the lubrication method instead, and this was successful.

It is a good one. The problem is that in work done at the Paris Museum of Natural History by Benoit Thiebaut (as part of the Prestospace Project), he found that the tapes which had SSS also generally had a proper amount of lubricant in them. The lubricant had not disappeared. What happened was that the required amount of lubricant appeared to increase, but in reality, flooding with lubricant merely masked the problem that the binder had deteriorated and had many more components in the "sticky" molecular weight range. In some instances, researchers found that the glass transition temperature (Tg) of the coating had fallen to +8°C (or perhaps less). In these cases, at room temperature, the mag coat was more like sticky rubber, but it hardened up again when it was chilled, which was the genesis of the cold playback technique that I introduced in my paper. The very rough molecular weights are: good binder: 50,000, sticky binder: 5,000, and lubricant: 500 g/mol. These show up as spikes on the mass spectrometer analysis. Degraded tapes show a major spike in the 5,000 region (again, very roughly). Baking does not work on all tapes, and should not be universally applied. While longer baking times are acceptable, higher temperatures are not. 54°C is the highest temperature recommended, and I generally bake closer to 50°C. Tapes which don't respond to baking can have their problems exacerbated by baking. Many of us are baking tapes 2-4 days while one researcher with very large reels with no windows in the reel to allow good circulation is baking for 30 days. So, there are three approaches, depending on the original tape stock: baking, cold playback, or adding lubrication. The trick is to know which one is best for a given tape. If it's an Ampex back-coated tape or a 3M back coated tape other than 206/207/208/209 then baking should work. If it's a Sony tape, if it is back-coated, then baking seems to work. If it is not not back-coated (like PR-150), then lubrication with decamethylcyclopentasiloxane should work. For cassettes, my first choice is to try cold playback as many unbranded cassettes are Agfa tape which seems to respond to that and does not respond to baking. Interestingly, I had an Ampex DAT that did respond to baking. I keep a semi-current discussion of tape-specific treatments here: http://richardhess.com/notes/formats/magnetic-media/magnetic-tapes/analog-audio/degrading-tapes/ (last update July, 2017) Here's a link to my paper: http://www.richardhess.com/tape/history/HESS_Tape_Degradation_ARSC_Journal_39-2.pdf Cheers, Richard On 2017-08-20 1:27 PM, Ingemar Lindqvist wrote: > Hi Richard > > I have read your pdf document, and I find it very strange that you > seem to be very aware that the main reason to SSS syndrome (squeeling > tapes) is that the lubricant that was added in the manufacture of > tapes, has through the years been dried out.

Hess for your answer. I am sorry that I haven't responded sooner. I feel very great respect for the very great knowledges you have shared with us. Thank you! When I have tried the baking method, I have never had any successful results from it, and it possibly could be because I have performed this baking during too short times. Instead I have tried the lubrication method - without ever hearing or reading about anyone else describing this method. I only came to think about the likelyness of the violinist and the bow striking against the violin strings. One trouble with the lubrication method is that it is very far from a "quick fix" because one always have to spend much time to test the amount of lubrication, step by step for every single tape. It also needs several days for resting while the capillary suction spreads the lubrication oil to all surfaces of the tape. During those days it is good to rewind and wind the tape reel frequently from one end to the other. Some times it has happened that I have given too much lubrication, which of course results in noticeable tape slipping resulting in wow/flutter, or in worst case that the tape smears against the surfaces of the tape heads and other parts, and stops the playback. But even in those cases, when such things has happened, I have always managed to get a good result, later on, after letting the tape reel rest a much longer time. I have also noticed, that after I have had a successful digitization of a tape after the lubrication method have been used, that the same tape can make squeeling sounds much later if I again try to play that tape. So, it is obvious that a tape roll can "swollow" a surprisingly large amount of lubrication oil without being damaged of it. I have only used very unsofisticated "sewing machine oil", but luckily I have never needed to use this method on any DAT tapes or video tapes, only analog audio tapes, RTR or cassettes. I admit that it would be extremely risky to try the lubrication method on squeeling video or DAT tapes because of the rotating drum playback method.

Nevertheless, for academic reasons about a month ago, I decided to try isopropyl alcohol on one such tape. This was after I found that just forcing room air conditioning through my deck didn't solve my problem. I removed the windows out of the cassette and lightly applied alcohol with a cotton-tip swab to the outside of the pack as the tape wound off the supply reel. I simply leaned the swab tip against the outside of the supply reel and used another swab to regularly load (every second or two) the first one with more alcohol and nudge the first one as necessary to keep it against the tape. Surface tension of the alcohol actually appeared to drag the tip along pretty well most of the time. I also first applied alcohol to the whole pack by lightly dragging the swab across the side of the pack, letting the alcohol wick into it, repeating a few times as I rotated the pack a full cycle. Not sure how effective that was to do though. Pretty painstaking, thanks to having to stop and restart playback again very often (hey, this was pretty trial and error!), and edit a final product together later. But it was low fidelity oral history material that lent itself to that pretty easily. Would not want to repeat without a methodology that required less continuous human interaction. And there are better lubricants as Richard suggests. Anyway, that's just some food for thought. Perhaps others care to comment. I felt I didn't have much to lose in this case, keeping an eye on my heads as I went of course. Pretty much a one time thing in this rough form. I'm just feeding my findings to our collective brain here. I will likely count on cold play next time, or a better lubrication system as I said earlier, all depending on conditions! -Karl Karl Fitzke Audio/Visual Specialist 214 Olin Library Ithaca, NY 14853 607-255-5521 karl.fitzke at cornell.edu ________________________________ From: Naktalk on behalf of via Naktalk Sent: Tuesday, August 29, 2017 6:00 AM To: naktalk at lists.naks.com Subject: Naktalk Digest, Vol 173, Issue 6 Send Naktalk mailing list submissions to naktalk at lists.naks.com To subscribe or unsubscribe via the World Wide Web, visit http://lists.naks.com/mailman/listinfo/naktalk or, via email, send a message with subject or body 'help' to naktalk-request at lists.naks.com You can reach the person managing the list at naktalk-owner at lists.naks.com When replying, please edit your Subject line so it is more specific than "Re: Contents of Naktalk digest..."

Kind Regards, Bala Ganesh On 21 Aug 2017, at 5:40 am, Richard L. Hess via Naktalk wrote: Hi, Ingemar, Thanks so much for the question. It is a good one. The problem is that in work done at the Paris Museum of Natural History by Benoit Thiebaut (as part of the Prestospace Project), he found that the tapes which had SSS also generally had a proper amount of lubricant in them. The lubricant had not disappeared. What happened was that the required amount of lubricant appeared to increase, but in reality, flooding with lubricant merely masked the problem that the binder had deteriorated and had many more components in the "sticky" molecular weight range. In some instances, researchers found that the glass transition temperature (Tg) of the coating had fallen to +8°C (or perhaps less). In these cases, at room temperature, the mag coat was more like sticky rubber, but it hardened up again when it was chilled, which was the genesis of the cold playback technique that I introduced in my paper. The very rough molecular weights are: good binder: 50,000, sticky binder: 5,000, and lubricant: 500 g/mol. These show up as spikes on the mass spectrometer analysis. Degraded tapes show a major spike in the 5,000 region (again, very roughly). Baking does not work on all tapes, and should not be universally applied. While longer baking times are acceptable, higher temperatures are not. 54°C is the highest temperature recommended, and I generally bake closer to 50°C. Tapes which don't respond to baking can have their problems exacerbated by baking. Many of us are baking tapes 2-4 days while one researcher with very large reels with no windows in the reel to allow good circulation is baking for 30 days. So, there are three approaches, depending on the original tape stock: baking, cold playback, or adding lubrication. The trick is to know which one is best for a given tape. If it's an Ampex back-coated tape or a 3M back coated tape other than 206/207/208/209 then baking should work. If it's a Sony tape, if it is back-coated, then baking seems to work. If it is not not back-coated (like PR-150), then lubrication with decamethylcyclopentasiloxane should work. For cassettes, my first choice is to try cold playback as many unbranded cassettes are Agfa tape which seems to respond to that and does not respond to baking. Interestingly, I had an Ampex DAT that did respond to baking. I keep a semi-current discussion of tape-specific treatments here: http://richardhess.com/notes/formats/magnetic-media/magnetic-tapes/analog-audio/degrading-tapes/ (last update July, 2017) Here's a link to my paper: http://www.richardhess.com/tape/history/HESS_Tape_Degradation_ARSC_Journal_39-2.pdf Cheers, Richard On 2017-08-20 1:27 PM, Ingemar Lindqvist wrote: Hi Richard I have read your pdf document, and I find it very strange that you seem to be very aware that the main reason to SSS syndrome (squeeling tapes) is that the lubricant that was added in the manufacture of tapes, has through the years been dried out. The nature of this squeeling effect reminds very much about what happens when a violinist strikes the bow over the violin strings. To improve this effect the bow needs resin, and this is also a common ingredient in the binder mix of the tape, so it is not very strange that some tapes squeal when the lubricant has dried out. It would be a disaster to the violinist if someone added lubrication on the bow's strings. No sound would be beard when the bow was striked against the violin strings after such a sabotage! We seem to be agreed that the main reason to why some tapes cause this squealing is the lack of lubrication. So why not add new lubrication? I have tried this and to successful results. The baking method, however, I have tried it but only to the result that the squeeling became an increased problem. I tried baking at 60 C, 70 C, 80 C and at 90 C. I tried to play the tape between those baking tests, but it only got worse the higher the temperature. After this I tried the lubrication method instead, and this was successful.

Typical current on the bias is supposed to be around 350mA, so nothing actually difficult to read on todays modern gear. I only have a typical Fluke 189 and it works perfectly that way, though I rarely use it that way, and stick with the precision 0.1ohm resistor. The original instructions MAY have been specific about the resistor for reasons other than ease of measurement, but since there are no warnings, I can't be sure. Care must be taken not to switch in and out the leads while the unit is powered up. I know from actual experience, unfortunately, that opening and closing the bias circuit with the leads can cause some of the transistors in the bias circuit to fail, presumably from the surge. Not fun troubleshooting them. Sent from XFINITY Connect Mobile App -------------- next part -------------- An HTML attachment was scrubbed...

One of my RX-505s always reverses about 7 seconds after the music stops on the last song once the amount of tape remaining is below a minimum length. This is only a problem on the few tapes where the first side is recorded within maybe 60 seconds of the end of the tape. The result is that B side starts playing already in to the first song. It is not a tape stop issue. If I turn off the autoreverse, side A will play until the tape stop sensor is triggered at the end of the leader. It is as if the deck is measuring the rotation of the hubs as slower that it is, which I know will trigger the auto reverse if no music is playing. If I switch to the Large Hub setting it will switch sooner after the end of the song, so I know that logic works. The switch from Small to Large simply grounds the logic pin in the logic IC. I know I have to check the pulse counts, as they may be low due to a tarnished/bad reflector, which would fool the logic in to thinking the hub is turning slower than it is. But it is so close to correct, I doubt that is the issue. Has no one seen this before??

I failed to remember that in order for the autoreverse to operate correctly in playback mode, the Auto Fade for record must be turned off. I had discovered this idiosyncrasy years ago, and since I basically never record with the 505, it is always off. But after I performed a recent checkup, including the record functions, I inadvertently left it on and caused the confusion to myself.
