That drive system is bit prone to misalignment. I have run into them before. If you disturb the motor mount the idler/flywheel and the motor shaft may not be at perfect right angles to one another, causing flutter as the motor crabs along the wheel edge. Check that out if the wow & flutter continue. In some cases you can let it align itself by loosening the mounting bracket screws and letting the motor pull it self into a good position. You can usually feel the motor vibrating when it is out of alignment and just move it around until least vibration is felt, then tighten the screws while holding it.
Thanks for the video. I used to work for a company called Teletape in London. We specialised in all tape formats. I got one of these machines as a staff bonus along with a couple of expensive microphones from Sony. I think I took it out half a dozen times and never really used it. I still have it with it's box and it is in mint condition. I know the reporters that bought them used to bash them about a bit. A couple of things worth mentioning. The belt can be removed by taking out the one screw that hold down the capstan. The belt slides under the other plate and loos back over the spindle. The Alsop Cleaner was designed to be used in fast forward or rewind and not play as far as I remember. As you say these machines are a nightmare to take apart. I gave up with my other portable recorder the WM-D6C. That one is also still in a box somewhere. I will have to see if I can find them and check them out . I think I might still have some Panasonic azimuth test tapes. Thanks agin as this is not quite so scary now. PS when I took stuff apart I used to draw all the elevations and name them top front bottom etc and place the screws in holes in the position of the sketch. My engineer used to call screws let over "Pocket Screw" Regards Jeremy Travis
Great repair as always. I use the Allsop head cleaner on my decks it works fine, even the head cleaning part. I have a different make as well, that doesn't work as there is too much pressure on the head.
Well I am in Canada. We have been on the metric system for 50+ years here. I still think in inches and feet, and farenheit only because so much or our stuff is american and they still deal with that old obsolete method of weights and measures. The metric system is so much simpler, but when your biggest trading partner still uses the old system we have to be able to think both ways.
Thanks for this video! I just pulled out my gently used TCD5M, which I bought new in the early 80s, but it has been sitting for maybe a decade. Everything works except the fast forward, so I can see it must be the same the same belt you replaced. Your instructions are clear and I won't have any trouble with it. But I'll need to find a belt!. Where can I get one? I can probably find a parts list for the machine, but I might do better knowing the actual size of the belt. It's a great relief to know it is that simple! Rich
I’ve got one of these I can’t believe there was a repair video one tube onit . ITT cost @$550. In 1976, it used to make AMAZING RECORDINGS. IT HAS THE EXACT SAME PROBLEMS
The reason they have w&f issues is that the rubber ring on the flywheel that the motor engages with deteriorates and the motor starts to slip on the surface. There's has never been a replacement ring for it (Sony would have had you replace the whole flywheel when they were fresh and still existed), so these decks will continue to fail more and more until someone does something about it. I have had one for about 20 years, and it sounds perfect on newer, smoother tapes, but it has trouble when I put an old tape, or one that gives any real resistance. There's a guy I know of that will replace the rubber for you, but you have to take it out of the deck and send it to him, and it's expensive; he has to remove the old rubber, bond new rubber to it, and then turn it down on a lathe to the correct thickness and taper angle.
Do you have any idea how to tell what year they are produced i just got one with the serial number 58752 in the battery compartment and this model was made from 80'-2005
Dave, I really enjoyed this tutorial. I've got a couple of Marantz Superscope cassette recorders that are a bit bigger, but similar to this. I've got to replace the belts and this repair gives me an idea of what is involved. Sorry to hear about your cat allergy issues. Maybe you can get an allergy shot? Also, maybe you weren't allergic to cats at one time then grew into it, so maybe you'll grow out of it? Hopefully... Regards, Tom
I like the slatey metal it has . Sponsoring a Channel , this is the on I would do first , it would be worthy no doubt about it . Collecting tape decks is more needed than getting extra tapes ! Tapes outlast the decks overall . Tape decks can ripple the side of the tape somehow , not to sure what that is yet . its a first to me
Yea, pretty interesting just how sensitive a scope can be. My DSO has a filter that will clean the signal up a bit, but it will not reject a signal all together like an AM carrier. It can filter out some of the noise from lights and stuff like that.
C MJ My scope has a bw limit of 20 megs switch but the carrier is 1440 kHz and the antenna is on the other side of the garage. It puts out 400 mW which is not much but enough to get into devices that are close.
Somehow at the end of the video I can hear a LOT of wow and flutter from the playback and a little bit less on the recording test. Is it just me or is this thing a little bit off?
The unit is very old, needs lubricating, greasing, all belts and tyres changing - alot of work. The client won't pay that kind of money. This man is keeping cost down for customer.
Hi there ! Thanks for your tutorial ! I recently aquired this recorder, I done some cleaning operation and belt replacement. The sound is good and all imputs and outputs are functionnal. I have a problem. When I plug the power, many times I can see the vu-metter light turn on by itself and in this case nothing works (and the light stay always on). If, when I plug power the light stay off, the device works (including the lights when I press the light button). Do you have an idea about this problem ?
@@markanderson350 More like $500 when I bought mine in '82 or '83. But was worth every penny. I don't believe you could get a better cassette machine, despite its size.
Hey. Great video. My son and I used your video to replace the belts and when we were done we put the thing back together, and the record light was permanently on and tapes won't play. They will turn but there is no sound. Any idea what we did wrong?
Forgive my ignorance but there is more than just one belt in this machine. The kit I received has 3 belts and they're all way thinner then the one you used. If one is bad, is it not likely they are all in need of replacement? For a video with overhaul in the title I was expecting to see all of the belts replaced. Getting to them and properly re-assembling would have been very helpful. The one you did was the easiest to get at and pretty obvious how to replace. The real utility of videos like this is the difficult stuff that non-techs need help visualizing or explaining the way something works or how to avoid pitfalls along the way. Any hack, like myself, can remove screws take off a back cover and put in a belt. That said, I appreciate your videos and I've been able to repair and maintain my equipment (DAT/Digital8) by watching your channel so thanks.
I don't have any vintage video games. I never got into gaming and never bought a console. To this day I don't gave. I have a PS3, but I bought that many years ago as a bluray player as at the time PS3 was 699 and a stand alone bluray player was 1000.
You should hear this thing through headphones or a good system they where considered portable nakamichi level recorders, it has metal, limiter, Dolby b and recorded music amazingly!
You have good skills, but just using any (close) replacement belt can do damage to motors and W/F will never be to manufacturers spec. At least you got it going and the kit is very old - your charges must be reasonable too, so can't complain! Well done!
Why wasn't all three belts changed at the same time since it took quite some work to open it ? I can understand if the customer didn't ask for that but.......what a work to access just one belt ! The other two will go broken also soon. ( after thirty years of drying) Nice video ! I bought my TCD5M new in Japan in `79. It has a broken belt and I'm going to change all three at the same time after seeing this. Thank You 12voltvids !
Well you are when I make 30.00 to change a belt and a belt these days costs 10.00, changing 3 would cost 30 in parts. Are you about to put 30.00 in parts for something you make 30.00 on. Remember the vast majority of the things I fix for others are things they want to spend the absolute minimum on, so they can sell them on fleabay as a working device as opposed to a broken one. So I have to do what the owner asks. I can quote 30 to change 1 belt or 60 to change all. Remember that they could be paying shipping both ways too depending if it is a ship in or not. Also, not a the belts may need changing. Certain ones wear faster then others and some are made of different materials. I have a tape deck that one belt turned to black mush and the other one is fine 30 years later. Different manufactures of the different belts at time of manufacture. Some last forever, depending on what they are made of. I do exactly what clients ask for. There was a time when I would change all the belts and charge for them and I would get more people accuse me of padding the bill. Like the time I took my old car to a mechanic to get the water pump changed because I didn't have a special wrench to access 1 bolt and he changed my fan belt and added it to the bill. I had just put a new belt on myself. Or the other mechanic that worked on my other old truck. Took it for a oil change and he changed all the spark plugs and billed me for it. Never went back to either. I do exactly what I am asked nothing more.
@@12voltvids Thank You for answering me and also for doing it so quick ! I couldn't have asked for a better answer ! This is the world we are living in. I would have asked You to change all three belts in my my tape recorder knowing it would have been fine for the rest of my life.I would have payed the extra dollars. I'm in Europe so I rather do it myself. I have been through the same "oil changes" as You described were they changed the spark plugs and NOT the oil.I wish there were more people like You that fixes tape recorders to us people who still uses them. I just bought the three belts from a supplier in Germany with the original Sony part numbers. I will have them here in a week or so.I hope You're okay there. We see the riots that's going on in the US and the Covid-19 situation also. Have it well 12voltvids!
@12voltvids I just purchased a Sony TC-D5M and it is having the exact same issue - is there any chance I can mail you my device and pay you for repair? I can’t find your email or contact.
Great! thank you very much for posting this. Mine has stopped erasing all of a sudden. Do you know what it is and how to repair it? i actually have the TC-D5 PRO !!, doe sit make any difference when changing belts or repairing the erase thing? It also makes a noise sometimes on the left channel, especially when playing, and it s a very annoying noise that makes the arrow go crazy. Could that be repaired too? thank you very much in advance for your reply.
@@markusziman363 check the wire going to erase head. They do break from time to time as they bend every time you press play. Scope the head and see if there is a bias signal. If no bias then either the wire is damaged or bias oscilator is broken.
Smashing :-D it sounds like the rec/play head still produces hf audio nicely :-D. They put a lot of work in to that unit, mostly metal mechanism, that would not have been cheap in it's era for sure. Love the meters, really classic design. ' Dam shame you are alergic to cat dander, if you love stroking them i think there are alergy tablets that can lessen the effect, or you could have a proxy eg your wife do the petting lol :-D.
I have one of these, they are great cassette decks, amazing performance if it is in good shape, the wow and flutter seemed waay off on the video tho, mine has 0.06% like when it was new, that poor thing must have spent waay to much time without use.
Yes but it will come back with use. First it is rather cold in the shop this time of year, but once it has warmed up a bit, and run for awhile it should settle down nicely.
@@12voltvids True. Mine made a sort of grinding noise at first but after some use it quieted down nicely. Further cleaning of wheels and tires could't have hurt. I can't remember when I last used it. It could have been 20 years ago. Bought in '82 or so, the thing is a jewel.
@@12voltvids Cheers to the late night lifestyle (if you're American). Would you go D5 or F5? Sounds like either? PS. You saved my TC-D5m. The belt repair worked. This was my first electronics repair ever, so it was memorable. Thanks
@@devinbrines normally I would be sawing logs by now but I only work weekends. Long 10 hour shifts. This week however i am on holidays so time to do some content production because it is unlikely I will be going anywhere. Travel is stressful. Kicking around the shop and taking the Harley out for a spin is refreshing and relaxing.
Looks like the ground wire that came off @6:50 (the screw) and @7:12 (the wire) didn't get put back on, that you can see @10:56 right beside your left thumb and gets tucked under the input bracket @11:38 and you can see its still there @12:20 when you put the screws back in. It should have been reattached to the circuit board with the screw you put in @13:26. I might be wrong though....LOL (don't think so)
congratulations! You spotted an intentional error I placed in there to see if anyone would notice. There is another one, but I won't say what it is or where it in because I want someone to figure it out. Yes I know about the ground wire, I saw it when I had the bottom board out, and you can see it too right next to the microphone jack. It was corrected. I also didn't show the spring that fell off and had to be put back on. I do have the re-do on tape, but my adult kids were having a battle outside my door and swearing at each other so I cut those scenes completely.
Yup go watch it again and tell me what you see. It is pretty obvious if you look closely. It only appears in 1 shot, and the next shot it is fixed. Just like this missed ground, but I don't have a shot in the video of the ground wire on the screw because I cut that shot due to the microphone picking up conversations in the next room that I didn't want going out (My adult kids were having a dispute with strong language) and because I wasn't talking I just cut that shot.) If the owner of this unit opens it when he gets it back, he will see that the ground wire is placed correctly.
These units were well laid out. designed for radio use, they were built like tanks. The 110B was a lower end mono device that used 4C batteries, DC bias recording and was a basic field recorder that was good enough for AM radio, considering that most of the recordings would be filed by telephone back to the studio anyway. The D5M on the other hand delivers results that are on par with most home decks. It operates from 2 D cell batteries, and uses a DC-DC converter to generate the higher voltages. It is a direct disk drive system that uses a servo motor, and the motor shaft presses directly to the rubber rim on the capstan flysheel which is supposed to lower wow and flutter, and when the rubber is in good shape it does. But as the rubber ages, the wow and flutter will increase. These were pretty much the standard for field cassette recording until DAT came along, and then Minidisk.
What's your point? Nothing can be done about that because the rubber tire that is on the flywheel is deteriorating and the part has not been available for 20 years.
@@12voltvids In the end you said that the player sounds good but it doesn't. I also own an old Sony TC-D5M but it has no wow and flutter whatsoever. I've read that wow and flutter issues with the Sony TC D5 can also be caused by a defective motor speed control IC (same as on the WM-D6C (I also own one of these)).
@@Turborider It sounds as good as it ever will. Speed control ic doesn't cause that. A bad motor can, but again no parts available and it is usually a flat spot on the rubber tire from years of if just sitting unused. I changed dozens of those flywheels back in the day. Even back then when the flywheel was available the part cost more than I got for the service. Most people that fix these want to spend the absolute minimum to get them going so they can auction them off on fleabay. I know if I was paying someone to fix something I was going to sell I would also do the absolute minimum so I could increase my profit margin when sold.
I have (3) Sony TCD-5's Pro II I write this guy but got no reply. Does anybody know a serviceman who can perform quality repairs on these? Lieberman Sound is no longer doing it. Please help if you know someone
Too much Wow and Flutter for that machine SPECS. And it is a direct capstain drive to reduce precisely that so I think there must be more to that mechanism that is not working right.
The rubber rim on the flywheel dries out after years of disuse and gets slippery. This generally works itself out after a few hours of play as the friction between the motor and flywheel rubs the oxidation off.
Oh. So that's it. It is the motor shaft that is slippering in the flywheel. Because you know that those machines are professional ones and have really good wow and flutter values and when you can ear all that flutter on a song played on that machine it is because something is not right off course. Thank you for your response and continue the good work you always do on your laboratory. Best regards.
Yes it is the same that the walkman DD and the professional recording walkmans used. Rubber dries out over time, but it will return to normal with some playback time.
The replacement belt is way too thick. That contribute to wow and flutter. Also all the rubber idler tyres and the flywheel rubber wheel needs replacing. But.. OUCH.. the way this guy pushes this machine around on his worktop - why so careless? I would never give you my d5M for repair. And cleaning the heads and pinch roller? Jeezus! Poor little D5M
Sony did that with all their tape recorders. Their reel to reel were called "Tape Corder" too. Probably to do with patents and trade marks. It carried through to "CamCorder" as well!
stupid idler-design, will never be the same once it's serviced/disturbed. So no, they were not built like tanks. You breathe on them too hard and the wires will break, etc, etc.....
You should be more carful with other people's equipment. At least put a towel down. Your to rough..... And not very careful......You probably broke the last one on the circut board. easy.
What makes you thing it is someone else's equipment. The majority of the stuff i work on is mine. Most is donated. I may or may not let you in on that fact.
That drive system is bit prone to misalignment. I have run into them before. If you disturb the motor mount the idler/flywheel and the motor shaft may not be at perfect right angles to one another, causing flutter as the motor crabs along the wheel edge.

I would have asked You to change all three belts in my my tape recorder knowing it would have been fine for the rest of my life.I would have payed the extra dollars. I'm in Europe so I rather do it myself. I have been through the same "oil changes" as You described were they changed the spark plugs and NOT the oil.I wish there were more people like You that fixes tape recorders to us people who still uses them. I just bought the three belts from a supplier in Germany with the original Sony part numbers. I will have them here in a week or so.I hope You're okay there. We see the riots that's going on in the US and the Covid-19 situation also. Have it well 12voltvids!
@12voltvids I just purchased a Sony TC-D5M and it is having the exact same issue - is there any chance I can mail you my device and pay you for repair? I can’t find your email or contact.
Great! thank you very much for posting this. Mine has stopped erasing all of a sudden. Do you know what it is and how to repair it? i actually have the TC-D5 PRO !!, doe sit make any difference when changing belts or repairing the erase thing? It also makes a noise sometimes on the left channel, especially when playing, and it s a very annoying noise that makes the arrow go crazy. Could that be repaired too? thank you very much in advance for your reply.
Clean the record play switch.
@@12voltvids Thank you very much for your reply, i guess thats for the left channel noise right?-
@@12voltvids You have any idea why it doesnt erase when recording? it records and leaves the previous recording too
@@markusziman363 check the wire going to erase head. They do break from time to time as they bend every time you press play. Scope the head and see if there is a bias signal. If no bias then either the wire is damaged or bias oscilator is broken.
@@12voltvids Thank you very much for your reply!
Smashing :-D
it sounds like the rec/play head still produces hf audio nicely :-D.
They put a lot of work in to that unit, mostly metal mechanism, that would not have been cheap in it's era for sure.
Love the meters, really classic design.

Dam shame you are alergic to cat dander, if you love stroking them i think there are alergy tablets that can lessen the effect, or you could have a proxy eg your wife do the petting lol :-D.
I have one of these, they are great cassette decks, amazing performance if it is in good shape, the wow and flutter seemed waay off on the video tho, mine has 0.06% like when it was new, that poor thing must have spent waay to much time without use.
Yes but it will come back with use. First it is rather cold in the shop this time of year, but once it has warmed up a bit, and run for awhile it should settle down nicely.
@@12voltvids True. Mine made a sort of grinding noise at first but after some use it quieted down nicely. Further cleaning of wheels and tires could't have hurt. I can't remember when I last used it. It could have been 20 years ago. Bought in '82 or so, the thing is a jewel.
Hi, what substance would you use to clean the volume pot? Thanks =)
Deoxit D5 is one of the best cleaners. Deoxit F5 is specifically designed for pots. It's expensive stuff but works.
@@12voltvids Cheers to the late night lifestyle (if you're American). Would you go D5 or F5? Sounds like either?
PS. You saved my TC-D5m. The belt repair worked. This was my first electronics repair ever, so it was memorable. Thanks
@@devinbrines normally I would be sawing logs by now but I only work weekends. Long 10 hour shifts. This week however i am on holidays so time to do some content production because it is unlikely I will be going anywhere. Travel is stressful. Kicking around the shop and taking the Harley out for a spin is refreshing and relaxing.
@@12voltvids A lot of people are talking using D5 and then F5. Would you use one or the other, or both?
@@devinbrines i only use d5 myself. That and Nutrol
Looks like the ground wire that came off @6:50 (the screw) and @7:12 (the wire) didn't get put back on, that you can see @10:56 right beside your left thumb and gets tucked under the input bracket @11:38 and you can see its still there @12:20 when you put the screws back in. It should have been reattached to the circuit board with the screw you put in @13:26. I might be wrong though....LOL (don't think so)
congratulations! You spotted an intentional error I placed in there to see if anyone would notice. There is another one, but I won't say what it is or where it in because I want someone to figure it out.
Yes I know about the ground wire, I saw it when I had the bottom board out, and you can see it too right next to the microphone jack. It was corrected. I also didn't show the spring that fell off and had to be put back on.
I do have the re-do on tape, but my adult kids were having a battle outside my door and swearing at each other so I cut those scenes completely.
did I win something?....LOL Now I need to watch it again....LOL Great repair!!
Yup go watch it again and tell me what you see. It is pretty obvious if you look closely. It only appears in 1 shot, and the next shot it is fixed.
Just like this missed ground, but I don't have a shot in the video of the ground wire on the screw because I cut that shot due to the microphone picking up conversations in the next room that I didn't want going out (My adult kids were having a dispute with strong language) and because I wasn't talking I just cut that shot.)
If the owner of this unit opens it when he gets it back, he will see that the ground wire is placed correctly.
Back when I was in radio. We used the Sony 110Bs. Could almost repair them in my sleep. Good units though.
These units were well laid out. designed for radio use, they were built like tanks. The 110B was a lower end mono device that used 4C batteries, DC bias recording and was a basic field recorder that was good enough for AM radio, considering that most of the recordings would be filed by telephone back to the studio anyway.
The D5M on the other hand delivers results that are on par with most home decks. It operates from 2 D cell batteries, and uses a DC-DC converter to generate the higher voltages. It is a direct disk drive system that uses a servo motor, and the motor shaft presses directly to the rubber rim on the capstan flysheel which is supposed to lower wow and flutter, and when the rubber is in good shape it does. But as the rubber ages, the wow and flutter will increase.
These were pretty much the standard for field cassette recording until DAT came along, and then Minidisk.
Name of song? 32:47
Beautiful little deck, but fiddely to work on.
They are very compact with jam pack circuit boards and moving parts - high end.
How did you not notice the ammount of wow and flutter when you were testing it?
What's your point? Nothing can be done about that because the rubber tire that is on the flywheel is deteriorating and the part has not been available for 20 years.
@@12voltvids In the end you said that the player sounds good but it doesn't. I also own an old Sony TC-D5M but it has no wow and flutter whatsoever. I've read that wow and flutter issues with the Sony TC D5 can also be caused by a defective motor speed control IC (same as on the WM-D6C (I also own one of these)).
@@Turborider
It sounds as good as it ever will. Speed control ic doesn't cause that. A bad motor can, but again no parts available and it is usually a flat spot on the rubber tire from years of if just sitting unused. I changed dozens of those flywheels back in the day. Even back then when the flywheel was available the part cost more than I got for the service. Most people that fix these want to spend the absolute minimum to get them going so they can auction them off on fleabay. I know if I was paying someone to fix something I was going to sell I would also do the absolute minimum so I could increase my profit margin when sold.
Does the TC-D5 really use the same motor speed control IC as the WM-D6?
I have (3) Sony TCD-5's Pro II I write this guy but got no reply. Does anybody know a serviceman who can perform quality repairs on these? Lieberman Sound is no longer doing it. Please help if you know someone
Good job !,
Could I get you to consider taking a shot at mine?
Too much Wow and Flutter for that machine SPECS. And it is a direct capstain drive to reduce precisely that so I think there must be more to that mechanism that is not working right.
The rubber rim on the flywheel dries out after years of disuse and gets slippery. This generally works itself out after a few hours of play as the friction between the motor and flywheel rubs the oxidation off.
Oh. So that's it. It is the motor shaft that is slippering in the flywheel. Because you know that those machines are professional ones and have really good wow and flutter values and when you can ear all that flutter on a song played on that machine it is because something is not right off course. Thank you for your response and continue the good work you always do on your laboratory. Best regards.
Yes it is the same that the walkman DD and the professional recording walkmans used. Rubber dries out over time, but it will return to normal with some playback time.
Or the new belt is too tight and cause additional slipping of flywheel?
And why you used 440Hz instead of usual 3150Hz tone for speed test?
Felix2417425 Concert A for most songs is 440Hz, so it makes sense why 440 is used by Dave for pitch checking equipment.
Where's the protection on your bench?
Protection?
@@12voltvids Looks a bit rough, worried about damage to this little gem of a cassette deck.
@@phillgriffith Bench is actually very smooth, soft wood. Nothing sharp to scratch anything.
Patience is a virtue.lol
The replacement belt is way too thick. That contribute to wow and flutter. Also all the rubber idler tyres and the flywheel rubber wheel needs replacing. But.. OUCH.. the way this guy pushes this machine around on his worktop - why so careless? I would never give you my d5M for repair. And cleaning the heads and pinch roller? Jeezus! Poor little D5M
anh cho em hỏi adapter cho d5m anh dùng là loại bao nhiêu ampe ạ?
indeed I was stuned !!!
It was already hammered! But he got it going for few dollars!
It's called a "Sony Stereo Cassette-Corder" Weird!! @1:42
Sony did that with all their tape recorders.
Their reel to reel were called "Tape Corder" too. Probably to do with patents and trade marks. It carried through to "CamCorder" as well!
Interesting!
Hello Sir. Is it possible for you to repair my recorder?
Well that depends on the problem. Parts are very hard to come by these days. These ones are a real pain in the ass to work on.
Certainly enough screws in that little deck!
I have two tcd5 for sale...
i'd like to know if anyone out there would be interested in my unit which is in need of repair. i can't afford to put any money into it.
Whats the model? and how much?
I have six of these, five working & a donor. my donor deck is in better shape than that one!
stupid idler-design, will never be the same once it's serviced/disturbed. So no, they were not built like tanks. You breathe on them too hard and the wires will break, etc, etc.....
You should be more carful with other people's equipment. At least put a towel down. Your to rough..... And not very careful......You probably broke the last one on the circut board. easy.
What makes you thing it is someone else's equipment. The majority of the stuff i work on is mine. Most is donated. I may or may not let you in on that fact.
