I just acquired a Sony WM-AF64 with a fully-functional radio but a broken tape deck. I replaced the belt with one supplied by a Slovakian dealer mihokm on eBay (type Sony WM-AF64 belt). Unlike the fat belt you used as a replacement, this belt is much thinner but a nearly-perfect replica of the original belt (which, on mine, turned to tar). This OEM-like belt does not flop around and transmit wow and flutter to the capstan (and, of course, to the tape) and has absolutely no chance of rubbing against the capacitors. Additionally, these belts are factory-fresh; no belts from this vendor are over two years old.

The AF-64's mechanism is definitely of better quality than that of the WM-F2085 (released in 1990), with many more metal parts. The WM-F2085's mechanism has all-plastic belt pulleys, with the only metal parts being the capstans and springs.

Capacitors may have leaked because the polarity for the connector is negative on the center, which is reverse of almost everything else using those connectors. I just found one cleaning out an old drawer. AM/FM works but the belt is probably broken.
@HardDiskLover 2 жыл бұрын
The polarity issue here isn't the cause and would only affect the capacitors on the power rail. The capacitors used here are known to leak regardless. A lot of devices manufactured during this time frame need a full recap, because they just start to leak due to the chemicals used and the way they are constructed. The sega game gear is another device that has an issue like this.

I'm at a loss here. So I swapped the capacitors (99%sure they're right), but right now I'm getting no sound (as I was before). Now, the ribbon cable leading to the radio I have unplugged (the radio didn't work before but I think I extra broke it. I think I shorted/over currented something in it when I plugged a cable from my computer usb port to the DC in...) because when it's plugged in the motor won't run when I press play (in tape mode). As for the headphone out, with the earphones plugged in, I tested the R, L, and G to the + side of the battery and they are all read just over 2V difference. Is this right? I thought the R and L would be different from the G. Can the jack be bad? I mean it's only 3 connections. Also I hear a tick in the earphones when testing the battery + to the L and R. Another weird thing is if its in radio mode and I plug a cable from the DC in to the usb port, it spins up the motor and I can hear the motor through the earphones. Any ideas?

have you made sure if the capacitors are soldered on with the correct polatity? also some could not be soldered on fully... there shouldn't really be any voltage on the audio output that high.. in a worst case scenario one of the ic's could be broken aswell...
@xxuncexx 8 жыл бұрын
HardDiskLover Yeah I made sure they were all correctly oriented and I pressed them down when I soldered them. I'm not sure if this problem existed before as the belt was broken and I couldn't use it.
@HardDiskLover 8 жыл бұрын
that doesn't soud too good :( do you have a scope? You could trace all voltages and signals to find the issue like a drop in voltage or so... it could also be that one of the Ic's or something else is broken or the leaked electrolyte has corroded the traces on the board. Getting replacements ic's is still possible but a bit expensive and fixing corrosion issues is very challenging...
@xxuncexx 8 жыл бұрын
HardDiskLover There's a variety of things I can think of. I don't think its corroded. Maybe an ic got fried. Maybe pushing down on the capacitors mashed the solder together and is creating a short. I could try re soldering but if that doesn't work then I'm not sure. I'd be nice to have a schematic so then I can trace it better. But I'm not too fond of how the headphone jack works so I'd also have trouble knowing the proper voltages to look for.

Your dad had good taste in this Sony WM AF64 player... it too was my 90's favorite too; riding my bike, touring our city daily, and listening to tapes and the radio - good times. Before that, in the 80's, I used a Sanyo M-G10 personal cassette player; played it all through my teen years until I lost it in storage - both good and bad times. I just bought a few used Sanyo's; a M-G30 and an M-G31 - both need some repairs. And I still have my old Sony WM AF64 too; but like yours, I too believe the belts are melted and one or two capacitors are toast. OK, I watched your video on the repair... forget it; I am sure I cannot do it... I removed both screws from the back, but it appears there are clips holding the back plate on tightly. My experience is, I always break a clip. So, how much would you charge me to repair m Sony WM AF64 Mega Bass?
@HardDiskLover 6 жыл бұрын
Sorry I can not really offer repairs. I assume you are in USA. I'm in Germany. The shipping cost alone would already be really high +80€ with tracking. I'd recomend you to get a set of spudgers and make sure that all screws that hold the back pannel on are removed. with a bit of patience and a spudger the back plate should come off without breaking any clips. At around 6:32 you can see where the clips are. Or you could ask at a local hackerspace if someone can help you out ;3

Hi, good advice; thanks. I watched your video closely and I believe I can do the job just as you did your; albeit, with some patience. Actually, I thought of buying a soldering kit & tools off of ebay and try the repair myself. It looks like the repair on the Sony WM AF64 is pretty straight forward, and an relatively easy repair - all the parts are on ebay. However, the Sanyo M-G30 & MG31 are a bit more tricky, and the parts seem to be a bit harder to find. Maybe you can do a Sanyo M-G10, M-G30 or M-G31 repair, I believe they were Sony's early 80's top rival from Japan and still worth collecting and repairing. I have both M-G30 and M-G31 now... both are very nice, but both have issue; one has a headphone static/cut-off issue, and both need new belts. Any helpful hints would be greatly appreciated. Again, thanks so much for the reply. Cheers from SoCal

The circuit board is held in with a few screws and clips. Its quite a bit of effort to remove so patience is needed. It only comes out of the case with the tape mechanism. if you have the whole assembly removed from the case then you can remove the PCB from the tame mechanism To clean up the rubber I use Isopropanol with some q-tips and paper towels. *Don't use something like acetone because that may dissolve the plastic wheels!*

Hi, ich hab gesehen dass Du aus Deutschland bist. Ich bräuchte Hilfe mit einem Sony Walkman WM-A602. Der Ton ist sehr leise und rauscht leicht. Beim Umschalten von "Dolby NR" bzw. "Tape CrO2 Metal" fängt es extrem an zu rauschen und der Ton geht ganz weg. Ich hab ihn mal aufgemacht und festgestellt dass einige Lötstellen, u.a. von den beiden eben genannten Schaltern nicht mehr gut ausgesehen haben. Leider haben ein paar Tropfen Lötzinn nicht geholfen. Das alte Lötzinn auf den Pads war wohl schon zu alt. Leider bin ich nicht so der Fein-Löter, dass ich auf dem engen Raum die Schalter ablöten und komplett neu anlöten könnte. Zudem weiß ich nicht, ob noch was anderes nicht mehr in Ordnung ist. Daher schreibe ich Dich an und wollte fragen, ob Du Dir das Teil mal vornehmen könntest. Viele Grüße.

Hello, I just found my dads old walkman (WM-F59/F69) and I just have some questions about the capacitors since they leak and I plan on changing them out (also I'm only somewhat familiar with electornics). I plan on ordering from here: www.mouser.com/Passive-Components/Capacitors/Aluminum-Electrolytic-Capacitors/Aluminum-Electrolytic-Capacitors-SMD/_/N-75hqx Are these the correct type of capacitors? I'm also noticing on the walkman that some capacitors bottleneck at the bottom while some don't. Can I replace them with all the same type (aluminum electrolytic)? Also I notice the capacitors are 3 different diameters and all the same height, what are the correct dimensions? Anything else I'm missing? Thank you for posting and for any help you may provide.

The stuff leaking out of them is electrolyte. I not exactly sure if it is dangerous, but you should watch out to not rub your eyes or for whatever reason stick your finger in your mouth while doing this repair, just so that nothing of that stuff gets inside or in contact with sensitive regions of your body. When you're done replacing or take a break wash your hands thoroughly with soap. And one last thing: if you have issues finding a capacitor with the same Voltage as the one you want to replace you can use one with a higher voltage with no problem. Only *don't* select one with a lower voltage. If you use a lower voltage one it could explode!
