- Hi all, I hope you enjoy this video. I had no end of issues with this lovely player, but I'm happy with the end result. I also used the following webpage which gave me some useful pointers, so a big thanks to Peter Vis!

Thanks for this. It took me back when I was a wee lad and got my first walkman. This was the exact same one. The sound quality was outstanding.
It's a pleasure to see like that Walkman from the good old days. You did a good job. Cheer.
шикарная работа! автор молодец! купил точно такой же плеер. внешнее состояние просто супер, но внутри нет двигателя и провода все оборваны. буду пытаться восстановить.
Excellent work
Thank you!
I have m3330 , Nice machine !
My advice on the soldering would be to use flux and desoldering braid to remove the old solder on those wire connections, then flow new solder and attach wires. Looks like you just soldered on 40 year old stuff which will give you dry joints and unreliable connections. Also wonder if those electrolytic capacitors are gonna be out of whack after 40 years. Otherwise good job.
Yep you're right, I use flux all the time now and also desoldering braid, the flux in particular makes a massive difference! I think you're right about the capacitors, I might have a go at replacing them down the line...
Hi great vid .. I’ve watched it a few times now … I have exactly the same model but my play button presses fine but doesn’t seem to work inside the deck … does that sound like a belt too? Thanks
..der Hammer....danke für den beitrag....
My father had one with the same color and the same volume scroll problem
wow great
Do you by chance have the link to the belt seller on ebay? I'm looking to fix an old player i found on ebay
i have 2 m4430,s in white one is perfect other needs belts and has audio problems only 1 channel and it is distorted i did find a dry joint on the headphone jack but that done nothing ,i think either the amp chips have failed or preamp is faulty but today a denon tape deck failed dodgy panasonc tape mech and a gear stripped teeth so i broke it up for parts looking at the main board there was an la 3161 ic a google search and it is pin compatible with the 3160 in the sanyo so desoldering it now .
What size belts does it use. I’ve just ordered on in eBay. They say it’s it all good but for future reference I’d like to know.
Did you find out? I'm thinking of buying and fixing a used one and I'm searching for some belts
@@cptbtrface3301 no clue mate sry
I have same ,but I don't know why it's not turning on and strat to heat the battery !
👍👍👍
Excuse me sir, I want to ask what is the size of the rubber for this walkman?
17 cm 1.5 mm or 18 cm 1.5 mm?
This is wm-8 red
Why you don't buy some set of professional screwdrivers? It can avoid stripping the screw's head when there is some hardened thread locker like in old Japanese electronic. By the way, I had one of these back in day, a bulky machine but with a nice sound and fairly cheap compared to the very expensive Sony Walkman! Unfortunately someone stole my unit, that was identical to this one. May be it's the same unit.. ;)
Thanks for the advice, I agree my screwdrivers are pretty bad. I have 3 of these same units (This one, 1 partially working, 1 donor) so one of them could be yours :)
Thank you 🎵
I have the exact same model. I put new batteries in it today. Nothing, no movement at all. The red power led didn't light up either. I'd love to get it going again. It's in good condition for forty odd years old. Might try and source a 6v supply. Have any suggestions?
Is there corrosion on the battery terminals? I'd recommend a trying with an adaptor as you've suggested as well. You may just have a loose wire...
@@monkeysyndicate I'm going to picked up an adapter and take it from there. I cleaned the battery terminals. Hopefully it just a loose wire in the battery compartment. 👍
@@stevocarton It worked? I also have the same issue but I think my case will need new caps :(
@@carlosestebanvr it was the battery contacts. I folded up some tin foil and put it in between the batteries and the contacts and it worked.
@@stevocartonis this a permanent fix?
Have one still new in the box :-)
Wow! I'm jealous!
Don't play any cassettes in there before changing the belt and lubing up the gears a little. Even if its only sitting in a box, the belt's could be loose, which will cause tapes to be chewed on by the machine, or it doesn't spin the gears at all.
@@farhandoniepratama5813 I do not plan to unbox it ever! :-)
@@1walkgirl What a waste. Enjoy your real life NFT.
Pois use!!!!!!!!!!😁😊😁😊😁😚
does this have autostop feature?
No
Do you use JIS screw drivers?
No, just a small Phillips one which worked ok, the screws took some convincing though. I Guess I was the first person in there since factory assembly!

Do you get paid for fixing
Hey no, it's just something I do in my spare time. I find it interesting to tinker with old tech!
