Sony walkman wm-4: Sound Checks on Walkman WM-4

Fri, 22 Nov 2024 12:10:38 -0700

I've got myself a WM-4 from ebay, in more or less alright nick. Opening it up to check an issue with it's potentiometer a belt snapped. I've now replaced both belts with new ones, and had a quick look at the potentiometer problem.

I am now stuck on a sound quality issue along with the volume meter problem. I only listened to it for half a song before the belt snapped initially, so I don't know if it's my tinkering or a consequence of the Potentiometer. I've cleaned the head, pinch wheel and capstan system, but not demagnetized yet, though I doubt this is the issue.

The potentiometer is spinning round and round instead of the set limit it's supposed to have, and clicks on or off jumping to random volumes and channels. What is it's part number? does any one have the Manual for the WM-4? Would it be worth finding and using contact cleaner on it?

I would love any advice you have. Regards

Sony walkman wm-4: Intermittent starting & slow playback question

Mon, 27 Nov 2023 00:51:22 -0700

Hi all.

Recently acquired a silver Sony Walkman WM-4. Installed new batteries, new belts and lubed gears. When pushing play sometimes it it will start and sometimes not. With the back off I can rotate the silver metal gear by hand and it will eventually begin to work. When it does come on the sound through the headphones sounds like your underwater. I can't seem to find any information showing where to adjust the speed on this model.

Thanks for any help or advice

Sony walkman wm-4: Spring popped off after tear-down

Sat, 12 Sep 2020 07:58:11 -0700

Hello!

currently my cassette player plays cassettes, but the eject function no longer works. A spring popped off, and I'm not sure where it goes. The door for the player no longer opens when the eject button is pressed.

Since the eject button no longer works, I cannot put a cassette in without having to press down a plastic piece that is stuck in the down position.

Any help would be greatly appreciated, its mostly a mechanical problem.

Thanks!

Sony walkman wm-4: Tape won't spin. Please help!

Wed, 08 Mar 2023 21:19:17 -0700

I purchased this Walkman off of eBay recently, and in the description it claimed that the Walkman wouldn't work with batteries, but instead would work while plugged in. When I received it, I tried batteries and the indicator light turned on and it sounds like the belt is spinning inside of it but the tape that I'm using (good condition) isn't playing. I noticed the little nubs inside of it aren't rotating. The belt itself is something I looked at and it looks a tiny bit stretched so I ordered some new ones and they arrive tomorrow, but I was curious if it isn't the belt at all and instead is another problem. Can anyone help? This is my first time doing this sort of thing and I was super excited about trying a Walkman out for the first time.

Sony walkman wm-4: Sony Walkman wheels not spinning

Thu, 28 Nov 2019 10:53:16 -0700

Hey everyone!

I have a problem with a mid-80s sony walkman (Sony WM-31), as the wheels don’t spin when I press play. The belts seem fine and the cylinders spin when I manually move the cylinders the belts are attached to. What’s the problem here? Could it still be the belts, i.e. they’re too loose maybe?
