I have a really cool Sharp WQ-T222 boombox with a super unique mechanism. I managed to fix the initial issue it had where a plastic piece atop a spring came loose but as soon as that was fixed the motor stopped running.

I traced it back to the switch pictured. I cleaned it with iso soaked paper till nothing came off but it's still super finicky and only works about a fourth of the time.

What are my options? I would love to get this thing working again. Is there something else I can do to make the switch work or should I replace the switch, and if replacing is needed, what is the specific name of the component/where would I start looking for a replacement?

I don't know if anyone else is interested, but IDK I thought the way they did the dual tape deck is so friggin neat. I haven't seen anything else like it yet. Figured maybe one or two other nerds would also appreciate seeing it before I finish cleaning it up, getting it running, and closing it back up again.

I usually sell the ones I fix because I like getting them off to other people to enjoy but I am genuinely tempted to keep this one for myself just because it's so unique, you know?

I got a walkman that ran fast. Opened it up and the speed pot had literally fallen apart. See pics for potentiometer dimensions based on my calipers.

Got a second one to try to snitch the part and it has the same issue.

How exact do the measurements of the new pots need to be? I was looking at these ones but any advice on confirming fit before I buy would be appreciated:

I'm fixing a work friend's DS; the hinge broke along with the ribbon cable and this other cord. They ordered a new shell and replacement ribbon cable and I could pull a spare wire out of my stash but I was wondering, before I go to the trouble, is it still used?

I know they can't onnect to modern networks but I'm not sure if it's also used to let them talk to each other directly or whether there are other things you can still do that rely on the antenna.

Trying to wrap my head around calibration. This service manual mentioned a V.T.V.M. which google says is a vacuum tube voltmeter. Looks like it wants me to output the voltimeter readings to the scope but I don't have a meter that has that sort of output.

What's the workaround here?

edit: damm typo. Won't let me edit the title

I was dumb. The front of the boombox fell forward, dragging rhe connector with it. The connector snapped off.

Is there a way to salvage this? Maybe soldering tiny wires between the connector contacts and the contacts on the board? Are there any steps I should take to secure/reinforce it if I do that or is there a better option?

NOTE: the last couple connectors weren't used. There's nothing there and I don't see any wires sticking out of the unused pristine soldering pads for them like I see for the other contacts.

Context: I'm trying to repair a couple boomboxes but a couple of them have broken pieces. The first one has a little black catch and the second one has some more obvious bits. Trouble is different types require different glues.

Note that the black crap on the second one was from some plastic molding kit someone recommended but it doesn't stay malleable long enough and it also doesn't do a good enough job affixing the two sides of the break back together so I abandoned that endeavor.

I've tried looking online and on Reddit but I can't find any details listed; what type of plastic is this? Also any information on commonly used plastic types in boomboxes in general would be amazing since I would love to learn more and do a better job of understanding the materials used and how to best work with them.

Got an old boombox with a couple buttons that have seen better days. It sounds like plastic glue is the pro move here but I was wondering, what kind? It sounds like I will want to choose based on the plastic but I don't have any experience identifying various plastic types.

Any assistance would be amazing!

I'm super new to speakers and can't find info on them.

update: grabbed the pair and their covers!

Edit: Love how everyone is like "yes!" until after I get them, LMFAO. Ah well, I'll make the best of it.

I saw them on AliExpress and Ebay and I was curious but I can't find any information on them.

Are they pointless novelty junk or are they actually useful, and if useful, how are they used?
