I found this Ultronic SC-5 at Goodwill a while back and finally got around to testing it. It works, but it sounds like the tape is speeding up and slowing down randomly. Is this as simple as just figuring out how to open it up and replace the belt, or is there more to these little players then I am expecting? Never really tried to fix any cassette players, so any advice would be greatly appreciated.

So I found a Panasonic SL-H203 the other day for free, and replaced the belt. It worked, but spun to fast so I went to adjust the speed adjustments knobs inside and one immediately broke (both are very corroded). Seems like an easy enough replacement, but I can't find any information about what values they are. Anyone happen to have a service manual or know where I might be able to start? I don't see any markings on them or the board that are helpful.

A friend messaged me that he had found this sitting around from a while back that he had planned on reselling before learning I collect old Apple stuff. Very lightly used it seems, in the original box with a battery that still holds a charge, and all of the original disks and accessories. Very stoked about it.

Randomly popped into one of my local Goodwills to look for summer shirts, and found this Symphonic ST413B instead. powers on and shows snow so figured for $10 I’d grab it even if it’s RF only. Tomorrow begins the hunt for a cheap VCR to allow RCA inputs.

I would say a bit over priced as they were all $50, but there was also a Sears ultraportable for $25 over in the office section. I was happy to find a Facit TP1 elsewhere in the store, but had to restrain myself.

So I stumbled on this machine at Goodwill yesterday after passively hunting for a Laserdisc player for a while, and it seemed ok. It turned on, opened and closed, but wouldn't read. Did a quick Google and general consensus for any repairs seemed to be needing a new belt. The player wasn't too expensive, so I figured hey let's give it a go, I have a bunch of spare belts laying around.

Fast forward to today, I open the player to see if I can see what is happening when it tries to play something. Hit eject, hear a noise. Now I have a broken gear in the chain of open/eject gears. One of the gears came out, it looks like maybe the small ring that held it in place cracked so it didn't get held down anymore. The second one seems to be missing teeth, so I am assuming that need full replacing.

Any thoughts or ideas where to find these parts or what else to try? It's my first player, so it makes sense that it would end up being the biggest pain. Hopefully at the end of this though it will be working. If not you'll be seeing me again seeing if anyone needs parts!
