For a novice it is a risk of losing those small cut-washers when taking gears out, as they tend to fly out if you do not keep a finger over or put...
This is cool, I haven't seen one of these before. According to wikipedia, it uses helical scan like DAT and it appeared around 1992. Probably SONY...
@CDV While I agree not to trust a seller and be circumspect, putting all sellers in the same bin is something I do not agree with. "untested" -...
No, I did not repair any 555. But @Jorge certainly has, so he can answer your questions. Creating a separate thread regarding that question is not...
I recently bought a cheap SONY D-250 Discman on an auction site, which was described as faulty laser. Given @Jorge told me about the common...
I do agree with you, it's not just ebay. Some people will tell you anything in order to sell, that's perfectly true. But the point I was trying to...
The point I was trying to make is a little different: there is a category of people who want to buy these things for collection and want them to...

Above the right flywheel, it's a hole cut into the PCB designed specifically to align the switch with the mech.
It is an annoying problem, because a new redesigned gear is unfortunately not available. Given what you say, the old one was probably at the point...
It's the spring of the engaging lever. It seems it's catching in that post where the play button is supposed to go. I think one of the pins on...
This is one of my favourite walkmans out there. There is something that I like about full logic units with a separate motor for the logic control,...
Regarding the soldering, I recommend something like Hakko FX888D or Weller WE1010 (the Weller is much more common is Europe). That's about the...
The problem you are having is a broken clutch gear. Very common on these units, you will need a donor to fix the problem. More info on this...
