@MICHAEL MURRAY The symptom you are describing is typical of a servo IC failure. The other thing to be checked is the FG amplifier (on the left of...
Strage phenomenon with the capstan swap. Do both have new rubber ring on them ? About the crackling, I would clean the playback/record switch...
Hello Michel and welcome to the forum ! It's always a good idea to do research before buying vintage equipement, as there is a lot of speculation...
Here I have another example of a WM-2 (seems there are a lot of these for sale), this time the ad reflecting an honest seller and a really low...
About the washers, I think the third one wasn't fitted there in the first place. All units I have repaired only had 2 washers. I believe the...
Another aspect that I want to add is you need to align the motor so it's perpendicular to the flywheel. It has some play in the mounting bracket...
I would check the motor itself: does it have any lateral play when you try to tilt the rotor ? Some up and down play is normal, but it shouldn't...
It is clear to me that there is no obvious correlation between good gear and a specific serial number range. I attach a picture with the other...
Idler tire is different than capstan tire. But even the idler tire (the play one) is T-shaped, so not a standard one. I did search on ebay with...

That is interesting. From the diagrams, it seems that the "thick" gear version does not have a metal ring at all. It's a big gear that extends all...
The video in the first link is the absolute reference for these small DAT walkmans. The guy who made the video worked at SONY and knows every...
@kmare What I see in your pictures is different from both what is stated in the first post and the one that I repaired. Differences that I spot:...
This is what I am reffering to: Dremel Heavy Duty Cut-Off Wheel #420 - YouTube
There are a couple of methods that can be used to remove that screw: 1. Grip it firmly with a pair of pliers and rotate it. Depending on how bad...
It's interesting... I wonder if SONY really made 800.000 or more WM-2 or the serial numbers are not in order. This seems to be a very high serial...
Will do that. There is more to be seen, the IR sensor will likely need a new LED part. Dolby levels adjusted, mech lubrication.
