@Mister X Nice post - thanks, I always learn something new here. Homer L. Davidson, the author of that article, wrote an excellent book called...
Thanks, @Valentin—really appreciate the context and insight here. It's interesting comparing this to my Sony WM-GX670 (which you helped me fix a...
Hi Norm, Thanks for the note! It’s reassuring to know I’m not the only one who couldn't track down official W&F specs. I’ve restored a few 1983...
Thanks, Norm! That 0.3% WRMS gives me a much more realistic target to aim for—I had a feeling getting anywhere near 0.1% RMS on the WM-2 was...
I hope so too. Chances that it wasn’t butchered are in your favor since wm-2s in the Sates are not as wanted as D or DD series, so people just...
This makes it more challenging. These gen1-2 etc , iterations really complicate things. Unfortunately, my two WM-2s are gen 2, so I can’t help
@worldwide137 Norm, I am curious what W&F readings you are getting after your restoration? Did replacing the servo caps help lower it at all?...
Norm, This could be item #4. Maybe the Gen 2 has a different "paper shield," and it looks like this (below). There is a black grounding wire...
@worldwide137 Norm, thanks for pointing that out—there is a red Teflon washer seated between the center gear hub and the magnetic driving gear....
Thanks, @Valentin . I went ahead and desoldered the motor to test it completely free of the circuit. Without any load, it draws a steady...
@Mister X Thank you for posting this link. This guy is simply amazing... Is there something he can't do?
@Valentin, I did some current draw testing, and the results are interesting. The Service Manual (SM) specifies: Play Mode: 115 mA , FF / REW Mode:...
@Valentin , thank you once again. I appreciate your expertise. I reassembled it yesterday, and all that work made no difference whatsoever. I...
@Valentin Thanks for the reference to the thread. I appreciate it. I have read it earlier. The whole thing befuddles me. I can’t see any visible...
I received the proper 44mm belt and a new pinch roller from Marian (as always, top-notch quality). The new belt definitely improved playback...
Here's an article from 1983 [ATTACH] [ATTACH] [ATTACH] [ATTACH] [ATTACH] [ATTACH]
@Elite-ist Nando, I’ve installed pinch rollers from Marian on my Sony TC-K679ES and AKAI GXC-760D, and his products are always of excellent...
Update: After a day of unsuccessful tinkering with the usual suspects, my W&F was still sitting stubbornly high at 0.67% RMS. I finally decided to...
Hello Walkman Wizards, I recently picked up a Sony WM-2 to recreate a childhood memory. It needed service, so I dove in completely. I followed...
This is a very interesting thread. @Valentin, thanks for sharing your expertise here—this is supremely helpful! I recently picked up a WM-2...
