Hi all. I recently decided to restore my WM-D6C. I bought a complete set of rubbers and belts with 'Fix Your Audio', it was a bit difficult for the first time, but finally I succeeded. Likewise, I also changed the mute module, which I bought with deb64, since the Walkman emits a 'pop' at startup. I was very proud of myself to have succeeded alone in the restoration of the Walkman! Everything worked perfectly for two weeks and suddenly during the playback of a cassette the sound began to change as here the speed was no longer regulated causing a sound like seasickness and tremolo. I tried to look at where the problem was, but I couldn't find the source of the problem. So when I start the Walkman everything works but after a few minutes the speed is affected causing a kind of tremolo, seasickness. Any idea ? Thank you.
