Hello, my WM 31 works fine except that the servo changes its speed or stops when I move it (or the walkman) I guess the problem comes pbly from the flat ribbon cable from servo to pcb which is broken (video here wetransfer link https://we.tl/t-xucxqlsd7g ) . Not sure. But as the servo is mounted on silent blocks it can move and create miscontact in the ribbon after years.. This is my theory. What do you think? Any idea ? Hope I m wrong and it can be cure easily Thank you
I finally repaired the contacts between motor and pcb by adding electric wire See images It works fine now ...
