Hi Ant1vl, I've just repaired my WM-EM50 with a new belt, because the old one was falling into some black slime, but I have the same issue with the volume. Do you remember the caps you've ordered to repair yours? My player is in a really perfect shape. Nothing is worn out, the casing is also looking like new. Do you think its worth repairing that thing? I have zero skills in soldering. Br from Cologne! Henrik
