Hi all, I recently started fixing up a wm-10 I bought off the bay. It’s gone well on the mechanical side of things: - the usual belt replacement - an issue with the buttons engaging - repositioning of the autostop spring in the head assembly Now I need to tackle two issues: 1) 1-2 second whine through headphones after stopping playback (assume this shouldn’t happen) 2) background buzzing (mild but noticeable) during playback Not sure if this is related but the fly wheels take about 1-2 seconds to stop. Could be that a lot of Walkmans do this and I’ve just never noticed...? Pretty sure the audio issues are capacitors that need replacing, but I was hoping someone who has experience with the wm-10/20’s could give some guidance. Any help is most welcome!
