Hi there - I'm working on a Sony WM-F606 and have reached the limit of my expertise I've done the mechanical work and all functions seem to operate But I struggle with the electrical stuff > Can the experts spare me a minute to listen to the attached audio (with a tape in) and advise. The audio is one channel just because of the way I recorded it. You can hear the effect of switching the Dolby and the tape select during the clip.. Recap? thanks for your time WM-F606.mp3
1. Check grounding to the main PCB. Clean FWD/REV switch. 2. This model (170 derivative) is known to have capacitor problems. Try recapping. Good luck!
