Just picked up a Harman Kardon HK330A and a Sherwood S-7200 from Goodwill in pretty good shape. Both sound very good when the input is solid. But...
Both of these units have a decreased FM audio level and the Sherwood also loses the right channel when switched to FM input. Other inputs are louder and (on the Sherwood) in full stereo.
AM and Aux Input (cd player) seem to work very well (stereo and mono). Same results also when listening through headphones...
Question is: would a simple recap of the FM board (or multiplex) possibly fix this problem? I certainly don't want to inadvertently cause harm. Already went after knobs and selectors, but will also be going after switches with de-oxit...
Thanks for looking!
