Question about Adcom GFA-5802 2-Channel Amplifier
Adcom GFA 5500 'mechanical' hum from amp. Comes and goes. 60Hz, does not affect sound from speakers. Thought it might be the transformer but toroids have nothing to rattle. Capacitors?
When power transformer is stres it gave that hum . check if you have some big power consume even with no loud. if yes might be capacitor. but my opinion that is not the transformer is the problem it need a bath with enamel

Possibly. Most amps filter out line hum via low-pass filters. If you can locate a schematic, those would be the caps to check.
