Try running a wire( any kind) from amp to the screw of the wall plug faceplate
Question about hum from speakers
I know there's at least one amp engineer here... I'd like some help. I bought a used solid-state amp from ebay; the ad read "
McCORMACK POWER DRIVE DNA-.5 Deluxe REV B POWER AMPLIFIER - EXCELLENT CONDITION!"
Well, I swapped it in, replacing a Dynaco Stereo 120, and there's a hum from both speakers. I have to believe that the seller was well aware of the hum. What I'm wondering is, is the hum a result of some electronic component(s) in the amp failing (or having failed), such that it's salvageable by replacing the bad component(s)? Or would that be hoping too much?
