happy new year everyone

im still buzzed from yesterday but I'm trying to fix an amp i just purchased for dirt cheap .the amp make and model is Autotek MM2000.1d that i purchased in a lot of blown amps from local installer .the unit powers on and idles fine and getting good power to the op amps but no audio out.I hear the relays click on power on but very faint .
When i turn the gain up
-with no audio signal connected everything looks good
-with audio signal connected and the gain turned up 1/4 way the relays buzzes to the beat

any thoughts ?
