sorry edjosh23, I'm not very good a diagnosing without actually seeing and touching.
Have you tried this amp in a different power outlet or even in a completely different location. I'm wondering if it is a issue with your house power supply. Have you other amps that are OK?
Are your RCA sockets, LM3875 etc completely isolated from the case?
