Ground loops caused hum with my regenerator. I only had pre amp level devices plugged into it. (P-300) I lifted its grounds first which solved the hum issue then ended up lifting the two power amp grounds not plugged into it which resulted in more sound improvement although the hum was gone after lifting the regenerator ground.

People smarter than me have said safety grounds can act like a noise antenna and I agree. No safety lectures please.
