RE: Odd hum issue - suggestions ??

Could be the unit is picking up AC hum from house wiring. Outlet grounded properly? Polarity of house wiring (Hot, Neutral) consistent?

Are the input wiring of the amp shielded? Grounded at input side, only?

Check all grounding points within the unit. Tight and clean. With least amount of potential between grounding points. Near zero resistance between points of grounding.

Good luck!
