My system has developed 60hz hum. I have traced it back to my MC-1. Can I correct this with a power supply replacement?
The hum is present with no inputs connected to the MC-1; disconnect the interconnects to the power amps and hum is gone. Tried different interconnects but hum remains.
I have tried HUM X but hum remains
FYI Pyramid doesn’t sell parts; Mouser doesn’t have the power supplies
suggestions are appreciated
