As soon as I turn the power "on", I get 60HZ hum. With volume pot 100% off. It starts with all tubes being cool, and stays there during operation. The hum level is low, so it is not heard during receiving the station. Otherwise the set operates flawlessly. Does not respond to the volume level change. Before I start digging deep, I thought there may be some obvious remedy simple for everyone but me. The set has been completely redone electronically, with all capacitors replaced.Thanks.
