A-S just replaced the transformer in my power supply with their usual responsiveness and efficiency. But it still hums! Ralph is away on a rare vacation, I am told, so my question is: Can the PS hum be induced by something in my main MP-1 preamp, such as a bad output tube? Apparently there was no hum when Bill tested it, so presumably it is in my system.
