In Reply to: RE: Tube amplifier hum posted by Palustris on May 20, 2017 at 08:57:45
The tubes are not at fault, as I have tried others with the same hum, which btw, is through the phones, not in the amp itself.
The power supply cord is not grounded.
I am pretty sure that the other amp, on which the problem amp is sitting, is acting as a ground for the problem amp, as someone mentioned.
The tube amp is the ALO Pan Am, with the non-upgraded power supply.
Not being overly mechanically inclined, although I can use a soldering iron, is there anything I can do myself to alleviate the problem, or do I need to take it to a technician?
Thanks so much for your help.
