There are a few things that might work, first off check the nuts and bolts connecting the power supply to the chassis as I had a bit of hum in an amp and by tightening the nut just a tiny bit did away with the hum completely as I think over time they work there way loose. One other thing as mentioned above is the Humbuster. If the hum is in the component and not coming through the speakers it's most likely dc on the line.
My tube amp power supply is buzzing away Help
My tube amp - Mcalister Audio has an outboard power supply that buzzes quite loud. Not through the speakers, but the unit itself makes a buzzing noise I can hear 15 feet back - very obvious.
I have read there is some material you can buy to place under the transformer to help. The transformer does not seem well mounted - kind of lose. Can anyone tell me the name of the anti-vibration stuff and where to buy it. I think I am going to tweak it before calling the manu to replace.
Thanks,
Bill
