Transformer Hum

I use a PS Audio Humbuster and this works well on my tube gear. It really quiets down those transformers.

Listen to Newbie, he has the right solution for you. If you have TV cable hooked up anywhere on your system, that is the first place to look.

Newbee may be correct, but his "solution" will not work in every case; in my personal experience I exhausted all the usual suspects (cable routing, cheater plugs, changing out tubes, swapping cables, both IC and power, even turning the amp around to see if positioning was the cause) and as a last ditch hopeful solution bought the PS unit. This did not remove the all the hum heard through the speakers, but a good part of it, but it certainly quieted the trannies tremendously.

Stevecham, What do you mean when you say Newbee's "solution" will not work in every case? I think you may have missed the penultimate paragraph. Isn't that exactly what you did to solve your problem (in part), install a line filter? :-) :-) Jeeze, a Newbee needs all the credit he can get, throw the dog a bone...............
