Sounds like ground loop hum. Try using a cheater plug to lift the ground on the three prong plug or use a device designed especially to eliminate ground loops. I'd try the plug first to see it that's the problem.
Humming sound from my speakers
When I turn on my power amp there is a loud humming sound from my speakers. Although the sound gets softer after about 3 seconds there is still an audible hum. I don't think it is my peramp although when I adjust the volume through the pre amp you can hear a crackling sound from the speakers
My power amp is Audio Research VT 100 (tubes)and my pre amp is LS 15 (tubes)
Any assistance would be appreciated.
Thanks
Daniel
