Axiom Home Page Forums General Discussion Technical Questions Is this a ground loop hum?

I missed that one earlier. What is a cheater plug? If I go to CIrcuit CIty will they know?

Also, I tried the suggestion of running wire from a screw on the bottom of the receiver to the cold water pipe under the sink and the hum remained. I'll try the cheater plug and see if that helps but if not, I get a new receiver.
