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.

Greg, a "cheater plug" is an adaptor(about $1) that can be used for plugging a grounded three prong plug into two prongs of an outlet, defeating the grounding and possibly eliminating a ground loop(but also possibly creating an electrocution problem if a short would occur in the receiver). I've gotten a bit dizzy following the experiments, but if the only thing plugged in is the receiver and you don't have any cables except the speaker cables(not the sub)connected to it, play an FM program. No ground loop is possible in that setup, so if you still get the noise, it's the receiver.

Enjoy the music, not the equipment.

I just put the receiver on FM, but with no antennae hooked up, and I still get hum. I'll try to buy an AVR335 locally for as close to internet price as I can. Thanks for the help.

It had to be the receiver as my new HK AVR240 does not have that problem.
