You are correct, there is no screw to remove on the back of the 350. I ended up just going to Radio shack and getting a ground isolator RCA cable. I hooked that up to my subwoofer. I am now happy to say that I am hum free. Thanks to all who replied.
how do you hook the radio shack rca cable up? what do you plug it into?

Jonah, apparently there were two sources here for the ground loop hum; the more significant one came in through the cable TV connection and was eliminated with the Axiom cable TV isolator. Another was coming in by way of the subwoofer power cord and this probably was the RadioShack item used to stop that. One of the cables would be plugged into the low-level sub input(or the receiver sub out, if more convenient)and the other side of the same color cable would be connected to the regular sub cable with a RCA coupler.

Enjoy the music, not the equipment.

I'm curious how this Radio Shack isolator works. Is it a 60 Hz notch filter? If so, that can't be great for bass.

Hi blondespot11,

You can get rid of it easily with one of these Axiom ground isolating transformers:

Thanks! This took care of my hum. It was annoying me and decided to google it the other day!
