Forgot to say that I do have Directv and audio is connected to the preamp via RCA jacks. So maybe a RCA ground isolation device is what I really need.
Isolation Transformer - Use with Cheater Plug
If you plug equipment into a isolation transformer like a Tripp-lite using cheater plugs, do you still get the shock benefit? I am thinking you are because the transformer is still plugged in the correct, grounded way. But technical knowledge has never been one of my strengths.
(The only way I can prevent loud hum is by using cheater plugs on both my preamp and amp. Plugging them into the Tripp-lite without the cheater plugs did not work.)
