Yes, they are. All plugged into the same power strip. I've got a new strip on the way and will use a GFCI tester tonight to make sure there isn't something wrong with it. But besides that I don't know what to do.

Have you tried a different circuit within the house? You might have a ground connection on that circuit but it could be weak depending on how the house is grounded?

I will try that now. This only happens with one particular PC that I use for music. But lifting the ground on that PC doesn't make a difference. Only the ground on the SEX amp does. Could there be an issue with the wiring of the SEX? How could I determine that?

Just tried a different breaker. Same noise.

Same noise is audible through Stereomour and speakers, too, just much quieter.

Since this isn't a problem restricted to the SEX I'm going to start a different thread in the general forum.

So what are my options for removing the ground loop?

I'm just mirroring what PJ posted in the other thread you started on this same topic.
