So what's wrong with the cheater plugs? Parasound amps were noted for having to use cheaters to avoid the hum. A GFCI isn't going to change anything. Gound wire and neutral wire are tied together in the panel anyway, technically.
Electrician's advice wanted: safely lifting ground
Hi all,
I've got a ground loop in my system between the preamp and multiple amps. The cheater plug experiment on the amp power cords not only solves the hum but also lowers the noise floor a bit more. So I would like to do this correctly in a safer, more permanent way.
Bringing all of the power cords in the system to one socket helped also but isn't as quiet as with the grounds lifted.
Can I change the circuit breaker to a GFIC and then tie ground to neutral at the wall socket so that there are no adapters involved? If this isn't the way to go please advise on what is. Even if I don't do this myself I'd like to know so that I can talk with an electrician.
Thanks
