Floating the Ground


My B&K Ref 30 is sick and not working quite right. I am awaiting the arrival of a new Ref 50 but they keep delaying the shipment.

One of the problems is a terrible hum in my speakers coming from the preamp. It doesn't matter if the ref 30 is on or off, if it is plugged into the power source (wall or conditioner) the hum immediately starts.

I think floating the ground on the Ref 30 would eliminate the noise but I don't know for sure if there is a downside to doing this until the new Ref 50 comes in.

Any power experts out there?

Bundy, I hope the problem is just with the unit itself. Ground loops are a pain, but using a ground isolation transformer (MAGIC) on the incoming cable TV line eliminated all my ground problems and I do not need cheater plugs. Good Luck.
