We pretty much now know Steve does not have 3 dedicated circuits.
We know that the 2 gang box for two of the 3 circuits is a 3 wire multi-wire branch circuit.
We know that there is only one equipment grounding conductor for both duplex outlets.
We know if Steve plugs in his two amps into just one of these circuits, (one duplex), he does not have the hum problem.
We know if Steve plugs an amp into each of the duplexes he gets a hum...
We have been calling this a ground loop hum....... Hum yes, but maybe not from a traditional ground loop. Any ideas? Your thoughts......
