Hum hum hum


I have connected my NOS PS Audio gca 250 to my PS audio pre. Disconnected all inputs and I get a distinct hum at high levels on one speaker with just the amp/preamp/speaker connection. . Swich the xlr cables and the hum goes to the other cable. I probably will never play at these levels, but I would like to trace and fix the hum. Any ideas? Thanks.

What exactly do you mean by switching cables, and hum goes to the other one?

Does this mean the hum is going from one side to the other? If so, bad cables. :)
