I have a system that was picking up hum when I moved into my current home, but not the previous home. It's a custom system designed and built by a fellow I've know and used for years (Von Gaylord Audio). When he visited after the hum was noticed, he was fairly sure it was electrical interference. There is a high voltage tower about 200 yards from my home. He built me a set of shielded cables for the pre-amp to amp interconnects. That took care of the hum.
Can moving wire location at circuit breaker reduce hum?
The power line going into my music room will oftentimes make the amps’ transformers hum. I’ve tried many things but have had no luck. If I take any component that’s humming into a different room run on a different circuit breaker, the hum disappears.
Would swapping out the wires that go into the two separate rooms at the breaker make any difference? Or is it more likely that one of the outlets on the circuit that goes into my music room is somehow miswired and is causing the hum? I can unplug everything from the circuit except for my amp and it still hums.
Any suggestions on what I might be able to do short of hiring someone to run a dedicated line?
Thanks,
Mamoru
