I recently sold my Bag End Infrasub 18 and the new owner is reporting a hum coming from the amp. It was not there in my system so I am trying to troubleshoot possible causes.
He says it is there "even without hooking it up to the preamp."
I suggested trying another wall outlet and hooking it up to the rest of his system in an attempt to isolate something.
Anyone have any ideas? I've never heard a hum coming directly from any components before, only the usual ground loop issues coming through speakers.
