mi I'd vote for TDR. Know anybody who works for the cable company or the
mi phone company?

mi They make gizmos for finding hot power wires in the wall. Can get 'em
mi at any home depot. I'm guessing they just pick up the hum.
mi Don't know how much AC voltage you'd have to put on
mi your speaker wires to be detcted or whether that would be safe. You
