HI Jack...
First of all, I apologize for the lateness of this reply; I've been out
Hoping you all will have some good ideas on a cure for this problem.
I am hearing AC hum in my monitor headphones - ONLY when transmitting.
The hum comes and goes instantly when the KPA500 is switched on/off. Same with
other headphones. No question it's related to the amp but not necessarily
