Hello
I've had an ICBM in my system for quite a while. I installed the ICBM at the same time I got an outboard amplifier. I noticed a hum but thought it was the amp or the electric line. I had the line checked for continuity and voltage. Corrected a bad neutral ground. Swapped out the amp, and the hum is still there. Now I'm looking funny at my ICBM, especially its little transformer. Anyone have any system hum problems caused by their ICBM?
