ADC Hum-1 Video Humbucker

It accounts for differences in ground potential found in long video
cables, incoming and outgoing lines, and separate power distribution
systems. The ADC Humbucker silences 99.6% of a 10Vp-p, 50/60Hz ground
induced hum in a 200' (61m) RG59 B/U coax run. The precise amount of
hum reduction depends up...
