What makes you think this will work, at any power level ?
Because for a few years we had a guy who would drive up and down the
road with an amplified CB radio. This would come through load-n-clear
on any device connected to a speaker as long as it was in the on
position. When the device was off we'd never hear the CB guy talking.
Uterly different technology.
Basically yout hi-fis were shit and had no EMC capability.
Solid State electronics inherently have low EMC tolerance; Vacuum
Power on the other hand had a much higher EMC tolerance.
Only because the higher rectification threshold makes it more tolerant.
I've designed pro-audio mixers that we tested for EMC sensitivity in the CB
band by using a handset right next to one. Not a sqeak. It's simply good
(grounding) design that's needed.
