[Amps] Henry 2KD-5 120 Hz Hum

[hamguy2]

It could be 60 Hz.  It sounds like 120 though.   A local ham with 
band scope said 60 Hz and not a perfect sine wave.  He said it was 
riding on the signal about 20 dB down.  This is an amp I acquired 
recently and the hum problem has existed since I started using it.

This may be related.  Previously, I also replaced both blocking 
doorknobs.  One of the them was cracked and blew the CB when it 
arced the first time I first used it.
