I have a Henry Amplifier that uses two 3-500Z.  a Model 2K floor
Mounted. I get a Lot of Complaints of a Very large "AC type Hum" on CW but not on SSB. This is confirmed by several different operators in Europe by Switching Modes, and Bands. Could it be one of My power supply Capacitors in my Power supply is going Bad? I have eight of them in this AMp.

The caps are most likly as the hum on SSB would only manifest it self on peaks.
