Hissssssssssssssssssssss ! or hummmmmmmmmmmmmmmmmmmmm ! or Bzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz ?
Not the same.
If it were a Power supply capacitor problem it would not change by touching the chassis.
When amp is normally on (no spare cable in effects loop) the sound is hiss (maybe buzz when volume is full but I can't try it now because kids are sleeping).
When I put the spare cable in effects loop (power amp in) the sound is Buzzz
No Humm, or if there is, the hiss and buzz are louder and humm can't be heard.
