Here it is.
The theory proved correct, the Candom leaks the potential to the case.
Once taken off and then soldered without touching the chassis, the hum stops completely.
The case measures 123V to chassis which indicates that the leakage occurs right at the top lead where it is 125V.
I am going to completely open it to look for obvious reasons, and if not found, I will replace it.
The problem is, the main wall and the screw hole are actually the Candohm itself so there is no complete box to restuff.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
