GAP Pre 73 hum (joining the club)

My hum:



- with nothing in the input

- via either the XLR out or balanced out

- at 120 and 240 Hz

- even with output knob turned all the way down

- there are a couple of "sweet spots" in the input and output knobs where the hum is still present, but not as bad

- does not change by moving around the transformer

- is present in four different houses

- is fixed by Waves X-Hum with the "60 Hz" preset



Any suggestions? Would love to fix this on the hardware end rather than with software.
