I would experiment with running it off battery power (if possible) and move it around and see if there is any change at all.

Sounds like there may be a contact issue between either the power input and case. Or the circuitboard and the base plate. Or it could just be a bad pot.

Try it on battery (batteries last forever in the things. Running one on a powersupply seems pointless they draw so little current).

If it still hums gaffatape or insulation tape the inside face of your baseplate and the surface directly under the circuitboard. I've never had a problem with gaffatape as a insulator for these kind of minimal shorts. Don't use it to insulate a 240v power lead though.
