Re: Cretinous idea - The combined volume pot and mains SW.
Quad managed to put a mains switch ganged to the volume control in the 33, and right next to the disc input circuit board (admittedly with an aluminium sheet screen) without any hum issues.
The Quad 22 valved control unit did the same thing, but had a soldered on tubular extension to the pot around the switch, so effective screening seemed to be more of an issue in that case.
But that is the exception rather than the rule.
