Default Re: AC/ DC radios live chassis.

It was somewhat normal for the switch to be in the neutral wire though, because this means that when the radio is switched on the power wiring adjacent to the volume control wiring is at chassis potential, meaning less chance of AC hum getting across and into the audio circuit.
Putting the switch in the live wire means you have 250Volts passing rather close to the volume control..
