Let's try another approach based on the wiring as you describe it in post #1.

Switch to gram and touch the centre tag of the volume control with a screwdriver blade. You should hear a hum or buzz.

Repeat, touching both connections to the WC switch and both sides of the resistor connected to the top gram socket.

If the buzz disappears at some point there's your fault.
