Hello Mo,
I know its a daft question but have you got the volume control plug the right way around, are there wires in connection 1, 2 & 5 or have you made up a test volume control using pins 1, 3 and 5 (pin one is linked to pin 5 and goes to one side of a 10k log pot and pin 3 goes to the wiper on the pot.
Regards
Alan
