As a follow up on the original volume control not shutting off the amp, I had a chance to review the schematic.

There is a 25uF cap connected to the CCW terminal of the volume control that carries the signal to the pot. If this cap opens up or loses value the signal will no longer be shunted to ground when the control is turned down. So if the pot is clean and checks out resistance wise, check the cap.
