Well I tried that work around, still no sound. I found what appears to be a capacitor, small square can painted green. One end was grounded, the other end connected to one of the round wound coils. It looks like the cap leaked.
There are no markings or stamping on the can
Also the volume control does not change the current to the tubes, although the control seems like it's working via a ohm meter. Tube brightness stays the same regardless where the control is.
