Hi Eric,
The volume control is going to be a fairly low value as it is in the ant circuit. Probably 10K to 20k should be about right. As Mike said it important to replace the caps and then you can measure voltages to figure out what going on. Without replacing the cap you run the risk of burning up the power transformer which you don't want re replace. It special cause it has a 2.5v filament winding very hard to find.
If you have done the replacements measure the voltage on the plate of the 47. That would be on pin 2.
