Did you keep your old pot? If not, please do in the future. Lets face it, an enterprising amp tech will use anything to get it working & often sounding better.
As to reverb, take bag off. Slightly loosen 4 screws. Should introduce some chaos. There will be a # please copy if you replace bag. These numbers are in/out impedances, and must be adhered to. In the event you decide to buy a new tank. 25 bucks max & caveman easy to install.
Look up valve position & replace with AT7. This is a function valve with more compatable MU factor for driving a reverb.
To guesstimate age of tubes, paint & pins.!
