Not a guitar person, but the question about different volumes is a good start. I couldn't find the exact model based on what was listed to look up a circuit diagram. Possible tube, capacitor, power supply rectifier diode, bad solder connector.
Pull the tubes to test if you can get them tested locally, or replace if you can get them cheap. Tubes in amps under 10 years should be a little more reliable. Too bad there aren't testers in grocery stores any more like the 60's.
