My guess would be a popped fuse due to a blown power tube. I could be wrong though.

The fuse checked good, I will take the amp out of its cabinet so I can see if a resistor or something is bad.
Thanks for your help.

on the re-issues you need to check the solder joints on the tube heaters first. (or second after checking the "cold" tube in question, it could be bad and that'd take care of that part).
But even w/ only one functioning power tube you should still be getting some sound out of the amp.
When you say you checked the fuse, do you mean that you tested it for continuity w/ a DMM or just checked it visually? Visually won't always cut it, you need to check w/ a DMM to make sure the fuse is actually passing current.
