I missed your comment earlier that the volume is invariable. Basically that means that your first gain stage is most likely fucked and the guitar is bleeding through a little bit to the later stages that have no gain control. Until you get a new 12AX7, you might try rotating them to see if the failure mode changes...

EDIT - Everyone kept mentioning the hum as being normal on these. Just out of morbid curiosity does anyone know if the three position ground switch shown on the back in the manual actually helps reduce this hum like the manual claims it does?
