Power off. Pull 80 tube. Power on. Keep pulling all other tubes one by one to see if at any point the filament volage becomes normal. Also see if your pilot light has a short or the bulb is wrong. If a bad tube, the voltage will jump to normal once pulled.
If does not help, power off, pull all tubes and the pilotblight, and desolder one of the transormer filament leads from where it goes on one of the tube panels. Measure across the filament pins on any socket ( except 80's). See if there is any load present (should not be).
