Raliegh, if pin 1, 7 & 6 (heater, cathode, plate) are shorted you have a direct connection of one half your secondary HV AC across the electro cap (76) then through resistor (78) to ground. That should be enough to fry it. Tube must be bad but also check as Ron said and make sure the socket isn't shorted too. PL
