Upon opening up the unit. The two vitreous enamel resistors I used as plate
fuses had melted and broke. Also, the large doorknob blocking cap had split
open and was blackened. There was no other obvious damage or signs of
distress. The plate choke looked unscathed. I had previously direct
grounded the grids and removed the grid chokes. The underside of the tubes
looked fine. I regrettably did not check the bias zener.
Plate doorknob cap failed shorted?
Just one possibility, but the first thing I would check if I were you.
Check your output choke across the plate loading cap, looking for any
obvious signs of damage.
