The capacitor that causes the board to keep blowing the HOT is located behind the HOT heat sink 47uf at 16v across two low value resistors (value varies with version of the board. This capacitor was a CX meaning it was related to safety.
Run the set 15 minutes remove power check the temperature of the HOT heat sink if more than just warm replace the capacitor.
Later boards were reworked to eliminate the 2 resistors and capacitor in parallel. Note the driver circuit was also changed.

R3324 replaced with a jumper.
R3334 0.18 ohm 3w
9-160-05
R3324 0.33 ohm 3w
R3334 0.18 ohm 3w
Have problems reading the copy I have may have the numbers wrong.
The 0.18 ohm resistor is on the emitter of the HOT.
The 0.33 ohm resistor is between the base and the horizontal driver transformer.
