I could try replacing that disc cap I suppose.
Dosnt make sense. assuming 4 is "hot" 5 should go right to GND.
Check ohms should be 0 at pin 5 to GND.
May be a miswire here. If not sounds like the SKT.

Gotta concur totally. That's assuming the heaters are parallel-wired and one side of the heater supply is grounded. If pin 4 is hot, then pin 5 has gotta go to ground.

I screwed up. It does go to ground. It's hard to raise the chassis up with the picture tube in it, but I got a better look this morning. Going to check continuity on the pins of the tube with the tube pulled out slightly and see where I'm at.
