This is wrong...I keep getting turned around in the heater wiring forgetting that it is connected to ground...

Quick update: I tried a power up with the time delay tube removed to
permanently disable B+. It tried to start but popped the fuse shortly. I went
looking around the 100V rail and the heater supply, and found a suspected
shorted filter cap in the heater supply, C786 (100uF). It reads basically a
dead short (couple of ohms) at DC on an ohmmeter from + to ground. I have not
removed it from circuit yet, but various tests in-circuit are not promising
for this cap.
