Restoring a Predicta Tandem
#4

>If the resistor was open, the tubes would still glow.

If you mean the Fusistor yes this is true.
If you mean R-80 section B if you unplug the tuner to measure that section it could measure open and still operate the heaters  as the tuner heater is in parallel with that section. So the current would flow thru the heater rather than the resistor.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
