Skip...
It looks like R-100B is a heater dropping resistor and it drops the ac voltage to the 110v dial lamp. R-100a I think is a current limiting resistor for the input of the voltage doubler. The lamp is in parallel with heater string not in series.

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.
