Thanks, and it does get confusing,

I see the Rider's BC Resistor data you mention listed at 180 ohms on this site page 18,19:

I also see part for BC Resistor here part 03079 (which I cannot find specs anywhere as of yet) - this might possibly  be the one with 180 ohms.

But delving deeper it gets more confusing as on this site it lists part 5125 which I can find on the Philco library as 240 ohms.
Library 5125 - https://philcoradio.com/phorum/showthread.php?tid=21836

These service bulletin pages show date of May,1931 and the 70 has 240 ohms listed, page 51,52:
Service Bulletin - https://worldradiohistory.com/Archive-Sc...letins.pdf

If yours measured 240, maybe it was replaced perhaps? Or is this a mistake where they took the 180 from BC resistor 5667.
The later 70's above the b22 show another part number as well.
The Philco library all show 1933 as the beginning year for the BC Resistors.

Maybe someone can find the original part number. Being that where it is in the circuit, how much difference would it make?

Edit: Page 55 of this site ,dated Dec. 31, lists it as part 03079, different from May 31 bulletin.
