Thanks for the advice Ron. I did go to a meeting they had last fall, it was a big radio convention in Livonia. I met a few people but none lived very close to me. I'll reach out to them again, maybe someone will be willing to help.

As far as the low voltage, I took Brenda's advice and connected a resistor to the two ends of the filter choke to complete the circuit. I soldered the points in and re-measured the P-K volts across the #42 tube.

The measurements prior were 0.00 volts and after putting in the resistor they were 0.02 volts...not a real big jump.

In any case, assuming I do need a new filter choke, how do you assess which one to buy if the parts list on the schematic is not conclusive?
