Mike;
This particular set uses a Loctal cousin of a 35Z5 called a 35Z3 which has no pilot lamp tap on the heater, these sets use a 120 volt candelabra bulb for a pilot lamp. These sets have six tubes, one is a 12.6 volt, on 35 volt tube, a 50 volt tube, and the remaining three are 6.3 volts, all at 150 ma. So 116.5 volts total, if it uses a 35Z3 it's a code 122, if it has a 35Z5 it's a code 121 both versions seem to have that 80 ohm power resistor https://philcoradio.com/library/download...20Book.pdf
