SlidesK;
I think you are right about the 80 Ohm, resistor, but why they included it for the code 122 version only I'm not sure other then to cushion the pilot lamp bulb, and the heater tap, when you first turn the set on. It would be beneficial to the tube heaters in either version, running the voltage a little low will prolong their life as the total string only adds up to 116.5 volts, and it's normally at least 120 volts now. That would also explain why they have a paper cap connected across the pilot lamp, which is something I haven't seen before.
