No there isn't an 80 Ohm candohm resistor in the versions with the 35Z3s, which I don't understand since it is in series with the heater string in the code 121 version. I thought that maybe it was in parallel with part of the heater for the 35Z5, it was quite common to do that in sets with the 6.3 volt pilot lamps.I would guess that the majority of resistors were either 1/4 to 1/2 Watt, and the larger ones being 1 or 2 Watts.
