I don't think that anybody indicated that the tube was actually used as a ballast, only that it occupied the same socket location as was occupied by the ballast in later sets.
I would love to see a schematic for the set that Timmy has, but very likely the schematic is close/same as that of the TV-149, which has an 80 ohm dropping resistor in the heater circuit and also a selenium rectifer as well as the 25Z6 and 6X5.
