Another point to stress is that like all gas rectifiers the tube has to conduct into something that will limit the peak current. When conducting the plate curve is vertical to negative, the unlimited current will soon destroy the cathode. The heater transformer can be setup as an auto transformer with lots of leakage reactance. That effectively limits the peak current while conducting.
If the Tungar ran straight into a battery the results would not be good.
