The filament transformer is pulling almost 2 amps and the plate is
pulling the rest (9-10 amps).

When we attach spinners to the top electrode, we can see the
strobing of the discharge representing the positive half cycle
(in this case a doubling of the positive half cycles since we are
running unfiltered DC). As one would expect, there is a short
"off" duration as the AC waveform dips to zero. This off period
seems to be responsible for the "remanufacturing" of streamers
as we see twice as many as compared to AC operation.
