Where does the current come from?

Mikwy B mentions looking at some spice sims below and I have been staring at these for a few years now. I'll just add the sim results and a few Key points.

The circuit can be seen in all of them and the file is a 20hz sine followed by a the cannon fire from the 1812 and then a sine again. The only change between the two is the final PS choke is changed between 10hy 150 ohms and 1hy 10 ohms. (both chokes are ideal which is a can of worms for another day) The 2A3 is biased up close to RCA book points.

Voltage at the grid of the 2A3 and at the output.

I renumbered the devices in the file below to match L1, L2 etc. to make things clearer for future and the link to it is below. The 2A3 is from Stephie Bench's drop down models.

(edit) to add some more tinders... here are the plots for 10hy on both chokes.
