The OA2WA tubes have only two of the pins connected. So power goes
in one pin and then out the other to the next OA2WA tube and so on. It
looks like there is no output from the last tube in the series. So
maybe this is why the caps won't charge.

I cannot see properly from the photos - but is there a connection to
the last (bottom) regulator cathode?
I would guess it might be to chassis so "no output" is correct.

If all three glow then the voltage across each should be fine.
