[Hallicrafters] HT-37 Main Transformer Voltages

[Bill]

I was just performing a voltage test on the main transformer (without tubes)
for this transmitter intending to assure the transformer is operating ok.
As I was bringing the voltage up slowly and monitoring the plate leads AC
voltage for the HV rectifier, at about 75vac input, I was already over 1kvac
on these leads with a lot of variac left to go.

I have the service manual for this rig and it specifies 750vdc from the HV
rectifier tube but no where can I find a voltage chart for the AC voltages
from the various windings in the main transformer (except filament).

Does anyone have any info on these voltages?  I know there will be a large
voltage drop across the rectifier tube, but it seems to me, if I apply full
line voltage to the main transformer, I will probably get about 1.5kvac out
of the transformer.  Is this correct?  If I use a solid state replacement
for the HV rectifier, which would have much smaller voltage drop, I may have
too much DC for the Final plates.  Any info greatly appreciated here.
