NEW 125KVP XRAY TRANSFORMER! But I need help identifying

[breezetix]

(Copy pasted from my post on Tesla coils and high voltage group)
Did some research on the GE AMX 4 Portable machine, the xray transformer seems to be a 1kHz transformer (50V & 60Hz it starts saturating, makes sense)
Links to diagrams/schematics below (of the transformer and wiring etc)
But the problem is, I can't seem to find any rated voltages for the primary at all.
It seems to be battery powered as well, uses 9x batteries for at least 110VDC (I thought for the motors only) It appears to be SCR resonant driven, given that it has three SCR bricks (one has both gates, the other two only have one gate each, which is probably the bridge rectifier, at least used that way).
I'm hoping that it's not lower voltage input (like 100V+ or something) but rather like 250V or so, because, well, it's 125kVp 100mA constant, 320mA intermittent, and that's 12.5kW continuous, 40kW intermittent. The primary terminal brass screws are actually not that thick/big, they look like they can handle at least 30-40Aish continuous. 12.5kW at 120V is over 100A. 50A at 240V.
However, with some more testing and measuring output voltage, it outputs about 1kV DC @ 2.4V input so about 415:1 turns ratio ish, that's 240 x 415 = about 100kV. Steve Arcs (Tested to Destruction on youtube) said 125kVp is about 90kV rms. I would like to believe that. Note, there is no capacitors in the transformer tank. Only HV transformer, filament transformer, and a HV full bridge rectifier, that is all. It is most likely about 240V ish, or more, but I need to confirm that to be sure, I don't want to kill it.

So, is it actually about 90-100kV rms? Is there anyone who is familiar with this transformer, and have used it, that knows how much voltage the primary actually uses? I just want to drive the transformer without any issues, without killing it.

It is an GE AMX 4 Portable. It uses batteries.

Start at 8 pages, in the "High Voltage Module" section, it says "1 KHZ INVERTER"
Page 12, it shows the schematic of the HV transformer.
Page 13 at the top ("PRIMARY VOLTS - and +") is obviously the HV transformer primaries input.

I once did a teardown of a very similar, but earlier model, the AMX-II.

Seems to be very like it, 120 VDC battery pack, transformer is driven directly from that at 500 Hz SCR inverter.

See 3 to 6 minutes for transformer details.
