Very cool...for radar testing I presume? Guessing since it says made for the Navy.

When I did some more online searching for a manual I found two references to it being used for Sonar tests.

I looked at the datasheet you linked for the 7534 output tubes--quite impressive. Before this, I was unaware of frame grids in power tubes, which gave the 7534 a 25 mA/V transconductance and very low screen current (4 mA).
Back in grad school, I used Delco high-voltage TO-3 transistors (higher voltage part in the same series as your DTS-423) to generate 1000 V pk-pk deflection waveforms, using a cascode totem-pole output stage.
Running bipolars in common base mode (cascode output stage) allows you to swing the almost full base-collector breakdown voltage on the device so long as it is not in a high radiation environment.
I fired it it up again today. Here are some output waveforms into a 50 Ohm load. I used a 20W 20db attenuator into a 2W 20dB attenuator into a 50 Ohm feed through termination.

I was looking again online to see if I could find a manual for the SG-816/U High Power Pulse Generator. I have not, but I did find specifications for it:
