I have a UTC HS-965 power transformer and need specs and pin out. Have looked but cannot find anything on it.
The HS number is a in house number for the manufacturer that used it .
A photo might help and the coil resistances and the wieght .

I have the following
The primary is as follows 1Ato 1, 2Ato 2 120v line goes to 1 and 2A
The secondary is terminals 9 and 7 with the CT on 8
The 6.3 winding is on 5 & 6 no CT
The 5 v winding is on 4 & 3
The is a #10 tap that I don't know what is is.
The AC voltage appears to be 450-0-450 with 225vac on the #10 tap
The primary measures 2.2 ohms as connected
the secondary measures 233 ohms.
With no load with a 5R4 rectifier and small filter cap I get 610 VDC no load.

Looks pretty nice, send to me for proper disposal.. 😀
I suspect the HV secondary might handle up to a couple of hundred mA of plate current based on size and weight. Test with the proposed supply design and load it down and see how much it sags under load, monitor how warm it gets. This might be good with a choke input filter as the voltage is pretty high and the CI will allow you to run it pretty hard.
Monitor temperature and look at the efficiency of the transformer as you load it down for signs of core saturation and excessive copper loss.
That high voltage tap on #10 could be useful for a bias supply..
