[Milsurplus] PP-106/U info needed.

[Kenneth G. Gordon]

I found 4 of the subject power supplies in my stash of junk.

These are a regulated HV supply. 

Input is 115 VAC, 50 - 1200 CPS, 1.6 amps max, 1 phase.

Outputs are 90 to 300 VDC at 10 to 60 mA, or 90 to 270 VDC at 
10 to 80 mA, continuous duty.

The pass regulators are a pair of triode connected 1625s.

It also has the following filament voltage outputs: 6.3 VAC at 5 
amps, and both 12.6 and 28 VAC at 2.5 amps.

There is a 0 - 500 VDC meter on the front panel.

The main regulator is a 5R4, and there is a 6X5 bias rectifier, 
an 0C3 regulator as the standard, and a 6SJ7 as the regulator 
which drives the 1625s.

They sure weigh a lot.

Would anyone happen to know what this originally went to?
