I am looking for a user manual, hopefully a PDF file, for this old regulated power supply unit. THIS THING WEIGHS A TON! There are 14 tubes protruding from the hinged back panel including 4 6L6 tubes in tall metal envelopes. I have never seen metal tubes that look like these, but I have seen plenty of metal tubes. I want to take the thing apart just to see what makes it so heavy!
Understandably, there must be a rather large transformer in there, but my God, they must have robbed one out of a 1940s Dumont TV set like an RA109A! Actually the weight would be closer to THREE of those! This thing is a rack mount design and HEAVY duty as I have ever seen. It really makes me think of possibly military use or other industrial applications, maybe radio/television? So far, I know nothing about this unit and don't see much of anything on a web search. Jut gathering any type of info that I can. Any help, comments, etc. would be great!
