plate transformer

[KD8PNE]

Picked this transformer up from a local completly sealed in a box except for taps has 10 taps label reads 1-2 115v 60c ,3-4 3100vrms@150maac, 5-6 6.3 v 1.5a, 7-8 6.3v 2a 9-10 6.3v 2a  made by transformer tech inc.does anybody have any info  pulled from some military gear thanks kd8pne

What would you like to know?  All the data is right there that you need.  Maybe you would like to know to what piece of equipment it was from?  That would be hard to say unless someone can recognize it as being from some piece of gear they have seen before.  But from the current rating on the secondary HV, it doesn't seem to be good for any amount of power.

With about 50% efficiency, that plate voltage at that ma would output around 230 watts. That's 100% transistor and FET territory these days.

Well I'm sorting thru junk lying around transformer weighs 30 lbs just didn't know if I't would be useful for anything other than scrap or a boat ancher just hate to get rid of that might be useful to some one  maybe somebody in to the audio valve stuff might find it handy don't know

Somehow I cannot imagine a 30 lb transformer being rated at only 150ma at 3000 volt.

Yeah me either that's why I was scratching my head I'ts completly sealed boxed in with ends sodered on, taps sticking out insulated with porcelin insulators we weighed it at about 30 1/2 pounds

Its also unusual that it has three separate 6.3VAC windings. I expect it was used in some special application (medical perhaps) rather than a normal transmitter or amp.

It was something military everything was od green came with about 20 prince albert can caps all od green, transformer has the typical yellowed lettering that you see on military equipment labeling
