[Milsurplus] RA-62 supply specs ?

[Hue Miller]

I found an RA-62 power supply in my storage. I am 
pretty sure this is for the ground version of the SCR-522
radio. I could not find much on the internet, certainly not
the specs. I don't plan at all on acquiring an SCR-522 type
thing so will either dispose of the thing or try to use it to
power something else. What high B+ can i expect out of
this?  Tnx - Hue Miller   K7HUE
