[Amps] Big transformer request TSPA

[John T. M. Lyles]

Before I start searching for 3 KVA pole pigs I will ask here. I have 
a UTC LS-184, a beautiful transformer from the 1950s, weighs 102 lbs. 
It is 7 kV RMS CT. With a choke input, it would do a 3 kV DC 500 mA 
supply all day long, according to UTC. I need ~ 4 kV at 0.6 - 0.8 
Amps. If I ran it into a capacitor only, and it charged up to near 
peak, it should do the voltage fine. However, I am not certain how 
much current derating it would need for running into a Capacitive 
load.

Does anyone have a single phase plate transformer, which has 220/240 
primary and good for ~4 kV DC @ 0.6-0.8 Amps? I would prefer to us a 
full wave bridge but two diodes and a center tapped pig would work 
too. I just found a 4.1 kV @ 2 Amp today at a junk yard in town, but 
it has 480 VAC primary, and is LARGE. I have several pieces for 3 kV 
DC supplies, but nothing for a higher voltage tube. Numerous 
broadcast transmitters and RF industrial generators used such power 
in the good old days.

There were some very nice 3 kVA 4160VAC/220 dry distribution 
transformers made by Westinghouse years back, before ABB bought them, 
and they outsourced to China. Into a choke, they would be fine. I am 
not planning on using this for SSB.

Thank you.
