I picked up a transformer with basically 4:1 step up. Surplus place said it was designed for a 500v primary. The manufacturer won't release the specs as it's "propreitary to the OEM." I figure with a nominal 117v primary I'll get around 500v unloaded. Add a full wave bridge and I'm around 700 unloaded. The only filtering I can see would be a choke? for something like 807s 811As that can handle that high a B+, is a single resistor-choke acceptable somewhere between 7-14H?

Store said this was a several kilovolt transformer for a laser. Research says it comes from Cooltouch cosmetic laser, but I can’t find anything else about it. It appears the white leads are primary (and they’re floppy like rubber hoses) and the terminals on top secondary. I can’t find anything else. I can certainty inject a 1 voltish AC sine wave and measure what comes out the other end but any insight appreciated
