Reforming 1st cap....10uF 450V...they called them "long life" for a reason I guess, this one is 40uF measured 44uF.
Of course it is leaky and is getting better.
I only had a 130V Variac and a rectifier bridge and it is not enough, though I got 200-some volts out of it and brought it down to 13uA leak.
Reforming needs to be done close or at rated WV.

Then I realized I only need two diodes and two caps to make a doubler so I quickly (2 minutes) twisted together two caps and two 1N4007 and got me a doubler....right now working at 300V and can go to 380V which is closer to 450V than what was before.

Almost 400V of bare wires in front of me on the table.....nice!

IF can wire size and Rubber mounts?
Renovated Radios do carry what you need. As for the voltage, a wire should be at least 300V-rated.morzh — 11:13 PM
