Nice, thats a lot of current. What gauge wire did you use?
Thanks, the higher voltage one is about an estimated 1kV @ 300mA and the smaller one can do about 600v max using the taps with the highest resistance between them.
Not 100% sure on the gauge as the wire came out of an old CRT's degaussing coil, but I guess its around 26SWG judging by the thickness.

here is a video of it on 40 volts
Very nice
what driver where you using?
The transformer with 3000 turns is by far the best i have made, i plan on making more turns as soon as a get a bigger core.

Thanks , im using the ZVS driver with IRF150 Mosfets , No zener diodes as there is a 12 volt supply for the gate side of it .
Yeah , i was going to make a larger one , im not sure how many turns i used in the end , just i ended up with 9 layers worth , i may try for alot more , but use something othere than papaer as the insulation material .

Im looking into pulling a vacuum on one of them because i have some corona forming between the wingdings under oil.
