Thanks Kalee. I was going to do a similar thing, do primary of (say) 500 turns. Then wind on a secondary of ( say) 50 turns. I was going to apply 24 volts or so, and see what the resulting output was. Hopefully I could then find out the volts per turn.
I was wondering how to make sure I wouldn’t draw too much current. Now I know!
I hope to knock up a test transformer to get the 950 volts just to see if the scope works. It was working until I turned it on one day and the fuse went. I’m going to check for shorts etc. beforehand.
I shall probably end up using one of those little EHV supplies for the permanent fix.

I’ll probably insulate between each layer as I wind. It’ll be a good academic exercise anyway. I may well do a few practice low voltage ones just to see if everything works out.
