I know that I can make it that way but then I will only have + 185KV  and - 185 kv relative to ground.
But if I can make it the flip over way and run it from either end then I can get + 370kv and -370kv relative to ground.
I just want to know if there will be any problem with the unconected capacitor in this configuration.
Thanks gsm

@gsmsslsb,
Now I understand what you're trying to do. Very clever. Guys, go back and look again at his Reply #11, if like me you didn't get it right away. If you make the flyback connections at X then the diodes all point one way and if you make the flyback connections at Y then the diodes all point the other way.

I don't think the extra capacitor will matter since the other side of it will not be connected to anything. You will have to pay special attention to how you terminate and insulate things and how you make polarity changing switch terminals, especially at 370kV. That's some serious voltage for this type of circuit. I've only ever done 75kV.

As for insulation I am looking into potting the whole thing in parafin wax.
Melts at 45 - 60 degC I will just have to check what temp the components can handle then get the wax.
I am feeding with a 15000 volt neon transformer and have 19 stage CW cascade so taking peak to peak voltage I should be able to get ove 300 KV.

Paraffin might be okay in terms of cost and availability, but a short to ground could be dangerous.  Paraffin burns; that's why candles are made of it.

Years ago, paperweights were made with pourable neolite plastic that had objects of interest embedded in it and allowed to harden for a conversation piece.  Can you find and use neolite?

FWIW I use mineral oil which I bought years ago in 500ml bottles at a pharmacy/drug store. They normally sell it as a laxative I think.

Very hard to use a ladder over 100kv it will flash over everything and creep back over the diodes etc. Years ago i used clean engine oil it works fine. Gives about 3 times voltage rating before breakdown so if you had problems at say 50kv it will run to 150kv with the board submerged in oil. I used a tuppaware box filled with oil and put the lid on and used spark plug ht cables thru tiny holes in the lid far apart on the width.

  Better to add just a few stages to NST then finish off with a large tesla coil that what they are made for!
