HV- voltage multiplier circuit confirmation needed

[bolt]

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 over 300 KV.

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!
