Tnx Terry and Paul for all the infos,
I will go for the newer design :)

Instead of doorknobs I am gonna use series of 6Kv ceramic caps,
am I going right ? I will use 2 25W resistors of that type with
the heat sink (they are like gold plated), excuse my poor english
but I do not know how you call it... I read about wire wound ones.
Are these the same in in this application ?
Also I have not found MOVS of 1800V/2500A
They have only small...There is anything to dismantle to recover them ?
Or any place to order in Europe ?
For the safety gaps I am recovering some old computer mice,
the ball inside is made of steel or at least of iron.


Tnx again 4 help
Daniele
