Peter, what is R? Is it the internal dc resistance of the NST's 
secondary winding? If so then I would have to 1/R=1/R2+1/R3 etc. to get 
R when using several units? I will most likely be using a few 12kV 60mA 
units. I have 3 of these plus two 30mA units. I would be using my 15kV 
units but I ordered plastic for my cap befor I got them and dont want to 
apply that much voltage.

Danger! 250,000 Ohms!
