I have been experimenting with different break rates, ballasts and primary 
capacitance values using PSpice simulations on the PC. It's possible to get 
the same energy transfer over one cycle to the primary capacitor by either 
using a small cap and high break rate or a larger capacitor with a low 
break rate but more Joules per bang. For example a 56nF charged to 6.3 
Joules at 550 BPS compared to a 70nF charged to 35.8 Joules at 100BPS (50Hz 
supply) gives the same energy per cycle, I worked this out by multiplying 
the individual bang size by the breaks per cycle. I am assuming that the 
larger cap size is preferred, as the ratio of the primary to the secondary 
capacitance is greater with a big bang to boot. However with the low BPS 
the cap is charged to over twice the Voltage adding greater stress (eg 32KV 
compared to 15KV in my case). What's the general consensus on this?
