Ed,

There are others.

I have been running my magnifier system with the "equidrive"
configuration for several years with the same two capacitors. The caps
are rated .1 mfd -at- 45KV pulse for a total capacitance of .05 mfd -at- 90KV.
Total runtime for the capacitors according to the hour meter on this
system is 18 hours! The system output is more linear from minimum to
maximum (4 inch purple streamers to 14 foot white hot  arcs) using the
equidrive configuration.
