Again,
         I would not like to be accused of laying prior claim to this 
idea. It was in fact reading a post of Richard Hull's that gave me 
the insight into the true nature of cap failures. As far as the 2kV 
figure goes, I picked it as an easy one to build for available 
insulation without the cap section getting too large. In fat the 
lower one goes, the more promising a dry-fired design becomes.
