Hi Michael,

	I have been working on this.  I think the largest physical cap size around
the 18nF/1600v range will work for just about anything but testing is still
going on.  Some pics of my experimental cap in this area are at:

Those are 0.018uF 9 cap strings in 10 rows.  Each row is 2nF at 3 amps. 

Cheers,

	Terry
