Rodney, those caps are metallized polypropylene, meaning film 
construction.  These are not good for pulse duty, which is corroborated by 
the listing of "fair" on the electrocube web site.

If enough people are interested in a larger "Geek Cap," we can get some 
ordered.  I believe our minimum order is 250 pieces, and can get any CDE 
cap listed on their web site.  I believe the largest single 942C series cap 
they have is 1600VDC, .68uF.  Specs look good, although the dV/dt is half 
the current offereing of 2kV, .15uF.
