  I have bought 4 of these 0.03 cap's off e-bay 3 months ago.  Two of
them are in series in a 1 kW Coil for a capacitance of 0.015 -at- 70 kV. 
This is over rating them a lot, but they should last forever in this
Coil.  The farther you run a capacitor under its name plate voltage, the
longer it will survive.  They are compact, and run very nicely.  Buy from
the guy on e-bay, I believe his company is TSR?  He is dependable & makes
an honest deal in my opinion.
