I made a little mistake the other day when I quoted what the internal inductance
of these 20 KV, .025 uF Condenser Products commercial capacitors is. I told you
that it was under 80 microhenries. WOOPS! I meant it was under 80 nanoHenries.
I went ahead and confirmed the internal inductance with the factory. It will be
between 30-35 nanoHenries. This is fully acceptable. A nice low figure
actually. The other companies figures were a little higher. They others were
in at about 70-80 nanohenries.
Here was Malcom Watts' message to me.

Sorry for the error. Thanks for catching it Malcom. Your right, it would be a
problem.
