I have a 15 kV 30 mA NST and 2 of the .03 mF 35kV Maxwell caps that I plan
to use together in series for .015mF which is LTR and pretty close to the
capacitance I have been getting recommended to me and the capacitance I
get from different TC software packages. From what I've read about your
experience, I should be pretty safe with this setup, right?? I'm usually
very cautious about things like this, maybe to a fault but it has kept me
out of trouble most of the time. What do you guys think? Thanks.

PS When the subject changes in a thread, like this one has, shouldn't we
be changing the subject line so people searching the archives later will
be able to find this information? I changed this subject to Maxwell Caps,
in case you didn't notice.
