James,

Hmm, that's strange because I have some surplus
.1 uFd, 75 kV rated Maxwells (cat# 31885), of
which I use just one in my large SG coil outfit and
I've never been able to detect notable external sur-
face warmth to the touch above ambient temperature,
even after several minutes of non-stop firing at re-
spectable power levels (10 kVA+) from my 14.4 kV
pig. There doesn't seem to be any "delayed onset" of
the internal heat reaching the surface a few minutes
after shut down, either. Certainly can't give that rave
review for most of the previous caps that I've used
prior to the Maxwell unit, though. :^0  {with the ex-
ception of that 100 nFd, 25 kV(AC) rated, BNZ
series Plastic Capacitors unit that I have}.
The downside to it is the very wimpy, 1" long by
1/4"x20 TPI threaded stud end terminals as well as the
obviously brittle phenolic exterior containment. Its "guts"
are tough but externally, it seems mechanically fragile. :^0
Don't drop it on a concrete floor ;^O

Really, I should proof read this stuff. I was thinking 100pps. If you stay 
very conservative on the Maxwells, you can get by with the 1pps caps. They 
are close to death in Tesla coil operation however. I have had most of my TC 
problems with caps. I have a Maxwell 80nF@100kV cap. It gets hot at 10KV. I 
had no luck with homemade caps either. Both rolled and plate types died; 
some quietly, some not. James

Hi Jame

"100Hz Maxwells"? Could that possibly be a typo?
Maybe 100 nFd or 100 kV rated Maxwells? Or
could you possibly be referring to a 100 pps rating?
Please clarify for this befuzzled reader ;^]

Many years ago, these caps came on the market and I bought a bunch. I think
the guy had several hundred. I think they were military surplus. I guess
100Hz Maxwells are your best bet. I have spent too much time and trouble on
caps.

That's sweet! It does seem rather bullet proof.
Where did you get them, I have been having trouble sourcing capacitors for
my own coil is why I ask.



Thanks,
