these sound like some caps I bought at the TRW swap meet locally - I put two
in series and use them on a 15Kv 30ma coil - after running for a little while
- say 15 seconds, the caps have warmed up a bit - I would speculate from that
observation that they would fail in extended use, and further that they are
eating up some of the spark energy. So, yes you can use them, but make sure
they don't overheat.

Hi and thanks for reading my request.
I have just picked up some capacitors, 3 to be exact from one
of our local surplus places and I was wondering whether these
could be used in a small coil. The coil that I am building is
4" Diam x 18 long being driven by a 15kv -at- 30 ma neon transformer.
I was hoping to put these in series but before I made up a support
for them, I thought I had better ask the experts if anyone knew
if they were any good or not.
The capacitors in question are described as follows:
5.75" long x 1.25" diam
Body is brown in colour with a screw terminals produding one from
They are made by CONDENSER PRODUCTS
.0125 UFD -at- 25000 VDCW
Model number KMOB 123-25MN
There is also another number printed on the body as 1210-107.
If anyone knows whether these would work or not, a reply would greatly
