Re: New Coil

They work fine on 12kv nst's (about a dozen 3-5 min runs and still ticking in a bigger coil with more in series), explode after a few min on 15kv ones (makes a nice 12" blue/orange fireball tho with a big mess).

I plan on using my welder for current control and
either my two 1256's or my three 540 volt 30 amp

but may only use them two deep for 75 nF 70 kV rating,
which is kinda small for a coil this size. I'm afraid
to use them as 300 nF 35 kV, as this seems to be too
close to the edge. I have no idea how rough a life
these guys had before I got them.



I have a couple of those Maxwell caps also, and as you, have been concerned about using only one and have always used the two in series. I have read where lots of folks on this list have the same caps. Is anyone only using them individually, or multiple in parallel? If so, with what power supply? I would feel ok at say 10 kv but both of my coils use a 15 kv supply and I have just been chicken to find out what kind of voltage they can really take.
