Re: [TCML] Maxwell #31915 colossal pulse caps
I use 2 or 3 of the .3uF 35kV ones in series, 37687. So far so good.
I have four of them but one of them is sort of yellowing and I think
that's because there's a leak in it somewhere.
My capacitor box lets me short one of them out for .15uF @ sync versus .10uF asrg.
