RE: [TCML] Maxwell #31915 colossal pulse caps

[Hans Schattenmeister <klugmann@xxxxxxxxxxx>]

I bought 3) 115 uf Caps rated for 25kV. they are in parallel, looks like I have the capacity to hit 107.8 kJ. so far I have not gone above 15kV. That is about 38.8 kJ. it sounded like a sonic boom. in fact the windows upstairs rattled.
