Dan: My PE/oil 400 Amp plate capacitors cost $150 US to build. My .25uf
1000v MMC bank 0f 75 caps cost $120 US and my High energy discharge caps
( 3 each) 60,000 Volt cost $1000 US apiece. My students make thier own to
learn and to minimize costs. Bucket and beer bottle cap are a lot more fun
to build and repair than a $100 0r $1000 single event failier. Coors to you
