Re: KVA Effects former Hipotronics pulse caps

When I get back from vacation in a few days I'll look for more in the shop.
You got everything right. New they'd cost about $1,500 each in small lots...
Wysock designed them and Frank Maximillian (sp?) built them. After Frank
retired the QC went WAY down and after we replaced a few of the "newer" ones
upside down, 70' in the air with a bucket lift, we changed to Maxwell.
