I have a pair of yellow "door knob" caps that are marked HI-Q HPA 55 N7 50
500PF 10%. They measure 2-3/8" diameter x 5/8" tall and have a 1/4 x20
threaded hole on both sides. They look like they could be really husky
caps. I need to know how many volts these things are rated for. I plan on
putting 2 in series to use on a Butternut HF2V. The one that is supplied
with the antenna is 200pf @ 10KV and I need more..... I have seen similar
looking doorknobs used in the Emtron amp. for blocking caps.
