When I was getting the Johnson 500 up and running, it kept blowing fuses on the high voltage side. I put in a brand new set of 866's , and it stll did it. Phil suggested I replace them with K2AW diodes, and I never blew another fuse. They aren't plug ins though. I remove the tube sockets and mounted the diodes on the chassis with porcelain stand offs. hvp16-high-voltage-16000v-750a-single-phase-half-waverectifier-diode-168384n.jpg
I think the current is a little high for that device. 750Ma maybe?
