Hi all ,Mike Church here .I'm thinking about purchasing a large cap but need to know if it may be used for tesla service. Hipotronics does not seem to know what it's duty cycle, pulse rate, or what its dialectric is made of ? These are the # on the cap and I was told it was used in a klystron? set up. MASF-919-314 (HIPOTRONICS) A CAP 7X.O3 40 KV FRQ. PULSE S/N 59EI9 Any help greatly appreiceated,Mike Chruch (CUHRCHMON)-at-aol
