That cap is a TV doorknob used because they were dirt cheap and not RF rated
thus the serious overkill in voltage rating. Use a 1000pf 5KV RF rated
doorknob which is a readilly available value. If you really need 1200 then
add a 200 in parallel as 1200 is a non standard value. These doorknobs are
common in 1000W + amps.
