mike that cap is 10kv 2200pf as you thought it was .
i use one in my SB220 as a dc blocking cap but its 1000pf @ 10kv , i drive
it with 150w in the 2400v setting for 1kw out and also 150w drive in 3kv
setting at 1.5kw out .
i also use these caps in my 160m shunt fed tower and wil hanlde 1.9kw of rf
on 160m ok .
they are very good caps, just make sure the 5mm screws into them arent too
long because it isnt hard to break the silver solder joints where the
threaded posts are mounted .
