    Default Butternut HV9 doorknob caps ?

    I did a search on the ZED & Google .
    The threads here were closed and some of the links were too old .
    I am looking for some replacement doorknop caps and confirm the values .
    From what I have found there is one - 200pH 15K & two 67pH 15K ?
    Looking for a min. of one 67pH 15K , but since they not so easy to find info & source a set would be nice .
    Thanks John

    Usually you can get them from Bencher/Butternut.

    RF Parts has some...

    Should be "pF," not "pH."

    Steve I was on the Bencher site before in needed them and saw they had them now I go back and can not find on there site .
    I am under the impression they may cost the most there , from others comments .
    Once I got some values off other threads , I could not match at RF parts the values ?
    I just pulled out my notes and I have the correct pF on them , a short circuit to the noodle
    Thanks again

    RF Parts has the 200 pF 15kV cap listed there; they have 67pF but only at 7.5kV. I don't know if that's a good replacement or not (for 100W operation it should be; for 1500W operation, maybe not).

    The Butternut P/Ns for these are:

    200 pF = Butternut P/N 290-05
    67 pF = Butternut P/N 290-06

    You might call them on the phone and ask how much they cost.

    I'l check those out , as far as power , my rig is misbehaving , refurbished Yaesu FT 897D and it is putting out 3/4 - 3 watts depending on band etc.
    So should be OK , I do have a couple amps Heathkit SB-201 & Collins 30L-1 that I received non-operational and they seem to want more than a few watts to drive .
    Now to get another HF rig so I can dig into the 897 issues .
    So I will want to go to higher power .
    Thanks again John
