G'day Gary.
I went on ebay and found some 22pF units and used 3 of them in parallel
between two plates and inserted them into the spot where the sigle cap
was in the antenna. It works extremely well.

Subject: [Amps] Looking for a 68pF 7KV HEC doorknob
Anyone have a bunch of doorknobs& wants to sell just one of them? My
backup Butternut antenna had some damage from a falling branch
hitting it, pulling the tabs out from the inside of the ceramic and
pulled the 40M cap apart. I haven't tried to repair it& see if it
will slide back in together properly but I should try that& see if
it runs or smokes. Assuming it doesn't go back so nice, a nice pull
would do the trick. Alex is not available at the time& I'd like to
get it working somewhat soon.
I need the 67pF value& closest I have is 160pF, 300& 500pF in
ceramic doorknobs& too large. I do though have a Fixed vac of 105pF,
80pF and a 50pF fixed vac. I suspect could get some partial use out
of those but the antenna would be detuned for sure
Let me know off list if you have something to fit or, how to
mechanically repair a HEC cap that has the fingers& baseplate,
pulled away from the inside& it's not working.
