Gary,
I've been out of town and just returned. I checked my doorknob inventory and
have a 63pF/4500V, 5 % tolerance doorknob cap, made by Jennings. It looks
just like the Centralab common 858 series, I verified the capacitance as
63.4pF. If it would be of use to you, let me know and send me your mailing
address, and I'll send it to you. No charge.
73,
Jim W8ZR
