I am told to beware of door knob capacitors in high RF situations such as
the antenna tuner. I need to stick with either a 6 or 10KV ceramic or an
old transmitting mica. I am looking for 1000pf. I currently use two .0003
(300pf) in parallel 3750Wvdc transmitting micas.
I found the 10KV 1000pf ceramic for a mere .62 per each in my Antique
Electronics Supply (the other AES HI). The rub is they have a minimum
purchase. Fair Radio used to have big transmitting micas (I got a 470pf
10Kwvdc several years ago) but the only ones they have are
real big ones now. I will try WB4GNT but he usually has to dig things out
and I am sure he is going to both Huntsville and Shelby.
Does anyone have something in their junk box I can use?
