Hello Herb,
My favorite place for doorknob caps is Max-Gain Systems.
http://www.mgs4u.com/index.html
Taking a quick look I see they have some 200 pF 7.5 Kv doorknobs. If you
don't see what you want, call. They often have parts not on their web page.

I have a Drake MN2700 so I can at least get the amp to work above
1870Khz during contests. The tuner used some fixed flat 150pf 5KV
capacitors to switch in from the front selector as increased capacity
is need to make the tuner work. I can't find any door knob
substitutes at that value in my junk box. I am thus looking for a
source for these values but so far have not found anything that I can
use as a substitute. I presume I could make some out of sections of
RG-8 mini roller up in a coIl but before I try this I am searching for
a door knob source. I have some 500pf at 5KV and three of them in
series might be close enough but i still need the correct values. If
any reader to this knows of other ATU manufactures that use the copper
teflon flat capacitor in their units maybe could order 150 pf 5KV
from them.
Your help on this would be appreciated.
Herb, KV4FZ
