Ameritron sells the 170pf doorknobs used as input padders on 160 but they
arent cheap. The value isnt that critical.

Subject: Topband: Fixed capacitor source needed (150pf 5KV)
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
