K1 capacitor ID help

[dean]

Hi Don,
     Thanks for answering.  The type of capacitor you are describing is
like the ones that I mounted on the four band module.  Those do have a
round body with a flat SIDE to it.  These capacitors are completely
round but have a little square extension on one end.  For lack of a
better description, they kind of look like a banjo would look like if
you cut the instrument's neck off close to the banjo's body.  The round
portion has a contact and the end of the cut-off neck has a contact.
The body is ceramic and not plastic like the ones on the four band
module.  I hope this description can help you paint a picture in your
mind to help explain what I have here.

Dean,

Look carefully, one side has rounded corners while the other side has
angular corners (even though it is smaller). The flat side is the one
with the angular corners.

Dean,

OK, if there is any confusion, use your ohmmeter.
Measure the board to determine the lead of the component that is
connected to ground - that is the ground side, and then with one
ohmmeter lead on the adjustment screw, see which lead is connected to
that adjustment screw.  Connect the adjustment screw lead to the ground
lead on the K2.

Note that this will not produce good results for the C27 trimmers.since
both these trimmers are not connected to ground - that does require an
insulated tool when adjusting either of those capacitors.
