KPA100 trimmer flat side

[Tom Zeltwanger]

I am working on my KPA100 and installing the three plastic trimmer capacitors.
Instructions say align the flat side with the flat side on the silkscreen.
Unfortunately both ends of the trimmers are flat. I saw this discussed before
but just want to confirm that I should align the "long" flat side with the mark,
and not the short one. My guess from the silkscreen was just the opposite.

Thanks,

Tom KG3V

Tom,

I figure you have the blue plastic body trimmer caps there.

I do not have one here to check which end is which, but you can check
whatever you have in hand easily with an ohmmeter.

Check for continuity between the adjustment slot to each of the capacitor
leads.  Call the one that indicates continuity GROUND - align that ground
side toward the ROUNDED side of the board silkscreen outline.

Don,  Thanks. I hope they either stopped using these or changed the
instructions. That said, this is the only ambiguous thing I have seen in all my
work so far on the K2 and KPA100. That's quite an accomplishment.

Oh - I just realized maybe I installed them wrong in the k2. I'm not going to
change it now unless I have a problem.
