[Elecraft] K1 capacitor ID help

[dean at jonemail.com]

Hi all,
I am installing trimmer caps C13 and C20 on the RF board and having
trouble identifing which way they need to be installed. They are
physically different than the discription in the manual. There is NO
flattened side to them. They look like a round body that has a square
tab extending on one side. Is this square tab the equivalent of the
flattened end? Thanks for any help.
