Chuck,
WHAT?? Did you have 4 ceramic trimmers with red dots on the side? The
same as that used for C22 on the Control Board? Those normally will not
work for the 12 meter bandpass at C44 and C46.
The large yellow plastic trimmers should go at C32 and C34, and the
ceramic trimmers with the red dot should be at C21 and C23.
There is not a great deal of difference between the ceramic trimmers
with the red dots and the plastic trimmers with the yellow bodies, but
in extreme cases, the difference is enough to cause a problem tuning 14
MHz and 18MHz.
You should have had 2 red bodied trimmers similar to the ones with the
yellow body, and those would go into the C44 and C46 positions.
If the trimmer capacitor selection has been changed, then the K2 errata
page must change to keep up with it, and it apparently has not.
I will contact the K2 product manager to see what is going on.

Bob, Don,
I just finished up a K2 as well. The trimmers I got didn't match the
description in either the manual or errata, so I wasn't sure what I
was looking at.
I had to use clip leads from my cap meter and got too much stray stuff
going on to accurately measure min and max.
I talked to Gary in Watsonville. Here's what we summized. The larger
bodied yellow trimmers went into c21 and c23. The remaining 4 smaller
bodied white with red band trimmers went into c32, c34, c44 and c46.
It works. I get good output on all bands.
Don't know if this helps or not.
