Bob,
You have too much capacitance at C32 and C34.
Contact Elecraft support and ask them to send 2 trimmer caps to replace
C44 and C46. The ones you have with your kit do not have a small enough
minimum capacitance. The p/n you need is E540011 and the bodies were
red the last time I saw them.
The 35 to 70pF range you measured is higher than I would expect. They
should measure about 20pF to 45pF.
If you have a similar problem with the maximum power on 18 MHz as well,
ask for replacements for C32 and C34. The part number is E540002 and
they have yellow bodies.
See the latest Errata page - download it from the Elecraft website.
Trimmer capacitors have become a problem for Elecraft over the past 6
months or so. I believe you have brown body trimmers at C32, C34, C44
and C46. Several of those were found not to meet the manufacturer's
specs for capacitance range and were dropped.

Finished my K2 in the last few days and really enjoyed the build. It was
just like old times.
All bands except 12m have aligned OK...but I cannot get any more than .5W
output on 12m - no matter the C44/46 trimmer cap settings or the power
setting. And while it not fun, I pulled components C42,C43,C44,C45,C46,C47
and C48 and they all showed fine on the cap tester. C32 and C34 are
adjustable from about 35pf to 70pf.
