Marc,
Please check the placement of those trimmer caps. If you follow the old
parts list, it is easy to swap C21 and C23 with C44 and C46. If this is
a recent kit, C44 and C46 should be red. While the others will be brown.
I just serviced one here that had the same issue and those trimmer caps
were swapped.

This is my 2nd K2 build this year. This fantastic kit has kept me sane. I
tested every component on an LCR meter (found RFC10 open) and tried to work
as slowly as possible.
I got to the end of the build to the very last alignment step.--
The adjustment of C44 and C46 for the 12 meter band and I can only get
0.2W. 10 meters is fine with adjusting L12 and L13 but 12 meters (which I
do not use but it should work) is nada.
I had the exact same problem on 20meters but careful tweaking of C21/23 and
L8/9 and it burst into life.
When testing the capacitors I noticed they had quite a wide tolerance
range. Could the band pass range for the 10 and 12 meter bands be too high?
Any ideas would be appreciated. I am quite good at wondering down rabbit
holes.
