Tom,
On my latest K2 build, I put a 1pf cap into the C68 (10pf) location. The 1pf cap was labelled "1D", which looked a lot like a "10" to my eyes. I think it took me about 4 hours to figure that one out. Once fixed, it all fell into place, and everything worked.
We all do it!
73, Jim KO5V

Don Et Al,
So, It is with some embarrassment, and much relief, that I can report it
was operator error and my BFO is now working perfectly.
I got home from work and was getting ready to do some continuity checks to
all the circuits surrounding and including U11, but decided I better check
all the components again in that section with the RF board disconnected and
out of the case.
I found much to my chagrin I had not installed D37 and D38! I had them
checked off in the manual as being installed, and I even wrote in pencil in
the margin on the next step where you put the rest of the V149's in the RF
board that I had 2 left over, but I failed to notice I had them left over
because I did not put them in the step before!, good grief.
Anyway I have a high BFO reading of 4917.60 and a low reading of 4911.98
with a difference of 5.62.
Thank you Don and to others that gave suggestions, and I do wish those
having similar problems well in their trouble shooting.
Upward and onward 73,
Tom Bewick, K2BEW"
