My K2 PLL problems all originated in one inadequately tinned toroid wire. I have successfully built a fair number of kits with toroids, but it is pretty easy to end up with a lead that is not actually connected. Even though it looks good.

So that is where I would start, check for continuity on every single toroid.

having repaired my PLL problem with a great deal of help and advice from 
Dave at tech support, Elecraft i moved onto the next set of tests which 
was the bfo frequencies, on selecting CAL, Counter i get a reading of 
4.9136, on pressing either the band up or down all i get is zero's.
Fitted crystals are 4.91s in X3 and X4 positions
Have checked all the details in the trouble shooting paragraph, i can 
find no fault with any of the components, all values and positions are 
correct.
I have to add that this was purchased as a non-runner.
Any advice appreciated
