[Elecraft] TP2

[Peter]

Hi

I have a K2 rig here for repair and this baby has a instable frequentie reading on TP2
Afther touching a part of the bfo its solid (4,917 mc)
Q24 is working good, but on  U11 (bfo) pin 6 and 7 are 1 volt too low.
I a have all ready replace D37 and D38 bun no effect.

Question. Why are there 2 cristals? (X3 and X4)
The low voltage on  pin6 and 7 of U11 is this caused by a defect IC or something else?
