[Elecraft] K2 control board

[wsm at amaonline.com]

Hi
I've been trouble shooting the control board and front panel of my
K2 # 5846. I see an empty place for capicator C44 below the left end
of U6, the microprocessor.
This capicator is not mentioned anywhere in the instructions on 
the control board and is not in the inventroy for the control board.
I would like to know if anyone has a capacitor in this location, and
if so , the make and model?
Thanks
