Marinos,
You may want to check the soldering of all associated components - look on
the K2 Control Board schematic lower left corner to identify the components
in question.
Actually the 3.78 volts may be close enough. The real test is when you
finish the K2 and if you do the advanced AGC refinement check -- you should
notice no change in audio level when switching the AGC on/off when there is
no signal at the K2 input.
For now, it is probably OK to ignore the 0.02 volt difference. That small
an error may even be attributed to your DMM.

1) During the AGC threshold adjustment (control board) the instructions call
for adjustment of the potentiometer R1 until the voltage at the lead# 5 of
U2 reaches 3.80V. In my case, the voltage can go to a max value of 3.78V
with the R1 being fully counterclockwise.
Since the difference is only .2V from the required value, I do not really
know if this finding has any importance or needs to be addressed.
Any advice would be greatly appreciated.
