Well not quite...

The 78L05 is a 5V regulator and is what is required for U8

U2 is a 78L06 as I believe is a 77L06. They are both 6V regulators.

I suspect you have fitted the 78L05 in the U2 position as the numbers 
are quite small and easy to confuse. The 77L06 may be a replacement 
for the 78L06, it is most definitely not a replacement for 78L05 and 
you will damage your K2 if you get them wrong.
