[Elecraft] [K2] Control board U4 8v regulator issue

[Mike-WE0H]

Has anyone else had a 8v regulator (U4) on their control board show a 
lower voltage than it should? Mine shows 7.61v with the board in the 
radio or on the bench with a 14v supply connected to the input of that 
regulator. All components and soldering look correct. The 5v regulator 
is at 5.00v. All functions in the test procedure work as they should 
except the AGC voltage couldn't be set to 3.80v because of the 8v buss 
being at 7.61v, the AGC voltage changed as it should but was lower than 
the 3.80v suggested for setting R1 to.

Nothing runs hot or smells hot. What do you guys think? Bad regulator or???

Many thanks,
Mike
