[Elecraft] voltages

[Earl]

Hello.
In checking voltages in my K2, I find that the voltages on U8 pins 10& 11 are reversed.  Therefore the U7 pins 5 & 6 are reversed.  I get 5 v  where I should see 0 v.  Also on pin 24 U6 i measure 0volt unless I have the CAL FCTR mode  activated.  I think I had this problem once before but cant locate any notes on it.  
I wonder if anyone else has had this problem or can offer any suggestion.
Thank you de Earl
