I have made up the control board for my K2 and all looks good. The resistance
checks were all within specs except the U5 OUT to gnd which was about 3600
ohms. Checking further I find the 8R and 8T voltages seem OK but some 5 volt
areas are not. For instance the 0 volts and 5 volts on U7 pins 5&6 are
reversed as well as U6 pins 24&25, U8 pins 10 & 11. Someone probably has the
answer right at their finger tips but I cant see what the problem is.
