First time kit builder and have just completed control board, but  
resistance checks do not seem to check out for several points:

P2, U5, U4 are all okay
*Q1 & Q2 collectors - both around 29K
U6 - pin 8 is okay (about 75K),
*U6 - pins 13, 14, are around 40K,
U6 - pins 29 and 30 are okay (around 40K)
*U8 - pin 2 about 40.7K, pins 15, 16, both 29.3K

I have inspected all solder joints with magnifier. I double checked  
components.

What should I do next?
