Folks, I am at page 42 in the manual, doing resistance checks, and I find that some are off, specifically : U4 pin 5 2.8 K U4 pin 8 1.4 K U6 pin 1 7.6 K Any ideas or suggestions before I proceed? I note that I am missing C2 and C4 (they are on their way to me), in case that would influence the readings. Thanks Dave, W5SV
