If SAMS tells you how they are to be set, do that, but if not, vary them and see if you can get the specified reading at some setting. For example, if the video detector output p-p is wrong, is it because of AGC adjustment?

Right now, the only adjustment that I think would have any effect resistance wise of pin 7 of the 1st video amp would be the R22 pot, sound reject, but I have no reason to touch it at this point, so I guess I will ignore the high ohm reading for now.
