Apart from the schematic that you provided in post #1, do you have any other documentation? I ask because I could probably send you a pdf of the manual/assembly guide for the V-7AU that I have. As I said, these Heathkit VTVMs use largely the same circuit, with only minor cosmetic and/or circuit differences, so it might be helpful for set-up/calibration.
