Well, although not 100% perfect, I do have this shadow meter working now. I replaced 6 resistors in and around the IFs and Detector  circuits which seems to have increased the AVC voltage some. I am now getting -0.5volts off tune and up to -4.0 volts when tuned to a station. I also took the meter assembly back apart and worked with the magnet some (seems kind of weak) and put back together and adjusted the light some as well. So now getting movement as station is tuned in and out. I also have found that putting a small magnet near the shadow meter increases the movement some.
I am now ready to quit while I'm ahead with this one and move on to the Code 125 version and see what I can find there.
Thanks to all here who helped,

Frank
