Just figured out why the voltages were so different. I was measuring at pin 5 of U2 rather than pin 1. Stupid, stupid, stupid. Well, that seems to be the only way I really learn. Make a mistake and correct it. And just when I was beginning to think I was understanding this AGC thing. :-) I'm off to work now, but, will remeasure the voltages and post the results as soon as I can.
