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.
