You had mentioned that the "...AVC voltage seems to be tracking along with tuning" so I assumed the problem was with the adjustment of the meter itself. What is the voltage difference on the AVC line between a strong station and no station?
My next guess would a weak tube somewhere between the RF and 2nd IF tubes. Have the tubes been tested? Even if you have and they test OK, it may be worth swapping out a few tubes in there to see if you get any better response out of the meter.
