Progress report, or lack thereof:
During the summer Mike (Morzh) kindly gave my Sencore AM-FM alignment generator a good going over, so I set the long-neglected 440-T on the bench this past week and gave the IF section a complete alignment. (Yes, I now have a set of plastic alignment tools.)
I do not have a good schematic matching the 440-T's multiplex decoder so I am sort of stuck on that. It is difficult to check voltages and double-check the large multi-resistor unit in the middle of the multiplex board without the proper schematic.
So, this one went back on the shelf...I should probably pull it back down and give it a good RF alignment next, to get into practice with these solid-state FM receivers, now that I have a good generator (with thanks again to Morzh).
