Epilog
I aligned the T8-14 late this afternoon using my "new" (to me) B+K - Precision 4040 function generator. In all, it took about 45 minutes. I went over the AM band multiple times since the low end was so far off. And then on band C, I had some trouble finding the fundamental at 18 mc but I finally did so after some tweaking and aligned it properly at 18 mc per the instructions.
I already knew the AM band's alignment was WAY off on the low end of the band. Alignment benefited the IF chain as well as all three bands.
I spent some time listening on all three bands, then stopped for dinner. Afterwards, I put the chassis back in its cabinet and shot the following video. You will notice now that not only are stations coming in close if not right on where they should be, but the low end of the AM band is now just as loud as the high end. And that is how it should be.

And...that is it for this RCA Victor T8-14. The chassis is complete, aligned, and plays very well on all three bands.
