Gentlemen:
It was an easy fix. Being that the receiver was correctly electrically AND mechanically aligned I wondered how it could be that the 10 turn stop would be out of adjustment.

Somehow during the last move, the stop pin jumped over the top of the stack and caused the drive to stop 1 turn too soon. This allowed it to tune lower than would normally be the case (and short on top of the band). By GENTLY prying the stack apart from the stop disk (and rotating the kc change knob) so that the pin would clear the stack, it returned to being in alignment.

Spent a bunch of time staring at it and using the mark 1 mod 1 cranium filling. I love easy fixes. Since it's apart, I think I'll work on another one I have. Want to swap IF decks on my 1347 and see if that fixes an agc problem on the other receiver. 

Sayre is near Towanda. About half an hour drive.
