Maybe I'm messing up somewhere in the color AFC procedure. The darned thing feels like it's so close to locking . . . .

There are 10 (maybe 12 with vertical retrace) color bands, meaning the oscillator frequency is off by 600 -720 Hz. So either the oscillator frequency is tuned this far off and the AFC can't pull it in, or there is something wrong with the phase detector [edit - or the reactance tube circuit] that is forcing it off to one side.
