Sound and video not tuning together with digital converter: 1956 philco 21"

[old_tv_nut]

If the sound and picture don't tune at the same point, it should be obvious that it's not the tuner, which has no independent adjustment for the two (unless it has an internal sound trap adjustment, which I doubt). It has to be something in the IF (like the sound trap / sound takeoff) or sound section alignment.
