Bob,
In "Admiral 24C16 restoration part 5 (we have sound!)" at 3:30, you adjust a coil on the tuner which fixes the audio problem. Specifically, it adjusts the output IF frequency of the audio band to properly go through the audio IF stage which you just aligned. You do not re-adjust the fine tuning of the station and presumably the video remains clear (the video IF strip still gets what it needs from the tuner output, frequency-wise).
How can this be without two mixers in the tuner? See my previous post about two mixers.
