There are normally only two coils to trim, one to balance the AFC discriminator and one for the intercarrier sound, neither really need anything more than a good signal to adjust.
What is the actual fault? Sorting this out is probably much easier than trying to lash things up to work around it.

The problem is with strong colours, they're grainy as hell with colour noise, coloured text or subtitles looks pretty bad. Colour bars show it up well, the noise/dot crawl between each colour bar.
There is the 4.43MHz chroma trap (L6) which I have adjusted for minimum patterning, but minimum is still not good.
