Wouldn’t that cause smearing in the black and white picture, and/or the color and luma signal not being aligned. I don’t see smearing in the BW picture, and the color signal is not shifted to the right of the BW signal. It seems aligned with luma but is heavily smearing.
I think another clue is that the color burst has smearing, and the color burst doesn’t pass through the chroma bandpass. The smearing of color burst is causing the tint control to have a small range, but after aligning the chroma AFC, the color oscillator is still able to lock instantly and without issue.
These clues seem to suggest it is not delay line and not chroma bandpass. It is RF or IF that is not peaking enough at 3.58mhz.
