After going through the other alignment steps here is what the Video Amp test point U with the color level set at the half-way point, it looks better than before.
Also here are some videos (note they should open in Imgur, let me know if they don't work)
- Adjusting the B&K 425 signal down to zero and then back to max, curious if more B&K 415 gain would prove a better response curve: https://imgur.com/jmoT9J0
- Color level starting at the minimum and then turning the potentiometer to the maximum: https://imgur.com/5RBpapN
- Adjusting L19 (2nd color amp) which should be adjusted for minimum 3.58mc response. I starting with the slug at the top and turned it down to the bottom: https://imgur.com/lVtZ9qK
