Yep that chassis had two chips that was discontinued. 1 for color and the other was for sync separator/osc ic for vert and horz. I had plenty of the color but no sync chip. When the sync chip would go out the picture would look it was scrambled like the old pay cable stations would look.

Thank you Jon take your time, but that's it so from what I see so far. Man that's a great set pop a zenith tube in and the picture will blow you away. We if had the internet back in the day hard to find parts would be easier find. If I remember right I had a that Sylvania had a rat tuning set that was really nice cabinet I waited years to run across some chips but I scraped.
Think Atari 2600 would be ok I think it was Nintendo's was not good to some sets. I think that was because the rapid sync and color changes would over tax the ics and make the chips run hot and then go out.
