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.

I replaced the screen shot on the last page. The new one still doesn't do it justice, but gives a far better impression of the color gamut.
If you look closely the picture curves downward at the top and there's a bit of wave near the bottom. Could the sync separator be causing that?
Easier access to older TVs, parts... well, just about anything older is one of the things I like best about the internet.
