The last main daily watcher TV set we bought was in early 1983, a 25" Zenith System 3 made in December of 1982. Still in use as we speak, got local Pittsburgh news on as I type this. We had it serviced in 1999, back then, our repairman said the CRT is showing it's age a little but the picture is still good. I remember every once in a great while, it did have a little bit of a red screen , I remember posting here about it but except for those few times, it behaves quite well and hasn't done it for a couple of months.
All I can say is "from my keyboard to God's monitor" but I'll keep praying, I love this set, been watching it since my sophomore year in high school and will be celebrating it's 23rd birthday this year. I look on the back and is says, "Zenith Radio Corporation."
