I passed out cold watching Big Bang Theory last night on a Motorola Cadet.
The set worked when I got it, so I figured I'd let it run out to see how it did.
Turned it on the other night, fell asleep for about 45 mins, woke up, and the picture wasn't filled out completely on the right side. Let it cool down, fired it up, still not filled out. Put in a new 33GY7 yesterday, turned the set on about 8:30, looked great, fell asleep, woke up at 10:30, picture still looked great, turned set off, went to bed
Now mind you I wouldn't want to fall asleep watching just any vintage TV, but I have 3 Cadets that I have a total of $15 into, so if a part fails or something happens so be it, one of the sets is a parts set anyway.....
