I too remember a fair amount of late '80's-early '90's Zenith tubes being bad; but, the problem really took off around '93. Really, here are my experiences with Zenith CRT's:
1. Delta gun tubes from the '70's almost never went bad. Even to this day, they are still very watchable.
2. The first inline tri-pot tubes used with the system 3 chassis were not as good. The 13", 17", and 19" held up pretty good but I've seen plenty of weak 23"/25" ones.
3. Same story on the COTY (?) tubes from the early '80's thru the early '90's.
4. And, we already know about the early '90's and up.
