I work on anything I can lay hands on from 1928 Atwater Kents to 70's SS Zenth TV's, and newer stuff if I have a manual and reason that are both good enough to make me bother.
The reliable plastic types started in the late 50's ~1957/58 and gradually phased out the paper based caps over the next ~5 years (some makers jumped on 'em others lagged badly).
