Another question:

While at it, I disconnected few caps and measured them (they look really good). All of them so far right on the money. Well within tolerance. I am not sure I want to change them (let alone this being a real pain in the Zenith - very tight assembly and rubber wires). And there is a lot of them too.

Anyone has a good luck with not really throwing the caps out?

Also interesting, the electrolytic cap (4 caps assembly) looks good too. 40uF measure at 56uF, 20uf - at 28uF, 200uF - at 400uF (well, yeah, this one is a bit out there, but then the voltage is low - it is a 10V rated cap).

Up to you. Ya got time bombs. If you want the set to play 20 years from now, change 'em all. If you don't care, just listen with pleasure.
