Should i bother restoring a zenith?

Also, I got a chance to evaluate types of capacitors on this (for my collection) newer set. I wanted to see what I might immediately want to remove as far as commonly known to fail types like bumble bees for instance. I didn't see any of those. Mostly I saw the old reddish brown drops which I hear are ok in most cases. The paper-foil is what I think needs to go and what I saw was several black plastic coated paper caps. I wonder if these are as bad as the bumblebee type, or even remotely as bad.

I think for now I will leave the multi-section cans alone as they are pretty tough old parts and sometimes I think they might be better than what you get from China. Anyway, what about those black beauties?
