Does anyone know anything about this Zenith set?

Of course The hor. efficiency coil was a standard circuit component ubiquitous to other brands besides Zenith. Zenith was the only one using the notorious plastic coil forms (AFAIK).

...The crumbly plastic as noted above (thanks for the warning, Tim) is an age issue as much as heat issue.

Correct. It's seen most frequently in old roundies and 19" metal cabinet table models with marginal cooling. And in very high hours sets.
But upon acquiring any Zenith tube color set, the very first thing to check is the H efficiency coil to be sure it's intact. If it's come apart, you can't run the set without burning up the H output tube. Hence the earlier ("burst aortic aneurysm" metaphor).

A discussion here (the OP used the term "H. Oscillator tube", meaning to say "H. Output tube")...
