Wow - that sure is a lot of capacitors! And nicely layered too....
I'm afraid it's only those two pages in the service manual - Zenith doesn't seem to provide under-chassis diagrams for the models (at least of that era).
I checked Riders and Beitman's too - but those are just schematics too. That being said I think the schematic from Beitman's might be a bit clearer - attaching that too in case that's useful.
