Looking for Zenith Substitution Part Chart

[jstout66]

I'm looking in my Zenith Sub book.
A 9-83 has NO sub
A 9-27 will sub with a 9-27X or a 9-69.
What does your schematic show as the correct module for this set?
IIRC your set is a flat chassis.

The SM has the 9-27 as the installed module with the 9-69 as an "alternate" module. Don't know if that meant the set was supposed have been made with the 9-27 and occasionally with the 9-69.

Does color of the board mean anything? I notice that some boards are you basic brown and others are white and green. Is that something that denotes age? Seems the brown would be older than the colorful white and green.

This is the only substitution sheet I have. I don't know if it's complete.

Here's the CRSP pages for the mentioned modules. The 9-83 is an orphan - used on only a few chassis, and no upgrade/replacement.
