Looking for Zenith Substitution Part Chart

[zeno]

The board you have is a 9-69 IIRC not 9-27X
The "new" 9-27 was probably used & the old 9-69
went in the box for core credit. It never did.

CAVIAT EMPTOR !!!
Zenith OEM modules were sold to dealers at Suggested
list price. If a board costs you $25 you sold it for $25.
When you returned the dud you may get an $8 credit,
that is your profit on the part.

Normally you write "dud" on the box & it either goes back or
get repaired when it was slow. So when buying modules
its very hard to be sure what you are getting. The E-bay
ads mostly show it isnt the old TV man selling them
but some one with no knowledge.
Small Zenith modules will be neatly wrapped in tissue paper.
But thats not the last word, it may have been tried then swapped
back out. It may also be an unmarked dud if the paper is
missing or messy.

Okay, so which is the most recent version? I do like it because it isn't in a metal housing like the 27. My SM says that the module used is a 9-27 with the 9-69 being an alternate. The one I have installed is the 9-69. I guess I got confused as it's been a year. It was new and wrapped in tissue paper, so I'm assuming it is new. I took the 9-27 and put it in that box for storage.

Odds are the 9-69 is the latter module ( higher part ## ).
Why it seemed to come up randomly & never took
over is beyond me. The 9-27 goes back to the first
4 tube hybrid ( B line) through the last hybrids in F-line.
9-69's seemed to pop up randomly but they may have
been used on specific runs for unknown reasons. or
use was stopped for unknown reasons.
