Hahaha
I think I should put on my "cheater" glasses a bit more often @Wasnex
Hmmmm?
I guess the amp I have was modded at some point!(?)
Yes looks like (hehe now that I put on my readers) you provided me with EXACTLY what I needed to help whomever I've chosen (from the WONDERFUL list provided by the collective!!!!!!!! Ty, all) to get this fun piece of decor making sound again!
I think it may be stock.
I found images of at least 2 amps with this I/O.
Also, I don't think the knobs on the example in post 15 are OEM. Adding volume and tone are probably a common mod.
There's another schematic of the Compact Projector that shows an amp circuit with controls. https://www.paulivester.com/films/projector/amprosch.pdf
