Nope. Didn't miss any caps. Especially not on the DA board. It's a tiny board that was mostly surface mount caps. Took em all off and all the through hole caps as well.

As I said in my last post, the Vertical is working now, unless you think the Vertical output IC could have an effect on the Pin Amp circuit on the DA board?

I did replace the Vertical IC with an NOS part, so there could be something wrong with the new one, but I don't think it's specifically handling the East West stuff, that's on the DA board.

It's using a TEA2031A for the geometry adjustments, and when I spray the thing with cold spray it gets wiggly and it looks like it's pulling the sides in. So I'm suspecting that one. I can get it cheap so I just got one coming regardless.

Attached is the datasheet
