Ampeg Echo Jet (schematics in your basement?)

Anyone have one of these. I have one stacked under 10 years of flotsam in ISO 2 at the studio that needs a fixin', but I can't find any schematics that even sort of look like it (to my trained like a circus animal eye) Oook.

A guy took it a couple years ago and really messed it up, just like the other guy. I think it's my next project.

Even if I can't get schematics, I will post pictures here. I am sure everyone has an idea!

Which year?
Which Version?

I know of 6 possibly 7 alterations to that circuit.

Awesome! I will have to look, but any version is better than none at all. It's been boogered by the best. (worst!)

It's about right by date. 1960.. I can't remember any revision numbers from the charts in there.

Thanks! Looks like I need to signup for another cool web resource!
