Help Identifiying Vintage ADM console strip

[mrvision]

Does anyone have an idea what type of ADM strip module is this? It seems like a very early model...
Schematic or any advice about racking and sound will be also very appeciated!

Looks like an early version of the 770 module before they had the multi-color knobs.

Yeah I also thought it looks like an early version of an ADM 770 or maybe an earlier module before the well known 770.

I also fund this picture in gearslutz and the custom summing box made here has the same modules still no model number on it...

Interesting, its turning into a mistery now...

If you PM me your email address I can send a PDF of the 770 schematic.  Too big for the files section.

Hello!
I'm looking for the ADM770 schematic. I have one but it's very bad quality. Do you have this readily available?
Thank you,
Pete

This picture is of an early 700 series module. It is VERY different from the 770 series. I believe the 700 series was a single supply system whereas the 770 went to bipolar (+/-20VDC) supplies (as did all susbsequent designs).

The only schematic I ever saw for the 770 module is the one that is on the technical docs section of this forum:

Quality is not great so probably that's the same one that you have

I searched my archives and I found a 770 document (not schematic) that is has some more info:
