ART Tube Opto 8 Schematic

I didn't get any replies to my request for a schematic for the Tube Opto 8....so I made a schematic myself. Its not a complete schematic. There are 8 channels, and I only diagrammed 2 of them, one with an Instrument Input (CH 1) and one of the regular channels (CH3). I didn't diagram the digital circuits either....I was just interested in the analog signal path.

The plates are operating at about 25V. Other voltages are pretty much as one would expect.

Enjoy!
