All right, yo. I found this schematic:

I'll be doing a layout for this one, but I can't read russian. Any of you guys to translate this stuff?

Also, I see that this schematic is not all without the electronic switching. I wonder if I can get rid of some of the transistors.

Useful information:

1. All "1/2 U" points are connected.
2. All POTs are digital, made by Texas Instruments.
3. PIC MCU are not shown on schematics. FETs and Digital POTS are controled by PIC MCU.
4. DA1-DA3 chips power supply is: 11pin - "+U", 4pin - "ground point".

Hope it helps somehow
