The short answer is: I don't know, but I do know it's possible.


I do not have any schematics for the solo board. There used to be some out on the internet, but I haven't searched in a while--maybe you can find them?


If you can find the pinout of the D-sub connector, it should be safe to power both voltage rails (and ground) and that should get the preamps working. You will need tech skills and a clean power supply, and there are no guarantees.
