I've started working on this design. A lot of the Audio equipment on your OSE wiki page is going to need a +- supply, so I thought that it would make sense to first design that. So here it is: . Here is the basic schematic I'd follow: (scroll down to Summing Amplifier Audio Mixer). I'll probably use these potentiometers for volume control . And I'll use screw terminals for the output. That way you can connect to what ever type of connector you want on the enclosure.
