I had a request to build a few of these years ago and then someone wanted one about two weeks ago, so I built one for him. I didn't get around to building one for myself but after hearing the latest build i just had to make one for myself. I uses an internal voltage converter (a TEC 2-0923) to convert a 9 volt power supply with the necessary +&- 15 volts for the circuit.
here's some pics of the latest build:
