Hey, Why not just build a power source! Most books on building synths have the schematics and parts. _Build a Better Music Synthesizer_ by Thomas Henry has a nice +15V, -15V, +5V source. You can buy a small 36V transformer from Jameco (http://www.jameco.com/) for under 10 dollars! Steve Varner svarner at sdcoe.k12.ca.us
