Yes unipolar supply. Pull from the +12V rail. It is a bit power hungry. I have not taken actual meter reading's, but it has to be over 500mA. Here is a shot from behind the panel. Adding the ten turn pot was a bit of a challenge as you can see. I had to move the cap for the -9V rail and flip it to the other side. the two trim pots below the power connector are for the +/- octave switch. Essentially giving you the ability to trim both. The additional TL074 is to boost up the outs and also for voltage followers for the raw pulse and saw outs. The trimpots under the IC are for adjusting amp levels for the main outs. Power protection diodes and yeah of course you need to saw off the keyboard.
Here is one of the spare rosewood button switch caps. This was an extra one.
Details on the panel. The entire panel was made in house. I have full CNC metal capabilities as well as a full screen-printing facility in my basement. The total size is 45hp with the traditional bent flanges on the sides. I went for the original authentic look. Without those you could save 1hp and it would be 44hp. I have vector drawings of the art and panel that I am more than willing to share. I could do a run of these, but I would need a minimum of 10 pieces in order to make it worth the time. I did not powder coat the black. I used a two part black epoxy ink and added a lot of flattening powder. It can stand some abuse, but not as much as powder coat. If you know of any MU guys, you can hear it from them first hand that sometimes their panels cost more than the electronics. And for good reason. There is a lot of love in these panels.
If after all of this you guys are not scared off I can take pics of the keyboard and show you EXACTLY how and where to do surgery. Takes a bit of guts to cut into a Moog junior doctors, but with a little direction it is easy to do. Learned a lot of by doing this too. FYI these are four layer PCB's! Two ground planes. That is part of the secret for such a low noise floor. Special attention has to be given to the cut after you make it. I can go into more detail, but I have a feeling I will be hearing crickets after this post, but maybe not.
