Hello all,
I was lucky enough to stumble across an old Bass Micro Synth while helping my friend clean out some storage space in the back of his music venue. I took it apart and looked it over and it seems to be in good shape, but I didnt find a power supply. It looks like an older pedal, it is in an all metal trapezoid enclosure. I says bass micro synthesizer in emerald green and the silk screening is mostly black with white lettering and the metal underneath showing through in the spaces between.

What I need to know specifically is what the power supply specs would be or where I could find them so that I can either build or buy one depending on how hard they are to find. I would like to attach a picture, but I cant get the file size small enough.
I appreciate any help you guys can give me. Thank you,

Jud
