[sdiy] +/- 9v synth circuits

[Ray Wilson]

Hi

The Sound Lab mini-synth may give you some low current ideas. The whole
thing will draw less than 6 to 10 mA when completed.

I'm in the process of building one but all of the circuits shown have been
bread-boarded. I will post the final information when the unit is
completed.
