Electronotes is well known as one of the main source of information on analog synth and circuit design since 1972. Schematics and design notes are still available from

This synth includes 1 DC coupled mixer, 1 VCF, 2 envelope generators, 1 VCA, 1 sample hold, 3 VCOs, 1 keyboard interface, 1 noise/random voltage, 1 white noise, 1 power supply. The power supply is heavy duty with +15, -15, +5 volts, and ground. It has patch points for powering external modules as well. The oscillators and keyboard work on 1volt per octave so this is compatible with many different types of modules and brands."
