Korg 770 schemos

[Duane R Balvage]

       Hello again -


        Sorry to butt in aagain, but I am looking for the schematics 

     to a smallish 70's monosynth called the KORG/UNIVOX 770. The 

     case was thrashed on it, so I gutted it to put the circuitry

     and a PAIA MIDI2CV8 box, along with enhancement circuitry into

     a rack box. The reason I need the schematic is because I am 

     adding ADSR envelopes, a second LFO, a second LPF (diode ladder),

     a second VCA, Pulse and PWM on oscillator 2 (currently only does

     sawtooth and ring mod and noise of different flavors.), also

     adding a sub oscillator on oscillator 2 (it only goes down to 16'

     octave - oscillator 1 goes down to 32' (!) and 64' (!!!) )

     Soooo ... if anyone has any info, it would be greatly appreciated!



                            Thanks Again!


                                        Duane
