just came across a memorymoog autotune kit from the early '80s. part number 997-044667-101 Anyone have info?
I wouldn’t use this kit cause the resistors for the DMUX board are wrong calculated 
Used to own a fully loaded plus version,maybe 3 extra boards were fitted , as well as the sequencer/midi board,contact lintronics in Germany,Rudi will definately know (pretty stable with the slight detune swirl done for you! massive sound!
