Roland Juno 106 chorus input+ speed mod and repair

Posted by in equipment, mods & repairs, Studio

This one was suffering from juno cancer on one voice. Uncoating the 80017 chip did partially not work (no resonance). Put a replacement chip on a socket and recalibrated all of the 6 voices. Took 2-3h

  
    
   For the chorus there was used a test-point on the board as input and a new pot was installed for chorus speed. Very useful! 1-2h
