Circuit Overview:
     A monophonic reworking of the Jupiter 4 basically with some added goodies.

Service Tips:
     Anyone? Lots of similarities to JP4 obviously so cleaning issues on key switches (carefully scaling with an appropriate dental pic, etc. is often one way to remove tough residues).

Parts:
Roland still stocks many parts for older instruments! You can always order them through your local Service Center and see what happens! Otherwise I have some parts also so don't hesitate to ask.
