Circuit Overview:
     More complex options than other Junos with three dco's/voice but sterile sound quality compared to earlier Juno units. Juno-2 has 61 keys instead of 49 and adds some more things I believe but very similar machines.

Service Tips:
     Not aware of particular issues in these.

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.
