Broken PolySix

[Andrew Puls Q-Bot Eye]

I found a Korg PolySix at a thrift store this weekend, and it is not
fully functional. The presets on it (at least some of them) seemed to
work (although the "2" and"4" lights would not turn off), but trying
to edit the sounds did not work. The envelope generator seemed to be
stuck in a very long attack and very long decay mode and turning the
knobs did nothing to change this.Putting it in gate mode, however,
worked fine. The octave switch worked sort of (the 4' and 8' were
diferent but the 4' and the 16' were the same). The arpegigator worked
perfectly allong with the pitch and modulation wheels, the
keyboard,and the effects section (though the rate/intensity knob and
the delay knob didn't work, (I don't think so at least))

My point in telling you all this is that this thing is $80 and I was
wondering if it seems worthwhile to pick it up to try to fix it. (Are
the parts for this synth available, is it a simple problem, what kind
of problem do you suppose it is, etc... If it is not a simple problem,
how cheaply could I have someone else fix it?)
