Known issues:
Some of the coloured knob caps are missing (see photo).
The filter cutoff knob can be slightly crackly and probably needs a clean with some contact cleanser (I've still been using it happily as it's not that bad).
The octave switch knob is a little loose and sometimes slides past the markings. When it does that I just slide it back - it still works fine even when switching octaves mid-performance. The pot probably just needs to be tightened up.
For me, none of the above issues have prevented me having fun with this synth - it's to be expected for a synth that was produced between 1978 - 1982!
