“Moog Opus 3 keyboard circa 1980.
I have had this keyboard for about 30 years for most of that time in an attic.
There are a few sliders missing but these are available.
The D# makes a slightly weird and same note for each octave. I have read this is common problem that can be sorted.
The right hand side panel is loose and needs to be properly fixed together with a small block beside the rightmost key.
It does work and you can get some great sounds out of it.” Click here to visit listing on eBay
