Oberheim OBSX vintage analogue synthesizer SN 913107

via this auction

"Amazing six voice analogue poly synth. Big CEM sound! Basically like a cross between an OBX and an OBXa. Great overall shape with some scratches and scuffs here and there. But super clean overall. Sound is amazing. Get one of these and have yourself an OBXa for half the price. If you search there is a midi interface for this being sold out of Germany.

May need slight adjusting, one filter seems slightly too bright to my ears, easy adjustment with internal trimmers.

Looks like it has some foam rash on the back of it. Could be cleaned off easily. All keys work.
Have not tried CV/Gate, but have no reason to believe they wouldnt work. This is set up for the full 56 programs, but it needs one eprom to fill it out. All chips are there."
