"Polymoog Synthesizer Model 203A, complete with Polypedal Controller and original metal legs.
This one is of the latest generation of Polymoogs, serial number 3795. It actually bears the name Polymoog Synthesizer on the front (instead of Polymoog Keyboard).
This machine has been overhauled extensively. The overhaul includes:
Repairs: this Polymoog has been fixed. It is one of the few around that are 100% functional.
All the capacitors on the power supply have been replaced with new ones in order to reduce chances of burn out.
All eighteen opamp IC’s LM3080AN on the top left and top right circuit boards have been replaced by their modern day equivalent NTE 996. The old LM3080AN is a common cause of failure in polymoogs. The NTE996 is more durable.
All internal adjustable parameters have been tuned and calibrated.
Cosmetically it is in pretty reasonable shape. It does show some wear and tear but overall nothing too outrageous considering it’s age. The worst thing in my opinion would be some curling at the corners of the stickers on the left hand side front panel. See pictures.
Included with this sale are five spare Polycom cards and three MM5823N frequency divider IC’s to further increase the potential lifespan of this machine."
