1975 Moog Polymoog Keyboard Synthesizer Model 203A w/Orig 285A Foot Controller


SN 1497 via this auction

"If you are looking at this then you know the problems that these first generation Polymoogs are known for. The first and foremost is the power supply which has been rebuilt already in this unit. Keyboard powers up beautiful with stable voltages present at all locations...

All 71 cards and keys trigger. We removed all the cards and carefully cleaned the contacts and then reseated them...

The VCF and the Resonator circuits work and are surprisingly crisp and present as you blend them in using the Master Gain Controls. The resonator circuit is a little noisy but nothing unusual for a unit this age....

The major problem with this unit is that the Master Keyboard assign push buttons are intermittent at best.. it was looked at and assessed, we determined that the contacts are either oxidized or are failing. We are able to get the Vibes, Funk and Organ buttons to engage with constant and repetitive pushing...but this will have to be addressed since this is the final stop to the output of the keyboard...

Once we got one of those 9 controllers to engage...this thing is INSANE! Very cool sounding and super fun to play. Particularly like the VCF. Instant Emerson, Lake & Palmer!!! Among others...

Cosmetically the Keyboard is in great condition...

There are one maybe two LED's out under the panel switches but they all work...

The resonator pass mode switch is quite scratchy but all three bands engage...

The pitch controller even works!

You can tell this keyboard was used and taken care of. It is being sold as-is because I just don't want to put all the labor and love into shipping it safely and correctly only to have it returned..."
