Here’s a working Polymoog 203a Synthesizer in nice cosmetic condition. Service by Synthchaser was completed in February 2025. Work done included:
- Recapped power supply
- Recapped all tantalum capacitors
- Cleaned slide pots
- Cleaned key contacts
- Calibrated synthesizer
- Replaced panel button LEDs with new, lower current LEDs – reduces synthesizer power consumption by over 1/4 Amp and increases LED lifespan.
Synthesizer is in good physical and operational condition. The only minor things worth mentioning are the “.” part/full mode defaults to on when the synthesizer is powered up (normally I see this defaulting to off), the “1” preset button sometimes sticks down, and there is a small hole in the case that was plugged where a switch for a mod was removed.
The Polymoog Synthesizer was made by Moog between 1975 and 1980. Its 71 key weighted keyboard, 45 slide pots, and bombastically engineered grandiose design (which included 3-band multi-mode resonators, keyboard dynamic response, custom IC chips, and nearly 100 circuit boards inside) made it the pinnacle of 1970’s synthesizer excess. The Polymoog Synthesizer was used by Rick Wakeman all over Yes’ Going For The One and Tormato albums. A later stripped-down, largely preset version of this synthesizer, the 280a model, was notably used by Gary Numan (“Cars”).
Prospective buyers are welcome to come try it out before purchasing. This item is cross-posted and subject to prior sale.
Shipping is available within the US, contact me for details. If being shipped the item will be sold in “Non-Functioning” condition, as-is, for parts or repair with no returns. It will be packed well and insured for the full purchase price against loss or physical damage, but this is a Polymoog, a notoriously unreliable model (in my opinion due to its large number of poor quality interconnects), and I can only guarantee this to be functional, as it is now, at the time of an in person pickup.
