Wine Country Sequential Is Winding Down

This the end of an era. Wine Country Sequential was formed by ex Sequential Circuits employees when the original Sequential Circuits went under. They specialized in servicing and providing parts for vintage Sequential Circuits synths. I actually own a Wine Country "Perfect Prophet-5" myself.

via Wine Country Sequential:

"The Long & Winding Road Ends..Soon

It's been 46 years since musicians experienced the polyphonic sounds of a Prophet-5, and 41 years since the Prophet 600 introduced MIDI to the world. Sequential Circuits Prophets have made significant contributions to music, film, & theatre for decades. Since 1987 keeping the Prophet sound alive has always been the goal of Wine Country Sequential, and it's been a long and interesting ride. The ride is now over, Wine Country Sequential repair services for Sequential Circuits Prophets ended in December 2023. However, Wine Country Sequential remains open for business as the liquidation of original Sequential Circuits parts & manuals in order to help vintage Prophets survive in the decades to come.

Liquidation of Sequential Circuits parts, manuals & archival documentation continues. Original Operation & Technical Manuals, Printed Circuit Boards, custom IC's, sound programs, Diagnostic ROMs and various other parts are available for most Sequential Circuits instruments. Wine Country Sequential will remain open for business in 2024 until the parts are gone.

Visit and for updates reflecting current availability of parts as the liquidation continues.

The Last Restored & Warranted Prophet 600 for sale by Wine Country with a 30 Day Parts & Labor Warranty is currently posted on at

Coming soon to is a Collector's Corner page offering original manuals, memorabilia, brochures, and even complete original engineering fabrication drawing packages for Sequential Circuits Prophets, drum machines, & other synths.

Thank you for your previous interest, and best of luck with your music.

Kind regards from California,
