🎹 1973 Thomas Californian 266 – Quadraphonic Analog Organ
Made in the USA • Fully Original • Fully Functional

This is a fully preserved, unmodified Thomas Californian 266 — a quadraphonic electric organ built in 1973 in Chicago, IL. Featuring dual 44-key manuals, a 13-note wooden pedalboard, and dual CTS speakers, it was one of the most technically advanced home organs of its time.

Unlike many vintage instruments, this unit offers not only analog warmth but also integrated quadraphonic output, onboard rhythms, and modular internal design — making it ideal for collectors, studio installations, or retro-sound modeling.
It features a fully analog tone engine with early IC-based control logic — making it a hybrid in control design, while remaining entirely analog in sound.

💡 Why This Organ Is Special:
This isn’t just a vintage piece — it’s a preserved example of American musical innovation. At a time when most home organs were downsizing and cutting corners, Thomas was building machines with full quad output, integrated effects, and tone shaping — all housed in hardwood cabinetry.

Few of the Thomas Californian 266 were made, fewer survive, and almost none remain in this condition. If you’re building a vintage studio, collecting rare analog hardware, or archiving sound history — this is a showcase piece.

📌 Summary:
• 100% original – untouched analog internals
• Legendary quadraphonic output system
• Studio, museum, or performance-worthy condition
• A rare opportunity for collectors and enthusiasts of true American-made electronics
