This is a late MK1 with the version B PSU (TIP31 power transistor on a big heatsink on board A) and prestopatch edge connector.

One of the most iconic and collectible analogue synthesizers ever built, the early Mk1 is renowned for its unique sound, portability, and innovative matrix patching system. It has been used on countless classic recordings by artists including Pink Floyd, Brian Eno, Roxy Music, Jean-Michel Jarre, Hawkwind, King Crimson, Kraftwerk, and the BBC Radiophonic Workshop, cementing its place as one of the most influential synthesizers in music history.

Sold together with the Synthi AKS Poly MIDI-CV interface, allowing MIDI control while preserving the originality of the instrument.

The synthesizer is in very good cosmetic condition for its age and has been carefully stored throughout my ownership. Please refer to the photographs for its overall condition.

Included:

• EMS Synthi A Mk1
• Synthi AKS Poly MIDI-CV interface

This is an exceptionally rare opportunity to acquire one of the most sought-after vintage synthesizers ever produced.

I have owned this Synthi for approximately 25 years and am very sad to part with it. It is one of the finest synthesizers ever made—innovative, expressive, and full of character. A true recording classic that has earned its legendary reputation.
