"They don't make them like this any more.....Literally. Perhaps one of the last chances to grab a classic suitcase synth as the few that were made are fairly tightly held, with good reason. The price is fair, considering one in the same condition sold in the UK in May 2014 for $18,5000. This AKS has been in my studio for the past 35 years but the time has come to pass it on. I have just had it checked by ProHarmonics Aust. Everything is in perfect working condition, including the all important sequencer. It is all original except for the internal speakers, which I replaced a year ago as one had started poling, and one new Vernier pot, which I obtained from Robin Wood of EMS. I also bought some more pins and a new 8-way keyboard connector cable from him. The unit comes with a Power cord, Keyboard connecting cord, Manual (reprint), DVD with circuit diagrams and Matrix Pins:- 15 White (2.7k ohm/5%), 13 Red/Orange (2.7k ohm/1%) and one Green (68k ohm, Attenuation Pin ). Those of you who know the Synthi AKS need no blurb but for those who don’t I’ve put down the following info. 
It features three oscillators and a unique patch system. Instead of patch wires, it uses a patchbay grid wherein the synth components are laid out and signal routing is accomplished by placing small pins into the appropriate slots. The VCS3/Synthi was, in actuality, a modular type synthesizer reduced down to an extremely portable size. Its famous for it’s ability to generate uniquely analog sounds( Dr. Who, Pink Floyd, Eno, Klaus Schultz Pete Townsend, etc ). After ten minutes of warm-up the oscillators become pretty stable. There's a Noise Generator, two Input Amplifiers, one Ring Modulator, one Voltage Controlled Low Pass Filter (VCF), one Trapezoid Envelope Generator, a Joy-Stick Controller, a Voltage Controlled Spring Reverb unit, two Stereo Output Amplifiers and a 256-step on-board monophonic digital sequencer and a 30-note touchplate keyboard. I will ship the unit inside a pelican type case and then packing for total security. Buyer is responsible for any customs or import duty."
