For sale EMS Synthi AKS serial 4942 in very good shape and excellent working condition.

This beautiful AKS was restored and serviced recently. The shape is very good thinking that is an instrument of near 50 years. Some marks of use and time can be seen, take a look the pictures for close detail. But maybe you know that is very difficult to find this kind of instruments with no marks of time or use. Most important is that this unit was never modified, is full original condition with no drills or non reversible modifications that you find in another units usually seen. This unit looks and works like the original. Also includes the very interesting prestopatch socket. This is definitively the best Synthi A version with this features, finish and wild vintage sound.

Some service details are:

Deep cleaning of all electro mechanic elements, potentiometers and switches. All original potentiometers recovered and working smooth now.

Full polarized recap service, any vintage EMS with original polarized capacitors have surpassed the life span, must be replaced. With this service enjoy more decades of reliable capacitors. Taking care carefully of the compatible values and parts for ensure the original behaviour and sound.

Replaced crackled film capacitors. Some vintage EMS suffers from crackle polyester capacitors that need to be replaced for ensure good work. When requeried, new fresh polyester capacitors are used for this replacement

All bad/crap original trimmers replaced with good quality ones. Added precision multiturn potentiometers at VCO tracking for very musical close matching.

Temperature compensation for VCO 1 and 2 following the EMS bulletin. Now the track and tune keeps very stable for long sessions. Finally is possible to play it musically precise.

And of course the factory adjust and calibration as it should be.


The KS service includes:

-Deep PCB cleaning

-Full polarized recap

-Original potentiometers deep cleaning

-add hi grade turned sockets for all 14 pin ICs. It is very valuable for future service, for easy service and diagnostics.

- New screws for more reliable fixing with board and plastic case.

- Taking care of the original TTL chips needed for ensure original good performance.


Again all the service was taking care and respect of the original sound and behaviour. VCO tracking and temperature compensation was applied following the EMS bulletin. Is really a very recommend upgrade program, but if the user wants undo this upgrade it can be downgraded for VCO non close matched tracking and temperature drift behaviour like the first early units. Let me know if you want it downgraded for undo the internal upgrade.

Included with this Synthi AKS system:

Keyboard 1,50 meter umbilical cable for connect the Synthi A with the KS.

Special umbilical cable for external 2x CV inputs and 1x GATE input. Adapted for the Synthi signal levels. Connect the Synthi A with other synths using CV GATE signals and the easy way for use with MIDI interface like Kenton Pro-solo or Pro2000 or many other MIDI CV converters.

User manual printed (from PDF scan)

Full set of original EMS pins, 14 white pins, 2 red pins, 2 yellow pins, 2 black pins (rare), and 2 green pins (attenuator pins)

This unit can be collected locally in Barcelona. We are very near of the El Prat airport of Barcelona. If you want to come here to play and test and collect and also pay on cash it can be done (and celebrated with good spanish tapas moment at the town) I can also help to anything from the Airport to the studio and again from the studio to the Airport, no problem with that, I understand many situations of this kind of trades and purchases I have many experience with vintage gear and customers around the world, and will be glad to help with something related to that. We speak english, spanish and catalan, and with some help italian and french :)

Of course unit can be shipped to worldwide with special care of the packaging and insurance (for non EU countries customer must be responsible of all cost related to destination country taxes and import duties and extra cost of the clearance)

The shipping cost is high due to the insurance. For ebay or reverb purchase the non insured shipping mode is not available, if you want another option write me to know otpions or consider the pickup in Barcelona option I can offer.

Any question feel free to ask.
