EEH / SSB Banana 6-voice Analog Polyphonic Synthesizer

Ad scan below.
"In near mint condition, with factory MIDI. Voice boards and PSU recapped, calibrated. The autotune function has been deactivated because we have calibrated the filters to be able to self-oscillate and apparently that is incompatible with the autotune check on startup, but the synth is fully tuned. Copy of user manual (in german), schematics and docs included. 220V version.
The Banana is a 6-voice polyphonic synthesizer that, in terms of design, strongly resembles the famous Oberheim OB-Xa, but it is not an OB-Xa clone. It features an OB-Xa-like voice architecture with two CEM3340 VCOs, a switchable 24dB lowpass/highpass filter based on the SSM2044 chip, and CEM3360 VCAs and CEM3310 Envelope Generators for the six voices. This provides a rich, warm analog sound that is still relevant in modern music productions. The Banana allows for sound editing with the versatile 2 ENVs (envelopes), similar to those found in the OB-Xa, making it a powerful instrument for both complex soundscapes and powerful leads and basslines.
The Banana was produced in West Germany by Electronic Engineering Hoffmann (EEH), in collaboration with Synthesizer Studio Bonn (SSB), and it is the only synthesizer ever released by EEH and distributed by SSB. In 1983, Electronic Engineering Hoffmann (EEH) completed the development of the Banana in collaboration with Synthesizer Studio Bonn (SSB), the world’s first specialized synthesizer store, located in West Germany. SSB had already made a name for itself by creating custom sequencers, including the Synthorama, which was used by Kraftwerk to control their Minimoogs on the legendary Trans-Europe Express.
Production of the Banana ran from 1983 to approximately 1985, after which the synth was discontinued. Only 100 to 300 units were made. This makes it a particularly rare model for collectors or musicians looking for a unique synth.
This model offers a unique opportunity for the serious synthesizer enthusiast or collector who is searching for a rare instrument with historical value.
Don’t miss out on the chance to own a piece of synthesizer history!"

EMS Synthi AKS - Beautiful example just serviced by EMS
Note: links to listings are affiliate links for which the site may be compensated.
via this Reverb listing
"This is an excellent original example of the highly sought-after EMS Synthi AKS. Our client has owned the instrument for over 40 years and used it primarily for home recording until approximately 1995, after which it was stored.
Following inspection, the Synthi AKS was sent to EMS for a full service, with repairs carried out where required. This recent factory-authorised servicing by EMS significantly reduces the uncertainty often associated with vintage Synthi ownership.
Serial number: 45138KS
Cosmetic Appraisal:
The instrument remains in excellent original, unmodified condition. The control surface shows only light age-related wear consistent with a Synthi AKS of this vintage. The Spartanite case presents well, with some marks from use, and the nickel catches and hinges show an expected aged patina while operating correctly. No keys are supplied for the case locks.
This EMS Synthi AKS arrived with a heavily worn set of original matrix pins. To address this, a complete new set has been purchased directly from EMS and is included in the sale.
The service by EMS covered all the critical items, including replacement of ageing power-regulation capacitors, deep cleaning, and calibration. In addition, the following work was carried out by EMS at our request:
1. VCO stabilisation modification implemented
2. All three VCO potentiometers replaced
3. Joystick potentiometer replaced
4. Full set of twenty-one new matrix pins supplied
Details of the repairs carried out by EMS are itemised in the service invoice, a copy of which will be supplied to the new owner. As the manufacturer has carried out the servicing and repairs, we are satisfied that the instrument is operating correctly and it is therefore sold with our 90-day warranty.
This Synthi AKS operates on either 240V or 110V mains supplies via the built-in voltage selector."

The Summer Constellations for Gong, VCS3 and ARP 2600
video upload by R. Reger
"The core of this piece is how the gong interacts with feedback from the VCS3 that I generate by overdriving the synth’s reverb module. If you’re a synth fan, the synth action in the first part of the piece is minimal but gets more involved in the second half."
