Jen Synx 508, 5-voice Analog Polyphonic Synthesizer

Note: links to listings are affiliate links for which the site may be compensated.


via this Reverb listing

You can find demos of the Jen Synx 508 in additional posts here.

"Jen Synx 508, a extremely rare analog synthesizer, aimed at a collector who can get it working properly. Aesthetically, it's almost perfect, but it has some functional issues that need fixing:

- The sequencer seems to work, but we don't know exactly how to program it.
- Some buttons (hold, memory...) take a while to respond keeping it pressed. As it seems its not a problem of the switches, may be a factory bug.
- Envelope calibration can be improved in some voices.
- Resonance seems unstable, probably is a calibration issue as we're not sure if the filter is supposed to self-oscillate in this synth, but we calibrated it as if it were supposed to.
- The Phaser/Ensemble/Chorus effects are a little noisy, but we think it may be another factory bug as the BBDs are ok.

We haven't found a user manual, but we do have schematics drawn by an Italian technician. It's believed that the Synx 508 never reached full production, mainly due to the sequencer problems that couldn't be resolved with firmware updates. Apparently, the processor used was quite slow, which caused most of the mentioned issues.

8 banks and 8 sound presets per bank. Each voice card comes with a CEM3310 ADSR Envelope, a CEM3320 24dB/Oct 4-pole Multipass filter, and a CEM3360 Dual VCA. There are 5 voice cards, expandable to 8 if you can find spares.

New battery, almost completely recapped, new potentiometers installed, etc."

EMS VCS 3 The Putney SN 3211

Note: links to listings are affiliate links for which the site may be compensated.


via this Reverb listing

"This is a rare chance to secure an original VCS3 in excellent condition. This is one of the most iconic and revered synths of all time.

The VCS3 (nicknamed the Putney) is an analog monosynth housed in a distinctive angled wooden case, a truly classic synth. EMS (Electronic Music Studios) was created in England back in 1969. The VCS3 was one of their first synths and it is still a great, unique, funky little unit! Pictured above is the Mark I model. Pictured is another unit with the small wood-cased DK2 voltage-control keyboard required to play the VCS3.

It has three oscillators, and a unique matrix-based patch system. Instead of patch wires, the VCS3 uses a patchbay grid in which the synth components are laid out, and signal routing is accomplished by placing small pins into the appropriate slots. The VCS3 was, in actuality, a modular type synthesizer reduced down to an extremely portable size.

We are often asked whether mods adversely affects the value of a VCS3. Some collector types may view it as sacrilege, but most who buy a VCS-3 to use often value mods highly – many of our customers ask for more, rather than less, modifications. So, in short, in our view the answer is mods often add value/appeal rather than detract. These wonderful synths should be used rather than placed in glass cases. You won't see another VCS3 with as many perfectly integrated mods as this one has."

EEH / SSB Banana 6-voice Analog Polyphonic Synthesizer

Note: links to listings are affiliate links for which the site may be compensated.




via this Reverb listing

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!"

Two KETRON SOLTON PROGRAMMER 24 synthesizers synchronized with each other and to a MINIMOOG

"ITALIAN
In questo video mostro come suonare contemporaneamente due sintetizzatori KETRON-SOLTON PROGRAMMER 24 sincronizzati tra loro e poi come far suonare la linea di basso di un PROGRAMMER 24 da un sintetizzatore MINIMOOG DODEL D

Il Solton Programmer 24, lanciato nel 1985, è riconosciuto come uno dei primissimi strumenti a introdurre il concetto di arranger automatico nel mercato delle tastiere, tanto da essere spesso definito 'l'apripista' dell'intero settore.
Questo strumento, prodotto dall'azienda italiana Ketron (con il marchio Solton), è considerato una pietra miliare nell'evoluzione delle tastiere arranger.

Impatto Culturale: è stato soprannominato 'Italian Disco Machine' per il suo ruolo nel plasmare il suono della musica Italo Disco.
Il Programmer 24 non è solo un pezzo di storia per gli appassionati, ma è anche al centro di iniziative come 'Arranger Legacy', un progetto web che mira a preservare la memoria di questi strumenti iconici e dei loro creatori.

Il Solton Programmer 24 è una workstation analogica italiana del 1985, famosa per il suo suono Italo Disco, che combina una sezione ritmica PCM a 8 bit (con uscite separate), bassi analogici, arrangiamenti automatici e sequencer, offrendo un suono vintage caldo e funzionale per produzione musicale. Include funzionalità avanzate per l'arrangiamento, sequencer polifonici e monofonici, MIDI, e interfaccia a nastro, rendendolo un pezzo da collezione apprezzato per il suo 'carattere anni '80'.

Kawai K3m w/ Original Box

Note: links to listings are affiliate links for which the site may be compensated.


via this Reverb listing

"For sale is a collector-grade Kawai K3m in excellent condition, the iconic 1986 hybrid rack synthesizer known for its unmistakable blend of digital additive waves and warm analog filters and this one is among the nicest examples you’re likely to come across.

This unit has been exceptionally well cared for. The front panel, buttons, and display are all clean, responsive, and in excellent shape. The chassis shows only very light surface scratches consistent with normal aging and nothing that affects performance or presentation. No rust, no dents, no rack rash. Everything functions exactly as it should. This K3m includes the original box, which is extremely uncommon and makes it especially appealing to any collector who values originality and provenance.

If you’ve been waiting for a near-mint, investment-worthy K3m that has the look, feel, and reliability of a top-tier example, this one checks every box.

The K3m has gained significant interest in recent years thanks to its unique voice architecture: additive digital waveforms running through warm analog filters. It occupies a sonic space very few synthesizers, and certainly no plugin, can convincingly emulate. It’s pure mid-’80s character, from shimmering pads to darkwave textures to cutting synth-pop leads.

Collector Highlights:
• 1986 original in exceptional condition
• Very minimal wear
• Fully functional with no operational issues
• Includes the original box
• Original buttons, screen, and panel components
• Hybrid architecture: 32 digital additive waves → analog low-pass filter
• A historically significant Kawai design with growing collector interest
• Perfect for studios, synth enthusiasts, and vintage rack collectors"

"If you’re looking for an RA Moog–era Minimoog Model D on a budget, this is a great opportunity. The previous owner replaced all four of the original mainboards with new units from SynthRestore.co.uk; unfortunately, the original boards have been lost to time. While this does impact the instrument’s value from a collector’s standpoint, it is fully functional and performs reliably.

The exterior cabinet is in excellent condition and may have been rebuilt or replaced, along with a fresh set of knobs. Overall, it’s a fantastic player’s instrument with vintage character at a more accessible price.

Anthony Marinelli Music Synth Studio Revealed | Studio Tour 2025


video upload by Anthony Marinelli Music

"I finally agreed to make a video showing my synthesizer studio. I'm NOT a collector, so you'll see the instruments I've used for over four decades to do my work. It's also my space for composing. In this deep dive studio tour, I walk you through every corner of my space, showing how everything’s connected for performing, recording, and creative flow.

You’ll see icons like the 'Plantasia' Moog Modular IIIc, Synclavier II, Rhodes Chroma with Expander & Enabler, Oberheim Four Voice, Elka Synthex, Roland Jupiter 8, Sequential Circuits Prophet-5, ARP 2600s, Korg MS modular synths, some classic Minimoog — plus a few modern synths I’ve added as I look to the future. Alongside the synths are vintage drum machines, string machines, and rare electric keyboards including a 1973 Fender Rhodes Suitcase and Hohner Clavinet/Pianet Duo.

We'll also explore racks of outboard gear, vocoder units, tape echoes, and a vast array of my custom guitar pedal options, efx pedal boards and studio effects racks that make this room endlessly inspiring. I'll also reveal how my entire studio is designed for instant creativity, featuring 48 channels of synth drivers and stage boxes, so any synth can be patched and recorded on the fly."

Korg PS-3200 (1978) - Professionally Restored Full System

Note: links to listings are affiliate links for which the site may be compensated.


via this Reverb listing

"Korg PS-3200 - A fully configured system that's been fully cosmetically and operationally restored.

One of the finest fully configured surviving examples of Korg’s iconic PS-3200 — a true masterpiece of 1970s analogue engineering, fully restored for the modern collector.

Servicing Status

KSR has undertaken an extensive cosmetic and operational restoration of this PS-3200, a project spanning several years but largely completed by the end of 2024 — thanks to the exceptional work of Kent Spong of KSR. The Korg has been held in our secure facility throughout 2025, so post-sale, we will have the instrument and all accessories fully checked before shipping or delivering to the new owner. This process will add approximately 10 to 14 days to the post-sale completion time.

Remarks

We have decided to offer for sale our complete Korg PS-3200 System, which forms part of the RL Music Vintage Synthesizer Collection. Over the last 22 years, we’ve retained a small number of the finest vintage synthesizers to pass through our hands — instruments we found particularly inspiring or significant. This PS-3200 is one such example and has been the subject of a full and detailed cosmetic and operational restoration by our trusted vintage synth technician, Kent Spong of KSR.

It is generally accepted that Korg produced only around 200 units of the PS-3200, although the exact number is difficult to verify. Whether 100 or 500 were made, production was certainly very limited, making this an exceptionally rare, hand-built instrument by any measure.

Due to the rarity and individual nature of instruments like this, we’ve taken great care to provide a comprehensive and honest description of this PS-3200. We encourage any prospective buyer to ensure they have all the information needed to make an informed purchase decision — and of course, we are happy to answer any questions directly.

Provenance

We purchased this PS-3200 from a UK seller (an experienced user) in 2015 and collected it personally from their studio in the South of England. At the time, the instrument was fully working but had not been professionally serviced, so we decided to retain it within our PS-series collection — completing the full lineup — and plan its restoration later.

The overall condition was original and very good but showing signs of cosmetic age typical for a 35+-year-old synthesizer. We therefore elected to undertake a full operational and cosmetic restoration. While the market for highly restored vintage synths has cooled in recent years — as values for unrestored examples have climbed — our motivation for this restoration was personal rather than commercial, as the PS-3200 has always been part of our private collection.

System Configuration

PS-3200 Main Frame
PS-3010 Keyboard Controller
PS-3001 Interconnect Cable
PS-3030 Remote
PS-3001 Interconnect Cable (second)
PS-3040 Dual Pedal
Kenton MIDI Retrofit Kit fitted
This particular PS-3200 includes the extremely rare PS-3030 Remote, a unique device allowing live performers access to the patch memories — a groundbreaking feature for 1978.

Rare Vintage KORG KEIO (?) CHECKMATE Drum Machine

Note: links to listings are affiliate links for which the site may be compensated.



via this Reverb listing

This appears to be the first one to be featured on the site. It looks a bit like the Wexler ROCKMATE. Teisco made a CHECKMATE keyboard. You can fhand a handful of posts mentioning CHECKMATE here.

Details via the listing:

"A vintage Checkmate drum machine, a true gem from the early days of rhythm boxes. This unit is as much a visual statement as it is a piece of music history: with its golden front panel and large knobs, it’s a guaranteed eye-catcher in any studio or collection.

Fully serviced: all electrolytic capacitors have been replaced, ensuring reliable operation.

Everything works as it should – all rhythms, switches, and controls have been tested.

Runs on a single 9V battery inside the unit, making it portable and hassle-free.

About the Checkmate

The Checkmate belongs to the family of early preset rhythm machines from the late 1960s/early 1970s, often linked with Korg’s DoncaMatic line. These units were designed for accompaniment but quickly became collectible for their quirky analog character and stunning design.

Limited but charming selection of preset rhythms.

Simple analog sound circuitry with a warm, nostalgic tone.

Rarely seen today, making it highly desirable for collectors of vintage drum machines.

Why You’ll Love It

While it won’t replace a modern drum computer in terms of versatility, the Checkmate delivers something unique:

A rare piece of music history that shaped the early years of electronic rhythm.

Unmatched aesthetics – the gold panel and oversized knobs look fantastic both in use and as a display piece.

Collector’s must-have – these machines are increasingly hard to find in good working order.

If you’re a vintage synth/drum machine enthusiast, this is a rare opportunity to own a serviced and working Checkmate drum machine. Perfect as a collector’s item, studio conversation piece, or source of authentic retro rhythms."
