"Beautiful and powerful Odyssey Mk1. One of my favourites for sheer cutting through power. This one has been in my studio for over 20 years with regular servicing by Kent Spong and James Walker whilst in UK and more recently 6 months ago by Antonus in Barcelona. It had a Kenton MIDI kit already retrofitted when I purchased it and I later added CV Gate inputs installed by Kenton in London for added flexibility. It comes with a full Flight case included, which I purchased separately from Vemia in 2017. Selling now I have retired. Not in second chance Sunday."

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.

Of cyclotrons and sequencers: recreating a 1974 “probability controller” in Eurorack

video upload by Electrum Modular

"This is the first video in a new series exploring the University of Iowa’s Electronic Music Studio. In addition to presenting its historic instruments (including a 1968 Moog IIIP with custom-made modules), and the famous musicians who have used them, these videos will extrapolate ideas to use in your own modular systems. This episode examines a unique random sequencer that was developed in 1974 by Paul Dingman, an electrical engineering student at Iowa. It then shows how it might be recreated using the third lane ('time') on Make Noise’s 0-Ctrl. NOTE: several other Eurorack sequencers also have this feature, as indeed does the Moog’s own 960 sequential controller; alternatively, use an LFO to clock any sequencer and patch the sequencer’s second lane/channel (if it has one) back into that LFO’s frequency input.

"One of the greatest polysynths ever made, in excellent condition. I’ve owned it for more than 20 years. It plays beautifully and it hurts to let it go. Kent Spong (KSR) has always serviced it for me, and he’s never needed to do much more than tune the filters. This really sharpens up the sound, and it’s booked in with Kent at the auction end so that the next owner will receive it in fantastic playable condition. Serial number 300. With a MIDI input, fitted prior to my ownership, that I have never used. 240V from new. Comes with both lids, original 240V cables, original 4 voice expander cables and original manual."

The Bob Moog Foundation Fall 2024 Raffle - "No Talking" Demo!

video upload by Pro Synth Network

"We have been very lucky to be involved with helping out on the latest Bob Moog Foundation Raffle. This time, a classic vintage Minimoog Model D, signed by Peter Gabriel and restored by our very own Kent Spong, can be won.

Andrew goes through the gloriously deep, rich and distinctly Moogy tones of this incredibly special raffle prize, signed by the legend that is Peter Gabriel.

There has never been a more important time to support the Foundation. Hurricane Helene tore through Asheville, NC, home of the Moogseum, last month, leaving a trail of destruction in its wake. Although it only sustained minor damage, the loss in trade from being unable to open will hit the Foundation hard.

Buying tickets for the raffle is an excellent way to help out with the added bonus of being able to own this singularly unique and iconic synthesizer.

Look out for more video content to be released throughout the raffle!

Buy tickets here: https://moogfoundation.org/fall-2024-...

Be quick! The raffle ends on the 28th October 2024!

Huge thanks to the amazing and inimitable Michelle Moog-Koussa for this opportunity to support an organisation that is very dear to our hearts. Please support her work however you can."

Roland SH-3A 44-Key Vintage Analog Synthesizer w/ Original Instruction Manual

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

via this listing

"Roland started producing some really unique synthesizers in the mid 1970s, and they were built to a very high standard and certainly have lasted. The SH-3A was conceived as a portable full function analogue synth that had bags of charter and shared much of the same architecture & functionality from the SH-5, SH-7 and even the System 100 etc, so we think this represents excellent value for money.

Background:

Our client purchased this Roland SH-3A new in 1975, so it’s a single owner machine that’s been in their possession for just shy of 50 years, and only ever been used in a home environment. This is a UK model, so 220~240v, and is hard-wired with a UK 3-pin plug which is stored in the compartment within the flight-case in the underside of the synth.

Servicing:

As mentioned above, Kent at KSR has just going the SH-3A a full service, so it’s perfectly working and sounding like a SH-3A should, and he commented that the synth is in beautiful condition inside and out.

Condition:

We rate this as in excellent all original condition, unmodified and complete with its music stand, lid and original owner manual, so very much a collectors grade instrument, that’s ready to play.

Documents:

Although we don’t have the original sale receipt from 1975, the synth does come with its original user manual."

Steelphon S900 // Mellotron M400

video upload by foleytronics fx repair

"This is a demo of Tom’s Steelphon that got whooped by UPS - broken circuit boards, broken MDF case, no output. We took the case to be reproduced by Kent Meloy of Tunguska Guitars and in the meantime went to town on the electronics. There isn’t a schematic available anywhere, but after getting the rails back and the keyboard CV working, there was still no output. I isolated it to the filter board and realized the VCF is a Moog copy, component-for-component, so I used a Minimoog schematic to help troubleshoot the problem.

The Mellotron is mine and has undergone quite a bit of work. New pinch rollers, new motor control board, rebuilt the PSU, and fabbed a new key as one was missing."
