Vintage Moog Modular System 1960’s-1970’s

via this auction

"Interested in a one of a kind Super Rare Unique Moog Modular 18 Oscillators Mean Machine ?

If you want a Moog modular this is the one.

All the most important modules are here and more. 2 complete sets of filters, 2 filterbanks and
(901c & 1630 very hard to find) among others. From late 60s to early 70s.

It’s almost like having 2 moog systems in one. ( IIIc and system 55 )+ compliment B.

All wood except the complement B is in tolex.

There’s a vintage deluxe memory-man delay on the top tier and sounds amazing. The two bottom cabinets are original the other 3 custom I Think. If you remake new cabinets this unique modular will look amazing.

I also have the joystick 🕹 and moog drum snare trigger.

It’s commes with 4 power supply the main big one original and the other 3 custom.

I didn’t have time to build the power supply for the phase shifter 1630 because the module needs -15v/+15v. Every thing is working but these old synths after shipping needs some tune up or calibration."

MOOG CEMS unique original custom modular - VEMIA

"ONE OF THE TWO OR THREE MOST IMPORTANT MOOG CUSTOM MODULAR SYSTEMS IN THE WORLD. This is the system Joel Chadabe dreamt up, in collaboration with Robert Moog, and had him build in the late 60s. It is at VEMIA, undergoing restoration - more details later - but is a unique and hugely powerful system, full of Moog custom modules, some very rare, some very early, and some almost certainly unique. Joel Chadabe's book 'Electric Sound' pp286-287: 'In 1966, I got an idea. I drew up a plan for a completely automated synthesizer system, discussed its feasibility with Robert Moog, described it in an article in 'New Perspectives in Music', and got the funding to have it built. That system, which I called the CEMS (Coordinated Electronic Music Studio) System, was ordered from Moog in 1967.... and installed in December 1969. In addition to an extended array of sound-generating and processing modules, an automated matrix mixer, and a digital clock, the system contained a bank of eight analog sequencers with customised logic hardware for running them synchronously, asynchronously, in succession, or in any combination.' '... the world's largest concentration of Moog sequencers.......' 'In 'Drift'.. (1970), icy electronic sounds swooped automatically through a virtual space without my intervention or control. It was the realtime equivalent of algorithmic composition..' '... a few months later, I was using joysticks to control oscillators, filters, modulators and amplifiers. The sequencers, configured to generate pseudo-random patterns, were also controlling the oscillators, filters, modulators and amplifiers. And I was also controlling the sequencers...... .. I was in effect conversing with a musical instrument that seemed to have its own interesting personality.' The CEMS is housed in four tall vertical cabinets, on casters. 1. 4x 960 (s/n 1094-S, 1096-S, 1103-S etc) 4 x 962 (s/n 1062, 1063 etc) 4 x custom delay mixers, 20 trunk lines. All R.A.Moog, mostly 9/69. 2. 4x 901 VCOs, trunks, Portamento, 2x multiples, CP-3 mixer, 984 mixer, 901, Portamento, 911, 2x 902, multiples, Portamento, 901, 904B, 904C, 904A, 904B, pitch/trigger interface, 912, S-trig>V-trig with portamento, 902, 911, multiples, 911, Attenuators, 911, 903, multiples, 3-pin sockets for joysticks etc, Delays, trunk lines. 3. 'Moogus Operandi' 10 digital numeric switches, 104ms- 4 sec delays, with x1 and x100 switches, digital clock with nixie tubes, trunk section with type B sockets (one line empty), 3x 4U Voltage Controlled Mixers, Portamento (R A Moog, no logo), 905, Triggered Controller, R A Moog banana & 3-pin interfaces, 904B, 902, 902, 911, R A Moog Signal Router, Amplifier, 3x Triggered Controller, PSU, delays and trunk lines. 4. similar to cabinet 1. **It also includes five R A Moog joysticks, serial numbers 1002, 1003, 1004, 1005, and... 1008. - and a pre-production model Ribbon Controller, which Mike Bucki at Modusonics can provide a new ribbon for.** Like many other things in this auction, this is from the collection amassed by Felix Visser, former head of Synton. All items were destined for a national technology museum project, many years in the making, but finally cancelled by politicians and planners. They have mostly been stored unused for a number of years. This system has not (as of March 20) been powered up, and is SOLD AS IS unless we have more information in the meantime. (The power supplies are currently at Lucid Sound for testing and servicing where necessary.) Cosmetic state at present: all sequencer lamps present and guaranteed working 100%; all screws, nuts and washers checked, cleaned and replaced where necessary; veneer repaired on the facing edges of cabinets where necessary; casters replaced; module panels cleaned and looking good; many of the silver knob inserts are missing - many are saved ready to stick back on, but some are lost. (We are searching for replacements, or failing that, new knobs are still generally available.) The quality of early Moog modules is remarkable, and we would expect it to be not at all difficult or expensive to restore this to excellent working order - and beautiful cosmetic condition as well. If required, we can source and supervise this work, and would expect it to be very reasonably priced. All photos were taken before cosmetic restoration, and the system now looks a great deal better - superb apart from the missing silver knob inserts. For more of the old pics see: link"

Very Early Moog Modular 903 White Sound Source Module


via Thesis Audio Service:

"We are restoring a Moog Modular for a client which has an early (1968) 903 module labelled 'White Sound Source'. This module is far more rare than the later 903-a module that was widely produced that had white and pink noise outputs.

This module is hand made on a perf board with pint to point wiring, before the 903-a printed circuit board version. It's possible that this module was handled by Dr. Moog himself (!)"

You can find demos of the 903 previously posted here. The 903 white noise module was featured in only a handful of previous posts. Note the 903-A, a different module, was a Random Signal Generator.

RA Moog Modular 10 Analog Synthesizer

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

via this auction

Update new pics of the inside via this auction.

"The background: this synth is in no way functioning. I was told by the previous owner that I purchased it from that he rescued it from a barn fire and it hasn't been working for a while. Over time he had a few of the modules repaired to fully working condition and ended up selling those off but never got around to the ones that are still contained in the modular 10 case. This means that 1. this is NOT a complete Modular 10 system and 2. this is NOT functioning. The modules that were fixed up and sold off were replaced by the previous owner by Synthesizers.com modules, which I would assume are working but cannot guarantee. I am not in a rush to sell this auction, so please don't send comments arguing about the price - it is what it is.

Included in the listing are the following modules:
911 R.A. Moog Envelope Generator
907 R.A. Moog Fixed Filter Bank
904-A R.A. Moog Voltage Controlled Low Pass Filter
902 R.A. Moog Voltage Controlled Amplifier
903-A R.A. Moog Random Signal Generator
910 R.A. Moog Power Supply
901 R.A. Moog Voltage Controlled Oscillator
Moog Model 10 bottom panel includes a Mixer, Reversible Attenuators, Controller Outputs, Trunk Lines and Power modules
Additionally, a Synthesizers.com Q124 Multiples Module"

MOOG System 12 Modular


Click here for shots via this auction.

Details:
"The synth was built on 9/21/73 and also has some of the original R A Moog modules. Also included are eleven of the original 1/4 audio patch cords, 4 trigger patch cords, Moog Modular service manual and a photocopy of the Moog System 15 users manual. All of the modules on the synth are complete (including the original knobs), work perfectly and were never adjusted or re-calibrated (which can be done with the use of the included service manual, if you know what you are doing!). The keyboard is also complete and works properly including the gold contacts which were just cleaned with De-Ox compound. Both original covers for the keyboard and main cabinet are also included. The original socket recepticle on the power cord was cracked, partially disintegrated and was replaced by seperate crimped connectors (its not original but is does work and is electrically safe!) The cabinet tolex is in good shape with no rips or tears but has been refinished to cover the stenciling that the original owner (which was a west coast college) painted numbers on it for inventory and theft control. The pictures show the current tolex condition which looks 100 percent better then it did when I got it! The original modules, power supply and cabinet still have the original yellow Moog manufacturing stickers in place. Now the upgrade part! - three new modules were added to replace the original Moog 907 fixed filter bank module, which in my opinion is a glorified EQ!. These new modules were made by Mike Bucki at Moog Custom Engineering and consist of a 904B High Pass Filter, 911A Dual Trigger Delay and 1528 Sample and Hold. The original Moog and some of the R A Moog modules consist of a 902 VCA, 903 Noise Source, 904A Low Pass Filter, two 911 Envelope Generators. 921 oscillator, 921A Oscillator Driver and two 921B Oscillators."

Moog Modular Synthesizer


via this auction

"Incredible custom rack-mounted Moog Modular synthesizer. The piece was custom racked by Steve Masucci from tested modules. The ultimate in vintage synthesizers. 100% working and in very good physical condition. The unit has two 901b oscillators and a 901a controller - the 901s sound the best of all the moog modular oscillators - in my opinion. Other modules include the venerable 904a low pass filter, voltage controlled amplifier, envelope generator, noise, and mixer. The modules are in two pieces in black front panels. The synthesizer will be sold as-is due to the vintage nature of the instrument. The instrument is approximately 19" tall (by 19" wide). The modules are powered by a modern International Power Supply with a power switch and fuse added next to the mixer (the glowing red light indicates that the unit is on). The harness and power to all the modules work. There are paper tags stuck on the back of the modules: 901a Serial # 1083 JUL6 1968 R.A. Moog Co Trumansburg N.Y., 901b Serial # 1255 JUL6 1968, 901b Serial #1254 JUL6 1968, Model 902 no serial number but printed TEST STANDARD also R.A. Moog Co Trumansburg N.Y. The envelope generator is fairly new - labeled ©1996 Moog Music Inc. There is no label on the 904a or the 903 but both appear to be vintage and in excellent condition. All the modules except for the Envelope Generator read R.A. Moog on the front panel. The envelope generator reads Moog with the icon in the first o."

Rick Powell 1969 RA Moog 1p/2p Modular Up for Auction

Note: Auction links are affiliate links for which the site may be compensated.
via this auction

via the listing: "RA MOOG modular synthesizer system built in 1969. This 1p/2p custom system built especially for Rick Powell in 1969.

Rick was a musician, a producer and a close friend of Robert Moog.

This is one of only a few completely intact RA Moog factory built custom systems specifically built for a customer during the RA Moog period.

Rick Powell used this unit on his “Choir Book” LP (also featured on LP cover) and also the “Switched On Country” LP.

System was built with a RA Moog 950 keyboard (serial 2048) which is in very good condition. The modules are as shown. 4 of the 902 voltage controller amplifiers, 2 of the 911 envelope generators, a 907 fixed filter bank, a 904-A voltage controlled low pass filter, a 904-B voltage controlled high pass filter, a 901-A oscillator controller, a 901-B oscillator, a 903 white sound source, a 901 voltage controlled oscillator and 2 of the mixer units. Both keyboard and cabinet interconnect cables are included. The 901 has a common factory mod to regulate thermal changes which cause drift.

I Bought this unit directly from Rick Powell’s widow and drove cross country from Los Angeles to Florida to pick it up. I wanted to avoid shipping it. Months later I drove it cross country again to Georgia to drop it off with Phil Cirocco of C.M.S. Phil Cirocco at C.M.S. is by far the most knowledgeable, talented, experienced and careful modular synthesizer technician in the world. Though I requested Phil restore the unit meticulously at to factory operating spec, I also insisted the entire system remain as factory stock as possible and all replaced electronic parts be in harmony with the original production parts. A great deal of Phil’s time was used to make this system as perfect as possible and operating to original factory spec. The bill for servicing was a substantial investment. At the time of servicing I had planned to keep this unit and spared no expense. Recently however I was fortunate to have the opportunity to purchase a more desirable system and so I will let this beautiful perfectly restored system go to a new home.

This is a very rare chance to own an original RA Moog factory assembled unit with interesting provenance. It is also a rare chance to own a Moog system so expertly and carefully electronically restored."

Rare Vintage Moog 981 Mixer Module from 1967


This one is in via Thesis Audio Service who had the following to say:

"I came across this very rare module in a 1968 Moog IIIp that we are restoring for a client. It is a model 981 four channel mixer which I can find very little info about. It appears in the classic Wendy Carlos modular picture and in some Max Brand pictures. There is no mention of it in any of my Moog archive literature or service documents. I have included the schematic that I derived from it. It is an AC coupled mixer for audio. All of the IIIp system pictures that you find show a multiple panel in it's location in the system. The IIIp that we have is dated 1968, but this module is dated 1967. It's a bit of a Moog unicorn, possibly built by the master's hands himself."

I believe this is the first Moog Model 981 module to be featured on the site. You can see the Model number designated as 981 in the image below. The serial number is 1002 and the date is NOV 10 1967. R.A. MOOG CO. TRUMANSBURG N.Y. is on the label. You can find a circuit diagram below as well.

Thesis Audio Service also sent in the rare Moog Model 903 White Sound Source posted here.

Vintage Moog IIIc Modular System

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

via this VEMIA auction

"The Moog IIIc has been with the current Owner since 1999 having been purchased from Martin Newcomb's Synthesiser Museum outside London. This IIIc contains the early 901B Oscillators and not the later 920 range. The IIIC is in pretty good condition for its age as can be seen in the photographs. The corners of the bottom of the Lower cabinet have been scuffed but otherwise the cabinets are in good condition (and very heavy). The modules in the Cabinets are: Top Cabinet: 2 x 690 Sequential Controllers 2 x 962 Sequential Switches 1 multiple 1 961 Interface Middle Cabinet: 1 x 914 Fixed Filter Bank 1 x 905 Reverb Unit 1 x Control Voltage Switches (all switches illuminate) 1 x 904B Voltage controlled High Pass Filter 1 x 904C Filter Coupler 1 x 904A Voltage Controlled Low Pass Filter 3x 902 Voltage Controlled Amplifiers 1 x Trigger and Envelope Voltages (all switches illuminate) 3 x 911 Envelope Generators 1x 911A Dual Trigger Delay 1 x 912 Envelope Follower Lower Cabinet: 3 repeated groups of: 1 x Input control sector switches (all switches illuminate) 1 x 901A Oscillator Controller 3 x 901B Oscillators 1 x Submixer 1 group: 1 x 901 Voltage Controlled Oscillator 1 x submixer 1x 903 White Noise Source 1 x Pitch and Trigger Multiple 1 x 984 Four Channel Mixer 1 x Power and fuse Panel Additionally there is: 1 x 951 Keyboard Controller 1 x Copy of an original Moog Modular Owners Manual (seller does not own the original manual) Additional Information: All Modules are labelled RA MOOG with the exception of 1 of the 960 Sequential Controllers and the 904A Low Pass Filter which are labelled Moog. The Moog was serviced about 2 years ago by James Walker at Synth Repair. Moog (in the USA) updated some control components in the 901A Oscillator Controllers (not the Oscillators themselves) so that the 901A Oscillators can now tune to scale across the full 5 Octaves. This modification does not of course alter the Oscillator tone. James Walker then replicated this modification to the other 2 x 901A Oscillator Controllers. Prior to this update the Synthesiser only accurately scaled across a single Octave. It is 110V but I will include the two 240V to 110V step down transformer power supplies that I have for it for in in the description (one for the top cabinet with the 960 sequences and the other that drives cabinets one and two which are interlinked so only need one supply source). VEMIA should be able to arrange collection and delivery by hand to large areas of North-Western Europe."

Gershon Kingsley's Moog Modular System Up for Auction

Note: Auction links are affiliate links for which the site may be compensated.
via this auction

This is the one featured in this video posted yesterday.

"This extraordinary and historic Moog modular system has been completely and expertly restored to full working conditon by E.A.R.S./The Analog Lab of New York City. They are New York's premier repair and restoration center for analog synths, and head tech Jeff Blenkinsopp has spent months (and I have spent several thousand dollars) on this restoration. All jacks, switches, and knobs have been thoroughly cleaned, all faulty modules have been repaired, the keyboard has new bushings for a smooth and consistent action, and it's tuning has been re-scaled, etc. In fact, the tuning is as good as you'll ever find on a 5 octave Moog keyboard- you can play the entire range and it will still be in tune with itself. Also, 3 of the oscillators had a factory mod done which makes the tuning more stable on them. This was done at the factory by Moog Custom Engineering, not by a third party. Everything else on the whole system is totally original and stock. A link to a video,below, allows you to hear the synth as well as see it, but first a bit more about what modules it consists of and it's history:
It is actually several things put together- the guts of the system , over half of it, was the original modular system first owned by Gershon Kingsley. He was a famous synth pioneer of the 60's and a good friend of Bob Moog's. He used it in a group called The Moog Quartet, who famously gave the first ever live public performances of a synthesizer at The Museum of Modern Art in Manhattan. By the way, Gershon will be celebrating his 90th birthday this fall with a performance in NewYork at Lincoln Center and has expressed an interest in using this synth for it. If the buyer is on the East coast of the U.S. I can put you in touch with him, and you might be able to rent him the system for that performance.
Several modules were added over the years, such as the reverb module (a great sounding spring reverb), and finally around 1977 the double sequencer cabinet. Most of the modules are dated Jan.1969 (they are stamped inside), some Oct.1969, some 1971, a few later than that.
It is a huge system, with 6 oscillators, 4 filters (2 low pass, one high pass, & one fixed filter bank), 2 VCA's, 4 envelope generators, and many other modules, some quite rare (such as the filter coupler) and topped off with 2 sequencers, complete with sequential switches and a sequential interface A complete list of the modules follows. with cabinet #1 being the furthest left in the photos, #4 all the way to the right:
Cabinet 1: 1x 904a Low Pass Filter, 1x 904b High Pass Filter, 1x 904c Filter Coupler, 1x 911a Dual Trigger Delay, 1x 903 White Sound Source, Control Voltages (no model #), 6 blanks
Cabinet 2: 1x 901 VCO, 1x 903a Random Signal Generator, 1x 905 reverb unit, 1x 995 attenuator, 1x 912 envelope follower, 3x 901a oscillator controllers, 5x 901b oscillators, 2x 4 channel mixer modules (no model #) Cabinet 3: 1x 907 Fixed Filter Bank, 1x 904a Low Pass Filter, Filter and Attenuator (no ID #), 2x 902 VCAs, 4x 911 Envelope Generators, 1x 911a Dual Trigger Delay, 2x 962 Sequential Switches, Envelope and Trigger Voltage Module (no model #), Mult module, Power Module w/ trigger and pitch in/out (no model#)
Cabinet 4: 2x 960 Sequential Controllers, 1x 961 Sequential interface,

Here is a link to a video made by The Analog Lab, who just completed the restoration.

Magnificent R.A. Moog modular (60s)


via Vemia

"One of the five or so most important items we have ever had in VEMIA: a large R.A. Moog modular hand-made for one client in stages from 1968-1970, in excellent condition and complete working order. This wonderful instrument is being serviced and renovated by Stephen Masucci, one of the very top Moog restorers, as recommended by Dr Thomas Rhea of Moog fame. The current photos were taken before that renovation, and it will be even more beautiful once Stephen has finished with it. It will also sound superb, with its early 901 oscillators etc., etc.. It consists of four beautiful original cabinets, a superb pair of original keyboards, and what could well be unique: a fixed-filter-bank switching device which has all the hallmarks of a Bob Moog one-off. The modules are:- (3) 901 Voltage Controlled Oscillators (1) 901 A Oscillator Controller (4) 901 B Oscillators (3) 902 Voltage Controlled Amplifiers (1) 903 White Sound Source (2) 904 A Voltage Controlled Low Pass Filters (1) 904 B Voltage Controlled High Pass Filter (1) 904 C Filter Coupler (2) 905 Reverberation Units (1) 905 B Scale Programmer (1) 907 Fixed Filter Bank with in/out switch for each filter (1) 910 Power supply circa 1974 (3) 911 Envelope Generators (1) 911 A Dual Trigger Delay (1) 912 Envelope Follower (2) 950 Stacked Keyboards (1) 960 Sequential Controller (1) 961 Sequencer Interface (1) 962 Sequential Switch (1) 4 Input active line level mixer with click filter (1) 4 Input passive line level mixer with low & high pass filters (1) Various patch points including trunk lines and 4 sets of multiples The last two digits of module serial numbers have been removed in the photos because the owner values his privacy. Remember the photos were taken before the roughly $5000 Stephen Masucci restoration. We have asked Mr Masucci for a written appraisal of this instrument, including its condition and the reason why it is important in Moog history - to follow, I hope. The instrument will be packed and shipped from his workshop, so this will be done by someone with much experience of shipping instruments of this size, weight, and quality (including Dr Rhea's own modular). **The restoration is going well as of 13/4/10, but because of Stephen's other commitments for the rest of the month the likely completion date is not till May 7. That will give the winning bidder a few more days to complete the payment.** **If it is bought by someone outside the USA there may be tax / duty to pay by the importer. In the UK, for instance, there would currently be duty at around 3.2% and VAT at 17.5%.**"

Custom Moog Modular System 55 For Sale

"Modules Included: 901, 901A, 3-901B, 4-902, 903, 2-904A, 904B, 907A, 4-911, 911A, 921, 951, 960, 961CP, 962CP, 984, 991, custom 994 (3x), 2-CP3A, CP4A, upgraded CP8A


This Custom Moog Modular System 55 has two very unique features: Two 904A low pass filters and both the 901 and 921 series oscillators. Having two 904A's greatly expands the flexibility of the sound engine and the addition of the 921 control oscillator adds functionality while maintaining the richness of the sonically superior 901 series. The system also has an upgraded power supply which helps maintain oscillator stability. This synthesizer was not designed to be looked at or used as a fancy minimoog -it was built to be a complete and complex electronic sound machine. $62,000.00 For show in LA, CA. Serious inquires and buyers only contact: info@aisounddesign.com"

Update via 3P in the comments: "Not a 55. Module placement is different, the Moog module logos are Trumansburg/Williamsburg era. And there are no 921 Series oscillators."

And via Unknown in the comments, there's actually a 921 in the system. Top row to the left of the four channel mixer, pictured here to the left.

Update2 via the seller: "What is meant by 'System 55' is basically a main cab with single tier, rather than a 35 which was just the main cab. "Module placement is different" ie "Custom." Looks like a 921 and there are a lot of RA Moog logos. This system is a unique design; a hybrid of multiple generations. Also note that the 962CP is very rare, most module lists don't seem to mention it."


Update3 via Brian in the comments: "Likely NOT delivered from the factory that way. It is what it is, but calling it a System 55 is not correct. The 901 oscillators were discontinued in 1972, when the 921's replaced them. At the time, NO ONE felt the 901s were superior in any way (some of us now think differently). I see a mixture of RAMoog (1960s generally) and Moog Music modules there (1972 and later), too.


Again - any customer could order anything from the factory, but it's highly unlikely this was ordered this way; rather it is built from traded in-out components to make a great system. I'd MUCH prefer to have one like this with both sets of oscillators. All the MAJOR synths by major players were not stock catalog versions, but custom rigs for their needs."

Update4: via Moog1P in the comments: " The bottom cabinet looks to be an early 1C configuration. Every component is there, with the blank panels replaced with the 962CP and 961CP. The placement of the two CP3 mixers would have been to the left, under the 901AB bank and under the 901. At some time the system looks to be upgraded with the installed CP961/962 sequencer components, where the CP blanks were removed, and CP3's moved to the right.

Would be an early 1C as this one has the very first Lexan type lighted flip switchs, only seen on late '67, early'68 models. All the correct lexan switches are there, two sets for the oscillators, and a set for the filter, with trigger/envelope routing, making the cabinet a 1C. The 2C would have 3 CP3 mixers, and the 3C would have 4 CP3 mixers with no CP routing switches, as they were on seperate 1U panels for filter and trigger/envelope.


The module placement above is what you would order any way you wanted. Not uncommon to order a 1C with an extra 901C, and to ommit the 905 reverb to add the 904B high pass filter, direct from the factory. Looks like what we have here. The only other addition to the lower cabinet is the 1U blank replaced with 911A trigger delay. And at some time (definitely not Moog), the removal of the Cinch male S-trigger from the 1/2/3 trigger outputs. (Probably done when the CP3's were moved and 961/962CP added.)

The upper cabinet is an add on, possibly at a later time, but could have been part of the original order. At that time the additional 984 quad mixer, envelopes, VCA's were added. The 960 sequencer, probably added much later, when the bottom CP panels were moved. And much later 921 added. Does not look to me to be a unit made from other Moogs, but rather a 1C with a few add-ons. Everything is there from an early 1C with many period correct additions. Very nice unit, only missing the 905 reverb and 956 ribbon controller. Wouldn't take much to undo those questionable mods to restore this to original specs."
