2600, 3620, ARP @ 12 September 2018, “No Comments”

“Recently (about a month ago) refurbished by one of the best techs in SoCal (Montoya). It was also previously professionally maintained when I lived up north, about 4 years ago (Siegenthaler). Many 2600s are electronically flaky, and most of any of the keyboards are internally a wreck — but not this pairing. They are electronically in excellent shape, and also are in fairly good shape cosmetically.” Click here to visit listing on eBay

” Classic vintage Arp 2600 analog semi-modular synthesizer with model 3620 keyboard in absolute museum quality condition. This synth was in climate controlled storage, and unused for over 25 years of its life. It has just had a complete refurbishing and had it’s op amps upgraded by RetroLinear, and is absolutely 100% guaranteed to be in perfect operational condition. As you can see from the pictures, this synth is in immaculate cosmetic condition, with only the most minor of rub marks on the case. It’s never been on tour, or used for any live performance. It even smells new! You won’t find a cleaner or more perfectly functioning 2600 anywhere.

This is a model 2601 v1.0. Serial number 143. This version originally had op amps that didn’t sound as good as earlier versions of the 2600, but they weren’t as prone to mechanical problems. These have been replaced with upgraded op amps that combine reliability with the superior sound of the first models of the 2600. A complete listing of the recently completed overhaul is detailed below.

Remove key bed. Clean chassis, remove key bushings and replace with new. Correct geometry. Pull buss bars and springs. Clean keys and install 18 new standoffs. All tantalum caps replaced. All trim pots and sliders replaced. All flux removed and all the boards cleaned. All front panel jacks replaced. New wires installed where needed – most wires from harness saved. Noise generator power mod installed on board 5-1. Reverb gain mod installed on board 4-2. VCF mixer ac coupled mod installed on board 3. Ceramic capacitors audio mod installed on board 4-2. New power supply and sense lines installed. Audio path upgrade mod – replace all OP amps throughout. Calibrated and ground modified for reduced noise. ” Click here to visit listing on eBay

“Super-rare vintage ARP 2600 Semi-Modular Analogue SynthesiSer with matching serial Duo-phonic 3620 silver livery.

They have been well looked after and loved throughout their ownership. However, like with all vintage musical equipment, they are due a service. For example, the sliders and jacks need cleaning and re-greasing. But a very well made and rare piece of equipment that is well worth the money, the time and the love! ” Click here to visit listing on eBay

“I have an ARP 2600 & 3604-P keyboard owned and used By Jack Bruce of the band Cream.

I’m selling as my control room is rather small and I need the finance to put towards some other gear.

Both are in their original boxes and have ‘The Jack Bruce Band’ stenciled on the outside. I have had it refurbished so it is back in fully working order apart from one of the internal speakers isn’t working, I decided to leave it original instead of opening her up and replacing it. I have a certificate of authenticity from Jack’s family to prove it’s provenance. There is no handle on the case of the 2600. I have given the Tolex case a good scrub and it has cleaned up nicely.

Work Carried out by Synth Restore in Bedford by Adrian.

Oscillator1 and 2 were replaced.

Replaced some broken sliders and replaced some that were showing signs of age.

All sliders were cleaned and lubricated.

Replaced many of the slider tops, as almost half were missing.

Serviced the keyboard, and cleaned the key contacts.

Calibrated the oscillators, and filter.

Power supply had the power transistors replaced.”

” Rare Arp 2601 Synthesizer. It’s time for it to be used to create music again! For many years, it was stored in a spare bedroom closet, and for years, I was going to have it restored and brought up to spec, but alas…, I ran out of time and interest… I did plug it in and turn it on… and all three oscillators generated tone, and they seemed fairly steady (no severe audible drift when tuned to A440 while on). However, I did not go through and test all of the functions and/or all the other modules.
You can see that there were some professional modifications added/done on this one (see pics). It may have been done by Phil Ciricco, the synth wizard at CMS. The quality workmanship of the switches/pots installed is evident, although I can’t say for certain:
3620 KYBD- 2 switches added on right side of controls. Function? Not sure.
VCF Potentiometer- Perhaps variable KYBD voltage control? Not sure.
ADSR- A switch installed and Sustain and Release output jacks? Not sure.
The buyer of this unit will need to invest some time and money in testing, calibration, and possibly some repairs, however the Arp 2601’s are rare and well worth the investment. All the switches, knobs are complete and the tolex has no major tears or holes. Some of the slide potentiometers are a little sticky- none are frozen, but they will need to be professionally cleaned and lubed. This unit looks excellent for being almost 40 years old- as if it lived in a recording studio most of it’s life! What you see in the pictures is what you’ll get. It is being sold as with no warranties whatsoever. I will securely pack the unit in two boxes (main unit and keyboard) and insure it for shipment to the lower 48 States of the USA only. Thank you and best wishes creating music!”

“Stunning original condition and superb working order. Complete professional service completed in February 2018 by US Arp specialist. Checked over by our resident synth expert – it is in superb working order. The front panel, controls and keyboard are all superb and undoubtedly in exceptional original condition for a 2600 of this age. The keys of the 3620 keyboard are showing some age in terms of fine scratches and scuffs but overall this is also is excellent condition. The tolex has some wear and scuffs – mostly on the edges – but nothing serious. Overall this is an outstanding example of an exceptional instrument – the best we’ve seen.” Click here to visit listing on eBay

“ARP 2600 – Excellent Condition – Perfect Working Order.

I’m selling my ARP 2600 as unfortunately I’m simply not using it often enough to warrant keeping it.

It was completely refurbished and upgraded by Phil Cirocco in 2013 and has been sitting in my air conditioned studio since then.
The work carried out at that time is as follows:

Power supply – Replacement/upgrade
All sliders – Chemical bath and lube
Reverb Tank – Replacement/upgrade with 17″ tank
Reverb cable microphonic – Replacement
1/8″ Jacks – All replaced
VCO Sliders – All replaced
Panel/Internal Boards – All cleaned
APU – Replaced
VCA – Upgraded
Filter – Upgraded to 4012CX ARP ladder filter
Keyboard Contacts – Cleaned and burnished

Total cost of that work at the time was $2,253.

Since then I have replaced the latch hardware where necessary and prior to this listing I completed a total system test and everything is in perfect working order!

I am happy to hand deliver this synth in Northern California, and for shipping outside please be assured that the 2600 will be professionally packed, shipped, and insured.

Due to the weight/fragility of this item I cannot ship outside of the U.S.”

On 3604 keyboard the rubber bushings are vulcanized leaving the keyboard mechanically noisy but plays OK now and you can replace the rubber yourself.
Some people decide not to bother with this, and get a MIDI converter to control the 2600 console instead .

The serial number had been removed from the inside of this unit sometime in the 70’s.
The cabinet has been recovered nicely years ago with a non factory tolex but looks very good. You couldn’t tell unless you were an expert into these kinds of details. Still looks cool.

2600 “Synthesizer – Arp 2600 ser#261437
Keyboard -3604p #361411

I have been in possession of this synthesizer for 17 years, and during that time has been well cared for. It worked very well for most of the time that I have had it, but in recent years a few things started to go, so I decided to get it back to perfect playing status.
I took it in for a full diagnostic and refurbishing using a local Detroit area synthesizer guru, the great J Beste. J has worked for the likes of Hans Zimmer during his time in California, in music and film, and is currently working independently and with the likes of Jack White’s 3rd Man records in Detroit, among others. His work is impeccable and I highly recommend the talent of such a detailed and knowledgeable specialist. He spent over 6 months meticulously refurbishing this unit to the best of his abilities, including:

-The disassembling, cleaning and lubing of all of the sliders. Full restoration.

-VCO1, VCO2, and VCO3 have been thoroughly diagnosed or rebuilt, and are all working perfectly.

-The power supply has been recapped, to avoid a common power failure that is indicative of this unit, eliminating future power problems.

-The keyboard bushings have been cleaned and lubed, and a few have been replaced.

-The oscillator chip has been rebuilt.

-The synth has been fully calibrated and tuned.

-All hole plugs are in place.

-Unit comes with original power supply cord, and original keyboard connection cord.

-Arp 2600 includes a bag of original patch cords, a patch manual, and operator manual.

-The unit’s original handle has been replaced, as have a few of the hole plugs, a few key bushings, one slider knob, but aside from that everything else is original.

-All jacks have been reviewed and in some cases repositioned or replaced.

Details to be aware of:

The arp’s Tolex, in some places, is naturally worn. Half of the keyboard’s tolex is missing on the half of the keyboard case–luckily the half that is removed when uncased. I have struggled not to replace the Tolex, but in the end I opted not to, as it is relatively inexpensive to have someone else do for you, and some purists might turn away from it for this reason.

One knob on the keyboard panel is missing.”

arp_2600 “This appears to be a 2603 REV G model 2600, and it sounds amazing.

The face plate is in very good condition, especially for it’s age.

When I purchased this in 2009, the previous owner stated that:

– This model has the much sought after Moog ladder filter.

– This unit was serviced by Greg Montalbano of Analog Synth Service prior to the sale (in 2009).

– These upgrades were installed:

1. An audio path op amp upgrade.

2. New power supply.

3. Installed standard three prong jack so that and standard electronic power cord could be used.

4. A cv/gate input mod was installed on the side, so you can patch a single source of each

through all 3 VCOs without using up the mults, or having to patch into the front.

This has been very useful.

Known issues:

VCO 2 doesn’t work.

VCO 3 pulse output doesn’t work.

These are both recent, but are an easy and inexpensive replacement.

Parts are easily available online.

The decay slider on the ADSR envelope works, but should be addressed.

The bottom for the wooden case, under one of the rubber feet, is starting to dry out.

The tolex is worn, and has been coated with something (prior to my having this) as a temporary fix.

The handle has been removed and there is no cover.

This unit needs a bit of attention, but this is a great opportunity to get a highly sought after synth for a good price. It will be well worth the effort to restore.” Click here to visit listing on eBay

26003604 “FOR AUCTION: an original 1971 Tonus logo ARP 2600 semi modular analog synthesizer (model 2600P V1.0 according to discretesynthesizers.com, this is a pre-26xxx serial), complete with its original model 3604-P keyboard. I’ve owned and maintained this synthesizer for about 7 years, purchased locally from its original owner who had it in the back of his closet for years.

Condition: physically and electronically, this is among the nicest ARP synthesizers you’ll find from this era- even the Tolex on the synthesizer is in great shape (only the removable lids have notable peeling and I probably wouldn’t want to rely on them for heavy transport). Electronically, I initially had it restored by Greg Montalbano in Oakland (analogsynthservice.com) who, in addition to general restorative cleaning, also recapped the power supply, replaced the epoxy’d filter with the lower noise CMS 4012 and replaced the internal speakers with new ones purchased from the late Kevin Lightner. It has subsequently been maintained by Chris Hewitt / thisoldsynth.com who I had replace the epoxy’d VCO 2 submodule with a new CMS 4017; you can see his blog for the repair here: http://thisoldsynth.com/blog/2012/03/05/arp-2600-with-bad-vco/ . Both of the original ARP submodules that I’ve replaced will be included.

What’s included: Arp 2600 with keyboard and lids, original power cord, and cable that connects the keyboard to the synthesizer. Two Switchcraft Tiniplugs for shorting internal connections and a few gray patch cables to get you started patching the synthesizer.

What to expect: the synthesizer is in great condition but ultimately behaves like any synthesizer from the 1971– this is not a 2017 Moog Voyager, this will need time to warm up for the oscillators’ frequency to stabilize and the signal path is a little dirtier. The cable that connects the keyboard to the synthesizer is a little sensitive– it could be cleaned or replaced although you’re not going to notice this other than when you plug the two together. You will overdrive/distort the signal mixer if you run multiple VCOs/sound sources into it at too high of a collective volume– this is normal and I believe the CMS 4017 oscillator (VCO 2) outputs a hotter signal in general; you can back down the VCO levels to keep your tone clean or you can overdrive it by choice as with any mixer. The spring reverb is not isolated from the cabinet well at all– it is *very* sensitive to movement; both techs I’ve had work on the ARP have offered to isolate it but I absolutely love it the way it is, it is a gorgeous, messy reverb. I think the 2600 makes a great general spring unit, you can run a guitar or other signal right into the preamp. Ultimately, it’s in great shape but make sure you have a tech who can work on it should anything ever go wrong. It’s a heavy synthesizer and shipping will always be a real expense if you don’t have a local tech. Also– you can ignore the “Arpeggiator / Sequencer” part of eBay’s pre-populated product description, that’s inaccurate.”

ARP 2600 sn2601020x For Sale. This late model 2601 came to us in working order, but, as perfectionists, we wanted it to work like new or better for its next owner and hopefully continue to work well long into the future, so we fully disassembled it, cleaned it inside and out, thoroughly serviced it, rebuilt it and recalibrated it – a costly process taking approximately 19 hours of skilled vintage synth repair tech time. Now that its restoration is complete, it’s a pleasure to play and should make its next owner extremely happy. Unlike earlier models, all circuits inside this model are unencapsulated, with the exception of the ARP 4012 Moog filter. This means this unit will be much easier to service in the future, if need be. This sale includes a power cord. This unit isnt being sold with a keyboard, so be prepared to run it using a MIDI to CV converter, as most people do these days. This unit is in significantly better cosmetic shape than the other we currently have listed on ebay and is therefore priced higher. It’s absolutely gorgeous. Ebay only lets us post 12 photos.

2. New power supply.

3. Installed standard three prong jack so that and standard electronic power cord could be used.

4. A cv/gate input mod was installed on the side, so you can patch a single source of each

through all 3 VCOs without using up the mults, or having to patch into the front.

This has been very useful.

Known issues:

VCO 2 doesn’t work.

VCO 3 pulse output doesn’t work.

These are both recent, but are an easy and inexpensive replacement.

Parts are easily available online.

The decay slider on the ADSR envelope works, but should be addressed.

The bottom for the wooden case, under one of the rubber feet, is starting to dry out.

The tolex is worn, and has been coated with something (prior to my having this) as a temporary fix.

The handle has been removed and there is no cover.”

2600 “She’s a Tonus Arp (V2600p 2.0) so has great 4027 VCOs and the 4012 “Moog” ladder filter.
This Synth has it all and it is a dream to have owned it.

ABSOLUTLEY complete. Comes with original keyboard, patch cables, owner’s manual and v rare suggested patches booklet.

Cosmetics are great and there are no horrors and though the case does show some patina (this is an old synth!) there is no peeling tolex or dented wood etc etc. She looks good!

Functionality is virtually perfect minus scratchy reverb tank sliders and a loose Cinch Jones. (Entire new Reverb tank is only $40 and the Cinch Jones are known to oxidize, which is an easy fix with some cleaner). ” Click here to visit listing on eBay

2600 “we wanted it to work like new or better for its next owner, so we fully disassembled it, cleaned it inside and out, thoroughly serviced it, rebuilt it and recalibrated it – a costly process taking approximately 20 hours of skilled vintage synth repair tech time. Now that its restoration is complete, it’s a pleasure to play and should make its next owner extremely happy. Unlike earlier models, all circuits inside this model are unencapsulated, with the exception of the ARP 4012 Moog filter. This means this unit will be much easier to service in the future, if need be. If you look closely at the pics, you’ll notice a switch was added under the headphone jack. It’s not wired to anything, but could be used for a future modification. This sale includes a power cord. There’s no lid or keyboard, but most people’s lids end up taking up space in their closet along with their keyboards since these are better controlled via a MIDI to CV converter. Please be sure to view the full sized images so you see there’s engraving on the upper left and button right corners of the front panel.” Click here to visit listing on eBay

2600, 3604, ARP @ 30 November 2016, Comments Off on ARP 2600 with ARP 3604 Keyboard

26003604 ” For auction is an ARP 2600 v3 analog synthesizer with case cover and the coveted copper-cased 4012 Moog-ladder-filter-type filter as well as an original 3604 keyboard with case cover, featuring tuning, scaling, and portamento controls. The auction includes the connector cable that connects the synthesizer to the keyboard, the original power cable, seven 1/8th inch patch cables, and a plug for the filter section to defeat keyboard scaling of the filter cutoff, if desired.

This synthesizer is fully-functional. It was just serviced and cleaned by a very competent tech, and the keyboard was re-bushed.

The jacks have seen a lot of use, and are, in high-traffic patch areas, somewhat loose. Repositioning the cable (of the type included) is often required when patching in the CV region of the filter. The cable that connects the synth to the keyboard is fully functional, but is loose enough in general that you might not want to do an Edgar Winters (although there are guitar strap pegs on the edges of the keyboard!). These issues are very minor, but I wanted to be clear about them.

The tolex on the synth, the keyboard, and their case covers is original, and has wear, some slight tears, and one big tear on the bottom (see pictures). All of the fasteners are functional, but they and the other metal outer aspects on the case are worn with some spotting. One of the feet is loose, but simply requires tightening from inside the case. The faces of the synthesizer and of the keyboard are in good condition, and feature original caps and knobs.

This sale is undoubtedly one I will live to regret. I bought this synthesizer in 2006, and it has been one of the best synthesizers I have ever owned. I have used it in countless recordings, and it has served me well. It has lived in my cool, dry, smoke-free studio, and has been treated with care and respect. I am only selling it because I need funding for a business venture.” Click here to visit listing on eBay

2600, 3620, ARP @ 23 November 2016, Comments Off on ARP 2600 with ARP 3620 Keyboard

26003620 “This ARP 2600 synthesizer (model 2601) and 2630 keyboard come from my husband’s home studio. I don’t know anything about them. I don’t know if they work or not. I can see that there are a few knobs missing on the 2600. The ID plate has fallen off the ARP. It says, “Model 2601 Synthesizer S/N 2601 – 0286.” Both units include wood cases. They come from a clean, smoke free home. I will not ship these items. This is for a Home Pick Up only. ” Click here to visit listing on eBay

2600 “For sale is a rare Arp 2600 synthesizer with the more advanced duophonic 3620 keyboard. Serial number on main unit and keyboard are matching, which is quite hard to find. This is a very clean example in excellent condition cosmetically, it’s amazing how nice it looks. Graphics on the unit are very crisp and easy to read, and only minor signs of wear to be found on the unit. Check out the pictures below for more details to make sure you like it.

The main unit was fully serviced just last month and is 100% functional. The servicing cost over $1000. The unit is all original except for a brand new reverb tank. This is an early 2601 v1.0 version with the 4012 Moog filter. The only thing worth noting is the keyboard has not been serviced, it does have a few keys that don’t trigger properly, it just needs a simple cleaning of the key bus bar & contacts. It could also possibly use new bushings if desired. Otherwise everything is working as it should. You aren’t likely to find a nicer 260 with Moog filter and the 3620 keyboard anytime soon. Nothing sounds like these old Arps, the newer Eurorack modular stuff doesn’t even come close to the tone of these old analog beasts. Perfect for soundtrack work, effects, leads, external audio processing and inspiration in your studio. Don’t miss out!” Click here to visit listing on eBay
