ARP 2600 with ARP 3604-P Keyboard

“On offer is one original Vintage ARP Analog semi-modular 2600 rare early TONUS Logo series Electronic Music Synthesizer fully restored.
This is the Arp 2600 model 2601 synthesizer, which has long been one of the most highly prized and sought after of the old modular analog synths. It has an amazing combination of limitless flexibility, ease of use and incredibly sweet sound that is almost impossible to find in other synths of its time. However, if you’re looking at this auction you already know all this!

CONDITION:
All components are original except for 2 op amps. One for VCO-1 square wave out and the other for the Mixer amp. Additionally, the left speaker has been replaced. All have been tested and perform up to or better than original specifications.
The case of the synth has a few scratches on it and there is a small nick on the panel near the reverb sliders and on the keyboard panel upper right but overall with the restoration it looks really great. All knobs, slider caps and adjustment covers are present except one cover for the negative null which in no way affects operation. All the markings and legends are pristine.” Click here to visit listing on eBay

ARP 2600 with ARP 3604-P Keyboard

“I purchased this 23 years ago as an investment.When I received it was fully functional and I was able to nail a bass patch that sounded every bit as powerful as any Moog I’ve ever heard.After a year it stopped functioning and I Opened it up and noticed the filter was potted with epoxy to safeguard anyone copying the circuit but also prevents service.I packed it back up and it has been in storage until now.I was considering sending it to discrete synthesizers (CMS) for service but there are quite a few options that would improve upon the existing instrument but I should leave that up to the end user how it should be hot-rodded.This synthesizer will always be worth more than the current Korg or Behringer knock offs because this ARP is 48 years old and is a collector item.I am selling this synth as is, untested but it does turn on and I was able to get a droning sound pitch tracked using the keyboard.” Click here to search for synths on eBay

“Born in 1973, this ARP 2600 set is 46 years young. It has the coveted Moog type (4012) ladder filter.

Complete professional future proofing performed in the fall of 2019. This 2600 received 68 hours of meticulous care by our technician that has over 30 years or ARP / Oberheim / Moog experience.

We have plenty of references on both sides of the Atlantic with several recent $10.000+ machines sold. Buy with confidence.

This 1973 ARP 2600 / ARP 3604-P keyboard is now ready for another 40+ years of spectacular sound and music creation.

It is in stunning operational condition and sounds spectacular!

The ARP 2600 is a very early one (1973) that has the Tonus front panel (square holes for the speakers). All the main boards are the Tonus boards, complete with gold plated connectors and the bettering wiring.

This machine has the highly desired copper clad “Moog” filter (4012) and the larger 17″ reverb tank amongst other perks.

These really early 1970s 2600 benefits from a period when ARP/Tonus were still building them with the best components and that extra love.

Really unique to find a beast like this in this fantastic condition!

All submodules are original modules, no re-manufactured clone modules in this machine.

The ARP 2600 is one of the most legendary analog synths every made.

Everything from crazy sound effects, Earthquake style base lines, beautiful leads and potent kick drums, the 2600 can do it all.

Highlights future proofing:

* All new high-end capacitor power supply upgrade

* New powerful mains transformer to ensure (pitch) stability

* Multi turn high end trimmers on power supply

* All circuit board tantalum’s replaced (critical) with high end capacitors

* New main unit Cinch Jones receptacle (for keyboard connector)

* NOS parts refurbished (keyboard) Cinch Jones connector

* New Reverb tank mounting bushings

ARP 3604P Keyboard for ARP 2600 Synthesizer

“This is the single voice keyboard manufactured originally for v.1 and v.2 series Arp 2600 synthesizers. Unlike old keyboards which are found in attics or forgotten in a basement, this has been an active keyboard in a smoke free studio. The keyboard action has been cleaned and a brand new set of bushings installed last year so it has no clacking or stickie keys. It plays very smooth. All electronic controls function 100%. None of the Tolex covering is ripped, but on the top of the case there are some scratches. It is cosmetically clean but the top of the case is missing the latches and one of the latching hooks as shown in the pictures. I do not wish to do any latch upgrades to the case and would rather that be determined by the new owner. Ships with a 6 pin connecting cable original to the Arp 2600. It will be wrapped and shipped carefully. ”

ARP 3604P

“This is for sale an Arp 3604-P keyboard controller and and a 2600 Arp service manual.

I was negotiating to buy a 2600 Synthesiser last year to use it with though the negotiating fell through after I bought this and am left with it, so am letting it go as I do not intend to look for a 2600 in the foreseeable future.

It was given service a month ago by a local repair tech who gave it a internal clean and check.

I have no way to test it’s intended functions without a 2600 unit and if your looking at using it as such it would be necessary for an appropriate tech to calibrate it with the Synthesiser, and check it as it’s a 70s machine. There is no cable for connecting the 3604-P to the 2600. As such the listing is parts not working.”

“Very good condition, with some wear as expected for its age but overall still nice shape. Most of the wear is on the outside tolex, the front panel face and keyboard itself are in great shape. Includes both lids to unit and keyboard along with keyboard connecting cable. Recently fully serviced by professional tech. We’ve had many 2600s pass through our shop over the years and we found this particular unit to sound fantastic. It’s 100% fully functional, except for 2 small issues worth mentioning: one slider shaft has a broken tip (in Voltage Processor section, probably the least used part of the synth and you still have 2 other working Voltage Processors), and the keyboard input jack to VCO3 is hardwired to receive voltage from the keyboard (jack will not bypass the keyboard input). Other than these two issues the unit is working as it should. At some point this was modified to accept standard 3-prong cable instead of the unusual oval shaped cable they original came with. ”

Selling my ARP 2600 as i need money for a project. The synth was fully serviceds in 2017 by Kent Spong: work included fitting new contacts, springs and bushings to the keyboard, plus general maintenance inc replacing caps and some knobs/switches. I also asked Kent to fit an additional long reverb tank as well as the short and install a toggle switch to alternate between the two. The central position of the switch bypasses both – please see last pictures. The switch can be mounted in the case – but i wanted to keep the 2600 original. so I’ve left this as an option for the potential buyer.

“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.” Click here to search for synths on eBay
