"early version ARP 2600 from the personal collection of Phil Cirocco of CMS / Discrete Synthesizers. It features a rare, vintage ARP 2600P V2.0 console and a 3604P keyboard. This is a once in a lifetime opportunity to own a fully functional, killer sounding synthesizer, as well as a rare piece of electronic music history.
This is an early version of the 2600P. It was made in early November of 1971. It is in excellent cosmetic condition. The tolex on the console, as well as the keyboard is in excellent condition - rare for such an early model. The serial number is valid and accurate. It features all original, early type ARP sub-modules. It uses an original ARP 4012 filter. All 3 VCO’s are the great sounding 4027 type. It has the rare, early version 4010 VCA. Since it is a version 2.0, it uses the LM301 op amp for the audio path. However, the op amps are the better sounding military can version. It also uses the original large reverb tank. All of these things combine to form "one great looking and sounding ARP 2600!" To view a production timeline go to:

The outside of the 2600P console is in very good condition. The lid for the console is also in good condition. All of the chrome latches and corners are present and intact. The Tolex on the inner section is in good condition. There are some tears in the Tolex around the front panel that have been repaired. The front panel is in very good condition except for some small unevenness in the corner of the preamp section. This is probably from some hack trying to open the console incorrectly. The preamp itself has been checked out and is totally functional. There are some small scratches in the paint near the right speaker – see photo. There are also some light scratches around the sliders in the voltage processor section. The front panel has not been drilled or modified in any way. Remarkably, the silkscreen shows no signs of wear and is totally intact. The silkscreen is the more beautiful and complex, early type.
This unit also features all new “Switchcraft” chrome front panel hardware! All the sliders are intact and are fully functional. The original black slider caps were not present when I purchased the unit, so I was forced to replace them with other ARP caps. These caps are original ARP equipment and are very rare and expensive.
It includes the keyboard connection cable as well as the AC cable. The keyboard connector on the 2600 console is brand new. The keyboard connection cable is brand new.
The 3604P keyboard is from the same era. It is in brand new condition and is fully functional. The lid for the keyboard is also in perfect condition. The Tolex covering on the keyboard is in perfect condition. The keys are also in perfect condition. The front panel is in very good condition except for some paint chips near the portamento knob. The keyboard has been meticulously maintained here at CMS for the last 15 years.
This system has been fully calibrated recently here at CMS. It holds pitch and scale regardless of temperature from initial start up to running for 8 hours. With no modifications, it can easily be run from a MIDI converter box and MIDI keyboard instead of the ARP keyboard. For more info on this see:
