ARP 2500

"super-rare ARP 2500 from the personal collection of Phil Cirocco of CMS / Discrete Synthesizers. It features a rare, vintage ARP 2002 cabinet, a 3000 series four voice keyboard and a full compliment of 1000 series modules. 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. The 2002 cabinet is in good condition. It is all original and has not been restored. It was made in 1970. It is a very early and rare version featuring 10 patching tracks on the top section instead of the 20 that later versions use. The top section of a 2500 is only used for CV, gate and trigger etc. so 10 tracks is usually adequate for most situations. It has 20 tracks on the bottom as all 2500s do. Also, this early unit is more compact and uses its space more efficiently than later versions. (Many people complain about the large amount of real estate that later version 2500 cabinets use up.) The power supply was upgraded here at CMS about 2 years ago to a 1.5 Amp, low noise high performance unit. The separate 12v lamp power supply was also recently rebuilt. The Keyboard is a standard ARP 2500 4 voice split keyboard. The rubber mounts of the key contact PCB have been replaced. The key contacts have been cleaned. The rubber pads of the keyboard are intact. The keyboard is fully functional. The keys are in very good condition. The hardwood keyboard cabinet is in very good condition. There is a very small ding on the left keyboard control panel. It includes the keyboard connection cables as well as the AC cable. The 1000 series modules are fully functional and have been meticulously maintained here at CMS for the past decade. The module compliment includes the legendary ARP 1047 Multimode Filter and the ARP 1027 sequencer. The 1004T VCO and the 1036 Dual Sample Hold were originally owned by the ARP factory as production samples. The dual VCO is a super-rare prototype developed at ARP by Roger Powell and Clark Ferguson.

Several modules have a former owners name and serial # engraved the corners of the front panels. The veneer cabinet has 2 corners that have been rounded slightly, but they are in the back. The left side has some broken veneer on the front edge. I was planning to refinish the cabinet myself, but I never got around to it. It’s quite easy to separate the electronics from the cabinet. When all the modules are out of the case, the matrix switch/shelf assembly slides right out the back. The upper left matrix switch assembly looks like it took a small impact at one time, but it functions normally. This is a vintage instrument from 1970"
