"Rare, early ARP 2500 modular synthesizer in very good cosmetic condition and working 100%. A friend of mine bought this one from Phil Cirocco of CMS/Discrete Synthesizers in late 2007 and it's still working solid. As you can see, this is an earlier 2002 cabinet with a 3000 series keyboard.
It includes the following modules-
1002 Power Control
1003 Dual Envelope Generator
1005 Ring Mod / VCA
1006 Lowpass filter / VCA
1016 Noise / Random Voltage
1023 Dual VCO
1027 3 x 10 Sequencer
1033 Dual EG with delay
1036 Dual S/H, Clock
1047 Multimode Filter"
Cosmetically- The veneer on the cabinet does have some chipping here and there, but overall it still looks very good. Some of the modules have a former owners name and the serial # etched in on the corners.
Internally- According to Phil's description when he sold it, the power supply had been upgraded about 2 years prior to my friend buying it to a 1.5 Amp, low noise high performance unit. The separate 12v lamp power supply had also been rebuilt around that time.
The keyboard works great as well as all of the knobs, switches, matrix sliders, etc. No scratchy pots whatsoever! Phil obviously took care of this thing. I did notice that one of the LEDs on the sequencer has since burned out, but if this is an issue I can have it replaced.
This is not a plug in and play unit like an Arp 2600. Patching is required if you want sound. Please be aware of this."
