ARP 2600 ANALOG Synthesizer with 3620 Keyboard in Chicago, Illinois For Sale

ARP xxxx ANALOG Synthesizer with xxxx Keyboard
Price: $xxxx
For sale is a ARP xxxx Analog Synthesizer with a Model xxxx Keyboard. Both the synth AND the keyboard are Serial Number xxxx (they Match). The instrument is 100% fully functional. I just had it serviced by my tech, who upgraded the power supply to a more stable (modern) unit, tested all modules, and fully cleaned & calibrated everything. This is a mid 70's xxxx. Hard to determine, but VIntage Synthe Explorer denotes this model (gray face) as having the model xxxx filter, and model xxxx and xxxx-1 (National Semiconductor) VCO chips.
The unit is 100% stock with the exception of the upgraded power supply and an IEC power input connector. There is also a u-bracket missing from one of the keyboard case latches. All other latches & handles intact. Keyboard cable and connector is original . EVERYTHING WORKS. It is also in extremely good shape cosmetically, with only minor damage to the tolex inside the synth case cover (minor peeling on one side).
