“Really nice vintage Orange & Black late model ARP 2600 with the 3620 Duophonic keyboard. This particular synthesizer is in great shape and was on display at NAMM 2020. The keyboard controller was serviced by Synthchaser in 2020 and the main unit was tested and calibrated by Synthchaser in February 2025.
There are some scratchy sliders on the main unit, and the tolex inside the main unit’s lid is coming up on one edge (can easily be re-glued). Includes an original style oval power cord.” Click here to visit listing on eBay
