ARP 2500 Modular Synthesizer

via this auction

"Matrix working and sliders are moving smooth, just like you would expect.

All modules have their Matrix slidercaps, only the blank panels don't. This system requires 110V so the buyer has to use a voltage converter, if the system stays in Europe or if it goes to Australia. Rest of the world is 110V, so no voltage converter needed. This system has serial#75-023. So this one was built in the year 1972.The cabinet is complete metall with wood attached to the sides. The modules in this system are: Dual VCO 1023, Osc 1004-T, Dual Noise/Random Voltage Generator 1016, Dual Envelope 1033, Multimode Filter 1047, Dual Envelope 1033, FiltAmp 1006, Dual Envelope 1003a, ModAmp 1005, Multimode Filter 1047, Power Control 1002. The system does not have a keyboard,but it does have a midi kit installed by a professional, the midi is from Doepfer, model MCV-8. So as this system has midi,you can use any midi controller, or the good old cv/gate."
