This ARP 2600P with 3620 keyboard had 1 owner before me. It was purchased around 1974, gently used, then packed away in storage in 1986. It hasn't been used since then. It is in perfect condition, and looks brand new with no surface scratches or cosmetic blemishes on the panel. Everything is original. The tolex is 9/10, with only minor fraying, but it doesn't have the ARP Synthesizer badge on the outside. The original owner had a padlock installed, and there are holes on the top for the screws. It comes with both lids for the 2600 and 3620 as well as original paperwork from ARP, some patch cables, and original ARP footswitch. Everyone who's seen it agrees that its in brand new condition, and a real museum piece.
It would be perfect for Congresswoman Ilhan Omar, since she asked for one! 

It sounds phenomenal, and the speakers are really helpful for standalone operation. The 4012 filter is gorgeous and overdrives nicely. The oscillators beat against each other and feed the filter unlike anything I've ever heard. The spring reverb really makes it stereo and wide. The oscillators maintain tuning and scaling across the octaves. I found it best to play with external sequencer and eurorack gear. It is inspiring, to say the least. 

I took it to a local technician who did the following updates: 
- Full resolder of all PCB's
- Clean up of excessive flux
- Resolder of wire connections on case connectors
- Cleaned contacts on keyboard cable and case connector
- Rebuild of the power supply
     - Replace all electrolytic caps in power supply
     - Clean and reapply all old thermal paste on regulator transistors
- Repaired non functioning ring modulation circuit
- Repaired non functioning electronic switch circuit
- Cleaned and lubricated all slide pots on main unit
- Removed all slide pots from keyboard unit and did a teardown and recleaning/lubrication
- Removed all keys from keyboard and replaced all rubber bushings
- Cleaned all key contacts
- Readjusted all key contacts (as best as they could)
- Full recalibration of both main and keyboard units

Shipping: This will be professionally packed and insured for the full amount. If you are near Denver, I would consider meeting you halfway and handing it off.
