ARP 2600 Analog Synthesizer Meticulously Refurbished



via this auction

"This unit was disassembled, cleaned inside and out, meticulously serviced, with some future-proofing measures and fully and repeatedly tested by vintage synth specialists with decades of experience (us). This process required 22 hours of skilled labor. The result is an ARP 2601 that is much better than the rest. Don't settle for less / get what you pay for.

This unit is working perfect, is ready to play, and will hopefully outlast all others.

This unit came to us without a keyboard, which is no problem for most people because it's better to control it with an external midi to CV converter. This way, it can be played by your MIDI DAW or whatever midi controller you use with it. If you need an original arp 2600 keyboard to go with it, we have a model 3604 that we can sell you - email us.


In addition to any repairs, we did the following work to this unit:

-Fully disassembled, cleaned inside and out.
-Power supply rebuilt: new capacitors and trimpots.
-All tantalum capacitors replaced (these are a common source of failure in ARPs).
-All sliders and switches cleaned and lubricated.
-Cleaned Cinch-Jones connectors.
-Recalibrated.
-Multiple systematic tests of all functions.

Earlier revisions of the 2600 are notorious for having their modules sealed in black epoxy. This late version 2601's circuits are all open, so if a component ever goes bad, repair should be easy."
