via this auction

"47 years young! ☆☆☆☆☆ ARP 2600 Tonus serial#26343- complete set.

Complete professional future proofing performed in the spring of 2019.
This 2600 received 74 hours of meticulous care by our technician that has over 30 years or ARP / Oberheim / Moog experience.

This 1972 Tonus / ARP 2600 and Tonus / ARP 3604-P keyboard is now ready for another 40+ years of spectacular sound and music creation.

It is in stunning operational and visual condition and even better, it sounds spectacular!

The Tonus generation is a highly desired generation of the 2600. It contains the copper clad "Moog" filter (4012), the rare coveted 4027 oscillators and the larger 17" reverb tank amongst other perks.

These really early 1970s 2600 benefits from a period when ARP/Tonus were still building them with the best components and that extra love.

Really unique to find a beast like this in this fantastic condition!

All submodules are original modules, no re-manufactured clone modules in this original machine.

The ARP 2600 is one of the most legendary analog synths every made.

Everything from crazy sound effects, Earthquake style base lines, beautiful leads and potent kick drums, the 2600 can do it all.
