” ARP 2601- The sale includes the synthesizer and matching serial number keyboard, original non copied manuals for synth and keyboard,old 1975 promotional materials, 12 patch cable of different lengths including several glow in the dark cables for live night time use., and dual 1/8″ to 1/4 ” synth to mixer(Amp) cables. This model is the Arp 2601P V1.0 circa 1975 with matching serial number 3620 duo-phonic LFO keyboard..This unit has the 4012 Moog ladder filter which was discontinued in the subsequent 2601P V2.0 model. It is serial number 0087 as is the serial number of the keyboard.This unit is in excellent cosmetic and functional condition for being close to 40 years old and has been brought up to showroom condition within the past year.
When searching for a 2600 , my goal was always to find a unit that had essentially been frozen in a time capsule and then replace dried out electrolytics! This is it. This synth was sequestered for nearly three decades in a closet in Calgary away from indoor lighting and moisture. Until recently, last played in 1978. Consequently, the grey faceplate shows no evidence of any fading .The tolex is original and in good shape..All the 1/8″ input/ outputs and faceplate nuts and screws are like new- shiney silver. Not even a hint of rust on any jack which would be evidence of poor environmental storage and moisture exposure.
In addition to the 12 standard photos, there is a link with 53 higher resolution photos of the synth, keyboard, and tolex cabinets/covers at all possible angles at wwwdotflickrdotcom/photos/ john316_golf ( sorry, have to list the site this way or it will be blocked ).If you are serious about purchasing, you will definitely be reviewing these.
In order to bring this synth up to current standards, the following work was done in 2011 by Davidson Electronics(NY):
All keyboard contacts cleaned, busbars polished, and bushings replaced(action feels great)
All tantalum capacitors were replaced
70% of op-amps were replaced
All sliders lubricated( no scratchy pots)
Additionally, New England Analog in Spring 2014 performed the following work:
replaced the standard 9″ reverb tank with a 17″ reverb spring which matched the original Blue Marvin/ Grey Meanie spring length.
Replaced all voltage regulators
Calibrated the PSU to factory specs
Replaced tantalum decoupling caps on VCO3
installed new high power speakers
Installed new NEA designed VCA module(eliminates the original ARP design VCA “thump”.
installed new headphone jack which is designed to cut out external speakers when in use.
All together, over $2800 of work was done to this synth and you would be hard pressed to find one in similar functional condition with the high quality original cosmetics of this unit .Reason for selling is I just put a 50% deposit on the Schmidt synthesizer and need to raise funds for the other 50%.This was a tough decision.I’ll never find another 2600 down the road that sounds and looks as good as this one.” Link
