via the listing: "RA MOOG modular synthesizer system built in 1969. This 1p/2p custom system built especially for Rick Powell in 1969.
Rick was a musician, a producer and a close friend of Robert Moog.
This is one of only a few completely intact RA Moog factory built custom systems specifically built for a customer during the RA Moog period.
Rick Powell used this unit on his “Choir Book” LP (also featured on LP cover) and also the “Switched On Country” LP.
System was built with a RA Moog 950 keyboard (serial 2048) which is in very good condition. The modules are as shown. 4 of the 902 voltage controller amplifiers, 2 of the 911 envelope generators, a 907 fixed filter bank, a 904-A voltage controlled low pass filter, a 904-B voltage controlled high pass filter, a 901-A oscillator controller, a 901-B oscillator, a 903 white sound source, a 901 voltage controlled oscillator and 2 of the mixer units. Both keyboard and cabinet interconnect cables are included. The 901 has a common factory mod to regulate thermal changes which cause drift.
I Bought this unit directly from Rick Powell’s widow and drove cross country from Los Angeles to Florida to pick it up. I wanted to avoid shipping it. Months later I drove it cross country again to Georgia to drop it off with Phil Cirocco of C.M.S. Phil Cirocco at C.M.S. is by far the most knowledgeable, talented, experienced and careful modular synthesizer technician in the world. Though I requested Phil restore the unit meticulously at to factory operating spec, I also insisted the entire system remain as factory stock as possible and all replaced electronic parts be in harmony with the original production parts. A great deal of Phil’s time was used to make this system as perfect as possible and operating to original factory spec. The bill for servicing was a substantial investment. At the time of servicing I had planned to keep this unit and spared no expense. Recently however I was fortunate to have the opportunity to purchase a more desirable system and so I will let this beautiful perfectly restored system go to a new home.
This is a very rare chance to own an original RA Moog factory assembled unit with interesting provenance. It is also a rare chance to own a Moog system so expertly and carefully electronically restored."
