"For sale is a beautiful 1983 Sequential Circuits Prophet 5 synthesizer, serial number 5604, with midi. Based on info found in the user manual, as well as the external configuration of the unit (as shown in the photos above) this Prophet 5 is a revision 3. More specifically, the serial number indicates that it is a revision 3.3, indicating that it has 120 factory programs, versus the 40 programs found in earlier revisions. I had it serviced recently by Sequential Circuits expert technician Greg Montalbano of Oakland, CA, and he was very impressed by its condition. (Note: on a couple discussion boards I have seen Greg's last named stated as Klosmon, but I think that is only because his email address begins with the term klosmon. I believe I am correct about his last name being Montalbano, however. As of today, my Prophet 5 is in mint condition functionally (thanks to Greg's fine work), and near-mint condition cosmetically. You might be able to find a Prophet 5 for less money, but I can guarantee that it won't be as nice as mine. Below is a list of the tasks that Greg performed back in January 2014:
(1) pots, switches, key contacts cleaned. (2) bypass capacitors replaced on all boards.
(3) factory patches reloaded. (4) synth tuned and scaled. (5) factory midi installed.
(6) new battery installed. (7) keys and wood trim thoroughly cleaned."
"Recently serviced everything works well, stays in tune over many octaves, and sounds great. The keyboard bushings are original. 
"Up for sale is a (1) Nord Micro Modular vocoder panel. It seems to be original, but we've never seen it before. There's a Mic-amp (Version 0.3) installed on it and it's working fine. The yellow jack cable goes to the analog input of the Nord Micro Modular synthesizer. Optical it's in near mint condition with only some small scratches on it. We deliver it with an original psu adaptor to feed the mic-amp. From the mic-amp there's a power cord to feed the Micro Modular."

"Yamaha DX7 II FD synthesizer (with all of the trimmings!) workstation with the Grey Matter Response E! expansion board installed. This DX7 II FD is in excellent shape. All the keys work and look perfect.
