Including service report
Oberheim CPS-1 (synthesizer expander module) and CPS-2 (mini sequencer) cases available for sale, without the modules. The psu boards are just been serviced. Notice that a pro tech with knowledge of vintage synths has to install the modules if you have them.
Cosmetically both units are in used condition. Please check the photos for a good overall impression. The CPS-2 is missing one rubber foot. The CPS-1 is working on 117v. The CPS-2 is working on 105 - 125v. Both units have a Japanese plug installed.
