“Oberheim Matrix-6 Synthesizer
Original owner, purchased new in 1986 and maintained by owner. Good condition, but hasn’t been played regularly in recent years. Replaced backup memory battery, put new caps in power supply. Checked basic functions, MIDI in/out, external program load, keyboard, front panel settings – all appear to be operational. Passes calibration routine with no errors. Checked DAC and HFO calibration with meter and scope. This synthesizer does have some wear and tear. In the mid 90’s the main board was damaged by an electrical surge which required repairing a trace and replacing the EPROM, micro, and memory. The low C key cracked during a move and was repaired with lexan bracing under the key. The repair is visible but the key is solid. There is a custom port (plugged) next the headphone jack that was used for a custom breath controller board add-on. This board has been removed from the synth. See photos. The synthesizer has not had any problems since. Selling as-is. Keep it going for another 30 years. This package includes:
