"Vintage (~1980) Oberheim OB-X [8-voice] with Encore MIDI installed!
This has been my personal holy grail analog synth for many years. The deluxe Encore MIDI kit was professionally installed and gives the unit full MIDI in/out/thru capabilities as well as improved OS system and the ability to store 120 factory patches (i.e. OB-Xa). The synth was serviced by a pro tech and working flawlessly until just recently. Currently, there is no audio being sent from the L/R Mono output jacks. The digital processing section appears to be working normally as the knobs and LED switches are still functional (see video demo link). The eight individual voice cards were all calibrated previously and were each in working order."
