Oberheim DSX Project Machine

“Vintage Oberheim DSX Digital Polyphonic Sequencer. Shipped with USPS Parcel Select Ground.

no cables included

The main circuit board shows some corrosion (see pictures). The Capacitors were tested to be good, but the battery only showed .1V,

All buttons on the interface and the display were tested and were good (I plugged in the interface board into a working unit to test). So it appears that the problem is with the main board. Not sure it can be fixed. May be better off used for parts as the control board is in great shape.

Version 2 board.

Please note the scratch between the D and the X on the cover.”

“My DSX is in fantastic condition both cosmetically and functionally. I had the battery replaced this month. Please feel free to ask questions.

Oberheim DSX

“Appears to power up and work fine. I don’t have another Oberheim synth to connect it to so I’m unable to test it. Was told it works fine. See photos of inside. Some corrosion near caps at front of bottom PCB. Power cord not included (it’s just a regular PC cable).

When you turn it on it says “CONNECT SYNTH” based on some googling that means it’s version 2.X or lower.” Click here to search for synths on eBay

Oberheim DSX

“Greetings; I’m offering up my Oberheim DSX Sequencer. It comes complete with the foot switch, volume pedal, power cord, and interface cable. This DSX has been stored in a closet at my home for many years. It is in excellent condition for its age. I sold my OBXa many years ago, so I have no way of testing it properly. The DSX worked well with my Obie before I stored it, which was 10+ years ago. My OBXa had the MIDI conversion, so I didn’t use it too much….(I was using a Roland MC-80). I’m not sure if it needs to be serviced, but the battery will most likely need replacement. I will include the instructions if I can ind them. I’m not too far from most of SoCal if you would like to arrange for pick-up”
