OBX Replacement Voice Card Set/DIY


SKU: N/A Categories: , ,


They say necessity is the mother of invention. One day we sold off a lot of original OBX voice cards. We tried some solutions to replace them with other OBX compatible cards but the problem with them was that there’s lots of SMD, lots of (scientifically accurate) replacement parts, and it justĀ doesn’t feel right to stick in a 40 year old masterpiece.

So, we went ahead and invested into perfect 1:1 replicas of the original voice cards with the gate LED. This means just like the originals they fit antiquated components and trim pots, have no silk screen, use a copper layer for component orientation and positions, have curvy lines for traces, and require patience to assemble.

We figured that if we were to make new OBX cards, they had to be JUST like the originals. No straight modern day traces and cute little vias. The copper layer is identical to the original, so if somehow some mojo of the sound was in that aspect, it’s all there.

These come in a few ways:

  1. Blank cards with our without components
  2. Assembled cards
  3. Assembled sets

Coming soon:

  1. Mother boards
  2. 4-voice expansion tray + motherboard

All parts for theseĀ are available. Building out one card isn’t a very expensive endeavor if you want to do it yourself.
