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 just 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 via’s. 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 parts
  2. Assembled cards
  3. Assembled sets

Coming soon:

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


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

Please note:
Assembled cards are assembled by hand by real life humans at our location in Burbank California. Assembled cards don’t ship out right away and are made to order and then tested. Patience is critical! These aren’t on amazon prime for a reason!
DIY kits usually ship in 2-5 days of order. As above, the parts are hand curated and bagged for your self assembly.
Note: As of 9/2020 we are no longer offering DIY kits that include the resistors. This is because it takes way way too long to pack and label each resistor value set. So, the DIY set now includes all IC’s and parts -except- resistors. A mouser cart for all resistors is provided upon purchase so that a robot may do the job for free instead of expensive humans :). This also means DIY kits will now ship out a bit faster.
