Vintage Synth Repair

Hi guys,

after some time of leaving my OB-SX aside I came back to it and realized that the late model that I posess
has different voice cards. I did get some voice cards, but they were the old ones with only 4 pins for power, but the 56 preset and pinstripe model needs the cards with 5 pins for power.

I did bend the extra pin aside and this somehow works, but is no final solution.

Any of you guys have some spare MK III voice cards to sell or swap for the old ones ?
Don't need the CEMs, have them already.

Thanks and best,

Thomas

Yes I have a few later OB-SX voice cards available. Email me on my web page.
