Yes, that is my OB-Xa. :)

"Today I'm repairing an OB-Xa for Matrix of matrixsynth.com. One voice card is dead, and others are failing autotune and sounding really inconsistent from voice to voice. In this video we take a look at the state of the synth, and troubleshoot and repair the dead voice card.

Parts used in this video series are available at my website. I also repair and restore Oberheims and other vintage synths for customers around the world."
