Synthchaser #087 – Oberheim OB-SX Restoration & Repair

Billed as a preset-only OB-X but sporting nearly identical voice cards to the OB-Xa, the Oberheim OB-SX is a pretty underrated synth. Here I give some love to a long neglected OB-SX by rebuilding the power supply, voice cards, and keybed, and repairing a few other problems I encounter along the way.
