In my latest video, I finish a recap of an ARP Omni 2 for a customer, and find some burned up parts resulting from shorted tantalum capacitors. Getting the tantalum capacitors out of your ARP synths should be considered mandatory maintenance, and can save you from expensive, out-of-production chips getting damaged, like the top octave generator in this video.
