FeedbackLoop | #77 - Korg Electribe ER-1 mkII repair fail @feedback-loop | Uploaded 5 years ago | Updated 22 hours ago
This Korg ER-1 had a burned 5V DC-DC converter, which, most probably, killed some other important parts such as the micro-controller, DSP and memory. The DC-DC converter was repaired, but there were no signs of life, and the DSP seems to run too hot. At the moment this looks beyond economical repair.
