Thanks Jerry, interesting and informative - I was using the latest 027 firmware, by the way.?
The event happened when I nudged the rig and the power cable. While that seems to have been the issue, I also had speaker ?and key cables plugged in - so I can’t rule out that the little board for these connectors might have shorted against the case (the clearance there was less than it should be due to a small gap between it and the main board). Yes - builder error - while soldering the board I allowed some solder to flow between the boards causing a small gap.?
?
All that said - if it’s just one very inexpensive zener which is easy to replace…
