I always thought the old saying was "Fun first, safety second." No need for details, but the incident involved sparks, blowing up a tool, and not wearing safety glasses. Now I think that safety comes first and a half.
The bottom right part of the power board takes in power from the small city and does some magic that I don't understand and passes out DC voltages to the other boards in the cabinet (you can see three groups of output wires). The actual DC output that I'm getting is closer to completely wrong than nearly right. Here is the power board:
All of the capacitors (technical name: round thingies) are going to get replaced, except for the big banana capacitor. Hopefully by replacing them, the DC output will be closer to almost right than mostly wrong. The order for capacitors has been placed so now all I can do is wait. There are probably other things I could be doing, but I'd rather just stand completely still for days and just wait.
