Way Back in highschool, we convinced one of our friends who was selling drugs to pony up $300 for a used B52 speaker system, so we could throw raves (and he could sell more drugs.) Hes long since moved on, but we still have that b52 unit, and still use it for events.
20 years ago, a couple hours before one such event, the system was dead. I pulled off the cover, and found a scorched up resistor. I took a penny, soldered one of the clipped off leads to the edge of it, then with a multimeter, slowly dragged across the surface, until I found a point with the correct resistance value. I soldered the other lead on at that point, soldered the penny into the board, and its still working to this day!
