One of these Mackie speakers
One of these Mackie speakers did not power up. The problem was traced to a pair of power diodes in a TO-220 package that had two pins broken off. I am quite puzzled as to how this happened. Perhaps, the speaker was dropped, and the board flexed so much due to relatively heavy transformer. Strange things happen.
