I was recapping a williams system 6 power supply and put a cap in backwards. Noticed the displays were not working when I powered up. Looking around to see if I had missed a connector I started hearing a hissing sound. I proceeded to stick my head closer to the back box to see where the sound was coming from...BOOM. I was lucky that the cap body held on to the board. Other than needed to change underwear and a ringing in my ears I was ok.
So normally when there is a pair of caps on a board they typically go the same direction....not these. It was late at night and I was not paying close enough attention.
It took me about 30 minutes to clean up all the paper frags from inside the backbox and on the playfield. Its amazing how much paper is inside one little cap.
