Quoted from Mach5Amps:
Flippy-flapping. Wiggle-waggling. In and out, free and loose, like a... Wait. I don't think I'm allowed to say that.
Disappointed. But, I can't wait to fix it, so I can play again. Cause it's awesome.
If you don't have the coil sleeve on hand, you can borrow one off a lower playfield flipper from that AC/DC and just avoid playing the "hell" themed songs that activates the lower playfield. That'll get you back in business and able to play about 3/4 of the songs.
