    My subwoofer got struck by lightning and I am attempting to repair it. It appears two capacitors and the MOSFET chip were destroyed. It appears to be a simple enough fix, but I need help finding the right capacitors and MOSFET chip. Please help!

    It looks like it blew a chip off the epoxy. If you can find it, your cause would be advanced. That chip contains all the important numbers :(

    That's what I was afraid of. The capacitors casings were rolling around inside the subwoofer enclosure, so I was able to get those, but I fear that the MOSFET chip may have vaporized. I will take a closer look tonight though just in-case it blew off as a single piece.
