[xsdb] had a real problem. His JBL L8400P 600 watt subwoofer went up in
flames ? literally. Four of the large capacitors on the board had bulged
and leaked. The electrolyte then caused a short in the mains AC section
of the board, resulting in a flare up. Thankfully the flames were
contained to the amplifier board. [xsdb's] house, possessions, and
subwoofer enclosure were all safe. The amplifier board however, had seen
better days. Most of us would have cut our losses and bought a new
setup. Not [xsdb] he took on the most extreme PCB repair we've seen in a
long time.

I wouldn't quite call this extreme...
