Posted in Musical Hacks Tagged Burned, capacitor, Cooked, JBL, PCB repair, Smoked Post navigation If you’re a big fan of burned PCB’s, check out Hackaday Prize Judge Dave Jones latest EEVblog video, where he works on a Ness home alarm panel with a similarly cooked section of FR4. After soldering in some new high quality capacitors, the amplifier was back in action! soldered the traces across the join with small sections of wire and solder wick.

The amplifier and patch were milled and sanded to match up nearly perfectly. used this image to etch a small patch board. Some careful Photoshop work resulted in an image of the section of PCB to be repaired. Amazingly, the manual included a board layout with traces. The result was a rather large hole in the middle of an otherwise serviceable board. Charred PCB is conductive, so anything black had to be cut out. Not he took on the most extreme PCB repair we’ve seen in a long time.Īfter removing the offending caps and a few other components, got a good look at the damage. Most of us would have cut our losses and bought a new setup.

The amplifier board however, had seen better days. house, possessions, and subwoofer enclosure were all safe. Thankfully the flames were contained to the amplifier board.

The electrolyte then caused a short in the mains AC section of the board, resulting in a flare up. Four of the large capacitors on the board had bulged and leaked. His JBL L8400P 600 watt subwoofer went up in flames – literally.
