Re: Blown Talon SR

We had one of our KOP Talon's from this year, that blew about 10 seconds after we turned power on for the first time. We check wiring, all 3 inches of it back to the PDP, was fine. So I decide to look into it, and found that the capacitor was installed backwards.
Capacitors this size have cut marks on the top to open to allow venting in case of over voltage, or reverse voltage. With this capacitor's top up againts the heatsink, these vent couldn't pop up and open, so the cap blew out the side wall.
