LOL.... I just fried 3 of my brianGT LM4780 boards
ZAAAAP!!!
fried I have no idea what happened... but I'm glad I only hooked them up one at a time everything's perfect... so with the last 5 boards I have I'm going to be way more careful only one question... the AC1 with a line over it is neutral right??? and the AC1 without a line is the hot wire correct lol jesus can't believe it fried.... it only did this once I hooked the input and outputs up though |

I'm pretty sure just the chips are shot so I can simply salvage the other comps if I so desire

You can kill a pair of speakers. Are you sure you connected the PSU wires in the right way? You didn't reverse the positive with the negative rail? |

I don't think so... I didn't hook up speakers... never even got to that point I'm pretty sure I did but that's why I asked... what is the AC1 with line over it mean on the rectifier board.... the AC1 without it???? and the AC2 etc as far as from the wall to the xfrmer it's right now with hot and cold wires so.... yea I"m pretty damn sure that far is right what would cause the chip casing to explode? on 2 chips... but no other components do anything or even smoke? |
