Question about Onkyo TX-DS747

Crossed speaker wires...did I destroy my amp?

So i'm an idiot and while moving a speaker around, I accidentally touched the + and - leads of my center channel to a metal plate while my receiver was on and playing music. In other words, the speaker cable was disconnected from the speaker and the + and - leads touched each other while the amplifier was on. White smoke comes out of my receiver if I turn it on within 5 seconds. Is there any hope of repair, or should I look into replacing the amp? How much might it cost to repair this sort of thing? Thanks in advance!

Re: Crossed speaker wires...did I destroy my amp?

Most likely what you did was burn out the output transistors to the center channel. and probably the Bias resistors that control them. The parts themselves would be inexpensive. But they would probably have to come straight from Onkyo. And you would have to know there part number. And to get matched complimentaries. Mark up. And how far into the circuit the damage went. If I was to repair it I would probably put $100 to $125. But depending on the age of the unit and what a new won would cost is what I would use to decide to replace or restore.
