Danny,
Unless the unit is under warranty, I'm going to guess that you're going to pay about $200 for the repair, which is almost half the price of the unit. That would be 2-3 hours of labor and parts at something like this:

Fast turnaround and rush services available!
Normal turnaround is 5-7 business days...
Rate: $85.00 Per Hour (Rush Fee: $50)

That's American Music here in Seattle. Parts are extra. Power transistors aren't usually *that* much, a few dollars a piece, when you figure mark up, but you could easily be looking at $50 for those.

So, be prepared. You'll have a working amp that may or may not last 30 minutes at the next gig, or last four years. Who knows. "Ya pays your money and takes ya chances!" Most places will have a 30 or 90 day warranty on their work, but that's not real reassuring when you've paid out $200+ and have the same issue six months later on the other channel.

I'm blessed watching God do what He does best. I've had a few rough years, and I'm still not back to where I want to be, but I'm on the way and things are looking far better now than what they were!
