If its blown...You think maybe it just heated up but didnt pop. which caused the black on the board when iv seen resistors fry they are black. It looks like the board just got hot or something
LOL. A properly functioning amp doesn't have burned components on the board period. If you're lucky it's simply that it was blown and properly repaired.
On the bright side, if the guy doesn't man up and make it right, send the thing to dB-R for repair and you're still under the cost of a new one for a solid amp.
