The link you provided does not work. Nevertheless, no one can properly diagnose your problem over the Internet just by looking at pictures. You need to have a technician check your amp out thoroughly. Any number of components in your amp could have been burnt out by the turn-on surge when your household power came back. I understand that you were cheated by some unscrupulous technician in the past but you need to put that behind you. Life has its ups and downs and you have to take chances. If ever your power goes out again, unplug and/or turn off all electrical equipment in the home.

What part of the world do you live in? The parts you have pointed to are a pair of 1/4w resistors, and the main output transistor for the "left" channel, based on convention. Typically the base resistor is only a couple of ohms, and once the power transistor it is connected to becomes a short, they quickly overheat. The protection circuit may activate to shut of BOTH channels, but perhaps only one channel is damaged. Labor to perform the rebuild will likely be a couple of hours at $60-$100 per hour, and parts will run up to about $50, assuming they are limited to that one channel. The only hiccup can be "house marked" transistors, which become difficult to cross reference without help from the original manufacturer.

Glen B is right that there could be hidden surprises and damage to other areas that could drive the cost up, but if what you have described seems the extent of it, it should run about $250 to fix.

Hope that helps...
