I see that the 2 left legs are slightly shorter than the right leg,  but I am sure that there is still enough leg left to be able to reattach that part.  Straighten the bend out of the left leg, clean all 3 holes and reinsert the part and resolder it.

Do you have a multimeter?  If so, set it to the diode test function, and check the 4 larger devices that are mounted to the heat sink.  They are the heat sink mounted devices that are very near the resistor you are working with.  Check from leg 1 to 2, then leg 1 to 3, then leg 2 to 3.  Check each of the 4 transistors, one of them will read very near 0.000.  If you do have one that reads much lower than the others, chances are it is defective.  I am pretty sure they use TIP 35C and TIP 36C.

hello i forgot i had this. i just happened to try to hook this amp up and it still didn't work so i was looking at the posts and was wondering how to test the output transistors to see which ones work and don't i hooked up the ground power and remote and it still went to protect and noticed on a reply that if it still has the problem it will be an easy fix.
