I got this MTX Thunder 4160 with a burned out cap, transistor, and a resistor. I got all of the right parts to it but I made a big time mistake of soldering the transistor on backward, I know don't say a thing. So when I powered it up, the amp smoked but only 2 transistors are damage. One I can replace, but the other one, it has one leg that solder won't stick no matter what. I guess the board is too burnt. What could I do to get the solder sticking? Right now I got 2 legs solder but the 3rd leg won't stick with solder. I wonder if it works with just the leg on the board without solder?
Also, I was not careful and burn the outer part of the square white ceramic piece which seem to be a capacitor but no internal part showing, would it still works?
I got photos below guys.
