    Icon33 MTX 4160 Amp repair suggestions.

    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.
    Thanks.

    You mean to sand the actual leg on the little transistor itself? Then put flux on the leg? Or flux on the board? As far as heat, what's the temp I should be at? I tried range 365C - 425C and none would stick.
    Thanks.

    yea sand the leg then use flux. i would run wire instead of trying to use those burnt traces.

    Thanks. But the problem is the burnt area is so dark I can't even see the trace. The trace must be really tiny. MTX does not release the schematic diagrams.

    clean it up real good and see how much trace you have left to solder to.
