this amp board keep burning t1p4c1 transistor any help would be great think the resistor and the input section may be the problem not correct rating

Re: power speaker board
That TIP41C got mighty toasty. Catastrophic failure usually is caused by catastrophic issues... do you know what happened before it started frying these? This is not the first transistor it fried?
Who made the amplifier? What model is it, perhaps someone can find the schematic.
Else please show a good photo of the tracks on the other side of the board.

Re: power speaker board
reason why I ask is something seems very wrong with the circuit.
Yes the TIP41 is paired with the TIP42 but I would imagine audio amplifiers should be stereo these days and this is not paired with another channel so I don't know what it's doing. Is this a 2.1 amplifier perhaps, still odd the high power transistors are paired and these mere TIP41/TIP42 is not if they go to the LFE.
Also resistors usually do not go short when they fail.
