Is the source according to the amperes that the integrated one needs?

Yes. I already desolded it and tried again on protoboard and it seems that the amplifier was damaged, I will replace it with the tda7377 that is more powerful

Jonathan, in fact, the first time I plugged it in, turn the source upside down and the capacitor that is in parallel warmed up, what I am doing right now is taking out the amplifier and testing it on protoboard to verify if the problem is the amplifier or components, I hope they are the components.

Check that way, but if the overheating capacitor, like mine overheating when that error occurred, that melted the plastic and all the safest is that this bad, in fact when I happen to connect the source to the reverse, end up overheating and damaging that capacitor, a resistance of 300ohm 3w and 2 zener diodes of 12v in the preaudio, also check the other components carefully
