Probably, it's normal? I have several hypex modules and all are warm even when there is no sound.

With the Output Transistors in the circuit, the Emitter resistors burn trough.

It kinda works at least for a short time.

So Im thinking that maybe i need to match the transistors or something like this.

The resistors have the correct value, i used the correct transistors to replace (A1015, C1815) and without the Transistors in the circuit the Voltages match.
