What are the common cause of short circuit in a simple audio amplifier?

Common causes of short circuits in a simple audio amplifier include faulty components such as damaged transistors, capacitors, or resistors that can create unintended pathways for current. Poor solder joints or loose connections may also lead to short circuits, as they can allow wires to touch each other inappropriately. Additionally, overheating due to excessive power draw or incorrect power supply voltage can damage parts and result in shorts. Lastly, external factors like moisture or debris can compromise insulation and cause shorts in the circuit.
