For simplicity, good performance, and reasonable cost, an unregulated supply is the most common for an audio power amplifier. An unregulated supply uses a transformer, a bridge rectifier, and various rail capacitors. A draw back to the unregulated supply is the voltage fluctuations with load and power mains fluctuations.
