This is the circuit diagram of??50W power amplifier based on audio power amplifier IC STK-1050. Symmetrical power supply used to operate this circuit with maximum voltage rated at 53V and recommended supply is 36V. This is a single channel (mono) amplifier circuit, for stereo audio system, you should build two similar circuit. Power supply with minimum 3A center tap transformer should be used for stereo amplifier.
Symmetrical power supply:
This is the sample of symmetrical / dual polarity power supply circuit diagram:
