Here the circuit diagram of 50W power amplifier. The amplifier uses a pair of power transistors that are MJ2955 and 2N3055 to amplify the input signal. You must use a heatsink on those transistors. The below design diagram uses for single input/output channel, just built two similar circuit to make it dual channel (stereo).

Power Supply Circuit:
This amplifier require dual polarity output power supply (+, ground and -). Use this power supply circuit:
Transformer: 3-5 Ampere, 24V secondary output
Diode: Diode bridge 5A or 4 piece of single diode 5A

vrement jai vous aime baucoups avec de bell schema
is it really 4,700uF for each capacitor in the power supply circuit?
yes, it is
uki uki
is best amplifier from simple power amplifier
