Power Supply Voltage +25V/-25V 2A.
Output 8 OHM Speaker.
Today have Older power Amplifier OCL Circuit come to give friends get see in rows the way again. By it has the electric power about 35W at 8ohm loudspeakers and use Voltage Supply +25V and -25V at Current 2A. Which cheap systematize the sound is Class AB. By this circuit use the integrated circuit number NE540 replace the transistor has many. Then use power Transistor 2N3055 and MJ2955 at output. The detail is other invite a friend has seen in the circuit , be lucky sir.
