This be DC power supply Regulator , that older use 78xx integrated species circuits perform to wait for control the level voltage be stable always. By you have can to fine decorate the pressure follows to want with VR1 follow the circuit.
TDA2030 Bridge amplifier circuit
The TDA2030 Bridge amplifier circuit, power output of 35 watts to 40 watts at 8 ohms speaker. It use dual +15V -15V DC power supply at 2A max. The advantage of it is that we use ICs that are easy to find, small, easy to create without any modifications. View IC TDA2030 must be mounted on heatsink. Can be directly connected to CD players, tuners and tape recorders.
