TDA2030 transistor amplifier circuit with PCB
Relatively easy to build up to 30W Amp OTL by TDA2030 transistor is packed into this project.the power dissipation of 20W at 8 ohm or 30W at load 4 ohm
TIP41
Power Supply Splitter circuit using op-amp
If you need a dual power supply. But you only have a single supply source. So should build this power supply splitter circuit.
