LM317 2N3055 3A Variable power supply | ElecCircuit.com
If you need 3A power supply. We recommend the LM317 adjustable voltage regulator circuit. It use normally component LM317 popular DC voltage regulator and 2N3055 transistor to boost up current to maximum 3A. We can select voltage adjust voltage in steps 3V, 6V, 9V, 12V. adjust continuous 1.25V to 20V. Learn more now!
12V Car Audio amplifier circuit, 50W - 65W with PCB - ElecCircuit.com
This is a car 12V audio amplifier circuit that has high power over than 50w Using the IC TDA1562Q Philips. Which It uses just 12v 50w audio amplifier only. But provide higher watt power to 54 Wrms at load speaker 4 ohms and there is distortion at 1% and watt power maximum 65 Vrms at distortion 10%.
