Easy To Make Audio Amplifier From Transistor 13003

Transistor 13003 is a familiar component in electronic devices, such as light bulbs, adapters... You can take advantage of it to make an audio amplifier. In the video I used it for a 3W audio amplifier you should use a larger aluminum heatsink. Because the circuit is simple, the power dissipation on the transistor is quite large, you should use a 5V 2A adapter or more. Note: The collector of the two transistors is isolated from each other. ------------------------------------- Thank you to everyone who watched the video.
