Hello everyone, here on our Youtube channel K-9 Electronic Recovery. we show you how to make your own homemade audio amplifier, with very few materials. and plenty of power. Output to speakers up to 80 watts RMS, simple voltage from 24 volts DC to 60 DC 5 Amps. It is an idea to amplify the sound of your MP3 player and USB Bluetooth. Also your computer, with some speakers you have at home, such as the speakers of the old mini component, the circuit is very basic, with only 3 bipolar transistors and 4 resistors. You can enjoy a smooth and powerful sound. @k9Recuperacion-g2e @SR-AUDIO-650W @electronicasancheztutorial8205
