Do you love music? Imagine we can build power amplifiers system. Sound good, doesn’t it? Here are many circuits. For example, about Audio amplifiers, bridge amplifier, Using transistor or IC or MOSFET, Mixer, Graphic Equalizer, Preamplifiers. And, Sound generators, tone controls, Melodies, Sirens, Animal sound, effect voices. Even, Burglar alarm, and more. I cannot explain to you all. But sure I do not like to see you miss them.
