Headphone Amplifier Circuit using Transistors
Headphone Amplifier Circuit using Transistors make weak sound strong so headphones work well. This circuit is useful when sound is direct from source which is not loud or clear. In this post we talk about small 3V transistor amplifier for better sound. Circuit Working: Parts List: Component Type Value/Specification Quantity Resistors (All resistors are 1/4 […]
Temperature Controlled Fan Circuit for Audio Amplifiers
Amplifiers make heat when working. Too much of heat make it work bad and can die soon. This Temperature Controlled Fan Circuit for Audio Amplifiers keep amplifier cool. Fan starts only when amplifier is hot. If volume is low and less heat then fan stays OFF and saves power. The circuit is made with LM311 […]
