A 4 Watt Amplifier Portable Radio Circuit Diagram Design using TDA1011

The following schematic depicts the design of a 4 Watt Amplifier Circuit Diagram for portable radio application using TDA1011 from Philips Semiconductor. The device is especially designed for portable radio and recorder applications and delivers up to 4 W in a 4 ? load impedance. List of electronics components are as follows: C1 = 1 Micro Farad, C2 = 1 Micro Farad, C3 = 100 Pico Farad.

Simple Op-Amp Radio Circuit Diagram

The following schematic shows the Simple Op-Amp Radio Circuit Diagram taken from bowdenshobbycircuits.info. This Simple Op-Amp Radio is basically a crystal radio with an audio amplifier. It uses germanium diode (1N34A type). The circuit draws about 10 mA from a 9 volt source.
