Audio Amplifier Circuit Diagram Amplificador Con Transistor 13003. All the cfl bulbs are having two of them. The circuit shown below is not at all expensive as the amplifier contains only an op amp and four transistors easily available from your electronics junk box.
Tda7294 audio amplifier circuits p. This is the circuit diagram of a headphone amplifier operating in the class a push pull mode. The maximum possible efficiency for class a operation is 50 and it further reduces when capacitive coupling is used.
This circuit is designed with very few and minimum components.
Tda7294 audio amplifier circuits p. Following is the schematic of single 13003 npn transistor amplifier. This circuit is designed with very few and minimum components. How to make dual 13003 transistor amplifier using old cfl bulb https www yout.
