Here is another mini circuit project. You can comment here if get something wrong with this electronic schematic design

Here is a simple amplifier for boosting the audio level from low-power sound cards or other audio sources driving small speakers like toys or small transistor radios. The two 2.2 ohm resistors may be replaced with one 3.9 ohm resistor in either emitter.
