Mini audio Amplifier for tuner or simple receiver.

This mini circuit, can amplify your tuner or simple receiver.
when your radio tuner or simple receiver combined with this circuit, maybe its can make a compact receiver.
the active component is LM386, popular use in many project kit.
actually IC LM386 can run with 4 or 5 Volt voltage, its why LM386 its popular for low voltage amplifier application.
output can be single earphone or speaker with impedance minimum 8 ohm, the result is more better when attached to more high impedance earphone (max 150 ohm).
