A simple 1 watt audio amplifier. The solderless breadboard makes it easy to experiment with additions to the radio circuit. In this section, we will build a simple amplifier, so that a whole room can hear the radio through a speaker. Our amplifier will not be ear shattering, since we have made it as simple as we can to build, but the output is pretty impressive for a single transistor.

For the remainder of the circuit (a simple unit-gain summing network) we have chosen an LM358 op-amp, which is a low-power device that can be operated from a single voltage supply, therefore appropriate for battery-operated circuits. Low-power op-amps draw very little quiescent current and hence help prolong the life of the battery. The LM358 is a

Connect the speaker to LS1 terminals on the board and a 12V battery to the power supply terminals CON1. You may connect a 10-kilo-ohm potentiometer (pot) as volume control at input of the amplifier. To test the amplifier, take a small metal screwdriver and gently touch at input of the amplifier.

Trimmer P1 is for adjusting input power. P1 is not necessary. Capacitor C1 is for filtering DC current out from audio signal. With resistors R1 and R2 we set voltage divider. With voltage divider we set working point of amplifier to half of the supplied voltage (4,5 V in this case). Resistor R3 and trimmer P2 are there to set amplifiers gain.
