Product Description


    Our kit 17 - LM386 amplifier - has been a great success.ᅠ However, unless you have a signal of sufficient amplitude it will not produce its maximum power output.ᅠ What is needed is a pre-amplifier to go with it. This preamplifier is the answer.ᅠ It has a gain greater than 40 dB which is more than enough for most applications.ᅠ You may vary the gain by just changing one resistor.ᅠ It will also take its input from an electret microphone by adding one resistor.ᅠ We have provided this resistor and an electret microphone in this kit.

    Power is supplied from any 6V to 12V DC source.ᅠ
    At 12V the current drain is 3mA. ᅠ
    This drops to 2mA at 9V.
