Step 4: Amplifier Socket

It's nice that we have this fancy, filtered signal now, but that's not going to do us a whole lot of good if we can't hear it. The signal we have is weak!

The LM386 is a nice, simple amplifier that will not only make your signal bigger, but also give it more POWER, so that by the time the signal makes it to the speaker or the headphones, you can actually hear it!

Tools Needed

  • Soldering iron
  • Electrical tape

Parts Needed

  • 1 x 4-pin DIP socket


  1. Find the footprint for U6.

  2. Tape it into place as with previous sockets and solder into place.
