The Post-Apocalyptic Tin Can Amplifier


In the case of an apocalyptic nuclear fallout, and you emerge from an underground bomb shelter seeing nothing but a wasteland on top of what was once a thriving human civilization - have no fear! Let this video be your guide to scavenging the parts necessary to build yourself a guitar amplifier so that you can waste your numbered days away shredding guitar and rotting from the side-effects of radiation!

This amplifier can be powered by a 9V battery or DC power, and the size of it makes it a wonderful travel amp.

Here's the list of components we'll need:

  • An LM386 amplifier chip
  • A 220uF electrolytic capacitors
  • Two 10uF electrolytic capacitors
  • A 47nF capacitor (usually film)
  • A 1nF capacitor (usually ceramic)
  • A 10ohm resistor
  • A 9 volt battery connector
  • A DC Jack - this can be switched or not switched
  • If the DC jack is not switched then, you'll need a SPDT slider switch
  • A push button
  • Two 1/4" mono panel jacks
  • A 20k ohm log taper potentiometer
  • A small paper protoboard
  • And a tin can that fits all the components.
