Sometimes you'll notice in the photos that something looks like it's been done before, some parts will be already soldered or cut. That's because this is kind of a staged instructable, since i had the amp done before starting the ible. I actually teared it apart and put it back toghether to show you fellas how to make yours.
That said, let us begin!
Step 1: Parts Needed
1x Heineken Mini-Keg (the small one, non returnable, 5L in capacity. other brands do it just as well, but don't forget the cool factor)
1x Amp circuitry
1x 120v to 9v transformer
1x Mains cable+plug
2x 3.5mm mono jack
2x 1/4" mono jack
1x Indicator LED, color to your taste
1x Toggle switch
1x 10k Log Pot
20x M5 x 25 Allen Screw
24x M5 Nut
8x M5 Washer
2x M3 Philips Head Screw
4x Rubber Bumper or any other shock absorbing bumper
4x Rubber band (the strongest you can get)
4x Speakers, various sizes, between 2 and 8 ohm, salvaged
Xx Metal mesh, enough to cover the speakers
- I'm using four speakers, in three different sizes. By using templates like i'll show, you can use as differente and as many speakers as you wish/your amp can drive/fit in the keg.
- The 2x M3 philips screw came from a random parts bin, and are used to hold the transformer. If you are using a transformer not identical to mine (needless to say, you are), look for the right screws to hold it down.
