How homemade can the amplifier get?...

So I've been into making little 9v amps built in to cigar boxes (with the lm386) and i've started to wonder about these pricey components that I'm getting at Radio Shack... What if...I could make them myself? http://blog.makezine.com/archive/2009/02/make_presents_the_capacitor.html?CMP=OTC-0D6B48984890 http://blog.makezine.com/archive/2008/12/make_presents_the_resisto.html These videos seem crazy how simple they work. I could wind my own speaker with a magnet easily, make my own capacitors and resistors, and basically (not including the input jack and lm386) have a completely homemade amp. Is it possible, in your opinions? Anyone ever try this? --Charlie

  • Get your parts from somewhere like Mouser. They are a fraction of the price Radio Shack charges.
  • Yeah, those definitely would be hard. I'm gonna try this design:

    The hard part in that design would be the lm386 amp chip, and with that, I think I'll just buy it.
    No vacuum tubes in that one, though! A tiny bit easier haha!

    The triode (transisters) might be a problem. Not sure how you'd do it without a vacuum tube - although the tube is a pretty simple device if you have a way to make a vacuum.
