New. Improved. Stays crunchy in milk.

Amped!

Posted by Russell on July 03, 2006 at 5:37 a.m.
I just finished debugging and assembling my very first audio amplifier. It's a thumping 2.5 Watts of single-channel sound. I built it around the mighty LM380 2.5W Audio Power Amplifier. I also have a preamplifier stage, which turns out to be rather unnecessary for stepping up the line input from (for example) my iPod.

It's powered by a 9-Volt battery that I've squashed inside. Not quite audiophile material, but I want to build a real audiophile-quality amplifier someday, and I figured I ought to start somewhere.
