I wanted to build a few audio amplifiers to have on hand for future QRP projects. I went nuts and built a bunch. The design uses discrete BJTs, and is noticeably quieter than LM386 designs. Specs: V+ 6 to 15 volts, quiescent current <10 mA at 12v. 50 mV @ 1K input gives 1.2V @ 8 ohm out (12V supply) Very low distortion to about 200mW. Board 1x1.25 inches 10 available. Can install in/out/V+ leads if desired. Each unit has been tested and biased for 12 volt supply; you may specify a different V+. Will refund 100% if not up to specs; you pay shipping if you just don't like it. The board mounted pot in the picture is not a volume control. $9 each shipped, $15 for two (stereo).
