I was going to use a LM-386 in my last project, but the Junk store didn't have one. SO I went to FRYS and found an audio chip it had for a replacement in a car radio. I found the circuit to it on the Internet and wired it up. Much more power than the LM-386 and great audio quality. I put in 2 large speakers for it to drive and ran the input from my PDA audio out to listen to music! So if it makes a great IPOD Boom box, it ought to make a good Ham Transceiver audio system too. Of course, I am going to have a back panel input to select external audio for use when I need to listen to music.
