    Some good suggestions, but I still prefer the LM380 over the LM-386. It's MUCH easier to tame, (at least in my experience) and can run off 12/13.8 Volts directly, with 2 Watts out, enough for code practice in even a crowded room, with a decent sized speaker...

    Boy I agree. The LM386 is a harsh sounding beast.

    It can be if it is overdriven and if you want hi-fi sound, but for voice frequencies and lower power, I think it is fine.
