Ned, I still use the original amp i built using the schematic you designed for me. I couldn't figure out how to wire it in a way that wouldn't send too much voltage to the LM386, so i ended up installing two DC inputs with a toggle switch. That works fine, but is inconvenient and unprofessional. I'm going to build a number of these for other people now, so i'm wanting to do a better job of it this time around. I would simply upgrade to the LM386-N4, but i've already purchased a bulk supply of the LM386's.
I like audioguru's idea of using an IC charger chip because it seems like it might be simpler and more cost effective. I'm trying to keep my costs as low as possible, including my time. What do you think?
Thanks a TON, you guys rock.
