How long will an average 9 volt alkaline battery run an LM386-based amp? I've been using a 9v wall wart but I'm about to convert the amp to battery power for more portability. Adding a 9 volt battery clip is the easiest mod, but if the battery life is going to be really bad I think I can find a way to cram a 6 AA battery holder into the box.
It depends how loud you play. I use a 9V battery and the battery life is rather long. Try it, you can chance the battery setup later if needed.
