I'm working on a project to transfer the 'innards' of one of the Radio Shack voice amps to a small project box, and had a question about changing the battery type.
I've heard some people have substituted a 9V battery in place of the six AAs. I understand the voltage is the same (1.5v times 6 = 9v), but does the battery life change at all? Usually I can get through quite a few hours of trooping on the six AAs. Will it be the same with the 9V?
Mods, since we don't have an Electronics forum, feel free to move this to wherever it's supposed to be.
