I've got some schematics published in this month's Make magazine. What a hoot! Build an amp using a cereal box as the case. So here's one of my first questions I hope somebody can discuss.
Does the type and capacity of a battery affect an amplifier's ability to output volume? Some of the teeny little practice amps run on a 9v battery but can't be heard well outside. Given the other concerns being met is it possible to get more volume using a different power source such as a battery from a laptop computer typically 10.8v or some other battery type with greater voltage?
