Hi,
I have just built a solid state amplifier from runoffgroove.com called Ruby and it works and sounds great! I am most definitely a newbie though and while I can follow directions and solder ok I really have no idea how to do any kind of circuit design.
The design calls for a 9V battery. I would like to build something that would allow both a battery and a 9VDC power supply and have the battery automatically disconnected if the 9VDC supply is plugged in. So it would run off the battery normally until the 9VDC power supply is plugged in which would switch the battery off and run off the power supply instead.
Does anyone have a simple circuit diagram that can accomplish this or could point me to a site that might? I have tried Googling this already which is what led me here and so far have not found what I am looking for.
