Stereo Headphone Amplifier
This is an improved version of headphone amplifier I’ve built many years ago. I wanted so much to share it with you because this simple circuit has done a great service to me through all these years. It is very simple and reliable, hard to break, offers a lot of power, excellent sound quality, it is built with just a few simple parts and more importantly it has a very little power consumption. With just two AA batteries it can work for a very loong loooong time ;). Link
