Making an audio mixer for my computer. Part 1 - 2073D as Headphone amp

Time for a new audio project. After the failure that was my previous audio mixer for my computer's audio outputs (and other things). I thought I would try again. I will be doing 3 circuits. A Headphone amp, a VU meter circuit, and of course the mixer itself. In this video I tackle the headphone amp, using a 2073D chip I found in some junked electronics.
