I have been looking for a self contained, small, AC powered amp for a while, and have not come up with anything. I also wanted to try the AD8397, but it seems to be tricky enough that it needs a PCB, so breadboarding is not an option.
Anyhow, here is what I have come up with, and I am looking for another set of eyes to look for errors or to see if there is anything that might be done better.
The spacing for C1 is odd as it is meant for both Blackgate N series 4.7uF caps as well as some long film caps I have. I also added 2 sets of output taps, one before the coupling caps for headphones, and one after to use it as a preamp -- they are both in strange spots, however. I also figure that if worse comes to worse, I can skip the output cap and put in a small inductor to kill HF noise.
