A few remarks:
- The amplifying caps (orange) that I got from DigiKey were quite a bit larger than I expected them to be. As a result, I had to adjust the layout slightly, and I wasn't able to fit a pot in my enclosure.
- The hardest part of this project was soldering on the prototype board, as the components and terminals were quite small and close together, while the soldering iron I bought was large and clunky.
- The amp definitely makes music louder (amplifier gain is 11), but its difficult to say for certain that it sounds better. In the future, I'll probably play around with higher capacitance capacitors to see what effect they have on the sound.
Overall it was an interesting, rewarding, and inexpensive project (that is, the materials required for the actual amp were cheap, however the tools needed were a bit costly).
