My version of a Cmoy amp. I call it the Mini Amp. In this first part I am starting with soldering the SMD components and in the second part I will finish the board by soldering on the trough-hole components. I use solder paste and a hot-air gun because I don't own a reflow oven. This is not the preferred way to do it, but it works as long as you are careful not to burn stuff!
