copper layer shorts
I assembled my entire amp3 kit before looking over the PCB. There were some pretty bad copper splotches from the PCB process that shorted the input VCC/gnd, had to desolder a lot before I could wedge in a razor to fix the problem. (can post pictures if people are interested in seeing it.)
so check the PCB -first- for coppper splotches BEFORE you solder on parts.
also, perhaps a higher quality PCB manufacturer would be a good idea? or paying the extra $ for PCB test? I know i will be from now on for my kits...that was really annoying!
otherwise, works great! looking forward to getting more of these
