Mains Op-amp PSU

Introduction

This project came about because I wanted something better than the old 7815/7915 regulator combinaton. I was surprised to see that nobody seemed to have a PCB produced for the LM317/337 regulators, let alone a good implementation. So after much studying of the datasheets and several layouts I came up with this design. I am quite pleased with it :-) There are a number of good features such as the star connections used for the regulator feedback network and also the 0V/gnd.
