Introduction
This is the Project Builder's Guide for issue 1 of the power supply unit, PSU2, circuit board
from Oakley Sound. This document hopefully contains everything you need to know to build
and install the Oakley power supply unit.
The PSU2 allows for various options in the installation. You can use the unit either in full
wave rectification mode for connection to tapped linelumps or twin transformer secondaries,
or in half wave rectification for single phase AC output wallwarts and linelumps. If all this
sounds very confusing at the moment, do not worry, in this manual I will try to make it clearer
so that you make the right decision about what power source you will need.
It is designed to be mounted onto a metal panel which is used as a heatsink for the two power
devices used on the board. Mounting your power supply to a metal panel on the outside of
your case helps keep your modular cool.
