     The main balanced power supply is constructed with the usual suspects, 7815 (pos 15 volt regulator) and 7915 (neg 15 volt regulator). These are fed from rectified AC via a PCB mount 6VA power transformer. I have use four diodes in a bridge rectifier configuration rather than a dedicated bridge rectifier as people have had trouble finding P04 and W04 rectifiers and it allows you to get esoteric with low noise switching diodes. I used the simple and easy to get IN4004 but some at Tech Talk have suggested more exotic devices.
