PowerSupply_DualRail-Series Extra Notes

This circuit is mainly intended for audio amplifiers requiring dual power
rails but can be used for many other applications.

You should read carefully and understand how this circuit works before you
use it (especially high current versions).

Theory:

The Negative Rail (still being of a positive voltage) boosts the Positive
Rail (like batteries in series).

The Negative Rail negative line takes the negative "series" electron flow
between the 2 voltage regulators.

The 0v/ground line is really only the Positive Rail negative return
providing a half/divided voltage from the series setup. (In theory both
regulator rails could still be used as an independent half series voltage
source.)

The 0v/ground line must be adjusted to having both Positive and Negative
Rails set to the same output voltage (use a good meter).

Future Safety?

Add rail protection current rated diodes (1 out, 1 ground, 1 negative
rail)?

Add more rail protection diodes in parallel (1 @ V+ to ground, 1 @ ground
to V-)?
