Hi. I am thinking of building this circuit for use as a simple dual polarity power supply, fixed at +/-12v.
**broken link removed**
I was wondering how I would add an LED on indicator, and where. Would it just be the LED and its series resistor between the +15v and gnd rails? Or between +15v and -15v, or somewhere before the regulators? This probably sounds silly, but I know that they can upset the power supply if inproperly installed, but its something i'll really need on this.
