Microphone Preamp Power Supply

diposkan pada tanggal 26 Sep 2009 03.53 oleh IBRAHIM BIN KADRI

Here is a simple PSU to power a microphone pre amp. It will supply +15v,   -15v & 48v. If a 7818/7918 pair of regulators is used, then the PSU will supply (surprise) +18v, -18v & 48v. The un-marked diode near C14 is a 1N4003 or better.
