How to reduce 12 v to 9 v?
« : April 15, 2012, 08:54:56 AM »

I've made framus cobra preamp, with FETs and Im running it with 12v power supply. I would like to put ROG's condor cab simulator in the same box, but condor requires 9v. Any advice?

The Condor will run fine on 12V.

use a 10v 1 watt zener diode with a 100 ohm resistor..very simple..makes a great voltage regulator....

A 78L09 provide regulated 9V without wasting as much power as a zener.

Go read geofex.com.

In this case, Power Supplies Basics (http://geofex.com/Article_Folders/Power-supplies/powersup.htm), from 2001.
