REGULATED POWER SUPPLY RTS PCB

The ready-to-solder PCB for a simple regulated power supply, for clean, quiet power to one or several of your pedals.

About this PCB

Regulated power is clean power, and this small board is the heart of a supply that can run multiple pedals at once. The transformer mounts off the board. The board has room for a standard heat sink on the regulator and accepts either a diode bridge package or four separate diodes for rectification. A second layout covers a rectified (DC) power input, and the Power Box project shows how to use several of these boards to provide multiple outputs from one box.

Safety note: this project involves 120V AC household current, and mistakes can cause death or serious injury. Only build it if you know the relevant electrical safety rules. If you use a 3-prong plug, the ground wire must be securely bolted to the metal enclosure, as in an amplifier; if you cannot do that, use a 2-prong plug.
