Power Supply for Guitar Pedalboard

Complementing my previous project, this time more than an Instructable I just wanted to add a simple design to the pedalboard that I may someday put together.

All of my pedals depend on 9V either battery or external power supply to work. There are some products from Voodoo Labs, MXR, T Rex engineering, and others that provide several isolated 9V outputs. It shouldn’t be complicated to create something similar for much less money

I already have 5 Radioshack 12.6v 300ma PCB Mount Miniature Transformer 273-1385b (pictured). The output current is 300 mA, more than enough to power effect pedals.

The design is the direct application of the LM7809 voltage regulator and I am using SMD diode bridges MB10S.

The design is very simple and I replicated one supply times 5. The schematic and board design are attached. Also included is a PDF file with the traces for the board a 1:1 scale and mirrored ready for PCB transfer.

The application can be downloaded from http://diy-fever.com/software/diylc/
