Pedal Power – DIY

Pedal Power Supply

PSU_size

Build this to get a reliable, efficient and quiet power supply for your pedal board.

THIS PROJECT DEALS WITH MAINS POWER AND CAN HARM YOUR LIFE! SO PLEASE TAKE EXTREME CARE WHEN BUILDING THIS !

  • 2 x 9V/12V – 2*600mA power
  • very quiet
  • efficient
  • reliable
  • small in size

The build instructions also contain 1-layer artwork allowing you to etch boards yourself !

    Hi, nice project!
    Stupid question: where did you get that enclosure? It looks great!

    Its called a EURO-Box. Because it is made to hold PCBs in the half/Euro-size PCB format.

    Hi,
    the transformer in the image you’ve posted has 9v as secondary output.
    Does it really mean 9VAC or it already tell you that you will get 9VDC after the diodes? Because according to the formula AC = DC / 0.636 if it is 9VAC you will be getting just 5.7VDC after rectifier and it’s impossible.
    I know it’s a silly question but I’m pretty new to transformers 🙂

    Your formula is wrong 🙂

    XD I did not expect this answer, I saw it here

    So if your transformer has 9VAC as secondary output how much do you get after the rectifier?

    It’s appx 12V.
    9V AC is what these transformers put out at maximum load. Rectification AND buffering via a well dimensionated capacitor! is – that figure can be off a little – 1.26 times the AC number.

    Really thanks for answering!
