Hi All,
I've been searching through the forum as well as other sites and there are just too many projects out there to look at. I'm hoping someone will be able to suggest a power supply for me that they have experience building/using.
I need/want a power supply for my pedals, to simultaneously power both positive and negative ground pedals at 9V and also be able to switch from using either 120V and 240V as I travel between US and Australia. I believe that I can get transformers that do this, but can anyone suggest a good DIY project that ticks these boxes?
Cheers,
I have not seen a project that covers everything that you want.
However, you can learn pretty much everything you need so you can do what you want between R.G.'s Power Supply Basics for Effects (http://www.geofex.com/Article_Folders/Power-supplies/powersup.htm) and The Spyder - an Eight-Output Pedalboard Power Supply (http://www.geofex.com/article_folders/spyder/spyder.htm) articles.
Smallbear and Weber sell a transformer for pedal power supplies that can use either line voltage, so you can probably work out switching between the two.
