It would be good to know how to build some of these things , voodoo want 215$can for one of these units , are they really worth the money they ask ????
<=== my avatar is the circuit board layout for my standard power supply.
This is similar to one output of the Voodoo, the Voodoo has a complete regulator circuit and an independent transformer winding for each output.
I believe the Voodoo is priced correctly for what it does... but... I've never had any trouble with the circuit in the thread referenced above powering multiple pedals.
