Please help me build a power supply that has variable 30 0 -30 volts output and fixed 6 -6 9 -9 volts. Pleaaaase. With short circuit protection and auto polarity detector. I need it in our school project.

What transformer would i use? The output must have a supply current of 2A.

 You can add me @ faceboook. Mark Austin Alfonso Cabrera
