Title: Linear power supply
Review: Wasn't expecting a linear power supply. I thought those things were a thing of the past like incandescent light bulbs. All the pluses and minuses of a linear power supply, quiet, reliable, heavy (relatively), inefficient, etc. I like that they give you the full schematic with it. (a transformer, some diodes, op amp, NAND gates, and two LEDs) This thing will last forever.
