August 1984 73 Magazine has one called the Cheap Power Ploy. I built one
years ago, it works great. Page 10

Anyone know where I can see a schematic of a common emitter power
supply? I've always read about using the emitter of a pass transistor
as the positive terminal output (Common collector). Taking apart this
trip lite power supply I see that they have the negative terminal
connecting to the collector of the npn pass transistors. This seems
like it would extremely complicate the regulation design. Can anyone
explain the benefits, and where I can learn more about this design
technique?
