I am building a power supply. The question I have is what is the difference of using a pass transistor's base, hooking it up at the input of say a 15 volt regulator vs the base of the pass transistor hooked to the output of the regulator. I have seen both ways, have tried both ways but I don't know which way is preferred, or better. My test show you get more output when the output of the regulator is connected to the base of the pass transistor. when I mean more output, I mean more current at the output.
