LM317T Voltage Regulator with Pass Transistor

this is a homemade lab power supply. 2 - 32 volts 4amps. it is based on the lm723 regulator on a home made printed circuit board. the transformer and caps came from axeman surplus store. the meters came from some really old equipment. the amp meter has a homemade shunt. the case is made from the shell of an old microwave. a shot goes out to my uncle that helped with the case. here is the schematic i based it on. hmin.tripod.com
