This general purpose power supply can e used for supply output voltages from 1 to 35V. The line transformer should be selected to give about 1.4 times the desired output voltage from the positive side of filter capacitor C1 to ground. Potentiometer R2 sets the output voltage to the desired value by adjusting the reference [...]

The Circuit power supply regulator 0-50V 2A by IC LM723 + Transistor 2N3055 & BD140 & A671 is nice Pwer supply, For all electronic user. You can Current control by VR 5K, LED5 For display OVERLOAD. To use transformer 3A, Transistor to Hold Heatsink. To adjust the output voltage< VR1 – 5K (VOLT CONTROL) OUTPUT [...]
