    This regulated power supply can be adjusted between a few volts and 15V with P1 and with P2 adjust the upper limit ( 15.0V ). R6 value is 0.7V / Imax where Imax is the maximum current. At Imax = 5A, R6 is 0.14Ω

    T1 and T2 must have heatsinks because power losses are great at a low output voltage and a Imax equal current but you can connect the lamp L to reduce this losses.
    I’ve build this adjustable power supply and works great! I hope you’ll enjoy it too and have fun build this great stabilized power supply.

    1. Hi, i think, after my experience, that this circuit can not work. It’s better to write> this circuit work from about 2 volts to max.
      If you want regulate out voltage from zerou, you have to use lm258, lm358 or lm10… This are Operating amplifiers whose can work with small voltage on their inputs. 741 need small negative voltage, becase have on inputs PNP tranzistors.
      Sorry for my english.
