    0 30V power supply

    If Q2 with original component(2N2219) is fail. Is it possible, to lower voltage at pin 6(10,5V) because at this moment my power supply deliver max voltage, 35V. I try to change my original circuit with the BD139 and have you got a detail for "two output transistors in parallel (each with a 0.33...
