heavyd Witha 470 ohms resistor at position R1 and R4 and a variable resistor R2 and R3 of 10kohms you can get a regulation of 1.2V to 27V. Resistor of 120 ohms position RA1 I do not use it (the value is too small to regulate the current through the LED), depends on which output voltage will adjust (for 2x15V the resistance should be 1.5 kohms, for 2x24V - 2.7 kohms)
