r21 is in correct place. Short history of my problem : When i start power supply first time everything was ok. current limiter worked etc... but when i short circuit output then q4 burned, i replace q4 with new 2n3055 and q2 with bd243. Now when i short output curent limiter work v out = 0v but led dont light. In normal operation current limit is work "too good" :) when i turn P2 only little led light and v =0v

Thanks for reply voltage in pin 4 is ok -5.5V problem is that when i turn P2 only little curent limiter is start and v out =0

Hi, can anybody help me ? I have problem with current limiter, when I short output current limiter is works but led dont lights, when I normaly work on this power supply and i want set current limit with P2 led imediatly light and Output voltage is 0V. sorry for my english..
