Thanks thanks for all the answers So you mean I should change the 2n2219 to a bd139 with heatsink? That's good because I still have a bd139 :D It's very good that the opamps are not broke down but if they will break down I will change it to the better opamps you mentioned. I will tell you when I repaired the PSU and it work. Thanks anotherone ;D

Hey Thanks for the reply Here are the voltages: Output: U1 = 11,24V that voltage is constant no matter of the setting of the potentiometers U2 ~ 31,5V that is at highest setting of the voltage potentiometer and if I turn down the voltage below 0,8V (meanwhile 0,8V is the maximum voltage, at first it was 2V and it sinks permanent) U3 ~ 32,9V if I activate the current control it sinks heavily but i think that is normal, right? Emitter: 0,32V and it sinks permanent also if I don't do anything When I built the PSU I measured the supply voltage on the opamps but the voltage wasn't higher then the maximum voltage of them so I thought that the post on the homepage about the supply voltage of the opamps wasn't right. This is the post i mentioned ".If you connect them as it is shown in this circuit diagram that voltage will be about 45VDC, so they will burn down immediately." Clemens

Hello!! I'm from Austria, so please excuse if I don't speak english well ;) One month ago I built the version of the PSU which is on the homepage and it worked very well. But few days ago it broke down and I don't know how it works and so I'm not able to repair it without your help. The problem is that the voltage doesn't rise higher 2V.... :-\ I hope you can help me to repair it and please speak nice english, else I wouldn't understand it ;) Thanks Clemens
