Is normal to have 45V at the + and - of the bridge diode? ??? LE: I use 28V ac transformer. If P2 shortcuts Pin3 of U3 with R18=U3 gets very hot; if P2 shortcuts Pin3 of U3 with R17=U2 gets very hot, led also turns on; I don't know too much electronics and I need someone to help me troubleshoot this power source. I've spent too many hours just to throw it away. :-\

Hi again. I've just finished the PSu work and I got some problems. U3 gets instantly very very hot after i plug it in. Also The current control potentiometer acts like voltage regulator and it regulates between 15 and 38 V. I really need some help. Ty.

Thank you for your quick reply. I will keep in touch.

Hi everyone, I've made an online order for TLE2141 and i forgot to ask what package is build in. So i'm stuck with these. Will my psu work?
