Audioguru, My new measurements: C1 + 33V Pin 4 U3 -5,7v Pin 4 U2 -5,7v Pin 6 U6 8,1v Pin 6 U2 5,1v - 8,0 voltage pot down then up. LED always on Output voltage 25,4v - 32,4v The only thing that I changed on the project is the R7 with 470 ohm instead of 0,47 ohm, I will try to find the right one Thanks in advance!

Thanks for your help audioguru, I will measure things again as soon as possible, my home multimeter is to very good, i will use the one on my college lab Do you have by any chance this project on a pspice file so I can simulate and have more voltage readings to check? if you have can you send it to me to best regards

Hi all, On my first attempt on building this Power Supply, I am having some problems can some one help me troubleshoot ? I am a newbee in eletronics but I have to have this PSU working by 11/22/06. When I turn it on the LED is on, the 2 potenciometers are apparently dead and I got a 33V on the output ???... Thanks in advance!
