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 -
audioguru, thanks for your help here are the measuraments
I am using a 12+12/2A transformer connecting both 12+ in 1 and 2
I am using R7 with 470 ohm instead of 0,47 ohm I will change for the right one...
1) Positive of C1. 42.4v
2) Pin 4 of U2 and U3. 1.41v 5,08v
3) Pin 6 of U1 0v
4) Pin 6 of U2 with the voltage pot up then down. 0,0 2,9v -
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!

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!
