Hello,

Check that D7 is fitted the right way round.
In the other direction the mentioned voltage would be possible.

Hi guys !
First i'm new member here with you , and i hope you guys help me with my power supply kit problem:
Like most people , i have problem with this kit wich is i get -0.45v when the V and A pot are fully anti-clockwise and i get only 5.1V when the V and A are fully clockwise.
I checked almost the whole circuit with the help of schematic that is made by "Netzener" .
I'm using 12-0-12 , 3A transformer...
So guys can you guess where is the probleme? I will attach a pdf file wich can help you understant the whole circuit...
Thank you .
