Thx man. Sorry to bother you
-
Would you mind posting a link to the modified circuit?
-
Solved it. I accidentaly put the wrong transistor in the wrong place.
Just one more thing. I tested one circuit (I built two) by shorting the output to see the max current rating and it put out almost 5 amps. Those 5 amps burned through the rectifier diodes but everything else was fine. Did you get 5 amps as max current on the output? -
after about two more hours of tinkering with the psu i finally got some kind of reaction on the output of the psu but now i can only get either 0V or 31V nothing in between
any suggestions? -
hey guys i need some help
i've built this psu project from the first schematic (the original) with the tl081 and everything and it didn't burn up immediately after being switched on as suggested by some
i tried testing the circuit and the current limitation/regulation works fine but voltage regulation does not and im wondering if anyone has had the same problem or if someone has a suggestion as to how to fix this problem
this is a great project and i need this psu for some other projects and i've spent quite a lot of money on parts (electronics parts are still a bit expensive where i live) and i would hate it this build was a waste of time and money
please help and thank you in advance

Yes, sadly :)
I found out the hard way that the PSU generates around 26 - 27V at 3.5 amps
In the near future I'll make the upgraded version and i will, hopefully, design a pcb (if one is not available) and post it here.
