Have tried in the past with simpler circuits using some freeware programmes but found it so difficult, they always turned out a mess. Gave up in frustration in the end. This circuit is much more involved than the ones I have tried to do. I think I remember reading in the forums the above gerbers were done and posted for download a long time ago but my searches for them now have failed.Good Luck finding them.
Why can't you make ur own ?
Thanks a lot Max. I have already used this layout and have modified it to match the above circuit but when I sent it (in jpg, pdf and doc format) to the company that makes professional boards they asked me for the Gerber files.Here is a sample board layout from a DIY board.

Thanks Max, am downloading Kicad now and will try again.Try using just the PCB layout feature on a free board SW, I use Kicad and although I have never done it by bypassing the schematic, you may be able to lay it out manually and then produce the Gerber files.
Probabally a bit of a learning curve to that though.

Yes. There have been hundreds of discussions on this one in great detail in at least two other threads on All About Circuits. Over the years most of them have been lost, scattered or fragmented. There are a number of serious issues with these kits all of which have been fixed mainly by Audioguru and other members. The latest successfully working om (0-30v and increased to 5A) is rev 7 above. See attached summery. I have been following the threads since about August last year and have decided to build this one. (There are variations on other sites)It should be more like 0-25V, 0-2Amp Supply
You may be interested in this 723 circuit I found some time ago.Son of a Gun..!!
I was right.
And that's why I an building my own. My one has more components though. Uses LM723 for VI Regulation.
Looks good. Would love to see the circuit. (Please post). If you need help with the manufacutre of the board I live around the corner from a company that makes professional boards but only from gerber files. I could pop around to them for you, there turnaround time is two to three days.That is child's play compared to what I am making.
Mine has two LM723. one for voltage and one for current regulation.
Plus a LCD VA meter, over temperature (heatsink) shut down, fault alarms and output on off features.
Here is PCB layout just for reference. I am planning to make the PCB from a China fabricator.
