PAGE 2 of 4 - General WARNING
Part of this circuit is connected to the mains electricity which can be lethal proceed with caution !
A few advices about working with mains:
Always ground conductive parts of your working area, your project boxes or whatever is conductive and can get in contact with mains electricity.
Always check that you have disconnected mains voltage physically NOT with a switch or any other mechanical/electronic way before you go in with your hands. its not uncommon for switches to fail also some switches only disconnect one line and in countries like mine you can turn around the plug in your wall so if you turn around the plug you can get live wire still present even with the switch being off
If you need to take measurement of high voltages make sure your equipment is rated for such measurement and is undamaged

This power supply can be used to power amplifiers or lab, because the LM723 is a very good voltage regulator, with good specifications, like noise figure. It has sense voltage, feedback, overall protection. It is a way good comparing to LM317 series. It can be used for a final year project at university, if it has a documentation. I've seen at my university, final year projects like power supply with digital view of voltage.

I uploaded PDF with my second populated unit pictures ( On presentation page click download file) it should be easy to build in one go but if you have questions ask them in comments ill spare some time to answer.

3 months ago my house caught fire from neighbours burning house resulting in my house burning down to along with the computer with files for this build, my prototype burned down also but i redone schematic and even built a new unit i can post schematic PCB files and silk screen files AS IS. for now i cant write any text for it, at the moment im working 2 jobs to rebuild my home. anyway ill post files in PDF and they will be on first page

Any news? I'm a newbie electronics student at an electronics vocational trainingschool, I can get most parts cheaply or for free at the lab. I have zero incomes, so I must get smart and do my equipment in the DIY way.

@george schematic have some mistakes also the pcb, once i get time to fix the files will write complete text im sorry i couldn't do this in one go but work i do demands a lot of my time stay tuned the prototype works really well will be worth waiting
