PAGE 1 of 4 - Getting Started
To get started first we will need items needed for this build so lets start there
NOTE: if you would like more replacements of the parts write in the comments these parts are parts that every electronic store has and at the time when i designed this i designed it around the parts i had in my junk box
|TR21||2x6V 0.2A this is a center taped transformer meaning it has 2x secondary|
|D7||ZF7V5 or any 7.5v zener diode|
|D8||ZF15 or any 15v zener diode|
|D9,D10,D11,D12||1N4004 or any 1A rectifier diode|
|DISP 1,2,3,4 ||13mm Common anode 7 segment displays chose your color|
|LED1||3mm LED chose your color|
|C3,C4,C12,C13,C15,C17,C18,C19||1╬╝F 35V Tantalum capacitors or electrolytic|
|C14,C16 ||1000╬╝F 16V|
|R1, R27||300R 0.5W|
|R19||0.1R 5W In schematic these are shown as 1 resistor but they are actualy 2 in paralel|
|R24||1k small trimmer potentiometer|
|P1, P3||50k linear potentiometer|
|P2, P4||5k linear potentiometer|
|R6, R13, R14||1k|
|IC3, IC4||MC1458 DIP|
When searching capacitors sometimes its good to search like this for example 0.47╬╝F if result doesn't show any results try converting it into nano-farads 470nF then search again

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
