Them are my fingers on that photo:D
I uploaded that ages ago and i still have got the full article and my own PCB layout for that:D
Did you know they have discontinued that power supply now they do no sell it any ore :mad:
After all i find it the best power supply i have used. The best part about it is that it does not cost a lot at all
I have got to add that i know longer use the panel meter now i have designed my own using pic hoping to add digtial control soon.
the best part about building your own PSU ifit breaksdown you can repair it,
good look

Hi All,
Does anybody know why one of the two LM723 is called `VK7200` in the part list? Can it be to protect the kit or is it just a typo? :cool:

Ok thanks, that’s what I suspected.
Sorry no PCB, you could use Eagle to make a circuit board. You only need the main board; the meters are too expensive to build. I would use ready made modules which are much cheaper and easy to find.

Many thanks for the pdf WizPic.
I have a question: What is the value of the current resistors; (in the Velleman's 7200 kit manual marked as R37-R40 with four pieces of nichrome wire).
In your pdf is marked as current resistors and in the silkscreen is reference like 7/10W (4X). What does means? 7 Ohms / 10W is very high value for this.
Can you help me please?

I used for mine 2 10wat 0R1 which made it 0R5 because they are doubled up, i went fro terminial bloack on my design because I did have an original design and found over the years and long use the resistor wire became bad and made it have bad coonections onto PCB.
