Adjustable Lab Power Supply - take two :)

So, the previous article about lab power supply gathered quite a interest which is not a big surprise considering that there are over 200 pages of discussions in two topics about the schematic in this forum: http://www.electronics-lab.com/forum/index.php?board=2.0!

I think that the schematic in www.electronics-lab.com is not the original one but a modification of an older schematic published in a Czech electronic magazine. I found it here: http://paja-trb.cz/konstrukce/zdroj.html  There are scanned pages from the magazine with the original article and eagle files for the project.

Adjustable lab power supply

I already have several lab power supplies, all of them made by myself. The latest (shown here in action) was almost perfect - two channels, 1.2 - 30V/3A - but there wasn't current limiting. That's why I was searching for suitable schematic to build. What I found is this schematic: http://www.electronics-lab.com/projects/power/001/index.html.
It has adjustable output voltage from 0 to 30V and adjustable max output current from few miliamperes to 3 amperes.
As it turns out there are serious flaws in it, but in the forum in that site it was thoroughly discussed and the member audioguru proposed an improved schematic, in which all flaws were addressed. I used his schematic to build my new power supply.
