Actually your first upload is the newest version.your right they are good to learn with and it is a nice supply,If memory serves me I think the only problem was some noise on it,wasn't very clean voltage?
I'll see if I can find those old post.Never seen that  second one you posted look's like it was re-worked but I  can't translate the Doc so I don't know what they did regarding the Lt1491 and the lm358's.
Good upload anyway -- keep it up  Grin
