Hi Corsa, Here is the pcb in EAGLE for the board at the top of the thread. It is a double sided board because I had it produced at a professional shop. It is somewhat of a challenge to build double sided boards at home.
Note that D2 and D3 need to be filled with a 1N4148 and D7 is not used for the latest version.
Good luck
Hello redwire, thanks a lot for this!! I'm looking for this a long time ago ;D
In really, this is not easy to make on home, i think... hehe
I will try 8)

Hello everyone.
I saw all posts, but my english is poor, so if i will be repetitive, i'm so sorry in advance.
I would like to make this PS and i have the pcb for old version maked yet and all components, and found now this discussion about "problems" of original version. I understood, one of the problems are some components like 2N2219 over-heats, but i just need 24v and 2,5A max, so i have one transformer of 24V - 3A. This is critical for this values? I can change too:
R1 = 2,2 KOhm 2W
R2 = 82 Ohm 2W
R7 = 0,47 Ohm 10W
For dissipate more heat and dont burn.
So only with this changes i can make the old version without burn problems?
Note: I don't need the 30V 3A max, just 24V 2,5A is enough for me.
Thanks in advance and sorry for my bad english.
My best regards,
Andr
