Hello again. I managed to finish the PSU. It worked perfectly from the first time. (except the GND trace under-dimensioned, but I fixed it ;D) Some pictures:

Ok. Thanks for the clarification. I'll gather the components for PSU. :)

Yes, I want to have 6 A at the output but I also want to reduce the heat dissipated by transistors.

Even if we use 2 x BD139 in Darlington connection? Or you can i replace BD139 with BD681 ?

How about if we replace the bd139 with tip112, and so we could drive 4 x 2N3055?
