NEW PSU V1.1

I made a few small changes to this V1.0  PSU :

V1.0 with SMD chemical capacitors

Compared to version 1.0, I changed the type of chemical capacitors and switched from SMD models to through-hole models. 

Beyond the fact that chemical SMD capacitors are quite difficult to solder, whether manually or automatically, I have bad experiences with the reliability over time of this type of capacitor.

I also put some distance between the two output terminal blocks to facilitate the insertion of cables on the first terminal block (MAIN_1).

And for fun, a small family photo of the evolution of this type of power supply:
