Whats the standpoint about snubbers BEFORE the caps ?
A snubber always helps at high-freq to eliminate the local,
resonances created by the parasite inductances, and capacitances.
Before the caps:
Inductance come from the trafos secondary wires,
and capacitances from the rectifier diodes.
After the caps:
Inductances are comming from the caps internal "wires",
and capacitances are obvious.

I know, this was on focus earlier, but i dont remember to the
results, and these topics have a lot of pages...
So, shouldnt we apply snubbers before the caps, at the diodes,
like at the second link, based on the same cause whats in the first link ?
Where is it more important and effective ?
