Steg is(was) from Italy (my country) and it's failed
No italian's companies deliver schematic. They're very jealous.
Steg circuits are very uncommon. For example, the regulation in not the tipical "feedback" mode, but a feed-forward that caused a lot of problem as Eva said @post30: http://www.diyaudio.com/forums/power-supplies/65130-smps-control-loop-estability-3.html
Even the protect circuit, sometimes fails for nothing The protection circuit is in a small SIL card
