I got an answer from the spanish representative of Bryston, they said the warranty is only valid if I send it to Bryston in Canada so I opened up the B100, the external fuse is ok but my internal "surge protector" fuse is blown. Its the T125MAL250V fuse.
I have ordered some new fuses.
I also plan on using my system with a DC filter from now on, who knows, might help.
