[QUOTE="Family_Dog, post: 858903, member: 82"] The Primary is wired correctly for 230V AC, take brown to Live and blue to Neutral. The secondary windings are also in series for 90v output - correct if that is what yo want - and take the yellow & black windings to the ~ mark on the bridge rectifier, which should be screwed down on a metal surface. I would also insert a fuse in the Mains supply (brown wire) as well as one in the secondary wire (yellow or black), with a suitable rating. For the secondary, depending on current draw, 7.5A slow-blow might do, depending on the load or surge current if you are fitting caps after the rectifier. -F_D [/QUOTE]
