As Yoda would say, there is no repair, only transplanting. If the transformer goes out on a Necchi, the only cure is a transplant. Or you can rewire it so there's no slow/ fast speed, and a new light, or a transformer only for the 12volt light. As you said, another step down. Sob! And yes, this is the one with the cool cams.
