I actually had to re-wind the transformer all by hand, to say that it was tedious is an understatement, the very first time I re-wound it I ended up having to completely strip it down to the bare bobbin and start again because when I put the laminations back in I accidentally cut one of the primary windings with one of the laminations, eventually I succeeded and had a working power transformer.
Because a Toroidal transformer has a core shaped like a ring, the magnetic field is shaped differently compared to a conventional transformer, the magnetic field is more contained, the benefits of that is lower induced hum-noise.
