I always wondered how they wound toroids. Here is a link to a video of that process.

Here is another type of transformer that is becoming popular in audio because of its characteristics.

Like the ones in my DS Audio E1 equalizer and Esoteric DAC. Although I guess there are strong arguments for any type transformer whether it be Toroid, R-core, laminated core, isolation laminated core, and whatever.

Each type has its posotive and negative characteristics. The R core seems to have the lowest radiated energy and less input current rush than toroids. The toroids seem to be the most efficient.

Here is how an R core transformer is wound. It is interesting to note that since the core cross section is round compared to rectangular as with a toroid, the bobbins rotate on the core during winding. There are also O cores.
