Hi,
I've used mains HT transformers as modulation transformers in AM amateur transmitters. The results are usually quite acceptable for the comparitively narrow frequency response required. However, I've never tried using a toroidal type, probably because you don't tend to find HT torroids. I supose the closest thing would be a torroidal mains isolation transformer.

Good luck!
