Toroidal Transformers (1 Viewer)

What are the advantages of a toroidal transformer over some of the cheaper types? I have come across them several times and they are usually found in more expensive power amps.

Mostly A toridial is more efficient than the common box type transformer. Which means they can be made smaller for a given output. They have a lower magnetic field, so interference to surrunding circuits is minimized, and they also operate quieter. Over the past 5 years ive noticed they have trickled down into more modestly priced equipment.

Torridial transformers radiate magnetic field through mostly through its poles. The strange thing is that one frequently see them placed in such a way that the magnetic field aims directly at the audio circuitry.
