FAQ:

Q: Which is toroidal transformer for an audio amplifier?

A: All copper toroidal transformer for audio power amplifier, it is 120VA , single phase, small size and weight, is designed for converting AC supply voltages to one or more AC voltages, for example 110V to 12V or 230V to 2 x 24V (24-0-24).

Q: What does a toroid power transformer look like?

A: The toroid looks like a doughnut, with windings equally spaced around the diameter of the transformer (Photo 6). Toroids are also available potted inside metal or plastic cans, or molded inside plastic resin and equipped with pins to mount directly onto a PC board.

Q: What kind of transformers are used in amplifiers?

A: There are two types of transformer normally used in the hi-fi world, EI transformers and toroidal transformers. What is a toroidal transformer? Our first ever product, the P40 integrated amplifier went down in the history books as the first amplifier to use a toroidal transformer.

Q: Why are toroidal transformers more efficient than ei Transformers?

A: The fact that there are no discontinuities in the core makes the toroid very efficient and reduces stray flux to around 10% of that of a comparable EI transformer. Toroidal transformers still leak magnetic fields, mostly because the windings are not symmetrical — the wires are spaced farther apart on the outer diameter of the core than the inner.
