    KNOWLEDGE BASE --- How to Choose Toroidal Transformer for Audio Amplifiers?

    1. Choose such a toroidal transformer made of a cold-rolled silicon steel sheet iron core. The quality of toroidal transformer depends on the manufacturing process of the iron core. If the process is good enough, the probability of magnetic flux leakage of the transformer is less and the audio equipment will not squeak.

    2. Choose the toroidal transformer with full copper windings that are evenly wound. Compared with gold and silver wires, copper wires are relatively cost-effective and are more suitable for audio equipment.

    3. Select a toroidal transformer with glue-filled holes, copper foils and shielding layers. The glue-filled holes in the middle holes can be installed stably and reduce vibration and noise. Coating copper foils and shieldings can effectively reduce electromagnetic interference and signal interference.

    4. Finally, choose a toroidal transformer manufacturer that can provide complete packaging, clear and tidy labels, product accessories, manuals as well as warranty cards.

    Peaco Support toroidal transformer is made of 16000 gauss silicon steel sheet iron core, which is wound with full copper wires, featuring sufficient power, heavy weight, low temperature rise and CE, CQC certifications.
