High Performance AUDIO 290VA Mains Toroidal Transformer VTX1460001290 – An efficient and compact electrical audio component, the VTX-146-0001 Series is specifically used in audio equipment to convert high-voltage AC mains power into the required voltages suitable for use by audio circuits. Its toroidal (donut-shaped) core design minimises electromagnetic interference (EMI) and hum, resulting in cleaner power delivery and improved sound quality. It is favoured in high-fidelity audio systems for its low noise, high efficiency, and compact size. These toroidals are made with 2 layers of GOSS band sheilding for added noise elimination.
