AUDIO GRADE POWER TOROIDAL TRANSFORMERS Type TSTA for tube amplifiers TSA Type for tube amplifiers Single-phase TSA type audio grade, toroidal transformers, manufactured and tested in compliance with EN 61558. Toroidal transformers in audio grade realization can satisfy the most demanding electro- acoustic applications. They are marked by the highest quality, noise-free operation and excellent electrical parameters. They are custom made in order to satisfy the individual needs of the recipient. The excellent performance of our products has been achieved by use of the highest quality laboratory selected components. Modifications include but are not limited to: core and coil saturation, electrical and magnetic shields, enclosures filled with epoxy resin, and vibration-proof mounting.
