Push-Pull Output Transformer

Product Description
1. The Z11 silicon steel sheet, imported from Japan, is 0.35mm thick, high-induction and grain-oriented, is adopted to efficiently reduce the iron loss and to ensure the quality of sound range from high to low.
2. Special winding technique can eliminate the inductance loss of primary windings, reduce total harmonic distortion and the phase shift between High & low frequency. Particularly recommended for the output of vacuum tube amplifiers.
3. All coils are manufactured by Taiwan leading magnet wire companies. The thicker diameter magnet wires are high conductance, low copper loss and used to control temperature efficiently.
4. Proper insulation configuration helps to decline interlayer capacitance and balance the acoustics around a wide range.
5. Precise impedance statement, lower heating value, no "hum" sounds.
6. 100% MIT (Made in Taiwan); Customization are available.
7. Jian Ming has a wealth of experience having developed dozens of vacuum tube amplifiers for Hi-End & HiFi audio companies in Taiwan. We are happy to brainstorm potential ideas or concepts for new products.
