Push Pull Output Transformer
Introduce
- 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 winding, 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 inter-layer 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.
