Features:
845-TA This product uses a large electronic glass shell, and the inner surface is precisely coated with single crystal carbon to quickly absorb the temperature inside the tube and dissipate it to the outside of the tube in time. At the same time, it shields the interference of external clutter signals on the sound quality; The high-density cathode emission current adopts the thorium tungsten material imported from Toshiba, Japan. Compared with other similar tube types, the emission area of the cathode is increased by more than 10%, ensuring sufficient supply capacity for large signals; the grid adopts sufficient The gold covering completely prevents the thermal radiation of the grid, which not only improves the life of the product but also reduces the noise of the tube; the bottom of the tube adopts aesthetic creativity, and the tube needle is pure gold electroplating to improve the electrical conductivity, reduce signal loss, and improve the power output channel. It is especially emphasized that the product has adopted a high withstand voltage design, and there will be no flashover phenomenon.
