Features:
LINLAITUBE 300B-Z electronic tube replaces the 300B moldy screen white porcelain gold-plated pin pin. This product uses a large electronic glass shell, and the inner surface is precisely coated with monocrystalline carbon to quickly absorb the temperature inside the tube and dissipate it out of the tube in time. At the same time, the interference of external clutter signals on the sound quality is shielded; in order to obtain a high-density cathode emission current, the tungsten material imported from Japan Toshiba is used. 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 gold grid wire, which completely prevents the grid’s thermal radiation, which not only improves product life but also reduces tube noise; the tube bottom adopts aesthetic creativity, and the tube needle is electroplated with pure gold to improve electrical conductivity , Reduce signal loss, improve power output channel.
