Further Information

Brand New LINLAI WE300B Vacuum Tube Audio Valve Replace 300B for Electronic Tube Amplifier - Genuine Factory Precision Matched Pair

Features of WE300B:

The screen made of glass molybdenum alloy and carbonized has very high purity, strong electronic emission capacity and service life, and the tube core is suspended from the glass shell, effectively avoiding vibration noise. The four rods strengthen the support of the tube core, as stable as Mount Tai. The voice is exquisite, the details are more abundant, more transparent, delicate, mellow, the air sense, the sense of hierarchy, the analytic power is stronger, and the gall flavor has more advantages. This product is designed and produced by Changsha Qiangsheng Electronic Tube Factory, a high-end designer and craftsman. This is the most successful product for copying WE300B electronic tubes in China at present, completely 1:1 copying WE300B. The appearance is long and elegant. The cathode activity is superior to that of the ordinary 300B tube. The platinum grid removes the return grid current, and the sound quality is pure and sweet. The superconducting anode material is covered with a radiation and heat dissipation coating, which greatly improves the board consumption. The whole tube works easily and freely.

WE300B Voice:

It is soft and delicate, with high sound density, richer details, stronger analytical power, pure, sweet and mellow, and outstanding sense of hierarchy.

WE300B directly heated cathode medium power triode, used for Class A1 amplification.
