ANKER MIFA LINLAI WE300B Vacuum Tube upgrade PSVANE KR300B 300B Electronic Tube Series Applies to Audio Amplifier

Features：

WE300B has better vocals, richer details, more transparent, delicate, rounded, airy, layered, stronger resolution, and more attractive. This product is designed and produced by the high-end design and craftsman of Changsha Qiangsheng Electronic Tube Factory. This is currently the most successful product for re-engraving the WE300B tube in China. It is a 1:1 re-enactment version. The appearance is slender and elegant, which is completely comparable to the original western electric tube, which highlights the strength of Qiangsheng's products .

The complete set of tube materials is specially ordered from the supplier of XD electronic tube materials. Excellent cathode activity, beyond the ordinary 300B tube, platinum grid removes the back-gate current, and the sound quality is pure and sweet. The superconducting anode material supports the radiation heat dissipation coating, which greatly increases the board consumption, and the entire tube works easily and freely. The craftsmanship ensures that each tube is accurately matched to ensure that customers can use it with confidence.
