1.274B is a high-performance rectifier tube, which adopts special cathodic electrophoresis process. The surface is smooth and firm, and has sufficient emission current. It is exhausted for a long time by ultra-high vacuum exhauster. The vacuum degree inside the tube is 5U4G. It is more than 100 times higher, and at the same time, it adopts the method of high pressure long refining to improve the stability of the whole tube.
2. The tube can withstand the anti-peak voltage of 850V or more, and its output DC current is 150MA. It does not cause sparking when working under high pressure. It is an ideal rectifier tube and can be used as a rectifier. selected.
