Hook Silk Lin Laizhi Voice 211-DG/845-DG/805-DG Electronic Tube

As we all know, like the same type of bile duct, the metal screen is more transparent than the graphite screen. With the same structure, the process of installing and fixing the filament with a spring is not as fine and expressive as the process of installing the filament with a hook. This is a fact! Throughout the current world existing and production of 845, 211, 805 bile ducts are basically the use of graphite screen or metal screen and spring hook to fix the filament installation process. The 845, 211, and 805 bile ducts made of graphite screen or metal screen and hook filament structure have not yet been seen in the world. The process of fixing the filament with the hook is a very complicated and difficult production process. Because of its installation fulcrum and the height of the gap, the width and parallelism of the left and right are very particular, the hardness, rebound strength, elongation, expansion coefficient, etc. of the hook material are also related to metal material science and theoretical mechanics. A little carelessness is a waste product, and it is no exaggeration to say that the yield is one in ten! Generally, the same type of bile tube basically adopts the process of fixing the filament with a spring hook, and only the high-end boutique adopts the process of installing the filament at the fulcrum of the hook. The price of the finished product is very different, to dozens of times, which shows the reason, and it is reasonable. "Lin Laizhi", recently developed 845, 211, 805 bile tubes with graphite screen and metal screen and hook filament, and they succeeded in one fell swoop! It is a great boon for the tube amplifier industry and tube amplifier enthusiasts. 845- DG, 211 -DG and 805-DG use traditional graphite screen electrodes, with three heat dissipation windows on each side of the screen electrode, which have high heat dissipation and thermal stability, and greatly enhance the electron emission capacity and working life. The filament is fixed by hooks. The technology makes the filament in the working state relax and the sound is more transparent and vivid. In order to reproduce the magnificent sound field and atmosphere, the outer diameter of the glass bulb is increased, and the ring-shaped mica sheet is used to support the fixed tube core on the top. .
