LIN LAI tube Stunning new work hook (hook fixed filament) series of power tubes launched


     As we all know, like the bile duct of the same model, the sound of the metal screen is more transparent than that of the graphite screen. The same structure, the process of fixing the filament with a spring, is not as fine and vivid as the process of installing the filament with a hook. This is a fact!

    Throughout the current world, the existing and in production 845, 211, 805 bile ducts are basically the installation process of using graphite screen or metal screen and spring hook to fix the filament. The 845, 211, and 805 bile ducts with graphite screen or metal screen and hook filament structure have not yet been seen.
     The process of fixing filament by hook is a very complicated and extremely difficult production process. Because of his installation fulcrum and the height of the gap, the width and parallelism of the left and right are very particular. The hardness, resilience, elongation and expansion coefficient of the hook material are also related to metal materials and theoretical mechanics. A little carelessness is a waste, and the yield rate is certainly not exaggerated! Generally, bile ducts of the same model basically use the process of fixing the filament with a spring hook, and the process of installing the filament at the fulcrum of the hook is used for the high-end products. The price of the finished product is far from each other, as much as dozens of times. The reason can be seen and it is reasonable.

      "Lin Lai's Voice", the latest development of 845, 211, 805 bile ducts with graphite screen and metal screen plus hook filament, and succeeded in one fell swoop! It is a great gospel for tube amplifier industry and tube amplifier enthusiasts.

       845-DG, 211-DG, and 805-DG use traditional graphite screens, with three heat dissipation windows on each side of the screen, which have extremely high heat dissipation and thermal stability, and the electron emission capability and working life are greatly enhanced. And for the first time, the process of fixing the filament with a hook is used to make the filament relax in the working state, and the sound is more transparent and vivid. In order to reproduce the magnificence and atmosphere of the sound field, the outer diameter of the glass bulb was increased, and the top of the glass bulb was supported and fixed by a ring-toothed mica sheet.

Experienced players on the 845-DG test and hearing evaluation:

Tested with the electron tube test scanner imported from Germany: 1000 volts at high voltage, 80 mA screen current, 80 watt-hour screen consumption. Main parameters: Distortion> 1%: output power 20 watts, signal-to-noise ratio 97db, tube white noise 0.01 Milli v.


Suggestion: when using single-ended output power tube: select 950-1000v for screen voltage, adjust screen current to 60 to 70 mA, control screen power consumption at about 60 to 70 watts, load impedance 5k-7k is the most reasonable, and the sound is the best , The output power is about 16 watts. After the parameter measurement is completed and the aging is stable for 48 hours, the 845 bile duct of the new hook filament is compared with other high-end 845s. Although there is basically no difference between the parameters of the hook filament and the spring hanging filament on the instrument, the sound But there is a world of difference. Only then can you understand what is called "beauty salon plastic surgery" and what is called "natural beauty"! Although the traditional 845 bile duct is different in tone and sense of hearing, perhaps the "body" will be gorgeous, but the feeling is all the gorgeousness of the "facelift". As soon as the 845-DG of the hook filament comes on stage, it gives people a real, elegant, real, amiable, and refined atmosphere. Fresh, quiet and natural beauty, accurate notes, one-by-one playing technique, it seems to be vividly visible, the reverberations and overtones that come to an end, the calm playing style is breathtaking! If it is said that the traditional old 845 generally has the low frequency too stable, the mid-frequency line is slightly less positive and the high frequency is slightly "introverted", it will be swept away by this 845. Many tube amplifier enthusiasts like the unique mid-to-high frequencies of 300B and WE212 with "squeaky" and "squeaky" sounds. This 845 is better than that, but it adds a mature, stable, and pleasant charm to people. Can't stop. Moreover, the 300B low-frequency foot is soft, the frequency distribution is uneven, and the criticism of lack of confidence has been swept away from him! It can be considered that the sound of the 845 bile duct is very similar to that of the 300B, but the bloodline is filled with the stability, atmosphere, and noble temperament of the royal family, which is more durable than the 300B and WE212.

After passing the 845 test parameters of this model of metal screen hook filament and comparing it on the machine, my personal conclusion is: this is the best one I have heard of all the various models of 845. In particular, enthusiasts who like to play 300B and WE212 bile ducts can finally find an ideal sound path.

The launch of Lin Laizhiyin's hook series power tubes will completely change the cognition of 845, 211, 805 power tubes among fans! People-friendly prices, stable quality, luxurious listening, and high-quality after-sales services are Lin Laizhiyin's commitment to the market! It's so manageable, it's worth having!
