This product is completely designed according to the original RCA211
High transparent lead-free large glass shell design not only accelerates the heat dissipation effect in the tube, but also makes the whole tube more beautiful
Imported high-purity and high-density vacuum smelting graphite materials to increase the dissipation power of the anode by 20% compared with similar products. The exquisite processing technology reflects the extraordinary value
High-efficiency thorium-tungsten cathode imported from the United States can not only ensure large dynamic distortion, but also overcome the weakness of other manufacturers' filament breakage.
Platinum grid, at higher working temperature without any grid radiation phenomenon
The positive tolerance design of the conductive rod and the anode, there is no situation that the core is skewed due to work flashover or transportation
The lengthened pure gold tube needle design makes her and the tube seat hug tightly without any signal missing.
Maintain and exceed the sound characteristics of the original tube
The pins and sockets of the sounds of Teana series are all plated with real gold (24K). They can withstand the salt experiment test, and they will not fade or fade for ten years, and have good conductivity.
Completely maintain and exceed the sound characteristics of the original tube
.Precise matching, no parameter drift
