This is a high-end electronic tube amplifier, feeling substantial when held in the hand. Its main features are as follows:
- High Reliability: Equipped with additional top mica support to ensure transportation stability. High-grade anode materials and scientific design significantly improve the heat resistance of the anode. The highly insulated core stem design also effectively enhances the voltage withstand capability of the entire tube.
- CT Tube Manufacturing Technology: Adopts an extremely high vacuum pumping system, with a vacuum degree three orders of magnitude higher than other manufacturers. Free of gas molecules, it delivers extremely transparent sound with strong resolution. Scientific input, output and cross-road capacitance distribution greatly expand the bandwidth of TH212, ensuring excellent performance across 15Hz~2200Hz.
- Power Advantage: Delivers 6~8 watts more power than other TH212 tubes without the anode turning red during use.
- Sound Quality Characteristics: Brilliant high frequencies, full mid frequencies, good low-frequency extension, a fully expanded sound field, excellent resolution, rich harmonics, and powerful yet smooth driving force.
The filament (cathode) adopts a high-performance, vibration-resistant rhenium-tungsten cathode, providing 1.35 times higher emission current than ordinary thoriated-tungsten wires. This results in higher output power, richer details, more delicate sound, and better balance of treble, midrange and bass.
High-purity, high-frequency pure alumina ceramic produced domestically is used as the fixing bracket between electrodes, which greatly reduces electrode leakage, increases fixing strength, lowers frequency loss, and improves product sound quality.
The grid adopts a platinum-plated grid wire process, which effectively suppresses thermionic emission from the grid, brings the return grid current close to zero, and makes the sound purer and more transparent.
Anode: Custom-made precious metals such as iron-nickel-tungsten-zirconium from Italy are smelted in vacuum. The anode material is hundreds of times more expensive than that of other TH212 anodes. It features extremely high heat capacity and extremely low gas content. With a power dissipation capacity of 295 watts, it can withstand higher voltages and higher output power. The precious metal alloy anode makes the sound warmer, with flexibility embedded in its rigidity. As the TH212 tube with the highest power dissipation capacity currently available, it will never turn red regardless of usage, thoroughly ensuring product stability!
