The black glass bulb 6SN7 is a current high-end Teana product made by Shuguang Electron Tube Factory. Choose the best materials, use the best design, the best technology, and rigorous production in a dedicated boutique production line. A long-screen anode and a long cathode are used. The inner surface of the glass bulb is sprayed with high-purity single-crystal carbon, which expands the heat dissipation area, increases the heat dissipation speed, and makes the sound quality more pure. The high frequency is bright, the middle frequency is deep and the low frequency is powerful. The sound field background is quiet, well resolved, accurate positioning, rich in details, and gentle and durable.
The coating can shield the external clutter interference and return the sound field to the natural charm.
