( Brand: General Electric ), ( Manufacturer Part Number: 6BE6A ), ( Country/region Of Manufacture: United States ), ( Type: Electron Tube )
The 6BE6A General Electric electron tube is a vintage and highly collectible vacuum tube that was once a staple in the world of radio and early television technology. This particular tube falls under the category of triode-pentode types, which means it can function as both a simple amplifier and a more complex device capable of controlling the intensity of multiple signals.
The 6BE6A tube measures approximately 8.5 inches in length and 2 inches in diameter, with a base diameter of 1.25 inches. It features nine metal pins, including three control grids, a cathode, and five anodes, which allow for a wide range of applications. The tube operates on a high voltage, typically between 250V and 350V, and is capable of handling currents up to 350mA.
The 6BE6A tube's glass envelope is a sturdy Pyrex material, which is known for its resistance to thermal shock and chemical reactions. The tube is coated with a metal layer for added protection and insulation. The inside of the tube is filled with a low-pressure inert gas, such as argon or neon, which helps to prevent the electrical discharge from the filament from causing damage to the tube's internal components.
The 6BE6A tube was widely used in the mid-20th century for applications such as audio amplification, oscillator circuits, and signal mixing. It was particularly popular in high-fidelity audio systems due to its ability to provide high-quality sound with minimal distortion. Today, the 6BE6A tube is highly sought after by collectors and enthusiasts interested in vintage audio equipment and electronics.
In summary, the 6BE6A General Electric electron tube is a versatile and iconic piece of vintage technology. Its unique design, high voltage operation, and wide range of applications make it an essential component for any vintage electronics enthusiast or audio aficionado.
