( Brand: Ge ), ( Manufacturer Part Number: 6FH5 ), ( Type: Nos Tube )
The GE 6FH5 vacuum tube is a historical and iconic component in the world of electronics, particularly in the era of radio broadcasting and early television. This specific tube, manufactured by General Electric, is a pentode type, meaning it has five electron control grids, which allows for more complex amplification and signal manipulation compared to simpler triode tubes.
The 6FH5 tube measures approximately 9 inches in length and 3 inches in diameter, with a glass envelope enclosing the internal components. The vacuum inside the tube maintains a high vacuum pressure, which is essential for the tube's operation. Inside the glass envelope, you'll find five metal plates coated in a special material, such as oxide or aluminum, which serve as the control grids. The heart of the tube is the cathode, a filament that glows when heated, emitting electrons.
This 6FH5 tube is known for its excellent performance in high-frequency applications, such as audio frequency amplification or audio frequency oscillation. It can operate at a plate voltage of 300V to 400V and a plate current of 50mA to 150mA. The tube's high gain and low distortion make it ideal for use in audio amplifiers, where it can provide a rich, warm sound.
The GE 6FH5 vacuum tube is a testament to the ingenuity and technical prowess of the past. Despite being an older technology, it continues to be appreciated by enthusiasts and audiophiles for its unique sound character and historical significance. Whether you're restoring a vintage radio, building a tube amplifier, or simply have an appreciation for vintage electronics, the 6FH5 tube is a must-have component.
