( Brand: Western Electric ), ( Model: 701A ), ( Country/region Of Manufacture: United States ), ( Type: Vacuum Tube )
The Transmitting NOS Tube, specifically the Western Electric 701A TU-1 Tetrode, is a vintage electronic component that holds a significant place in the history of audio technology. This tube is a tetrode design, which means it has four active electronic elements, including three control grids and a plate.
The Western Electric 701A TU-1 Tetrode is a Triode Underloaded (TU) version, which means it has a higher plate resistance than the original 701A. This design is particularly useful in high-power applications where the tube is required to operate with a lower plate voltage. The TU-1 version allows for a more efficient use of the tube's power, reducing the risk of plate overheating and extending the tube's lifespan.
The Western Electric 701A TU-1 Tetrode is a high-gain, high-mu (mutual conductance) tube. It is known for its excellent linearity, making it ideal for applications where precise signal amplification is required. The tube's high gain allows for a significant reduction in the number of amplifier stages, reducing complexity and cost, while maintaining high-fidelity audio output.
The 701A TU-1 Tetrode is a New Old Stock (NOS) tube. This means it is a tube that has been manufactured and stored in the past, but has never been used in a circuit. NOS tubes are highly sought after by audiophiles and vintage electronics enthusiasts for their superior sound quality, which is often considered to be superior to that of modern tubes due to their pure, unaltered design and materials.
Physically, the Western Electric 701A TU-1 Tetrode is a large, glass-encased tube with a distinctive octagonal shape. It features six metal pins for connection to the power supply and signal circuit. The tube is built to a high standard, with the glass envelope and metal components all made from high-quality materials.
In conclusion, the Western Electric 701A TU-1 Tetrode is a powerful, high-quality audio tube that is ideal for use in amplifier circuits where precise signal amplification and high gain are required. Its NOS status ensures that it delivers the pure, unaltered sound that vintage audio enthusiasts value so highly.
