The Western Electric 403A is a pentode tube, which means it has five electrodes: a cathode, an anode, and three control grids. This design allows for a high degree of signal control, making it ideal for use in audio amplifiers, radio receivers, and other high-fidelity applications.
The 5654 variant of the 403A is a low-mu (mu-meter) tube, which means it has a lower gain than some other pentode tubes. This makes it well-suited for use in power amplifier stages, where it can deliver high power levels with minimal distortion.

Physically, the Western Electric 403A is a large, heavy tube that is easily recognizable by its distinctive glass envelope. The tube is cylindrical in shape, with a diameter of approximately 2.75 inches and a length of around 5 inches. The tube is sealed in a glass envelope that is filled with an inert gas, which helps to prevent the tube's internal components from burning out.
The Western Electric 403A is a true workhorse of vintage audio technology, and it is still used today in many high-end audio systems. If you are looking for a tube that can deliver rich, natural sound with power and precision, the Western Electric 403A is a great choice. Whether you are restoring a vintage audio system or building a custom audio amplifier, the Western Electric 403A is a tube that will not disappoint.
