The 87722 tube is a unbased vacuum tube, meaning it does not have a metal plate inside the glass envelope to control the flow of electrons. Instead, it relies on the shape and design of the internal components to control the electric current. This design was used in various applications, including radio frequency amplifiers and oscillators, due to its ability to handle high-frequency signals with minimal distortion.
The glass tube itself is a work of art. It is made from high-quality borosilicate glass, which is known for its strength and resistance to thermal shock. The tube is cylindrical in shape, with a narrow base that tapers into a wider bulb. The bulb is where the internal components, including the filament, grid, and plate (if applicable), are housed.
The exterior of the tube is coated with a protective enamel paint, which is usually a dark color to help absorb any stray light and prevent it from interfering with the operation of the tube. The tube is also marked with various labels and numbers, including the part number D-87722, which helps identify the specific type of tube.
