( Brand: Ge ), ( Model: GL-7038 ), ( Type: Vacuum Tube ), ( Country/region Of Manufacture: United States )
The GL-7038 Vacuum General Tube, manufactured by General Electric (GE), is a valuable addition to any vintage electronics enthusiast's collection or a crucial component for military restoration projects. This tube is a testament to the engineering prowess of the mid-20th century, with its robust construction and reliable performance.
The GL-7038 is a triode vacuum tube, a type of electron tube that has been an essential part of electronic devices for over a century. It operates on the principle of thermionic emission, where electrons are emitted from the filament due to its high temperature. The electrons then pass through the grid and are amplified before reaching the plate, which further amplifies or regulates the signal.
The GL-7038 is a 6.3mm (1/4") pin base tube with a filament voltage of 6.3V and a plate voltage of 300V. It has a maximum plate dissipation of 15 watts, making it suitable for applications that require moderate power. The tube measures approximately 7.1 inches in length, 1.6 inches in diameter, and weighs around 10 ounces.
The vacuum inside the tube is maintained at a very low pressure, ensuring that the electrons move freely between the filament, grid, and plate. This vacuum also helps to reduce noise and improve the tube's lifespan. The GL-7038 is made from high-quality materials, including a ceramic base, a tungsten filament, and a metal grid and plate.
The GL-7038 Vacuum General Tube by GE is a piece of history that still holds practical value. Its unique sound and character make it a popular choice for audio enthusiasts who appreciate the warmth and depth that vacuum tubes bring to music. For military restorers, this tube is a crucial component in maintaining the original functionality of vintage military communication equipment.
In conclusion, the GL-7038 Vacuum General Tube is a testament to the ingenuity of mid-century engineering. Its robust construction, reliable performance, and unique sound make it a valuable addition to any vintage electronics collection or military restoration project.
