The Gu-43B is a vintage Russian military tetrode vacuum tube, a type of electronic device that was once crucial in various electronic applications, including radio and early television sets. This specific model, the Gu-43B, is a unique piece of electronic history, hailing from the Soviet Union's military electronics industry.
The Gu-43B is a tetrode vacuum tube, which means it has four electrodes: the cathode, anode, grid 1, and grid 2. This configuration allows for more complex amplification and signal control than triodes, making it suitable for a variety of high-power applications.
The Gu-43B is a medium-power tetrode, with a rated plate voltage of 300 volts and a plate current of 100-150 milliamperes. Its anode dissipation is 2.5 watts, making it a relatively efficient vacuum tube for its time. The Gu-43B operates on a frequency range of 200 Hz to 30 MHz, making it versatile for use in a wide range of radio frequency applications.
Physically, the Gu-43B is a cylindrical glass tube, approximately 11.5 cm in length and 3.5 cm in diameter. The tube is filled with an inert gas, typically argon, which helps to prevent the filament from burning out and to prevent the internal components from being damaged by high temperatures.
The Gu-43B is a collector's item and a fascinating piece of technology history. Its unique design and historical significance make it a desirable addition for electronic hobbyists, vintage radio enthusiasts, and those with a passion for the evolution of technology. Whether you're restoring a vintage radio, building a retro amplifier, or simply interested in the history of electronic devices, the Gu-43B is a must-have component.
