( Brand: English Electric Valve ), ( Manufacturer Part Number: 8541A ), ( Type: Rectifier Tubes ), ( Country/region Of Manufacture: United Kingdom )
The 8541A English Electric Valve Electron Rectifier Tube is a vintage electronic component with a rich history in the field of radio and early television technology. This tube, manufactured by English Electric, is a rectifier tube, specifically designed to convert alternating current (AC) into direct current (DC).
The 8541A is a pentode tube, which means it has five active components within its glass envelope. The five elements include the cathode, grid 1 (control grid), grid 2 (screen grid), plate (anode), and a heater. The heater provides the necessary voltage to heat the cathode, which emits electrons. The control grid regulates the flow of electrons, while the screen grid strengthens the electron beam, and the plate collects the electrons, converting them into a usable DC current.
This tube measures approximately 9 inches in length and 1 inch in diameter, housing its components inside a seamless glass envelope. The 8541A operates on a voltage range of 300 to 350 volts and has a plate current of 30 milliamperes. It is designed to operate at temperatures between 25 and 65 degrees Celsius.
The 8541A English Electric Valve Electron Rectifier Tube is a valuable addition for collectors, hobbyists, and electronics enthusiasts working on vintage radio and television restoration projects. Its unique historical significance and functional capabilities make it a fascinating piece of electrical engineering history.
