The Westinghouse VR-105-30 0C3 Vacuum Tube is a classic piece of electronic engineering, harking back to the golden age of radio and early television. This particular tube, manufactured by Westinghouse, is a triode vacuum tube, a type that has been instrumental in the development of communication and entertainment technology.
The VR-105-30 is a direct-heated triode, meaning it uses a filament to heat up the cathode, which in turn emits electrons that are controlled by an applied voltage. This tube has a plate heater, which is a separate filament that heats the metal plate, also known as the anode. This design allows for a more stable and efficient operation of the tube.
The Westinghouse VR-105-30 0C3 Vacuum Tube is a versatile component, suitable for use in a variety of amplification applications. It has a plate voltage range of 225V to 300V and a plate current of 4 mA to 10 mA. The tube's internal construction includes a nickel-alumina oxide cathode and a barium-strontium oxide coated plate. The glass envelope is sealed to maintain a vacuum inside, ensuring proper operation of the device.
In summary, the Westinghouse VR-105-30 0C3 Vacuum Tube is a historical and functional piece of electronic equipment. Its direct-heated triode design, versatile voltage and current specifications, and high-quality construction make it a valuable component for those restoring or building vintage audio equipment.
