( Brand: Westinghouse ), ( Manufacturer Part Number: 4HS8 ), ( Type: Nos Tube )
The Westinghouse 4HS8 Vacuum Tube is a remarkable piece of vintage electronics, harking back to a time when radio and early television sets relied on such components for their operation. This particular tube, the 4HS8, is a dual triode type, which means it can function as two separate triodes within the same device.
The 4HS8 is designed with a high plate current of 200 mA, making it suitable for use in high power applications. Its low plate resistance of 200 ohms ensures efficient power transfer from the grid to the plate, resulting in a high output power. The tube features a plate voltage of 300V, which is typical for high power vacuum tubes.
The 4HS8 has a frequency response that extends from 30 Hz to 15 kHz, making it suitable for a wide range of audio applications. The tube's shape is a familiar and timeless one, with a large glass envelope that houses the internal components. The two triodes are clearly visible within the tube, each with a set of metal filaments for heating.
In terms of physical dimensions, the Westinghouse 4HS8 has a diameter of 9.25 inches and a height of 5.5 inches, making it a substantial component. The tube weighs approximately 1.5 pounds, reflecting its robust construction.
In conclusion, the Westinghouse 4HS8 Vacuum Tube is a versatile and powerful component that offers a unique combination of high power and wide frequency response. It is a testament to the craftsmanship and engineering prowess of a bygone era, and remains a cherished piece of hardware for vintage electronics enthusiasts and collectors.
