( Brand: Raytheon ), ( Model: RK-60 ), ( Type: Rectifier Tubes ), ( Country/region Of Manufacture: United States )
The RK-60 1940s Raytheon full-wave rectifier tube is a vintage electronic component that is a true testament to the bygone era of tube technology. This particular tube is a Raytheon-manufactured RK-60, a model that was widely used in various electronic applications during the 1940s.
The RK-60 is a full-wave rectifier tube, which means it can convert alternating current (AC) into direct current (DC) without the need for a center-tapped transformer. This makes it an efficient and versatile component for power supply applications in a variety of vintage electronic devices, such as radio receivers, amplifiers, and oscilloscopes.
The RK-60 tube is a dual triode design, featuring two active elements within the same glass envelope. Each triode has its own set of grid, plate, and cathode connections, allowing for multiple functions within the same tube. The tube is rated for a maximum plate voltage of 350 volts and a maximum plate dissipation of 1 watt, making it suitable for use in low-power applications.
Physically, the RK-60 tube is a large, glass cylinder with metal base and metal cap. The base is threaded to allow for secure mounting to a chassis, and the cap contains the high voltage connections for the plate and cathode. The tube is powered by a negative DC supply, which is applied to the cathode through a metal socket.
In summary, the RK-60 1940s Raytheon full-wave rectifier tube is a valuable and interesting piece of vintage electronic technology. Its dual triode design, full-wave rectification capabilities, and low power rating make it a versatile component in a variety of applications. Its large size and vintage appearance make it a charming addition to any vintage electronics collection.
