Review PHILIPS/AMPREX/RAYTHEON/WF 5651/0g3/85a2 Lot Of Tested 5651/0g3/85a3 Tube Voltage Reference Vacuum

The Philips/Amperex/Raytheon WF 5651/0G3/85A2 and WF 5651/0G3/85A3 tubes are high-performance vacuum tubes, specifically designed for use in various electronic devices such as radio receivers, television sets, and other analog electronics.

The WF 5651 tubes are triode vacuum tubes, which means they have three electrodes: the cathode, grid, and plate. The cathode is the negative electrode that emits electrons, the grid is a control electrode that regulates the electron flow, and the plate is the positive electrode that collects the emitted electrons.

The WF 5651 tubes have a filament voltage of 6.3V, which is typical for vacuum tubes of this type. The filament is the heating element that provides the necessary energy to create the thermal electron emission from the cathode.

These tubes are designed to operate at a plate voltage of 250-300V, which is the voltage applied to the plate electrode to accelerate the electrons and amplify the incoming signal. The plate current can range from 100mA to 1A, depending on the specific application and operating conditions.

The WF 5651 tubes are made of high-quality materials and are designed to withstand a wide range of operating temperatures. They are also well-known for their excellent stability and reliability, which makes them suitable for applications that require high-performance and long-lasting performance.

In conclusion, the Philips/Amperex/Raytheon WF 5651/0G3/85A2 and WF 5651/0G3/85A3 tubes are high-performance vacuum tubes that offer excellent stability, reliability, and performance for various electronic applications. They are designed to operate at a filament voltage of 6.3V and a plate voltage of 250-300V, with a plate current ranging from 100mA to 1A. These tubes are made of high-quality materials and are well-suited for applications that require long-lasting performance and high stability.

1. High-quality design and manufacturing: These tubes are known for their excellent performance and durability, which are a result of the high-quality materials and careful manufacturing process.
