ID: 845-vacuum-tube

The 845 is a type of vacuum tube (or electron tube) that was originally developed in the 1930s. It is a power triode, meaning it has three electrodes: the cathode, anode (plate), and control grid. The 845 tube is known for its high power handling capabilities and is often used in audio amplification applications, particularly in high-fidelity and high-power audio amplifiers.
