5AT8 Tubes

1. Cathode: This is the heated electrode of the tube which supplies the electrons that are used for the flow of current. 2. Plate: This is the metal plate that collects and regulates the amplified electric current that passes through the tube. 3. Screen Grid: This is a grid of wires between the plate and the control grid that is used to shield the plate from changes in the control grid's electric field. 4. Control Grid: This is the grid of wires that is used to control the flow of electrons through the tube by varying the voltage applied to it. 5. Anode: This is the electrode connected to the plate and used to emit excess electrons that are not used in the tube's operation. 6. Base Connector: This is the electrical connection at one end of the tube used to connect the tube to other components in the circuit. 7. Heater/Filament: This is the electrical element inside the tube which is used to heat up the cathode and produce electron emission from it. 8. Pins: These are the metal pins at the other end of the tube used to connect the tube to the power source, control signals, and other components in the circuit.
