1. Tube body: This is made from a lightweight, durable metal, and it is tightly sealed at the ends to prevent air leaks. 2. Heat sink: This part of the tube helps regulate the heat distribution within the device. 3. Anode plate: This plate helps control the electrical currents running through the tube in order to maintain an optimal level of performance. 4. Getter shield: This plate acts as a "scavenger" to absorb any volatile gasses that would otherwise build up on the anode plate and alter its performance.
