The 8930 is electrically identical to the 4CX250R/7580W but the larger anode radiator assembly allows higher dissipation with low air flow and pressure drop characteristics. The tube has rugged internal construction features for reliable operation under heavy shock or vibration conditions. Characteristics Plate Dissipation (Max.) Screen Dissipation (Max.)
