The 3CX1500D7 is a compact, high-Mu triode with an anode dissipation rating of 1500 Watts. This power grid tube features high gain and operates with zero bias in class AB2 as a linear amplifer or, with simple cathode bias, it provides good efficiency in class B and class C. A single 3CX1500D7 will replace two 3-500Zs in many applications. Class of Operation Characteristics Anode Dissipation (Max.) Screen Dissipation (Max.) Grid Dissipation (Max.)
