4CX20000B-EI  Transmitting Tube, Tetrode, Broadcast / Industrial, MFR: Eimac

The 4CX20,000B is intended for use as a Class C RF power amplifier in AM broadcast service, for use as a push-pull audio amplifier or modulator, or as a pulse modulator. The anode is rated for 20 kW dissipation and incorporates a highly efficient cooler of new design, which significantly reduces air pressure and flow requirements and produces low acoustical noise.

4CX20000D  Transmitting Tube, Tetrode, MFR: Eimac

The EIMAC 4CX20,000D/9015 is a ceramic/metal VHF power tetrode intended for use as a RF amplifier up to 110 MHz. It is particularly recommended for use in the 88-108 MHz FM band. It features an electromechanical structure which provides high RF operating efficiency and low RF losses. The 4CX20,000D has a gain of up to 20 dB in FM broadcast service. The anode is rated for 20 kilowatts of dissipation with forced-air cooling and incorporates a highly efficient cooler of new design, which significantly reduces air pressure and flow requirements and produces low acoustical noise.

3CPX5000A7 Transmitting Tube, Triode, Broadcast / Industrial, MFR: Eimac

The 3CPX5000A7 high-mu triode is designed for use as a cathode driven Class AB pulsed power amplifier and as a switch tube in cathode or grid driven service. The tube does not require a socket as it is designed to bolt directly to the chassis be means of the grid flange. Cathode and heater connections are made by bolting directly to the amplifier circuitry. These features reduce equipment cost and complexity.

3CX15000A7 Transmitting Tube, Triode, MFR: Eimac,  No longer available for Export (NOS)

The 3CX15,000 A7 is a high-mu power triode intended for use as a zero bias Class B RF amplifier or Class C power amplifier or oscillator. It is also recommended for use as a grounded grid FM amplifier. Class B operation with zero bias offers circuit simplicity. In addition, grounded grid operation is attractive since a power gain as high as twenty times can be obtained.
