The 4CX1500A is recommended for use as a Class C power amplifier, Class B or Class AB, linear amplifier as a regulator, and in pulse modulator service.
| GENERAL DESCRIPTION |
|
The 4CX1500A is a general purpose tetrode for use up to and through VHF. Insulation is ceramic and the thoriated tungsten filament is a rugged mesh design. The screen terminal is a continuous ring which allows good isolation between the plate circuit and the control grid circuit. The 4CX1500A is recommended for use as a Class C power amplifier, Class B or Class AB, linear amplifier as a regulator, and in pulse modulator service. |
