The 4CV50,000E is also useful as a plate and screen modulated Class C rf amplifier.
| GENERAL DESCRIPTION |
|
The 4CV50,000E is a ceramic/metal, vapor-cooled power tetrode intended for use at the 50 to 100 kilowatt output power level. This tube is characterized by low input and feedback capacitances and low internal lead inductances. A rugged mesh thoriated tungsten filament provides adequate emission over the long operating life. It is recommended for use as a Class C rf amplifier or oscillator, a Class AB rf linear amplifier or a Class AB push-pull af amplifier or modulator. The vapor cooled anode is rated at 50 kilowatts dissipation. The 4CV50,000E is also useful as a plate and screen modulated Class C rf amplifier. |
