The vapor-cooled anode is rated at 100 kilowatts of plate dissipation when mounted in the BR-300 series boiler.
| GENERAL DESCRIPTION |
|
The 4CV100,000C / 8351 / FD003Z is a ceramic-metal, vapor-cooled power tetrode intended for use at the 100 to 200 kilowatt output power level. 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 4CV100,000C / 8351 / FD003Z is also useful as a plate and screen modulated Class-C rf amplifier. The vapor-cooled anode is rated at 100 kilowatts of plate dissipation when mounted in the BR-300 series boiler. |
