• 125W plate power.
• Full ratings operation up to 30MHz
• Up to 120MHz at reduced input
• Also used as Class B modulator.

The grid of the 805 is designed so that the amplification of the tube varies with the amplitude of the input signal. This feature facilitates the design of Class B A-F amplifiers and modulators to give high output with low distortion.
