    1997-1-15 · screen-grid modulated amplifier. Screen grid modulation is, by its nature, efficiency modulation. If you have the amplifier set for, say, 75% efficiency at full output (four times carrier), your efficiency drops to 37.5% at carrier level. On the other hand, if you have a modern Class AB2 amplifier your efficiency at full output will be about 65%.

  • Vibrating Screen Working Principle - 911 Metallurgist

    2019-1-3 · This resistor determines the amount of audio supplied to the screen grid. Self-modulation of the screen works because screen current varies with anode voltage. The screen system, in effect, becomes a constant current supply for the screen grid. As the plate modulator pushes anode voltage higher, screen current decreases. Decreased screen current causes screen voltage to increase.
