Abstract :
A new approach for obtaining the audio power required for high-level plate modulation of AM broadcast transmitters is described. The advantages of this system are lower initial cost, broader frequency response, lower distortion, transmitter output adjustable from zero to full output, lower power consumption, fewer amplifier tubes, and lower operating cost.
