Abridgment of tuned radio-frequency amplifiers

A simplified method of calculating the performance of a tuned amplifier circuit is given and the effect of the various circuit constants on the characteristics is shown. The predicted results are found to check experimental observation quite closely. Curves showing the performance obtained with various types of tubes are also given. The factors affecting the stability are pointed out and typical methods for suppressing undesired oscillations are given, together with the principles involved.
