A feedback-stabilized vertical-deflection circuit

This paper describes a feedback-stabilized vertical-deflection circuit that makes use of a transistor oscillator to drive an output tube. The circuit possesses a few innovations that overcome some of the deficiencies that exist in conventional vertical-deflection circuits. These innovations include improved interlace over the lock-in range, increased independence from variations in output-tube characteristics, true height adjustment, and picture height regulation for color.
