Abstract
PURPOSE:To reduce the impedance of the screen grid of an electron tube, by interposing a transistor (TR) and a bias resistance between the screen grid and two bias resistances determining the bias value of the screen grid. CONSTITUTION:Between two bias resistances 2 and 3, determining the bias voltage of the screen grid 11 of an electron tube, and the screen grid 11, a TR7 and a bias resistance 8 are interposed. Thus, the input impedance of a TR circuit 14 is increased exteremely and the output impedance is decreased extremely, so that impedance of the screen grid 11 is decreased to suppress low the variations of the bias voltage of the screen grid 11.
