Abstract

371,443. Valve amplifying circuits. RYALL, L. E., 159, Westmead Road, Sutton, Surrey. Jan. 23, 1931, No. 2292. Drawings to Specification. [Class 40 (v).] A diode or static contact rectifier may be employed in the anode circuit of a thermionic valve in order that the anode voltage may correspond more closely to the applied grid voltages at the bends of the characteristic curve.
