Abstract
383,545. Valve amplifying circuits'. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13D, Emmasingel, Eindhoven, Holland. April 21, 1932, No. 11469. Convention date, May 5, 1931. [Class 40 (v).] In order to prevent instability in neutralized pushpull amplifiers arising from the inductances of the leads interconnecting the electrodes of both valves (i.e. the filament connections and the anode-grid cross-neutralizing connections), the ratio between the impedances ofthe anode-grid connections and the intercathode connections corresponds to that of the anode-cathode and anode-grid capacities. This is effected as shown in the Figure by connecting the push-pull input circuit I to the electrical centres of the anode-grid cross-neutralizing leads ln, which include the neutralizing condensers cn.
