Abstract

661,782. Valve amplifying circuits. SOC. INDUSTRIELLE DES PROCEDES LOTH. March 30, 1949 [April 2, 1948], No. 8613/49. Class 40 (vi). The maximum output obtainable from a screen-grid or like valve used as a cathode-follower is increased by driving the screen-grid in phase with the output voltage, by means of a stepup auto-transformer 19.
