Abstract

678,689. Valve amplifying circuits and apparatus. PHILIPS ELECTRICAL INDUSTRIES, Ltd. April 17, 1951 [April 20, 1950], No. 8993/51. Classes 40 (v) and 40 (vi). In a neutralized push-pull R.F. amplifier employing pentodes 1, 2 parasitic oscillations are suppressed by an inductor 14 connected between the suppressor grids and earthed over a capacitor at its centre. The capacitor may comprise the strip 14 mounted on insulators 16 on an earthed plate 15.
