Abstract

1,162,816. Transistor sawtooth circuits. ELECTRIC & MUSICAL INDUSTRIES Ltd. 21 Nov., 1966 [19 Nov., 1965], No. 49151/65. Heading H3T. In a line deflection stage for a dual-standard television receiver, the supply voltage to terminal 6 is arranged to be reduced when the circuit is operating on the lower (405) line standard, components 8, 9 being included to prevent breakdown of the output transistor 2 by higher amplitude flyback pulses caused by the reservoir capacitor 7 temporarily retaining the previous higher voltage when changing to the low frequency standard.
