Abstract

844,423. Valve circuits for radio reception; muting. LOEWE OPTA A.G. Sept. 10, 1958, No. 28981/58. Classes 40(5) and 40(6). In a television receiver the sound channel is silenced until the receiver becomes fully operative by deriving the screen-grid and/or anode potential of one or more I.F. stages from the booster diode 10 of the line timebase, As shown the screen-grid and anode of valve 1, which comprises a sound I.F. stage are fed, via series resistors 8, 7 respectively and a common R.C. circuit 11, 12 of long time-constant from one end of the primary 9 of the line transformer.
