Abstract

1,037,738. Magnetic tape recording; producing bias signals. THOBN-A.E.I. RADIO VALVES & TUBES Ltd. May 4, 1965, No. 18843/65. Heading G5R. In magnetic recording apparatus having an audio output valve 10 for playback, an oscillator comprising a transistor 20 and a transformer 21, 22 is connected in the cathode circuit of the valve to supply bias and erase signals so that during recording the audio output valve can be used for monitoring while its cathode supplies power to the oscillator.
