ーダーの再生回路。 A first tape recorder having a playback function and a second tape recorder having a recording and playback function are built into the same cabinet, and a dubbing function is provided for recording the signal played by the first tape recorder with the second tape recorder. In the tape recorder, a recording/playback switch that is switched to the recording side during the recording operation of the second tape recorder, a dubbing switch that is switched to the dubbing side during the dubbing operation, and a high-speed dubbing switch that is switched to the high-speed side during the high-speed dubbing operation;
a control transistor that is conductive when in a high-speed dubbing operation state; a switching transistor whose base bias is controlled by the control transistor; and an inverting operation of the switching transistor that is connected to the base circuit of the switching transistor. a time constant circuit for slowing down the magnetic field; a reproducing magnetic head that is built into the first tape recorder and that performs a reproducing operation; 1. A reproducing circuit for a tape recorder comprising a first capacitor and a second capacitor connected in parallel to the reproducing magnetic head when the switching transistor is in a conductive state.
