TRANSIENT SUPPRESSION FOR TAPE PLAYERS INTEGRATED CIRCUIT PREAMPLIFIER Abstract of the Disclosure In a tape player the preamplifier integrated circuit can produce a transient, when the player is turned off, that will impress itself on the head thereby recording a noise signal on the tape. A circuit is shown for suppressing such transients. A diode is connected in series with the power supply so that when the player is turned off, the diode disconnects the pre- amplifier from the power supply. In addition a large value filter capacitor is connected across the preamplifier terminals so that the applied voltage can change only at a relatively slow rate.
