Tape Head Pre-Amplifier




Description

The circuit is built around a popular Sanyo’s stereo head preamp IC LA3161. Low electrical signals from the playback heads are fed to pins 1 and 8 of IC1 via DC decoupling capacitors, respectively. Components between pins 2 and 3 and pins 6 and 7 provide adequate equalization to the signals for a normal tape playback.
