... Dual preamplifier with ALC BA3306 The BA3306 is a dual preamplifier with ALC designed for use in stereo radio-cassette recorders and tape recorders. It comes in a compact 9-pin SIP package and has two record / playback preamplifiers, and an ALC circuit. The preamplifi- ers have high gain and low distortion, and can be directly coupled to the tape head without coupling capacitors. This prevents tape head magnetization and “ ...
