... BA3402 The BA3402 is a dual preamplifier developed for auto-reverse car tape decks. An electronic switch on the chip switches between the forward and reverse heads, and this has the benefits of greater reliability, easier wiring, lower space require- ments, and improved assembly efficiency when compared with conventional mechanical switches. The circuit is de- signed in such a way that coupling capacitors are not required ...

... Audio ICs (4) Capacitor for prevention of oscillation and RF mix- ing With the BA3402, a capacitor must be connected be- tween each input pin and the bias pins to prevent oscilla- tion and RF mixing. The recommended value for this ca- pacitor is 1000pF to 2000pF too small, oscillation and RF noise can adversely influence circuit perfor- mance ...
