shared wiring

This is a circuit for signal tracer. This circuit is work with based on LM741. This is the figure of the circuit.


This is a high gain amplifier circuit that can be operated from a battery pack of 6 or 9 volt battery pack. The IC1 uA 741 is wired as a high gain non-inverting amplifier and its output is amplified by a pair of complementary transistors (Q1 & Q2) to drive the speaker. The negative feedback from the common emitter junction of the two transistor stabilizes the gain of the circuit. The resulting audio output is sufficient to serve as a signal tracer. The POT R6 can be used as a volume controller. All capacitors must be rated at least 15V.
