This is the circuit diagram of a 1W audio amplifier with TDA7052 as the main component and 5 other components supporting the main components. The ideal supply voltage for this circuit is about 6-12V and no heat sink is required. The schematic is for mono, just build two similar circuits for stereo channels.
Element:
R1: 1K ohm resistor
R2: 10K ohm logarithmic potentiometer
C1: 2.2uF/16V electrolytic capacitor
C2: 100nF ceramic/mono
C3: 100uF electrolytic
TDA7052 integrated circuit
8-pin IC socket
