This circuit [Fig.1] is a class AB stereo audio power amplifier designed by Quasar for quality hi-fi applications using a TDA2005 module. It is easy to construct and has a minimum of external components. The module has output current protection and thermal protection. This is circuit, which produces an excellent sound. The supply voltage required 9V-18V DC at 1 to 2 Amps. Maximum output power will only be obtained with a power supply of at least 2A at 15V DC, and using 2 Ohm speakers or 2 by 4 Ohm speakers in parallel. However approximately 4W/ch. can be obtained with only a 15V DC, 1A supply into 4ohm loads..
