The audio amplifier circuit is a class B amplifier audio power with a TDA1010. It is easy to build and has only a few external components. The circuit is designed with a short circuit and thermal protection. You can drive loads as low as 1.6 ohms and is capable of 10 watts deliveringover from an external 16 V DC.
The TDA1010 is a monolithic integrated circuit class B audio amplifier in one place-9 in line (SIL) plastic container. The range of voltage across and the flexibility of the IC to be an attractive proposition for turntables and tape recorders with outputs of up to 10 W.
