This is the circuit diagram of stereo preamplifier which built based a compact ic tda1524a. For maximum performance, better quality, use solid capacitors or film capacitors and metal film. This contains all the circuitry required to provide up to 20 db of voltage gain.

It is probably the one of the easiest audio amplifiers to build.

With this, we can covert sound energy to electric energy and amplify it a bit with the help of the preamplifer. It is extremely easy to construct due to the use of a special ic, the philips tda 1524a. view universal preamplifier circuit diagram. Simple bass boost circuit diagram.
