Start with reading and digesting "The Art of Electronics", by Horowitz and Hill. By the end of that you should be in a position to start.

You need to design for a certain power output into a known load, decide on a topology, A,B or D (C are for RF only), decide on supply rails, and input sensitivity. You may not NEED a preamp, but you can do useful signal conditioning, noise filters etc there.

thanks.will read up on it.
the project topic is with the pre amplifier but will discuss this with my supervisor
