working out component values for bc108 preamp

working our component values for bc108 preamp

Hi I'm new here, i was given a load of BC108's to make a preamp. The guy who gave me them gave me a diagram of how i should connect the
components with one transistor 6 resistors and 2 capacitors. But he didn't tell me the values of resistors and caps. How do i work these values out?

I have put together some kits with ic's and they all work fine but i have only a vague idea of whats happening in the circuits. Can someone recommend a book or website that deals with designing amps from a beginners point of view?

thanks
