6 volt amplifier

Low voltage amplifier intended for battery powered applications. 2 Common Emitter stages and an emitter follower buffer for lower output impedance. The real circuit I built using these exact component values gave a gain of around x100 flat across the audio spectrum (-3db points being @ around 10Hz and 571Khz. I used bc549c for all of the transistors.
The gain can be varied by adjusting the emitter resistors, for maximum gain the emitter resistors can be bypassed with a 1000uF capacitor. This will also increase distortion.
