Common emiter amp

Can i increase the output power of this common emiter circuit....?     I think it can be done by increasing the collector current.......      then the problem is whether the Qpoint of the bias can be changed ....  ( as ic divided by current gain to get the base current)
...      if it will be occur  the amp whould not  be bias......  please help me to  understand that..........   who can describe it better please help

You need a DC decoipling cap between AC source and switch. Just take 1uF for the first step. After that decouple all caps and tune collector voltage to about half supply voltage 5V. Tune the lower input resistor to about 2.9kOhm. After than change input peak voltage to less than 1V and wire all caps again. Hope this helps a little.
