Does anyone have a schematic, or link to a schematic, that is useful for building a reliable and simple intercom.

I have two 8 ohm speakers I would like to use as loudspeakers and mic's. These are old computer speakers.

Thanks
 
just use a powr op amp each end for receiving and a op amp as a preamp for the mic each end. fiddle with the gains till you get the right volume.
