I have a microphone from a pretty old phone that is ceramic. I have an old police speaker that has a resistance of 8 ohms. I would like to use 9 volts. I am in dire(?) need for a circuit that will amplify the sound produced when talking into the mic. I'm looking for suggestions or schematics on how I will go about doing this. Note: It does not have to be a 9v circuit. Another Note: I will be using this in an area where it may be quite loud, so the louder the better. Thank you so much!!!
