I did'nt think of trying a different microphone other than an electret.Dang,wish I had kept the circuit now.Live and learn I guess.I looked at chemelc's website.I LIKE THAT ONE.I noticed he had a plan to use a speaker as a microphone.The thought of more area coverage is appealing but I might have to sacrfice sensitivity.If I used the speaker-as-microphone circuit instead of a electret mike and given the speaker was an 8 ohm load,would the circuit,once built,have an output of 8 ohms or would the load be higher like that of an electret microphone?I was reading the text under the schematic I attached.The gain is determined by the sum of the 2 transistors' hfe,which are 242 each(hfe1+hfe2=484)times the ratio between the input and output load.The output being 10k.So would'nt a lower load(the 8 ohm for example)make the gain higher since there is a greater ratio between the input and output?Man,this is fun!!!!
