I have just purchased an antique phone that has no circuitry other than wires leading to the microphone and earpiece. Can anyone suggest some minimal wiring that will smooth out the signal a bit? It is very peaky. I know that there is some kind of variable resistor in most phones that performs rudimentary compression on the signal. Can anyone help out? -cliff
