PRE-AMP MIC CONDENSOR SIMPLE SCEMATIC DIAGRAM

This circuit uses low noise transistors are type types: BC 650 C but the transistor is hard to find, so you can replace it with 109 BC is no less good. This condenser mic element in it is a very sensitive microphone, and to use this mic condenser required voltage between 2-10 volts, for that we can resistors in series with 1K-10 K ohms, in the picture above the tide 1k ohms.
