Microphone Transistors PreAmplifiers
Below exist two choices for preamplifiers of microphone that use transistor, in asymmetrical [ unbalance ] of input connection. For the supply of this stages, exist two choices. The first choice, are with diode zener, the other choice, use voltages that give the regulators, from main power supply.
