It use the three transistor (2SC945, or 2C1815 or 2SC828) is main Which typical transistor amplifier with a low noise this circuit, too. There are about 200-300 times the gain. The frequency response is 50Hz to 100KHz. I have an old microphone, I want to make play with common amplifier. It does not sound much. Must to use pre amp before. I search a lot of circuits, see this circuits

it very well for me, low cost, use transistor. I would recommend a CanaKit UK494 Dynamic Microphone Pre Amp (Assembled Module). It is a DIY Kits available for use. I hope this guide is helpful for you.
