High Gain Mic Pre Amplifier


The best and cheap Pre-Amp circuit to make Microphone more sensitive to pick voice, although I had made one already but thought it worth try as it has nice gain around 100 as the author stated with a new chip TL071 which is low voltage high gain amplifier IC.

A little modification I made as you see some extra components are basically power supply using regulator chip LM7809  as I need it to run with 12V DC. This stand alone 9V regulator can be found here...
