This Hi Fi stereo preamplifier circuit is built with TDA1054 IC from SGS. TDA1054 is a 16-pin DIL package and integrates 2 separate preamp circuits. It is a low noise preamp with little or no problem ...

Over the years I’ve become a student of mic preamp design, building and modifying several along the way and learning a little more each time. Usually, I worked from a kit or published set of plans.

A preamplifier circuit with a very low noise characteristic can be built by simply combining a FET transistor with a bipolar one. The input impedance of the preamp circuit is almost the same as the ...
