Single Transistor - 15 Db Audio Amplifier
This is a relatively simple project using spare parts that any good tech should have in his/her junkbox.

The selection of the transistor is not critical. Any small-signal transistor will work, just pay careful attention to the pin-configuration. Also it must be a NPN bipolar device. I have converted the absolute values for the caps and resistors to standard types. All resistors are 1/4w 5%, all caps are 20V. This circuit serves well as a small pre-amp, and can be "cascaded" very well to create more stages. |
