This Audio booster circuit is very simple and can be applied to fm tuner or audio pre amplifier. The 2N3392 is a low-noise type transistor in TO-92 case. The transistor can can be replaced by a NTE199 or ECG199. If you wish to use a TUN, cross reference the parameters with one of the units from this list : TUP-TUN Potentiometer R5 of 100K is a linear type with an on/off switch attached. The value of C1 may need to be between 0.05µF and 0.1µF (47nF/100nF). Experiment with the value for best performance.
