This circuit was found in Italian magazine (1988), but can be mounted with ease even with the changes and exchanges of components made by us. The circuit is interposed between a signal source and the input of an amplifier serving as bass booster. One application is in home theater, feeding a woofer. The source must have excellent filtering and consumption is very low. The TL081 IC admits equivalent and can be used any operational with FET. Input cables and output signals must be shielded.
