This is a preamplifier and tone control unit that makes a perfect match for an amplifier kit. It is extremely easy to construct due to the use of the Philips TDA 1524A. It contains all the circuitry required to provide up to 20 dB of voltage gain, +/-15 dB of bass and treble, channel balance and a switchable loudness contour.
