Stereo Pre-Amplifier Kit
Velleman Part Number: K2572
This it is a universal low-noise stereo pre-amplifier (preamp). It is useful for boosting small signal level audio sources to work with line-level inputs on tuners and amplifiers. This kit is easy to assemble with an easy to follow instruction/assembly guide and only a handful of components. It can be powered from a range of DC voltages (10-30VDC) and has low power consumption.
This kit is based around the Texas Instruments TL072CP Low Noise JFET Op-Amp IC. Input, Output and power are supplied to the preamp by means of solder posts located beneath the blue plastic shroud.
