A stereo tube preamplifier based on 6K4 tubes. It allows you to change the volume, adjust the bass and treble, and give a "sweet" color to the sound characteristic of devices with vacuum tubes. The parameters are regulated by means of three potentiometers located in the front part of the housing. The preamplifier allows you to connect two audio input channels via RCA connectors and outputs in the form of active speakers or an amplifier with passive speakers. It is powered with the voltage of 12 V and can consume up to 1 A.

Due to the standard sockets, the user can replace the 6K4 tubes with others, e.g. 6J1, 6J2, 6J4, GE5654 or 6AK5, to modify the preamplifier operating parameters. The electronic module was placed in a nice, aluminum housing. The FX-AUDIO Tube-03 is a good choice for both novice users and audiophiles.
