The Evolution Line One is a full tube preamp from the new Trafomatic Audio Evolution series. The model was created as a partner for the Elegance Evolution power amplifier. At the same time, it turned out to be a difficult task to create a preamp that matches the quality of the existing Evolution series models. As in all previous developments, Trafomatic Audio engineers relied on the principles of minimal use of active elements and the selection of the highest quality passive circuit elements.

    Trafomatic Audio Tara 30A

    Trafomatic Audio Tara 30A tube preamp: balanced dual mono and external power supply. Tara 30A, the new Trafomatic Audio linear preamp, is based on a pair of EML30A lamps in each channel, with custom nanotransformers at the output of each of them. The 6N30P dual triodes operate in the pre-stage. To compensate for chassis vibrations and prevent microphone effects, each EML30A received its own independent spring suspension. Arrow millivoltmeters and "dynamic balance" adjustment potentiometers are installed on the upper panel of the device, allowing you to adjust the operating parameters of the circuit.
