The Trafomatic Evolution One is one of the finest products in its class. Single Ended topology, no-negative feedback, Double-C core output transformers and top-notch power supply are just some of the ambitious specifications that Trafomatic Audio established as a de-facto standard for their amplifiers. With its design and sound quality the Evolution One will represent an easily recognisable style. It will bring a new dimension to your listening pleasure.

High quality output transformers built around Double-C geometry and 220VA EI M6 power transformer dominate the top plate of the amplifier. Oversized filter chokes inside underline quality construction throughout the unit. Vacuum tube rectifiers go without mention: direct heated rectifier 5U4G occupies central position in the tube lineup. Driver tubes are ECC81 coupled to the output stage via Solen fast capacitors. Power stage consists of two 2A3 EH gold grid tubes (one per channel). This specific variety has been chosen for increased dissipation capability and better musicality due to reduced third harmonic distortion.

Output power is 4W, therefore higher sensitivity speakers are recommended (95dB or higher). Gold plated robust input and output terminals are standard on every Evolution One amplifier.

ALPS volume control, Solen coupling capacitors, high reliability aluminium electrolytic capacitors and other quality parts ensure that sound quality is maintained throughout the amplifier’s life.

Standard colour is black, any RAL colour is available as an optional extra.
