Tell me more!

The European Triode Festival brings together some 100 high-end vacuum tube audio lovers from all over the world: from Finland to New Zeeland and from Italy to The US. At the Festival participants demonstrate their all home-built equipment (analogue/digital/amps/speakers/etc.) and discuss all aspects of high-end vacuum tube sound reproduction. During the 2 days of the Festival, several seminars, workshops, shootouts and musical performances are organised.

Previous seminar speakers have included people like Jean Hiraga, Morgan Jones, Lynn Olson, Per Lundahl (Lundahl Transformers), Brian Sowther (Sowther Transformers), Steve Bench, Guido Tent (Tentlabs), Allen Wright (VSE), Peter van Willenswaard (Stereophile), Pieter Treurniet (Tribute Transformers), Tim de Paravicini (EAR/YOSHINO) and John Boskie (TubeCAD).

Previous workshops have included subjects such as power supplies (shunt/series/passive/regulated), the sound of distortion, noise and hum, speaker crossovers and digital jitter.
Shootouts have included items such as phono stages, full range speakers, single ended triodes and output transformers.

Previous ETF's have been reviewed in several magazines, including Revue du Son, TNT Audio, 6Moons and Prestige Audio Video.
