TUNG-SOL 12AU7 / ECC82 Tubes Military Quality (Unit)

TUNG-SOL 12AU7/ECC82 Tubes Military Quality (Unit)
The Tung-Sol 12AU7, manufactured in Russia, ensures very low noise. It has been designed to mimic the performance of American NOS 6189 tubes. This one proposes an open restitution certainly audiophile, but will also work very well for the design of an amplifier guitar, this one supporting very well the distortion.

J'ai acheté ce tube pour mon ampli casque hybride Bravo Audio Ocean. C'est le 3ème tube que j'achète pour remplacer celui d'origine (origine inconnue). Pour mes oreilles et mon matériel (casque Grado SR325) le Tung-Sol est le meilleur des 3. Je vous donne mes impressions d'écoute des 3 tubes:
- JJ Electronics: Du punch et belle extension de la réponse en fréquence (pour un tube). Utile si votre système manque d'aigu.
- Electro-Harmonix: Superbe médium mais manque de punch sur le reste de spectre.
- Tung-Sol: fourmillement de détails et grand naturel.
