Très bons tubes
Utilisés sur un ampli de puissance Conrad Johnson MV52 en remplacement de JJ Tesla KT77 (avec environ 600 heures de fonctionnement). Je trouve les médiums plus chaleureux et le grave plus tendu. J'avais auparavant des Electro Harmonix 6CA7 qui avaient de très beau médiums, mais des graves pas assez vivants à mon goût. Je suis donc très satisfait de mon achat.

Tubes pentodes TUNG-SOL EL34B (quad appairés)
Achetés pour remplacer un quad d'EL 34 Electro-Harmonix qui m'ont donné satisfaction depuis 12 ans... Je suis extrêmement surpris par le message musical de ces tubes. Chaque instrument est à sa place: les aigus ne sont pas agressifs, les basses sont profondes sans excès , les médiums clairs . comparés aux EH, la finesse est en plus. Pas de fatigue à l'écoute et les voix sont superbes. Les TUNG-SOL sont transparents du haut en bas, chauds avec une tonalité splendide. Pour l'instant en rodage sur un ampli de 2x35w. A recommander. Merci à l'équipe pour ce choix. Jean-Philippe.

Tung-Sol EL34B Matched
I replaced the vacuum tubes on my PrimaLuna Evo 400 integrated amplifier, the result is fantastic. The musicality has increased noticeably, the sound is much more balanced especially in the mid and high range. Let me start by saying that the hours of use are few so it can only improve. I highly recommend these EL34 TungSol.
