Pretty nice little tube :)

Midwinter Apathy 27.10.2026

It works better than Tung Sol or Sovtek ones I've tried. It also got rid of some of the hum I've had, so... I'm happy with my purchase. :)

Good lamp

Kaz2 04.01.2023

I have a Fender blues junior IV and a Koch Jupiter 45, both using 12AX7/ECC83 lamps.
The lamps sound fine, and I agree with the description on the Thomann website. Lamps are a bit like guitar strings, they loose some highs and lows when used so new lamps always should sound better, even if you replace them with the same make and type of lamp. Anyway, good product for your money and both amps are like new again.
The installation went ok on the Blues Junior.
On the Koch, the socket of the lamp is about 3cm below the surface of the amp protection box. Here I had to take the amp out because the pins on these lamps are very soft and bend with the slihtest movement. I can imagine that these can break of easely if you don't handle them with care.
The delivery and handling of my order was perfect as always with Thomann. One remark for Thomann: They came in a box the was to big. As a result they where not well wrapped and could fly around in this box. Wrapping up lamps for transport need a bit more attention!

Testé et approuvé

Pat Orla 07.08.2025

J’ai relampé 4 préamps gtr / multieffects vintages de mes collections (Digitech, Rocktron…) que j’ai révisés et entretiens régulièrement.
J’ai utilisé ce modèle et marque de tube à vide pour remplacer mes dernières et vieillissantes mises à niveau (EH, Ruby, sovtek, et autres)
Testées dans plusieurs styles et configurations en répétition et en studio.
Pour qui cherche la finesse et la clarté, surtout en configuration dual et réglage du gain de chaque tube à part dans les presets, c’est lumineux.
Net changement, les sons clairs sont transparents et précis, les saturations sont nickels et réagissent plus finement à l’EQ, pas brouillons ni trop acérées.
Tubes pas loin de la hi-fi de par leur clarté, sans bruits de fond ou hum.
Pour un ampli préamp d’amplis GTR je ne sais pas, j’ai toujours utilisé du Sovtek modèles d’origine preconisé.
Je pense que ces tubes sont surtout utilisables pour du rack préamp studio ou scène avec amp de puissance ou direct console avec simu HP (à l’ancienne) mais à tester.
Pour l’instant je valide.
Pour la longévité on verra dans quelques mois.
