Be extra careful - Quality Issues

Deeb 1 09.06.2026

I bought a matched quartett to replace the same power tubes in my amp.

Replaced and biased by a pro tech, within 2 months, the amp started crackling sounds due to a faulty power tube, generating sparks.
This wasn't bad luck as I had a similar issue with the EL34s of the same brand, which i had to return as well due to a wrong match 27 to 48 :(

Guter Sound zum angemessenen Preis

Tigerworx 09.01.2022

Das TAD 6L6GCM-STR Red Matched Quartett sind der Hammer. Qualität und Sound zum angemessenen Preis.

Die 5881er Röhren in meinem 1992er '6100 LM MARSHALL' 100 W Master-Vol sind durchgepfiffen. Schon gewundert, wie lange die halten. Statt 5881er hab ich das kompatible Quartett eingesetzt. Die Valves sind länger, passen aber gut unter die gefederten Röhren-Fixierer.

Alter Schwede ! Hätte ich schon eher machen sollen: Fett - Warm - Kaftvoll.
Höhen kommen gut, Mitten ausgewogen. Daß der Bassbereich dünn sein soll, kann ich nicht bestätigen. Die JCM 900 Lead 1960 Box macht da gute Arbeit. Einstellungs-Sache. Egal ob meine 71er Paula oder die 68er Strat, beide gehen richtig gut los.

Schon im satt angesteuerten Clean-Bereich blasen einem die 4 Valves den Sound nur so um die Ohren.
Fazit: Qualität, Verarbeitung, Sound, Preis: Okay. Kann ich wirklich empfehlen.

Tons of Juicy Gain ^^

Steeve_Julius 09.06.2021

en remplacement des 2 paires de mon ENGL 840/50
le son est monstrueux !!! une attaque de malade 3>)
moins de basse que dans les Tung-Sol/ENGL mais perso je prefere ^^
car les basses on peut toujours en rajouter dans le Preamp en amont et le son a plus de niaque avec celles-ci ...ca tend un peu vers la EL84 en fait dans les aigues...

Funcionan bien en mi Jet City

shattered 22.02.2025

Buenas válvulas, dan un buen sonido con el amplificador Jet City y son las que recomienda TAD en su sitio web, las ajusté para que estén todas entre 30 y 35mA como recomienda TAD.

Esta vez no venían tan bien emparejadas como otras veces, con 1-2.5 mA de diferencia, pero no es nada grave y volvería a comprarlas. No producen hum ni ningún problema que haya podido apreciar.
