Remplace judicieusement des 12AX7 sur mon preamp phono tubes
Achetés pour remplacer 2 tubes 12AX7 GoldLion de qualité mais à forts gains, sur mon préampli phono Yaquin MS-23B, avec des risques de hs sur les atténuateurs de volume de mon ampli ATOLL IN200 Signature, j'ai choisi ces tubes 12AY7 sachant que j'aurais près de 40% de gains en moins mais une meilleure précision dans les micro-détails. Le pari est plus que gagnant !

UPGRADE DU CANAL GAin MARSHALL DSL 5 CR
Acheté pour remplacer la 12AX7 d'origine du préamp de canal ultra gain de mon marshall, afin de le rendre plus progressif : le résultat est notable, on retarde d'environ1.5 graduation la plage de réglage avant le durcissement typé "marshall" de la saturation. cela permet de trouver un réglage plus "crunchy" en début de course. (j'ai aussi testé une 12AT7 WA : effet moindre, pas suffisant)
