Linlai E 6sn7 tubes

I wonder if Viva got a bad batch all from the same lot (giant box o’ tubes), rattled apart or something maybe from a dropped box in shipping from afar. Who knows, they’ll have to answer to you’all on that. Over the years had good luck with them, however also started purchasing from different individual suppliers who test or test/listen to tubes before shipping them out. Seems like varied quality right now. Like what @lowrider57 said, "band of brothers" giving feedback and forcing their hand a bit will help, a message of seeing to folks getting their refunds taken care of first.

Xcool go for Grant Fidelity it’s worth the price, don’t cut corners on tube.

More likely they were a backdoor purchase or worse. Not the same build and they are called by a different name. Even Ali Express, which Linlai has declared illegitimate, uses the correct name of the tubes.

The internal structure doesn't look the same on the tubes from viva.

@invalid if so. the ones I'll get tomorrow their going rite back.

I called Viva this morning and left a message for them to call me. If I don't hear from the by the end of the day, their going BACK!
