Linlai E 6sn7 tubes

Look close, those two tubes are made and shaped differently too.

-Flatter and wider top on the first one.

-Rounder curves, top corners, on the second one.

-Notched base on the second one. Smooth base on the first.

-internal top section looks a little different.

-different print obviously.

Hey @decooney, great observation there.   I guess the mystery continues...

Maybe the best thing to do is the send a message to Linlai Global and ask them if both are authentic Linlai tubes.

After re-reading their Buyer Beware page.  I'm beginning to think the lower picture posted by @twoleftears might be a copy.

@xcool The thing is, that second pic is from the Viva Tubes site.

Maybe @vivatubes can clarify why there are physical differences beyond just a branding issue.  

I know Linlai says there is a difference between eastern and western bound tubes, but I bought mine from a Chinese dealer and they look identical to the ones from Grant Fidelity, besides the logo is a little different, so maybe viva got some early issue tubes or later issues. I would be surprised if they weren’t both Linlai elite tubes.
