Linlai E 6sn7 tubes

The global ones have the logo vertical and the eastern ones have it horizontal, but the internal structure looks the same, except for the ones from viva tubes.

I don't think you can use that as a reference any more. Mine came from Don Sachs's distributor and have horizontal lettering. And the amptata_audio website has horizontal lettering on all tubes.

My E-6SN7's have a serial number inside the bottle. All authentic Linlai's do. I wonder if Viva's tubes have it.

This is the email I received from Viva tubes this morning;

Hi Dan, they are indeed legitimate. We import them directly from China. Thank you for your order. We hope you like them.

I called earlier, with no response. I’d like to know if these tubes are legitimate, or are they copies? Dan M.

I just sent them an e-mail too. They are not taking calls: 

"Good morning,

I have a question after reading that Grant Fidelity was also selling the new Linlai E 6SN7 Global tubes. They look different and have different branding than the ones you are selling. Are the Linlai E 6SN7 that you sell the same tubes but have different batch manufacturing which makes them look different?  I want to ensure that I am receiving the new Linlai Global tubes as depicted in the manufacturer's site: Linlai™ Global Elite E-6SN7 Vacuum Tubes (pair) – LINLAI™ Global Vacuum Tubes (linlaiglobal.com)

If these are not the same tubes, then I would like to return them as I thought I was ordering the Global Linlai edition, and not the Globe version which you are selling. It seemed to me a little confusing because you sell these with the word Globe in the selling title, which I assumed also meant the new Global versions. If these are not the same, I would like to start the return process based on me ordering the wrong tubes. Thank you. 

I use these tubes for the output stage of my CD player. They replaced a set of insanely-expensive Brimar CV-181 tubes that were damaged in a tragic feline accident. Probably 1/3 the price and equally-wonderful sound quality.
