I'll keep visiting the thread and gathering others assessments on the Tube comparisons and options to consider when the system is re-established and in use.

I also like the idea of using these Tube Types with adaptor sockets in place of

ECC 88's on other owned devices.

“May I check if the Linlais you were referring to as detailed are Linlai Globals with vertical letterings or Linlai E6sn7  with horizontal letterings as @lowrider57  has outlined. As you may have read in this chat, there are different impressions between these two tubes”

These are Linlai E-6SN7 Globe with horizontal lettering. These are the ones I purchased. Is there a difference in sound between these and the GF ones? 

@audioquest4life Apparently Yes. If you go up the thread, there has been a lot of discussions about this. @danmar123  feels there is a difference. Some have found the non global Linlais pleasing. Others like @lowrider57 do not feel its up to mark.  You can check out the posts. I have purchased similar tubes as yours  and am still burning it in. 

Viva says they are an authorised dealer, but these tubes are not the Global Elite from Linlai. I bought the same tube on Ebay, horizontal lettering and ridge in the bass. Compare these to the Elite on Linlai’s site; large vertical logo and a smooth base with no ridge.

And Viva is not referring to them by their proper name. They list them as

Linlai E-6SN7 Globe-Balloon Black Plates.

I would love to hear the Global Elite, but they’re as expensive as a good pair of NOS tubes. If I sell my E-6SN7’s from the dealer in China, maybe I’ll order from Grant Fidelity.

Everyone here is free to do as they choose. I'm simply trying to prevent members from being taken advantage of by unscrupulous vendors.
