Linlai E 6sn7 tubes

@xcool , I ordered from LinLai in China & they sent my order to G/F.

Yes I purchased the top of the line, "ULN" so there was no 2nd guessing.

OK, I see.  Thanks @danmar123.    

Just to refresh my evaluations. The bottom line is: I had the 2 different tubes at the same time. There is a difference between the Global & the non Global in my system. Why don't members just try for themselves @ the cost of return shipping. This would stop all the inane posturing that's being discussed about these tubes. This weekend I changed Carts on my GAE from Hana ml (240) hrs. to my Cadenza Black (83) hrs. on an SME 309.

With the Globe's, my system has NEVER sounded so good. I have K/R, Sylvania JAN & Tong Sols, tried every combo & with the 4 Global in my Don Sach's their staying.

@danmar123  Maybe I missed an earlier post, but this is the first definitive proof I've read about the difference between Linlai tube types. I don't think there was any posturing going on, only speculation.

Thanks for weighing in.

And after buying so many NOS and "almost NOS" during the tube panic, I couldn't afford an expensive pair of Linlai Globals.
