Linlai E 6sn7 tubes

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.

@lowrider57, 😁

I recently purchased 4 of the horizontal lettering tubes for my Atmasphere MP-1 preamp.  Unfortunately, I did not test them before I burned them in for 100 hours in my preamp.  The good:   They definitely sounded amazing (bigger 3D soundstage, and  smoother highs compared to my stock Chinese 6SN7s at the 100 hour mark. However; I tested the four of them afterwards and three of them tested on the lower end of the acceptable range (Using a B&K 747B tube tester) and one was questionable.  The questionable tube resulted in a solidly  lit DC offset light on my preamp; it obviously is out of spec and had to be removed.  So, not sure what is going on so buyer beware.  Would be interested to hear others feedback if they have tested their tubes and/or if they experienced similar issues with these similar pedigree tubes or the global elite vertical lettering versions

I hope you return them. Did you buy from an Ebay vendor?
