Linlai E 6sn7 tubes

@pinwa had great luck mixing them up, I was surprised. But yeah those stock tubes are horrible. I think people sell them with the stock tubes because they never used them. 

All I can say is I put a pair of Linlai 6SN7-E tubes in my Audio Mirror Reflection monos a couple of days ago and WOW. What great tubes, period. Not even begun to break-in. I immediately ordered a back-up pair. Every thing said here about them is correct, at least in my system. 

Same here. Added two to my Cary preamp and just the two for the balanced output and noticed an immediate change. Nice airy highs and separation. 
 

ordered a quad that will arrive Monday and will have all 6 tubes be the Linlai. Excited. 

Been leaving my preamp on for the past few days as these are pretty dark at first as everyone has said. Looking forward to them burning in a bit. 

That's good to hear, where did you get them?  From reading this thread I was under the impression that the Global Elite from Linlai and Grant had a different base, the ones in the pictures on their sites.

I think that tells me that the only difference between the cheaper versions straight from China and the ones from Linlai is that you might get a better version that's been screened.......but who knows.

After a year of discussions about Linlai and owning two pairs of the E-6SN7, I have a theory. The Chinese market and the tubes for the West are the same. Here it is, the glass blowing creates a standard shape, the assembly line builds and inserts the internals into the tube. A vacuum is created and the getter receives a jolt causing it to flash. The bottle is sealed and doesn't need the base yet and the loose wires are ready to be soldered into the pins once a base is mounted. Two different bases can be used depending on the destination, the same goes for different branding on the bottle.

Does this sound crazy or very simple to accomplish?
