Linlai E 6sn7 tubes

I received my Viva purchased Linlai E 6SN7s and they look fantastic. They have a nice gold text label, the serial numbers inside the glass, and the insides look identical to Global and Grant Fidelity Linlai 6SN7s. Through conversation with Viva it is my understanding that the manufacturer has done a couple of in-production changes, therefore, some batches may look slightly different. I am installing these this weekend and will more than likely enjoy what I hear. I am keeping them. Enjoy. 

Hey @vivatubes, thanks for clarifying.  Can you let us know why your company is not listed in this Reseller Locator page at the Linlai Global website?

@markusthenaimnut  Thanks for your wise counsel.  I doubt its speaker placement or twitter issues as I had a musical paradise 702 Mk 2 preamp before purchasing the freya+ and it did sound pretty decent. You are perhaps right. I just need to let the JJs burn in before investing other tubes. Maybe its just early now and the tubes need to be seasoned. Thanks for sharing your thoughts.

Last night I was listening to music, and decided to do a little experiment.  I shut everything down,and waited a few minutes.  I then preceded to put the Linlai’s back in the system to verify the bad tube and mark it.( since I had failed to do so the other evening.)   After putting them back in,they have worked flawlessly.  I am thinking in my haste,I didn’t seat the tubes correctly?? They have about two hours on them since trying them out again. Not a peep out of them, but great music.  Anyone care to speculate what the heck is going on over here?  At this point,all is not lost,as I have a back up pair on the way.

@rocray a bit after I first got my 6sn7/cv181-TII psvanes, something similar happened. 1st time I tried them, fine out of the box. Later had removed them with barely 10-12 hrs on them. A few weeks later I re-installed them, at startup for about 45-60 seconds I heard this fuzzy sound, grainy, mildly static, as if some of the internal coating had flashed off or something, maybe barely arching with small particles floating around. Went away after 3-4 minutes of warmup at startup. Same thing happened with some small signal/driver vintage true NOS tubes from Brent Jesse. Intermittent static, a few pops. He had me pull them, tap them on the counter bottom/pins side down, 3 taps, and put them back in - and cured, gone. He shared maybe some micro burned off particles floating around with these new/un-played tubes would settle at the bottom of the tubes, fwiw. No issues since on the new output tubes or the older nos input tubes since. No clue if anything like this is related to yours, sharing a similar type experience. Pull, lightly tap-tap-tap, re-install. Happy listening. 👍
