Linlai E 6sn7 tubes

I've been following this thread, and particularly the discussions about where to buy them and differences between sources, with some interest.  I wanted to share my experience.  I bought a set of LinLai E-6SN7 tubes off ebay from seller atop_authentic_auctions.  I choose him because of the low price and 30 day return policy with seller paying for returns.  I ordered on May 31st and tubes came today.  As you can see from the pictures in the link below the tubes were very well packaged and I was particularly impressed by the corner protectors on the box.  Logo is horizontal and doesn't say "Global".  There is a metal plaque inside the tube with the details and serial number.  Tubes came with test scores and were closely matched.  I've had them running for less than an hour but they are silent and sound great so far.  I have not compared them the the Sophia Electric Blue Glass that I had in my Aric 300B amp before but first impression is they certainly aren't any worse and may be significantly better.  I'll do comparison testing after the tubes have burned in for 25-30 hours.

Based on my limited experience so far I would say all of the concern over "Global" branded tubes versus tubes not branded for the overpriced export market is probably misplaced.

Thanks for chiming in. You can see how confusing this has been and it took some collaboration to figure things out. I agree with you, is the SQ of the Globals really worth the increased cost? But, after all the research we’ve done here, I’m dying to find out.

@pinwa You are right on that count. I agree as well. Tks for sharing your impressions.  Glad it sounds great so far.  Cool looking amp too. Possibly getting my non Global Linlais soon, hope by the end of the week.  Looking forward to it.

@lowrider57 ;

Yes. I ordered my 4 GLOBAL tubes from LINLAI’s web site & if you recall they said, NO outbound shipping from China, due to the virus, so they sent my order to an oversea distributer. ’’Grant Fidelity’’ Now being that I didn’t make a deal with @bugredmachine for to keep those tubes. I don’t have a set to compare, but I did hear a change in sound in my system. I’m going to post picture’s when they come today. After the initial evaluation, I’m going to hook up my Don Sachs to my Pioneer 1280 to burn in for 24/4. That should bring them up to 100 hrs.

Here's a crazy idea, perhaps an owner of a Don Sachs preamp could contact him and ask if he's compared the Linlai Globals with the E-6SN7 Chinese domestic. After his Shunguang supplier closed, he must have auditioned several types of tubes.
