Linlai E 6sn7 tubes

I agree with you @decooney. There could be numerous reasons for that partnership to dissolve.  The quality thing has stuck in my mind. Rightfully so? I can’t say.  But I know there are Psvane dealers that do offer 12 month warranty on their tubes.  I guess that wasn’t enough to sway me. Yet….

@immatthewj, I’ve dealt with some reputable tube sellers on EBay.  There are some(what I feel) are great deals on NOS measuring tubes for very reasonable prices. 

better stock up guys, Taiwan looks like pretty easy pickings for someone at the moment…

Too bad the Linlai 6sn7 is so huge. I’d like to try it but my amp takes two pairs and they’d be too close together for proper ventilation. Perhaps Linlai will make a more sensibly-sized version someday and dramatically expand their market. Hint, hint if you’re listening, Linlai.

My 1948 Raytheon 6SN7 tubes are about the same price now at Linai per AiiExpress.   I chose them over Ken-Rad (very close) and RCA from the 40's to 50's era of 6SN7 as they had the best package of dynamics, warmth, extension, etc.   I'm using them as cathode followers in mono-block amps.   It's amazing how much difference there is in cathode follower use (the Sovtek which rebranded U.K. and Counterpoint were awful, the Sylvania Chrome domes were really open and fast but totally too bright from my amps).   I wonder if the Linai's will last 5,000 or 10,000 hours?   Has anyone used or compared Sophia Electrict 6SN7s?   They are even more expensive.

I had done just a little research on the Sophia Electric Blue glass,and they seemed to be highly regarded,however there were none to be found. I have no idea about the longevity of the Linlai’s. If I’m still around,I’ll report after 5-10K hours of use. LOL!
