Linlai E 6sn7 tubes

@rocray "He said they are very close to the Shuguangs."

I've heard similar from a colleague yet want to test it myself too, later. I've been following some of the musical chairs discussion about some design engineers bouncing from one factory to the next. After the founder of TJFM passed, some tooling was reportedly sold to PSVANE for their line of small signal tubes including CV181/6SN7s. They were making re-labeled tubes for at least 3 others, privately.

After watching GF drop PSVANE Premium pairs directly for Linlai, I wrapped up testing quads of TJFM 6SN7s this last year - ordered a pair of the newer PSVANE matched CV181-TIIs this week sourced directly overseas, someone i used prior. 

Would like to eventually compare the newer version PSVANE II to the Linlai version after I sell off some other stuff.

Keep us posted @rocray after some good burn-in occurs. Thx

@decooney, I remember reading about the Grant/Psvane thing a while back. That being in the back of my mind,held me back from ordering a pair of the blue globe 6sn7’s. 

At the moment, I am looking for an upgrade from my stock EH 6SN7s, but I am afraid that these are quite a bit out of my price range.

I'd love to hear 'em, though!

Yep. I truly wondered if the matter had something to do with other financial or buying power factors vs. quality issues. As we’ve seen, vendors, resellers, drop manufacturers for reasons many of us will never know about. I’ve learned to make my own evals, particularly if there is a mid-level seller involved in that chain.

These folks get super competitive too. While I read unvalidated feedback from anonymous folks stating "it only lasted a year", I’ve found the opposite with my older TJ Full Music 6SN7s and new PSVANE small tubes 12AU7, 12AT7s still going strong. All my good 60s Mullard Blackburn plant nos/vintage stuff is stored away in boxes now. Re-visting PSVANEs in other tube types is next for me. Its what AN is using too, in their own private batches. You keep up the good work with Linlai too! Nice.

Ask: keeping each other updated and informed here, I’ll trust this more.

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.
