Linlai E 6sn7 tubes

Hi @marco1, no worries! I was a little confused. I think the quality issue you’ve experienced is not uncommon when purchasing from overseas sellers. I was very fortunate getting two sets of tubes without issues. In the grand scheme of things,I would think that the manufacturer would want to clean this situation up.  Folks like you that are turned off by horrible quality control, will not throw good money after bad,trying to chase a good set of tubes. That’s not good for anyone. I’m sorry to hear you had the same issues with Psvane Summits.  I was thinking of giving them a try at some point. I guess I’ll have to rethink spending the money on them. 

@rocray actually it was a well respected US seller.  I’ll refrain from naming names as I think it’s a tube problem. You can PM me for specifics if interested.  It seems you as well as many others have had good luck with these tubes so I may try again in the future in case the seller happened on a bad batch.

I just received a pair of Linlai E-6SN7 this afternoon. I'm using them in my Linear Tube Audio MicroZOTL preamp.

They've only been playing for a couple of hours, but I really like them.  Only drawback is they are too large to fit through the top of the preamp. I may have to leave the top off. 

@sls883 I have the tube extenders on my Don Sachs pre, using the Global E & LOVE them. I recently purchased the LTA Aero DAC & purchased a set of Global Es. Burnt them in @ 20 hrs & didn't like the sound. To muddy, so they'll stay in my stash for future use.
