Linlai E 6sn7 tubes

@rocray that video is what caused me to buy the premium matched Psvane CV181 MKII set which comes with the harder case box with foam encasing inside for each tube vs. the paper thin individual box versions sold to dealers in large lot boxes. While that video was said to be an ultra-peak busy day, it gives imagination of what a chaotic sorting center can be like there. I tracked my last package deliberately, it sat in facilities around there for 4-5 days before it went onto a plane over the pond into the USA. Was scanned over 20 times from origin to destination to give u an idea. Shipping damage a likely culprit on D.O.A tubes. TJFM concluded this too a few years ago so they started doing even better packing and boxing since.  

BTW: guessing over 120hrs on the PSV 181 MKIIs, as transparent as can be now.

My Linlai’s came in a “display” box as well.  The contoured foam inside ensures a tight and safe journey.  I know how packages can be handled. I’ve just never seen them stacked like a mountain before. A couple extra bucks is definitely worth the added protection.  @decooney, I’m glad the Psvane’s are working out for you. It’s great that there are alternatives to NOS tubes.  

I did hear back and the sellers were closed due to Covid for a week. I am told they are sending me another pair. Stay tuned.

So, I popped the top on my fine Black Ice hybrid preamp, removed the TungSol tube and popped in a Linlai 6SN7. After the tube warmed up, it is clear that it was an upgrade. More tonal saturation, more meat on the bones so to speak which was my only issue with the stock tube that came with the preamp. It had great clarity and soundstaging but was a touch more lean sounding than my tastes.

@jaymark, let the Linlai burn in for around 100 hours.
