Is that the CV181-T, or CV181-TII ?
My understanding the Treasure II variant is the Carbon grey glass which is marketed as more refined than the black.
The same store I linked above for the Psvane TII "Classic Version" also list a slightly more expensive Psvane CV181-TII "Collection Version", from previous series Psvane sells a "factory select and matched" Collection version of their best tubes.
This is one area I dislike their convolution tactic.The same store I linked above for the Psvane TII "Classic Version" also list a slightly more expensive Psvane CV181-TII "Collection Version", from previous series Psvane sells a "factory select and matched" Collection version of their best tubes.
I'm not sure if a single tube from the "Collection version" is woth the extra, but if it is a select tube it might be worth a few more bucks.
Also, this Psvane series are called "Art Series", not Treasure - The Treasure name is used by Shuguang for many of their top tube models. Although I have seen US sellers mix up the naming in their listings, maybe they think the "-T" means Treasure?
The Psvane website doesn't mention "Treasure", they use "Classic", "Art", "Legend", and "Acme" Series naming:

Naming, versions aside, I'm very interested in what you think of your Psvane CV181-TII's; Thank you for sharing.
I really appreciate that summary you linked from back in 2013, from a Psvane employee, it is very helpful.

I read the SE compares competitively to the TII although the listener preferred the latter. Same for the Shuguang CV181-Z. I may look at the SE a little later but first I'll feel out if the TII is something I enjoy. It is nice to confirm from Grant Fidelity the authenticity, I also saw the relabeled Linlai which gave me some pause and I've seen truckloads of weird tennis ball variants which furthered trepidation. I'm unsure what the oldchen refers to but perhaps it's a custom contract similar to the David Shaw variant.I really appreciate that summary you linked from back in 2013, from a Psvane, it is very helpful.
And, thank you to funn chen (Member of the Trade: PSVANE Tube).

The Aliexpress stores like the one I linked advertise matching tubes in pairs, quads, octals, and show equipment capable of doing so. It was nice to get the Psvane 12AU7-S "Collection" Matched pair boxed with the measurement cards showing they were matched. No need for matched tube pairs with the TA-26, only 1 tube needed.
And, I've been wondering about this Globe Tube from PSVANE too, I noticed it has "oldchen" in the name and written on the tube envelope!, funn chen? :

There is also an "oldchen" populated "oldchen" preamplifier, but the title calls it a Laochen?

There are 2 less expensive Psvane labeled versions of this tube, without "oldchen" or the same Grey Silver envelope. One has a Black coating and the other has a "Silver Reflective" coating. I've also seen Psvane 6SN7 Globe tubes, with relabeled Linlai 6SN7 versions and blue envelope versions.
I wonder how the "oldchen" CV-181-SE sounds? And, I wonder if that Globe will fit in the TA-26 recessed socket.
What made me think it might be a honorific naming from someone at Psvane or Shuguang was because there are no "plain" Psvane Globe CV181 variants, SE or otherwise, other than the "oldchen" SE variant and the "oldchen" tube is also labeled "made by Psvane". There are no other "Globe" variants of the CV181-TII, that I've found:
I dunno. That bottom one looks like they just glued a tube base to a Xmas tree ornamentWhat made me think it might be a honorific naming from someone at Psvane or Shuguang was because there are no "plain" Psvane Globe CV181 variants, SE or otherwise, other than the "oldchen" SE variant and the "oldchen" tube is also labeled "made by Psvane".

There are 6SN7 "globe" variants, here is the one with a "shiny" coating:

But, after I saw the "oldchen" equipment - there are more than that preamplifier, I also think that it must be a contract with Psvane and they've secured a cool CV181-TII variant as the "oldchen" CV181-SE, pretty cool for them
Please let us know how they sound, and fit in your amplifier.
Update: I checked on the Psvane company website, and did a search on the CV181-SE, and there was nothing found, so it looks like a contract job and not a Psvane core model:

Looks like you might have a 6SL7 in there. Check that oval plate RCA meatball logo tube…
Not if you get it plugged onto the socket correctly, and that one may be the best tube of the bunch. Devices as shown in the link can fix it so you don't accidentally plug it in wrong one day.
