Did you know if Raytheon Blackplate wit the ladder style plates, are sonically the same betwee the variant 6SN7GTA and 6SN7GTB ? And is there some people who prefer psvane CV-181-TII or Shuguang Treasure CV-181-Z against good old NOS (TS, Sylvania, and so ) ?- gug42

Guys does anyone out there in Head-Fi land know of any UK, or Europe based sellers of the Shuguang Treasures CV-181-Z ?, I have found sellers for the Psvane CV-181-TMKII, but not the shuggies, all that I have found are either based in Hong Kong or China. Can anyone recommend a seller?.- Scutey

...you really like the CV-181 TIIs. Also, it's interesting to see which specific variant of the Shuguang "WE"6SN7 you are comparing the Psvane CV-181-TIIs to. I'm really most curious, though, about how the CV 181 TIIs compare with those super-tall WE6SN7s with the exceptionally tall bottle and...- MarkusTubesNow

CV181s are all the same electrical specifications. Real CV181s are .96 heater current draw or they are either defective or not a CV181. Now where it gets confusing is with the folks at PSvane and Shu-guang -- they went and threw a monkey-wrench into the works by marketing a line of "CV181"...- Ripper2860

Shu-yuang also states their 'Treasure Series are CV-181, which is incorrect. CV181s have a much higher heater current requirement than 6SN7 and true CV181s would damage many 6SN7-based amps. I don't know why they do that, it just confuses folks to the point where Grant Fidelity even has to...- Ripper2860

your right, the GTA and GTB differ from brand to brand, I found similarities in the Sylvania and GE GTA/GTBs, it may be that in general GTBs are brighter and for a thicker warmer tube a Brighter variant may be ideal! You'll really have to experiment, or wait for some one whose collecting...- Makiah S

Helpful to know, thanks @Ripper2860 . I think my Feliks-Audio Elise can't exceed ~ 6.5A for all tubes combined. Does the heater current draw also vary by brand and specific type of CV181? For example, it appears the PSVane CV 181Tdraws 0.6 if I am reading the specifications correctly.- LoryWiv

Picked up a pair of Psvane CV 181 TMK2 for my Feliks Elise a couple weeks ago and I have to say I'm quite impressed with them. Sound wise I would say they are neutral with a hint of mid range warmth, transparent, well extended highs, detailed wide soundstage with very good depth and separation...- Scutey

I use, and like, both the Psvane T2 CV-181 (really a 6SN7) and the TJ 6SN7 (identical tube to the Sophia 6SN7). Out of 6 T2s I have had one blow in the first 50 hours. Other than that, all good. The Psvanes need a full 300 burn in to get to their best. The TJ/Sophia appears to not...- TonyNewman

...have a nice collection of old stock tubes, but would not hesitate to use new production tubes if the sound was right! I've tried the psvane cv-181 treasure and psvane uk-6sn7, they don't come close to nice old stock tubes unfortunately. I'm also interested in those we6SN7/we6SL7's...- SonicTrance

Thanks rosgr63. I am considering the Psvane CV-181 to be a 6SN7 tube. I am still interested in it based on the history and seemingly good impressions of the Treasure tube it is related to. Do you have a general impression on the tube? The premium ones are pretty steep at $250 a pair, but...- Sid-Fi

I've not heard the Raytheon Variants, but the 6SN7 GTA GE and Sylvania's are audibly better than the B variants Also I forgot to mention! I Compared a number of the Sylvania 6sn7s Going in the tube direction, I got my self 3 Sylvania 6sn7s, a 6sn7 GTA Chrome Dome, a run of the mill 6sn7 GT...- Makiah S
