Hi! I'm new here, so bear with me! Have you ever tried any "Psvane" Treasure Tubes?? Well not treasure but Classic Grade, CV181-T Mark II Tubes. They replace CV181, 6SN7, CV181-Z. I picked one up on amazon for $86.00. Not done burning-in yet but so far this tube kicks some serious ASS!!! Anybody out there know how reputable this company is???

They look sweet as well, the story is the original design team of the Black Treasure left Shu Guang and started their own company... PSVANE. Same tube? (Check out the Sophia) (and those 5692 are $$, this whole group is! )

Lol, I have a few youtube vids in my favorites folder, like to share them once in awhile. I found this from another forum supposedly from a direct Chinese dealer of both tubes..

"Hello!
I am happy see your message.
Psvane and ShuGuang we talk about it now.
Psvane have three series. Price from low to high is:
HIFI,
Mark-II,
Re-edition Classics

ShuGuang have four series.Price from low to high is:
General Series,
Black Treasures,
Sound Of Nature
Re-edition Classics

ShuGuang earlier than Psvane was born.First they are same factory and same technical personnel.
Now Psvane has been out of ShuGuang and It's an independent brand.
You said KT88 and 6SN7.
ShuGuang's General Series KT88-98 have the most stable performance and price is not high.
6SN7 which one is better hard to say.
If Psvane and ShuGuang comparison of the same level is can't say better or bad.
Because every tube and every amp is different.They parameter is different.Personal preference also different.
But high level's material is better than general."

I see some US retailers starting to carry some of these tubes, but at twice the price you can get them shipped free directly from China (usually Hong Kong or Changsha). China Post hands off to USPS but all tubes I've received were very well packaged and arrived without any rattles. The Black Treasure Shuguangs and MK-II PSVanes in 6SN7 configuration are the best I've heard. The Black Treasures have a rather long burn-in time but the PSVanes are delightful right out of the box. Simple 6SN7 solution in the SP-14 is just to put the PSVs in the front holes and the Treasures in the splitter holes, and after about 50 hours you can swap them out". End Qoute.

I'm now curious about the PSVANE, and will probably grab one later on. Nice buy dude!

Got a couple more odd balls in:



The Channel Master is interesting. Really big sounding, aggressive..sort of narrow soundstage.

The Seeburg reminds me of the mystery blackbase RCA. May be the same tube:

I have my line-up for listening this week. Trying to re-evaluate part of my collection. Will take listening notes as I go.

I'm interested in that CKR Kenrad there to the left...

It is a very nice tube. Smooth, decent Bass, works incredibly well with the Chatham JAN CAHG 6AS7G. Perfect for Jazz, Orchestral music. Not quite fast enough, or with enough bass slam for rock or EDM.

Cheers.

New combo this evening in the 336.

RCA Black Plate "Coin Base" with the Tung-sol Coke bottle.

This combo is very treble forward but with no sibilence. "Crisp" is the term I'd use. Anyone with complaints of the HD600-650-6xx being "veiled" should take a look in this direction. Imaging is still good, I'd say a bit more narrow than the GE GTB/JAN combo that has become my favorite. With that crispness comes a little thinness and I'm sort of missing the low end. But I'm going to spend a little time with this combo, especially with the coin base.

Also, got both of these guys in this week.

Unfortunately they both buzz like crazy.

Did you do the fitz mod to your amp? If not you might have to leave the amp on for a few days before the tube will quite down. I just didn't have the time to do it to all the tubes I have so I did the mod. It's a very easy mod to do and will eliminate all buzz from the tubes.

I did not. That's just adding a resistor across the tube socket right?

Yes a resistor or capacitor. Here is the thread showing you where to place them. https://www.head-fi.org/threads/dv-336se-hum-fitz-mod.353079/page-2

Got my Tung Sol 7236 and my hd6xx today. The hd6xx goes so well with the darkvoice. Kinda like my emotiva and argons.

Really liking the Tung-Sol 7236 and silvania combo. I don’t feel the need to buy anymore tube

I had my Tung-Sol 7236 lying around for a few weeks and just trialed them paired with a warm-sounding tube (1954 Sylvania 6SN7GTA). I'm really liking this combo so far. My earlier combo (RCA 6AS7 + 1954 Sylvania 6SN7GTA) was a bit too warm-sounding to my ears at times. Also, I tried a 1951 and 1952 Sylvania 6SN7GT's (tall bottle, 2-hole plates; '51: rectangular micas; '52: round micas) and the Tung-Sol 7236. The '51's had an incessant hum even after three days of burn-in and the '52's were fine. Altogether, the pairing sounded more sterile, more pristine than my preferred combo, closer to my Magni 3 but bigger soundstage, better treble response, and the bass being more taut. In the end, I preferred the warmer tilt of the 7236 + 6SN7GTA pairing.

EDIT: Added Sylvania 6SN7GT + Tung-Sol 7236 impressions

Ok guys.... Thanks a lot for all the Tung Sol 7236 posts,,... I caved.... Just ordered one. I guess if your a serious collector or trying to be one...THIS has to be in your collection. Cant wait to hear this thing.

Hah, I'm just trying to find a pairing that pleases my ears (within budget of course) and then buy a few backups because you never know if prices will increase in the future. I doubt I'll ever cough up the funds to purchase NOS Sylvania '52 (early) 6SN7GT 3-hole "Bad Boys" (the prices and hype for these are unreal), NOS Tung-Sol 5998's and NOS Western Electric 421A's.
