6SN7 Tube Addicts - Page 274

post #4096 of 4253

I got a Darkvoice 336SE from a forum member a few weeks ago, and the previous owner was nice enough to include a brown-base Sylvania 6SN7 (JAN-CHS-6SN7WGT) and some type of 6AS7 with a metal base/straight bottle.  Since then I've tried a variety of low-buck 6SN7s, and I have to admit that I keep going back to the Sylvania.  Most were either really flat sounding (GE, Motorola), or actually had a strong hum in one or the other channel (Tung-Sol mouse ear, RCA). 

 

Today I got in a pair of 6SN7s labeled Hytron and CBS, and I'm listening to the Hytron now.  Quite a warm sound, a little muted in the upper registers, but very natural voices (I watch a lot of movies and prefer headphones in the evenings).  Very pleased with this one, but I think the Sylvania is still clearer overall.

 

Still on the lookout for interesting tubes, and have a couple of TS Tall Boy styles on the way, plus a Svetlana power tube.  I also ran across one I hadn't heard of; the Shuguang CV1988.  Is this worth trying, or skip for something better like Brimar, Mullard, or...?

6SN7 tubes worth trying (in my opinion):

 

Sophia 6SN7 (my favorite tube currently)

Ken-Rad VT-231 "black top"

Sylvania VT-231 "bad boy"

Hytron 6SN7

 

Right now I have a Ken Rad black top driving 2 matched Sophias on the outputs of my MPX3. So far it's the best combo I've heard yet, although the Sylvania VT-231s on the outputs come as a close second.

I can't comment on the Shuguang, but I can suggest that the following threads might help you decide which of the 6SN7's you might want to try next:

 

6SN7 Reference thread

 

 http://www.head-fi.org/t/117677/the-reference-6sn7-thread

 

6SN7 Identification thread

 

http://www.head-fi.org/t/209782/the-6sn7-identification-guide

 

And I would also suggest that you take some time and try to skim through the 274 pages of this thread. Yes, 274 pages is a bit much, but there is a lot of good information to be found.

 

Cheers

Has anybody tried the Psvane CV181-TII aka 6SN7? How do they sound?

I would say they are the best of new production tubes. They are up there as one of my favourites.

How would you rate them against :

  • TSBGRP 6SN7
  • Mullard CV 181

 

Thanks.

Quick swap test....

vs my GE 6SN7 ( 1953 Ken Rad?), this Psvane projects a more SPACIOUS, TALLER, DEEPER layered soundstage...and i think it goes lower, cos i felt my DT770/600ohm drivers reverberating more often thru my testplaylist. ( yes right this moment..HansZimmerGladiatorsBattle :P )

 

( done many prior swaps with my other nondescript 6sn7s , same wow effect each time :P) 

 

ps:  there was a low buzz when new, but after about 50hours of burning in...its gone.

^^^ this tubes require 150 hours for proper burn-in so you not even half way there ..just my 2c

post #4104 of 4253

i should have chalked up those hours since last year...cos it refused to give up that slot..but i yank it out now n then :P

post #4105 of 4253

this tubes look great ..I'm thinking about getting Shuguang Treasure CV181-Z ,this tube is physically smaller then Psvane CV181 so I'm little worry about the soundstage

I don't own Mullard CV181's so can't comment. Compared to TSBGRP? In my set up the Tung Sol is king... I quite often have the curiosity to roll to see if anything betters them but I always go back. Like I said earlier though, in new production tubes, I believe they are the best I have.

I don't like the GE 6SN7's, average sounding.

 

The Mullard ECC32/CV181 are worth a try provided your transformer can handle the extra current.

 

The Chinese CV181 have the same specs as the 6SN7 so no problems using them.

Does anyone have a set of Va/Ia curves for the ECC34? I want to determine how much current to feed them to achieve a 75V operating point with a -1.5V bias.

How's this?

You are truly a legend! Not highly resolved, but enough to get into the ballpark. I couldn't find anything!
