Rob, can I come and dust your closet please?
I'll be ever so careful!

My tube types are very limited I am afraid.
 
Here's my new teaser:

I have a Darkvoice 336SE with a 6SN7 preamp tube. Does anybody know if the CV181 or CV181-Z would work as a replacement, since the two are electrically similar?
 
I'm also trying to get a hold of some Ken-Rad 6SN7 tubes to sub in and see how they sound. For now, I am using a Sylvania, and it performs beautifully. I'm just looking to see if I can try other tubes and get something I like more.

The CV181/ECC32 is not equivalent to the 6SN7.
They draw more current and could damage your transformer.
 
What is your output tube?

Right.
Which 6AS7G/6080 are you using?
 
If you use a RCA 6AS7G and you like a relaxed presentation I would recommend the RCA 6SN7 Grey Glass.

Oh, right. It is a Svetlana 6H13C tube right now (the one that came with it when I got it). I have also been looking for NOS options there. I just got the amp recently, so I am still getting acquainted with all of the solid combinations that others have reported.
 
I've recently ordered a CBS Hytron 6SN7GTB and a Ken Rad 6SN7GT, so I am waiting for those to come in. I also ordered a GE Five star 6080 and a Sylvania 6AS7G. I'm keeping my eyes out for RCA tubes at a decent price.

I've got an extra RCA 6080 that would love to trade for something else :)

This link would seem to indicate that the CV181-Z (the shuguang treasure tube) would be a safe replacement for a 6SN7 even if your standard CV181 is not. I'd like to try it out, but some confirmation from someone who's tried it before would be appreciated.

The real thing is not, Chinese just like to use the numberings and fancy names to sell it better, their way of making and selling things are silly and only for their own profit. What are their knowledge? What have they developed? Their tubes were and are  based on somebody else design / find, what ever its Russian, West/East European or American, period.

The Shuguang CV-181Z is indeed equivalent to the 6SN7.  It is NOT a real CV-181, it is just a 6SN7 in the CV-181 shape.  And I thought is was only just okay sounding, and not worth the asking price, myself.
