6SN7 Tube Addicts - Page 8

You can't get wrong with a pair of Sylvania 6SN7GTB's.
It's all about trying out and see what you like.
With the tubes Skylab mentioned in his top 5 you will be near perfection, can't get much better than that.
If you are just starting your 6SN7 adventure buy some cheap ones for starters and take it from there.
Be warned it can get very addictive!

I have the same pair of GE that came with my WA5LE, just tried them out. Ouch way to harsh coming from my Shuguang Treasure CV181-Z / 6SN7GT matched pair, Grade A.
I only used the GE for a short time at a lower volume than my CV181-Z and my ears still hurt.
From what I heard of the GEs, the CV181-Z did everything better with no ear fatigue what so ever even at a much higher volume level.
imo the Treasure is a much better tube, and maybe that's why Grant is always out of stock on these tubes.

I am now looking at the TUNG-SOL 6SN7 MATCHED ROUND PLATE CTL 6SN7GT NOS late forties. Just to make sure the Treasure are as good as there is.

I have a pair of Shuguang Treasure CV181-Z as well, and they are indeed very nice tubes. I do prefer real Mullard CV181's, but these have become very, very expensive. I thought it was a reach when I was buying them NOS for $150 each - now they seem to go for $250+ each. That makes the Shugie a more affordable option, especially as they have come down in price.

Interesting, I didn't think that the North American Shuguang Treasure premium grade 'A' had come down in price. Yes I know you can get lesser grade Shugie from China sellers or even from Grant Audio. But to me those lesser grade Shugie are like NOS, cross your fingers and hope for the best.

Maybe you're right - I didn't look on the ads I have seen for the grade. I got mine "Grade A" from Grant Audio shortly after they because available - and they were pricey.

I have a line on a matched pair of Tung-Sol 6SN7GT oval mica [1942-46] NOS.

What do you think of these in my SET 300B WA5LE? My WA5 is the latest version of the WA5 and it has the parts upgrade.

I must say I do love the Shuguang Treasure CV181-Z in my system. However I only have about 390 hours on it.

Yes, and this is how they are described by the seller.
"Hi the tubes are NOS I have not taken photos of the boxes but are available.According to the box dates they are made from 1942-1944.No cracks off-course.I hope that you understand that we are talking about new old stock tubes.My brother an ex mil technician had purchased these tubes in the late sixties and stored them in our basement.Started selling them only 3 years ago on ebay now its our last pieces.
Tubes are tested with the Centrad tube tester and from 1-10 they are easily take a 10!!!"

I also buy my tubes from John and they are first class for sure.
Excellent choice.

I think there are two Tung-Sol 6SN7GT "Round Plate" versions. One with the round mica which were manufactured till 1942 and the other with the oval mica which were manufactured from 1942 - 1946.

I have a Tung-Sol 6SN7GT Round Mica tube, and in my system its the best sounding tube. Close second are Brimar 13D2 and Brimar 6SN7GTY.

I think that the round mica were made untill 1942 and then after 1945 or 1946.

Do you rate this better than the 6SN7GTY?

Slideshow for 6SN7 VT-231 CV1988 5692 [b]

Some nice pictures of the diffrent 6SN7 tubes..(I was looking for a picture of the Brimar 6SN7 GTY.

Is this a good price? http://www.audiogon.com/cgi-bin/cls....sn7gty-CV-1988

I guess $100.00 each is a little high...http://cgi.ebay.com/ws/eBayISAPI.dll...m=120552764207
$39.53 for a pair.

That audiogon listing and ebay auction are for different tubes. The Brimar 6SN7GT is not the same as the CV1988/6SN7GTY. The latter is brown bass, black glass.

skylab, I agree.
markmaxx $100 for one 6SN7GTY I think is a fair price for a lot less than that you may not be getting the real GTY.
