Anyone try modern 6sn7 Shuguang WE type vs NOS RCA,Ken Rad


I just bought a KT-88 amp that uses 6sn7’s and the matching preamp uses the 6sn7 tube also. It came with kt88 Shuguang WE plus and all 6sn7’s in the amp and preamp both came with the same Shuguang WE plus.
 

I have a huge stash of old 6sn7’s Ken Rads vt231, gray glass rca, Sylvania vt231 and many others. I am going to pull them out this week and see what these new production tubes can do.

 

I’ve never used new production signal tubes. To be honest the Shuguang sound pretty good but have never compared them to anything. 

 

What are your views on these new tubes are they even close or as good or even better? Are they cheap and will go up in smoke, thanks for any insight.

@markusthenaimnut  I remember reading about Shuguang closing down a factory. But it seems they are up and running with new production tubes.

From AA 2019...

@paulcreed  sorry, I was without internet yesterday. This sounds interesting, I'll PM you when I get home, 

Can anybody recommend quality octal adapters? The last set I bought was not an exact fit for an Atma-sphere amp. The dealer said there is some variation between pin spacing on adapters.

@markusthenaimnut , 

You've got all the correct information. Apparently the Shuguang factory is gone and the company has ceased production.

Another page turned and, apparently, the top engineers who had been involved in the Psvane venture left to form Linlai.

Apparently the Linlai production tubes are well regarded.

This advert confirms there are no reliable sources for Shuguang WE6SN7's...

There are many fakes of these in the marketplace and Shuguang Factory is being rebuilt due to fire so legitimate new ones are not available.

I run the Shuguang WE6CA7 Plus in a Mystere PA11 and really like the tubes performance.  Wish I could get a quad of the 6SN7, but….  They have a pure, un colored sound compared to EL34.  Very nice tubes.
