My Don Sachs preamp uses four 6sn7s. Don supplies them with Shuguang Treasure or WE6sn7plus tubes. He swears by them. On his website he describes the many 'holy grail' 6sn7s that he owns and then goes on to explain that the Shuguangs walk away from them all. That's quite a statement. In my experience, they are excellent tubes. I still have the original tubes supplied with my preamp and have gone through more than 2000 hours on them an counting with not a hitch.
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.
