Most Musical 6NS7 tube for a Preamp?

@ptrck887

The Shuguang Dawning Series WE6SN7 PLUS. Bought a pair on line from a Hong Kong dealer.

Can you share this dealer's link, contact information? Thanks

Hi tyray,

I bought them at China Hifi audio, but since then there has been a big shake up at Shuguang.....some sort of family split?  Not sure.  They no longer offer the Dawning Series WE6SN7 PLUS.  I have since moved to a Don Sachs II pre and although Don liked the Plus series in his pre, I did not.  They were ok but not great.  I have been back to running NOS.  Sylvania Bad Boys in the output stage and Marconi's in the buffer.  Don supplied Pasvane Globes and they are quite good.  

Have fun!

Wow! Thank you for your quick response! I almost pulled the trigger on the 'non  Dawning' Series WE6SN7 PLUS tubes on Amazon.

On the 6NS7 tubes, I bought the Don Sach’s Valhalla amp with upgraded Linlai 6NS7 tubes and they sound great. I was able to compare them to the "stock" tubes sent with that amp and they were much better, in my opinion. I haven’t tried the E series of those tubes but I will when these tubes no longer function. There is at least one thread on these tubes. They are larger tubes so you might have to use socket extender(s) to fit them in.

I just pulled the trigger on (2) matched ’poor mans’ Marconi 6SN7’s, the Canada Marconi 6SN7 5692 6SN7GTB Copper Rods 3 Holes code date 1952. Right now I have matched 1940’s (1) Sylvania 6SN7W metal base and (1) Sylvania 6SN7GT metal base in my LTA Microzotl MZ3. I’m also in the works with Andy of Vintage Tube Services to purchase (2) Matched Sylvania 6SN7GT 1952 ’Bad Boys’.

@ptrck887 thank you, thank you, thank you, for taking the time and effort to patiently walk me through the educational process to get the right tube. After comparing the picture of the Canada (Marconi) GE 6SN7 5692 6SN7GTB Copper Rods 3 Holes tube with the Canada Marconi 6SN7 5692 6SN7GTB Copper Rods 3 Holes code date 1952, they were identical. The Canada Marconi’s 6SN7 5692 6SN7GTB tubes are taller than other 6SN7’s and that’s when I knew I had the right tube. It was just the luck of the draw that the Canada Marconi 6SN7 5692 6SN7GTB tube is dated 1952. And another good thing is the (2) Canada Marconi’s only cost me $170 US including tax and shipping with a 30 day return policy.

The Canada Marconi’s were bought out of country so it’s going to take a while for me to get them and burn/run them in, but I will keep everyone posted.
