Linlai E 6sn7 tubes


I just placed an order for a pair of these for my Aric Audio Motherlode II.  I’ve been chatting with a fellow that runs the E 6sn7 in his Don Sachs pre. He loves them, He says they make his NOS tubes sound thin and lifeless.  
    It will be a couple weeks until I receive them,and I was curious if anyone out in Agon land has tried these,and what are your impressions?   
Thanks in advance,

I cleaned all the tube pins with Deoxit and no change in hiss.

Then I changed out the Stealth's for Gabriel Gold's and no change.

After that I put my Shunguangs back in with the Indra's and all was quiet and enjoyable again.

Tomorrow I'll send them to Dan to see if they continue to hiss.

@bugredmachine a buddy of mine has a preamp that reacts in an odd way to gain of different tubes, so it will be interesting for @danmar123 to test for you. Dan, what preamp do you have, same or different than what bugred has?

Sorry cleaning didn't work @bugredmachine .  Will be interesting to see what @danmar123 finds. Wonder what can go wrong in a tube to make it so noisey? 

Thanks,
