Linlai E 6sn7 tubes

Don told me to let the tubes run for 20 hours. So far in 8 hours, no change. One tube is 10x louder than the other. I can hear it outside the room. Swapped the cables left to right and the higher noise tracks the tube. The lower noise one is still ridiculous. I'm not sure how you guys are putting up with this. I have to get to 8 inches of my tweeters to hear small hiss from the Shunguangs.

Don says the preamp is fine and he does get an occasional bad one but his volume is high and he is okay with that. Only one source for these I understand so are the sellers actually listening to the tubes before shipping out?

@bugredmachine, please excuse my lack of technical knowledge,I concede that most here forgot more than I know. That being said,let me throw something crazy out there. Is it possible that this tube in your room is acting like some sort of antenna? Is it possibly picking up some radio or electronic interference?  

Has anyone experience the lack of low end in the tubes with your set up's? 

From what I observed,these tubes took at least 50 hours to start to open up. These were kind of impact free on all levels at first. After having well over 200 hours at this point,these are very full frequency tubes in my system,  

@rocray , the reason I'm asking is because of how the tubes make my Orthofon sing. I ordered a SME spacer for my Hana ML. which I will alternate on my TT. I WILL order 2 set's soon, just would have to get the info from @aldnorab for the socket board.
