Linlai E 6sn7 tubes

@danmar123 . Had to stagger mine. Distance between front & back row is less than side to side. So I have left front and right rear on two socket savers each. That barely clears on my linestage. On another forum a man has offered to make custom adapters. They would be a socket and plug with space in between to "extend" the tube sockets further apart. There is plenty of real estate to spread tubes out on top of the linestage. Won’t pursue that until I decide if the Quad Linlai are my favorite setup.

Thanks,

@bugredmachine what a bummer. I'd consider calling Don Sachs for guidance. The Linlai are so big that even staggered with 1 socket saver on left front and right rear the tubes were touching. Didn't notice this at first. The tubes weren't fitting completely flush in the socket. Have to admit the Don Sachs linestage looks impressive with stacked double socket savers and such big tubes. 🙂

Good luck,

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?
