Linlai E 6sn7 tubes

So I bore the loud hiss of those Linlai's last night just to see if they do sound "good" and I do see how nice they are. Very fleshy.

I tried both my Sachs outputs and both have the same loud hiss. I'm wondering if the cables are influencing this so I might swap out the preamp cables tonight and give it a whirl. I have to put my ear 8 inches from my tweeters to hear noise with all my other tube choices.

I have another set coming from China but coming from the same suppler doesn't make me think the end result will be any better. I bought these on Ebay. I should look at another vendor perhaps? I can't imagine shipping with those nice boxes and foam inserts caused both tubes to be damaged. 

I should send my first pair to someone here to give them a try and see if it is my system. Any volunteers?

I'm in. PM sent

@bugredmachine I agree it is hard to believe both tubes could be damaged in shipping the same way. Also hard to believe cables are going to make a huge difference, since they are working well with all the other tubes.

I have seen reports on noisey old tubes being fixed by cleaning the pins and even resoldering them. If you have to send the tubes back, I wouldn't try resoldering. It might be obvious they were "messed with" and seller could blame that for the malfunction. 

Thanks,

New tubes from the dealer on Ebay and the pins are shiny new. I did not want to muck them up with the High Fidelity contact treatment. I could try the old standby solution, Deoxit.

I'll send these to Dan so he can try them regardless.

@bugredmachine IF one tube can get rattled apart in shipping, the tube sitting next to it in the same box, taking on the same drops, blows, or crushing during handling, can get damaged too. Triple boxing with stuffing will become a cheap fix of the future. One of my sources learned this after two years of multiple DOA sets.  

Or, maybe it has nothing to do with shipping, so (as you are) it sure seems worth trying a second pair and letting someone else try out the first pair for ya and compare notes. Good idea.
