Linlai E 6sn7 tubes
@lowrider57  wonder why Linlai isn't interested in small signal tubes? Harder to make? Less profitable? Also amazed tubes change so much during break in. Glass, vacuum, and some metal guts don't seem very susceptible to break in.  My 2nd set of L...

@bugredmachine  that is a nice reduction in hiss. What rectifier were you using and what is the replacement? I haven't tried comparing rectifiers for noise. Great idea. Looking forward to your thoughts on the new caps. Thanks, aldnorab  
Linlai E 6sn7 tubes
@rocray well they sound different than the RCA and Ken-Rad. Replacing the RCA with these brings the lower midrange and midrange forward ( a good thing for my speakers). The high frequencies are rolled off and dark. There is no air and very little ... 
Linlai E 6sn7 tubes
Just ordered 2 more Linlai E 6sn7 for the Don Sachs preamp. Interested to hear it with all Linlai tubes. I've got 25 hours of playtime on the 1st two. Thanks, aldnorab

@bugredmachine my Model 2 also has some noise at 15" away from the drivers. I have the dual gain control model and the hiss volume doesn't change with setting. Think they work on the input instead of the output.  Just ordered 2 more Linlai E6sn7 ...

I should have said RCA/Ken-Rad tubes above^.  Sorry, aldnorab  
Don Sachs Owners Thread
Just received the 2 Linlai E 6sn7 tubes ordered last month. I'll try them in both circuit locations. If they beat out my GE/Ken-Rad, I will order 2 more. These are huge tubes. Newer D Sachs have wider spacing. They will not fit in my older wood t... 
Linlai E 6sn7 tubes
My 2 matched Linlai E 6sn7 tubes arrived today. The Don Sachs Model 2 takes 4. I'll evaluate these in both circuit locations to see how they do. If prefer them to my current GE/Ken-Rad setup I'll order 2 more. I have the older D Sachs with wood t... 
Supratek Owners Thread
Thanks for the info @sc2 . I saw a 3rd party upgrade umbilical cord that was about half that length. It would be very difficult to fit into my rack. The stock Supratek makes it much easier. Thanks, aldnorab  
Linlai E 6sn7 tubes
Does anyone make a horizontal off set 6sn7 to 6sn7 adapter? It would allow spacing tubes further apart on open top preamps. If not, it looks like a fairly simple DIY project. Thanks, aldnorab

@rocray wow, they are big. They look like power tubes. Can't wait for mine to arrive.  Thanks for providing the photo, aldnorab

As good as the Model 2 sounds, I've been missing sweetness and delicacy in the high frequencies. Sound leans towards early CD digital sound, no give and little decay. Not quite effortless. I've had other tube equipment, but used the new tubes the...

Good idea @skypop . Wonder how long the umbilical cord is? Wouldn't want my linestage 2 ft. off the ground.  Thanks, aldnorab  
Don Sachs Owners Thread
@firstgrowth good to hear. It is always nice when upgrades move the sound in the direction desired. What 6by5 rectifier tube did Don send with the update?  Weiss makes great DACs. What were you using before? Please keep posting updates. Thanks f... 
Looking for warm tube preamp (should pair well with Pass power amp), budget $6000
You might also consider a Supratek preamp.  Thanks, aldnorab
