6sn7 tube question

I find it much more enjoyable to purchase low noise current production 6SN7 vs "by at your own risk" NOS exotic. Almost every exotic NOS 6SN7 that I have purchased, most from very reputable sellers, was either noisy or had a very short lived life.

Just a side note; It could be a short lived sonic experience if you don't watch the maximum plate voltages. NOS 6SN7's can run from 275 VDC (for a 5692), up to 450 VDC for a 6SN7GTB series. You should contact your amp manufacturer before dropping serious $$$$ on NOS to see what the electrical environment is for this valve. Also, some power amps use 6SN7's in both the input and driver section and again you may have two different values to deal with.6SN7's are alot of fun, especially in flavoring preamps!Good Luck!

Not sure if they make 6sn7's, but the Euro Audio Team (EAT) has gotten some great reviews on their new tubes. Worth a look see.
