What is a NOS 6SN7 tube with these tube testers??


I am very familiar with the TV-7 and Hickok tube testers and what level for a 6SN7 tube is a like-new tube and what is passing.

What is the like-new and pass ratings for a 6SN7 tube using a B&K, Sencore, Eico, Jackson, or any other brand people have experience with?

Any website with this information would also be great!!

A lot of tube ads on the web quote the test results, but without a frame of reference, they are not very useful.

Sugarbrie, you can at least specify the order of results at Audio Asylum. The function is near the bottom of the search specification area.
