try tube asylum....or tube diy asylum. Might also call the Atmasphere folks I think they use these tubes.
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.

Ask Kara Chafee. She repairs hickock testers and with an email address of [email protected] should be able to give a definitive answer! That said, I think its more important to have the two triode sections in an individual tube to be closely matched than the absolute values. -Stephen C. |
