I have tested on my B&K 747 these tubes and always got different values as 85 / 60 . Is this a good value or how should test a good NOS.
Thank you for answers.

The 6EM7 is a dissimilar triode, the two triode sections are not identical. It SHOULD show different results. The B&K will do a good job of testing the tube, just set it up and test away. You'll note the test setups are differrent.
Thank you, I had no problems with testing the 6EM7. I would like to knew if the value I got (85/60) means the tube is good or waste.
Your tester/manual should tell you what the minimum and new values are to compare your test results to. If the mesurements per triode beat the minimums for each section, then the tube is good.
