I test all tubes on my emission tester, and toss any that have shorts and do not test high in "the green". After that I plug them in my amp, and run them for at least 10 hours before retesting, to ensure no early reliably issues. All the listed tubes were tested and seasoned with this method, but I am not able to plot or record electrical data. Let me know if you have other questions.
