    Hi

    Just wondering what the figures for tests on tubes represent, and what are good figures?

    Below I have two examples of testing figures for matched pair tubes. Which are the better performing tubes, and why?

    1. Tested : 13.5/11.8-12.4/11.2 7LC delta 0C1

    13.1/11.4-12.5/11.4 7LG delta OC1

    2. Tested : 9.8/9.8-9.5/9.5 7xx delta9A2

    9.2/8.8-9.8/9.3 7xx deltaF2

    THANKS!
