In Reply to: How do you know a tube (E88CC) is used or true NOS ? posted by akltam on October 31, 2017 at 08:08:10:
Some times tubes were "burned in", then measured and if they met specs packaged. NOS or used then? If a tube checks as if it is new, that is what I look for. Some times mil tubes were "burned in" and checked for performance on a man schedule...NOS or used?
Never assume anything I post is accurate.
