I recently bought a lot of tube to work on some amps and have backups. but I am now confused on matched sets and if the testing translates to a "sound" or outcome.
Example:
All EL34 for this and apex tested...
I have a set of EH that test 42 current and 6900
Mullard 28 current and 5840
Tung Sol 23 current and 6460
Questions:
Also, how does mesa do this on 6l6 and never needing biased? Are all of their 6l6 branded tubes the same range and thats all they sell? If so, when you put in a new set of 6l6, non mesa, what do you need to be aware of?

Questions:
- will different brands test differently? Is an EH 42 the same as a Mullared 28?
- Will a 42 current sound differently than a 23?
- Does current matter?
- does transcond matter?
- It seems that the 42 is high but is it really and is there more to this I should be looking at?
- These are going in a 84 JCM 800, is one better than the other based on numbers? Will one set break up earlier than others?
