Hi all!
My tube-tester is kind of worthless for me without some essential tubedata...
I got EL84, but for example 12AT7, 12AX7, 12AU7, 6DJ8, EL34, 6550 and a lot others seems to be missing.. *crying*

Is there anybody out there, in possession of such data, and willing to share?

Is there any good method to make your own data from datasheets? any link to some tutorial?
