I just found an old Knight KG600B. The latest test data on the scroll
is from65. I need to test a 7868. Any of Yall have the settings for
this tube? Thanks for any help. Allen

It is "almost" the same as a 6GT5, and you may need an adaptor for
your tester. The bias voltage will be lower (if adjustable on your
tester) for the 7868, and there is one pin different on the settings.
Also electrically similar to the 7591.

If you have the adaptor, you may test it as a 6GT5. If not, you may
not be able to test that tube on that tester.

Not much help, I know. My Hickok has both settings _and_ warnings
about the adaptor.

I know it's in the supplemental book for mine... I had a spare copy
but I sold it. Check the data at BAMA:
http://bama.edebris.com/manuals/knight/600tube/ - I think it's in the
addendum I posted there. If it's not there send an email.
