I find it hard to believe that all six would be gassy.
It is possible that it is an artifact of the TV-7 test conditions.
I recently had two 45 Globes that showed high grid emission (usually a sign of gas) on my Amplitrex AT-1000. When I tested the same tubes on my Westmore 501 and Hickok 752A, there was virtually no gas/grid emission.
By coincidence, I am supposed to receive a freshly refurbed (by Dan Nelson) TV-7D early next week (with digital meter :).
I have some 6N23P (rocket logo) laying around.
Once I have a chance to set up the TV-7D, I will try to test a few and see what happens.

Thanks Baileyler, please do.
Got my TV-7 back yesterday from Dan Nelson.
Ran a couple of Amperex USA 6922 and 6N23P, and none had any noticeable gas reading.
There was a minor reading increase on all tubes on the digital meter, but it would probably not be noticeable on the analog meter.
Do you have a second tester you can run the tubes on?
If not, you should get at least one other decent one. :)
(I have many different ones)
Thanks for the update!
