Yes, seems like it is normal.
I do not understand the "gas" situation, I also suspect it could be normal, as it is uniform across the 7 tubes tested, present on the 2nd triode.
And another thing that confused me is, all tubes are borderline good/replace for 12AX7 and high end replace for AT7.
Probably normal. The amp is 7 years old and the tubes are all Chinese. With heavy usage it is likely the case.
I have little to no experience with the miniature tubes, so have little idea as to their behaviour.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
