In general yes...

The standard disclaimer: best to follow the recommendations of your equipment manufacturer; risk of damage or voiding the warranty.

You can substitute 12AU7 for 12AX7 because the AU is a lower gain tube. I've actually done the above. I think the AT is in between the AU and the AX. There are other tubes that could sub too. DO a search on something like '12AU7 AND 12AX7' and you should be able to find many old posts about subbing tubes.
