TA-15 tube swapping results?

[Bill11]

Hi!

I am going to try different EL84's and 12AX7's in my TA15 and was wondering if any of you have done the same and if so, could share your results.

I also saw the new JJ EL844 at Eurotubes the other day and it looks interesting:

How did the EL-844s work out for you? I've got some on order for my Express.
