Vacuum Tube - 12AX7 / ECC83, Mullard Reissue

Question:
Would this be a good tube for a Marshall VS8040? It was made in 1994 still has the original tube. Thanks!

Answer:
Ok, yes i understand there are a lot of different opinions out there. I am not quite sure which to select from the comparison chart because the valve state amp is not a full tube amp. I assume it will not make as big of a difference changing out a tube on the valve state. I just want to buy a new tube for it a looking for the best "Marshall" tone i can get. If you recommend a tube for me I will not be disappointed. I really am new to the "tube" world. Thanks
