There are two reasons to change tubes in an amp. 1) Improve quality of tube and 2)Change the tone of the amp. Different brands of tubes, both new issues or NOS, impart a distinctly different tone. To be sure you get the tube that is best for you, you will have to be able to articulate what it is you want to change.
To do this you will have to listen to your unit for a considerable period of time to learn its sound and know where to take it. So listen and take your time. Come back in 6 months or so and someone will be able to give you pertinent help.
Do so now and you will probably be wasting your money and will go through multiple tube sets before you accidentally find what you like.
