Good for you! Tubes in this model are: 6F6G, 6Q7G, 6A8G, 5Y4G, and 6K7G. All are fairly common and relatively inexpensive. Additionally, you have the option of using "GT" or metal tubes, which are normally less expensive than the "G" tubes.
I have no idea how many hours you will get out of a tube. Having a set of replacements just in case is a good idea.
