Do I need new power tubes?

Do I need new power tubes?
My amp has recently started making a horrible crackly type distortion at even low volumes. It's a 66 bassman. It has lost a lot of volume , and it makes the crackly noise when I turn it off instead of the usual pop. At first I thought the speakers were blown, but they turned out ok. Is this a problem with the tubes? For the past year, I have been running this amp with the volume between 8 and 10 for about an hour a day. Could the tubes be bad already? Thanks. Please email me a copy of any response. I don't have web access from my dorm room, but I can check email there.
