Television through tube preamp?

I'll be receiving a tube preamp in the next few days. Since my apartment only has one room (it's a studio), my TV is in the same room as my audio setup. I was wondering, is it okay to watch TV with the sound going through a stereo tube preamp (and SS amp)? I assume there is no problem with this, outside of the wear it puts on the tubes. If possible, I'd rather not have both a receiver and a stereo amp/preamp in my cabinet (due to space constraints), given that I don't care about HT.

Any thoughts?
