is it ok to leave a tube amp on without speakers connected


I'm blessed to have two amps but one set of speakers in my listing room - all tubes.  Instead of cutting off one to listen to the other, I would like to listen to the other without powering off the one i'm not listening to.  

Question:  Can tube amps be powered on without speakers connected for hours at a time?

NO. NO NO NO NO NO. Had a pari of VTLs without my WATTS attached. Scared the color off me (I'm Hershey Brown colored).
