Apparently you can blow tubes by playing? Too many notes? Too many effects? Too many beers?
It ain't gonna happen. I've had too many tubes blown out of my amps by sitters-in who try blasting everything including the kitchen sink through it, and what I see of people in my town they do things to their own instruments that they wouldn't do to their worst enemies or their mothers-in-law. (Or did I just repeat myself.) I take care of my guitars and my amp. I'm not going to have them ruined. Want to sit in? Bring your own guitar and amp, and I'll be happy to have you sit in.
