New to tubes have questions


Hello All,
I am going to try a tube amp and I have a few questions I need help on. I have read the manual but I need to be clear
1) is it bad to play the amps without them warming up? will this hurt the amp?
2)does the amp have to be warmed up to check the bias?
3)what is the biggest don't with tube amps?
Please help me understand these questions
Thanks

The biggest "don't" is never power on a tube amp unless it is connected to a speaker.
