Do I need to replace all my tubes at the same time


I'm new to tube amps. One of my tubes just died. Do I need to replace them all at the same time? or just the dead one. Will have tubes with different amount of hours on them in the same amp affect the audio quality?

I think tubes should always be replaced at exactly 3:02 PM
Standard or daylight time?
