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?

Not if they are still functioning properly; tube life varies considerably and it is quite expensive to replace all when one dies and unnecessary in my experence. Make sure that the bias is properly set for both the new one and the old ones.
