Agreed that they are noisier than solid state but “noisy” is relative. There are lots of tube amps that you hear the second you turn them on. Others are really quiet. Not as quiet as a fully balanced solid state, no question, but they don’t need to be noisy.
Cheap tube amps have an audible hum from the transformers and lots of noise through the speakers. Better amps with better transformers are much quieter.
