The manual for my Mesa TC-50 says "...at least 30 seconds, preferably longer."
At home at low power, I probably let it warm up for a couple of minutes. On a gig, I probably let it go for 5 or so then take it up to gig volume. Sometimes, at a gig, I think I perceive a difference on how it sounds after 30 minutes or so of playing but that's just as likely to be my perception as it is to be reality.
So there might or might not be something to the idea that you get optimum results after longer warmup periods, but the notion that you have to let a tube amp warm up for long periods before playing it is nonsense.
