Tube amp warm up

How does it sound to you after 5,10,30, or 60 minutes?

I always wait at least 15 minutes.

I really haven't found any difference to reach optimum sound with SS or tube. 45-60 minutes generally.

I've found tube amps easier to listen to though, as they do warm up to optimum performance.

All of the tube amps I've owned needed about 15 minutes to sound good. Is it getting better after that period? Perhaps, but I don't kill myself trying to notice any difference -- I just know it sounds good after 10-15 minutes. Solid state stuff takes a whole lot more time to warm up. I've fooled around with gear that sounds really disappointing until its been on for many hours if it has been off for some length of time. That is usually not a problem because the solid state stuff can be left on continuously.

Hey, I've got a question! I bought a 2 year old tube amp that hadn't been used for almost three months. It took a number of hours to sound it's best but now sounds superb after 10-15 min of being turned on. Wonder what the technical reasons are for it not sounding its best after being 'on the shelf' for 3 months?
