How long does it take your tube amp to warm up?


My tube amplifier has about 12 tubes and takes a couple hours for it to open up and sound really good and comfortable to listen to. Always wondered why it takes so long for a tube amplifier to warm up and what’s happening during this phase.

If I left it on for six or seven hours would it sound even better? I normally don’t leave it on for more than four or five hours.

Please let's not keep the equipment on all the time. There is a need to be somewhat concerned about environmental issues.

 

Is the benefit from an extended warm-up more so due to tubes warming up or the transformers?

Seems the tubes would be getting warm pretty quickly. Since the transformers are larger maybe they take longer.

My amplifier which has around 14 tubes is much better to listen to after an hour. A bit constrained during the first hour.
