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.

Turntable grease bearing takes 20 minutes to "warm up." By the time that’s done, all tube amps (RIAA/preamp/monoblocs) are ready to go. While things are technically available after 2 minutes, sound opens up and has more musical coherence after 20 minutes, and gets better by the hour. After 3-4 hours, system sounds best.
