I used to complain about my Primaluna's needing 2 hours to warm up and really sound glorious. However, I now realize that neither the amps nor the Sophia Electric blue "coke bottle" EL-34's were actually broken in. The Sophia's have a 5,000 hour rated life, so breaking them in takes a long time, and I listen to only 2 or 3 CD's per night. The break-in is loooong. Now that everything is settled, the amps are good to go right out of the gates after 15 minutes. They still gain a more awesome midrange after an hour of playing though.
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.
