In Reply to: What is the break in time for an output tube? posted by airtime on October 30, 2014 at 06:21:29:
I maintain that much/most of "break-in" is the listener adjusting to the tone of the new tube. Especially if the old tube was tonally different than the new tube it can take a while to become accustomed to them.
Yes, there is some change in tube performance, but it depends on the tube, on the circuit it is used in, etc. I find that by about 25 hours or so the tube is sounding pretty much how it's going to sound for the rest of its service life.
There's no special procedures to follow - just plug thew tube in, enjoy the music, and you may hear some changes in the tone.
DO check the bias if you have adjustable bias though - at 25 hours or so I've checked it a couple times if it's me, just to be safe.
