Four Hour Tube Amp Warm-Up

My tube amps seem to warm up pretty quickly...10 to 20 minutes maybe? My Pass XA-25 takes about 45 minutes although it sounds damn good immediately upon start-up.

PL Dialogue HP Integrated here. Sublime within 15 minutes of power-up. 4 hours? Sounds like your confirmation bias needs adjustment!

4 hours -- wow. So, tube life is, in effect, one quarter of their expected life for good listening? That will sound like an argument for solid state to many.

I agree with @designsfx for ARC stuff.  A half hour definitely benefits it, but I live in SO FL where it is warm most of the time--NOT THIS WEEK!

As far as hours and hours, I don't really notice much difference after a couple of albums.

Cheers!

My Elekit 300B sounds better than most of the other integrated amps on earth after 20 minutes.  But after 4 hours they’re magic.

Had a pair of Gryphon SS Class A monoblocks that peaked at 12 hours even though I kept them in standby all the time.

Go figure.
