Four Hour Tube Amp Warm-Up

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.

That seems rather long---that wouldn't cut it for me since I rarely listen to my music for 4 hours straight. I don't have tubes but my Sugden A21 sounds pretty sweet after about 15-20 mins.

Maybe it’s your tubes. My tube amps, both vintage McIntosh, get with it pretty quick, like less than 20 min.
