Leave tube amps always on?

Today I will be watching football with the volume off,and listening to my main system which has a tube preamp. I won’t be leaving the house,so I will keep it powered up even if I go hang with the Mrs. before kick off. 

His reasoning was that it uses considerable more energy to turn on/off on a regular basis.

Do others agree?

Uh, no. Not even other manufacturers. He should have done his math before saying something like that.


Now the amps probably take about an hour or two to sound their best; if this is the criteria (other than just simple warmup which takes 30 seconds) then the answer is still 'no'.

I dont need any more convincing. Mr. Berning’s ZOTL preamp/amp technology is mind blowing performance, like nothing I’ve ever experienced sonically and I don’t want that burn out faster lol.

Being an owner of ARC tube gear, my response is NO!  My gear is probably 80% of the way there after 20 to 30 minutes after start-up.  After an hour, my gear is all the way there.

I echo what another some of the posters said about tube life.  My amp uses KT-150s, which are expensive power tubes that, per ARC, have a service life of 3000 hours.  Too darn expensive to leave my gear running 24/7. 

I am also concerned about energy costs and even safety.

So, ... NO!!!    

I have a pair of Futterman OTL3s, modified from pentode to triode. 

If I’m listening and have to walk away for up to an hour or two, I leave them running. 

Otherwise, I turn them on, wait a half hour, and when I’m done, they go off. 

Reasons:
- fire hazard
- tube wear
- waste of electricity
