Four Hour Tube Amp Warm-Up


My Primaluna Tube amps require a 4 hour warm-up in order to enter the Glory Zone. My previous Muzishare X7 tube amp was the same. Just wondering if this holds with the experience of other tube ampers.

When I bought my Pass Labs XP17 phonostage I called Pass and asked if it would be OK to leave it on 24/7.  I was told that it was designed to be left on all the time and that is why the only off/on switch is located on the back of the component. 

From the Pass XA25 owner manual...

Leave it on or turn it off: The product is designed to be left on all the time. The exception to this might be a case where the unit will not be used for an extended time - in that case it can be turn off. The main power switch is located next to the AC power cord. (THIS REFERS TO THE REAR MAIN POWER SWITCH)

You are now ready to play music. Turn the level at the source or preamp to a low level. Press the power switch on the front panel of the XA25, the blue LED above the power switch will light. Turn the volume up to your preferred listening level. Sit back and enjoy! The XA25 takes approximately an hour to fully warm up and sounds better as it does. Pushing the power button on the front panel of the XA25 a second time turns it off and extinguishes the blue LED. (THIS REFERS TO THE FRONT PANEL POWER ON PUSH BUTTON)

@bigtwin Heed Audio, Simaudio, Pass Labs, SPL, AVA, just to name a few.

@jerryg123 Thanks.  I stand corrected.  My manufacturers, Hegel, Esoteric, Triode Audio Japan, PrimaLuna, all recomend turning equipment off when not in use.  Oh well, whatever works for you is all that counts.  Merry Christmas.  

@bigtwin I cannot think of a single Tube Amplifier manufacturer that would say leave it powered on. Nor a Hybrid tube SS manufacturer.
