correct way to turn off tube preamp

turn your amp off or on standby first then turn preamp off,visa versa,turn on your preamp first,wait a min. then turn your amp on,,

I got in the habit years ago of turning the level control all the way down, then I power down the amp(s), wait 10-15 seconds before I power down the preamp, then power down the sources. This is for tubed gear. For solid state gear, I leave it powered on.

As my tube pre has no fuses, I was told by the builder to turn the pre on, wait while the tubes warm, and then turn on the SS power amp. Always with the volume on zero. To turn off, first the power amp, then the tube pre. Again, always with the volume on zero. I do turn them off if I am not going to listen to the system for a day or more. If I am going to listen seriously, I let them both warm up for at least 4 hours. Just my opinion.

By leaving your amp on 24/7 do you mean in a stand-by mode when not listening to it? If not then my suggestion is that you should never leave an amplifier on 24/7 (tube or ss) it is dangerous as well as wasteful.

Chuck when not listening I have the amp in standby mode and have the tube pre turned off. I have a Naim CD and flat cap..Naim advised best results leaving it on. The Naim gear is very cool in idle. As a sidebar to all of this, I was always leary of tube gear. After 30 years of buying audio equipment I bought a deHavilland UltraVerve. Its the first tube preamp I've owned so I can't compare it to other tube equipment, but I can say it has made more of an improvement to my system than any other piece of equipment I've ever bought. I was not prepared for how nice a tube pre can match with a SS amp--I can't ever see going back. I hope to now go to a new SS amp (looking at Gamut, Pass .5 or Blue Circle) My monitors-Focus Audio FS688 are 85db, so I want to stay with a SS amp. Thank you again for your responses.
