Tube life in preamp. Please help

Hello-

Using an Audio Research SP9 and I've shut it down each time between listening sessions.

I find however it sounds better if I leave it in the standby position.

How much does this lessen the life of the two tubes it contains? They were Amperex and not cheap.

Please advise. Thanks!

don't leave tubes on stand-by if you want to save your equipment and your dwelling. it's dangerous no matter how well tube electronics are designed. if you're not watching your equipment or go to bed you must turn that off.

Well, Wolf, i once re-wired point to point VTL tube amp that started burning in front of my eyes, but I'm glad you're always holding premium cards that you don't have to fold.

Czarivey-You are a bit paranoid, aren't you? Not too many amps will "burn in front of your eyes" unless you mess with them...
Paranoid is just definition and definition maybe just another form of bs. burning amp wasn't bs it was a fact.
Don't know if anyone messed with that, but it all started around just ONE failed power tube.
