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!

Too right Brauser, all that happened to me as well !
I have a theory, most tube freaks never heard ,say, a quad of Sylvania 6550's from the 1950's in full cry, the junk output tubes available today make tubes a non-starter for me today.
