Interesting subject. I am running Audio Note Conquests 300b's with TJ Solid Mesh Golds.I switch on each day of listening, go out on short trips leaving them on, otherwise switch of.
I do this partly as the electricity supply in Spain can just go of, and back on with no prior warning, partly the amount of new construction going on and muppits dig out the cables in the road etc.My amps seem to have a thermistor, as the sound from the 300b's is delayed by 30 seconds, when you start to here the background hiss coming on.
I have had hassles in the past with cheapo standard issue Sovtec rectifier tubes and Golden Dragon 300b's just going and shorting out.
My view, go for sonics, but also check out the reliability of the valves. Many are not too good, particualrly the cheaper alternatives. It just don't make sense buying budget tubes if there could be possible damage downstream.
Other thing I guess, is have the amps checked every couple of years, and visually check the insides yearly at least, aspecially if you have a tube go. Cap leaks and transformer oil leaks can be easy to spot. And if you live in a damp invironment, look out for green corrosion marks, particularly if stores away for a while.
And all NOS valves should be carefully examined before use, cleaning the pins with alcohol and silver polish. look through a magnifier for loose connections etc. I had a calapsed D getter on a Tungsol the other week, nearly popped it in!
