What about hybrid gear?  I could see turning off triode amps, but what of tube/ss hybrids?  I bought a Butler TDB-3150 and am wondering if it should be turned off at nite or when I'm not home? 
Turn it off when your done Rob....the tubes play a small part in its sound...and.....it really never gets hot....just slightly warm.

Aren't the tubes sorta hardwired into the amp?  You can't really roll tubes like some other ams can you?  How long do you typically let it warm up before you listen?

Here's the deal- I bought the amp new from HomeTheaterDoc here at AC.  But he forgot the manual and is shipping it separately, so I'm waiting on it.  Wonder if it's online?

Yes, your right....no tube rolling Rob.

I listen as soon as I turn it on.... :lol: ....then its on for 4 to 5 hours.

From those in the know....Shane is a very good dealer. As for a manual....I have the 2250's....never read the manual.....just plugged them in, turned them on, and started listening....liked what I heard.

Happy listening......3150 link...

Thanks, Chris- I forgot to check Butler's own site. :oops:  I've only had an hour or two to listen, but so far I'm very impressed.  It really is nice to have some tubes back in the system. aa  Tons of dimensionality, gobs of air and detail, it's pretty sweet.  Moving into a smaller house here in Watertown forced me, sadly, to dismantle my dedicated 2CH rig, so while I'm left with just my HT rig it has to competantly perform double duty for music and HT.  The weak link is being forced to use a receiver, but nothing else will really run my rig- I need the video upconversion and digital decoding modes to properly use my stuff, and comprehensive bass management for all sources. I'm aware of nothing out their under $4,000 that will do all I need, sadly.  I've considered a McCormack MAP-1, but it doesn't do video or bass management.  The Margules Daeleth has long intrigued me, but it's not easy to find a dealer.  I saw one on Agon a few weeks back but it was sold before I had a chance to score it.  It doesn't do video upconversion nor handle hdmi/dvi/component, but it does everything else I need.

Anyways, I can't say anything definative about the Butler til I use it for awhile, but it seems to be a wonderfully synergistic mate for my Monitor Audio Gold Reference speakers.  Electrically it's dead silent, but I'm getting a little buzzing somewhere...it's faint but it's there.  Could be grounding with something (I have a LOT of stuff plugged in), noise somewhere, a loopy transformer...tube microphonics?  I'm not sure where it's coming from and it's too late tonite to monkey with it.  Probably not a big deal.  I'm used to tracking that crap down having so much wiring and cabling. :lol:

Just a note, that running gear 2 years straight means approx 15,000 hours of tube use.

As a newbie to tubes(1yr), I just wouldn't trust leaving on something like tubes that gets very hot, I turn my amp and preamp off when I leave the house, and when I sleep. When I have solid state in the system I usually leave them on 24/7.
Plus, now that I got some NOS tubes rolled in, no way am I just letting them burn without using (listenning to) them.

Two main reasons to leave your tube gear off:

1.  You will drastically shorten tube life.   If you are one of the people
who has invested a bundle in NOS tubes, you are literally burning your
investment up!

2.  Rarely, a piece of tube gear can have a catastrophic failure and this
could result in a fire!  Doesn't happen often, but every now and then a
fuse doesn't go fast enough and you have major problems!

Most gear only takes 20-40 minutes to really warm up and get fully into
its character, where SS gear can take a bit longer.
