Augh, so many nice HT Amps

As owner of one, here are my answers:

1) No. They get warm, but not enough to burn on touch.
2) Nope. The unit gets hot overall, hottest on the heatsinks, but not enough to burn on touch (you can get the palm of your hand fully across the heatsinks and leave it there).
3) Yes. Remember, this is a SS amp with a tube preamp. The manual says the unit is not supposed to be left always on as is the case with your typical SS amp. I guess leaving it always on would shorten the tubes' life unnecessarily. Since there are tubes only on the preamp stage, they have a long life anyway.

Hope this helps.

Yeah, preamp tubes last a long time, or so I'm told.

And regarding burning, just think of it as a lamp. Tubes are essentially like little light bulbs... how hot a lightbulb is, that's about the same for a tube.

Yes, except the tube is rarely outputting 100 W continuous, or 75, or 60 or 40, etc like a bulb would be . The heatsinks on my Logos get way way hotter than the tubes.
