Do I NEVER shut it off…?

Gryphon says in the instruction manual to leave the amp on. (Diablo 300) 

It sounds amazing and never shuts down, but gets almost too hot to touch on certain parts of the side heat syncs. 
Really…? Leave it on all the time…?

What do you guys think…?

Thank you…!

@invalid,  that’s really invalid to leave tube amplifiers overnight on. 
It’s fire hazard

It's a tube preamp, doesn't run hot you can touch the tubes. I've had the same tubes in it for over 3 years.

Yes, shut it off, especially when going away or not listening for over a week. You are just wasting electricity. It only takes about a half hour roughly for most things to fully warm up. Class A may take up to 90 minutes to sound its best.

invalid,
preamp tubes also can get short when go bad and cause unexpected fire hazard issues.
always better safe than sorry.

The only piece of audio equipment that ever came close to starting a fire was a carver receiver I had in the late 1980's, it shot a big flame out the top cover, so I suppose if I would have put a magazine on top of it there might have been a fire.
