just been listening to Radio 2 on Freeview. Sublime sounding. Pity about the headphone socket.
Mind you, can't keep it on any longer than an hour. The heatwave has played havoc with the amp. Usually keep it on for between 4-6 hours without a whiff of heat, at the mo 60-70 mins is the max. Throwing out quite a bit of heat.

Your loyalty to Leema is endearing PP but I would be wondering why it keeps going wrong quite so often. The cynic in me says that their customer service needs to be good if the kit falls over all the time!
"Keeps going wrong quite so often" and "kit falls over all the time". Eh? This is the 2nd time in 3 years. Sure this isn't the case generally with their products, just a bit unfortunate that the headphone socket seems a little temperamental.
This shows something is very wrong. I've never had to shut down any amp due to heat. (And we've had hotter weather than this in the past.)

That does seem worrying, hopefully Leema will give it a good going over when they get there hands on it.

Twice in three years sounds an awful lot to me! Of course anything can fail but with modern electronics I would expect a very low failure rate.
Well there also must be something up with Rega too. Steve was saying a couple of days ago his Brio-R has been getting very warm in this weather.
If it had issues with the sound from speakers I would be chuffed off. But it is confined to headphone socket only, which gets little use. Not ideal but that's the way the cookie crumbles.
It's not 'something up with' an amp if it gets warm or even hot.
Lots of amps get warm during normal use (hence heatsinks and recommendations to keep amps in a well ventilated space), but they don't need powering off after an hour as you said about your amp.
You can fry an egg on top of a Sugden A21, even when it's idling, but that's normal (and explains why about 30 percent of the amp consists of heatsink).
The Rega Elicit-R instructions clearly state...
"The Elicit-R amplifier will work well on most surfaces, such as a shelf or a table, provided there is sufficient air around the heat sinks to prevent overheating."
"Do not touch the heat sinks They can become very hot."
They do not tell you to turn the amp off after 60 minutes.
Why are you turning your Leema off after an hour?
If I remember my 'O' level Physics correctly Newton's Law of Cooling says that temperature loss is proportional to the difference in temperature between the heat source and the environment. So if the heat sink were at say 50C and normal room temperature is 20C then that is a loss proportional to 30. However if the room is at 30C then the loss is proportional to 20, ie only 2/3 as much cooling. This implies that it would be sensible to be careful with equipment in this weather!
PS I also recall that the loss goes up to being proportional to the temperature difference to the power 4 if there is a breeze so having a fan near your equipment should have a major cooling effect.
PPS I shouldn't have mentioned the fan because I expect there will be a thread soon about how a particular fan improves the sound stage.
Had my Brio R on all morning, its very warm - all down to ambient temperature isnt it!
Its been 28c in my lounge lately - today is a bit cooler at 22c but my amp is still warmer than usual, however I am not worried at least I know its doing a good job and don't all amps run hot?
BTW re: PPs Leema - really think people are getting a bit tetchy about it - it is one of those things isnt it! My Panasonic GT50 dies after 3 months due to a faulty PSU - thank god I got the free 6 year warranty, it was repaired locally to by an independent - they even collected/delivered it as its a 50", cant say fairer than that & 5 yrs 4mths left on the warranty!

IMHO amps getting hot is not a fault, you shouldnt need to turn it off
