I try keeping the temps in the house like Ozzie and harriet enjoyed. They always seemd to be wearing sweaters in every episode. Ricky? Not so much.
Having been deep into industrial electrical affairs including communication equipment for some years, having electronics energized indefinitely never seemed a negative consideration, PROVIDED the temperature surrounding it or them could be kept constantly lower.,
400Hz motor Generator sets, PA systems, etc., amps we used had huge output tubes and the gear necessary for them to operate were kept in a air conditioned space which was always brisk. 60F or less..
Experience proved maintaining lower temps kept these amps trouble free so far as I knew from being there over six years. Never wass one output tube replaced. Nor was there any failures otherwise. This information covered several venuews utilizing the same or similar gear.
At worst, a semi annual opening and thorough removal of dust and dirt accumulation was the only active function required beyond keeping operating temps low and constant..
It’s the main reason I have for keeping electronics apart from the listening area. So they can be kept at a lower steady temp. it amounts to use of an adjacent room and longer spkr cables, and oh, yeah, a dedicated AC unit just for that room.
A very prominent designer of very well regarded power plants once said to me heat kills. The lower you can keep the operating temps the better given the temps enable optimum performance of the amps.
It did not take long to see what temps the amps he made liked as ambient temperature.
Even a tiny little fan can be of great benefit if well placed.
RWV… so perhaps this or that item may take as long as two days under power, though I’d not suspect periods further than that were at all required for ANYTHING.
Those items whose endorsements say “leave on’, appear to be able to do quite well after run in with just a day or so of being re-energized. As was said, engage it all for an hour or so maybe less, and have fun. My SS amps took longer than my Tube amps but only by 30 mins, SS needing more foreplay apparently..
Makers are simply tending to having their caps fully loaded and other areas stabilized in terms of temps and energy.
On another note and not meant at all as disparaging, makers ideas of YOU having on THEIR GEAR at all times read as forever, is not hurting them at all, is it?
IMO, its one of those take with a large grain of salt thingys, as there are alternative means for extending the life of our energized components with simple cleaning and temperature control. Or by simply powering up periodically in advance of listening sessions on the primary system.
With a $900 HT rec I’m not really worried as each one I’ve owned has lasted easily ten years without issue prior to needing once a new IC chip.
With $30 to $$$$$$ worth of electronics , I’d seriously consider finding a way to keep that investment operating safely by maintaining a lower environmental temp. MO.
