Question on a Levinson 27.5 amp

My Class A amp's power switch is on the back panel, with a standby switch on the front. Made c.1993 and still as sweet as it ever was. The Lev's build quality is surely comparable to my Bel Canto.

What does the maker suggest?

I really couldn't get a straight answer from them, although it was via email, so maybe I didn't communicate it very well. I guess I would prefer to keep it in 24/7 since I feel it takes about an hour of warmup time for it to achieve the large 3D soundstage that I have enjoy. As long as I am not shortening the life span. Then it is not worth it. Thanks for your replies.

Another happy owner of a 27.5 here.Mine was bought from new and still has low hours.I enjoy mine on weekends and of course I turn on before listening session and off once I am finished.Never had a problem yet,knock on wood.Great amp,actually I am looking for another one in the used market with plans to bi-amp with my existing one and use my Rogue M150 on the mid's and high's .
Beemer with all the respect your ML-3 is way older than the 27.5,is it not?
Tripper I would't call the LEGENDARY Mark Levinson comparable to Bel Canto,then again I never actually seen a Bel Canto in real life.Hard to imagine though.
Enjoy your systems all.

I feel obliged to reply...

Few months ago I was running 26 & 27 (not 27.5); not anymore...

I used to turn the 27 on and off, but in the end just left it on all the time. One day I came back from work, one channel was blown.

No sound. Just a dead hiss.

I bought mine from an authorized dealer almost 15 years ago before I moved here, and whilst the dealer in Sydney is happy to look at it, that's 1000km from where I live.

"Just as a general principle we recommend that preamps be left on and power amps turned on when needed but the choice is yours. We don’t have a service agent in Melbourne for Mark Levinson all Under Warranty service is done in Sydney where we have a very experienced ML technician. You could however have a chat with Barry Clarke of Sound Electronics on 03 9725 8992 who can have a look at the problem for you.

Now it's sitting in my store room. The sound was smooht and sweet, and one day I'd probably lug it somewhere to get it fixed.

But no, I wouldn't leave it on all the time. It's one hour of warm up time. Like you see above, if something goes wrong, you are really to blame...

Kowkow, please forgive me if you already did this, but did you check the fuse on the "dead" channel?
