  Question on a Levinson 27.5 amp
I am wondering what is going to shorten the life expectancy of my Mark Levinson 27.5 more, turning it on/off several times per week, or just leaving it on? The benefit of the latter is of course, no warm up time, but if I do that will the amp start having problems a few years from now??

Thanks

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.



Best regards,

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...
