Hi guys,

I am looking at 5-year-old used multi channel amplifier(Rotel).
Because this is my first power amp, I am not sure how it will last(life span).

Can I use power amp for for a long time(like more than 20 years)?

Thanks,

    5 Years? That has a lot of life left, just take good care of it and it'll be good to you. Is it a RMB-1075?

    Some the amps I own are 20+ years old and still going strong. Some even sound better that some of my newer ones.
    Don't sweat the age, just the condition of the unit.

    There might be a way to assess the probability of a failure.
    using a Measurement such as "Mean time between failure"

    a multichannel amplifier has numerous components
    and just a single component failure would have an adverse effect on performance

    dirt, dust, temperature variations, humidity, power spikes etc...

    enjoy and when it breaks consider your options to repair or replace.

    At the moment I'm running a 20 year old Kenwood integrated amp (original owner--yours truly) on some SDAs and it sounds better than it ever has on other speakers...it is rated to 4 ohms.

    I had a Rotel that lasted about 18 years. It probably would have lasted longer but it got daily use!

    My Nikko Alpha VI is going on 30yrs old & performs like it's right out of the box. At 300w (dual mono design) this puppy puts out some serious power!!!

    That Nikko looks 'mint'! What do you do to the outside?--it looks like my car after a good wax! Very NICE Pearsall.

    (cfrizz) is right! I'm second in that line.

    I have a thirty-two year old Tandberg receiver that is hooked up to a new pair of RTiA1 speakers and doing well!
    Don't forget to enjoy the music...

    Truth be told...I haven't done anything to the amp. I think it's the lighting from the camera that picked up it's original shine. And yes this puppy is absolutely "Mint", everything is still original & working as if I just bought it. I'd better knock on wood as I say that. So it looks like the life line of electronics can be a very, long time.

    They key component that you can usually match a time frame up to is the power caps tend to go around the 20-25 year point...although that's not an absolute. There are many factors.

    That's one of my concerns...going on 30yrs now & if they go I wonder if I can even replace them & at what cost? Other than that...this puppy is playing like it's a newborn pup. I'm keeping my fingers crossed.
