Is it good for a Krell to SIT for 3-5yrs

At this price range I would look at something like a McCormick 500, there is one on here now for $3495. Much newer and .IN MY OPINION, would sound better.

I was in touch with Adam,the one for $3500 and he thinks it doesnt matter that this amp has a destoyed box($300) and never serviced($1300+shp) in 17yrs.He figures that tough luck for someone I guess.

I woldn't worry too much if the amp still works. If anything, caps dry up faster (due to heat) when the amp is used ! The life expectacy of every cap shortens with temperature.

Large capacitors lose their form over time and no use. I don't know how to explain this further. I'm an electrical engineer, but I'm tired and my brain isn't on yet I guess. If amps sit for an extended period the capacitors will degrade and when subjected to voltage later, they may and probably will fail. This is why it is always good to turn an amp on every few months if they are in storage. to charge the caps and have them keep their form. It is very easy to check. Have a technician use a variac and slowly bring the voltage up to nominal voltage and let it sit for awhile. A slow charge sometimes will allow the caps to re-form if they have been sitting for some time. After that, you are good to go. However, I would not recommend plugging it in and just turning the thing on if it has been sitting for a long period. Slow voltage increase with a variac is the way to go.

Yes!!! Krell is not at its best unless properly aged in a "Krellar". This is similar to a wine cellar with controlled humidity and temperature. The serious audiophile keeps storage records and carefully monitors his stash so as to not mature the critical Krellulites at too rapid a pace.

If you have heard a bad sounding Krell it is because the owner did not take these precautions. I thought everyone knew this.
