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

Funny you should ask...I had a Krell CD-DSP that was updated by Krell to Mark 2 status. I packed it in the original box and stored it in the garage for a couple of
years. When I unpacked it, it only worked as a transport.
I sold it to someone who found the problem. One of the
chips was rusted and needed to be replaced. My advice would be to store high-end items where temperature variations are at a minimum.

Well I have been in touch with the 300s amps for sale and one in NY wants $3500 and it has never been serviced and sat for 5yrs..he wont budge
the other was $3600(no box) and sat for 3yrs in plastic untouched??

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.
