Krell KSA250 need services? When?

If it seems fine and is only used a few hours a week, it is probably OK.
If, to make you feel better, you can call Steve Leckrone at Krell. His word, would be the final word.

One day in the future you will push the power botton..the blue light will come on: BUT, you will not hear a click! Thats how a lot of Ksa-250's wind up back at Krell. The protection circuitry will be engaged and it will be time to go in for the full treatment (about $400). Mine went in about 1.5 years ago..shipping is about $150 air (one way), thats the killer!! Use Krell's shipper when the time comes, they will give you the number and I think they are called Ocean Air.
