Cool it!

Being an EX Sous Chef I will suggest fanning the air "away" from the amp.

Sucking air away from a hot spoon is considerably more efficient than blowing on it.

"Sous, sous, sushi...."

Sorry, old Tubes number....couldn't resist.  Spouse is hooked on 'food porn'....'Chopped', Beat the Flay, Wurst Kooks....all that....

"OK, 'chefs'....for our 'alien entre'....Open that basket....if you dare...."

*horrible screams and sound of crunching bones...*

"Well, I guess the chefs are on the menu tonight..."

Which Krell do you have.  I have the KSA-80B and while it runs warm, it does not get hot.  Perhaps refer to the owners manual and see what they reccomend for a temp.  Does it trip the fail safe?  I drive my one Ohm Apogee Scintillas and I have never tripped the saftey.  It might be that your amplifier needs to have its bias adjusted, or perhaps its time for a tune up.  I had mine rebuilt at the Factory about a year ago.  You might also call Customer Service at Krell and ask them.

I use the same thing and it works great.  Comparatively speaking, pretty inexpensive, too.

Play cool jazz.
