Are you certain your AC outlet is grounded?
Yes.. 2 of them are plugged in the same line
I assume that each amp is on it own's circuit/breaker?  If that is not the case, that is your problem.
It has its own internal breaker, this happens when I turn it on, not when its playing
I had a 400cx and it made a click when powering up when the breaker would activate the circuitry to on status. That's normal.

That confused me. A breaker that keeps tripping on the unit itself means internal problems.
Does this happen with both mono amps?
Krell makes a "Krell Link" that you can use for delayed startup.  I use it on my system so the pre-amp starts first, them the amp.  These amps draw a lot of current when they first fire up.  It may be not getting enough juice at startup and shuts itself off.  Perhaps try starting the one amp by itself and see if it stays on.  If not, could be the amp of course. If you feel you need service there is a fellow that used to work at Krell that has a repair facility.  I believe it is The Service Center, owner Steve Lacrone (spelling?).Google it.  He is very helpful.

It is a major issue because that breaker is the amplifier/speaker protection. If the breaker trips with the speakers connected and stays on with the speaker cables disconnected, it is probably a short in the speaker and not an amplifier issue. If it trips without the speakers connected then it's an amplifier issue (i.e., DC at the output, internal short or part of the protection circuitry damaged).

It's going to need service to find the cause. A local repair guy may not be able to help without a schematic.
Thanks a lot guys, ive been looking for the schematics and i cant seem to find one, any help...??
