Don,

Looks like I'll have to do that as it is happening on TUNE. I was trying to elimate all the obvious problems first.

Colin,

Does the K3 shut down operating into a dummy load when TUNE is selected? If so, then there is a problem with your K3 - contact support.

If it operates fine into a dummy load in TUNE, then suspect a PA temperature problem.

It may be that you have a bad PA, but again the folks at K3support can help you with some checks to determine the real source.

Mike,

Ignoring the mode in use, into a dummy load the K3 is shutting down at power in excess of 40W on tune.

I'm using a 40A PSU and a new factory made power lead. I am beginning to suspect the PA.
