Ron,
If you are certain it was producing near to full output with the KPA100
installed, then I would conclude that something happened when you removed
the KPA100.
I would be looking for something like a short in the coax or its connector
or something equally 'dumb' like that. OTOH, Hi-CUR usually does indicate a
problem with the LPF, but if it is showing up on all bands except 80
meters --- that would mean that all the other low pass filters suddenly
changed, and that is not probable.
Perhaps a bit of wire came loose as you removed the KPA100 - try a bit of
'upside-down shaking'.
Did your power supply voltage sag somehow? Do you still have a nice low
resistance at the power connector? Look for things of that nature before
digging too deep into the K2 itself.
Perhaps it will be more clear after a bit of rest. Good luck!

Hi,
I have been building a K2/100 for a friend, and it has all been going
very smoothly....until tonight.
I had the amp installed and it put out the output it should on all bands,
but I didn't have the power calibration as good as I liked so I took the
amp out, removed the shield and set it up along-side the K2 ready to
adjust.
Set to 5w, press tune on 40m and the HI-CUR warning comes up. I then find
it does that on *all* bands EXCEPT 80m.
I take things apart and find it is a problem in the basic K2 ( #4506)
Time for bed here and I am not thinking straight, but that has me bluffed
at present.
