[Elecraft] Problem with KPA100 - HiCurr

[Koert Wilmink]

Dear all,

After a lot of checking and checking I still have this problem. I  
removed T4 and did dubble check. I did replace the coax cable by a  
teflon coax cable. I did set R26 and R27 to 43K. Sometimes when  
turning C1 it is possible to set 1.0-1 but than it reduces the power  
to 0 watts. After switching off and on again the display is saying Hi  
Curr again.
Any other suggestions?

Dear all,
I just finished my KPA100. I do have the following problem with the  
first steps connecting the KPA100 to my K2 #05618.
I've connected the ribbon cable, speaker and RF connector to my K2.  
I've got audio and I also receive stations when I connect my antenna.
With my dummy load and after setting power to 5Watts on 40M I see the  
5 watts and the SWR for 1 second in the LCD screen and then the HiCur  
(High current) appears on the LCD.On 20m bands I only see the PWR in  
the LCD screen without the SWR for 1 second and than I see HiRefl. On  
10M I do see the pwr and the SWR! The latter I only get 2.1 watts when  
set to 5 watts.
Please can somebody tell me where to start? I did check the  
connections and this seems to be ok. There is no pwr to the KPA100 so  
everything is bypassed, except the bandfilters?
help is very much appreciated!.
