I just performed the KPA100 cap mod to as I had a HiCur indication.
Replacing C80 and C81 did not correct the problem. After the mod I am seeing
the following indications as read on the K2 display.

KPA100 off 20 meters
12.8v 2.62a 13.7watts

KPA 100 on 20 meters
11.9v 4.04a 98 watts

The power supply is delivering 13.2v key down with the KPA100 as measured at
my DC distribution point.

I have checked all of the solder joints on the KPA100 input network. No
problems were found. Operation on other bands seems to be OK.

Any help is greatly appreciated
