Joe,

Make sure you are looking at the correct pins.  U1-13 and P2-6 are 
connected by a 100 ohm resistor.  That should not be open unless R1 has 
failed open. And -- make these measurements with the KFL1-4 removed from 
the radio.

BTW -- I had a similar problem that developed over a 3 day period on 20 
M -- went from 7 W output to 2-3 W.  I did a re-alignment and have since 
replaced my original Wht trimmers by Blue ones (just today in fact).
