K2 super kit, but new problem !

F5UL
Hello the list !
I just finished K2 #4498. it was running all test in good condx and Rx and Tx where in the specs.
I let it in stand by this morning on 7 Mhz and sudenly I read HiCur on and off. I put down the power level and I still got HiCur any time I close the keyer or put it in Tune. Power level = 0 in display I = 2.45 A. with curent limit set @ 2.5 A, whenever I key it in tune or with the keyer.
First suspects the two 2SC1969. removed and changed for 2 others. No change !

And I forget the principal : reception is gone !!!

So please help !!! I will accept any informations !

F5UL/Robert

Robert,

Find the unsoldered connection.  It is somewhere.  Contact was present when
everything worked before, but has now moved loose.

Work on receive first, then after that is working try the transmit section.
Careful examination of the T/R switch area is a good starting place. Also
check the Low PAss Filters and the antenna jack, but the unsoldered
connection could be most anywhere.
