K2 trouble

Mike, W9QS
I have a problem with the first part of section 3
testing.  I set the power level to 2.0.  When I press
and hold "tune"  I get "HI CUR" on the LCD for about
1/2 second and power is at .1.  Nothing seems to be
warm.  Q6, 7 and 8 all seem Ok and not shorted.

Anything I might have missed before I start taking it
all apart again?

Look for solderbridges or components that has no conection around the Low
pass filter and PA transistors. Specialy Q7 and Q8. It's easy to forget
soldering an pin on the relays.
