[Elecraft] No power output after upgrades and mods

[K8RS]

Gurus,
        After upgrading the K2 firmware to 2.04 and 1.09 and adding the
K60XV,  I have no power output on transmit on any band (160-10)!
        The receiver seems to work fine.  The display recognizes firmware
2.04 and 1.09.  I have a sidetone.  I am able to activate all 6 transverter
sites and have peaked the 60M and 40M bands with a noise generator. BUT when
the power is set to 2 watts, it drops to 0.4 watts when I press TUNE.
         I have re-checked the resistance on the collectors of Q6,Q7, and Q8
and they are all above 1Meg.  The voltage on Q6, Q7 & Q8 is 13.3 vdc on
Recv. Q6 drops to 13.24 when I press TUNE and Q7 & Q8 drop to 13.26
         I removed the SSB Adapter and installed jumpers at J9 and J10 and a
.001 (102) cap between pins 5 & 12 of J11. I also removed the K60XV board
and installed a jumper between pins 3 and 5 of J13 and a 4.7 pf cap between
pin 1 & 3 of J15 in preparation for signal tracing.  This allowed me to
check the key down signals on U10 pin 4 (0.018vrms) and U9 pin 6
(0.021vrms).  I don't know how to interpret the low reading on U9 pin 6.
         Nevertheless, I tested W6 and got a reading that started at .016,
rose briefly to .297 and dropped to .016 again.  Likewise, D1 tested at
.016-.302-.016.  My Fluke 77 DMM reads .001 with the RF probe leads attached
to nothing, but reads .020 when the ground lead is attached to the K2's
ground. I am not certain that it is working properly.
         So that is the story.  What do you think is happening?  I have
checked for solder bridges, component value errors and cold solder joints
and will continue to re-check each step of the upgrades and modification.
               Thanks,
