[Elecraft] [K2] No power on transmit

I have completed the last assembly steps leading to Alignment and Test Part 
3 and started the testing.  Everything went OK until I keyed the transmitter 
(using TUNE) at 2 watts.  The most power I can get on the internal power 
meter is .5 watts.  I do see the current draw rise to about 0.44 amps (from 
0.22).  Adjusting L1,L2 have no effect so there must be a problem in the RF 
circuit somewhere.  The receiver stil works fine.  I looked at T1-T4 but I 
don't see anything wrong with the windings.  Anyone know what the most 
probable causes are to start my troubleshooting phase?  BTW I used a 50 ohm 
dummy load rated at 50 watts.  I will admit that installing T4 links was 
extremely difficult due to the closeness of other components.
Thanks
