Evening gang:

Having some fun with my K2 these days.   I've been attempting to set up my 
new K60XV and XV50.

While trying to set the inductors inside the XV50 I noted I wasn't getting 
enough drive from the K2 to bring the voltage up where it should be.

Back to that later !

Now I'm seeing high current in the K2.   5 watts output show nearly 4 amps 
draw.     OUCH

Checked Q7 and Q8 and dang if my collector voltage isn't dropping way down 
on both.  Q7 drops to approx 6.5 volts and Q8 all the way down to 3.5 volts.

Dang it !                Checked Q11 and Q13 and the collector on Q13 is 
also low.  I'm headed to Elecraft to order the PA kit for repairs. 
Anything else I need to be checking ?????

FWIW        K2 still putting out approx 8 watts but current is way up.  I'll 
assume the PA will fix my problems and I can go about figuring out why the 
K60XV represents such a high SWR.

I did recheck the I/O for the board and that was good.

OH Well !     One thing at a time !
