[Elecraft] K2 Won't power on

[Don Wilhelm]

Jeremy,

 From those resistance readings, I would say you are OK.
If you have all except Q7 and Q8 installed, do a TUNE and re-check the 
voltage on the base solder pads of Q7 or Q8.  If you do not see a 
voltage between 6.2 and 6.4 volts, replace Q11 and Q13 and retest before 
you install Q7 and Q8.  You don't want to destroy new PA transistors 
with too much base voltage.

You can make measurements without the heatsink when Q7 and Q8 are 
removed, but once Q7 and Q8 are mounted, you must have the heatsink 
installed if the PA transistors are expected to last longer than 30 seconds!

73,
