[Elecraft] K2 PA

[Aaron K5ATG]

I just replaced the PA's on my K2. I replaced Q7, Q8, Q11, Q13 with parts
from the Elecraft PA Replacement Kit.  I have done this in the past with no
problems. Power is supplied from a switching power supply that supplies
power to a power distribution box that has a fuse for each output. This
distribution box supplies power to a small 2 meter 70cm mobile/base radio
and a LED light strip. This setup has been working with no trouble for a
while. Now as soon as I plug in the power cord to the K2 all of the power
coming from the distribution box shuts off. I used the same power cord on
two other radios and it worked just fine. So the problem lies in the K2.
While working on the K2 I messed with replacing only the parts mentioned
above. I went over the PA's with a magnifying glass looking for solder
bridges and other faults and could not find any. This problem did not exist
before I changed the PA's. I would appreciate any ideas as to what may be
the problem.
